ABSTRACT:
A process for producing a rubber wet master batch contains at least a filler, a dispersing solvent and a rubber latex liquid as raw materials, comprising: a step (I) of, at the time of dispersing the filler into the dispersing solvent, adding at least one portion of the rubber latex liquid thereto, thereby preparing a slurry containing the filler to which rubber latex particles adhere; a step (II) of mixing the slurry with the rest of the rubber latex liquid, thereby preparing the rubber latex liquid containing the rubber-latex-particle-adhering filler; and a step (III) of solidifying and drying the rubber latex liquid containing the rubber-latex-particle-adhering filler.
