METHOD FOR PRODUCING TIRE MATERIAL

The invention provides a method for producing a tire material that makes it possible to yield a vulcanized rubber high in anti-aging property (thermal deterioration resistance). The method comprises:a step (i) of mixing carbon black, a dispersing solvent and a rubber latex solution to produce a rubb...

Zusammenfassung:	The invention provides a method for producing a tire material that makes it possible to yield a vulcanized rubber high in anti-aging property (thermal deterioration resistance). The method comprises:a step (i) of mixing carbon black, a dispersing solvent and a rubber latex solution to produce a rubber latex solution including carbon black; a step (ii) of solidifying the resultant rubber latex solution including carbon black to produce a rubber solidified product including carbon black; a step (iii) of adding, to the resultant rubber solidified product including carbon black, a compound represented by the following formula (I), and dispersing the compound represented by the formula (I) into a water-containing rubber solidified product including carbon black while dehydrating the rubber solidified product including carbon black to produce a wet rubber masterbatch; and (iv) adding, to wet rubber masterbatch, the compound represented by the formula (I) and an anti-aging agent further, anddry-mixing these substanc
