Coated glass capable of blocking ultraviolet light efficiently and preparation method

Abstract

The invention belongs to the technical field of preparation of energy-saving and environment-friendly coated glass and relates to coated glass capable of blocking ultraviolet light efficiently and a preparation method. The glass comprises a glass substrate and a TiNx film arranged on the surface of the glass substrate in a coated mode; x in the TiNx film is 0.9-1.1; the thickness of the TiNx film is 200-300 nm; for ultraviolet light with the wave band smaller than 380 nm, the blocking rate of the TiNx film reaches 99% or above; the TiNx film is golden. The mode that the surface of the glass substrate is coated with the TiNx film is adopted, blocking of the ultraviolet light with the wave band smaller than 380 nm is achieved through the TiNx film, the blocking rate reaches 99% or above, and harm, caused by the ultraviolet light, to the health of people inside a room and object aging are effectively avoided; meanwhile, the TiNx film is represented to be golden, and the decoration function of ordinary glass can be enriched.

Description

technical field [0001] The invention belongs to the technical field of preparation of energy-saving and environment-friendly coated glass, and relates to a high-efficiency ultraviolet-blocking coated glass and a preparation method thereof. Background technique [0002] Ordinary glass original sheet, because it is a kind of high light transmittance material, has a high transmittance in the ultraviolet light area. When it is used as architectural glass for houses or cars, ultraviolet rays will induce cancer and cause indoor objects to age Therefore, if the glass surface can be coated with a film that can block ultraviolet rays and can not affect the glass lighting, it can meet the requirements. [0003] At present, there are two types of UV-blocking glass on the market: one is to add some oxides that can absorb ultraviolet rays into the glass body, such as: TiO 2 or CeO 2 , because too much of such oxides cannot be introduced into the glass body, otherwise it will adversely ...

Problems solved by technology

[0003] At present, there are two types of UV-blocking glass on the market: one is to add some oxides that can absorb ultraviolet rays into the glass body, such as: TiO 2 or CeO 2 , because too much of such oxides cannot be introduced into the glass body, otherwise it will adversely affect the performance of the glass itself, and TiO 2 with CeO 2 This type of oxide itself has a general effect of blocking ultraviolet rays and cannot achieve the ideal effect of blocking ultraviolet rays; the other is to coat a layer of film that can absorb ultraviolet rays on the glass surface, and this type of film mainly includes inorganic or organic.

The inorganic type is mainly coated with a functional film that absorbs ultraviolet light on one side of its surface by coating or magnetron sputtering, such as: TiO 2 film or ZnO film, but the film prepared by this method has poor stability and high cost, which is not conducive to popularization and application, and the effect is not ideal; and for organic film, it is mainly adhered to the glass surface in the form of a film, although The effect is good, but with the prolongation of the use time, the film will fall off, and the organic film itself is easy to age, and the service life is short

At the same time, most of the organic films are toxic and have certain limitations in terms of safety.
