The invention relates to construction materials and is designed for protective and decorative finishes building structures and products made of metal, concrete, Kiri, containing SiO2, Al2About3, CaO, K2O, Na2O2About3, R2O5, F', FeO in the following ratio, wt.%: Al2About34-7, CaO 4-5, K2About 1-4, Na2O 4-7, In2About35-8, P2O58-10, F' 0,3-0,7, FeO 4,0-5,5, SiO2- the rest (see RF patent 2057091 class IPC603 With 8/08, prior. 15.05.92, op. 27.03.96).

The disadvantages of the known glazes are high temperature melting Frits - 1200oWith high firing temperature of 850-900oC.

Known composition for a protective and decorative coating of building structures and products, including synthetic latex, a water-soluble polymer, ethoxylated alkyl phenol and water; as the water-soluble polymer it contains caprolactam, or hydrolyzed polyacrylonitrile, or a mixture in the following ratio, wt.: synthetic latex is 87.5-97,5, water-soluble polymer is 0.5 to 10.0, ethoxylated alkyl phenol and 0.2-15, water - other (see RF patent 2045502 class IPC604 In 41/63, 04 26/04, prior. 14.05.92, op. 10.10.95).

A disadvantage of known composition is a low strength of the coating at high temperatures.

Known composition for a protective and decorative coating on striatal polymerization and water; as a film-forming component used polyester resin as a binder is a polyvinyl acetate emulsion, as a plasticizer - diethylene glycol and butadiene-styrene copolymer in the form of glue "Bustilat", as a polymerization initiator is ammonium persulfate, in the following ratio, wt.%: polyester resin 5,0-20,0, polyvinyl acetate emulsion in the calculation of dry matter by 30.0-60.0 sec, diethylene glycol 2,0-15,0, glue Bustilat calculated on dry substance of 5.0-10.0, pigment 5,0-30,0, ammonium persulfate 5,0-15,0, water - other (see RF patent 2084429 class IPC604 In 41/47, 32 In 27/08, prior. 28.07.94, op. 20.07.96).

This solution is taken as the prototype for both variants of the present invention.

Known composition for protective and decorative coatings in the construction material has the following disadvantages: limited color gamut coatings, because the specified composition allows to obtain only the dark color (black, dark green, etc.,); moreover, obtaining a solid, sustainable coatings is possible only with a high content of tetraethoxysilane, which is toxic, expensive and scarce.

The present invention is based on a solution of the composition for protective and decorative coatings for building materials, which would make it possible to obtain coatings having a wide range of colors, including white and all the bright colors and shades; and would to get a hard, resistant to weathering, durable, heat-resistant coating, curing in a wide real range of temperatures from the minĨeta, the composition for protective and decorative coatings for building materials in the first embodiment of the invention, include polymethylphenyl siloxane lacquer, toluene, silicate, a metal oxide, further comprises organopolysiloxane paint and talc, in the following ratio, wt.%: organopolysiloxane lacquer calculated on dry substance 14,0-20,0, polymethylphenyl siloxane lacquer calculated on dry substance 20,0-22,5, the metal oxide 5,5-15,5, silicate 22,0-23,0, talc 22.5 to 28, toluene - rest.

Composition for a protective and decorative coating on the construction material according to the second variant of the invention, include polymethylphenyl siloxane lacquer, toluene, silicate, a metal oxide, tetrabutoxide, further comprises organopolysiloxane paint and talc, in the following ratio, wt. %: organopolysiloxane lacquer calculated on dry substance 14,0-20,0, polymethylphenyl siloxane lacquer calculated on dry substance 20,0-22,5, the metal oxide 5,5-15,5, silicate 22,0-23,0, talc 22.5 to 28, tetrabutoxide of 0.2-0.3, toluene - rest.

The applicant has not identified technical solutions that are identical to the claimed invention both versions, which allows to make a conclusion about its compliance with the criterion of "novelty".

