Abstract
Official abstract text for this publication.
The present invention provides a rubber composition containing: (A) a rubber component containing 10% by mass or more of at least one kind of rubber selected from diene rubber synthesized by emulsion polymerization and natural rubber and 90% by mass or less of another kind of diene rubber; (B) silica having a n-hexadecyltrimethylammonium bromide (CTAB) adsorption specific surface area of not less than 180 m 2 /g measured according to a method described in ASTM D3765-92; (C) at least one silane coupling agent selected from a polysulfide compound and a thioester compound; and (D) a vulcanization accelerator, the rubber composition after vulcanization having an average aggregated aggregate area (nm 2 ) of the silica of 1,900 or less, and thus provides a rubber composition that is improved in low-heat-generation property.
