Problems solved by technology

However, low-emissivity glass is realized by coating the glass surface with a metal film layer. Traditionally, coated glass has several layers of metal layers, which have a certain degree of attenuation of visible light transmittance, which will affect indoor lighting.

Embodiment 1

[0046] A coated glass with ultra-high visible light transmittance, including a glass substrate 1, which is a 6mm float white glass, including:

[0047] The first silicon nitride film layer 2 has high compatibility and improves the bonding force between the film layer and the glass substrate 1;

[0048] The first niobium oxide film layer 3 has a very low extinction coefficient, which reduces the absorption of visible light by the film layer and improves the visible light transmittance;

[0049] The zinc oxide aluminum film layer 4 has a dense and smooth surface structure, providing a film-forming platform for the silver film layer 5;

[0050] The silver film layer 5 has very high reflection characteristics for ultraviolet light, near-infrared light and far-infrared light, and reduces the emissivity value of the coated glass;

[0051] The nickel-chromium oxide film layer 6 not only prevents the silver film layer from being oxidized and corroded, but also has a very low extincti...

Embodiment 2

[0074] The same part of this embodiment and Embodiment 1 will not be described again, the difference is:

[0075] The thickness of the first silicon nitride film layer 2 is 27nm, the thickness of the first niobium oxide film layer 3 is 13nm, the thickness of the zinc-aluminum oxide film layer 4 is 13nm, the thickness of the silver film layer 5 is 12nm, and the nickel-chromium oxide film layer The thickness of 6 is 2nm, the thickness of zinc tin antimony film layer 7 is 12nm, the thickness of the second niobium oxide film layer 8 is 12nm, the thickness of the second silicon nitride film layer 9 is 26nm, the thickness of titanium oxide film layer 10 2nm.

[0076] After the coating is completed, the visible light transmittance of the glass is 90%, the apparent emissivity of the film surface is 0.08, and there are no visible defects such as pinholes and scratches.

Embodiment 3

[0078] The same part of this embodiment and Embodiment 1 will not be described again, the difference is:

[0079] The thickness of the first silicon nitride film layer 2 is 33nm, the thickness of the first niobium oxide film layer 3 is 16nm, the thickness of the zinc-aluminum oxide film layer 4 is 17nm, the thickness of the silver film layer 5 is 16nm, and the nickel-chromium oxide film layer The thickness of 6 is 3nm, the thickness of zinc tin antimony film layer 7 is 17nm, the thickness of the second niobium oxide film layer 8 is 16nm, the thickness of the second silicon nitride film layer 9 is 33nm, the thickness of titanium oxide film layer 10 4nm.

[0080] After the coating is completed, the visible light transmittance of the glass is 90%, the apparent emissivity of the film surface is 0.07, and there are no visible defects such as pinholes and scratches.

Abstract

The invention discloses coated glass being ultrahigh in visible light transmittance and a preparation method thereof and belongs to the technical field of coated glass. The coated glass includes a glass substrate, and includes following layers outwardly from the glass substrate successively: a first silicon nitride film layer, a first niobium oxide film layer, a zinc aluminum oxide film layer, a silver film layer, a nickel chromium oxide film layer, a zinc tin antimony oxide film layer, a second niobium oxide film layer, a second silicon nitride film layer and a titanium oxide film layer. The coated glass is low in emissivity and is ultrahigh in the visible light transmittance.

Description

technical field [0001] The invention relates to the technical field of coated glass, in particular to a coated glass with ultra-high visible light transmittance and a preparation method thereof. Background technique [0002] The application of building energy-saving products has become the mainstream of the international construction industry. Many developed countries guide, encourage and regulate the construction and building materials market from product technology development, technical guidance, application promotion to legislation, etc. The application of energy-saving building material products has broad prospects. space. At present, our country advocates building energy conservation and environmental protection very much. The State Economic and Trade Commission clearly pointed out in the "Tenth Five-Year Plan" plan of the building materials industry that we should pay attention to the research, development and application of low-emissivity glass. However, low-emissiv...
