Problems solved by technology

[0004] Nowadays, in the production of off-line low-emissivity coated glass, most of them use pure silver as the functional film layer to reflect infrared rays. Because pure metal silver is easy to react with sulfide gas in the air, the performance of silver will be degraded, and silver will be easily oxidized and lost during high temperature heat treatment. Low-emissivity function, therefore, the current production of low-emissivity coated glass uses a multi-layer dielectric layer to protect the silver layer, and many low-emissivity coatings have great changes in performance after high-temperature heat treatment

Abstract

The invention discloses a film-coating product, in particular relates to film-coating glass capable of being performed with high-temperature thermal treatment. Materials for reflecting infrared film layers of the film-coating product is changed from traditional pure silver materials into alloy materials of silver and niobium, an Agl-aNba film layer deposited by the alloy materials of silver and niobium replaces a pure silver film layer to serve as a functional layer of the film-coating product, stability of films in high-temperature thermal treatment is improved, and simultaneously chemical stability of a silver layer is improved and mechanical performance of the silver layer is improved. The film-coating product has high visible light transmission rate, good mechanical resistance and chemical stability. The film-coating product is mainly used in automobile windshields.

Description

【Technical field】 [0001] The invention relates to a coated product, in particular to a coated glass capable of high temperature heat treatment. 【Background technique】 [0002] Ordinary glass has no heat insulation function. With the enhancement of people's awareness of energy saving, many buildings or cars now use low-emissivity coated glass or heat-reflective coated glass. These coated glasses can play a very good heat insulation effect, making the building Increased comfort inside the vehicle or in the vehicle. [0003] Chinese patent CN201020503119.8 discloses a single-silver low-emissivity glass. The single-silver low-emission glass uses an AgCu layer instead of the traditional pure silver film layer as the functional layer, so that the product has the characteristics of low reflectivity and low emissivity. The patent discloses that the copper-containing silver alloy used as the infrared reflection layer has a good infrared reflection function, but the copper contained ...
