A high-speed extrusion anti tracking polyethylene sheath material and its preparation method, the raw materials comprising: 40-60 parts of high-density polyethylene; 10-20 parts of low-density polyethylene; 22-28 parts of anti electric trace additive; 2-3 parts of charcoal black masterbatch; Antioxidant 0.2~0.4 parts; 2-3 parts of lubricant. Preparation method, including: 1. Weigh the material and place it in a mixer, stir at low speed for 3-5 minutes at room temperature, with a speed of 100-120rpm, to obtain the mixture; 2、 Introduce the mixture into the feeding hopper of the twin-screw extruder, melt and extrude it through the twin-screw extruder, cool it down, pelletize it, and dry it to obtain high-speed extruded electric trace resistant polyethylene sheath material; Extrusion temperature is 165-220 ℃. The present invention improves the processing performance of materials, enhances the quality and speed of wire extrusion processes, and thereby increases production capacity.
