| 中文摘要: |
| 研究功能助剂RK601（简称RK601）在全钢工程机械子午线轮胎基部胶中的应用。结果表明：与未加RK601的胶料相比，加入1份RK601的胶料的门尼粘度增大，门尼焦烧时间缩短，抗硫化返原时间延长；胶料的拉伸强度、拉断伸长率和撕裂强度基本相当，定伸应力略有升高，滞后损失和生热降低，抗刺扎性能提高；在轮胎基部胶中加入适量的RK601，可以提高轮胎的耐久性能。 |
| 英文摘要: |
| The application of functional additive RK601（abbreviated as RK601） in the base compound of all steel off-the-road radial tire was studied.The results showed that compared with the compound without RK601，the addition of 1 phr RK601 increased the Mooney viscosity，shortened the Mooney scorch time，and prolonged the anti-reversion time of the compound.The tensile strength，elongation at break，and tear strength of the vulcanizate were basically equivalent，with a slight increase in tensile stress and a decrease in hysteresis loss and heat build-up of the vulcanizate.The durability of finished tire was improved. Adding appropriate amount of RK601 in the tire base compound could improve the durability of the tire. |
