    摘要: A method for producing a wet rubber masterbatch, comprising a step (I) of adding, at the time of dispersing the filler into the dispersing solvent, at least one portion of the synthetic styrene butadiene rubber latex solution into the dispersing solvent to produce a slurry solution comprising the filler to which rubber latex particles adhere, a step (II) of mixing the slurry solution with the rest of the rubber latex solution to produce a filler-containing rubber latex solution in which the rubber latex particles adhere to the filler, a step (III) of solidifying the filler-containing rubber latex solution, in which the rubber latex particles adhere to the filler, to produce a rubber solidified product, and a step (IV) of dehydrating and drying the rubber solidified product, wherein in anyone of the steps (I) to (IV), the rubber powder is mixed with the wet-rubber-masterbatch-producing phase present in the step.
