Energy-saving coated glass and application thereof

Abstract

The invention belongs to the technical field of coated glass, and in particular relates to energy-saving coated glass, which comprises a glass substrate and an SnO2: Sb layer arranged on the surface of the glass substrate, wherein the mass ratio of SnO2: Sb in the SnO2: Sb layer is 100: (2-5), and the thickness of the SnO2: Sb layer is 300-600 nm. The energy-saving coated glass has high transmittance and low reflectance in visible light band, the transmittance in visible light band is more than 70%, and the reflectance in visible light band is less than 20%, the lighting effect of the energy-saving coated glass is ensured, and optical pollution caused by glass reflection can be greatly reduced. In addition, the energy-saving coated glass has higher reflectivity in the infrared band where light energy is concentrated, and the reflectivity in the infrared band is more than 16%, so that the influence of light radiation energy on a room can be effectively adjusted, and the energy-saving coated glass is more energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of coated glass, and in particular relates to an energy-saving coated glass and its application. Background technique [0002] China's existing urban construction area exceeds 40 billion square meters. The trend of modern buildings is to use large areas of glass or even glass walls. Most of the energy-saving performance is not ideal. In energy-saving buildings, glass is one of the main entrances and exits of building energy consumption. At present, the heat-reflective coated glass widely used in the market is mostly silicon-based coated glass. However, the reflectance of silicon-based coated glass is very high, generally between 30% and 50%, and the transmittance is relatively low, generally less than 50%. Coated glass is widely used in construction. Therefore, the research on energy-saving coated glass has great application prospects and market demand. [0003] The energy-saving coated glass currently on...
