| 中文摘要: |
| 通过单一加入方式，选出不同温度下稳定效果较好的不溶性硫黄（IS）稳定剂，并根据试验结果对IS稳定剂作用机理进行初步探究。在105 ℃时，松节油、苯乙烯、促进剂DM以及复合稳定剂（主要组分为黄原酸酯、氯化苄和邻苯二甲醇二丁酯）能够提升IS的稳定性，其中促进剂DM对IS的稳定效果最好；在120℃时，松节油与苯乙烯对IS的稳定效果极弱，促进剂DM和复合稳定剂对IS仍具有稳定效果，其中复合稳定剂的稳定性效果最好。 |
| 英文摘要: |
| Through a single addition method，selected insoluble sulfur（IS） stabilizers with better stabilizing effect at different temperatures，and conducted a preliminary study on the mechanism of IS stabilizers based on the test results. At 105 ℃，turpentine，styrene，accelerator DM and composite stabilizer （the main components were oxalate，benzyl chloride and dibutyl phthalate） could improve the stability of IS. Among them，accelerator DM had the best stabilizing effect on IS. At 120 ℃，the stabilizing effect of turpentine and styrene on IS were extremely weak，the accelerator DM and composite stabilizer still had a stabilizing effect on IS，and the composite stabilizer had the best stabilizing effect. |
