| 摘 要： | 通过有机单体原位聚合包覆的CaCO3与PP熔融混合制备了PP／CaCO3纳米复合材料，经过正交实验研究了填料饱覆聚合物比、接枝聚丙烯以及复合填料含量对PP缺口冲击强度的影响，结果表明：复合纳米CaCO3只需填加5％就可以将缺口冲击强度提高为原树脂的2倍左右。

| Abstract: | PP/CaCO 3 nanocomposites were prepared with calcium carbonate encapsulated by in-situ polymerized organic monomers by melt mixing process.The effect of the ratio of filler/encapsulating polymer,the contents of grafting PP and fillers on the Izod impact strength of PP were studied by cross experiments.The result showed that the Izod impact strength of the composite increased to two times that of raw PP with 5 % nanoparticle calcium carbonate encapsulated polymer. |
