Color self-cleaning glass

Abstract

The invention relates to the field of environment-friendly energy-saving building materials, and discloses a color self-cleaning glass. The color self-cleaning glass adopts a three-layer structure comprising a medium layer 1 which is a self-cleaning coating and mainly made of titanium oxide, a medium layer 2 which is a specific-thickness coating, mixed from magnesium fluoride and yttrium oxide, coated through methods of electron beam evaporation, magnetron sputtering, PECVD or the like to enable glass to show various colors of blue, green, brick red, brown, purple, gray and the like, and a base layer which is plate glass or hot bending glass. The hot bending glass is accomplished for the first time through a film coating method, and a gap of the high-end building materials is filled up. The color of the glass can be adjusted simply and conveniently, various special colors and gradient color can be realized in small batch, the cost is low, the self-cleaning outer surface has good weatherability, and the color of the glass is durable.

Description

technical field [0001] The invention relates to a glass, in particular to a colored self-cleaning glass. Background technique [0002] Since the first discovery of the photocatalytic degradation of organic matter by titanium oxide in 1969, self-cleaning glass coated with titanium oxide has been extensively researched and developed. At present, there are hundreds of self-cleaning glasses being studied or applied, which can be divided into three categories in terms of production methods: magnetron sputtering, electron beam evaporation, and sol-gel methods; product functions It has also developed from the original single self-cleaning surface to multiple composite functions, such as low-radiation self-cleaning type, high antibacterial type, anti-reflection self-cleaning type and so on. [0003] Compared with uncoated glass, the existing ordinary self-cleaning glass products generally have lower light transmittance and higher reflectivity. If it is used in the cons...

AI Technical Summary

Problems solved by technology

Used in the construction field, it will lead to a decrease in transparency; used in the photovoltaic field, it will reduce the photoelectric conversion efficiency of the module

The newly-appeared anti-reflection self-cleaning glass improves the light transmittance while retaining the self-cleaning function, but generally has a high infrared transmittance, which is not enough for energy saving and environmental protection in the construction field.
