THERMAL-OXIDATIVE DEGRADATION OF SELF-EXTINGUISHING EPOXY-AMINE COMPOSITES MODIFIED BY COPPER(II) CARBONATE

Abstract

Based on the structural and chemical analysis of coordination potential of transition metal compounds with amine-hardeners, the prospectivity of using copper(II) carbonate for the combustibility reduction of nitrogen-containing epoxy polymers has been foreseen. Self-extinguishing epoxy-amine composites modified by copper(II) carbonate have been elaborated; their production technology has been described. The influence of the modifier on the thermal-oxidative degradation process of epoxy-amine composites modified by CuCO3 has been studied. It has been ascertained that increasing of the thermal resistance of epoxy-amine composites modified by copper (II) carbonate is realized through the formation of strong coordination bonds which arise between the copper atoms and nitrogen atoms of the amine-hardener.
