シリカ・スチレンブタジエンゴム複合体及びその製造方法、並びにゴム組成物及び空気入りタイヤ

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.
