摘　　要：比较了3种无机黏土(超细无机黏土A、偶联剂表面改性无机黏土B、实验室自制大分子表面处理剂DF包覆改性无机黏土C)对PVC材料力学性能、微观形貌的影响,重点研究了无机黏土C对PVC材料动态力学性能、耐热性能的影响。结果表明:①适量添加无机黏土可以提高PVC材料的拉伸性能和冲击性能;②无机黏土C/PVC复合材料具有很好的耐热性能;③无机黏土C的填充效果较好。Influences of three kinds of inorganic clay （i. e. ultrafine inorganic clay A, coupling agents modified inorganic clay B, inorganic clay C modified by macromolecular surface treatment a- gent prepared in laboratory） on mechanical properties and morphology of PVC were compared. Influences of inorganic clay C on dynamic mechanical properties and heat resistance of PVC were investigated. The results show that. （1） suitable amounts of inorganic clay can improve the tensile properties and impact properties of PVC material; （2） inorganic clay C/PVC composites have good heat resistance; （3） the adding of inorganic clay C has good effects.
