Problems solved by technology

[0004] Although water-based paints are environmentally friendly, metal powders are unstable in water and air, and often undergo chemical reactions and deteriorate. Therefore, special treatment is required on the surface, which makes the metal powders used in water-based paints expensive and limited in use. The current metal paint is mainly solvent-based

The invention further provides a preparation method of the resin dispersion liquid for the waterborne two-component metal paint. The resin dispersion liquid hasthe beneficial effects of good finished product stability and low production cost.

Description

technical field [0001] The invention belongs to the technical field of water-based paints, and in particular relates to a resin dispersion liquid for water-based two-component metal paints and a preparation method thereof. Background technique [0002] Metallic paint, also known as metallic flash paint, has fine metal powder (such as aluminum powder, copper powder, etc.) added to its paint base. After the light hits the metal powder, it is reflected through the air film. Therefore, it looks as if the metal is shining. This kind of metallic flash paint gives people a pleasant, light and novel feeling. Changing the shape and size of the metal powder can control the flash of the metallic flash paint film; on the outside of the metallic paint, a layer of varnish is usually added to enhance it. Protect. There are generally two types of metallic paints: water-based and solvent-based. With the pressure of environmental protection policies, consumers' awareness of environmental pr...
