The invention relates to the field of rubber tire manufacturing, in particular to an ultralow-rolling-resistance rubber composition for a four-season tire, a mixing method of the ultralow-rolling-resistance rubber composition and the tire. According to the invention, the silane coupling agent is adopted to pre-react the nano silicon dioxide, and then the modified nano silicon dioxide and other raw materials are mixed, so that the emission of VOC is effectively avoided, the useless cost and the use cost of equipment and instruments in a mixing formula are reduced, and the silane coupling agent pre-reacted nano silicon dioxide does not need to be subjected to silanization reaction at a constant temperature; and the mixing efficiency is further improved.
本发明涉及橡胶轮胎制造领域,具体涉及一种用于四季轮胎的超低滚动阻力橡胶组合物及其混炼方法和轮胎。本发明采用了硅烷偶联剂预反应纳米二氧化硅,再将改性后的纳米二氧化硅和其他原料混炼,有效避免了VOC排放,降低了混炼配方中的无用成本和设备仪器使用成本,而且通过硅烷偶联剂预反应纳米二氧化硅不需要恒温进行硅烷化反应,进一步提高了混炼效率。
