Abstract
A vibration-damping sheet to be bonded to a metal adherend includes a resin layer and a constraining layer laminated on the resin layer. The resin layer contains a pressure-sensitive adhesive resin, a metal which has a higher ionization tendency than that of the metal adherend, and an electrically-conductive carbon.
Claims7
A vibration-damping sheet to be bonded to a metal adherend comprising:
- a resin layer and
- a constraining layer laminated on the resin layer, wherein
- the resin layer contains a pressure-sensitive adhesive resin, a metal which has a higher ionization tendency than that of the metal adherend, and an electrically-conductive carbon.
A method for damping vibration comprising:
- bonding a vibration-damping sheet to a metal adherend, wherein
- the vibration-damping sheet comprises:
- a resin layer and
- a constraining layer laminated on the resin layer, and
- the resin layer contains a pressure-sensitive adhesive resin, a metal which has a higher ionization tendency than that of the metal adherend, and an electrically-conductive carbon.
