Problems solved by technology

But the water-based finish varnish that is used for the finish of liquid marble paint also has deficiencies, for example: there are the deficiencies of slow drying at room temperature, low hardness and low gloss, and there is also poor water resistance itself, and its finish coat Most of them use water-resistant general finish varnishes. The composite coatings formed by them have poor water-whitening resistance and are prone to whitening after being washed by rain, which seriously affects the decorative effect and service life of the liquid marble paint finish.

Abstract

The invention discloses aqueous finishing vanish for liquid marble paint finishing. The aqueous finishing vanish is excellent in weather resistance, self cleaning property and waterproof whitening resistance, rapid to dry, high in hardness, good in gloss, excellent in durability and long in service life of a coated layer. The aqueous finishing vanish consists of a component M and a component N, wherein the component M consists of the following components in percentage by mass: 40-50% of an aqueous hydroxyl fluorocarbon emulsion, 20-30% of aqueous hydroxyl acrylic acid resin, 0.1-0.3% of a coupling agent, 0.15-0.35% of a stabilizer, 0.2-0.4% of a leveling agent, 0.2-0.4% of a defoaming agent, 0.1-0.2% of a drier, 0.2-0.5% of a substrate moistening agent and 50-70% of deionized water; and the component N consists of the following components in percentage by mass: 15-20% of a hydrophilic modified hexamethylene diisocyanate tripolymer solution, 0.1-1.0% of a corrosion and mildew preventive, 0.3-0.6% of an anti-freezing agent and 0.15-0.35% of a pH regulator.

Description

technical field [0001] The invention belongs to the technical field of paints for architectural decoration, in particular to a water-based finish varnish for liquid marble paint finishes. Background technique [0002] The finish varnish is a very important process in the paint coating process. Through the finish treatment of the paint, it can play a good role in protecting the underlying paint and improve the wear resistance, chemical resistance, weather resistance and scrub resistance of the paint. . However, for the water-based finish varnish, due to the presence of a large amount of surfactants in the formula, the water resistance and scrub resistance of the finish varnish are greatly reduced, which greatly affects the practical application performance of the water-based finish varnish. [0003] The so-called liquid marble paint belongs to imitation stone paint. Liquid marble paint has patterns and colors of high-grade decorative materials such as natural granite and rea...
