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.
