SYNTHESIS OF HYBRID EPOXYURETHANE COATINGS AND THEIR PHYSICOCHEMICAL CHARACTERISTICS

Аннотация

Processes for the synthesis of an ethoxyurethane oligomer based on the reactions of cyclic propylene carbonate with propylenediamine, which under the influence of silicon compounds is transformed into an organic silicon compound with a urethane group, have been carried out. The obtained ethoxyurethane oligomer and its silicon modification by reactions with a commercial epoxy resin give hybrid epoxy-urethane adducts. The obtained adducts are cured with amines in order to obtain epoxyurethane coatings. The mechanical, physicochemical, thermal and anticorrosion characteristics of the obtained coatings were investigated, as a result of which high indicators of the physicochemical characteristics and corrosion resistance of silicon hybrid coatings were established.
