NOVELTY - Electrically conductive nylon composite material comprises 82-90 wt.% of polyamide 1212, 1-5 wt.% of graphene, 0.1-1 wt.% of antioxidant, 0.5-1 wt.% of coupling agent, 8-13 wt.% of toughening agent, and 0.5-1 wt.% of silicone oil. USE - Electrically conductive nylon composite material. ADVANTAGE - The electrically conductive nylon composite material can be simply prepared with good toughness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing composite material comprising mixing the polyamide 1212 and silicon oil in a mixer for 3-7 minutes to obtain mixed materials and then adding into coupling agent, toughening agent, antioxidant and graphene to mix for 3-7 minutes, extruding the mixed raw material in a double-screw extruder at first section temperature of 180-220 degrees C, a second section temperature of 180-220 degrees C, a third section temperature of 180-220 degrees C, a fourth section temperature of 180-220 degrees C for 1-2 minutes and then melting and pelleting.
