Coated glass and preparation method thereof

Abstract

The invention discloses coated glass. The coated glass comprises a glass substrate and a film layer arranged on one surface of the glass substrate, wherein the film layer is sequentially provided with a first composite layer, a first functional layer, a second composite layer, a second functional layer, a protective layer, a discoloring layer and an antipollution layer from the glass substrate outward, the invention also discloses a preparation method of the coated glass, and the coated glass is mainly prepared by adopting a vacuum magnetron sputtering method. The coated glass prepared by adopting the preparation method has multiple functions such as pollution prevention, antioxidation, discoloration and thermal insulation.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a coated glass and a preparation method thereof. Background technique [0002] Glass is an important building material. With the continuous improvement of decorative requirements for buildings, the use of glass in the construction industry is also increasing. However, when people choose glass doors and windows for buildings today, in addition to considering their aesthetic and appearance features, they pay more attention to issues such as thermal control, cooling costs, and the comfortable balance of internal sunlight projection. This makes the upstart in the coated glass family - Low-E glass stand out and become the focus of attention. Low-E glass, also known as low-emissivity glass, is a film system product composed of multiple layers of metal or other compounds coated on the glass surface. Its coating layer has the characteristics of high transmittance to visible...

AI Technical Summary

Problems solved by technology

[0004] (1) Most of them do not have anti-fouling function, and the glass curtain wall in the air environment often becomes dirty quickly under the condition of environmental pollution. Because the glass area is large and the building is high, it takes a lot of manpower and material resources to clean the glass cost;

[0005] (2) It does not have anti-oxidation function. The Ag layer often loses its protective function due to the long-term oxidation of air and water, which reduces the anti-radiation effect of the glass;

[0006] (3) It does not have the function of discoloration, and the glass is prone to light pollution under strong light;

[0007] (4) Does not have heat insulation function or poor heat insulation effect
