摘要：以大豆油为起始原料,经过环氧化、酯交换等反应制得环氧大豆油脂肪酸甲酯(ESAO);然后,ESAO、醋酸和醋酸酐“一锅法”反应制备出大豆油脂肪酸多酯(SF-PE)。GC分析表明:ESAO中的甲酯大于96%;IR、1HNMR和13CNMR等分析手段对产物结构表征,证明了SF-PE被成功合成;TG分析表明SF-PE的热稳定性能要优于ESAO。对比分析了以SF-PE、ESAO、环氧大豆油(ESO)和市售环氧脂肪酸甲酯(EFAM)作为增塑剂制备PVC制品的机械性能、动态机械性能和热稳定性,用树脂量50%的SF-PE增塑PVC样品的拉伸强度为19MPa,邵氏硬度为90.2,综合机械性能优于其他3种增塑剂,玻璃化转变温度(Tg)为26.4℃;SF-PE增塑PVC样品的耐低温性能优于ESO;热稳定性与ESAO相当,要优于EFAM,但是不及ESO。
Epoxidized soybean oil methyl ester (ESAO) was prepared by epoxy reaction and then followed by transesterification using soybean oil as starting material. Then, soybean oleic acid polyester (SF-PE) was prepared by one-pot reaction with ESAO, acetic acid and acetic anhydride. The purity of ESAO was more than 96% by GC analysis, and the structures of products were characterized by IR, 1 H NMRand 13 C NMR. It was proved that epoxidation, ring opening and esterification occurred and SF-PE was successfully synthesized. The thermal stability of SF-PE was better than ESAO according to TG analysis. The mechanical properties, dynamic mechanical properties (DMA) and TG of PVC samples prepared with SF-PE, ESAO, epoxy soybean oil (ESO) and epoxy fatty acid methyl ester (EFAM) as plasticizers were compared and analyzed. The tensile strength and hardness of PVC samples were 19 MPa and 90. 2 HD when the dosage of SF-PE was 50% of the weight of resin. The comprehensive mechanical properties of PVC samples were optimized, and the glass transition temperature (T g ) was 26. 4 ℃. Its low temperature resistance is superior to ESO, and its thermal stability is similar to ESAO, superior to EFAM, but inferior to ESO.
