Abstract

A process for producing a wet rubber masterbatch yielded by using, as raw materials, at least a filler, a dispersing solvent, and a rubber latex solution, comprises a step (i) of mixing the filler, the dispersing solvent and the rubber latex solution with each other to produce a filler-containing rubber latex solution, a step (ii) of solidifying the filler-containing rubber latex solution to produce a filler-containing rubber solidified product, and a step (iii) of dehydrating the filler-containing rubber solidified product to produce the wet rubber masterbatch. At the time of representing the temperature of the filler-containing rubber solidified product before the dehydration in the step (iii) by T1 (° C.), and representing the temperature of the filler-containing rubber solidified product after the dehydration by T2 (° C.), the following expressions (1) and (2) are satisfied:
