摘要

It is established that in the presence of mineral additives introduced into an aqueous emulsion of an epoxy oligomer, the process of its oxidative destruction begins at higher temperatures (by 100–200°C) and proceeds significantly more slowly. After the complete combustion of the organic products of thermal decomposition and the thermal transformations of the mineral additives (Portland cement, tetracalcium phosphate, sodium and zinc dihydrophosphates, silicates) at temperatures of 700–800°C, thin films are formed on the surface of the substrates, which are resistant to temperatures of 1000–1200°C.
