Abstract

The invention relates to laminated and film-coated anti-reflection glass and a preparation method thereof. The laminated and film-coated anti-reflection glass is prepared from a glass substrate, and an isolation layer, an anti-dazzling light film layer and a visible light anti-reflection film layer which are arranged on the glass substrate, wherein the isolation layer is a silicon dioxide aerogel film; the anti-dazzling light film layer is a porous-structure film layer obtained by corroding tin oxide through utilizing acid; the visible light anti-reflection film layer is a fluorine-doped composite film layer of titanium dioxide, niobium oxide, zirconium oxide, tin oxide and zinc oxide. Lamination and film coating are adopted; especially, the isolation layer is designed to be the silicon dioxide aerogel film and light is subjected to diffuse reflection for a plurality of times through micro-pores in the isolation layer; the tin oxide porous-structure film layer is designed on the anti-dazzling light film layer and the visible light anti-reflection film layer is the fluorine-doped composite film layer, so that light reflection is reduced and emitted light is reduced to be 1 percent or lower; a new technical way is explored for the anti-reflection glass and is suitable for industrial application.

Description

technical field [0001] The invention relates to a coated glass, in particular to a low-radiation anti-reflection coated glass and a manufacturing method thereof. Background technique [0002] We all have the experience of being disturbed by glare in our daily life. In 1984, the Illuminating Engineering Society of North America defined glare as: the feeling of annoyance, discomfort or loss of visual performance caused by lighting far larger than the eyes can adapt to within the field of vision. It refers to the overflowing light that causes discomfort to the human body, which is serious light pollution. Glare is a visual condition, which is formed either due to improper brightness distribution, or too large a range of brightness changes, or extreme contrast in space and time, which causes discomfort or reduces the importance of observation. The ability of an object, or both phenomena at the same time. Glare can be caused by high-brightness light sources (lights, sunlight) ...
