The potential replacement of a treated residual aromatic extract mineral oil (TRAE) by a highly epoxidized soybean oil (ESO) into a silica-filled styrene-butadiene rubber compound was investigated.

In order to determine if ESO compounds performance are suitable for tread tire applications, processing properties cure and characteristics were evaluated. The impact of ESO amount on the silica dispersion was confirmed by Payne Effect. The presence of chemical or physical interactions between ESO and silica improves the filler dispersion, enabling the compound processability and affecting the cure kinetic rate.

An adjusted rubber compound with 2 phr of ESO and 2 phr of sulfur presented the higher stiffness and strength values with lower weight loss from a wear test compared with TRAE compound at an equal amount of oil and curing package. Furthermore, wet grip and rolling resistance predictors of both compounds gave comparable results, maintaining a better performance and reducing the dependence of mineral oil for tire tread compounds.

研究了用高度环氧化大豆油 (ESO) 将处理过的残留芳香族萃取矿物油 (TRAE) 替代为填充二氧化硅的丁苯橡胶化合物的可能性。

为了确定 ESO 化合物的性能是否适用于胎面轮胎应用，评估了加工性能固化和特性。佩恩效应证实了 ESO 量对二氧化硅分散体的影响。ESO 和二氧化硅之间化学或物理相互作用的存在改善了填料的分散性，提高了胶料的可加工性并影响了固化动力学速率。

与等量的油和硫化包的 TRAE 化合物相比，具有 2 份 ESO 和 2 份硫的调整过的橡胶化合物表现出更高的刚度和强度值，磨损试验中的重量损失更低。此外，两种化合物的湿抓地力和滚动阻力预测器给出了类似的结果，保持了更好的性能并减少了矿物油对轮胎胎面化合物的依赖。
