MOLDING MATERIAL HAVING VIBRATION-DAMPING PROPERTY AND MOLDED ARTICLE

摘要

Provided is a molding material which comprises: a vibration-damping material (a) constituted of a resin composition obtained by dispersing titanium dioxide (Y) and mica flakes (Z) in a polyester resin (X) comprising dicarboxylic-acid-ingredient constituent units and diol-ingredient constituent units; and a modifier (ß) for improving flowability. The molding material satisfies that (1) in the polyester resin (X), the ratio of the total of the number (A1) of dicarboxylic-acid-ingredient constituent units in which the main chain has an odd number of carbon atoms and the number (B1) of diol-ingredient constituent units in which the main chain has an odd number of carbon atoms to the total of the number (A0) of all dicarboxylic-acid-ingredient constituent units and the number (B0) of all diol-ingredient constituent units, [(A1+B1)/(A0+B0)], is in the range of 0.5-1.0, (2) the mass ratio of the polyester resin (X) to the titanium dioxide (Y) to the mica flakes (Z) in the vibration-damping material (a), X:Y:Z, is (15-40):(5-30):(30-80), and the modifier is a specific material, e.g., a polypropylene resin. Also provided is a molded article of the molding material.
