Water-based quick-drying silver powder paint and preparation method thereof

Abstract

The invention relates to the technical field of coatings, and particularly discloses a water-based quick-drying silver powder paint and a preparation method thereof. The water-based quick-drying silver powder paint comprises the following components in percentage by mass: 40 to 45% of a water-based fluorocarbon self-crosslinked acrylic emulsion; 20-25% of an aliphatic polyurethane resin dispersion, 0.1-0.2% of an antifoaming agent, 0.3-0.5% of a dispersant, 0.3-0.5% of a leveling wetting agent, 1-2% of an anti-flash rust agent, 1-2% of a pH regulator, 5-7% of a coalescing agent, 0.5-1% of an anti-oil agent, 4-8% of aluminum powder and the balance deionized water. The difference between the surface drying speed and the hard drying speed of the water-based quick-drying silver powder paint isnot large, aluminum powder in paint films can be directionally and evenly arranged, high salt spray resistance and water resistance are achieved, and the water-based quick-drying silver powder painthas good use performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based quick-drying silver powder paint and a preparation method thereof. Background technique [0002] Silver powder paint is a paint-like substance obtained by adding aluminum powder to the paint after dilution. Silver powder paint is mostly used on some water pipes and other pipes in old-fashioned buildings. Because it has a good flash effect, it also has excellent corrosion resistance. Water resistance, temperature resistance and anti-rust ability, so the current silver powder paint is widely used in some heating equipment, vehicles, metal pipes, and some other metal surfaces that need anti-corrosion. [0003] The volatilization of the solvent in the silver powder paint can shrink the paint film, and finally press the aluminum pigment into a horizontal orientation position. When the aluminum powder and the paint film are oriented in parallel, the best effect can be ac...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems that the existing silver powder paint has a large gap between surface drying and actual drying speed, which affects the directional arrangement of aluminum flakes, forms cavities on the surface of the paint film, and affects the appearance of the paint film and the performance of salt spray resistance, the present invention provides a water-based fast Dry silver powder paint and preparation method thereof
