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 an 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.
