Problems solved by technology

[0003] At present, because most of the float glass used for coating is greenish, the overall color is greenish after coating, and the product transmission color is obviously green or yellow, which causes the outdoor reflection color to turn green or yellow, resulting in the transmission of light The rate is low, but as people continue to pursue visual quality, touch screen products with higher transmittance will have a larger market

Abstract

The invention discloses a method for producing LOW-E glass by means of vacuum magnetron sputtering. The method comprises the following steps that a cleaned and dried glass substrate is placed in a vacuum chamber of a magnetic control film coating machine; the vacuum degree in the vacuum chamber at least reaches 7.9*10<-6> mbar; the vacuum chamber is inflated with discharge medium gas, and the vacuum degree in the vacuum chamber reaches 2.8*10<-3> mbar-5.0*10<-3> mbar; in a straight argon or argon oxygen atmosphere, a ceramic TiOX base layer is formed on the glass substrate; in a straight argon atmosphere, a bottom blocking and protecting layer is formed on the ceramic TiOX base layer; in the straight argon atmosphere, a copper layer and a silver layer are sequentially deposited on the bottom blocking and protecting layer; in the straight argon atmosphere, a top blocking and protecting layer is formed on the silver layer; in the straight argon or argon oxygen atmosphere, a bottom dielectric layer is formed on the top blocking and protecting layer; in an argon oxygen atmosphere, a top dielectric layer is formed on the bottom dielectric layer.

Description

technical field [0001] The invention relates to coated glass, in particular to a method for producing LOW-E glass by vacuum magnetron sputtering. Background technique [0002] Low-E glass, also known as low-emissivity glass, is a film system product composed of multiple layers of metal or other compounds coated on the glass surface. Its coating layer has the characteristics of high transmission of visible light and high reflection of mid- and far-infrared rays, which makes it have excellent heat insulation effect and good light transmission compared with ordinary glass and traditional architectural coated glass. [0003] At present, because most of the float glass used for coating is greenish, the overall color is greenish after coating, and the product transmission color is obviously green or yellow, which causes the outdoor reflection color to turn green or yellow, resulting in the transmission of light The rate is low, but with people's constant pursuit of visual quality...
