Abstract

The present invention provides a method for producing a masterbatch and related products which enhance the dispersibility of fillers in rubber to improve the balance of tensile strength, rigidity, and fuel economy. Provided is a method for producing a masterbatch, including a step of mixing a rubber latex having a zeta potential of −100 to −20 mV with a filler dispersion having a zeta potential of 10 to 90 mV, and preparing a latex compound having a zeta potential of −20 to 0 mV.
