摘要
通过新型低铅、无铅低锡和无铅无锡热稳定剂分别与亚磷酸酯、环氧大豆油、β?二酮、季戊四醇和水滑石进行复配,进行了聚氯乙烯(PVC)的静态和动态热稳定性实验。结果表明:环氧大豆油作为辅助热稳定剂时,与各种主稳定剂的协效作用最好;β?二酮在抑制初期着色方面表现优异;以无铅无锡型为主稳定剂、水滑石为辅助稳定剂时,硬质PVC的热稳定性能有很大提高,因而有着很大的发展潜力。
The polyvinyl chloride （PVC） static and dynamic experiments of the heat stability by three novel low-lead, non-lead and low-tin, and non-lead and non-tin thermal stabilizers remixed respectively with phosphite ester, epoxidized soybean oil, β-diketone, pentaerythritol and houghite were reviewed. The resuits showed the synergistic effect was the best when epoxidized soybean oil was used as auxiliary heat stabilizer; β-diketone could restrain the early coloring up effectively; when non-lead and non-tin thermal stabilizers were used as main stabilizer, and houghite as auxiliary heat stabilizer, the stability of rigid PVC was im- proved perfectly, which showed great potentialities in its development.
