PVC-M pipe with excellent wear resistance

The invention provides a PVC-M pipe with excellent wear resistance. The PVC-M pipe is prepared from the following raw materials in parts by weight: 100 parts of PVC resin, 2.5-3 parts of a heat stabilizer, 10-12 parts of an impact modifier, 2-5 parts of a lubricant, 8-12 parts of a wear-resistant modifier and 2-3 parts of superfine active calcium carbonate. The wear-resistant modifier is a silicon gas-phase dioxide or a high-hardness silicate mineral substance with a flaky jade structure or a mixture of the silicon gas-phase dioxide and the high-hardness silicate mineral substance, so that the interfacial compatibility with PVC molecules can be well enhanced, and the wear resistance of the PVC-M pipe is greatly improved. 本发明提供一种耐磨性能优异的PVC-M管材，原料配比为PVC树脂100份、热稳定剂2.5-3份、抗冲改性剂10-12份、润滑剂2-5份、耐磨改性剂8-12份、超细活性碳酸钙2-3份；耐磨改性剂为硅的气相二氧化物或者具有片状玉石结构的高硬度硅酸盐矿物质、或二者的混合物，可以很好地增强与PVC分子的界面相容性，从而大大提高PVC-M管材的耐磨性能。
