EARTHQUAKE-PROOF DAMPER
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
【課題】低〜中歪みの長周期振動や、短周期振動に対し、高い減衰特性を示すとともに、上記減衰特性の温度依存性が低く、さらに変形後の回復性に優れる制震ダンパーの提供。【解決手段】二枚の金属板４，５に挟まれた粘弾性体２を備えた制振ダンパー１であって、上記粘弾性体２が、二種のスチレン共役ジエンブロック共重合体からなり、かつスチレン−ブタジエンジブロック成分量が６５重量％以上のスチレン−ブタジエン−スチレン共重合体を主たるポリマーとするゴム組成物からなる粘弾性体を構成部材とし、剪断歪み率２００％，周波数０．３３Ｈｚ，温度２０℃の条件下における上記粘弾性体の剪断弾性率を０．０５Ｎ／ｍｍ2以上とする。【選択図】図１
