Abstract

The invention belongs to the field of solar energy technology, and discloses a low-emissivity coated glass, and a preparation method thereof. The low-emissivity coated glass comprises a glass substrate and a film stack arranged on at least one surface of the glass substrate; the film stack comprises n groups of laminated film layers, and a Si3N4 film on the outermost film layer of the n groups oflaminated film layers; each group of the laminated film layers comprises a SiO2 layer, a SiONx layer, a Si3N4 layer, a SiONx layer, a SiO2 layer, and a SiONx layer successively from the side close tothe glass substrate and the side far away from the glass substrate. The low-emissivity coated glass possesses low emissivity on certain light wave bands, relatively high visible light transmissivity,and relatively excellent film layer stability, and is suitable to be used in building doors and windows, curtain walls, and photovoltaic assemblies.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and in particular relates to a low-radiation coated glass and a preparation method thereof. Background technique [0002] Low-E glass, also known as Low-E glass, uses coating technology to coat the glass surface with a film system composed of multiple layers of metal or other compounds, so as to solve the contradiction between glass heat insulation performance and lighting performance. Low-E glass can have good heat insulation performance and lighting performance at the same time, and solve the problem of "light pollution". [0003] The current technologies for producing Low-E glass are mainly silver plating and interference film plating. Among them, the silver plating method is to sequentially plate a first metal / non-metal oxide protective layer, a nano-scale silver layer and a second metal / non-metal oxide protective layer on the glass surface, and utilize silver's high reflection effect o...
