Dual-function film coated glass capable of realizing anti-dazzle performance and visible light antireflection and preparation method of glass

Abstract

The invention provides dual-function film coated glass capable of realizing the anti-dazzle performance and the visible light antireflection and a preparation method of the glass. A film layer structure of the film coated glass is composed of a glass substrate, a separation layer, a concave-convex nano-micron compound hole structure film layer and a visible light antireflection film layer which are arrayed in sequence, and is obtained by coating a film by adopting a magnetron sputtering method and treating an anti-dazzle light film layer by adopting a weak acid corrosion method; the total thickness of the film layer is 145-270nm; in a spectral wavelength range of 380nm-1100nm, the transmittance of the dual-function film coated glass is increased by 2.5-4.5 when being compared with that of a glass raw sheet which is not coated with the film; the reflectivity is reduced by 3.5%-5.5% when being compared with that of the glass raw sheet (5%); the rigidity of the film layer is 5.0H-6.5H; the haze of the film coated glass is increased by 3.5-6.5% from 0.2% of the raw sheet. The obtained film coated glass can be used in fields of electronic display panels, packaging glass cover plates, showcases, lens frames, locomotives, steamship window glass and the like.

Description

technical field [0001] The invention belongs to the field of glass used for display device packaging glass cover plates, showcases, and window glasses of locomotives and ships, and specifically relates to a dual-function coated glass of anti-glare and visible light anti-reflection and a preparation method thereof. Background technique [0002] In the fields where glass is used as a window, such as electronic display device packaging glass cover and showcase, due to the 8% reflected light of ordinary glass itself and the strong light transmitted from the light-emitting device through the glass window, glare is often generated in the general environment. Make people's vision fatigue. In order to overcome glare and reduce visual fatigue, it is necessary to reduce or disperse the light intensity emitted by the display device and reduce the reflected light of the glass itself. [0003] According to the theory of thin film optics, the way to reduce the reflected light of glass is...

However, the disadvantage of this method is also extremely harmful. Hydrofluoric acid is a highly corrosive acid, which will cause great damage and pollution to the human body, the atmosphere, and the soil environment. The country strictly controls its use.
