Embodiment 1

[0034] A preparation method of ultra-thin glass, comprising the following steps:

[0035] (1) Take the glass, soak the glass in the thinning etchant, and perform the first thinning treatment on the glass;

[0036] (2) Grinding and polishing the thinned glass on both sides;

[0037] (3) Lay the glass that has been ground and polished on both sides on the carrier glass, and then soak it in the thinning etchant, and perform the second thinning treatment on the glass to obtain ultra-thin glass.

[0038] Further, the cross-sectional area of ​​the carrier glass is the same as that of the glass that has been ground and polished on both sides, and its thickness is thicker than that of the glass that has been ground and polished on both sides.

[0039] Further, in the step (1) and step (3), the thinning etchant includes the following raw materials in parts by weight: 1 part of hydrofluoric acid, 5 parts of ammonium fluoride, and 94 parts of water.

[0040] Further, in the step (1), t...

Embodiment 2

[0050] In this embodiment, a method for preparing ultra-thin glass includes the following steps:

[0051] (1) Take the glass, soak the glass in the thinning etchant, and perform the first thinning treatment on the glass;

[0052] (2) Grinding and polishing the thinned glass on both sides;

[0053] (3) Lay the glass that has been ground and polished on both sides on the carrier glass, and then soak it in the thinning etchant, and perform the second thinning treatment on the glass to obtain ultra-thin glass.

[0054] Further, the cross-sectional area of ​​the carrier glass is the same as that of the glass that has been ground and polished on both sides, and its thickness is thicker than that of the glass that has been ground and polished on both sides.

[0055] Further, in the step (1) and step (3), the thinning etchant includes the following raw materials in parts by weight: 0.8 parts of hydrofluoric acid, 4 parts of ammonium fluoride, and 90 parts of water.

[0056] Further,...

Embodiment 3

[0066] In this embodiment, in the step (2), the thinning etchant includes the following raw materials in parts by weight: 0.12 parts of hydrofluoric acid, 6 parts of ammonium fluoride, and 98 parts of water.

[0067] Further, in the step (1), the first thinning treatment is performed on the glass to reduce the thickness of the glass to 0.16 mm.

[0068] Further, in the step (3), the glass is subjected to a second thinning treatment to reduce the thickness of the glass to 0.03 mm, and a glass with a thickness of 0.03 mm is prepared.

[0069] Further, in the step (2), the specific operation of grinding and polishing includes the following steps:

[0070] A1. Polishing: place the glass in a polishing machine and use polishing liquid to polish;

[0071] A2. Ultrasonic cleaning: Ultrasonic cleaning of polished glass;

[0072] A3. Drying: Dry the ultrasonically cleaned glass.

[0073] Further, in the step A1, the polishing liquid is composed of the following raw materials in part...

Abstract

The invention relates to the technical field of glass, in particular to a preparation method of ultra-thin glass, comprising the following steps: (1) taking glass, soaking the glass in a thinning etchant, and performing the first thinning treatment on the glass; (2) The thinned glass is double-sided grinding and polishing; (3) The double-sided grinding and polishing glass is attached to the carrier glass, and then soaked in the thinning etchant, and the glass is subjected to the second thinning treatment to make Get ultra-thin glass. The ultra-thin glass preparation method of the present invention can prepare ultra-thin glass with thin thickness, strong light transmission, good softness, and high touch sensitivity. It is used to prepare ultra-thin glass with a thickness of 0.03mm.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a method for preparing ultra-thin glass. Background technique [0002] With the development of society and the advancement of technology, glass has been widely used in the electronics industry, such as optical glass film or tempered glass, and people's requirements for glass, especially ultra-thin glass, are also increasing. The thickness of ultra-thin glass films on the existing market is usually 0.10-0.33 mm, for example, the thickness is 0.33, 0.22, 0.15 or 0.10 mm. However, the ultra-thin glass of the above-mentioned thickness has low toughness and softness, resulting in a relatively small degree of bending, and cannot completely wrap the screens with curved edges such as mobile phones or other electronic products. Touch sensitivity needs to be further improved. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the o...
