摘　　要：介绍了有机锡类、稀土类、钙/锌类及这三种混配等环境友好型热稳定剂应用在聚氯乙烯中的力学性能、稳定时间、黄度指数、热老化烘箱试验及恒温热失重分析等的性能进行了系统的评价。结果表明:有机锡类热稳定剂对PVC的稳定性优于稀土类和钙锌类,三种按一定配比混配后对PVC的稳定性有显著的提高。This paper introduces organotin,rare earth,calcium/zinc and three kinds of mixed environmental friendly heat stabilizers in PVC.Their mechanical properties,stability time,yellowness index,thermal aging oven test and thermogravimetric analysis are systematically evaluated.The results show that the stability of organotin heat stabilizers to PVC is better than that of rare earth and calcium zinc.The stability of PVC is improved significantly when the three heat stabilizers are mixed in a certain proportion.
