▎ 摘　　要

NOVELTY - A self-extinguishing epoxy resin composition comprises 20-25 wt.% liquid phosphorus flame-retardant, 2-5 wt.% active diluent, 0.1-0.2 wt.% filler, graphene having a diameter of 5-25 mu m, 1-3 wt.% copper nanoparticles and 0.4-0.75 wt.% electroconductive soot. USE - Self-extinguishing epoxy resin composition. ADVANTAGE - The self-extinguishing epoxy resin composition has increased electroconductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the epoxy resin composition, which involves homogenizing 0.5-1.5 wt.% viscosity reducing agent, 0.1-0.5 wt.% silicone-free venting agent, active diluent, liquid phosphorus flame retardant, filler, graphene, copper nanoparticles and electroconductive carbon black.
