摘　　要：报道了利用生物柴油制备环氧脂肪酸钙的方法,用刚果红试验、热烘试验、转矩流变仪混炼试验测试环氧脂肪酸钙作为聚氯乙烯(PVC)稳定剂的热稳定性能,同时分析其红外吸收光谱,测试其在应用于PVC时制品的力学性能,并与硬脂酸钙进行比较。结果表明:利用生物柴油制备环氧脂肪酸钙能改进工艺、降低成本;制备的环氧脂肪酸钙的热稳定性大于硬脂酸钙的,应用于PVC时制品的力学性能也好于使用硬脂酸钙的;可替代硬脂酸钙作为高效、无毒的PVC主稳定剂使用。The method of utilizing bio-diesel to prepare calcium epoxy soap was reported. The thermal stability of calcium epoxy soap as poly（vinyl chloride） （PVC） stabilizer was tested with congo red tests, oven tests, and torque rheometer process tests. Infrared absorption spectroscopies was analyzed and its effect on PVC samples mechanical behaviors was discussed in comparison with cal- cium stearate. The results show that calcium epoxy soap prepard by the method of utilizing bio- diesel can improve the manufacturing technique, and the production cost is low. The thermal stability of calcium epoxy soap is higher than that of calcium stearate, so its effect on PVC samples mechanical behaviors is better than that of calcium stearate. Therefore it can replace calcium stearate to be a high efficient and nonpoisonous PVC main stabilizer.
