RUBBER COMPOSITION FOR ANTI-SEISMIC LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition for an anti-seismic laminate showing little temperature dependence of shear modulus thereby having stable shear modulus through a year while excellent mechanical and damping properties are held. SOLUTION: The rubber composition for the anti-seismic laminate comprises (1) a diene-based rubber, (2) carbon black having a CTAB specific surface area of 120 to 220 (m2/g) and a ratio of the CTAB surface area (m2/g) to iodine adsorption amount (mg/g) of not more than 0.90 and (3) a terpene-based resin and/or an alicyclic saturated hydrocarbon resin having a softening point of 70 to 150°C wherein the content of the carbon black is 40 to 160 pts.mass and the content of the terpene-based resin and/or alicyclic saturated hydrocarbon resin is 1 to 60 pts.mass based on 100 pts.mass of the diene-based rubber.
