▎ 摘　　要

NOVELTY - Wear-resistant crosslinkable polyethylene composition comprises high-density polyethylene (I), low-density polyethylene, crosslinking masterbatch, antioxidant and additives. The additive is inorganic filler and/or organic modifier. The inorganic filler is glass flakes, glass fibers, copper oxide, graphene, carbon nanotubes, molybdenum disulfide, and/or quartz powder. The organic modifier is polyoxymethylene, thermoplastic phenolic resin, thermoplastic urea-formaldehyde resin, thermoplastic melamine-formaldehyde resin, polyurethane, PTFE, and/or nylon. USE - The composition is used for preparing a wear-resistant crosslinked polyethylene material (claimed). ADVANTAGE - The composition forms a crosslinkable polyethylene system with excellent high melt strength and abrasion resistance by adding crosslinking masterbatch, antioxidant, inorganic filler and/or organic modifier, so that the prepared material has excellent wear resistance and mechanical properties at the same time. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for preparing a wear-resistant crosslinked polyethylene material, comprising uniformly mixing the above-mentioned components of the composition and placing into a counter-roll extruder for heating and extrusion granulation, and subjecting the obtained granules to crosslinking molding processing to obtain the product; (2) the wear-resistant crosslinked polyethylene material prepared by the method, wherein the wear rate of the material is less than 0.2%, preferably less than 0.13%, the Shore hardness is 90-100 A, preferably 95-100 A, and the impact strength is 20-59 kJ/mm2.
