无机增韧高抗冲PVC树脂的研究

Study on inorganic-toughened high impact PVC resins

主要研究了纳米碳酸钙对高抗冲PVC树脂性能的影响。结果表明:在加入15份纳米碳酸钙时,纳米碳酸钙/高抗冲PVC复合材料的冲击强度可达63.21 kJ/m2,是普通PVC树脂的15倍,是高抗冲PVC树脂的4倍,极大地增强了PVC的韧性。

The effects of nano calcium carbonate on the properties of high impact PVC resins were mainly studied. The results showed that： when adding 15 parts of nano calcium carbonate, the impact strength of nano calcium carbonate/high impact PVC composites could reach 63.21 kJ/m2 , which was 15 times that of ordinary PVC resim, and 4 times that of high impact PVC resins. The toughness of PVC was greatly enhanced.
