摘要
采用热老化烘箱法和电导法研究了一种新型液体钠锌热稳定剂在聚氯乙烯(PVC)中的应用,并进行了热稳定性、力学性能、热分解动力学性能的研究。结果表明,当钠、锌离子质量比(Na/Zn)=1/1时,PVC热稳定时间达到48min,表现出优良的长期热稳定性;添加该热稳定剂的PVC软制品具有优良的力学性能;液体钠锌热稳定剂的加入使PVC的稳定性得到显著增强。
A A highly efficient and low cost novel liquid Na/Zn thermal stabilizer was developed in this work. Its application in poly（vinyl chloride）（PVC） was investigated by heat aging test and conductivity test. In comparison with pure PVC, the thermal stability time of PVC films was extended to 48 min though adding Na/Zn thermal stabilizer at a Na/Zn mass ratio of 1/1. The dynamic thermogravimetric analysis also confirmed that the Na/Zn stabilizer presented an obvious improvement of stability on thermal degradation. Besides, the Na/Zn stabilizer provided soft PVC with excellent mechanical properties.
