Novel energy-saving toughened three-silver-layer low-radiation coated glass

Abstract

The invention provides novel energy-saving toughened three-silver-layer low-radiation coated glass, which is characterized in that: a film structure of the glass sequentially consists of the following layers from a glass substrate to the outside: the glass substrate, a first composite dielectric medium layer (11), a first reflection deduction layer (12), a first silver layer (13), a first protective layer (14), a second dielectric medium layer (21), a second reflection deduction layer (22) plus a second silver layer (23), a second protective layer (24), a third dielectric medium layer (31), a third reflection deduction layer (32), a third silver layer (33), a third protective layer (34), a fourth composite dielectric medium layer (35) and a fourth protective layer (36). The novel energy-saving toughened three-silver-layer low-radiation coated glass has the advantages that: an infrared reflection capacity is higher than that of a double-silver-layer low-radiation film with the same visible light transmission value, the radiation rate on the surface of the film layer is low, the shading coefficient is much lower, and the reflection rate is low; and the film has high hardness and high oxidation resistance, and different cold processing and hot treatment can be carried out after the film coating.

Description

technical field [0001] The invention relates to a temperable triple-silver low-radiation coated glass coated with a composite dielectric layer, an antireflection layer and a protective layer with high transmission and high efficiency sunshade performance. Background technique [0002] With the continuous pursuit of high transparency of external light and high shading performance of glass curtain walls, the contradiction between the two has become more prominent. There are low-emissivity coated glass coated with double silver layers on the market. Products with high visible light transmission generally have a high shading coefficient. There is no low-emissivity coated glass with a double-layer silver structure that satisfies both high transmittance and low shading coefficient. You can't have it both ways, you have to give it up. [0003] In the processing of double-silver layer and triple-silver layer low-e glass with traditional structure, the glass can only be processed by...

Problems solved by technology

[0007] The infiltration of sodium ions, the condensation of silver particles and the oxidation of the silver layer will cause spots and fogging of the coated glass, which will reduce the low-radiation performance
