摘要
按照聚氯乙烯(PVC)排水管(PVC-U)通用配方,研究了自制羊毛酸钙锌和羊毛酸镧锌复合稳定剂,对PVC-U性能的影响。测试结果表明,镧锌体系的热稳定效果与复合铅盐相近,但是加工性优于复合铅盐。镧锌体系的拉伸强度、断裂伸长率和维卡软化温度分别为47.25MPa、33.17%、83.50℃,效果优于钙锌体系和复合铅盐。通过扫描电镜(SEM)对材料的断面进行观察,镧锌体系对CaCO3的偶联作用效果优异。
The synergistic stabilization effect of different metal lanolin fatty acids as natural-based thermal stabilizers for poly（vinyl chloride）（PVC） including calcium lanolin fatty acid（Calan2）,zinc lanolin fatty acid（Znlan2） and lanthanum lanolin fatty acid（Lalan3） were studied.The results show that Lan/Zn,Ca/Zn and lead salt have the similar thermal stability,but the rheological properties of Lan/Zn is best.The tensile strength,tensile strain at break and Vicat softening temperature are 47.25 MPa,33.17% and 83.50 ℃ respctively when Lan/Zn is added,which is better than those of Ca/Zn and lead salt.Lan/Zn has excellent coupling effect through material sections observation.
