NOVELTY - A polyethylene material comprises high density polyethylene, base resin, composite stabilizer, crosslinking agent, curing agent, composite additive, graphene modifier, plasticizer, composite elastic material, pentaerythritol stearate and polyethylene wax. USE - Polyethylene material used for preparing pipe (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the polyethylene material, which involves adding base resin, curing agent, composite additive, graphene modifier, plasticizer, composite elastic material, polyethylene wax and composite stabilizer into 20-30% high density polyethylene, stirring in a high-speed mixer at 120-130 degrees C 1500-2000 rpm for 25-35 minutes to obtain mixture (A), adding remaining composite stabilizer, pentaerythritol stearate and cross-linking agent into 60-70% mixture (A), mixing in a high-speed mixer at 100-110 degrees C for 10-15 minutes to obtain mixture (B), adding remaining cross-linking agent into mixture (B), mixing at 135-145 degrees C for 18-22 minutes, and extruding and granulating at 160-170 degrees C.
