▎ 摘  要

NOVELTY - Enhanced wear-resistant material containing graphene enhancer comprises graphene, a polyolefin and a coupling agent, where the weight ratio of graphene to polyolefin is (0.5:99.5)-(10:90), and the amount of the coupling agent is 0.5-5% of the graphene weight. USE - Used as an enhanced wear-resistant material containing graphene enhancer. ADVANTAGE - The method improves abrasion performance and mechanical properties of polyolefin material, and expands the application prospects of the polyolefin material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the enhanced wear-resistant material containing the graphene enhancer, comprising taking graphene, the polyolefin, the coupling agent and a solvent as raw materials, where the weight ratio of graphene to the polyolefin is (0.5:99.5)-(10:90), and the coupling agent is (0.5-5% of the graphene weight), dissolving the coupling agent in the solvent in a container, and then dissolving graphene, performing ultrasonic processing of the mixed materials by dispersing ultrasonically for 30 minutes to 1.5 hours, performing solvent evaporation to obtain constant weight of graphene, the polyolefin and the coupling agent, and then melt-blending the materials in an internal mixture at 190-230 degrees C for 7-20 minutes.
