Problems solved by technology

However, in fact, the thick antimony-doped tin oxide layer not only increases the haze of the layer itself, but also increases the surface roughness of the fluorine-doped tin oxide layer grown on it, which increases the overall haze of the coated glass.

Embodiment Construction

[0013] Now illustrate the present invention with 1-8 embodiment;

[0014] In this example, chemical vapor deposition is used to deposit each film layer. The specific steps are:

[0015] In the first step, a carbon-doped silicon oxide layer is plated as a color suppression layer. Specifically, silane, ethylene, carbon dioxide, and carrier gas nitrogen are formed into a mixed gas according to the volume ratio [1~10%]:[10~40%]:[10~40%]:[10~79%], and the mixed gas It is introduced into the feed chamber of the coater, and sprayed onto the moving hot glass surface below it through the feed slit under the coater, and flows through the glass surface in a laminar flow, and a chemical reaction occurs on the glass surface. deposited into a film. The temperature of the hot glass is 660-700°C, the speed of the glass is 100-500 m / hour, and the refractive index of the film is 1.6-1.8 and the thickness is 50-100nm.

[0016] In the second step, an antimony-doped tin oxide layer is deposited...

Abstract

The invention relates to a reflective solar-control low-emissivity coated glass and a preparation method thereof, belonging to the technical field of glass coating. In order to overcome the defects in the existing coated glass, the glass film combination design is improved: a carbon-doped silicon oxide layer, a stibium-doped tin oxide layer, a fluorine-doped tin oxide layer and a phosphorus-doped titanium oxide layer are sequentially coated on a common float glass substrate. By the effective combination and matching of the film layers, the coated glass has the following advantages: the integral haze of the coated glass is small and controllable; the visible light reflectivity is within the acceptable range, and can not result in light reflection pollution; and the properties (the solar thermal coefficient is smaller than or equal to 0.5, the visible light transmittance is greater than or equal to 45%, and the emissivity is smaller than or equal to 0.20) are perfectly combined.

Description

technical field [0001] The invention relates to a reflective solar control low-emissivity coated glass and a preparation method thereof, which belongs to the technical field of glass coating and is a low-haze coated glass with proper reflection and transmission of visible light, certain low-radiation characteristics and sunlight control function , especially suitable for building window glass. Background technique [0002] In modern buildings, coated glass is used on the outer wall. With the continuous improvement of building energy-saving requirements, the coated glass used is required to achieve a certain sunlight control function, a certain visible light transmittance, better heat insulation performance, and Visually decorative beauty. Among them, the sunlight control function refers to the amount of regulation that limits sunlight heat energy from entering the room through the glass, expressed by the solar heat gain coefficient (SHGC). If the coating layer can provide ...
