摘　　要：合成了一种新型的PVC热稳定剂——氰脲酸锌,通过静态烘箱热老化实验和刚果红实验测定了氰尿酸锌及其复合热稳定剂对PVC热稳定性的影响。结果表明,氰尿酸锌单独作为热稳定剂会出现"锌烧"现象,而复合热稳定剂可以使PVC拥有更好的热稳定效果。A new kind of poly （vinyl chloride） （PVC） thermal stabilizer was prepared by co-precipitation method. The effect of zinc cyanurate and its composite heat stabilizer on the thermal stability of PVC was determined by static oven aging test and Congo red test. The results showed that zinc cyanurate alone as a heat stabilizer will appear＂ zinc burn＂ phenomenon and the compound heat stabilizer can make the PVC have better thermal stability.
