| 中文摘要: |
| 研究生物基油在乘用车轮胎胎面胶中的应用。结果表明：在以溶聚丁苯橡胶（SSBR）为主胶、填充白炭黑的配方体系中，使用4种生物基油等量替代重质环烷油，胶料的门尼粘度不变或有降低，焦烧时间和t90缩短，Fmax下降，定伸应力有不同程度的降低，拉伸强度、耐磨性能相当或提高；玻璃化转变温度降低3～7 ℃，大部分生物基油胶料低温模量大幅下降，低温性能较好；0 ℃时的损耗因子（tanδ）有不同程度减小，多数生物基油胶料70 ℃时的tanδ略增大，部分生物基油胶料明显增大，滞后损失增加。综合而言，生物基油可以替代重质环烷油使用，但需要对生物基油、硫黄及填料等的用量进行调整，以满足性能要求。 |
| 英文摘要: |
| The application of bio-based oil in the tread compound of passenger car tire.The results showed that in a formulation system mainly composed of solution polymerized styrene butadiene rubber and filled with white carbon black，using four types of bio-based oils in equal amounts to replace heavy naphthenic oil resulted in a constant or reduced Mooney viscosity of the compound，shortened scorch time and t90，decreased Fmax，decreased tensile stress to varying degrees，and equivalent or improved tensile strength and wear resistance.The glass transition temperature decreased by 3～7 ℃，and the low-temperature modulus of most bio-based oil compounds decreased significantly，resulting in better low-temperature performance.The loss factor（tanδ） at 0 ℃ decreased to varying degrees，with most bio-based oil compounds having a slight increase in tanδ at 70 ℃，while some bio-based oil compounds had a significant increase，resulting in increased hysteresis losses.Overall，bio-based oil could replace heavy naphthenic oil，but the dosage of bio-based oil，sulfur，and fillers needed to be adjusted to meet performance requirements. |
