Problems solved by technology

[0003] At present, the common smart dimming glass on the market is laminated glass, which is prone to delamination when the pressure is high. At the same time, it faces problems such as high production cost, complicated transportation and installation.
However, the size of single-chip dimming glass is difficult to enlarge, and the width is limited, which hinders the development
Moreover, the etchant and etching process used in the traditional method of preparing haze controllable glass are relatively complicated, and the safety is poor.

preparation example Construction

[0034] In one aspect, the present invention provides a method for preparing glass with adjustable haze, comprising the following steps:

[0035] The soda-lime glass is placed in hydrochloric acid solution with a mass concentration of 10% to 30% to carry out hydrothermal reaction, wherein the temperature of the hydrothermal reaction is 200°C to 240°C, and the time is 0.5h to 3.5h.

[0036] The preparation method provided above uses hydrochloric acid solution as an etchant, and the glass can be etched through hydrothermal reaction. The equipment used in the whole preparation process is simple, the etching process is simplified, the etching time is shortened, the etching efficiency is improved, and the production cost is reduced, and hydrofluoric acid is not required, which is safer and more reliable, and is suitable for batch and industrial production.

[0037] In addition, after the haze controllable glass prepared by the above preparation method is etched, its surface forms a ...

Embodiment 1

[0053] 1) Rinse the ultra-white soda-lime glass with deionized water, and dry it for later use;

[0054] 2) Dilute concentrated hydrochloric acid with a mass concentration of 36% with deionized water to be a hydrochloric acid solution with a mass concentration of 15%;

[0055] 3) Put the glass in step 1) and the hydrochloric acid solution in step 2) in a high-temperature-resistant hydrothermal kettle, and place the hydrothermal kettle in an oven at 220°C to react for 1 hour;

[0056] 4) Take out the hydrothermal kettle, let it stand at room temperature for 1.5h, take out the glass in step 3), wash and dry it, and then the following figure 1 The haze controllable glass shown in (a).

Embodiment 2

[0058] The preparation method of this example is basically the same as that of Example 1, except that the time of hydrothermal reaction is different. Specific steps are as follows:

[0059] 1) Rinse the ultra-white soda-lime glass with deionized water, and dry it for later use;

[0060] 2) Dilute concentrated hydrochloric acid with a mass concentration of 36% with deionized water to be a hydrochloric acid solution with a mass concentration of 15%;

[0061] 3) Put the glass in step 1) and the hydrochloric acid solution in step 2) in a high-temperature-resistant hydrothermal kettle, and place the hydrothermal kettle in an oven at 220°C for 1.5 hours;

[0062] 4) Take out the hydrothermal kettle, let it stand at room temperature for 1.5h, take out the glass in step 3), wash and dry it, and then the following figure 1 The haze controllable glass shown in (b).

Abstract

The invention relates to the technical field of glass, in particular to haze-adjustable glass as well as a preparation method and application thereof. The preparation method of the haze-adjustable glass comprises the following steps that soda-lime glass is placed in a hydrochloric acid solution with the mass concentration of 10%-30% for a hydrothermal reaction, the temperature of the hydrothermal reaction ranges from 200 DEG C to 240 DEG C, and the time ranges from 0.5 h to 3.5 h. According to the preparation method, only the hydrochloric acid solution is used as the etching agent, and the glass can be etched through the hydrothermal reaction. The used equipment is simple, the etching process is simplified, the etching time is shortened, the etching efficiency is improved, and the production cost is reduced. After the haze-adjustable glass is etched, the whole surface of the haze-adjustable glass presents a multi-layer and porous roughened morphology.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a glass with adjustable haze and its preparation method and application. Background technique [0002] Traditional ordinary glass windows lack haze and color adjustable functions, and it is difficult to meet the special needs of home decoration, offices, and public spaces. With the development of science and technology, intelligent dimming glass has been developed. Smart dimming glass, also known as electronically controlled dimming glass, as the name suggests, is a glass that uses electricity to adjust the light transmission state. Electronically controlled dimming glass is actually a liquid crystal material installed between two layers of glass and processed into laminated glass, so that it has the effect of being transparent when it is powered on, and atomized when it is powered off. [0003] At present, the common smart dimming glass on the market is laminated glass, which is...
