摘要

利用型腔体积可控注塑发泡装备制备聚丙烯/无机纳米粒子微发泡复合材料，通过复合材料的流变行为和结晶行为，分析了无机纳米粒子对聚丙烯发泡行为的影响。结果表明：无机纳米粒子有促进气泡异相成核作用，同时无机纳米粒子引入可以提高聚丙烯黏弹响应和降温结晶起始温度，起到了抑制泡孔结构恶化的作用，显著改善了聚丙烯的泡孔结构；在聚丙烯材料中添加纳米CaCO

、纳米OMMT、纳米SiO

进行发泡，以 PP/OMMT发泡材料的发泡质量最理想，其泡孔密度和尺寸分别为2×10

个/cm

和24. 2µm。

Abstract

The Foamed Polypropylene (PP) and polypropylene/inorganic nanoparticles composites samples were prepared with different kinds of inorganic nanoparticles in the same volume expansion ratio using a injection molding machine equipped with volume-adjustable cavity

and the foaming behavior was investigated. It was found that cell structure of pure Polypropylene was deteriorated

however the introduction of inorganic nanoparticles improved the rheological property and crystallization onset temperature of polymer melt

and the cell structure deterioration was suppressed

and the foaming behavior of Polypropylene composites was excellently improved. The results show that the PP/OMMT foamed composite had the best cell morphological structure. The cell diameter and density were 24. 6um and 2 × 10

cell/ cm3 respectively.
