Abstract In order to develop an efficient and sustainable plasticizer, the waste cooking oil and malic acid were used as the main raw materials in this study to synthesize a bio-based plasticizer (acetylated-fatty acid methyl ester-malic acid ester, AC-FAME-MAE) by environment-friendly methods, and the structure was characterized by FTIR and 1H NMR. The properties of the poly (vinyl chloride) (PVC) with AC-FAME-MAE were tested and compared with those of the PVC plasticized with DOP (di-2-ethylhexyl phthalate) and EFAME (epoxy fatty acid methyl ester), respectively. The results of tensile test, TGA and leaching test showed that the mechanical properties, thermal stability and overall solvent resistance of PVC films with AC-FAME-MAE were significantly better than those of PVC films plasticized by DOP or EFAME. From the results of DMA, the plasticized efficiency of AC-FAME-MAE was as good as DOP. The application of AC-FAME-MAE has higher safety in the food industry based on the results of food simulation fluids experiment.

一种高效生物基废食用油增塑剂的合成及其在PVC中的性能测试

摘要 为了开发高效、可持续的增塑剂，本研究以废弃食用油和苹果酸为主要原料，合成了一种生物基增塑剂（乙酰化-脂肪酸甲酯-苹果酸酯，AC-FAME -MAE) 通过环境友好的方法，并通过 FTIR 和 1H NMR 对其结构进行表征。测试了含有 AC-FAME-MAE 的聚氯乙烯 (PVC) 的性能，并分别与用 DOP（邻苯二甲酸二-2-乙基己酯）和 EFAME（环氧脂肪酸甲酯）增塑的 PVC 的性能进行了比较。拉伸试验、TGA和浸出试验结果表明，含有AC-FAME-MAE的PVC薄膜的力学性能、热稳定性和整体耐溶剂性显着优于使用DOP或EFAME增塑的PVC薄膜。从 DMA 的结果来看，AC-FAME-MAE 的增塑效率与 DOP 一样好。基于食品模拟流体实验结果，AC-FAME-MAE在食品行业的应用具有更高的安全性。
