▎ 摘　　要

NOVELTY - High thermal conductivity graphene modified nylon composite material comprises 40-90 pts. wt. nylon resin, 7.5-48 pts. wt. graphene oxide, 0.5-3 pts. wt. compatibility agent, 2.5-12 pts. wt. surface modified thermal filler, 5-20 parts pts. wt. reinforced fiber, 5-20 pts. wt. flame retardant, 0.1-0.5 pts. wt. antioxidants, 0.1-0.6 pts. wt. lubricant, where compatibilizer is an isocyanate of the isocyanate having functional group imore than 2. USE - High thermal conductivity graphene modified nylon composite material. ADVANTAGE - The high thermal conductivity graphene modified nylon composite material has improves compatibility in the nylon resin matrix, and improves the heat conducting effect of the resin matrix. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing ahigh thermal conductivity graphene modified nylon composite material, which involves: (A) weighing 7.5-48 pts. wt. graphene oxide and 0.5-3 pts. wt. compatibilizer in a high-mixing machine, mixing at room temperature for 10-30 minutes; (B) weigh 40-90 pts. wt. nylon resin, adding 2.5-12 pts. wt. surface-modified heat-conductive filler to the high-mixer, mixing at room temperature for 5-20 minutes; (C) weighing 5-20 pts. wt. reinforcing fiber, 5-20 pts. wt. flame retardant, 0.1-0.5 pts. wt. antioxidant, 0.1-0.6 pts. wt. lubricant in the high-mixer, mixing at room temperature for 5-10 minutes; and (D) adding uniformly mixed material into a twin-screw extruder, melt-blending at 200-290 degrees C and a screw speed of 250-350 rpm, extruding, pulling, cooling, pelletizing, and drying to obtain final product.
