The results of application of nanotechnology in construction and building materials.Vadim V. Maltsev, Doctor of Science,

Academy of Natural Sciences, the chief ecologist wooden housing, scientific and technical director.

This report presents data on the effective application of nanotechnology and nano-objects in the field of building materials and construction, during the past 10-12 years.In his work, we used three types of nano-objects:Nano grinding special chemical powders with particle size after nano grinding from 100 to 500 nm;

Aqueous dispersions of copolymers modified special additives (flame retardants, preservatives, antifreeze, etc.), with the size of the dispersed particles of 60 to 300 nm; Modifying chemicals (liquid) with a particle size of 2 to 8 nm - High plasticizer of PVC and vinyl chloride copolymers, plasticizers - flame retardants, water-soluble flame retardants, heat stabilizers, liquid PVC.I. Nano grinding powdered chemicals.For nano grinding powdered chemicals used special ink nano shredders providing initial rate of acceleration of particles up to 300-350 m / sec. Nano grinding subjected some powdered chemicals - flame retardants and antiseptic, but given the time frame of the report I will focus on just one, widely used mineral flame retardants - detoxifier with the trade name "Algid""ALGID"

Non-toxic fire retardants FOR MINERAL LIGNOPOLIMERNYH and resins TU 2386-007-00249567-94

Non-toxic fire retardant mineral based metal hydroxides to ligno materials, polyvinyl chloride and copolymers of vinyl chloride-, synthetic rubber, polyvinyl acetate and vinyl acetate copolymers,The greatest effect of increasing the fire resistance of polymer materials is achieved by the joint application of "ALGID" liquid and solid phosphorus and phosphorus-chlorinated plasticizers and some types of chlorinated compounds. For example, the use of "ALGID" in fluff PVC materials (pipe Vinyl) with phosphorus-chlorinated flame retardant plasticizer such as "ANNAFOS" and with the addition of boron-containing preservative-retardant type "BORANS" allowed us to obtain a material with an oxygen index of 32-33. A similar value of the oxygen index was obtained by creating slow-burning PVC linoleum for the railway, which included "ALGID" is used in conjunction with liquid - solid and phosphorus flame retardants, plasticizers.

It is particularly important to note that in these compositions and materials "ALGID" used instead of toxic, deficient for Russian consumers and costly antimony trioxide. Thus, the industrial application "ALGID" in the production of flame-retardant polymer solves an important ecological problem - eliminate pollution plant and environmental toxic dust antimony trioxide. "ALGID" brand "B" 8-14% humidity, "ALGID" brand "BV" moisture content of 1%.Specifications:Appearance white odorless powderDensity 2.42 g/cm2Mass fraction of fractions of less than 200 nm.,%, Not less than 80Specific surface area, m2 / g, not less than 14Moisture content,%, not more than 1.0Loss on ignition (1100 ° C),% 34,0-34,8pH of the aqueous suspension (10%) 9-10.5 Mass fraction of iron oxide,%, not more than 0.06

Learning processes nano grinding Algid and other mineral chemicals showed that serious difficulties arise from dusting nano grinding objects. Similar difficulties arise in practical use nano grinding powders in industrial processes. Since we are always interested in not only experimental, policy decision, but also a real practical way in technology, have been studied the possibility of "wet" and "dry-grinding." If the chemical is planned to be used in water systems - latex and adhesives, preservatives, aqueous solutions of polymers - that nano grinding produced in water - water paste or powder, moistened with water. If you want to use in the chemical composition of the hydrophobic, the nano conducted in liquid component, such as a plasticizer in the medium used in the processing of PVC compounds.Specifically Nano grinding Algid was used in the development and production of slow-burning, frost-resistant, weather-webs "Kronas" on the basis of PVC plasticized with a plasticizer - flame retardant "Annafos"

"Kronas"NEW nonflammable,

Weather-resistant roofing materialIn order to ensure the construction of a light and durable roofing material, has been

developed composition and technology of slow-burning and weather-roll roofing materials based on plasticized polyvinyl chloride and special polymer modifier. When you create a material Kronas effective flame retardants have been used, including a new fire retardant plasticizer Annafos-3 and ground to nanoscale inorganic flame retardant

