摘　　要：介绍了无毒低发泡UPVC发泡体系的分解特性,研究了稀土稳定剂及有机酸对发泡体系、加工流变行为的影响。结果表明,稀土稳定剂的加入使复合发泡剂的分解趋向高温、分解速率降低,同时促进塑化,有利于低发泡UPVC的加工。The decomposition characteristics of non-toxic low-foamed UPVC were analyzed and the influences of rare-earth stabilizer and organic acid on the foaming system and processing rheological behavior are introduced. The result showed the use of rare-earth stabilizer made the decomposition temperature of the composite risen, decrease the decomposition rate and accelerated the plastification of the composite, being of benefit to the processing of low-foamed UPVC.
