摘　　要：采用硅烷偶联剂KH-570对纳米碳酸钙进行表面处理,然后通过熔融共混法制备聚氯乙烯/纳米碳酸钙(PVC/nano-CaCO3)复合材料,用透射电镜观察了nano-CaCO3粒子在PVC基体中的分散状况。随着nano-CaCO3用量的加大,复合材料的冲击强度和失重残余量都有所提高,热分解温度变化不大,玻璃化转变温度先下降然后又有所增加。Using silane coupling agent KH-570 to have surface treatment on nano-CaCO3, prepared PVC/ nano-CaCO3 composite by melt blending, and then obversed the distribution of nano-CaCO3 particles in PVC base by TEM. The impact strength and thermogravimetric residue of the composite increase, the thermal decomposition temperature doesn＇t change too much, and the glass transition temperature decreases at first and then increases with the increase of nano- CaCO3 content.
