Method for producing rubber composition |
| abstract |
After step (I) of kneading a diene rubber and a carbon black to be mixed with each other, and then discharging the resultant mixture containing the diene rubber and the carbon black from an internal mixer, step (II) of kneading the mixture again in the internal mixer to crush a re-aggregate of the carbon black in the mixture, and step (III) of charging the dihydrazide compound into the internal mixer, and kneading the mixture and the dihydrazide compound to be mixed with each other are carried out. The period of step (II) for the kneading is 15 seconds or longer, and the rotating speed of the stirring rotor of the internal mixer is 35 rpm or more. The period of step (III) for the kneading is 40 seconds or longer, and the rotating speed of the stirring rotor of the internal mixer is from 15 to 25 rpm. |
