绿色环保PVC热稳定剂研究进展

Research Progress of Pro-environment Thermal Stabilizers of PVC

介绍了聚氯乙烯(PVC)的结构特征、热老化和热稳定机理,综述了传统稀土类、有机锡类、金属皂类、复合水滑石类等热稳定剂的研究成果,同时对新出现的一些新型绿色环保PVC热稳定剂,特别是对脲衍生物类、金属醇盐类热稳定剂的研究进展进行了论述,这类新型绿色环保的PVC热稳定剂是未来发展的重要方向。

The structural characteristics,thermal aging and thermal stability mechanism of poly（vinyl chloride） （PVC） were described. The research about traditional rare-earth, organic-tin, metal soap and compound hydrotalcite thermal stabilizer were intro-duced. Meanwhile, the some new green PVC thermal stabilizer, specially urea derivatives and metal alkoxides thermal stabilizers,were summarized, this new green PVC thermal stabilizer become an important direction for future.
