RESIN COMPOSITION FOR VIBRATION-DAMPING MATERIAL

Title:

RESIN COMPOSITION FOR VIBRATION-DAMPING MATERIAL

Document Type and Number:

WIPO Patent Application WO/2020/032022

Kind Code:

A1

Abstract:

The present invention provides a method for obtaining a coating film that has excellent water resistance, and can sufficiently maintain superior vibration-damping properties even under high temperature and high humidity conditions. The present invention pertains to: a resin composition that is for a vibration-damping material and that contains a surfactant component having a secondary alcohol ethoxylate backbone, and a resin having a weight-average molecular weight of 60,000-350,000; a vibration-damping coating material containing the resin composition for a vibration-damping material, and a pigment; a coating film obtained using the vibration-damping coating material; and a vehicle having the coating film. The present invention also pertains to a production method that is for a resin composition for a vibration-damping material and that comprises a step for conducting emulsion polymerization of monomer components in the presence of a surfactant having a secondary alcohol ethoxylate backbone to obtain emulsion resin particles having a weight-average molecular weight of 60,000-350,000.
