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 of my country's exterior wall finishing materials, among which fluorocarbon paint is a better choice, but the existing fluorocarbon wall paint has enhanced anti-fouling and solvent resistance. , Water and alkali resistance, poor aging resistance, poor mildew and moisture resistance, high surface tension of the paint film, will emit volatile gas, not safe and environmentally friendly, therefore, further research is needed to solve the above problems

Abstract

The invention belongs to the technical field of fluorocarbon wall finish, in particular to a stain-resistant fluorocarbon wall finish and a preparation method thereof. The stain-resistant fluorocarbon wall finish comprises a deionized water, a dispersing agent, a wetting agent, a defoaming agent, antiseptic, propylene glycol, rutile titanium dioxide, fluorocarbon emulsion, film forming additive, a polyurethane thickening agent and a polyurethane leveling agent. Compared with the prior art, the stain-resistant fluorocarbon wall finish and the preparation method thereof have the advantages that since raw materials for preparing the fluorocarbon emulsion and reaction conditions are in strict control, copolymerization conversion rate is high and hydrophobicity of the fluorocarbon emulsion is enhanced; adhesive force of the fluorocarbon wall finish is improved by cooperation of other additives in corresponding weight effectively, the fluorocarbon wall finish has ultra-low surface energy and weak hydroscopicity on the basis of the corresponding preparation method, and accordingly can resist stain effectively and is easy to clean and maintain; besides, the fluorocarbon wall finish has high gloss retention and color retention, and accordingly realizes decoration and protection to wall surfaces and prolong service life of buildings.
