PURPOSE: A vibration damping paint is provided, to make be sprayed easily, to improve the adhesive power to the metal surface and the formability, to widen the frequency range of vibration damping ability and to minimize the temperature dependence. CONSTITUTION: The vibration damping paint comprises at least one acryl emulsion with a glass transition temperature of -25 to 25 deg.C; a resin; a silane coupling agent; a poly(vinyl alcohol); and 50-55 wt% of an inorganic filler which has a distribution of particle size of 1-100 micrometers and whose void fraction is minimized. Preferably the inorganic filler comprises 30-32 wt% of CaCO3 which has a distribution of particle size of 1-20 micrometers and a mean particle size of 2 micrometers and 5 micrometers; 10-12 wt% of SiO2 which has a distribution of particle size of 1-10 micrometers and a mean particle size of 4 micrometers; 10-12 wt% of mica which has a distribution of particle size of 1-100 micrometers and a mean particle size of 20 micrometers; and 5-10 wt% of aluminum oxide which has a distribution of particle size of 1-100 micrometers and a mean particle size of 15 micrometers. |
