The inner layer is a polyethylene pressure-resistant layer comprising 94.5-95.5 pts. wt. polyethylene resin and 4.5-5.5 pts. wt. graphene reinforced masterbatch. The core layer is a compatible layer comprising 100-110 pts. wt. polyethylene graft resin. The outer layer is a reinforced wear-resistant layer comprising 94.5-95.5 pts. wt. ultra-high molecular polyethylene, and 4.5-5.5 pts. wt. graphene reinforced masterbatch. USE - Used as enhanced wear-resistant polyethylene drainage pipe. ADVANTAGE - The pipe has good flexural modulus, abrasion resistance, improves the wear resistance of drainage pipes and the ability of pipes to resist external pressure according to GB/T198102005, and the tensile strength of 2630MPa, and amplification of 30-50%. DETAILED DESCRIPTION - Enhanced wear-resistant polyethylene drainage pipe, comprises an inner layer (100), a core layer (200), and an outer layer (300) arranged in sequence from the inside to the outside. The inner layer is a polyethylene pressure-resistant layer comprising 94.5-95.5 pts. wt. polyethylene resin and 4.5-5.5 pts. wt. graphene reinforced masterbatch. The core layer is a compatible layer comprising 100-110 pts. wt. polyethylene graft resin. The outer layer is a reinforced wear-resistant layer comprising 94.5-95.5 pts. wt. ultra-high molecular polyethylene, and 4.5-5.5 pts. wt. graphene reinforced masterbatch. The reinforced wear-resistant PE drainage pipe is prepared by (i) mixing polyethylene resin and graphene-enhanced masterbatch in a mixer, and stirring evenly at 100-200 revolutions/minutes to obtain mixture A, adding ultra-high molecular weight polyethylene and graphene-enhanced masterbatch into the mixer, stirring evenly at 100-200 revolutions/minute to obtain mixture B, (ii) adding mixture A, polyethylene graft resin, and mixture B into a three-layer co-extrusion mold to perform co-extrusion outer layer treatment, and compound extrusion molding at a temperature of 190-220 degrees C to obtain enhanced wear-resistant polyethylene drainage pipe, and (iii) opening the operating door of the cooling device, removing the second fixing seat of the clamping mechanism, and sleeve the reinforced wear-resistant polyethylene drain pipe into the clamping mechanism, installing the second fixing seat, closing the operating door, starting the air cooler, blowing cold air into the operation chamber through the air outlet, and at the same time, the cold air passes through the second branch pipe, blowing into the cold air passage, and blowing out from the ventilation hole, cooling the reinforced wear-resistant polyethylene drainage pipe at the same time inside and outside, starting the first motor to drive the rotating gear to rotate, and the rotating gear to drive the rotating table to rotate, cooling the reinforced wear-resistant polyethylene drain pipe, opening the operating door, removing the second fixing seat, taking out the cooled reinforced wear-resistant polyethylene drain pipe, and collecting. An INDEPENDENT CLAIM is also included for preparing the enhanced wear-resistant polyethylene drainage pipe as mentioned above. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of enhanced wear-resistant polyethylene drainage pipe. Inner layer (100) Core layer (200) Outer layer (300)
