  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。

  The invention is a process for producing a rubber composition containing at least one rubber component (A) selected from natural rubbers and synthetic diene rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C) and a vulcanization accelerator (D), wherein the rubber composition is kneaded in multiple stages, the rubber component (A), all or a portion of the inorganic filler (B), all or a portion of the silane coupling agent (C) and the vulcanization accelerator (D) are added and kneaded in the first stage of kneading, and the specific energy for kneading in the first stage is from 0.05 to 1.50 kWh/kg. The specific energy is obtained by dividing the power consumption by the motor in the kneading device in the first stage of kneading by the total mass of the rubber composition therein. In the process, the coupling function activity can be further increased and a rubber composition favorably having a low-heat-generation property and having good abrasion resistance can be obtained.

  本发明是一种生产橡胶组合物的工艺，该橡胶组合物含有至少一种选自天然橡胶和合成二烯橡胶的橡胶组分（A）、一种含有无机填料（B）的填料、一种硅烷偶联剂（C）和一种硫化促进剂（D），其中橡胶组合物分多个阶段捏合、在第一阶段混炼中加入并混炼橡胶成分 (A)、全部或部分无机填料 (B)、全部或部分硅烷偶联剂 (C) 和硫化促进剂 (D)，第一阶段混炼的比能量为 0.05 至 1.50 千瓦时/千克。比能量是通过将第一阶段混炼中混炼装置中电机的耗电量除以其中橡胶组合物的总质量得出的。在此过程中，耦合功能活性可进一步提高，并可获得具有低发热特性和良好耐磨性的橡胶组合物。
