Silica and Silane Coupling Reinforced Silica Tread Compound

摘要

The present invention relates to a silica- silane coupling agent and the silica -reinforced rubber composition , more particularly to induce dispersion of the silica mounds minimize energy consumption and relates to a rubber composition which can maintain a high temperature silica- stability ; this invention is a solution polymerization styrene- butadiene rubber or a solution polymerized styrene-butadiene rubber and butadiene in the rubber mixture of the rubber to the silica in the rubber composition of the raw material rubber , the BET value of the raw material with respect to 100 parts by weight of rubber 130~200 / g with respect to 40 to 90 parts by weight of the precipitated silica with the silica of 4-11 % by weight silane coupling silica and a silane coupling agent characterized by containing the agent provides the silica reinforced rubber composition .
