Abstract

The invention provides a double-silver low-emissivity glass and a production process thereof. The double-silver low-emissivity glass comprises a glass substrate; a double-silver low-radiation film layer is arranged on the surface of the glass substrate, and consists of a first SnOx layer, a first ZnOx layer, a first AgTi layer, a second ZnOx layer, a second SnOx layer, a third ZnOx layer, a secondAgTi layer, a fourth ZnOx layer and a third SnOx layer that are sequentially arranged on one side of the glass substrate from the inside out; and the double-silver low-radiation film layer is platedon the surface of the glass substrate by magnetron sputtering process. According to the double-silver low-emissivity glass, the double-silver low-radiation film layer is plated on the surface of the glass substrate through magnetron sputtering process, and the obtained double-silver low-emissivity glass has the advantages of high visible light transmittance, high shading coefficient, good heat transfer performance, low production and manufacturing cost, and good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of glass production, and in particular relates to a double-silver low-emissivity glass and a production process thereof. Background technique [0002] Low-E glass, also known as low-emissivity glass, is a film system product composed of multiple layers of metal or other compounds coated on the glass surface. Its coating layer has the characteristics of high transmission of visible light and high reflection of mid- and far-infrared rays, which makes it have excellent heat insulation effect and good light transmission compared with ordinary glass and traditional architectural coated glass. [0003] Glass is an important building material. With the continuous improvement of decorative requirements for buildings, the use of glass in the construction industry is also increasing. However, when people choose glass doors and windows for buildings today, in addition to considering their aesthetic and appearance feat...
