摘要
PROBLEM TO BE SOLVED: To provide a rubber composition for a seismically isolated structure, which when formed into vulcanized rubber, exhibits excellent attenuation performance, large deformation characteristic, hysteresis dependency and temperature dependency.;SOLUTION: The rubber composition for seismically isolated structure is provided that contains: 5 to 50 pts.wt. of an alicyclic hydrocarbon resin; and 5 to 60 pts.wt. of a polyester polyol oligomer which is a condensate of aromatic polyvalent carboxylic acid and aliphatic polyhydric alcohol, with respect to 100 pts.wt. of a rubber component containing a butadiene rubber. The polyester polyol oligomer is preferably one having a viscosity of 100 to 20000 (mPa s, 75°C).;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
