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. |
