Abstract

The invention discloses low-emissivity coated glass. According to the low-emissivity coated white glass, a first bottoming dielectric layer, a second barrier layer, a third dielectric layer, a fourth functional layer Ag (silver) layer, a fifth protecting layer and a sixth protecting layer are sequentially plated on a high-quality float glass substrate; the first bottoming dielectric layer can be made of SiNx (silicon nitride), ZnO (zinc oxide), ZnSnO (zinc stannum oxide) or TiOx (titanium oxide); the second barrier layer can be a NiCr (nickel-chromium) or Cr (chromium) layer; the third dielectric layer can be made of SiNx, ZnO, ZnSnO or TiOx; the fourth functional layer is an Ag layer; the fifth protecting layer can be a NiCr or Cr layer; and the sixth protecting layer can be a ZnO, ZnSnO, AZO (aluminum zinc oxide), SiNx or TiOx layer. The LOW-E (low-emissivity) coated white glass disclosed by the invention imitates the appearance effect of the green LOW-E coated glass, the rejection rate in a coating process is reduced, the production cost of the LOW-E glass is reduced, and the transmission color is closer to neutral.

Description

technical field [0001] The invention relates to a low-radiation energy-saving glass, in particular to a green low-radiation energy-saving glass. Background technique [0002] Low-E glass, also known as low-emissivity glass, Low-E coated glass is to use different materials to deposit a new material surface on the surface of the glass substrate to change the optical, electrical, mechanical and chemical properties of the glass to achieve decoration. , energy saving, environmental protection and other purposes of glass deep processing products. Compared with ordinary glass and heat-reflective coated glass, Low-E film has the following obvious advantages: it has high reflectivity to far-infrared radiation and maintains good light transmission performance, which can reduce indoor heat loss and maintain indoor temperature, thereby playing a role The role of energy saving. [0003] Green glass coated with Low-E film (green glass, commonly used F green glass) has good appearance de...
