Problems solved by technology

The process of producing coated glass by sol-gel method is simple and has good stability. The disadvantage is that the light transmittance of the product is too high and the decoration is poor.
[0007] At present, there are not many researches on the production of sun-shading double-silver low-e coated glass, which solves the high transmission and low sun-shading requirements that cannot be solved by single silver low-e coated glass

Abstract

The invention discloses a sunshade type double-silver low-emissivity coated glass and a preparation method thereof. The sunshade type double-silver low-emission coated glass comprises a glass substrate, a first silicon-aluminum alloy film, and a second zinc-aluminum alloy film which are sequentially and tightly laminated. alloy film; the third silver film; the fourth nickel-cadmium alloy film; the fifth silicon-aluminum alloy film; the sixth zinc-aluminum alloy film; the seventh silver film; the eighth nickel-cadmium alloy film; The preparation method comprises steps: 1) sintering target material; 2) pretreatment of glass; 3) coating treatment. The present invention is a double-silver low-emissivity coated glass made by light interference of various metal materials on an ordinary colorless and transparent float glass substrate. The reflected color is light gray under sunlight, which can achieve good decoration and energy-saving effects; The product can be processed in different places to reduce the manufacturing cost of processing enterprises; it can also be made into insulating glass to achieve better light control and energy saving effects.

Description

technical field [0001] The invention relates to a method for preparing coated glass and the coated glass prepared by the method, in particular to a method for preparing sun-shading double-silver low-emissivity coated glass and the prepared sun-shading double-silver low-emissivity coated glass. Background technique [0002] Reflective glass is also called reflective glass. Coated glass is coated with one or more layers of metal, alloy or metal compound films on the surface of the glass to change the optical properties of the glass to meet certain requirements. Coated glass can be divided into the following categories according to the different characteristics of the product: heat reflective glass, low-emissivity glass (Low-E), conductive film glass, etc. [0003] There are many production methods for coated glass, such as vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition, and sol-gel methods. Magnetron sputtering coating glass can design and manufac...
