摘　　要：对比分析不同碳型结构橡胶油对充油型不溶性硫黄性能及应用的影响。结果表明:相比芳香基橡胶油,环烷基橡胶油和石蜡基橡胶油不含有害芳烃,更为环保;芳香基橡胶油不溶性硫黄的热稳定性最差,石蜡基橡胶油不溶性硫黄的热稳定性较好,但易结块,分散性差,环烷基橡胶油不溶性硫黄的热稳定性和分散性最好;使用石蜡基橡胶油不溶性硫黄的硫化胶的物理性能最差,使用芳香基橡胶油不溶性硫黄的硫化胶的物理性能较好,使用环烷基橡胶油不溶性硫黄的硫化胶的物理性能最优。环烷基橡胶油是不溶性硫黄理想的填充油。The effects of rubber oils with different carbon type structures on the properties and applications of oil-filled insoluble sulfur were comparatively analyzed.The results showed that naphthenic rubber oil and paraffin based rubber oil were more environmentally friendly than aromatic rubber oil,as they did not contain harmful aromatics.Aromatic rubber oil insoluble sulfur had the worst thermal stability.The thermal stability of the paraffin based rubber oil insoluble sulfur was better,but it was prone to clumping and poor dispersibility.Naphthenic rubber oil insoluble sulfur had the best thermal stability and dispersibility.The physical properties of the vulcanizate with the paraffin based rubber oil insoluble sulfur were the worst,while the vulcanizate with the aromatic rubber oil insoluble sulfur had better physical properties.The physical properties of vulcanizate with the naphthenic rubber oil insoluble sulfur were the best.The naphthenic rubber oil was an ideal filling oil for insoluble sulfur.
