Ultra-high transparency single silver low-e coated glass that can be tempered in different places

Abstract

The invention discloses ultrahigh-transparency single-silver Low-E film plated glass capable of being tempered at different places. According to the ultrahigh-transparency single-silver Low-E film plated glass, a first medium layer, a second medium layer, an Ag layer, a stopping layer, a third medium layer and a fourth medium layer are sequentially arranged outwards from substrate glass, wherein the first medium layer is made of ZnSnOx; the second medium layer is made of ZnAlOx; the stopping layer is made of Ti; the third medium layer is made of ZnAlOx; and the fourth medium layer is made of TiOx. The ultrahigh-transparency single-silver Low-E film has relatively high visible light transmittance and can keep relatively good energy-saving effect. The product is stable, the anti-scratching capability is strong and the machinable property is excellent.

Description

technical field [0001] The invention relates to an ultra-high transparent single-silver Low-E coated glass that can be toughened in different places. Background technique [0002] In the film system design of conventional offline low-emissivity coated glass, NiCr alloy is generally used as the protective layer and light attenuation layer of the silver layer of the functional layer. This alloy material has a certain attenuation effect on visible light and cannot produce ultra-high transmittance and low-emissivity coated glass. (Low-E for short), the visible light transmittance of a single piece of low-emissivity coated glass produced by using this alloy material generally does not exceed 80%, and there is no way for ultra-high transmittance Low-E with a light transmittance greater than 80%. However, after the light transmittance of some products barely reaches 80%, the scratch resistance of the product is poor, the adhesion of the film layer is not firm, and the product canno...

[0002] In the film system design of conventional offline low-emissivity coated glass, NiCr alloy is generally used as the protective layer and light attenuation layer of the silver layer of the functional layer. This alloy material has a certain attenuation effect on visible light and cannot produce ultra-high transmittance and low-emissivity coated glass. (Low-E for short), the visible light transmittance of a single piece of low-emissivity coated glass produced by using this alloy material generally does not exceed 80%, and there is no way for ultra-high transmittance Low-E with a light transmittance greater than 80%. However, after the light transmittance of some products barely reaches 80%, the scratch resistance of the product is poor, the adhesion of the film layer is not firm, and the product cannot be heat treated (commonly known as tempering), which is not conducive to subsequent processing
