摘　　要：通过热稳定性、析出性和力学性能测试,研究了马来酸单酯镧与热稳定剂、润滑剂配合对硬聚氯乙烯(UPVC)型材的性能影响。结果表明,马来酸单酯镧与适量的硬脂酸锌、亚磷酸酯有良好的协同效应,与润滑剂石蜡配合在UPVC中使用时,容易出现析出现象,而与硬脂酸酰胺配合使用时,析出不明显,生产的UPVC型材具有较高的拉伸断裂强度、冲击强度和焊角强度。The（monoester maleic acid） lanthanum,heat stabilizer and lubricant.were used in the heat stabilization for UPVC profile.The stability and separativeness and mechanical properties for the profile were studied.The results showed that there was a good synergistic effect in（monoester maleic acid） lanthanum and zinc stearate and phosphite ester.The（monoester maleic acid） lanthanum can be separated from UPVC when it was used cooperatively with wax and does not separated easy with stearic amide.The tensile strength and impact strength and fillet welding strength for UPVC profile is higher.
