新型环保增塑剂环氧脂肪酸甲酯合成研究

摘要：增塑剂是现代塑料工业最大的助剂品种,对促进塑料工业特别是聚氯乙烯工业的发展起着决定性作用。

凡能和树脂均匀混合,混合时不发生化学变化,但能降低物料的玻璃化温度和塑料成型加

工时的熔体黏度,且本身保持不变,或虽起化学变化但能长期保留在塑料制品中并能改变树脂的某些物理性质,具有这些性能的液体有机化合物或低熔点的固体,均称为增塑剂. 增塑剂按其作用方式可以分为两大类型，即内增塑剂和外增塑剂。

研究了环保增塑剂环氧脂肪酸甲酯的合成工艺及影响因素,其影响因素包括甲酸用量、水的用量、反应温度、反应时间等对产物环氧值的影响。研究了以脂肪酸甲酯为原料,合成环氧脂肪酸甲酯的最佳工艺条件。通过实验得到较理想的反应条件为脂肪酸甲酯∶双氧水∶甲酸,反应温度适中,催化剂浓硫 酸,适量稳定剂。

环氧脂肪酸A甲酯在常温下为浅黄色液体,是以脂肪酸甲酯为主要原料的新型环保增塑剂,是一种无毒、无味的聚氯乙烯增塑剂兼稳定剂,它能有效地替代邻苯二甲酸二辛酯(DOP),与聚氯乙烯的相容性好,挥发性低,对光和热有良好的稳定作用,可适用于所有的聚氯乙烯塑料制品,并可改善制品的光、热稳定性。在聚氯乙烯薄膜或人造革加工中使用性能更佳。另外该产品还广泛使用在电线电缆片材、管材,塑料鞋子、冰箱密封条等行业。

Abstract: Modern plastic plasticizer is the largest industrial

Additives varieties, to promote plastic industry especially polyvinyl

chloride (PVC) the development of industry plays a decisive role.

All that can be mixing and resin, mixed not chemistry, but can reduce the material glass transition temperature and the plastic molding process melt viscosity, and itself remains the same, or if the chemical change but can long-term retention in the plastic products and can change some of the physical properties of the resin, with these performance liquid organic compounds or low melting point of solid, are called plasticizers.

Plasticizer way according to their function can be divided into two categories, namely inside and outside the plasticizer plasticizer.

The environmental protection plasticizer epoxy fatty acid methyl ester synthesis process and the influence factors, the impact factors including formic acid, dosage of water.

Keywords: epoxy fatty acid methyl ester plasticizer catalytic of production process of epoxy polyvinyl chloride (PVC)
