摘要
研究确定了几种稳定剂间的协同作用和较佳复配结果。研究结果表明:(1)Ca/Zn与环氧大豆油、亚磷酸酯、β-二酮均有较好的协同作用,优化的Ca/Zn稳定剂配方为:Ca/Zn总量2.0份、环氧大豆油5份、13-二酮0.4份、亚磷酸酯0.5份;Ca/Zn、13-二酮、ESO与有机锡有很好的协同效应。
The synergy of several heat stabilizers was researched and the optimum formula was obtained. The experiment results showed that：Ca/Zn had good cooperativity with ESO, β -diketones, phosphite esters. The optimum dosage of Ca/Zn heat stabilizers are Ca/Zn 2. 0 part, ESO 5 part,β - diketones 0. 4 part, phos- phite esters 0. 5 part. And Ca/Zn, β - diketones, ESO had good synergism with organotin.
