NOVELTY - Polyethylene composite material comprises 50-100 pts. wt. polyethylene, 0.1-1 pts. wt. graphene, 0.1-1 pts. wt. carbon nanotubes, 0.1-1 pts. wt. fullerene, 2-10 pts. wt. maleic anhydride grafted polyethylene, 1-3 pts. wt. antioxidant, 1-3 pts. wt. plasticizer, and 1-2 pts. wt. coupling agent. USE - Polyethylene composite material. ADVANTAGE - The polyethylene composite material is prepared in a simple manner, produced in batch, and obtained by once injection of molding product. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing polyethylene composite material, which involves: (A) mixing graphene, carbon nanotubes and fullerenes under high-speed stirring to obtain mixture; (B) mixing polyethylene with mixture and various auxiliary agents to obtain mixed material; (C) drying the obtained mixed material at 120-140 degrees C for 5-12 hours; and (D) feeding dry mixed material fed into a twin-screw extruder, and crushing at 150-170 degrees C under stirring speed of 20-45 revolutions/minute to obtain desired product, where feeding speed is 8-12 revolutions/minute and pelletizer speed is 150-190 revolutions/minute.
