Abstract
The invention provides a super-hydrophilic anti-fogging coating. The super-hydrophilic anti-fogging coating comprises 25-35% of modified acrylic emulsion, 6.8-10% of nano silicon dioxide, 25-30% of water, 5.6-8% of film-forming additives, 3.2-5% of dispersing agent, 5.5-7.5% of defoaming agent, 1-1.8% of levelling agent, 2.5-4.7% of titanium dioxide and 3.4-4.7% of surfactant, wherein the modified acrylic emulsion is obtained through emulsion polymerization of styrene, methyl acrylate, trimethyl silane, a vinyl monomer containing N atoms and polyvinyl alcohol. The super-hydrophilic anti-fogging coating has good adhesion, water resistance and continuous anti-fogging property, is environment-friendly and has low toxicity.
Description
technical field [0001] The invention relates to a superhydrophilic anti-fogging coating. Background technique [0002] During the use of transparent substrates such as glass, when there is a certain temperature difference between the two sides, the vapor pressure of water on the side with lower temperature is lower, and the water vapor gathers on the surface of the lower temperature side and condenses into tiny water droplets, resulting in Atomization phenomenon. Once fogging occurs on the surface of the base layer, it will refract and diffuse light and affect the visual effect, such as spectacle lenses, mirrors, windshields of vehicles, etc., which will bring great harm to traffic safety and personal safety. [0003] The use of traditional solvent-based coatings is increasingly restricted due to their high levels of volatile organic compounds (VOCs) and harmful air pollutants. Therefore, pollution-free water-based coatings are attracting more and more attention. Water-ba...
