preparation example Construction

[0027] In addition, an embodiment of the present invention also provides a method for preparing a switchable glass, for example, for preparing the aforementioned switchable glass 200 . Such as figure 2 As shown, the preparation method of dimming glass includes steps, for example:

[0028] S11: Provide a substrate.

[0029]S12: forming a first conductive layer on the substrate. Specifically, the substrate is heated to a preset temperature, the range of the preset temperature is, for example, 280-300°C, and one or a combination of at least two of FTO, ITO, IGZO, AZO, GZO, and Ag is used as the target material , and deposit the first conductive layer under the preset vacuum sputtering pressure. The preset vacuum sputtering pressure is, for example, 1.0E -3 ~9.0E - 3 mbar. Preferably, the first conductive layer may also be a pre-prepared conductive film layer. This can achieve better refractive index matching between film layers.

[0030] S13: forming a first auxiliary d...

specific Embodiment

[0047] A kind of dimming glass, its film layer structure from the substrate to the outside is: ITO (150nm) / NiVOx (80nm) / Li (40nm) / WMoOx (200nm) / ITO (150nm) / WMoOx (200nm) / NiVOx (80nm ) / Li(40nm) / ITO(150nm) / WMoOx(200nm) / Li(40nm) / NiVOx(80nm) / ITO(120nm) / Si 3 N 4 (20nm).

[0048] The process of preparing this dimming glass is as follows:

[0049] (1) The substrate is cleaned and dried, laser scribed, then cleaned and dried, and placed in a vacuum sputtering area;

[0050] (2) Deposit the ITO layer on the substrate by means of magnetron sputtering, the target used is an ITO rotating target, the power supply is DC or an intermediate frequency power supply with a frequency of 2000-40000Hz, the power is 1-30KW, and the process gas is argon , deposited at a temperature of 290°C;

[0051] (3) The NiVOx layer is deposited on the ITO layer by magnetron sputtering, the target used is a metal NiV planar target, the power supply is a DC power supply, the power is 1-30KW, and th...

Abstract

The embodiment of the invention discloses dimming glass and a preparation method thereof. The dimming glass comprises a substrate, and a first conductive layer, a first auxiliary dimming layer, a first ion conductor layer, a first main dimming layer, a second conductive layer, a second main dimming layer, a second auxiliary dimming layer, a second ion conductor layer, a third conductive layer, a third main dimming layer, a third ion conductor layer, a third auxiliary dimming layer, a fourth conductive layer; and an outer protective layer which are sequentially formed on one side of the substrate. According to the dimming glass disclosed by the embodiment of the invention, the color regulation and control range of the glass is enlarged, and regulation and control of more colors are realized.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a dimming glass and a preparation method thereof. Background technique [0002] Due to its low-carbon, energy-saving, and color-adjustable characteristics, dimming glass has been gradually applied in many industries such as construction. Switchable glass can continuously and reversibly change the optical properties of the material under the action of an external electric field, so that the color and transparency of the glass can undergo reversible changes, and can realize the regulation and change of multiple colors. However, the current switchable glass has a single color control range and uneven color, which is difficult to meet the needs of industry development. Contents of the invention [0003] In view of the above problems, embodiments of the present invention provide a dimming glass and a preparation method thereof. [0004] Specifically, a dimming glass provided by an e...
