摘　　要：采用硬脂酸对三氧化二锑(Sb2O3)进行表面改性,并通过活化指数、红外光谱等检测对改性效果进行了表征。通过单因素实验研究了改性Sb2O3对软质PVC复合体系阻燃性能和力学性能的影响。结果表明:当改性Sb2O3在软质PVC复合体系中的用量为3 phr时,体系的阻燃性能和力学性能达到最佳。The surface modification of Sb2O3 by stearic acid was investigated, and the modification effects were characterized by activation index and Fourier transform infrared spectroscopy （FTIR）. The influences of the modified Sb2O3 content on flame retardant properties and mechanical properties of the PVC compound system were studied by single-factor experiment. The results indicate that when the modified Sb2O3 content is 3 phr, the PVC compound system shows the optimum comprehensive properties.
