    Abstract: A method for producing a rubber wet masterbatch includes a solidifying step of mixing a slurry solution containing a filler and a dispersing solvent with a rubber latex solution, and solidifying the resultant mixture to produce a filler-containing rubber solidified product, a dehydrating step of using a first uniaxial extruder to dehydrate the filler-containing rubber solidified product while the solidified product is heated into the range of 100 to 180° C., thereby producing a rubber wet masterbatch, and a drying plasticizing step of using a second uniaxial extruder to plasticize the rubber wet masterbatch while the masterbatch is heated into the range of 120 to 180 C, thereby producing the rubber wet masterbatch further decreased in water content by percentage. The method does not have cooling step between the dehydrating step and the drying plasticizing step.
