Abstract

The invention discloses a method for using a solvent type resin aluminum pigment in a water paint. The method is characterized by comprising the following two steps: (1) making aluminum pigment dispersed slurry by using an epoxy phosphate resin having phosphate radicals and hydroxyl radicals; and (2) adding the obtained aluminum pigment dispersed slurry into a water paint base stock to obtain a water-based aluminum paint. The operation process of the method is simple and stable, the obtained product has high storage stability, and the water-based aluminum paint avoids negative effects on the performance of coatings and solves the problem that the water paint available on the market is too expensive.

Description

technical field [0001] The present invention relates to the paint industry in the field of chemical industry, in particular, to a method for using aluminum pigments for solvent-based resins in water-based paints, and more specifically, to a simple surface treatment technology and treatment of aluminum pigments The application method of post-aluminum pigments in water-based coatings. Background technique [0002] Silver, whether it's liquid metallic or shiny, is a hue that can be seen everywhere in a variety of rich color effects. In order to be able to produce such silvery effects, aluminum pigments are usually used. What makes aluminum pigment an effective pigment is that it has a unique metallic luster and strong covering power. Due to the characteristic hierarchical structure of this effective pigment, it can be oriented parallel to the substrate in the coating medium and thus generate many individual microscopic mirror surfaces, resulting in outstanding metallic effect...
