preparation example Construction

[0025] In the preparation method of the anti-fog glass provided by the present invention, the glass is activated first, and then the activated glass is coated with hydrogel, and the surface of the activated glass can be more easily and firmly bonded with the hydrogel. Combine, and then use glycerin to replace the solvent (ie water) in the hydrogel, thereby forming a gel-glycerin anti-fog film combined on the glass surface, which can effectively perform anti-fog effect for a long time.

[0026] In the step S1, glass is firstly provided, and the glass may be a mirror, spectacle lens, automobile reflector, window glass, optical instrument glass, etc. Considering that the glass surface is unclean due to dust or grease pollution, which is not conducive to the adhesion and bonding of hydrophilic hydrogels, it is necessary to clean and activate the glass before coating the hydrogels. Preferably, the plasma is used to treat the The glass is cleaned and activated, that is, the glass is...

Embodiment 1

[0036] Preparation of ammonium persulfate solution: Dissolve 0.01 g of ammonium persulfate in 1 mL of ultrapure water to obtain ammonium persulfate solution;

[0037] Prepare calcium sulfate solution: dissolve 0.032g calcium sulfate dihydrate in 6mL ultrapure water to obtain calcium sulfate solution;

[0038] Preparation of hydrogel: Add 0.5g sodium alginate and 4g acrylamide into 25mL ultrapure water, mix well, then take 15mL, add 60uL of the ammonium persulfate solution and 4mL of the calcium sulfate solution, mix to obtain Hydrogels;

[0039] Preparation of anti-fog glass: Treat the glass with plasma for 3 minutes in advance, then coat a layer of the hydrogel on the surface of the glass, and treat it under ultraviolet irradiation for 40 minutes to obtain the hydrogel-coated glass; The coated glass is completely soaked in glycerin for 3 hours, and then taken out to obtain the anti-fog glass;

Abstract

The invention discloses anti-fog glass and a manufacturing method thereof. The manufacturing method comprises the steps of providing glass, and activating the glass; coating the activated glass with hydrogel, and then conducting solidification to obtain hydrogel-coated glass; conducting a solvent-replacement reaction on the hydrogel in the hydrogel-coated glass by utilizing glycerin to obtain theanti-fog glass. The anti-fog glass and the manufacturing method thereof solve the problem that existing glass cannot continuously and effectively achieve fog prevention.

Description

technical field [0001] The invention relates to the field of anti-fog technology, in particular to an anti-fog glass and a manufacturing method thereof. Background technique [0002] At present, mirrors, glasses, car reflectors, windows, optical instruments, etc. are all indispensable objects in real life, which bring great convenience to people's life, but often due to changes in the temperature of the use environment, the glass surface Fog or frost is formed, which then interferes with the light path and light transmittance, which brings great troubles to our daily life. In order to solve this problem, anti-fog and anti-freeze methods have also been reported in the prior art literature, mainly by forming a layer of hydrophilic or hydrophobic polymer on the glass surface, but these methods have many shortcomings, such as: the duration is not long Long, poor adhesion, toxic, high cost, complicated process, etc. [0003] Therefore, the prior art still needs to be improved a...
