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

Abstract

The invention provides blue-gray three-silver low-emissivity coated glass and a preparation method thereof, and belongs to the technical field of magnetron sputtering coating. The blue-gray three-silver low-emissivity coated glass comprises a glass substrate layer and coating layers, the coating layers comprise seventeen coating layers sequentially compounded from the glass substrate layer to the outside, the first layer and the second layer adopt a first dielectric combination layer, the third layer adopts a low-emissivity functional layer, the fourth layer adopts a first blocking protective layer, the fifth layer adopts a crystal bed dielectric layer, the sixth layer and the seventh layer adopt a second dielectric combined layer, the eighth layer adopts a low-emissivity functional layer, the ninth layer adopts a low-emissivity functional layer, the tenth layer and the eleventh layer adopt a second blocking protective layer, the twelfth layer adopts a crystal bed dielectric layer, the thirteenth layer and the fourteenth layer adopt a third dielectric combined layer, the fifteenth layer adopts a low-emissivity functional layer, the sixteenth layer adopts a third blocking protective layer, and the seventeenth layer adopts a fourth dielectric layer. The glass is blue gray, and the problem that conventional three-silver blue coated glass is turbid in color and insufficient in permeability is solved.

Description

technical field [0001] The invention belongs to the technical field of magnetron sputtering coating, and in particular relates to a blue-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 process...

Problems solved by technology

[0005] 1) Although there are blue 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
