METHOD FOR MANUFACTURING RUBBER COMPOSITION

摘要

The present invention is a method for manufacturing a rubber composition that contains: a rubber component (A) comprising at least one type of rubber selected from among natural rubbers and synthetic diene rubbers; an inorganic filler (B); a silane coupling agent (C); and an acidic compound (D). Said manufacturing method is characterized in that: said rubber composition is kneaded in multiple stages; the acidic compound (D) is added in the final kneading stage; and the maximum temperature of the rubber composition during the final kneading stage is 60-120°C. This method for manufacturing a rubber composition is capable of suitably minimizing reductions in the coupling activity of the silane coupling agent, obtaining a rubber composition that generates less heat.
