Another object of the present invention is to provide a kind of antifog toughened glass.
Concrete technical scheme is as follows:
The antifog toughened glass that above-mentioned preparation method prepares.
Existing interactive intelligent tablet computer there will be big area water smoke in use after 30 minutes, affects product and normally watches.Its reason is as follows:
1, ambient moisture is larger: after ambient moisture is more than 80%, the glass of interactive intelligent tablet computer and display screen intermediate air will be very moist, when interactive intelligent tablet computer work is after 30 minutes, the temperature of machine intimate can rise, and glass belongs to non-hydrophilic material, moist gas will condense into the very little globule at glass surface, and the light of display screen will produce refraction, so see water smoke display screen just having one deck white through after these droplets;
2, glass internal-external temperature difference is large: particularly when summer, when product, when working, internal temperature can be higher, and indoor turn on the aircondition after envrionment temperature can decline, just increase with the temperature difference outside glass in product glass, the air of inside glass will form droplet and condenses in glass surface thus form water smoke.
Principle of the present invention and advantage as follows:
For the problems referred to above, the present invention according to hydrophilic principle, use acrylic resin as the antifogging agent of film forming material, spraying coating process and baking process is adopted to form the antifog rete of one deck on toughened glass surface, this rete has wetting ability, the contact angle of glass surface to water can be reduced, make the little water droplet condensed upon on surface not form tiny drops of water but open and filming at surface spreading, reduce light diffuse-reflectance.
Antifogging agent liquid medicine jet containing film forming material is coated in glass surface by antifog toughened glass of the present invention, again after the high bake of 200-300 DEG C, form the antifog rete of one deck at glass surface, hardness reaches 4-6H, rete is non-volatile, and cleaning glass also can not destroy rete.Automotive anti-mist glass of the prior art is that wetting ability liquid medicine jet is coated in glass surface, antifog rete can be formed after liquid solidifies, but this antifog rete antifog rete in the process of cleaning glass can be destroyed, and the rete after solidifying can volatilize, anti-fog effect being lost after 10-30 days, needing according to repeatedly spraying antifogging agent duration of service.
