▎ 摘　　要

NOVELTY - Composite resin material comprises 65-80 pts. wt. first poly(methyl methacrylate) (PMMA) resin, 15-30 pts. wt. acrylonitrile styrene acrylate (ASA) resin, 5-10 pts. wt. compatibilizer, 0.2-0.6 pts. wt. antioxidant, 0.2-0.5 pts. wt. processing auxiliary agent, 1-2 pts. wt. graphene oxide master batch and 0.5-1 pts. wt. black powder raw material. USE - Composite resin material used in preparing an automobile unit (claimed). ADVANTAGE - The composite resin material improves the overall coloring ability of the material by introducing graphene oxide masterbatch, so that the composite resin material has the mirror-bright effect of piano black, and the black-bright effect is better than similar products in the market, improves the manufacturing efficiency of automobile units such as automobile grille while greatly saving the manufacturing cost, which has a broad market application prospect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing composite resin material, which involves taking or preparing graphene oxide master batch; (2) weighing the raw materials, adding into a high speed mixer to mix to obtain the premix, and extruding and granulating the premix compound; and (3) an automobile unit, which is prepared by using the composite resin material, where the automobile component is automobile grid.
