摘要
聚氯乙烯(PVC)具有价廉,难燃,耐腐蚀性和透明性好等优点。但其稳定性差,在外界因素如热、光、氧及力的作用下易发生分解和交联反应,致使PVC的加工和使用困难。因此,开发有效的热稳定剂对发展PVC工业具有重要意义。文章介绍了聚氯乙烯(PVC)热稳定剂研究现状,并对聚氯乙烯热稳定剂的应用前景进行了展望。
PVC has the advantage of low-cost, flame retardant, corrosion resistance and transparency. However, it can easily decompose and have cross-linking reaction at the external factors such as heat, light, oxygen and the role of power. The resulted some difficult in PVC producing and using l^rocess. Therefore, it is very significant in developing an effective thermal stabilizer for PVC industrial. The research progress of heat stabilizer for PVC was discussed, and the prospect of heat stabilizer in application were predicted.
