COMPOUND TYPE MAGNETIC VIBRATION DAMPING MATERIAL
PROBLEM TO BE SOLVED: To provide a compound type magnetic vibration damping material which presents adsorption power stronger than the prior arts.SOLUTION: [1] The present invention relates to a compound type magnetic vibration damping material 10 which successively comprises a restriction layer 1, a viscoelastic layer 2, a high permeability layer 3 and a magnetic layer 4 and is adsorbed on a deposition surface by a magnetic force of the magnetic layer. [2] In the compound type magnetic vibration damping material, the high permeability layer consists of a magnetic material. [3] The compound type magnetic vibration damping material has adsorption power equal to or stronger than 50 g/cmto the deposition surface in the case where iron is disposed in depth of 0.55 mm to 0.65 mm from the deposition surface. [4] In the case where iron is disposed in depth of 0 mm to 1.0 mm from the deposition surface, in the compound type magnetic vibration damping material, a ratio of a mass (unit mass) of the compound type magnetic vibration damping material per unit area of the magnetic layer and the adsorption power of the compound type magnetic vibration damping material to the deposition surface (adsorption power/unit mass) is equal to or more than 6.SELECTED DRAWING: Figure 1
【課題】従来よりも強力な吸着力を発揮する複合型磁性制振材を提供する。【解決手段】［１］拘束層１、粘弾性層２、高透磁率層３及び磁性層４をこの順で備え、前記磁性層の磁力により被着面に吸着する複合型磁性制振材１０。［２］前記高透磁率層が磁性材料からなる上記複合型磁性制振材。［３］前記被着面が非磁性材料からなり、前記被着面から０．５５ｍｍ〜０．６５ｍｍの深さに鉄材が配置されている場合において、前記被着面に対して５０ｇ／ｃｍ２以上の吸着力を有する上記複合型磁性制振材。［４］前記被着面から０ｍｍ〜１．０ｍｍの深さに鉄材が配置されている場合において、前記磁性層の単位面積あたりの前記複合型磁性制振材の質量（単位質量）と、前記被着面に対する前記複合型磁性制振材の吸着力との比（吸着力／単位質量）が６以上である上記複合型磁性制振材。【選択図】図１
