Abstract

The invention relates to a golden low radiation film coating glass, and the single surface of the glass is coated with a composite film, and the outermost layer of the composite film is provided with a protective film, and the composite film comprises three metal films, wherein, one metal film is a copper film, one is a silver film and one metal layer which clings to the protective film is a nichrome film or a titanium film. The making method comprises washing, drying and coating, and the coating is vacuum magnetron coating, and the dried glass which is put into a target material chamber of the vacuum magnetron equipment is coated with composite films layer by layer. The golden low radiation film coating glass of the invention chooses specific target material, atmosphere and combination to replace gold target materials to make the golden color low radiation film coating glasses, and the golden low radiation film coating glass is characterized by excellent performance, brilliant color, easy regulation, stable quality, high making efficiency, low cost and easy popularization, which can obtain various golden low radiation film coating glasses with different transmittances, transmission colors, reflectivities, reflective colors, sunshade coefficiencies and emissivities by changing the thicknesses of each film, thus being adaptable to different needs of the market.

Description

technical field [0001] The invention relates to coated glass, in particular to a golden low-radiation coated glass and a manufacturing method thereof. Background technique [0002] Low-emissivity coated glass, also known as low-emissivity glass or "Low-E" glass, is coated with one or more layers of special metal or metal oxide and metal nitride films on a single surface of a glass substrate, thereby forming various visual effects and With different optical and thermal performance characteristics. It has a high reflectance for infrared rays with a wavelength range of 0.78 μm to 2.50 μm, and has good heat insulation performance. This product integrates multiple functions such as decorating the appearance of buildings, controlling light, adjusting heat, saving energy, and improving the environment. It is widely used in various industries such as construction, transportation, and entertainment. However, the existing golden low-emissivity coated glass adopts pure gold target ma...
