水滑石在PVC热稳定剂中的应用

摘要

介绍了欧洲对聚氯乙烯（PVC）中重金属的法规及限制、日本PVC产量的发展情况和水滑石对PVC的稳性机理及其物性。并比较了各类含重金属与不合重金属的热稳定剂的静态热稳定性和我国市场上各种水滑石的静态热稳定性。%The laws and regulations for PVC in Europa, the development of production capacity and out- put of Japan, physic properties were introduced. The stabilities of different heat stabilizers which contained and does not contained heavy metals were compared, and the static stabilities of some hydrotalcites in China market were also compared.
