Problems solved by technology

[0002] At present, 2.5D or 3D glass casings for electronic equipment are usually processed by machining thicker glass or hot-bending flat glass. The above methods not only waste materials, but also can realize the shape and structure Limited, unable to achieve more complex and fine structures and shapes
At the same time, the current glass housing usually needs to be used in combination with the metal middle frame, and it is still not possible to fully realize the all-glass housing, and the metal middle frame will have a certain electromagnetic shielding effect, which is not conducive to signal transmission
[0003] Therefore, the current method of preparing the shell still needs to be improved

Embodiment 1

[0077] At room temperature, put the first glass piece and the second glass piece in acetone, peracetic acid solution or calcium hypochlorite solution for 30 minutes, take them out, wash them with pure water, and then dry them. Put the cleaned first glass piece and the second glass piece into a mixed solution of ammonia water and hydrogen peroxide with a volume ratio of (1:1), treat at 40°C for 1 hour, wash the residual solution on the surface with pure water for 10 minutes, and then blow it. Dry, the surface of the glass part is activated. The surface roughness of the glass surface before activation was 0.543 nm.

Embodiment 2

[0079] At room temperature, put the first glass piece and the second glass piece in acetone, peracetic acid solution or calcium hypochlorite solution for 30 minutes, take them out, wash them with pure water, and then dry them. Put the cleaned first glass piece and the second glass piece into a mixed solution of ammonia water and hydrogen peroxide (1:2), treat at 40°C for 50 minutes, wash with pure water for 10 minutes, and then blow dry the surface of the glass piece. get activated. The surface roughness of the glass surface before activation was 0.285 nm.

Embodiment 3

[0081] At room temperature, put the first glass piece and the second glass piece in acetone, peracetic acid solution or calcium hypochlorite solution for 30 minutes, take them out, wash them with pure water, and then dry them. Put the cleaned first glass piece and the second glass piece into a mixed solution of ammonia water and hydrogen peroxide (1:3), treat at 40°C for 40 minutes, wash with pure water for 10 minutes, and then blow dry the surface of the glass piece. get activated. The surface roughness of the glass surface before activation was 0.369 nm.

Abstract

The invention provides a shell and a preparation method thereof, a display device and terminal equipment. Specifically, the preparation method of the shell includes: conducting cleaning treatment on at least part of the surface of a first glass piece and at least part of the surface of a second glass piece so as to form clean surfaces; utilizing an alkaline activation solution to conduct activation treatment respectively on the clean surface of the first glass piece and the clean surface of the second glass piece so as to form activated surfaces; contacting the activated surface of the first glass piece with the activated surface of the second glass piece to compound the first glass piece and the second glass piece together, thus obtaining the shell. The method is simple and convenient tooperate and easy to implement, a new saturated chemical bond is formed between the first glass piece and the second glass piece that are subjected to activation treatment, the binding force is high, the formed shell has good strength, high internal uniformity, and no bubble or magical color, also the shell has a smooth and flat surface, excellent optical performance, high light transmittance, andbeautiful appearance.

Description

technical field [0001] The present invention relates to the technical field of casing processing, and in particular, relates to a casing and a preparation method thereof, a casing, a display device, and a terminal device. Background technique [0002] At present, 2.5D or 3D glass casings for electronic devices are usually processed by machining thicker glass or hot-bending flat glass. Limited, can not achieve more complex and fine structure and shape. At the same time, the current glass casing usually needs to be used in combination with a metal middle frame, and it is still not possible to fully realize an all-glass casing, and the metal middle frame will have a certain electromagnetic shielding effect, which is not conducive to signal transmission. [0003] Therefore, the current method of preparing the shell still needs to be improved. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a ...
