NOVELTY - Preparing ultra-high wear-resistant graphene epoxy resin composite material involves adding curing accelerator to the epoxy resin solution in a mass ratio of 1:1000-5:1000, and then placing at 70-90 degrees C under stirring for 6-10 hours to obtain mixed solution A. The curing agent is added to the mixed solution A to obtain mixed solution B. The graphene powder is added to the mixed solution B to obtain a mixed solution C. The mixed solution C is poured into the mold and placed in a vacuum at 45-70 degrees C for degassing to remove bubbles for 2-6 hours. The mixed solution C is placed at 110-145 degrees C for 2-4 hours to a soft gel state under normal pressure, and then placed at 145-180 degrees C for 10-16 hours to obtain ultra-high wear-resistant graphene epoxy resin composite material. The graphene powder is a mixture of graphene, graphene oxide, and reduced graphene oxide powder. USE - Method for preparing ultra-high wear-resistant graphene epoxy resin composite material. ADVANTAGE - The method prepares the ultra-high wear-resistant graphene epoxy resin composite material in a simple, cost-effective and eco-friendly manner with improved friction and wear performance.

The graphene powder is a mixture of graphene, graphene oxide, and reduced graphene oxide powder. The epoxy resin is a mixture of bisphenol A type epoxy resin, bisphenol F type epoxy resin, polyphenol type glycidyl ether epoxy resin, and glycidyl ester type epoxy resin. The curing agent is a heating curing type acid anhydride curing agent. The curing accelerator is a mixture of tertiary amines and their derivatives, quaternary ammonium salts, and metal acetylacetone salts.
