| 中文摘要: |
| 研究高分散性白炭黑在半钢子午线轮胎胎面胶配方中的应用。结果表明：在胎面胶配方中用高分散性白炭黑等量代替普通白炭黑，胶料的加工安全性提高，t90稍长，硫化胶的300%定伸应力下降，DIN磨耗量减小，生热稍有降低，老化后性能保持率提高；成品轮胎的高速性能和耐久性能保持不变，滚动阻力降低。 |
| 英文摘要: |
| The application of highly dispersed silica in the tread compound formula of steel-belted radial tire was studied.The results showed that，when highly dispersed silica was used to replace ordinary silica equivalently in tread compound formula，the processing safety of the compound was improved，the t90 was slightly longer，the modulus at 300% elongation of the vulcanizate decreased，the DIN abrasion value decreased，the heat build-up decreased slightly，and theproperties retention rate was improved after aging.The high speed performance and durability of the finished tire remained unchanged，and the rolling resistance was reduced. |
