Problems solved by technology

At present, most of the traditional low-emissivity energy-saving glass uses metallic silver as the film material of the low-emissivity layer, and other film layers mainly play the role of protecting and isolating the silver film layer. , is easily oxidized and loses the low-radiation energy-saving effect. Therefore, this type of energy-saving glass has poor weather resistance and corrosion resistance when used, and the service life of glass products is easily affected by it. The energy-saving effect in actual use will gradually decrease. reduce
At the same time, because silver is easily oxidized, it is not suitable for off-site processing, and special attention needs to be paid during transportation, resulting in increased costs

Abstract

The invention discloses a low-radiation energy-saving glass with a silver-titanium composite functional layer and a preparation method thereof. A functional layer, a second indium tin oxide film layer, and a protective layer. The silver-titanium composite functional layer uses metal silver layer and metal titanium layer to achieve low emissivity, high visible light transmittance, and high infrared reflectivity. The silver layer mainly achieves low resistance and improves infrared reflectivity. The metal titanium layer can further reduce surface resistance. While protecting the silver layer from pollution; compared with the traditional silver-based low-emissivity energy-saving glass, the present invention has the advantages of strong weather resistance, adjustable color, low emissivity, etc., and the process flow is simple.

Description

technical field [0001] The invention relates to a coated energy-saving glass and a preparation method thereof, in particular to a silver-titanium composite functional layer low-radiation energy-saving glass and a preparation method thereof. Background technique [0002] Low-radiation energy-saving glass plays an important role in the energy-saving aspects of buildings and automobiles, and has become an important development direction for energy-saving and emission-reduction development. Low-radiation energy-saving glass is a filter material developed in recent years. It uniformly coats a film system on the surface of float flat glass by online or offline coating methods, which can effectively improve the infrared reflectivity of the glass surface and reduce ultraviolet rays, etc. At the same time, visible light can pass through effectively without affecting indoor lighting. Through the above controllable and selective filtering of light, infrared and ultraviolet rays can be...
