发明名称 RUBBER COMPOSITION MANUFACTURING METHOD, RUBBER COMPOSITION, AND PNEUMATIC TIRE USING SAME
摘要 <p>The present invention provides a method for producing a rubber composition provided by compounding a rubber component (A) comprising at least one selected from natural rubbers and synthetic diene rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C), and at least one vulcanization accelerator (D) selected from specific compounds, wherein the rubber composition is kneaded in a plurality of stages and wherein, in the first stage (X) of kneading, a portion (A') of the rubber component (A), all or a portion of the inorganic filler (B), all or a portion of the silane coupling agent (C), and all or a portion of the vulcanization accelerator (D) are added and kneaded, and in or after the second stage of kneading, the residual portion (A") of the rubber component (A) is added and kneaded, and the method for producing a rubber composition enables production of a rubber composition capable of suitably having a low-heat-generation property by further improving the coupling function activity of the silane coupling agent therein.</p>
