DETAILED DESCRIPTION - A high performance polyacrylate composite material comprises 77.8-84.7 %mass polyacrylate, 7-11 %mass chitosan/viscose fiber, 6-8 %mass graphene, 0.5-0.8 %mass 2,6-di-tert-butyl-4-methylphenol, 0.2-0.3 %mass flame retardant, and 1.6-2.1 %mass antistatic agent. The flame retardant comprises polysiloxane and triphenyl phosphate according to mass ratio of (5-9):1. The antistatic agent comprises polyoxyethylene stearate and fatty alcohol polyether amide according to mass ratio of (1.5-2.2):1. The chitosan/viscose fiber is prepared by mixing chitosan and viscose fiber according to mass ratio of 1:(24-28) to obtain mixture, placing the mixture in 7-8 times of ethanol solution containing 58-62 wt.% limonene, heating at 68-75 degrees C, maintaining the temperature for 30-35 minutes, filtering to obtain filter residue, washing with deionized water, drying, and grinding into powder. INDEPENDENT CLAIMS are included for the following: (1) preparation method of high performance polyacrylate composite material, which involves weighing each component, adding to a high-speed mixer, completely mixing to obtain compound, adding the compound to a twin-screw extruder, extruding and granulating at 248-260 degrees C, and molding in an injection molding machine at 248-260 degrees C; and (2) use of high performance polyacrylate composite material in preparation of automotive interior trim material.
