▎ 摘　　要

NOVELTY - Flame-retardant graphene electric conduction material comprises 100 pts. wt. polyethylene and ethylene copolymer, 8-14 pts. wt. silicone masterbatch, 10-20 pts. wt. decabromodiphenyl ethane, 5 pts. wt. antimony trioxide, 10-15 pts. wt. graphene and 0.5 pt. wt. antioxidant B-D. USE - Flame-retardant graphene electric conduction material used for cable outer layer structure (claimed), particularly high pressure power transmission cable. ADVANTAGE - The material increases flame retardant property and high pressure output of cable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of flame-retardant graphene electric conduction material comprising stirring raw materials except graphene using low mixing stirrer; pouring in internal mixer; adding graphene and mixing; entering mixture in double cone feeding machine; and pressing, single screw extruding, granulating and cooling.
