摘　　要：一种α晶成核剂和一种β晶成核剂分别被引入到含有大量滑石粉的聚丙烯复合材料中。力学测试、收缩率测试、热分析及X射线衍射结果显示,即使滑石粉大量存在,额外添加少量成核剂仍可对复合材料的刚性、韧性、热变形温度、尺寸稳定性及结晶行为产生影响。两种成核剂皆表现出较高的诱导成核能力,两者带来的效果差异在此也进行了比较。Theαnucleating agent andβnucleating agent were added separately into the composites with a large amount of talc.The results of mechanical properties,shrinking percentages test,thermoanalysis and X-ray diffraction show that the rigidity,toughness,thermal deformation temperature,dimensional stability and crystallization behavior of the composites could still be affected by the addition of small amount of nucleating agent,even if there is large amount of talc.Both of the two nucleating agents show high nucleation induction ability and the difference of effect between them are compared.
