Abstract

The invention relates to a triple-silver low-emissivity coated glass, which comprises a glass body and a coating film coated on the glass body. The coating film comprises two dielectric combination layers, three silver layers and two spacing layer dielectric combination layers. The two dielectric combination layers are respectively arranged at the upper layer and the lower layer of a coating layer. The three silver layers and the two spacing layer dielectric combination layers are alternately arranged between the two dielectric combination layers in order. The dielectric combination layers and the spacing layer dielectric combination layers are all composed of one or more film layers of SSTOx, CrNx, CdO, MnO2, InSbOx, TxO, SnO2, ZnO, ZnSnOx, ZnSnPbOx, ZrO2, AZO, Si3N4, SiO2, SiOxNy, BiO2, Al2O3, Nb2O5, Ta2O5, In2O3 and MoO3. The triple-silver low-emissivity coated glass disclosed in the invention abolishes a metal barrier layer in a traditional film layer structure, and employs novel material dielectric combination layers to conduct silver layer protection, so that the influence of film layers on visible light transmittance can be effectively reduced, and consequently, high visible light transmittance, low emissivity, and a good photothermal ratio can be obtained. Besides, with diverse color options, the triple-silver low-emissivity coated glass has a wide range of application.

Description

technical field [0001] The invention relates to a glass, in particular to a triple-silver low-radiation coated glass and a preparation method thereof. Background technique [0002] Low-emissivity coated glass (also known as LOW-E glass) is a film system product composed of multiple layers of metal or other compounds coated on the glass surface. Low-emissivity coated glass is a kind of glass that not only allows outdoor solar energy and visible light to pass through like ordinary glass, but also acts like an infrared reflector (especially with high reflectivity for mid- and far-infrared rays) to reflect the secondary radiant heat of objects back A new generation of coated glass. Used in any climatic environment, it can achieve the functions of controlling sunlight, saving energy, controlling heat and improving the environment. [0003] Triple-silver low-emissivity glass (Triple-silver LOW-E), as a high-end product in low-emissivity coated glass, consists of up to three laye...
