METHOD FOR MANUFACTURING RUBBER COMPOSITION, RUBBER COMPOSITION, AND TIRE USING SAME

The present invention is a method for manufacturing a rubber composition containing a rubber component, a resin, a reinforcing filler and a crosslinking agent, and the method contains: a first step of adding the resin to the rubber component to produce a master batch; a second step of kneading the master batch with the reinforcing filler to produce a filled master batch; and a third step of kneading the filled master batch with the crosslinking agent, thereby providing a rubber composition having higher elasticity and large breaking elongation.
