preparation example Construction

[0035] The invention provides a method for preparing the anti-fog coating. According to the difference in the number of layers of the cross-linked layer and the anti-fog layer, the preparation method is as follows:

[0036] When the anti-fog coating is composed of one layer of cross-linked layer and one layer of anti-fog layer, the preparation method of the anti-fog coating comprises the following steps: plate the cross-linked layer on the surface hydroxylated substrate, and carry out curing treatment ; Coating an anti-fog layer on the side of the cross-linked layer away from the substrate for curing.

[0037] When the anti-fog coating includes two or more cross-linked layers and two or more anti-fog layers, the preparation method of the anti-fog coating includes the following steps, step (1): plating the second layer on the surface hydroxylated substrate A cross-linked layer is subjected to curing treatment; the first anti-fog layer is coated on the side of the first cross-li...

Embodiment 1

[0045] This embodiment discloses an anti-fog coating composed of one layer of cross-linked layer and one layer of anti-fog layer. The preparation steps of anti-fog glass coated with the anti-fog coating are as follows:

[0046] (1) Hydroxylation of glass substrates: ultrasonically clean the clean glass substrates in deionized water, acetone, and deionized water for 5 minutes, 10 minutes, and 5 minutes, and rinse with a large amount of deionized water for several times; then place them in 30% H 2 o 2 with 98% concentrated H 2 SO 4 (1 / 3) was ultrasonically activated in the mixed solution for 30 minutes, washed with a large amount of deionized water until neutral; again ultrasonically cleaned in deionized water, acetone, and deionized water for 10 minutes, 5 minutes, and 5 minutes. The glass substrate was taken out, dried by nitrogen gas, and stored in vacuum at room temperature.

Abstract

The invention provides an antifogging coating, a preparation method of the antifogging coating and antifogging glass. The antifogging coating disclosed by the invention comprises at least one crosslinking layer and at least one antifogging layer, wherein the crosslinking layer and the antifogging layer are alternatively arranged to form the antifogging coating; the crosslinking layer plated on a base is arranged at one side of the antifogging coating; the antifogging layer is arranged at the other side. The antifogging coating has the advantages of being lasting in anti-fogging performance, and good in abrasive resistance, heat resistance and resistance to water solubility. The preparation method of the antifogging coating provided by the invention is scientific and reasonable in steps, simple and feasible in technology, low in cost and wide in application range. The antifogging glass provided by the invention has an excellent anti-fogging effect when the light transmittance is ensured.

Description

technical field [0001] The invention relates to nanometer material technology, in particular to an anti-fog coating, a preparation method of the anti-fog coating and anti-fog glass. 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 g...
