Method of preparing wet master batch elastomer composition for making rubber with excellent processability and abrasion resistance

Abstract

Disclosed is a method of preparing a wet master batch elastomer composition, including: a first step of inputting silica particles and an organic silane coupling agent into a SSBR polymer solution; a second step of stirring the SSBR polymer solution containing the silica particles and the organic silane coupling agent to pulverize the silica particles while surface-modifying the silica particles with the organic silane coupling agent; a third step of removing a solvent from the SSBR polymer solution containing the surface-modified and pulverized silica particles, followed by drying and solidification to obtain a silica-SSBR composite; and a fourth step of compounding the silica-SSBR composite with one or more additives selected from the group consisting of silica particles, an organic silane coupling agent, a softener, a crosslinking activator, an antioxidant, a vulcanization accelerator, and a vulcanizing agent, wherein the wet master batch elastomer composition includes 8 to 20 parts by weight of the organic silane coupling agent based on 100 parts by weight of the SSBR polymer solution.
