Resin emulsion for damping paint, damping paint, and method for producing resin emulsion for damping paint

摘要

Disclosed is a resin emulsion for a vibration-damping coating material that can contribute to the formation of a coating film that is unlikely to swell and peel off and that has good mechanical stability. An emulsion for a vibration-damping coating containing (meth) acrylic resin particles including an adsorption protective layer in which a polycarboxylic acid polymer compound is adsorbed on the particle surface. The ratio DA / DB of the average particle diameter DA by the laser diffraction / scattering method and the average particle diameter DB by the dynamic light scattering method of the (meth) acrylic resin particles is less than 1.
