INFLUENCE OF THE COPPER(II) HEXAFLUOROSILICATE ONTO THERMAL-OXIDATIVE STABILITY OF THE SELF-EXTINGUISHING EPOXY-AMINE COMPOSITES

Abstract

New elaborated fire retardant-hardener for the epoxy-amine composites on the base of the polyethylenepolyamine and copper(II) hexafluorosilicate has been reported in the article. The influence of the copper(II) hexafluorosilicate onto the thermal-oxidative degradation process of the epoxy-amine composites has been studied. The observed increasing the thermal-oxidative stability of the epoxy-amine composites cured by new fire retardant-hardener is caused by the forming the supplementary chemical bonds arising between the polyethylenepolyamine and copper(II) hex-afluorosilicate in the course of structuring the epoxy-amine composite. It is experimentally proved that the epoxy-amine composites modified by the copper(II) hexafluorosilicate are the self- extinguishing polymers.
