Title:
制震ダンパー
Document Type and Number:
Japanese Patent JP7190304
Kind Code:
B2
Abstract:
To provide an earthquake-proof damper exhibiting high attenuation characteristic to long period vibration of low to middle strain, or short period vibration, low in temperature dependency of the attenuation characteristic and further excellent in recoverability after deformation.SOLUTION: There is provided an earthquake-proof damper 1 having a viscoelastic body 2 sandwiched by two metal sheets 4 and 5, in which the viscoelastic body 2 has a viscoelastic body consisting of a rubber composition consisting of two kinds of styrene conjugated diene block copolymer, and containing a styrene-butadiene-styrene copolymer having styrene-butadiene block component amount of 65 wt.% or more as a main polymer, and shear elasticity of the viscoelastic body under a condition of shear strain rate of 200%, frequency of 0.33 Hz, and temperature of 20°C is 0.05 N/mmor more.SELECTED DRAWING: Figure 1
