Problems solved by technology

[0002] The traditional double-silver low-emissivity coated glass is made by vacuum magnetron sputtering coating technology. The protective layer, the second dielectric layer, the second silver layer, the second protective layer and the third dielectric layer. The double-silver low-emissivity coated glass with this structure has a big disadvantage in terms of color. This kind of glass is viewed from the side at a small angle. Compared with the front view of the glass, there is redness and purple phenomenon, which affects the overall appearance of the glass curtain wall after glass assembly, and the color of the film surface of this kind of glass is red, not soft enough, and there are double images when observed, and The translucent color of the coated glass is greenish, not neutral enough, so that the glass curtain wall cannot achieve a soft and neutral color and a comfortable appearance effect

Abstract

The invention relates to the technical field of coated glasses, in particular to a piece of double-silver low-emissivity coated glass and a preparation method thereof. The coated glass adopts magnetron sputtering coating and comprises a glass substrate, and a film layer coated on the surface of the glass substrate, wherein the film layer comprises a first dielectric layer, a first silver layer, a first protective layer, a second dielectric layer, a second silver layer, a second protective layer, a third dielectric layer, a third protective layer and a fourth dielectric layer from one side of the glass substrate outwards in sequence. Compared with the prior art, the third protective layer and the fourth dielectric layer are additionally arranged, and the problem that the side surface of the coated glass changes in color when being observed from small angle is solved. Moreover, the film surface color and the penetration color are neutral, the whole color is soft and beautiful, and as a result, a comfortable feeling is offered for people.
