NOVELTY - A reinforced wear-resistant gas pipe comprises inner layer, core layer, and outer layer. The inner layer is prepared from 90-94 pts. wt. polyethylene resin, and 4-7 pts. wt. graphene functional masterbatch. The core layer is prepared from 100-120 pts. wt. polyethylene graft resin. The outer layer is prepared from 90-95 pts. wt. block copolymer polypropylene and 3-6 pts. wt. graphene functional masterbatch. The gas pipe is prepared by adding the raw materials of inner layer, core layer and outer layer into a three-layer co-extrusion mold, performing co-extrusion outer layer treatment, and performing compound extrusion molding. The graphene functional masterbatch is prepared by weighing polyethylene resin, graphene, lubricant, antioxidant and light stabilizer, pre-treating graphene, putting the polyethylene resin, pretreated graphene, lubricant, antioxidant and light stabilizer into the internal mixer, banburying the mixture, and performing extrusion granulation. USE - Gas pipe. DETAILED DESCRIPTION - A reinforced wear-resistant gas pipe comprises inner layer, core layer, and outer layer. The inner layer is prepared from 90-94 pts. wt. polyethylene resin, and 4-7 pts. wt. graphene functional masterbatch. The core layer is prepared from 100-120 pts. wt. polyethylene graft resin. The outer layer is prepared from 90-95 pts. wt. block copolymer polypropylene and 3-6 pts. wt. graphene functional masterbatch. The pipe is prepared by adding the raw materials of the inner layer, core layer and outer layer into a three-layer co-extrusion mold, performing co-extrusion outer layer treatment, and performing compound extrusion molding at a temperature of 190-220 degrees C. The graphene functional masterbatch is prepared by weighing 40-50 pts. wt. polyethylene resin, 85-95 pts. wt. graphene, 2-4 pts. wt. lubricant, 0.5-1.5 pt. wt. antioxidant and 1-2 pts. wt. light stabilizer, pre-treating graphene, putting the polyethylene resin, pretreated graphene, lubricant, antioxidant and light stabilizer into the internal mixer, banburying the mixture at a temperature of 140-165 degrees C for 40-50 minutes, putting the mixture into the granulation equipment, and performing extrusion granulation at a temperature of 180-195 degrees C for 30-40 minutes. An INDEPENDENT CLAIM is included for preparation of the gas pipe.
