| 中文摘要: |
| 研究促进剂TBBS粒径分布对全钢载重子午线轮胎胎面胶性能的影响。结果表明：促进剂TBBS粒径分布对胶料门尼粘度、门尼焦烧时间、硫化速度及导热性能的影响较小；粒径分布因数最大的促进剂TBBS在胶料中的分散性最好，硫化胶的拉伸性能、耐热性能和耐磨性能最佳，回弹值最大，生热最低，60 ℃时的损耗因子最小。 |
| 英文摘要: |
| The effect of particle size distribution of accelerator TBBS on the properties of tread compound of truck and bus radial tire was studied.The results showed that the particle size distribution of accelerator TBBS had little effect on the Mooney viscosity，Mooney scorch time，vulcanization speed and thermal conductivity of the compound.The accelerator TBBS with the largest particle size distribution factor had the best dispersion in the compound，the best tensile properties，heat resistance and wear resistance of the vulcanizate，the largest rebound value，the lowest heat build-up and the smallest loss factor at 60 ℃. |
