Problems solved by technology

That is to say, it is not possible to use large plates of glass for coating and tempering. The low-emissivity coated glass currently produced does not have a high-hardness outermost protective layer, which is easily damaged during transportation, which reduces production efficiency and off-site processability.
Moreover, the emissivity of the glass surface of the produced low-e coated glass is still high, and it is impossible to achieve a good heat insulation effect
[0009]2. Appearance is not pure in color tone (appears earthy yellow tone)
[0010]3. Poor antioxidant performance and short effective storage time
Increased the difficulty of quality control in the production process

Abstract

The invention provides a piece of low-emissivity coated glass which comprises a glass substrate, wherein a first composite dielectric layer, a first protecting layer, an infrared baffle layer, a second protecting layer and a second composite dielectric layer are arranged outwards from the glass substrate in sequence; the first composite dielectric layer is made of SiOxNy; the infrared baffle layer is made of Ag; the first protecting layer and the second protecting layer are made of an NiCr alloy; and the second composite dielectric layer is made of ZnSnO3. According to the coated glass provided by the invention, by adjusting the thickness of each film layer, the reflection color of the coated glass is of 24K golden color, the penetration color is of distant blue, and moreover the reflection rate of the glass to far infrared rays is greatly improved because of the characteristics of silver, that is, the property of low-emissivity is achieved, and therefore the low-emissivity coated glass is applicable to practical use.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a low-radiation coated glass. Background technique [0002] In the prior art, the coating ratio, especially the low-emissivity coated glass, not only has the function of lighting, shading and energy saving, but also is very important for the beautification and decoration of buildings. Modern commercial buildings and residential buildings have higher and higher decorative requirements for glass, and various functions and colors are the goals pursued by architects. Coated glass manufacturers design different colors of coated glass to suit different color requirements. Low-emissivity coated glass is a functional material that prohibits the transmission of most infrared frequencies and allows visible light to pass through. Due to its high visible light transmittance and excellent heat insulation performance, low-e coated glass is widely used in the construction of curta...
