摘要
研究了环氧大豆油对软聚氯乙烯(PVC)性能的影响。实验表明,铅盐和有机锡的热稳定性较好,单独使用硬脂酸钙、硬脂酸锌、环氧大豆油或不足量的有机锡热稳定剂时,PVC样品很快变色。环氧大豆油与硬脂酸钙、硬脂酸锌、有机锡热稳定剂并用时,环氧大豆油具有很好的协同效应;但环氧大豆油和硬脂酸钙、硬脂酸锌不能简单替代有机锡稳定剂。热重分析证明了不同热稳定剂的效果。作为辅助增塑剂,环氧大豆油用量应低于5份。
The influence of epoxidized soybean oil on the properties PVC was studied. The result was showed that lead salt and organic tin compound had better thermal stability. When zinc stearate, calcium sterate, epoxidized soybean oil or insufficient organic tin compound used separately, PVC specimens changed color quickly. The synergistic effect of epoxidized soybean oil with zinc stearate, calcium sterate or insufficient organic tin compound was obvious, but epoxidized soybean oil and zinc stearate, calcium sterate cannot substitute organic tin compound simply. The effect of different heat stabilizers was demonstrated by thermogravimetry curve. The dosage of epoxidized soybean oil, as a co-plasticizer, should not be excess five phr.
