Abstract

The device disclosed by the invention comprises (from glass substrate outward) glass / dielectric layer / silver layer / protection layer / composite dielectric layer / silver layer / protection layer / dielectric layer, wherein the dielectric layer being SnO2, sputtered in oxygen-argon atmosphere through the tin target of the AC cathode, the silver layer being Ag, sputtered in argon atmosphere through the DC flat target, the protection layer being NiCr, sputtering nickel-chromium alloy in argon atmosphere through the DC flat target.

Description

technical field [0001] The invention is a kind of low radiation coated glass coated with double silver layer and compound dielectric layer. Background technique [0002] There are many kinds of low-emissivity coated glass with multi-layer coating on the market, but there is no coated glass coated with double-layer silver with high visible light transmission. Contents of the invention [0003] A multi-layer film layer is plated on the glass substrate. The film structure of each layer, from the glass substrate to the outside, is as follows: [0004] Glass / dielectric layer (1) / silver layer (1) / protective layer (1) / composite dielectric layer (1) / silver layer (2) / protective layer (2) / dielectric layer (2); [0005] Among them: the dielectric layer (1) is SnO 2 ; [0006] The silver layers (1), (2) are Ag; [0007] The protective layers (1), (2) are NiCr; [0008] The composite dielectric layer (1) is TiO x / SnO 2 / TiO x structure; [0009] The dielectric layer (2) is Si...
