Light gray three-silver low-emissivity coated glass and preparation method thereof

Abstract

The invention provides light gray three-silver low-emissivity coated glass and a preparation method thereof, and belongs to the technical field of magnetron sputtering coating. According to the invention, through optimal design of a coating layer of the coated glass, the transmittance, wear resistance and oxidation resistance of the coated glass are improved; the light gray three-silver low-radiation coated glass comprises a glass substrate layer and the coating layer; the coating layer is sequentially compounded with eighteen film layers from the glass substrate layer to the outside, the first layer and the second layer are first dielectric medium combination layers, the third layer is a first low-radiation functional layer, the fourth layer is a first blocking protection layer, the fifth layer is a first crystal bed dielectric layer, the sixth layer and the seventh layer are second dielectric combination layers, the eighth layer is a second low-radiation functional layer, the ninth layer is a color adjustment layer, the tenth layer and the eleventh layer are second barrier protection layers, the twelfth layer is a second crystal bed dielectric layer, and the thirteenth layer and the fourteenth layer are third dielectric combination layers. The glass has the advantages of high transmittance, wear resistance, oxidation resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of magnetron sputtering coating, and in particular relates to a light gray three-silver low-radiation coating glass and a preparation method thereof. Background technique [0002] The Low-E glass production process of the prior art is to plate a multi-layer 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 functional layer and the number of silver layers, 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 proces...

Problems solved by technology

[0005] 1) Although there are gray three-silver products on the market, the color is not pure enough, the color of the film surface is heavy, and there are not many types to choose from

[0006] 2) Most of the current Sanyin products are blue-green in color, and the decorative effect is not good

[0007] 3) The structure of the three-silver Low-E glass film layer is complex, and the process debugging and processing production control are difficult
