Anti-fog glass and preparation method thereof

Abstract

The invention discloses an anti-fog glass and a preparation method thereof, wherein the anti-fog glass comprises a hydroxylated glass substrate, a cross-linking layer, an anti-fog layer, and a protection layer prepared by a hydrogel solvent replacement method. According to the present invention, the anti-fogging performance test results show that the anti-fog glass of the present invention has significant anti-fogging effect, and cannot produce fog for a long time compared with the untreated glass substrate; and the light transmittance test results show that the anti-fog coating has little effect on the light transmittance of the glass product, and even the sample coated with the multiple anti-fog coatings can still maintain a light transmittance of more than 90%.

Description

technical field [0001] The invention relates to the technical field of anti-fog glass, in particular to an anti-fog glass and a preparation method thereof. Background technique [0002] Atomization of glass refers to the fact that water vapor in the air reaches saturation when cooled to its dew point, and condenses on the surface of glass products to form tiny droplets. These droplets refract and scatter light, resulting in the opacity of glass. The fogging of building glass windows, bathroom mirrors, and glasses will bring a lot of inconvenience to life, and the fogging of car windshields will seriously endanger driving safety. [0003] Anti-fog glass refers to the special physical or chemical treatment of ordinary glass to produce unique physical and chemical properties on the surface to prevent the surface of the glass from fogging, so as to achieve the effect of not affecting the visibility of the mirror image or the light transmittance of the glass. The preparation met...
