| 中文摘要: |
| 研究低滚动阻力改性剂Acroad DS-01T在半钢子午线轮胎胎面胶中的应用。结果表明：与生产配方胶料相比，试验配方胶料的损耗因子（tanδ）最大值减小0.14，60 ℃时的tanδ减小24%，0 ℃时的tanδ增大约3%；胶料的拉伸强度提高23%，撕裂强度提高6%，阿克隆磨耗量和DIN磨耗量分别减少19%和22%；试验配方成品轮胎的滚动阻力系数为8.86 N·kN-1，达到C级，抗湿滑指数为1.4，达到B级，满足GB/T 9743—2024《轿车轮胎》及欧盟标签法规（EU）No 2020/740和欧盟ECE R117轮胎法规第3版的要求。综上所述，加入低滚动阻力改性剂Acroad DS-01T有利于提高胎面胶的耐磨性能，提高轮胎的抗湿滑性能，降低轮胎的滚动阻力。 |

| The application of low rolling resistance modifiers Acroad DS-01T in the tread compound of steel-belted radial tire was studied.The results showed that compared with the production formula compound，the maximum loss factor（tanδ） value of the test formula compound decreased by 0.14，tanδ at 60 ℃ decreased by 24%，and tanδ at 0 ℃ increased by about 3%.The tensile strength of the rubber compound increased by 23%，the tear strength increased by 6%，and the Akron wear and DIN wear decreased by 19% and 22% respectively.The rolling resistance coeffecient of the test formula finished tire was 8.86 N·kN-1，reaching level C，and the wet slip index was 1.4，reaching level B，meeting the requirements of the national standard GB/T 9743—2024 "Car Tires"，EU labeling regulation（EU） No 2020/740 and EU ECE R117 tire regulation 3rd edition.In summary，adding Acroad DS-01T was beneficial for improving the wear resistance of the tread compound，enhancing the wet skid resistance of tire，and reducing the rolling resistance. |
