  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, an inorganic filler (B), a silane coupling agent (C) and an acidic compound (D), wherein the rubber composition is kneaded in multiple stages, and in the final stage of kneading, the acidic compound (D) is added, and the highest temperature of the rubber composition in the final stage of kneading is from 60 to 120°C. The production method enables production of a rubber composition having a low-heat-generation property while successfully preventing the coupling function activity of the silane coupling agent from lowering.

  本发明提供了一种橡胶组合物的生产方法，该橡胶组合物含有至少一种选自天然橡胶和合成二元橡胶的橡胶组分（A）、无机填料（B）、硅烷偶联剂（C）和酸性化合物（D），其中橡胶组合物经过多阶段捏合，在捏合的最后阶段加入酸性化合物（D），在捏合的最后阶段橡胶组合物的最高温度为 60 至 120°C。该生产方法既能生产出具有低发热特性的橡胶组合物，又能成功防止硅烷偶联剂的偶联功能活性降低。
