In order to realize the above object, the utility model provides an antifog glass, antifog glass includes glass base member, transparent protection film and antifog coating, the thickness more than or equal to 3mm and less than or equal to 5mm of glass base member, the two surfaces of glass base member are provided with respectively transparent protection film, via nanotechnology in two the surface curing of transparent protection film forms antifog coating.

Compared with the prior art, the utility model provides an antifog glass, the antifog coating of its setting passes through nanotechnology and forms at the surface curing of transparent protection film, make to have super hydrophilic performance, and hydrophilic angle is below 5, the aqueous vapor can't form the drop of water this moment, the aqueous vapor spreads out on antifog coating surface uniformly, when the moisture content gathering on antifog coating surface reaches an amount, the moisture content flows down under certain gradient, also take away the dust on surface simultaneously, thereby reach the self-cleaning efficiency of glass, and then make glass base member surface keep transparent. And the transparent protective film arranged on the antifogging glass enables the glass matrix to play a good role in wear resistance and scratch resistance.

Preferably, the thickness of the antifogging coating is 20-60 mu m.

Preferably, the glass substrate is made of tempered glass. The glass substrate is toughened glass, makes the utility model discloses antifog glass's bending strength increase, difficult breakage.

Preferably, the transparent protective film is formed on the glass substrate by a vacuum magnetron sputtering coating process. The transparent protective film formed according to the vacuum magnetron sputtering coating process is thin and uniformly distributed, and the light transmittance of the antifogging glass is not influenced.

Preferably, antifog glass still includes silica gel vacuum ring, silica gel vacuum ring be respectively with encircle set up in the glass base member, transparent protection film and antifog coating around the outside. According to this structure, the silica gel vacuum ring not only makes the gas between glass base member, transparent protection film and the antifog coating three by the vacuum discharge, has improved the leakproofness, prevents moreover that antifog glass's surrounding outside from being destroyed.

Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

As shown in FIG. 1 and FIG. 2, the utility model provides a pair of antifog glass, antifog glass include glass base member 1, transparent protection film 2 and antifog coating 3, and the thickness more than or equal to 3mm and less than or equal to 5mm of glass base member 1, two surfaces of glass base member 1 are provided with transparent protection film 2 respectively, form antifog coating 3 in the surface curing of two transparent protection films 2 via nanotechnology. More specifically:

As shown in fig. 1 and fig. 2, the utility model provides an antifogging glass, which comprises a glass substrate 1, a transparent protective film 2 and an antifogging coating 3. Wherein, the thickness of the glass substrate 1 is more than or equal to 3mm and less than or equal to 5mm, and the glass substrate is suitable for shower rooms, kitchens, hospitals, laboratories, ships and the like. Transparent protection film 2 has two-layerly, and one of them in two transparent protection films 2 sets up in the surface of glass base member 1, and one of them another of two transparent protection films 2 sets up in another surface of glass base member 1, and the setting of transparent protection film 2 makes glass base member 1 can play fine wear-resisting anti-scratch effect. The antifogging coating 3 is formed by curing on the surface of the transparent protective film 2 through a nanotechnology, so that the antifogging coating has super-hydrophilic performance, the hydrophilic angle is below 5 degrees, water cannot form water drops at the moment, the water is uniformly spread on the surface of the antifogging coating 3, when the water on the surface of the antifogging coating 3 is gathered to a certain amount, the water slides downwards at a certain gradient, meanwhile, dust on the surface is also taken away, the self-cleaning effect of glass is achieved, and the surface of the glass substrate 1 is kept transparent.

Preferably, the thickness of the anti-fog coating 3 is 20 to 60 μm.

As shown in fig. 1 and 2, a transparent protective film 2 is formed on a glass substrate 1 by a vacuum magnetron sputtering coating process.
