研究了不同粒径云母、第三组份对PP材料力学性能影响,并用偏光显微镜观察了PP球晶。结果表明:用马来酸酐接技聚丙烯与WD 52偶联剂处理过的填充体系综合性能最优,并使PP球晶细化。
The effects of mica with different particle size and the third component on the mechanical properties of PP were investigated. The spherulites of PP were observed by polarized light microscope. The results show that the filling system treated with maleic anhydride graft polypropylene and WD 52 coupling agent has the best comprehensive properties and refined PP spherulites.
