摘要
金属皂类稳定剂中铅皂、锡皂稳定性好,但有毒;钙皂、钡皂初期热稳定性差,锌皂初期热稳定性较好,但持久性差;有机锡类稳定剂热稳定性好,但价格昂贵,且在加工过程中有刺激性气味产生;而稀土类稳定剂作为新型发展起来的无毒热稳定剂,热稳定性和持久性均较好,且无毒、环保、价廉,适应当今PVC制品无毒、无污染、高效的发展要求。文中介绍了稀土热稳定剂的性能特点,功能性以及发展趋势。
The stability of metal soap stabilizer was excellent,but it was possessed the property of toxicity.Ca and Ba stabilizer'early stability was poor,and the Zn stabilizer'early stability was satisfactory,but the persistence was poor.It was summarized the rare earth heat stabilizer's properties and development tendency in this paper.
