ABSTRACT:
A vibration-damping material with excellent workability consisting of two metal plates and a vibration-damping layer of a thermoplastic resin interposed between the two metal plates, in which the vibration-damping layer of a thermoplastic resin consists of a film as a middle layer and a polyolefin type resin (B) provided on both sides of the film as an upper and lower layer, the film as the middle layer being composed of (1) at least one resin (A) selected from the group consisting of polyolefin type resins and ionomer resins each having a modulus of elasticity in shear at 20.degree. C. of 3.times.10.sup.9 to 1.times.10.sup.7 dyne/cm.sup.2, a percentage of elongation at 20.degree. C. of 50% or above and a peak temperature of dissipation factor (tan .delta.) of -120.degree. C. to 80.degree. C. or (2) a resin mixture of the resin (A) and a synthetic rubber having a percentage of elongation at 20.degree. C. of 100% or above and a peak temperature of dissipation factor (tan .delta.) of -120.degree. to 50.degree. C., and the polyolefin type resin (B) having a modulus of elasticity in shear at 20.degree. C. larger than that of the resin (A), a percentage of elongation at 20.degree. C. of 10% or above, a peak temperature of dissipation factor (tan .delta.) of -40.degree. to 180.degree. C. and a bonding strength toward the metal plates at 20.degree. C. and 180.degree. -peeling of 3 kg/cm or above.
