Abstract

The invention belongs to the technical field of glass, and particularly relates to tri-silver low-emissivity coated glass capable of being tempered and a preparation method thereof. According to the structure of the glass, a glass substrate, a first composite medium layer, a first silver layer, a first protection layer, a second composite medium layer, a second silver layer, a second protection layer, a third composite medium layer, a third silver layer, a third protection layer, a fourth composite medium layer and a zirconium oxide film are arranged in sequence. The film can bear high-temperature tempering at the temperature of 700 DEG C, the color is stable after tempering, and the film is free of appearance defects after being tempered.

Description

technical field [0001] The invention belongs to the technical field of glass, and in particular relates to a temperable triple-silver low-radiation coated glass and a preparation method thereof. Background technique [0002] Low-E coated glass is proven to be the best building energy-saving glass available today. By coating the surface of ordinary glass with a low-emissivity film to improve its performance, effectively limit the transmission of infrared light, and fully reduce the heat exchange on both sides of the glass, so that it has excellent energy-saving performance and optical performance compared with ordinary glass and traditional coated glass. and environmental performance. Low-emissivity coated glass has been widely used in buildings all over the world, especially in countries and regions with relatively developed economy, science and technology. The low-e coating itself is also being updated with the deepening of research and development, which not only meets t...
