Abstract

A method for producing a rubber wet master batch using, as raw materials, at least a rubber powder, a filler, a dispersing solvent, and a rubber latex solution, comprises a step (I) of adding, at a time of dispersing the rubber powder in the dispersing solvent, at least one portion of the rubber latex solution to the dispersing solvent to produce a rubber powder solution containing the rubber powder to which rubber latex particles adhere, a step (II) of adding the filler to the rubber powder solution, and mixing the solution and the filler with each other to produce a rubber-powder-containing slurry solution, and a step (III) of mixing the rubber-powder-containing slurry solution with a rest of the rubber latex solution, and then solidifying/drying the resultant mixture.
