摘　　要：以均匀沉淀法制备锡酸锌包覆纳米碳酸钙粉体（ZSCC）并将其应用到PVC中。通过XPS和TEM研究表明：锡酸锌对纳米碳酸钙进行了较好的包覆，包覆产物的粒径在40～60nm之间；添加ZSCC处理的PVC的LOI和SDR都得到了明显的改善；同时纳米材料的加入对PVC的力学拉伸性能也产生了有利的影响。ZSCC was synthesized by homogeneous precipitation method and it was applied into PVC. TEM and XPS results showed that zinc stannate was coated on nano-CaCO3 surface and the size of proeluct was about 40 - 60 nm. The PVC treated with ZSCC had a higher LOI and lower SDR, and the tensile property was improved a little.
