▎ 摘　　要

NOVELTY - Conductive plastic comprises 60-90 wt.% resin, 1-20 wt.% graphene, 5-20 wt.% flame retardant, 1-10 wt.% dispersing agent, 0.5-5 wt.% antioxidant, 0.1-5 wt.% coupling agent and 1-10 wt.% additives. The additive comprises magnesia, alumina and silicon carbide. USE - Conductive plastic. ADVANTAGE - The conductive plastic has high thermal conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing conductive plastic, which involves: (A) feeding resin into twin screw extruder barrel; (B) mixing graphene, dispersing agents, antioxidants, coupling agents and additive to obtain mixture; (C) adding the obtained mixture in barrel of twin screw extruder; (D) adding the twin screw extruder with magnesium oxide, aluminum oxide, silicon carbide and flame retardants to obtain mixture; and (E) granulating the mixture to obtain conductive plastic.