Rea is roccanova and polymethylphenylsiloxane varnishes, in the claimed ratio of components, gives the resulting coating hardness, strength, good insulation properties and allows you to get an inexpensive coverage that has a wide color gamut, curing in a wide real temperature range from minus 20oTo + 30oWith, including at room temperature, without the use of expensive and toxic initiator of polymerization.

Thanks to the implementation of signs according to the second variant of the invention may provide hard, strong, durable, heat resistant coatings, curing in a wide real temperature range from minus 20oTo + 30oWith, including at room temperature, using minor amounts of expensive and toxic tetraethoxysilane introduced in the manufacture of a composition as a polymerization initiator.

The applicant has not found any sources of information containing data about the impact of an alleged distinguishing signs on achieved as a result of their implementation of the technical result. This, according to the applicant demonstrates compliance with this technical solution, the criterion of "inventive step".

The first component of the composition polyorganosiloxane. It can be introduced into the composition in the form of a varnish KO-915", produced by JSC "silane", , Duncan, Lipetsk region, or the Lac CO-916", produced by JSC "Khimprom", Novocheboksarsk. When using this component in a quantity less of 14.0 wt.% the coating becomes brittle, there is a significant decrease in tensile impact, and the use of excessive quantities, i.e., more than 20 wt.%, complicated the process of curing the coating to cure the coating required drying at high temperature (>60oC) or the introduction of a large number of polymerization initiator.

The role of the film-forming component performs and also the second component of the composition of polymethylphenyl siloxane lacquer, which is included in the composition in an amount of 20.0-22.5 wt.%. As it can be used varnish KO-815", produced by JSC "silane", , Duncan, Lipetsk region or varnish KO-75" manufactured by JSC "Khimprom", Novocheboksarsk. The introduction of this component in the amount of less than 20.0 wt.% complicated the process of curing the coating to cure the coating required drying at high temperature (>60oC) or the introduction of a large number of polymerization initiator, and at its introduction more than 22.5 wt.% parry, and simultaneously pigment, performs the third component of the composition of the metal oxide included in the composition in the amount of 5.5-15.5 wt.%. As the metal oxide, in particular, can be used: titanium dioxide (TiO2), giving the floor white, red iron oxide (Fe2About3- from yellow-red to brown, manganese oxide (MnO2) - black, chromium oxide (CR2About3) - green color, etc. of the introduction of this component in the amount of less than 5.5 wt.% deteriorating the strength of the film, as well as the color of the coating, and the introduction of it in the amount of more than 15.5 wt.% it is not economically feasible due to high cost of metal oxides.

The fourth component of the composition of the silicate included in the composition in an amount of 22.0-23,0 wt.%, acts as a filler, which increases the resistance of the coating. As the silicate can be used aluminosilicate, in particular ground mica. With the introduction of silicate in amounts less of 22.0 wt. % deteriorates the heat resistance of the coating; and at its introduction more than 23,0% by weight composition becomes viscous, poorly plotted on covered items.

The fifth component of the composition talc included in the composition in the amount of 22.5 to 28.0 in wt.%, the.% the composition has a liquid consistency, deteriorates such property as hiding; and the introduction of it in more of 28.0 wt.% composition becomes viscous, poorly plotted on covered items.

The next component of the composition toluene, supplementing the composition to 100 wt.%, acts as a diluent, regulating the viscosity of the composition.

The composition according to the second variant of the invention, comprises another component tetrabutoxide that when unstable chemical composition of varnishes it is expedient to introduce into the composition in a small amount, 0.2 to 0.3 wt. %, as an initiator of polymerization (curing agent). With the introduction of tetraethoxysilane in the amount of less than 0.2 wt.% deteriorating the strength and adhesion of the coating; and the introduction of it in the amount of more than 0.3 wt.% it is impractical, because it is expensive and toxic, in addition, tetrabutoxide (with its high content may cause gelatinization of the composition.
