A kind of exterior wall water-based metallic paint with antirust function and preparation method thereof

Abstract

The invention provides water-based metallic paint with a rustproof function for outer wall painting. The water-based metallic paint comprises the following components in parts by weight: 40-60% of silicone resin emulsion, 1-2% of film-forming agent, 10-20% of pearl pigment, 0.5-1% of flash-rust inhibitor, 0.3-0.6% of dispersant, 0.2-0.4% of wetting agent, 0.2-0.5% of defoaming agent, 0.3-1.0% of thickener, 0-5% of extinction powder and 25-35% of deionized water, wherein the silicone resin emulsion is water dilution type pure silicone resin emulsion, and the flash-rust inhibitor is modified zinc chelate. The water-based metallic paint provided by the invention has the advantages that the pure silicone resin emulsion is used as a film-forming agent, and meanwhile, the modified zinc chelate is added to the metallic paint and serves as the flash-rust inhibitor, so that a paint film has a good rustproof property, good stain resistance weather resistance and a very good decoration effect on outer walls and prolongs the service life of the walls relatively well. The invention aslo provides a preparation method with the rustproof function for the outer walls.

Description

technical field [0001] The invention relates to an exterior wall paint, in particular to a water-based metallic paint suitable for exterior wall painting, and more particularly to a water-based metallic paint with antirust function suitable for exterior wall painting. The present invention also relates to a preparation method of the above-mentioned water-based metallic paint for exterior walls with antirust function. Background technique [0002] At present, the common exterior wall decoration materials include paint, tiles, glass curtain walls or aluminum-plastic panels. Ceramic tiles are high-temperature sintered products, and the raw materials are mainly clay. The production process consumes a lot of energy and clay resources, and is prone to accidents of tile falling off. Therefore, it has gradually withdrawn from the market. In recent years, glass curtain walls have also suffered from heavy weight and light pollution. , coupled with the high cost, the use is also great...
