Abstract

Aiming at solving the technical problem that the indoor heat insulation function is reduced because a silver layer is easy to oxidize when silver layer glass is adopted in the prior art.
Description
Technical Field
The invention relates to the technical field of glass, in particular to coated glass and a preparation method thereof.
Background
Low-emissivity coated glass, also called Low-E glass, is a film product formed by coating multiple layers of metals or other compounds including silver layers on the surface of the glass. Because the silver layer has the characteristic of low radiation, the low-radiation glass has higher transmissivity to visible light, has higher reflectivity to infrared rays and has good heat-insulating property.
The film structure of the Low-E glass produced by the vacuum magnetron sputtering method is generally as follows: glass substrate/base dielectric layer/base barrier layer/functional silver layer/upper barrier layer/upper dielectric layer.
The dielectric layer is typically a metal oxide or nitride, a non-metal oxide or nitride, such as TiO2、ZnSnOx、SnO2、ZnO、SiO2、Si3N4And the like.
However, in the development and production of the traditional low-radiation film, the silver layer is oxidized and cannot be exposed in the air for a long time, and the film has timeliness even if being sealed and stored by a drying agent. The general low-radiation coated glass is used as the outdoor surface of the hollow glass, and the membrane is jointed in the hollow cavity, which results in great reduction of the indoor heat preservation effect.
Therefore, a low-emissivity coated glass which can replace indoor white glass or ultra-white glass and has the function of improving indoor heat insulation is needed.
