A kind of multi-functional layer nitride low radiation energy-saving glass

Abstract

The present invention discloses multi-function layer nitride low radiation energy saving glass, the multi-function layer nitride low radiation energy saving glass includes a coated glass substrate (1), a depositing barrier layer for Na + ion barrier, a first functional layer, a second functional layer, a third functional layer and a protective layer are arranged sequentially from the inside to the outside on the coated glass substrate (1); the depositing barrier layer is a silicon nitride film layer (2); the first functional layer comprises three continuous film layers, namely an aluminum nitride layer (31), a titanium nitride film layer or a metal titanium film layer (32), and an aluminum nitride film layer (33); the second functional layer is a zirconium nitride film layer (41); the third functional layer is an aluminum nitride film layer (51), a titanium nitride film layer (52) and an aluminum nitride film layer (53); and the protective layer is a silicon nitride film layer (61). The multi-function layer nitride low radiation energy saving glass is good in weather resistance, good in corrosion resistance, good in mechanical properties, uniform in film layer distribution, softer in colors, and good in film density.

Description

technical field [0001] The invention relates to a coated energy-saving glass, in particular to a multi-functional nitride low-radiation energy-saving glass. Background technique [0002] With the requirements for energy saving and emission reduction in architectural glass and automotive glass, energy-saving glass has become one of the most important development directions. Single-layer or multi-layer films with selective photoelectric properties are sequentially deposited on the glass surface through offline or online technology. Layer, to achieve the effect of energy saving and emission reduction. Traditional low-emissivity energy-saving glass mostly adopts the film system of silver-based functional layer. Since metal silver is easy to oxidize, it will lose its photoelectric selective characteristics after oxidation. Therefore, the disadvantages of this type of energy-saving glass are mainly poor weather resistance and corrosion resistance. Setting up more isolation layers...

Problems solved by technology

Traditional low-emissivity energy-saving glass mostly adopts the film system of silver-based functional layer. Since metal silver is easy to oxidize, it will lose its photoelectric selective characteristics after oxidation. Therefore, the disadvantages of this type of energy-saving glass are mainly poor weather resistance and corrosion resistance. Set up more isolation layers and protective layers, thereby reducing the life of the glass product and increasing the production cost and the complexity of the film system
