Abstract

The invention provides an off-line light gray single-silver coated glass with low light transmittance and a preparation method thereof. The coated glass includes a glass substrate and a ferromanganese nitride layer, a silicon alloy film layer, a first A dielectric layer, a first barrier layer, an Ag layer, a second barrier layer and a second dielectric layer. The invention forms a ferromanganese nitride layer and a silicon alloy thin film layer by magnetron sputtering on a glass substrate, and utilizes the blocking and synergistic effects of the two to improve the heat insulation and photothermal properties of the glass.

Description

technical field [0001] The invention belongs to the field of glass manufacturing, and relates to off-line light gray single-silver coated glass and a preparation method thereof, in particular to off-line light gray single-silver coated glass with energy saving and low transmittance and a preparation method thereof. Background technique [0002] Low-emissivity coated glass refers to the film-based glass coated with multiple layers of metal or other compounds on the glass surface, also known as low-emissivity glass or "Low-E" glass. Due to the existence of this layer of film, compared with ordinary glass, the surface emissivity of coated glass is lower and has spectral selectivity. The low-emissivity layer film has a high reflective ability to far-infrared rays with a wavelength of 2.5 μm to 40 μm. This good barrier to heat radiation penetration allows it to reflect most of the indoor heat radiation back to the room in winter, ensuring indoor The heat is not dissipated outwar...
