Document Type and Number:
Japanese Patent JP2015030825
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rubber wet master batch capable of enhancing the drying efficiency of a coagulum in a drying stage and stabilizing the rubber physical properties of a vulcanized rubber to be obtained.SOLUTION: A method for producing a rubber wet master batch comprises: a step (I) of dispersing a filler in a dispersing solvent to produce a filler-containing slurry solution; a step (II) of mixing the filler-containing slurry solution with a rubber latex solution to produce a filler-containing rubber latex solution; a step (III) of coagulating the filler-containing rubber latex solution; and a step (IV) of separating and drying the coagulum obtained in the step (III) from the solution to produce the rubber wet master batch. In the method for producing the rubber wet master batch, wax is added in any of the step (I) to the step (III), and at least one of the step (I) to the step (III) performed after the wax addition is performed at a temperature of equal to or more than a melting point of the wax.
