Water-based colored paint coating material, preparation method and application thereof

The invention provides a water-based colored paint coating material, a preparation method and application thereof. The water-based colored paint coating material comprises the following components in parts by weight: 20.0-30.0 parts of water-based polyester resin; 5.0-8.0 parts of water-based acrylic resin; 1.5-3.5 parts of a neutralizing agent; 5.0-10.0 parts of a cosolvent; 20.0-33.0 parts of deionized water; 0.2-0.5 part of a leveling agent; 0.1-0.6 part of a substrate wetting agent; 0.3-0.7 part of a defoaming agent; 7.0-10.0 parts of amino resin; 1.0-2.0 parts of an adhesion promoter; and 16.0-25.0 parts of water-based color paste. According to the invention, the water-based colored paint disclosed by the invention has better environmental protection performance, is suitable for single-coating coating when being applied to the surface of electrophoretic paint of a tricycle, can be constructed in an environment of 5-50 DEG C without preheating, and does not generate paint film defects such as edge flowing
