摘要:
The invention relates to preparation of silica-rich rubber compositions for a tire by a sequence of sequential mixing steps conducted in internal rubber mixer(s) with individual maximum temperature limitations. The mixing steps are comprised of at least two non-productive mixing steps followed by a productive mixing step. The non-productive mixing steps themselves are comprised of at least one preliminary non-productive mixing step followed by a final non-productive mixing step. Elastomer, silica and coupling agent are added in at least one of said preliminary non-productive mixing steps to the exclusion of said final non-productive mixing step and said productive mixing step. Sulfur and sulfur vulcanization accelerator(s) are added in said productive mixing step to the exclusion of said non-productive mixing steps.