Algid. To prevent the material aging system was developed light stabilizers and UV - absorbers. A particularly important part of the design was the use of a polymer modifier, which provided the material unusual combination of useful performance properties - high tensile strength (up to 11 MPa) and at the same time high flexibility, elasticity and resistance to frost. Combination of properties is achieved, thus avoiding the use of glass fiber mesh reinforcement, which distinguishes material Kronas their foreign counterparts, both in economic terms and in terms of workability. In parallel with the material Kronas developed adhesive sealant for high-sticking Rekoll Kronas material to concrete and wooden base, the strength was achieved at normal separation from 0.6 to 1.0 MPa.Specifications "Kronas":Conventional strength, MPa from 7.5 to 9.5Elongation at break% from 320 to 380Flexibility to the test timber with rounded R = 5 mm, at a temperature of-450C No crackingFlammability according to GOST 30244-94 from T1 to T2depending on the concentration of flame retardants

Nano Algid with nanocrushed antiseptic "Borans" and plasticizer - flame retardant "Annafos" was also successfully used in the development and industrial production of slow-burning, anti-static, Funginertness linoleum on the basis of PVC - "Sudalin" (designed for sea and river vessels)."BORANS"Antiseptic - Fire retardant - AntistaticFor polymer and wood materialsTU 249-004-31585841-95"BORANS" is a white powdery product, odorless, low toxicity, Hazard Class 4.The main purpose of "Borans" - protection of wood against the formation of mold during storage and transport. For antifungal activity "Borans" refers to miko static drugs, ie does not allow for the development of fungal colonies on wood. Before processing the wood "Borans" dissolved in warm water at a ratio of water / "Borans" = 9:1. The greatest effect is achieved antiseptic timber when the material is treated with a solution of "Borans" immediately after production by dipping or spraying. If antiseptic solution "Borans" materials not directly subjected to rain, the antiseptic action of the "Borans" are stored indefinitely, as "Borans" is not volatilized and does not evaporate.Impregnation of the surface layer of wood "Borans" does not prevent subsequent drying and machining of wood and does not affect the appearance and color of natural wood.Borans comes in polypropylene bags with polyethylene liner weighing 20 kg."Borans" was also successfully applied for antifungal protection polymer roofing materials, pipe vinyl artificial leather, fabric-backed vinyl covers. In these materials, "Borans" proved himself not only as an antiseptic, but also as a flame retardant

Successfully used nano Algid (together with a plasticizer - Annafos flame retardants) in the slow-burning, coking under the influence of flame glue "Tetrakoll-Coke."It is important to note that in all of these materials, and write effective nano-Algid (particle size of 100-300nm) increased by 3-4 times compared to Algid with particles 5-10 microns (5000-10000 nm). Similar effects were observed for other powdered chemicals for special applications.II. Aqueous dispersions of copolymers with nanoscale dispersed particles (60-300nm).Aqueous dispersions of acrylic copolymers, copolymers of vinyl chloride and vinyl acetate have been successfully used for surface impregnation of building materials with the surface and the mass-developed system of micropores with diameters from 1 to 9 microns (1000-9000 nm): wood-based materials, products made of concrete, brick , plasterboard and other gypsum-based materials (eg, wood and gypsum board), all kinds of trees and wood-based materials, slate and more. Aqueous dispersions of copolymers that form slow-film (particle size 300 nm) have been successfully used for deep impregnation by vacuum pressure to obtain a solid, durable, nonflammable, water-resistant flooring based pieces of birch and beech. Aqueous dispersions of modified acrylic copolymers were used to cover the aluminum foil and aluminum sheets, including colored water dispersion (particle size 60 nm).The basis for the development of water-dispersion formulations for various purposes has been modified technology of these dispersions in order to make the necessary (given) the relevant properties of the compositions and film formed after the evaporation of water: cold resistance, water repellency, the strength of the adhesive joint, slow-burning properties funginertness, antistatic, etc.Used to modify its own above all chemicals that are produced EkRusHim: Annafos, Diafos, Oksistat, Borans and others, as well as prominent industrial chemicals.

