摘　　要：考察了两种硅灰石刚性粒子填充硬聚氯乙烯的力学性能。结果表明 ,在一定的填充量范围内 ,两种硅灰石都能提高PVC的冲击强度 ;硅灰石粒子表面包覆了聚甲基丙烯酸甲酯改性处理后 ,对基体树脂的力学性能改善明显 ,尤其是小粒径的改性硅灰石刚性粒子改进更大。另外 ,还结合电子显微镜观察对共混体系的增韧机理进行了讨论。Mechanical properties of two sorts of wollastonite filled poly(vinyl chloride) compounds were studied respectively.The result reveals that within certain range of filling amount,the impact strength of the systems is increased.Once the two wollastonites were coated with polymethylmethacrylate,they can improve the mechanical properties obviously.And the toughening mechanism of the composites was investigated by means of TEM.
