| 发明名称 | Method for manufacturing rubber composition | ||
| 摘要 | The present invention provides a method for producing a rubber composition containing a rubber component (A) of at least one selected from natural rubbers and synthetic dienic rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C) and at least one vulcanization promoter (D) selected from thiurams, dithiocarbamate salts, thioureas and xanthate salts, wherein the rubber composition is kneaded in multiple stages, and in the first stage of kneading, the rubber component (A), all or a part of the inorganic filler (B), all or apart of the silane coupling agent (C) and the vulcanization promoter (D) are kneaded. The production method enables production of a rubber composition having a low-heat-generation property while successfully enhancing the coupling function activity of the silane coupling agent. | ||
