Abstract

The invention relates to the technical field of coated glass, in particular to temperable high-transparency and low-radiation coated glass and a manufacturing method of the glass. The glass comprises a glass substrate and a coating layer deposited on the surface of the glass substrate, wherein the coating layer comprises a first medium layer, a first growth layer, a first protection layer, a silver layer, a second protection layer, a second growth layer and a second medium layer. The coated glass comprises the growth layers, the silver layer and the protection layer; Ar and H2 mixed sputtering gas are used to substitute the original Ar and O2 mixed sputtering gas; O introduction is reduced in a sputtering process; oxidization of the protection layers and the silver layer is avoided; a binding force of a film layer is greatly improved; the further processing of the low-radiation coated glass is facilitated; in addition, H is doped to form a stable AZO:H (or GZO:H and IZO:H) transparent conductive oxide to further reduce the resistivity of the low-radiation film layer; the infrared reflection is enhanced; and the light-heat performance is further improved.

Description

technical field [0001] The invention relates to the technical field of coated glass, in particular to a toughened high-transmittance and low-radiation coated glass and a manufacturing method thereof. Background technique [0002] LOW-E coated glass, also known as low-emissivity coated glass, is an energy-saving building product formed by coating one or more layers of nano-functional films with infrared reflection properties on the surface of ordinary float glass. The coated glass product has a high visible light transmittance, has the characteristics of strongly blocking infrared rays, and can play the dual functions of natural lighting and heat insulation and energy saving. It can effectively reduce the loss of indoor heat in winter, and can block the secondary radiation of outdoor objects heated by sunlight in summer, thereby playing the role of saving energy and reducing consumption. [0003] High-transmittance single-silver LOW-E coated glass has high visible light tran...
