Embodiment 1

[0032] A preparation process for foldable flexible glass, specifically comprising the following steps:

[0033] S1, the first chemical thinning: use the top spraying process to carry out the first chemical thinning of the glass, and thin the glass to a thickness of 0.05mm; in order to improve the processing efficiency, this embodiment chemically thins 50 pieces of glass at the same time ;

[0034] Before the first chemical thinning of the glass, it is glued to the substrate, and the first chemical thinning is carried out on the glued glass; wherein, aluminosilicate with a thickness of 0.7mm and the same size as the glass is selected. Salt glass is the substrate, and one side of the substrate is covered with an acid-proof film by a laminating machine for acid-proof treatment. UV curing to obtain glued glass.

[0035] S2. Laser cutting: use laser cutting with a pulse width of 600 femtoseconds to obtain glass with a target size (100×150mm); wherein, degumming treatment is perfo...

Abstract

The invention discloses a preparation process of foldable flexible glass. The process of combining two times of chemical thinning with laser cutting and chemical tempering is adopted. The method specifically comprises the steps of first-time chemical thinning, laser cutting, second-time chemical thinning and chemical tempering. Wherein the second-time chemical thinning adopts a vertical soaking method to thin the glass, and meanwhile, defects generated on the edge of the glass after laser cutting are eliminated. According to the preparation process, repeated dispensing and lamination treatment are not needed, so that the process is simplified, the material consumption is reduced, the straight-through yield of the flexible glass with the thickness of less than or equal to 0.05 mm can be effectively improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of flexible glass preparation, in particular to a preparation process of foldable flexible glass. Background technique [0002] With the launch of a series of new products such as flexible displays and flexible solar cells, flexible glass, as a new type of special glass, has become a research hotspot at home and abroad. Flexible glass refers to flat glass with a thickness of ≤0.1mm and good bending toughness. Flexible glass not only has the hardness, transparency, heat resistance, and stable mechanical and chemical properties under oxidation and light conditions of ordinary glass, but also has the characteristics of bendability, light weight, and processability. [0003] The preparation methods of flexible glass mainly include primary forming method and secondary forming method. The primary forming method mainly includes the overflow down-draw method, the slit down-draw method and the float method; the secondary for...
