Embodiment Construction

[0028] The present invention will be further described below in combination with embodiments.

[0029] 1. Preparation of inorganic nanoparticles

[0030] Prepare methanol and water as a solvent in a mass ratio of 1:2, and mix tetraethoxysilane and the solvent in a constant temperature water bath at 40-90°C in a mass ratio of 1:2. After fully stirring, add the hydrochloric acid catalyst dropwise in 30 minutes. After 2 hours of heat preservation, the nano-sol was obtained.

[0031] 2. Preparation of water-based acrylic resin

[0032] Make acrylic acid, acrylamide and water into a monomer solution in a constant temperature water bath at 50-90°C in a mass ratio of 1:4.5. After fully stirring, add the ammonium persulfate solution dropwise for 2 hours, then raise the temperature by 2°C, and keep it for 1 hour. That is, a water-based acrylic resin was obtained.

[0033] 3. Preparation of organic-inorganic hybrid anti-icing hydrophilic surface coating

[0034] Basic formula (parts...

Abstract

The invention provides an organic-inorganic hybrid anti-freezing hydrophilic aluminum foil coating which comprises a face coating component and a bottom coating component. The face coating component is prepared from, by weight, 10-40 parts of waterborne acrylic resin, 10-20 parts of nanosol, 10-45 parts of sodium silicate, 1-3.5 parts of polyethylene glycol, 1-6 parts of silane coupling agent, 4-8 parts of solvent, 0.5-3 parts of surfactant, 0.5-1.5 parts of pH controlling agent and the balance deionized water, and the bottom coating component is prepared from, by weight, 40-65 parts of acrylic modified epoxy resin, 10-25 parts of inorganic salt solution, 0.1-1 part of auxiliaries, 1-4 parts of solvent, 0.5-2 parts of curing agent, 2-10 parts of pH controlling agent and the balance deionized water. The organic-inorganic hybrid anti-freezing hydrophilic aluminum foil coating has the advantages that prepared aluminum foil for an air conditioner has multiple practical functions, and the corrosion resistance, hydrophilia and freezing resistance can be met simultaneously; an inorganic-organic hybrid system is adopted by the face coating component, and a super-hydrophilic property is achieved; the organic-inorganic hybrid hydrophilic aluminum foil has the non-icing property at low temperature.

Description

【Technical field】 [0001] The invention relates to the technical field of anti-icing hydrophilic coatings, in particular to an organic-inorganic hybrid anti-icing hydrophilic coating. 【Background technique】 [0002] Anti-icing is mainly achieved by super-hydrophobic treatment on the surface of aluminum foil. In the organic-inorganic coating system in "A super weather-resistant, wear-resistant and anti-icing wind power blade coating and its preparation method" with the publication number CN103013316A, fluorocarbon resin and polyester resin are used as film-forming materials, supplemented by nano-fillers and A wear-resistant, weather-resistant, and anti-icing wind power blade coating prepared with a dispersant. In 2010, researchers at Harvard University in the United States developed a fluorine-containing super-hydrophobic nano-coating. Since the contact area between this material and water droplets is reduced, it can prevent the intrusion of water droplets, and its base is ex...