This design of the roof has several advantages:Reducing the cost of rooftop waterproofing floors 3-4 timesRepeatedly reduced the cost of repair of a roof10 times less pressure on roof floor of the premises.Completely eliminated the diffusion of water vapor in the reinforced concrete floorInsulation of the rooftop floor warming is not in need of repair for an indefinite useful life, while the outer insulation is often damaged.

Below is a diagram of water repellency and insulation covering the rooftop of the "Disperley."

UNIT UPPER LAYER ROOF

system "DISPERLEY"

The essence of the "DISPERLEY" ("blanket" or "planar" technology protection of concrete) is to use the body of the concrete floor to create on the surface of the waterproofing layer with very high mechanical strength and frost resistance instead of traditional roofing materials.It uses latex impermeable copolymer with nanosized particles smaller than the diameter of the pores in the concrete. Moreover, in giving this dispersion certain supplements can achieve deep penetration into the pores of the variance concrete slab roof slabs and high frost formed polymer film. This compound is called impregnation. Then layer of latex copolymer, which serves as a primer composition and the concrete surface is formed polymer film. The main purpose - to close the pores in the concrete and ensure a tight coupling of the surface finish of the concrete. After closing time this structure forms on the surface of concrete is quite a strong frost hardy film.

And then this polymer layer is covered twice topcoat - frost resistant, weather resistant, antiseptic DOKAS latex paint that provides a complete prevention of the entry of moisture into the body of the concrete.

The result is a hydrophobic and waterproof layer. You do not need any roofing material. Moreover, processing yield all the bumps and curves of the roof. Where there are joints between the panels of roof slab - their pre-sealed. Sealant is a sufficient number, including domestic - frost resistance and durability.

Roof waterproof material is impregnated and finished the top layer of concrete, and the total weight (dry) of polymer components is 210g/m2 roof.Polymer layer not only makes concrete waterproof, but also strengthens it. And nothing bad will happen, even if it hit him with a crowbar, because pores of the concrete soaked copolymer. The pores are closed, scrap not penetrate into the pores, the place warm hairdryer cleaved and processed primer composition, and then the finish paint.

Every 7 years, updated paint DOKAS in one layer, and it still is.And waterproofing coating that forms on the outside of w / w floors, by weight (of which has already hardened in the pores of the concrete, and formed on the surface) is about 210 g/m2, which is very small compared to any conventional roofing today, the which the weight starts from 2.5 kg/m2, ie different order of magnitude, at least.

Composition - VUPRIN and paint - DOKAS that industrial plants in "EkRusHim" ("Organic Chemistry of Russian") (see www.ecrushim.ru).

Very promising data were obtained in the implementation of the program of replacement varnish for wood floors with toxic organic solvents to water paints. Using a modified mixture of aqueous copolymer

dispersions with particle sizes of 60 nm and 300 nm in size, including the dispersion of nonflammable polymer, able to create and to produce lacquer "Ledor" zero emissions, nonflammable and resistant to

abrasion. It is appropriate here to note another important feature of varnish for wood floors on the basis of water nanodispersions copolymers. In contrast, paints and solvents, water nanodispersed paints primarily

filled pores of the wood, and then to form a surface layer of lacquer. With this in grinding surface clearcoat dirt is not absorbed into the pores of the wood, but remains on the surface. Before proceeding to update the lacquer layer wooden floors do not need to scrape (!), But rather flush grated part of the floor

to dry and apply nov nanodispersion varnish. Trade name developed varnish "Ledor." "LEDOR"

Latex, nontoxic, VZRYVOPOZHARO-safe, one-parquet lacquer and wooden floorsCreating a non-toxic varnish parquet "LEDOR" was necessary to stop the poisoning of the population with highly parquet lacquers on organic solvents, wide ¬ to the country Russia.

The basis of a non-toxic latex paint "LEDOR" are high quality ac ¬ reels dispersion, which in the presence of special additives and fine soaking wet ¬ UT surface flooring, and after drying form highly transparent wear layer.

In the process of varnishing "LEDOR" does not smell at normal ¬ mal temperature and humidity conditions. Varnish dries relatively quickly (no more than 1 hour to 1 layer at 20 ° C, 60% humidity and air exchange one room volume / hour). The preferred method of applying a lacquer "LEDOR" - with a brush, the recommended number of layers - 3-4.

