| 中文摘要: |
| 研究非环保促进剂DCBS在全钢载重子午线轮胎胎圈耐磨胶中的替代方案。结果表明：采用促进剂CBS和TBBS等量及减量替代促进剂DCBS时，胶料的硫化速度明显较快，t90缩短近1/2，焦烧时间缩短，加工安全性较差；采用促进剂TBSI等量及减量替代DCBS时，胶料的硫化速度相当，加工安全性较好；采用促进剂CBS，TBBS和TBSI分别等量替代促进剂DCBS时，胶料的定伸应力、硬度和回弹值增大，拉断永久变形减小，拉断伸长率和撕裂强度下降，温升和损耗因子降低；采用促进剂TBSI减量替代促进剂DCBS时，胶料的综合性能最好。可以采用促进剂TBSI减量替代促进剂DCBS应用于胎圈耐磨胶。 |
| 英文摘要: |
| The alternative scheme of non environmentally friendly accelerator DCBS in the bead wear-resistant compound of all-steel truck and bus radial tire was studied. The results showed that，when using equal or reduced amounts of accelerator CBS and TBBS instead of accelerator DCBS，the vulcanization rate of the compound was significantly faster，the t90 was shortened by nearly half，the scorching time was shortened，and the processing safety was poor.When using equal and reduced amounts of accelerator TBSI instead of accelerator DCBS，the vulcanization rate of the compound was comparable，and the processing safety was better.When using equal amount of accelerators CBS，TBBS，and TBSI instead of accelerator DCBS，the tensile stresses，hardnesses and rebound values of the compounds increased，while the permanent deformation at break decreased，the elongation at break and tear strength decreased，the temperature rise and loss factor decreased.When using reduced amount of accelerator TBSI instead of accelerator DCBS，the compound had the best comprehensive performance.Accelerator TBSI could instead of accelerator DCBS with reducing amount in bead wear-resistant compound of tire. |
