| 中文摘要: |
| 利用热重分析和高效液相色谱法，研究防老剂TMQ在不同温度下的热稳定性及其有效成分的含量变化。结果表明：防老剂TMQ在高温下有一定程度的质量损失，其有效成分的含量发生了变化；防老剂TMQ受胶料混炼温度及其添加顺序的影响较大，防老剂TMQ在二段混炼时加入，其有效成分的含量损失率小于防老剂TMQ在一段混炼时加入；当混炼温度为110 ℃时，硫化胶的物理性能较好。 |
| 英文摘要: |
| The thermal stability of antioxidant TMQ at different temperatures and the content changes of its active components were studied by thermogravimetric analysis and high performance liquid chromatography.The results showed that the antioxidant TMQ had a certain degree of quality loss at high temperature，and the content of its active components changed.The antioxidant TMQ was greatly affected by the mixing temperature and its adding sequence.When the antioxidant TMQ was added in the second stage of mixing process，the content loss rate of its active components was less than that of the antioxidant TMQ added in the first stage of mixing process.When the mixing temperature was 110 ℃，the physical properties of the vulcanizate were better. |
