| 中文摘要: |
| 研究防老剂FR在巨型工程机械轮胎胎面基部胶中的应用。结果表明：在巨型工程机械轮胎胎面基部胶中用防老剂FR等量代替防老剂RD，胶料焦烧时间延长，硫化速度减慢，加工性能良好；对胶料物理性能无不良影响，胶料耐热氧老化性能提高，动态生热性能改善；有利于避免轮胎早期损坏，延长使用寿命。 |
| 英文摘要: |
| In this study， antioxidant FR was applied in the tread base compound of giant OTR tire， replacing antioxidant RD at the same addition level in the original formulation. The experimental test results showed that the scorch time was prolonged and the curing speed decreased， indicating good processing properties. Antioxidant FR showed no negative effect on the physical properties of the base compound. On the other hand， the thermal oxidative aging resistance was improved and heat build-up was reduced， which could reduce the early damage of tires and prolong the tire service life. |
