Abstract

The invention discloses a self-cleaning coating applied to doors and windows, and a preparation method thereof. The coating comprises a modified polyurethane monomer dispersion, nanometer titanium dioxide, nanometer zinc oxide, a coupling agent, a leveling agent, a solvent, a film-forming agent, a co-emulsifier, an emulsifier and an initiator. The modified polyurethane monomer dispersion is obtained by adding polyether glycol, carboxyl-containing semi-ester glycol and butyl acrylate into a dispersion machine according to the weight ratio of (5-7): (1-2): 1, and stirring for 20-45 min at the rotating speed of 1000-1500r / min for reaction. The prepared coating not only has a remarkable self-cleaning effect, but also has a synergistic effect with nanometer zinc dioxide when applied to an aluminum plate, the anti-pollution and anti-corrosion capabilities of the coating are improved, and when applied to the self-cleaning door and window aluminum plate for a long time, the coating is not prone to color change and falling off after, and the problems that the surface of an object is rusted and corroded and the like are avoided.

Description

technical field [0001] The invention relates to the preparation of self-cleaning materials, in particular to a self-cleaning coating applied to doors and windows and a preparation method thereof. Background technique [0002] The development of self-cleaning materials is mainly by coating a layer of coating with self-cleaning performance and anti-reflection effect on the surface of the substrate, and titanium dioxide is commonly used in such self-cleaning coatings, and its surface can use sunlight and natural It uses rainfall to keep itself clean, which can save maintenance time, cost and energy, purify the air and reduce environmental pollution. Titanium dioxide has a wide range of applications in high-tech fields such as photocatalysis, sensors, solar cells, and biomaterials. Under the irradiation of light, titanium dioxide has functions such as superhydrophilicity, photocatalysis (decomposition of organic matter), and release of negative oxygen ions, that is to say, tita...
