| 中文摘要: |
| 采用闪蒸气相色谱-质谱联用法鉴定硫化胶中常用的促进剂种类。结果表明：当特征反应产物仅有苯并噻唑基团时，促进剂为MBT或MBTS；当特征反应产物除苯并噻唑外，还有叔丁胺、环己胺或二环己胺基团时，可分别判定为促进剂TBBS，CBS，DCBS或其与促进剂MBT/MBTS共存。本方法采用裂解器直接进行硫化胶样品闪蒸，分析效率高，结果准确可靠。 |
| 英文摘要: |
| The types of accelerators used in vulcanizates were identified by flash evaporation gas chromatography-mass spectrometry（GC-MS）.The results showed that when the characteristic reaction product only had benzothiazole group，the accelerator was MBT or MBTS.When the characteristic reaction products also had the groups of tert-butylamine，cyclohexamine or dicyclohexamide besides benzothiazole，it could be determined as the accelerator TBBS，CBS，DCBS or coexistence with accelerator MBT/MBTS respectively.The method was used to flash evaporation vulcanizate samples directly by a pyrolysis device，which had high efficiency and reliable results. |
