Abstract

The invention discloses a temperable low-radiation coated glass which is characterized in that a dielectric layer I (2), a dielectric layer II (3), a metal barrier layer I (4), a silver layer (5), a metal barrier layer II (6), a dielectric layer III (7) and a dielectric layer IV (8) are arranged on the surface of a glass substrate (1) from bottom to top in turn; the dielectric layer I (2) is connected with the surface of the glass substrate (1); and the dielectric layer I (2) and the dielectric layer IV (8) are silica layers, the dielectric layer II (3) and the dielectric layer III (7) are stagnate layers of zinc oxide, and the metal barrier layer I (4) and the metal barrier layer II (6) are nichrome alloy layers. Simultaneously, the invention also discloses a method for preparing the temperable low-radiation coated glass. The temperable low-radiation coated glass has the characteristics of good thermal stability, good oxidation resistance, good membrane layer firmness, good wear resistance and alkali resistance and the like.

Description

technical field [0001] The invention relates to the field of glass, in particular to a temperable low-radiation coated glass and a preparation method thereof. Background technique [0002] Chinese patent CN2721633 discloses a low-emissivity coated glass with a special film system, including a glass substrate, and five film layers are compounded on the glass substrate. The first film layer, the bottom layer, is a metal oxide film layer; the second film layer It is a metal or alloy barrier layer; the third film layer is metal silver; the fourth film layer is a metal or alloy barrier layer; the fifth film layer, that is, the surface layer, is a metal oxide film layer. This structure can ensure that the silver layer is not affected by oxygen and prevent the silver layer from being oxidized, so that the silver layer, one of the functional film layers of the low-emissivity coated glass, can play a good role, thereby obtaining a stable low-emissivity function. The low-radiation co...
