摘　　要：以PE作为载体树脂,加入发泡剂AC、成核剂、包覆体制备出高性能PP用微孔发泡母粒。研究并讨论不同种类的成核剂和包覆体及其加入量对微孔发泡PP材料力学性能的影响。结果表明:成核剂选择超微细滑石粉,包覆体选择EVA时发泡材料的综合力学性能较好。母粒的最佳配方为:AC10%、PE40%、超微细滑石粉30%、EVA20%。Took PE as the carrier resin, joins foaming agent AC, nucleating agent and wrap agent,manufactured high performance foaming masterbatch which used for PP. Studied and discussed the effect of different kind of nucleation agent and wrap agent and joined quality for microcellular foaming PP mechanical properties. The result showed that, nucleating agent choose ultra-fine talc , wrap agent choose EVA can get good properties. The best prescription for masterbatch was AC 10% ,PE 40% ,ultra-fine talc 30% ,EVA 20%.
