摘　　要：运用刚果红试纸法和热烘箱老化实验法,对硬质PVC(聚氯乙烯)用钙锌复合稳定剂的主要组分如硬脂酸钙、硬脂酸锌、多元醇、环氧大豆油、亚磷酸酯以及稳定性助剂等进行了考察,得到了各组分及各组分用量之间协同作用的关系,同时还得到了硬质PVC用钙锌复合热稳定剂的实用配方。The main components of Ca-Zn composite thermal stabilizes and other stabilizers in rigid PVC were investigated by Gongo red and heating aging methods. The relation of synergistic effect between component and the amount of component, the formula of Ca-Zn composite thermal stabilizer in rigid PVC were obtained.
