摘要
通过对PVC及CPVC的结构进行比较,从结构特点上分析了CPVC不稳定的原因,并从铅盐类、有机锡类、金属皂类、稀土类及有机辅助类热稳定剂几个方面介绍了目前CPVC常用热稳定剂的种类、稳定机理及研究现状;同时对CPVC热稳定剂的发展方向和应用前景进行了展望,指出稀土作为我国特色资源,开发稀土复合热稳定剂具有非常广泛的发展潜能。
By comparing the structures of PVC and CPVC, the reasons for the instability of CPVC are analyzed from the structural characteristics. The types, stabilization mechanism and research status of common heat stabilizers for CPVC are introduced from the aspects of lead salts, organotin, metal soaps, rare earth and organic auxiliary heat stabilizers. At the same time, the development direction and application prospect of CPVC heat stabilizers are prospected. It is pointed out that rare earth, as a characteristic resource in China, has a very wide development potential to develop rare earth composite thermal stabilizers.
