Problems solved by technology

However, at present, many fluorocarbon wall paints have poor anti-fouling, poor solvent resistance, poor water and alkali resistance, poor aging resistance, poor mildew and moisture resistance, high surface tension of the paint film, and volatile gases, which are not safe and environmentally friendly. Solve or not completely solve these problems, especially the problem that the stains are difficult to remove after the wall is pasted indiscriminately and graffiti

Abstract

The invention discloses high-performance water-based fluorocarbon paint which comprises the following components in percentage by mass based on 100% in total: 50-80% of water-based fluorocarbon emulsion, 0.1-0.4% of siloxane crosslinking agent, 0.01-0.1% of surfactant, 0.2-0.5% of antifoaming agent, 0.2-0.5% of preservative, 2.0-4.0% of ethylene glycol, 2.0-5.5% of film forming aid, 0.05-0.3% of multifunctional auxiliary, 7.5-30% of titanium dioxide and the balance of water. According to the high-performance water-based fluorocarbon paint disclosed by the invention, through the improvement of the water-based fluorocarbon emulsion and in combination with the siloxane crosslinking agent and other related auxiliaries, the adhesion of the water-based fluorocarbon paint can be effectively improved; the improved fluorocarbon emulsion and the selected fluorine surfactant SURFLONS-386 promote each other; in combination with other related auxiliaries, the antifouling capacity of the water-based fluorocarbon paint can be effectively improved; by adopting the improved fluorocarbon emulsion, siloxane and fluorine surfactant SURFLONS-386 as main functional materials and in combination with the effects of the auxiliaries such as antifoaming agent, a preservative, ethylene glycol, a film forming aid, a multifunctional aid, titanium dioxide, water and the like, the prepared water-based fluorocarbon paint has the advantages of water and alkali resistance, strong solvent resistance, mildew and moisture prevention, high adhesion and good antifouling capacity.

Description

technical field [0001] The invention relates to the technology in the field of water-based paint, in particular to a high-performance water-based fluorocarbon paint. Background technique [0002] Ordinary walls have poor stain resistance, are prone to rain marks, and the walls are prone to cracking, blooming, powdering, peeling, and mildew. Many walls have problems such as pasting, graffiti, etc., which affect people's homes. The beauty of life and the city. People usually use top paint to improve the above problems. The main development direction of exterior wall decoration materials in my country should be environmentally friendly high-performance exterior wall coatings. Among high-performance exterior wall coatings, fluorocarbon paints should be the first choice. However, at present, many fluorocarbon wall paints have poor anti-fouling, poor solvent resistance, poor water and alkali resistance, poor aging resistance, poor mildew and moisture resistance, high surface tens...
