摘要:
Provided is a vibration damping material, which includes a resin composition obtained by dispersing titanium dioxide (Y) and a mica flake (Z) in a polyester resin (X) containing dicarboxylic acid constitutional units and diol constitutional units, in which: (1) in the polyester resin (X), a ratio of a total of a number of the dicarboxylic acid constitutional units (A1) having an odd number of carbon atoms in a main chain and a number of the diol constitutional units (B1) having an odd number of carbon atoms in a main chain with respect to a total of a number of total dicarboxylic acid constitutional units (A0) and a number of total diol constitutional units (B0), i.e., [(A1+B1)/(A0+B0)] is in a range of 0.5, to 1; and (2) a mass ratio (X:Y:Z) of the polyester resin (X), the titanium dioxide (Y), and the mica flake (Z) is in a range of 15 to 40:5 to 30:30 to 80. The vibration damping material is light, has a high vibration damping ability, and exhibits a higher vibration damping ability in a particularly wide range of frequency. Because the vibration damping material does not require use of a carbon powder or the like, the material can also be used in applications and parts that require various color tones, and has high versatility. Therefore, the vibration damping material can be widely used in parts, where vibration occurs, in a vehicle, a railway car, an aircraft, a household appliance, an OA apparatus, a precision apparatus, a building machine, a construction/building, shoes, a sport gear, and the like.
