摘要： 以棕榈酸和回收的聚乙二醇为原料，采用酯化法合成了一种脂肪酸酯类抗静电剂，研究了醇酸摩尔比、催化剂用量、反应时间和反应温度对酯化反应的影响。结果表明，在醇酸摩尔比为1.5:1，催化剂用量为0.8 %，反应时间为5 h，反应温度为140 ℃的条件下，所得产物的综合性能最好。将制备的脂肪酸酯应用于聚乙烯中作为抗静电剂，讨论了其含量、试样放置时间、环境温度对聚乙烯抗静电性能的影响，发现随着脂肪酸酯含量的增加、放置时间的延长和环境温度的升高，抗静电效果提高，当脂肪酸酯含量为3份时，抗静电效果最佳。

Abstract: An antistatic agent was synthesized by esterification reaction of recycled poly(ethylene glycol) (PEG) with palmitic acid. The effects of catalyst content，ratios of PEG to palmitic acid，reaction temperature and time on esterification reaction were studied. It showed that the optimum conditions were as follows: the molar ratio of PEG to palmitic acid was 1.5/1，the amount of catalyst was 0.8 %，the reaction temperature was 140 ℃, and the reaction time was 5 h. The obtained fatty acid ester was used to polyethylene (PE) as antistatic agent. The influences of amount of antistatic agent, storage time of PE sample, and environment temperature on antistatic property were investigated. It was found that the antistatic effect become more obvious with prolonged storage time and increased environment temperature. The optimum antistatic effect was obtained when the content of antistatic agent was 3 phr.

Key words: palmitic acid, antistatic agent, polyethylene, poly(ethylene glycol)
