| 摘 要： | 用HAAKE流变仪研究了氧化镁／氧化锌稳定体系对聚氯乙烯的动态热稳定性能。结果发现，在氧化镁／氧化锌质量比为2／3的条件下，配合环氧大豆油、硬脂酸钙、无毒亚磷酸酯和有机稳定剂作为辅助稳定剂，其初期着色和热稳定效果都超过了市售钙锌稳定体系，流变性能和动态热稳定特性接近铅盐稳定体系。用这种稳定体系稳定的PVC的力学性能与市售钙锌稳定体系稳定的相当。

| Abstract: | The dynamic thermal stabilizing effect of magnesium oxide/zinc oxide mixture on PVC was studied with HAAKE Rheometer. The results sh owed that when the mass ratio of magnesium oxide/zinc oxide was 2/3, aided w ith EBSO, calcium stearate, phosphite ester and organic stabilizer, a better sta bilizing effect on PVC was exhibited than a commercial calcium/zinc stabilizer, which can be compared with the lead stabilizing system. The mechanical propertie s of PVC containing the new stabilizing system were similar to those using the c ommercial calcium/zinc stabilizers. |