III. Chemicals with nanoscale particles.Among the chemicals that we developed with nano-sized particles should be noted first of all aqueous Diafos-R-50 at a concentration of phosphorus flame retardant 50%. The composition Diafosa-P-50 is also an antiseptic. The following are the specifications Diafosa-R-50.

"DIAFOS P-50"New effective non-toxic, non-volatile organo, a reactive flame retardant for wood,

fabric, and wood fiber ecowool.Organo-retardant "DIAFOS" designed to increase the effectiveness of fire wooden structures, tissues, Cellulose Fibre, fiber. "Diafos P-50" eco-friendly low-emission materials (IV class of danger), the processing and drying the impregnated fabric products and does not emit harmful volatile substances. When processing wood products water solutions "DIAFOSa" with additives to provide flammability group G-1. Impregnation of hydrophilic tissue oxygen index increase to 50.

Exclusive feature "DIAFOSa" is its ability to interact with formaldehyde to form a reactive oligomers, and to join in the copolymerization reaction with urea-formaldehyde resin and to form a polymer water-insoluble retardant. In addition to the functions of the flame retardant "Diafos P-50" acts as an antiseptic.Graduation commodity form - an aqueous solution with a concentration of 50% of the base material.Specifications:Appearance clear aqueous solutionMass fraction of the basic substance,% wt 50Density at 20 ° C, g/cm3 1,245Group of fire-resistance rating 1pH of 10% aqueous solution. 6,7Viscosity VZ-4, sec, not less 12

In practice, to reduce the flammability of materials Diafos-P-50 is used in a pure idea, and as a part of various compositions (Vupreks, Vuprin, Ledor and others). Dilute aqueous solutions Diafosa-P-50 with various additives are used to reduce the flammability of wooden materials and designs, fabrics, including synthetic, paper, wood fiber insulating materials based on flax, furniture foam, etc. The main features Diafsa-R-50:T he effectiveness of the flame retardants uncertainty persists long after the treatment of the materialIn the operation of the treated material Diafos-R-50 does not emit any harmful substances.

After impregnation material (wood, fabric, etc.) do not change the appearance, as the evaporation of water Diafos R-50 forms in the pores of the material transparent nano-and micro-crystals with high mechanical strength and very soluble in water. While studies have shown unusual fact: dilution Diafosa-P-50 with water, first leads to increased efficiency of its action as a flame retardant, despite a decline in the quantity per unit volume or surface of matter (for example, set fire retardant treatment Ecowool). Thus, dilution Diafosa-P-50 with water to 1/1 led to increased flame retardant effect and dilution ½ gave the same effect as a concentrated source Diafos-R-50.

On the following photos show the results of the determination of molecular associates in dilute Diafosa-R-50.

Finally, it should be noted is a very important property Diafosa-R-50 in mixtures with karbmido-formaldehyde resins, it acts as a curing agent, and in the wood-wood panel, he serves as a flame retardant additive and catalyst of free formaldehyde. In combination with the mineral flame retardant "Algid managed to get a slow-burning models with a decreasing time-formaldehyde in mass plate.In the development of slow-burning materials based on plasticized PVC formulations were developed and production technology of liquid plasticizer - retardant Annafos-3 and paste plasticizer - retardant Annafosa-4. A comparison of the effectiveness of these plasticizers - with well-known plasticizer retardants - flame retardants - tricresyl phosphate showed that the composition of PVC linoleum and PVC roofing material Kronas, introduction Annafosa-3 (with Algid) provides the effect of reducing the flammability of 2.5-3 times more than tricresyl (weight loss of samples after removal from the flame of 3-4% against 10-11% of the samples with tricresyl).

The introduction of the mass fractions of the sample is Annafosa-4 (with other similar components) provided lower mass loss of samples after removal from the flame at 0.25-0.4%, which is above anyone and never reached.

