发明名称 Composite and method for producing the same, rubber composition, and pneumatic tire
摘要 The present invention aims to provide a composite including a rubber component in which surface-treated silica with a small particle size is uniformly dispersed, and a method for producing the composite. The present invention also aims to provide a rubber composition including the composite, the rubber composition capable of achieving both fuel efficiency and abrasion resistance while having excellent processability. The present invention also aims to provide a pneumatic tire including the rubber composition. The present invention relates to a composite formed from a compound latex prepared by mixing a natural rubber latex and a dispersion of surface-treated silica formed from a water glass, the surface-treated silica having an average particle size of not more than 100 nm and having a chemically-treated surface.

主权项 1. A composite, formed from a compound latex prepared by mixing a natural rubber latex with a dispersion of surface-treated silica formed from a water glass, the surface-treated silica having an average particle size of not larger than 100 nm and having a chemically-treated surface, wherein the surface of the silica is chemically treated with a compound containing a sulfur-containing functional group which is reactive with a double bond in a rubber of the natural rubber latex.
