Problems solved by technology

[0002] Glass is more difficult to process due to its high brittleness. It is more difficult to process it into some complex and fine shapes and structures. At present, in order to expand the application range of glass and meet the requirements of some specific fields, multiple glass parts can be composited in They are used together to form a glass composite body, so that the obtained composite body not only has the properties of glass, but also can realize complex and fine shapes, but the currently obtained glass composite body, or the bonding strength cannot meet the use requirements, or the strength can meet the requirements, However, the glass will be deformed during the processing, which will seriously affect the appearance quality and optical performance of the glass composite, and if the deformation is uneven, it will cause serious surface distortion and unevenness, which will limit the use of the glass composite.
[0003] Therefore, the current related technologies of glass composites still need to be improved.

Embodiment 1

[0102] Will K 2 Cr 2 o 7 Dissolve 60 g in 270 g of water, slowly add 44 ml of concentrated sulfuric acid, soak the first glass piece and the second glass piece with the prepared mixed acid solution (2 hours at room temperature or 30 minutes at 50° C.). After taking it out, wash off the residual chromium ions on the surface with 10% nitric acid washing solution. Rinse with pure water for 10 minutes and then blow dry to activate the surface of the glass piece. The surface roughness of the glass surface before activation was 0.612 nm.

Embodiment 2

[0104] Will K 2 Cr 2 o 7 Dissolve 20 g in 270 g of water, slowly add 44 ml of concentrated sulfuric acid, soak the first glass piece and the second glass piece with the prepared mixed acid solution (6 hours at room temperature or 150 minutes at 50° C.). After taking it out, wash off the residual chromium ions on the surface with 10% nitric acid washing solution. Rinse with pure water for 10 minutes and then blow dry to activate the surface of the glass piece. The surface roughness of the glass surface before activation was 0.592 nm.

Embodiment 3

[0106] Will K 2 Cr 2 o 7 Dissolve 30 g in 270 g of water, slowly add 44 ml of concentrated sulfuric acid, soak the first glass piece and the second glass piece with the prepared mixed acid solution (5 hours at room temperature or 120 minutes at 50° C.). After taking it out, wash off the residual chromium ions on the surface with 10% nitric acid washing solution. Rinse with pure water for 10 minutes and then blow dry to activate the surface of the glass piece. The surface roughness of the glass surface before activation was 0.589 nm.

Abstract

The invention provides a glass composite and a preparation method thereof, a shell, a display device and terminal equipment. Specifically, the glass composite comprises a first glass piece and a second glass piece that have at least part of surfaces in connection, and a contact surface is defined at the contact position of the first glass piece and the second glass piece, wherein no visible gap exists in the contact surface, and when the glass composite contacts an acid solution, the glass composite is suitable for forming a gap at the contact surface. Therefore, the glass composite can be formed by compounding at a low temperature, the preparation conditions are mild and are easy to realize, also the preparation cost is low, the composite glass body has excellent compound effect, also hasbonding strength, appearance effect and optical performance suitable for application to electronic equipment, and can realize a complex and fine special-shaped structure. In addition, the corrosion speed of the acid solution to the contact surface is higher than the corrosion speed of hydrofluoric acid on the first glass piece and the second glass piece, therefore the existence of a bonding interface can be effectively detected.
