The rubber composition of the present invention contains a rubber wet-process masterbatch, rubber and carbon black (B) using a rubber latex solution and a slurry containing carbon black (A) as raw materials. 100 parts by weight of rubber components, the carbon black (A) in the rubber wet masterbatch is 1 to 35 parts by weight, relative to 100 parts by weight of the total rubber components in the rubber composition, the rubber composition The total amount of carbon black (A) and (B) in the content is 50 parts by weight or more. According to the present invention, a rubber composition capable of obtaining a vulcanized rubber having excellent low heat build-up properties and abrasion resistance, and a method for producing the same can be provided. |
