摘要: A rubber composition for a tire contains a diene rubber, silica, a silane coupling agent, a fatty acid metal salt, and an alkylsilane. 60-95 mass % of a specific conjugated diene rubber is used as the diene rubber and is formed by reacting a polyorganosiloxane with an active terminal of a conjugated diene-based polymer chain having the active terminal and by making a polymer block A continuous with a polymer block B. The polymer block A contains 80-95 mass % of isoprene and 5-20 mass % of aromatic vinyl, has an active terminal, and has a weight average molecular weight of 500-15000. The polymer block B contains 1,3-butadiene and an aromatic vinyl and has an active terminal. 55-90 parts by mass of silica having a CTAB adsorption specific surface area of 185 m2/g or more is used as the silica.

摘要: An anti-vibration rubber composition contains: a polymer comprising component (A); and components (B) to (E). The mixing ratio of the components (B) and (C) is in a range of (B)/(C)=99/1 to 96/4 in weight ratio. As a result, it becomes possible to achieve a low dynamic magnification and to achieve both durability and weather resistance at a high level.
(A) diene rubber;
(B) silica;
(C) carbon black;
(D) silane coupling agent;
(E) dihydrazide compound represented by general formula (1).
[in general formula (1), R represents an alkylene group having 1 to 30 carbon atoms, a cycloalkylene group having 1 to 30 carbon atoms, or a phenylene group].-
