High-definition, neutral-color and low-emissivity coated glass and preparation method

Abstract

The invention provides high-definition, neutral-color and low-emissivity coated glass and a preparation method, belongs to the technical field of glass production, and aims at solving the technical problem that existing low-emissivity glass is poor in clarity and transparency. According to the invention, the low-emissivity glass is characterized by comprising a glass substrate layer and a coating layer located at one side of the glass substrate layer, wherein the coating layer is sequentially compounded with 10 films outwards from the glass substrate layer, wherein the first layer is a ZnSnO / ZnO layer or a mixed layer of ZnSnO and ZnO; the second layer is a Ag layer, the third layer is a Cu layer, the fourth layer is a NiCr layer, the fifth layer is a F2O3 layer, the sixth layer is a ZnSnO / ZnO layer or a mixed layer of ZnSnO and ZnO, the seventh layer is a Ag layer, the eighth layer is a NiCr layer, the ninth layer is a F2O3 layer and the tenth layer is a SiNx layer. The high-definition, neutral-color and low-emissivity coated glass has the advantage of good clarity and transparency.

Description

technical field [0001] The invention belongs to the technical field of glass production, and relates to a high-definition neutral color low-radiation coated glass and a preparation method. Background technique [0002] 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 according to the number of functional layers of silver, Low-E glass can be divided into single silver Low-E glass, double silver Low-E glass, and triple silver Low-E glass. At present, single-silver and double-silver are relatively mature energy-saving solutions in the field of architectural glass. The energy-saving effect of triple-silver energy-saving glass is better than that of double-silver and single-silver. However, the structure of the triple-silver glass film layer is complicated, and the process control is difficult, so the cost is hi...

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 small-angle discoloration, and the film surface has a heavy tone, which affects the decorative effect

[0007] 3) The overall production cost of double-silver products is still high, and the civilian market promotion lacks motivation
