NOVELTY - An ultra-high molecular weight polyethylene, graphene and rubber composite material comprises ultra high molecular weight polyethylene, rubber and graphene with the mass ratio of 100:(10-100):(0.055-4), preferably 100:11:0.533. USE - Ultra-high-molecular-weight polyethylene, graphene and rubber composite material (claimed). ADVANTAGE - The lightweight composite material has high toughness and maintains strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method of ultra-high-molecular-weight polyethylene, graphene and rubber composite material, which involves blending ultra high molecular weight polyethylene with graphene, extruding and granulating ultrahigh molecular weight polyethylene, graphene and dispersing aid in the mass ratio of 100:(0.05-2):(0.2-1), blending rubber and graphene under heating conditions using an open mill or an internal mixer, adding dispersing agent, cutting-granulating, where the mass ratio of graphene and dispersing aid is 100:(10-100) and mixing the granules.
