Title:
METHOD FOR MANUFACTURING RUBBER COMPOSITION, RUBBER COMPOSITION, AND TIRE USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/026409
Kind Code:
A1
Abstract:
The present invention is a method for manufacturing a rubber composition that contains a rubber component, a resin, a reinforcing filler, and a cross-linker. Said method comprises: a first step in which a master batch is prepared by adding the resin to the rubber component; a second step in which a filled master batch is prepared by kneading the reinforcing filler into the master batch; and a third step in which the cross-linker is kneaded into the filled master batch. This makes it possible to obtain a rubber composition that is more elastic and has a high elongation-at-break.
