Problems solved by technology

[0002] Fluorocarbon coatings have been widely used in building exterior wall decoration and external thermal insulation decoration systems due to their super weather resistance, high decoration, chemical resistance, and stain resistance, especially fluorocarbon aluminum silver paste (pearl) coatings because of their comparative Low-cost, high-decorative and gradually replace the high-cost metal curtain wall, but because of the high VOC of solvent-based fluorocarbon aluminum paste (pearl) paint, it pollutes the environment, and in the external wall insulation system, due to the poor solvent resistance of the insulation material, Solvent-based coatings have a risk of damaging the insulation, limiting their use

Abstract

The invention relates to an environment-friendly aqueous fluorocarbon metallic paint, consisting of the following raw materials in the following percents by weight: 35-65 percent of fluorocarbon emulsion, 5-12 percent of aluminum paste, 0.1-0.5 percent of antifoam agent, 0.1-0.3 percent of wetting agent, 0.1-0.3 percent of leveling agent; 0.2-0.8 percent of dispersing agent, 2-8 percent of metal orienting agent, and 0.1-0.3 percent of thickener: organic modified montmorillonite, 1.0-5.0 percent of polyurethane associative thickening agent, 1-3 percent of film forming agent, 1-3 percent of anti-freezing agent, 6-10 percent of solvent, and deionized water as the rest. The environment-friendly aqueous fluorocarbon metallic paint can reduce environmental pollution and application risks in thermal-insulation decoration systems and the performance can equal to that of solvent-based fluorocarbon aluminum paste (pearl powder) coating.
