ABSTRACT:
A silica-blended rubber composition comprising 100 parts by weight of sulfur-vulcanizable rubber blended with 10 to 100 parts by weight of silica, 3 to 20% by weight of a silane coupling agent based on the silica and 1 to 20% by weight of sodium borate based on the silica. An alkoxy group-containing silane coupling agent is preferred as the silane coupling agent, and sodium tetraborate is preferred as the sodium borate.
