Problems solved by technology

[0002] Ordinary walls have poor stain resistance and are prone to rain marks, cracks, blooms, chalking, peeling, and mildew on the walls, which affect the appearance of homes and cities. People usually use topcoats to improve the above problems. Environmentally friendly high-performance exterior wall coatings should be the main development direction for exterior wall decoration materials in my country, among which fluorocarbon paint is a better choice, but the existing fluorocarbon wall paints are not strong in stain resistance and solvent resistance , water and flame retardant, poor aging resistance, poor mildew and moisture resistance, high surface tension of the paint film, volatile gas will be emitted, not safe and environmentally friendly
Although the application number is: CN201710882119.X discloses a stain-resistant fluorocarbon wall paint and its preparation method, which improves the above problems to a certain extent, but there are still some performance shortcomings in actual use that need further enhancement

Abstract

The invention discloses a preparation method of a fluorocarbon paint for a building wall surface, wherein the fluorocarbon paint comprises a component A and a component B. The preparation method of the component A comprises: jointly adding a fluorocarbon resin, a urea formaldehyde resin and an enhanced flame retardant into a stirring tank, carrying out first stirring for 20-25 min, adding nanometer titanium dioxide, sodium pyrophosphate, a leveling agent, a dispersing agent and an antifoaming agent into the stirring tank, carrying out second stirring for 1-1.5 h, adding a curing agent into thestirring tank, stirring for 10-15 min, and taking out. The preparation method of the component B comprises: putting a fluorocarbon resin, an acrylic resin, vinyl trimethylsiloxane, isocyanate, ethylacetate, dodecanol ester, ethylene glycol monobutyl ether, nonylphenol polyoxyethylene ether and deionized water into a reaction kettle together, heating to keep the temperature in the reaction kettleat 35-40 DEG C, continuously stirring for 2-3 h, and taking out. According to the invention, the preparation method is simple in overall process, reasonable in selection and matching of all the components and easy to use and manufacture.
