摘　　要：主要介绍了PVC热稳定剂的发展历程,分别对铅盐稳定剂、金属皂类热稳定剂、有机锡稳定剂、钙锌复合热稳定剂四大类热稳定剂进行了详细介绍,并对两类不同配方的钙锌类稳定剂性价比进行了对比。在热稳定剂以无毒、无公害为未来发展的大背景下,我国对PVC产品的全面禁铅的脚步正在加快。就符合国家环保要求的趋势而言,无毒、无污染、复合、高效将是未来热稳定剂的方向发展,尤其4A沸石应用于PVC热稳定剂有巨大潜能。This article mainly introduces the development history of PVC heat stabilizers,and provides a detailed introduction to four major types of heat stabilizers:lead salt stabilizers,metal soap heat stabilizers,organic tin stabilizers,and calcium zinc composite heat stabilizers.Meanwhile,a comparison was made between the cost-effectiveness of two different formulations of calcium zinc stabilizers.Against the backdrop of the future development of non-toxic and pollution-free heat stabilizers,China is accelerating the comprehensive lead ban on PVC products.In terms of meeting the national environmental protection requirements,non-toxic,pollution-free,composite,and efficient will be the direction of future development of heat stabilizers,especially the application of 4A zeolite in PVC heat stabilizers has great potential.
