A kind of orange-red double-silver low-emissivity coated glass and its preparation method

Abstract

The invention provides orange red double-silver low-emissivity coated glass and a preparation method thereof, belongs to the technical field of magnetron sputtering coating and solves the technical problems of high reflectivity, low definition and the like of existing coated glass. The orange red double-silver low-emissivity coated glass comprises a glass substrate layer and a coated layer, eleven film layers are sequentially compounded on the coated layer outwards from the glass substrate layer, the first layer is an SiNx layer, the second layer is a ZnO layer, the third layer is an Ag layer, the fourth layer is a Cu layer, the fifth layer is an NiCr layer, the sixth layer is an AZO layer, the seventh layer is an SiNx layer, the eighth layer is a ZnSnO / ZnO or ZnSnO and ZnO mixed layer, the ninth layer is an Ag layer, the tenth layer is an NiCr layer, the eleventh layer is an SiNx layer, and the film layers of the coated layer are sputtered layer by layer by magnetron sputtering. The orange red double-silver low-emissivity coated glass has the advantages of low reflectivity, high definition and the like.

Description

technical field [0001] The invention belongs to the technical field of magnetron sputtering coating, and relates to an orange-red double-silver low-radiation coating glass and a preparation method thereof. Background technique [0002] Coated glass (Reflect ive glass) is also called reflective glass. Coated glass is coated with one or more layers of metal, alloy or metal compound films on the surface of the glass to change the optical properties of the glass to meet certain requirements. Among them, Low-e energy-saving coated glass can effectively block ultraviolet rays and infrared rays, has high transmittance to visible light, low emissivity, and can effectively reduce heat transfer. It is currently the most widely used energy-saving building material. The Low-E glass production process in the prior art is to plate a multilayer film system with Ag as the functional layer, including a dielectric layer and other metal layers on a high-quality float substrate. If divided ac...

AI Technical Summary

Problems solved by technology

[0005] 1) Although there are currently double silver neutral color products, they are still not clear enough in general, and there is a problem of yellowing / greening through the color

[0006] 2) Most of the current double-silver products have discoloration at small angles, and the color controllability of batches is poor, and there are color differences visible to the naked eye when viewed closely

[0007] 3) Medium and low-permeability films have high reflectivity, poor visual effects, and the overall sense of turbidity is not pure enough, etc.
