▎ 摘　　要

NOVELTY - Preparing wear-resistant polymer composite material comprises (1) weighing 70-99.7 pts. wt. polymer resin, 0.3-30 pts. wt. solid lubricant, 0.03-3 pts. wt. coupling agent, and uniformly mixing to obtain a mixed material, (2) extruding and granulating the mixed material through a twin-screw extruder to obtain mixed granules, and drying the mixed granules, (3) extruding the mixed granules through a multi-stage stretching extrusion device to obtain a wear-resistant polymer composite material. USE - The wear-resistant polymer composite material is useful in preparing wear-resistant parts e.g. gear, a bearing, and a slide rail (claimed). ADVANTAGE - The method is useful for preparing wear-resistant polymer composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for wear-resistant polymer composite material prepared by above method.
