Abstract
A masterbatch manufacturing method comprising: an operation in which a natural rubber latex, and a rubber latex having a mass-average molecular weight that is less than a mass-average molecular weight of the natural rubber latex, are mixed to obtain a pre-slurry-mixing rubber latex for which a mass-average-molecular-weight-to-number-average-molecular-weight ratio is 6 to 10; an operation in which the pre-slurry-mixing rubber latex and a filler slurry are mixed to obtain a pre-coagulation liquid mixture; and an operation in which the pre-coagulation liquid mixture is coagulated.
