摘要
稀土在聚氯乙烯 (PVC)助剂上显示出了优良的性能 ,本文综述了PVC用稀土助剂 ,特别是稀土热稳定剂的开发、研究进展以及发展前景 ,并讨论了稀土热稳定剂的作用机制。确定稀土化合物是一种可以替代传统稳定剂的新型稳定剂 ,具有广阔的应用前景。
The progress in development and research of rare earth PVC heat stabilizers and processing aids were reviewed. The heat stabilization mechanism of rare earth heat stabilizers was also discussed. It is known that rare earth compounds are new types of heat stabilizers for polyvinyl chloride, which may be used to substitute the conventional heat stabilizers. Therefore, they can be applied widely in the plastics industry in the future.
