  • Patent number: 5800888
    Abstract: The present invention relates to a heat-bonded type vibration-damping resin for a structural member which contains in view of a preferable blending rate asphalt, synthetic rubber, petroleum resin and filler material, and further a heat-bonded type vibration-damping resin for a structural member which contains in view of a preferable blending rate asphalt, filler material, blowing agent. In addition, its basic concept consists in a configuration in which the vibration-damping resin is formed into a sheet and arranged at the surface of the metallic structure used at a place where vibration and noise should be prevented so as to form the vibration-damping structure and a method for manufacturing the vibration-damping structure. The vibration-damping resin can be easily mounted on the surface of the metallic structure having an elongated shape, bonded to it by heating and has a workability in which the mounting work to the metallic plate may be facilitated.
