| 中文摘要: |
| 研究异戊二烯橡胶（IR）在全钢子午线轮胎胎面胶中的应用及配方优化。结果表明：在全钢子午线轮胎胎面胶中将IR对天然橡胶（NR）替代量控制在30份以内，胶料的综合性能不发生显著变化；对于50份高替代量，通过增强硫化体系、增大炭黑用量以及钕系BR同步替代镍系BR，可以实现性能平衡。 |
| 英文摘要: |
| The application and formulation optimization of isoprene rubber（IR） in the tread compound for all-steel radial tire were studied.The results indicated that when the IR replacement amount for natural rubber（NR） in the tread compound for all-steel radial tire was controlled within 30 phr，the comprehensive performance of the compound remained unchanged.For a high replacement level of 50 phr，performance balance could be achieved by enhancing the vulcanization system，increasing the carbon black dosage，and substituting nickel-based BR with neodymium-based BR simultaneously. |
