摘要
以一种简便的方法制备了环氧基保留完好的高纯度环氧脂肪酸钙/锌,并对其热稳定性进行了研究。研究表明,环氧脂肪酸钙/锌对聚氯乙烯(PVC)的热稳定作用类似于硬脂酸钙/锌,但其热稳定效能明显优于后者,环氧脂肪酸钙比硬脂酸钙具有较好的初期着色性,环氧脂肪酸锌较硬脂酸锌具有较长的“锌烧”时间。
High purity calcium/zinc epoxydised fatty acid salt, with preserved epoxy groups completely, is synthesized directly. Heat stabilization of calcium/zinc epoxydised fatty acid salt on poly （vinyl chloride） is similar to calcium/znic stearate and is better than the latter in long-term stability, and have good initial color of PVC, and can be used in nontoxic PVC products with good economic and social effect.
