[0021] A pressure-resistant polyethylene pipe and its preparation method. The preparation method is as follows: first, mix dimethyl tin and dioctyl tin at a mixing ratio of 11:9 (by mass ratio) to obtain a heat stabilizer. Then mix ABS, SBS and EVA at a mixing ratio of 13:7:19 (by mass ratio) to obtain a toughening agent. Then put 120 parts of high-density polyethylene, 2.5 parts of heat stabilizer, 17 parts of toughening agent, 6 parts of stearic acid, 5 parts of paraffin, and 11 parts of active calcium carbonate into the mixer in turn, stirring time: 25min, stirring speed: 660r / min. Put the stirred mixture into a twin-screw extruder for blending and granulation. The temperature range of each section of the extruder is: 160°C. Finally, the granulated granules are extruded into finished pipes through a single-screw extruder. The temperature of the barrel of the single-screw extruder is 180°C, the temperature of the mold is 190°C, and the temperature of the die mouth is 165°C....
