METHOD FOR PRODUCING RUBBER MIXTURE

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition which is suitable for the production of a NBR rubber suitable for producing winter tires and having devulcanization stability. SOLUTION: This method for producing a rubber mixture comprises a step for reacting a dienic elastomer, at least one light-colored reinforcing filler, and at least one polysulfide-containing alkoxysilane, and a step for mixing the obtained composition with a vulcanizing agent, at least one dithiophosphate compound and at least one vulcanization accelerator selected from sulfenamide compounds and thiazol compounds.
