Compared with the existing technology, it has low emissivity, sunshade, beautiful appearance, pure color, etc. Significant advantages.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a golden low-radiation coated glass with simple film structure, easy mass production, good coloring and remarkable energy-saving effect and a manufacturing method thereof. Background technique [0002] Low-radiation energy-saving coated glass is a kind of energy-saving coated glass that has been widely used. It improves the reflectivity of mid- and far-infrared radiation, obtains a small glass conductivity, and reduces the radiation and heat dissipation of indoor heating to the outside in winter, thereby reducing heating energy. consumption purpose.

[0003] Traditional low-emissivity energy-saving coated glass mainly includes transparent conductive oxide material SnO 2 : On-line coated glass of F and off-line coated glass based on metal Ag. At present, the appearance of low-e coating products based on these two types of materials in the market is mainly colorless and transparent. In order to obtain the function of color beautification, body dyeing can be used in the processing process Colored glass substrates, or multi-layer processing on the substrates for film system matching, the former needs to change the glass substrate repeatedly according to the final color of the product, the processing procedure is complicated, and the latter cannot obtain pure golden color due to the limitation of the coating material itself Appearance (mostly khaki or unable to obtain a golden color within the visible range of the human eye), especially on glass whose emissivity is ≤0.03 and whose thin film system is mainly composed of Ag and SnO2:F materials, it is difficult to achieve

[0004] Chinese patents ZL2008100656547 and ZL2012104512688 respectively disclose a golden low-emissivity coated glass and its manufacturing method. The former uses a composite metal film layer to achieve the golden appearance of the glass surface. During the manufacturing process, multiple coating operations are required on the glass substrate, while Since the appearance color of the product mainly comes from the copper plating layer in the composite metal film layer, the appearance color is not pure gold. In addition, the reflectance of the visible light film surface of the product is less than 55%, which can simplify the manufacturing process, improve the purity of the appearance color and There are deficiencies in the energy-saving effect; the latter uses Ag thin film as the functional layer, but there are still deficiencies in the appearance of color and the reflectivity of the visible light film surface.
