PVC plastic modified material

The invention discloses a PVC plastic modified material, which is characterized by being prepared from the following raw materials, by weight, 90-100 parts of the PVC, 5-8 parts of zinc oxide, 5-7 parts of white carbon black, 16-20 parts of titanium dioxide, 2-4 parts of silicon carbide and 10-12 parts of calcium carbonate. The material is prepared with addition of the calcium carbonate, the titanium dioxide, the zinc oxide and the like, wherein the titanium dioxide and the zinc oxide improve wear resistance and high-temperature resistance of the PVC while the calcium carbonate can perform toughening modification to the PVC, thereby improving the comprehensive performance of the PVC, and finally saving materials. 本发明公开了种PVC塑料改性材料，其特征在于,由以下重量份数的原料制成：聚氯乙稀90-100份，氧化锌5-8份，白炭黑5-7份，钛白粉16-20份，碳化硅2-4份，碳酸钙10-12份。本发明的有益效果为：本发明通过添加碳酸钙、钛白粉、氧化锌等材料，钛白粉和氧化锌提高PVC的耐磨性和耐高温性，而碳酸钙能对PVC进行增韧改性，从而实现提高达到和改善PVC？综合性能，最终实现能节约材料目的。
