| 中文摘要: |
| 研究改性溶聚丁苯橡胶（FSSBR）/天然橡胶（NR）并用比对新能源汽车轮胎超低滚动阻力胎面胶性能的影响。结果表明：随着FSSBR/NR并用比的增大，混炼胶的门尼粘度升高，硫化速度降低，可通过加工助剂和第二促进剂调节；硫化胶的硬度减小，300%定伸应力和摩擦因数增大，拉伸强度和拉断伸长率先增大后趋于稳定，耐低温性能降低，生热性能和滞后性能变化不大，FSSBR/NR并用比为62∶38时，硫化胶的综合性能最优；采用FSSBR/NR并用比为62∶38的配方胶料作为胎面胶试制成品轮胎的抗湿滑性能和滚动阻力分别达到欧盟标签法规B和A级，与竞品轮胎相比，试验轮胎的制动性能更优，滑行距离更大，表明轮胎的滚动阻力更低。 |
| 英文摘要: |
| Effect of modified solution-polymerized styrene-butadiene rubber（FSSBR）/natural rubber（NR） blend ratios on performance of ultra-low rolling resistance tread compounds for new energy vehicle tires was studied.The results showed that as the FSSBR/NR blend ratio increased，the Mooney viscosity of the compound rubber increased，while the vulcanization rate decreased，which could be adjusted by processing aids and secondary accelerators.The hardness of the vulcanizate decreased，while the modulus at 300% elongation and friction coefficient increased.The tensile strength and elongation at break initially increased and then stabilized，whereas the low-temperature resistance decreased.The heat build-up and hysteresis properties showed little change.When the FSSBR/NR blend ratio was 62∶38，the vulcanizate exhibited optimal overall performance.Using a formulation with an FSSBR/NR blend ratio of 62∶38，the test tire with the tread compound achieved wet skid resistance and rolling resistance levels of EU label grades B and A，respectively.Compared to competitor tires，the test tire demonstrated superior braking performance and longer sliding distances，indicating lower rolling resistance. |
