| 中文摘要: |
| 试验研究在典型的白炭黑胎面胶配方中用促进剂DPT和TATD替代促进剂DPG的应用效果。结果表明：虽然促进剂DPG高温裂解会产生苯胺危害人体健康和环境，但其在白炭黑胎面胶配方中的综合性能优势比较明显；促进剂DPT替代促进剂DPG在硫化体系上需要进行适当调整，同时要注意其对胶料门尼粘度、拉伸强度及拉断伸长率等的影响；促进剂TATD替代促进剂DPG的难度较大，替代后混炼胶加工性能和硫化胶物理性能都发生了比较明显的变化；在白炭黑胎面胶配方中促进剂DPG替代不能进行简单的品种更换，同时需对配方其他组分进行优化调整。 |
| 英文摘要: |
| The application effect of accelerator DPT and TATD instead of accelerator DPG in typical silica tread compound was studied.The results showed that，although the high temperature cracking of accelerator DPG could produce aniline，which was harmful to human health and the environment，its comprehensive performance advantage in the formula of silica tread compound was obvious.When the accelerator DPT instead of DPG，the vulcanization system should be properly adjusted，and its effects on Mooney viscosity，tensile strength and elongation at break of compound should be paid attention to.It was difficult for accelerator TATD to replace accelerator DPG，and obvious changes had taken place in the processability of compound and the physical properties of vulcanizate.In the formula of silica tread compound，the accelerator DPG could not be replaced by simple variety change，and other components of the formula needed to be optimized and adjusted. |