In addition, PVC - materials that are composed of Annafos Annafos-3-4, combustion of which gives very little smoke, while tricresyl, included in PVC - materials, combustion generates little smoke generation in Russia do not pass on smoke index "D".Currently Annafos-3 is produced on an industrial scale, and Annafos-4 in the form of pilot batches to order.

For we developed nano-chemicals are also antistatic highly thermal stable Polymer "Oksistat" and spread heat stabilizer for PVC "Rustab-P", but in this report in detail on their properties does not allow the time.

"CHEPLAR"Roofing materials for pitched roofs

One of the most pressing problems of our time - the use of waste and non-recoverable tires. For its solution was able to develop a production recipe unique material, which uses waste tires (rubber powder) and waste polyethylene (film canister, flake, etc.), and the introduction of the flame retardant composition - made it flammable. This material is called - "CHEPLAR" from the words "plastic-rubber shingles."

Material "CHEPLAR" borrows resistance tires to atmospheric and climatic influences, which is due to the following factors:

• Soot, the automotive tire is a powerful absorber of ultraviolet radiation, providing resistance to sunlight.

• Elasticity of vulcanized rubber allows it to transfer good temperature fluctuations.

• The presence of antioxidants prevents aging under oxygen.When you create a composition in the manufacture of "" were used following the

nano-components:1. Mineral flame retardant "ALGID" (100 nm);2. Plasticizer-retardant "ANNAFOS-3" (9 nm);3. Retardant polymer (9-11 nm).Through the use of a 3-retardant above the world's first managed to get out of

impermeable material composition, which is the basis of flour mixture with a rubber from used tires and recycled polyethylene: the material to spread the flames and by the action of an open flame does not form drops, and when setting out from flame immediately dies (time independent burning is 0 sec.)

Was not a simple solution to exterior color of the material. Getting outside of the color on the surface of the material with poor adhesion to all types of dyes used previously, it was a very strong chemical-technical solution. The fact is that, if not only vary the composition of paint, but also the substrate on which it is applied, the results can surpass all expectations. Thus, the binding component was introduced and in the paint, and one of the liquid flame retardants are added to the composition "ChEPLARa." In this way, the common component was a "chemical welding" of the layer surface of the

material and a layer of paint. Ie incredible happened: it was possible to use a water-dispersion paints for coloring rubber surface, and with a plastic filler.

Paint itself deserves special attention. To manufacture it the nano particulate mineral flame retardant "ALGID" and polymer nanoplasticizers. In the paint, called - "DOKAS" used nano-powdered mineral pigments domestic production, as well as a film-forming polymer matrix was used aqueous dispersion of acrylic copolymer produced in Russia. With competitive test paint "DOKAS" (example of color slate) won by a large margin, two international competition, which was attended by leading French, German, American, Belgian and Danish companies. Therefore, if the material "CHEPLAR" occasional touch up paint "DOKAS", it will be eternal material.

Main applications of the material "CHEPLAR":1. As a roofing material for pitched roofs.Material "CHEPLAR" has high mechanical strength and very durable. In

addition, it is very light material (4 times lighter than slate, 10 times lighter than natural tile). On application requirements "CHEPLAR" superior to any variants of metal: not corroded in places breakdown anchors fasteners, does not proceed in these areas, the elastic restoring form, does not allow the heat shrink does not screen electromagnetic fields. Rot, produces no noise from rain, hail and wind. "CHEPLAR" is able to form elastic recovery after removal of the snow load. The projected life of the material of 25-30 years.

2. As an outdoor and road surfaces."CHEPLAR" - the material is not slippery. Therefore, the possible use of this

material - for sports facilities, flooring for livestock farms, etc., ie where you want to create not slippery surface.

Technical Description."CHEPLAR" is a body-shaped "under the tile" roof plate for forming roofing for

sloping roofs. "CHEPLAR" is formed from high-strength, elasticity, cold-resistant and water-resistant synthetic sheet material on special presses. Apply a variety of weather resistant inorganic pigments in the paint "DOKAS" used in the dyeing, allows a wide range of colors sheets "ChEPLAR." The introduction of "ChEPLAR" additives, special flame retardants, can classify it as a non-flammability, from the angle of fire. "CHEPLAR" comes ridge elements podkonkovymi elements corners from the same source sheet.
