SILICA-STYRENE-BUTADIENE RUBBER COMPOSITE AND MANUFACTURING METHOD THEREOF, RUBBER COMPOSITION, AND PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To provide a silica-styrene-butadiene rubber composite in which silica is minutely dispersed, and a manufacturing method thereof.

SOLUTION: The silica-styrene-butadiene rubber composite is obtained from compounded latex prepared by mixing emulsion-polymerized styrene-butadiene rubber latex and a fine particle silica dispersion having an average particle size of 1 μm or less in the presence of a nonionic surfactant and alkali.
