Problems solved by technology

The water-based coatings commonly used in the market, especially the high temperature resistance, cannot meet the market demand. The high temperature resistance on the market can only reach about 200 °C, and it will crack when it exceeds 200 °C. The weather resistance is also poor, and the anti-corrosion performance cannot be achieved. Breakthrough, not conducive to the development of industrial water-based coatings

Abstract

The invention discloses a high-temperature-resistant water-based fluorocarbon amino baking varnish and a preparation method thereof. The high-temperature-resistant water-based fluorocarbon amino baking varnish comprises the following components in parts by weight: 10 to 40 parts of fluorocarbon emulsion; 10 to 30 parts of organic silicon modified acrylic emulsion; 0.5-1 part of a water-based dispersing agent; 0.2 to 0.5 part of a water-based surfactant; 0.2-0.5 part of a water-based base material wetting agent, 0.5-3 parts of a pH regulator acid-base neutralizer, 0.1-0.5 part of a thickener, 0.5-1 part of an adhesion promoter, 1-5 parts of a rheological modified wax dispersion, 5-15 parts of amino resin, 12-40 parts of a high-temperature-resistant pigment filler and 10-25 parts of an environment-friendly solvent. The high-temperature-resistant water-based fluorocarbon amino baking varnish contains the fluorocarbon, organic silicon modified acrylic emulsion, amino resin and high-temperature-resistant pigment, a paint film formed by baking the baking varnish has certain hardness and flexibility, has excellent weather resistance, water resistance, acid resistance, alkali resistance and corrosion resistance, and can achieve better high-temperature resistance after hard drying.

Description

technical field [0001] The invention relates to a high-temperature-resistant water-based fluorocarbon amino baking varnish and a preparation method thereof, belonging to the field of coatings. Background technique [0002] With the development of industry, the requirements for functional coatings that meet the needs of the industry field are getting higher and higher. [0003] Paint is a chemical product made of resin and oil, which forms a protective film after being coated on the surface of the object, which isolates the surface of the object from the environmental medium, thereby protecting and decorating the object accordingly. Among them, according to different needs, coatings are used in construction, industrial protection and other fields. With the enhancement of people's awareness of environmental protection and the continuous improvement of coating requirements, it has the expected effect, weather resistance, high temperature resistance, good fullness and high hardn...
