Problems solved by technology

However, because the silver film is soft and easy to scratch, it is easy to be oxidized or corroded when exposed to the air, and its optical and electrical properties will be greatly reduced under the action of thermal oxidation and corrosion caused by chlorine and sulfur.
More seriously, it even loses the low-emissivity performance; and the existing low-emissivity glass will have a little different colors appear on the reflective surface of the glass when viewed from a certain angle, which will cause chromatic aberration to a certain extent and affect the appearance; the color of the glass will also Simple and single, can not meet people's needs for color

Abstract

The invention provides tempering low-emissivity coated glass containing silver alloy. The glass comprises a glass substrate and a coating layer deposited on the glass substrate, and is characterized in that the coating layer comprises two or more functional layers, at least one of the functional layers is a silver alloy layer, and the silver alloy layer is made from one of Ag-Cu-Ni or Ag-Cu-Al or Ag-Cu-Pt. According to the tempering low-emissivity coated glass containing the silver alloy provided by the invention, a traditional Ag layer is substituted by the silver alloy layer, a small quantity of alloy metal elements are doped in the Ag layer, Ag crystal particles are refined, the hardness, the abrasive resistance and the burning loss resistance of silver are improved, the optical performance of Ag is changed, the overall glass is perspective and grey, the outdoor color is neutral and is close to natural color which is real and beautiful, and thus the demand of people on the color is satisfied; meanwhile, the processability of the glass is improved, and the oxidation resistance of the glass is enhanced.

Description

technical field [0001] The invention relates to the technical field of low-emissivity coated glass, in particular to a temperable low-emissivity coated glass containing silver alloy. Background technique [0002] Low-E glass is also called Low-E glass. Low-E glass uses vacuum magnetron sputtering to coat the glass surface with a film system containing one, two or three layers of silver to reduce energy absorption or control indoor and outdoor energy exchange, so as to ensure the comfort of life and work. Sex, and in order to achieve the purpose of environmental protection and energy saving. [0003] Low-E glass has the characteristics of low heat transfer coefficient and infrared reflection. Its main function is to reduce the radiant energy transfer of indoor and outdoor far-infrared rays, and allow solar radiation to enter the room as much as possible, thereby maintaining the indoor temperature and saving heating and air conditioning costs. Low-emissivity glass is a new ...
