Description

The invention relates to the field of production and use of heat-resistant adhesives based on carborane-containing compounds. A glue is known that contains carboranphthalocyanine polymer and aromatic isioiianate 11. It maintains at 300 ° C up to 80% of its adhesion strength, but requires the use of solvents (for application) at temperatures up to 300 ° C for curing. The technical essence and the obtained effect of the invention are the closest adhesives5 containing carboradioepoxide, an aromatic diamine and a filler 2. It is applicable without a solvent, but does not have high adhesion strengths and thermal stability when curing below 300 ° C. The aim of the invention is to increase the thermal stability during curing not more than 200 ° C. This is achieved by the fact that the glue, including the carborane-containing product, the modifier and the filler, as a modifier contains an aliphatic, organo-organic, carbo or heterocyclic compound with two or more functional groups selected from the series HE, NHj, SH, NCO, NSO, NCS, and in addition, the modifier and / or carborane-containing product contains an ethinyl group and / or nitrile group in the following ratio of components, parts by weight. Carboran-containing. . Product 100 Modifier 2-5000 Filler 0.1-5000 The modifier is a monomeric or oligomeric compound or a mixture of two compounds. A carborane-containing product may have different functional groups (hydroxyl, carboxyl, amine, haloaliphatic, urinary, benzimidazole, intermediate, thionyl) or not at all. In the quality of the carborane-containing product, carborane-containing polyethers and polyethers, polyamides, polyfeiylene, poly-ichride, polystyrene silane and polyurea can be used.
