preparation example Construction

[0043] In order to describe the preparation method of the insulating glass 100 in detail, the electrochromic glass 10 formed by coating a large plate (large area) glass substrate is taken as an example to illustrate the preparation process of the insulating glass 100, which includes the following steps.

[0044] 1. Large plate (large area) substrate coating

[0045] Combined with the current large-area glass coating process, after the glass substrate is cleaned and dried, it enters the vacuum coating line, is coated, and leaves the vacuum coating line to complete the large-scale coating process. The coating process of each step is as follows:

[0046] 1. Deposit an ion barrier layer on a large-area flat substrate, and the material of the ion barrier layer can be SiO x ;

[0047] 2. A bottom transparent conductive layer is deposited on the ion barrier layer, and the material of the bottom transparent conductive layer can be AZO;

[0048] 3. Deposit an electrochromic layer on...

Abstract

The invention relates to electrochromic glass, hollow glass and preparation methods thereof. The electrochromic glass comprises a substrate as well as an ion barrier layer, a bottom transparent conducting layer, an electrochromic layer, a first lithium ion conductor layer, an auxiliary electrode layer, a second lithium ion conductor layer, a top transparent conducting layer and a protective layer which are sequentially formed in the substrate. According to the electrochromic glass, the hollow glass and the preparation methods thereof, problems of low conformance rate and incapability of totally releasing productivity in a conventional process are solved.

Description

technical field [0001] The invention relates to an energy-saving glass, in particular to an electrochromic glass with a new structure, a hollow glass and a preparation method thereof. Background technique [0002] Insulating glass is a new type of building material with good heat insulation, sound insulation, beauty and practicality. Existing insulating glass generally includes two or more layers of plate glass, and a heat-insulating and sound-insulating cavity is formed between the plate glass. Two or more pieces of insulating glass are bonded together with a high-strength, high-air-tight composite adhesive and a spacer, and the spacer is filled with a desiccant, which can ensure sound and heat insulation. Keep the cavity dry. [0003] Among them, some flat glass uses electrochromic glass. [0004] Electrochromism refers to the phenomenon that the optical properties of materials (reflectivity, transmittance, absorptivity, etc.) undergo stable and reversible changes under...
