| titleOfInvention | Rubber composition and tire produced using same, and process of producing rubber composition |
| abstract | The present invention relates to a rubber composition containing at least 10 parts by mass, in 100 parts by mass of a rubber component, of a polymer component (B) containing a residue of an organic acid (A) added in a production process of the polymer, and containing from 10 to 150 parts by mass of a reinforcing filler (C), and 6 parts by mass or less in total of the residue of an organic acid (A) and an organic acid (D) used on mixing, per 100 parts by mass of the rubber component, thereby providing a rubber composition that is excellent in low heat build-up property and wear resistance and a tire produced by using the composition, having the aforementioned properties, by defining the total amount of an acidic component with respect to the total mixed rubber, including an organic acid, such as stearic acid, and an organic acid contained in a residue of an emulsifier added in a production process of emulsion-polymerized SBR. The process of producing a rubber composition of the present invention is a process of producing a rubber composition containing a rubber component (R) containing emulsion-polymerized styrene-butadiene copolymer rubber containing from 0 to 3.5 parts by mass of an organic acid per 100 parts by mass of the emulsion-polymerized styrene-butadiene copolymer rubber, a filler containing an inorganic filler (T), a silane coupling agent (U), and at least one vulcanization accelerator (V) selected from a guanidine compound, a sulfenamide compound and a thiazole compound, and the process contains plural steps of kneading the rubber composition, where the rubber component (R), the whole or a part of the inorganic filler (T), the whole or a part of the silane coupling agent (U) and the vulcanization accelerator (V) are added and kneaded in a first step (X) of kneading, by which the activity reduction the coupling function of the silane coupling agent is favorably suppressed in the rubber composition containing emulsion-polymerized styrene-butadiene copolymer rubber for further enhancing the coupling function, thereby providing a rubber composition having favorable low heat build-up property. |
