| 中文摘要: |
| 采用热重分析法（TG）和裂解气质联用法（PGC-MS）对3种典型的次磺酰胺类橡胶硫化促进剂的热裂解行为进行初步研究。结果表明：在选定的分析条件下，TG法和PGC-MS法分析结果有一定的一致性；TG分析中，促进剂NS的质量损失初始温度、质量损失最快温度和质量损失终止温度均最低，促进剂CZ其次，促进剂DZ最高，促进剂CZ质量损失速率最大；PGC-MS分析中3种促进剂均可以检测到其原分子，小分子胺为区分3种次磺酰胺类硫化促进剂的主要标志物。 |
| 英文摘要: |
| The pyrolysis behavior of three typical sulfenamide-based vulcanization accelerators，NS，CZ and DZ，was investigated by thermogravimetric analysis（TG） and pyrolysis combined with GC-MS（PGC-MS）．The analysis result by TG and PGC-MS methods had a certain consistency under the selected conditions．The initial weight loss temperature，the fastest weight loss temperature and the terminating weight loss temperature of the accelerator NS in TG analysis were the lowest，while those of the accelerator DZ were the highest，respectively．The weight loss rate of the accelerator CZ was the largest．In the analysis of PGC-MS，the original molecules of the three accelerators could all be detected．The small molecule amines were the main markers for distinguishing three sulfenamide-based vulcanization accelerators. |
