EN 2182582, 7 C09D 183/04, C09D 5/08, 2001.09.10.

The task, which is aimed by the invention, is to increase the effectiveness of protective coatings on the basis of the claimed composition in operating conditions, due to the improvement of physico-mechanical properties of the coating and give him the insulating properties, the expansion of the means of this assignment.

The technical result is:

- improvement of physico-mechanical properties of coatings;

The mixture is stirred until a homogeneous mass. In the second reactor load estimated number of organopolysiloxane resin, pentaftalevyh lacquer, remaining solvent, filler and pigments. The contents of the second reactor was dispersed for 3 hours. Then the mass of the first reactor is pumped into the second reactor and stirred for 3 hours.

as pentaftalevyh lacquer Varnish PF-053 THE 2311-001-589-484-36-2003.

To obtain compositions of different colors as heat-resistant pigments used aluminum powder GOST 5494-95, various heat-resistant pigments, such as pigment black heat - THE 2364-017-00303835-96; or pigment blue (10446 Blu) or pigment green (1084 Green) firm Cerdes Corp. (USA);

as a rheological additive use Benton 34 F. Rheox or other inorganic substances, containing montmorillonite (bentonite clay);

as the solvent used xylene oil (GOST 9410-78), oil solvent THAT 38.101809-90, toluene oil - GOST 14710-78;

the filler used mica with a particle size of not more than 160 mm of GOST 14327-82, GOST 855-74;

as a porous silicate perlite with a particle size of not more than 140 μm - GOST 10832-91; diatomaceous earth - OST 18-169-74.

as a thickener use Panel 20 - FT-138-96-01; Tixosil firm "OMIA" (Germany is).

Panel - organomodified thick, the hydrogenated product of the interaction of magnesium silicate and Quaternary ammonium salts. Chemical formula: SiMg8O30(OH)4(OH2)4·8H2O; CIN26H48/. Physico-chemical characteristics: Color is light cream; the appearance of dry fine powder; Humidity - 11%; bulk density of 250 g/l ±50; Viscosity Brookfield not less than 70000 LP; (25°C, 5 rpm); the Residue on a sieve of 75 μm - <1%;

Comparison of the claimed composition with a known composition allows to make a conclusion about its compliance with the criterion of "Novelty", as in this case contains a new set of components in the new proportions.

The specified limits of the ratios between the components of the composition are determined experimentally and are optimal from the point of view of achieving a positive technical result and minimal cost.

The optimum content pentaftalevyh l the CA in the composition is 8,0-14,0 wt.%. The optimum content of the polymer isobutylacetate is 5-7 wt.%. The reduction in the content of these components in the composition results in coatings with low physical and mechanical properties.

Use them in the specified quantity reduces the amount of organopolysiloxane resin, which contributes to the reduction of the total composition and the improvement of physical and mechanical properties.

In the manufacture of compositions for coatings known application pentaftalevyh varnish together with the organopolysiloxane resins and thermally stable pigments. (A.S. USSR 169614, IPC 09D 183/06, publ. 1991). However, such coatings do not have sufficient heat resistance and have low adhesion. In the inventive compositions proposed a new combination of known components with new components and new quantitative ratio, which led to improved technical result, namely the sedimentation stability of the composition during long-term storage and have a significantly lower rate of sedimentation of particles of pigment and filler in consumable containers when it is applied. The improvement of physical and mechanical properties of the coating, and it is resistant to water, gasoline, oil film strength at impact.

Introduction to the composition of the filler in the form of porous silicate and thickener specified in the amounts not only improves the sedimentation properties due to chemical interaction of the porous structure of the silicate with acrylic binders, but you can reduce the cost of the composition due to the complete or partial replacement of mica. The combination with a heat-resistant pigments and other components in the above amounts enables you to extend the temperature range of operation of the coating and give it insulating properties.

The given amounts of filler and thickener in the composition are optimal. The content of these components above these values contributes to the increased viscosity of the composition, which leads to technological difficulties in obtaining coatings.

Also optimal (11-17 wt.%) is the specified number of pigments. The increase in the content of pigments in the composition leads to a decrease sedimentation stability (observed accelerated sedimentation). The reduction in the content of pigments leads to deteriorating the hiding power of the coating, and also decreases its resistance.

From table 2 it follows that when used as a filler of porous silicate or a mixture of mica with porous silicate thermal conductivity of the material with the coating is 0.01 W/MK, which gives the coating on the basis of the claimed composition insulating properties.

Thus, the claimed composition has a high sedimentation stability during storage, dries faster and provides ant is corrosion coatings with high resistance to water, gasoline and oil, extended temperature range (650°C) coating, and giving the floor insulation properties will allow us to expand the scope of this composition. Moreover, by reducing the value of indicator coverage (see table 2) saving of paint material.
