Problems solved by technology

[0002] In the field of using glass such as glass panels of electronic display devices, solar cell packaging glass covers, showcases, photo frames, and window glass of locomotives and ships, ordinary glass itself has 8% of reflected light, which often produces glare in general environments. People's vision produces fatigue; in addition, dust and oil in the air, as well as fingerprints produced when hands touch the glass, make the glass unclear and cause visual fatigue

Abstract

The invention provides a piece of coated glass with dual functions of visible light antireflection and oil resistance, and a preparation method thereof. The piece of coated glass adopts a film structure comprising a glass substrate, a base layer film, a transitional layer film and a surface layer film in sequence, wherein the base layer film is a silicon compound film, the transitional layer film is a silicon-fluorine compound film, and the surface layer film is a silicon-fluorine organic compound film; the overall thickness of the film structure is 90-140 nm; the film is formed in the optical glass through a roll coating method by the base layer and through a spray method by the transition layer and the surface layer; the transmissivity of the coated glass in spectral wavelength range of 380-1,100 nm is improved by 2.5-3.5 percent; the film rigidity is 3.0-4.5 H; and the water-wetting angle is 105-142 degrees. The coated glass provided by the invention can be used for electronic display glass panels, encapsulation glass cover plates, shop windows, photo frames, locomotives and ship window glass, and other fields where the glass is used, and has the advantages of oil resistance and dazzling light prevention.

Description

technical field [0001] The invention specifically relates to a visible light anti-reflection and anti-oil dual-function coated glass and a preparation method thereof. It belongs to the field of glass used for electronic display device glass panels, solar cell packaging glass cover plates, showcases, picture frames, and window glass for locomotives and ships. Background technique [0002] In the field of using glass such as glass panels of electronic display devices, solar cell packaging glass covers, showcases, photo frames, and window glass of locomotives and ships, ordinary glass itself has 8% of reflected light, which often produces glare in general environments, making People's vision produces fatigue; in addition, dust and oil in the air, as well as fingerprints produced when hands touch the glass, make the glass unclear and cause visual fatigue. In order to overcome glare, reduce pollution and fingerprints, and reduce visual fatigue, glass is required to resist oil st...
