| description | The present invention relates to a process for producing a rubber composition comprising greater than 50 phr of a diene elastomer rich in ethylene units, a reinforcing filler comprising carbon black, and a vulcanization system, the vulcanization system comprises sulfur, sulfenamide as a primary accelerator and thiuram polysulfide or a mixture of thiuram polysulfide and guanidine as a secondary accelerator, the method comprises mixing a highly saturated diene elastomer, a reinforcing filler and a secondary accelerator by kneading at a temperature above 110 DEG C in the absence of sulfur and a primary accelerator, and introducing sulfur and the primary accelerator into the rubber composition by kneading at a temperature below 110 DEG C. The method can reduce hysteresis of the vulcanized rubber composition.
本发明涉及一种生产橡胶组合物的方法，所述橡胶组合物包含大于50phr的富含乙烯单元的二烯弹性体、增强填料和硫化体系，所述增强填料包含炭黑，所述硫化体系包含硫、作为主促进剂的次磺酰胺和作为次促进剂的秋兰姆多硫化物或者秋兰姆多硫化物和胍的混合物，所述方法包括在不存在硫和主促进剂的情况下在高于110℃的温度下通过捏合混合高度饱和的二烯弹性体、增强填料和次促进剂，以及在低于110℃的温度下通过捏合将硫和主促进剂引入到橡胶 |
