Problems solved by technology

However, only when the AZO film is thicker can it have a certain low-radiation performance. In actual production, more target positions are required and the cost is higher.
At the same time, after a period of installation and use of the ceramic AZO target, the surface is prone to nodulation discharge, which seriously affects the power and life of the target, and also causes the hidden danger of color fluctuation of the coated product.

Abstract

The invention provides a novel low-emissivity coated glass which comprises a glass substrate and a coating layer, wherein the coating layer sequentially comprises a first layer SiO2, a second layer LaB6-AZO and a third layer SiO2 from inside to outside; and the thickness of the second layer LaB6-AZO is 400-500nm. The invention also provides a preparation method of the coated glass. The coated glass has the advantages of higher visible light transmittance (3-4% higher than AZO); in the low-emissivity product, the coated glass can substitute the silver layer, can not be easily oxidized, and can be used as a uniwafer; the product has the advantages of low emissivity, stable performance and stable optical and thermal properties; and the method is suitable for large-scale production. The glass has the characteristics of favorable appearance color, low tendency to shedding and oxidation of the coating and the like, and can be used in a uniwafer, interlayer or hollow mode.

Description

technical field [0001] The invention relates to a coated glass, more specifically to a low-radiation coated glass and a preparation method thereof. Background technique [0002] At present, most low-radiation products need to be coated with an infrared reflective layer of Ag to achieve the low-radiation effect, and products containing Ag film are very easy to be oxidized, and it is difficult to be directly exposed to outdoor use. It needs to be used in a hollow, which increases the cost. The online Low-E radiation rate is relatively high, and online coating equipment is required to complete production, and the initial investment cost is relatively high. [0003] Transparent conductive film has a certain low-radiation performance, but because the ITO film contains the rare metal indium (In), it is expensive. AZO is widely used as a transparent conductive film instead of ITO film in large-area coated glass. Ceramic zinc-aluminum oxide (AZO) has been widely researched and appl...
