| 中文摘要: |
| 对大型矿用工程机械子午线轮胎胎面基部胶配方进行优化。结果表明：通过适当调整胎面基部胶配方中的补强填充体系和硫化体系，并增加间苯二酚R-80和抗硫化返原剂WK-901，胶料的门尼粘度降低，门尼焦烧时间延长，硫化返原率减小；硫化胶的300%定伸应力、拉伸强度和回弹值增大，拉断永久变形减小，生热降低，耐热老化性能提高；成品轮胎的耐久性能提高，有效地减少了轮胎在使用过程中出现的生热脱层问题，提高了轮胎使用寿命。 |

| In this study，the base compound of off-the-road radial tire for mining was optimized.The results showed that，by adjusting reinforcing filler system and curing system of the base compound formula properly，and adding resorcinol R-80 and anti-reversion agent WK-901，the Mooney viscosity of the compound decreased，the Mooney scorch time was extended，and reversion rate was lowered.In addition，the modulus at 300% elongation，tensile strength and rebound value of the vulcanizate increased，the tensile permanent set decreased，the heat build-up decreased，and heat aging resistance was improved.With the optimized base compound，the endurance performance of finished tire was improved，the heat delamination problems in the tire using course was reduced，and the tire service life was extended. |
