Abstract

The invention relates to the technical field of glass manufacturing, in particular to middle-transparent temperable three-silver low-emissivity coated glass which comprises a glass substrate and a coating layer, the coating layer is sequentially compounded with fifteen film layers from the glass substrate to the outside, namely a first SiNx layer, a second ZnOx layer, a third Ag layer, a fourth AZO layer, a fifth ZnSnOx layer, a sixth ZnOx layer, a seventh Ag layer and an eighth NiCr layer, and the first SiNx layer, the second ZnOx layer, the third Ag layer, the fourth AZO layer, the fifth ZnSnOx layer, the sixth ZnOx layer, the seventh Ag layer and the eighth NiCr layer are sequentially compounded from the glass substrate to the outside. The first layer is a NiCr layer, the ninth layer is an AZO layer, the tenth layer is a ZnSnOx layer, the eleventh layer is a ZnOx layer, the twelfth layer is an Ag layer, the thirteenth layer is a NiCr layer, the fourteenth layer is an AZO layer, and the fifteenth layer is a SiNx layer. By designing the film layer structure, the problem that the transmission color of the film layer is yellowish and greenish is solved, the transmission color is neutral, the transmittance is moderate, the color difference of the front and side surfaces of the coated glass is small, and the performance is excellent.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a medium-transparent temperable triple-silver low-radiation coated glass. Background technique [0002] Glass is the third largest building material after reinforced concrete. It has good permeability, wind and snow protection, and is widely used in buildings. With the development of modern technology, glass has been endowed with various new connotations. Among them, low-E glass has been widely used in the field of building curtain wall due to its beautiful color, good texture and excellent energy-saving characteristics. Low-E glass is a glass substrate, through magnetron sputtering method, using different film materials to match each other, deposit a nano film layer, and then change the optical, electrical, mechanical and chemical properties of the glass, to achieve decorative, Energy saving, environmental protection and other purposes. According to the specific sc...
