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降低,焦烧时间和t_(90)缩短,F_(max)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。The application of bio-based oils in the tread compound of passenger car tires was investigated.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 an unchanged or reduced Mooney viscosity of the compound,shortened scorch time and t_(90),decreased F_(max),decreased tensile stress at a given elongation 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,indicating better low-temperature performance.The loss factor(tanδ)at 0℃ decreased to varying degrees,while tanδ at 70℃ slightly increased for most bio-based oil compounds and significantly increased for some,leading to higher hysteresis loss.Overall,bio-based oils could replace heavy naphthenic oil,but the dosage of bio-based oil,sulfur,and fillers needed to be adjusted to meet performance requirements.
