| 中文摘要: |
| 在顶空瓶中以热空气老化的方式模拟轮胎硫化条件，采用气相色谱/质谱法分析4种常用促进剂（MBT，CBS，TBBS和DPG）及其混炼胶硫化烟气中的含氮组分。在检测到的26种含氮物质中，确定了15种成分的化合物结构。结果表明：4种促进剂及其混炼胶硫化烟气中的含氮组分种类从少到多依次为DPG，MBT，CBS，TBBS；促进剂DPG及其混炼胶硫化烟气中的苯胺含量较大，应尽量避免使用促进剂DPG；促进剂MBT混炼胶硫化烟气中的含氮组分种类少，毒性较低，是环保型促进剂。 |
| 英文摘要: |
| The nitrogen-containing components in the vulcanization fume of four commonly used curing accelerators（MBT，CBS，TBBS and DPG） and the compounds with those four accelerators were analyzed by gas chromatography/mass spectrometry method，the vulcanization fume was obtained by using hot air aging in a headspace bottle which simulated the tire curing condition. 26 nitrogen-containing components were detected，in which the chemical structures of 15 components were identified. The results showed that the amounts of the nitrogen-containing components in the four accelerators and vulcanization fumes of their compounds increased in the order of：DPG，MBT，CBS，TBBS. The vulcanization fume of accelerator DPG and its compound possessed a high level of aniline，so that accelerator DPG should be avoided in compound formulation. The vulcanization fume of accelerator MBT and its compound had less nitrogen-containing components and lower toxicity，indicating that accelerator MBT was an environmentally friendly accelerator. |
