摘要
本文介绍了无铅化稳定剂的应用现状,重点介绍了无铅化稀土复合稳定剂的作用特性及在UPVC制品中的应用,对稀土化合物的稳定机理进行了探讨。研究表明WWP稀土/钙/锌复合稳定剂无毒、高效、多功能,属新一代绿色环保产品,是具有中国特色的值得大力发展的PVC无铅化热稳定剂。
Current research and application situation of lead-free stabih＇zer was introduced in briefly, while the characteristics, performance, as well as the stable mechanism of rare earth complex stabilizers used in UPVC products were investigated in detail. The examination reveled that the compound stabilizers （WWP） consisted of rare earth complex/calcium salt/ zinc complex are a novel series of high efficient, nontoxic and multi-functional ＂ green＂ stabilizers.
