Abstract

The invention provides a method for preparing curved glass, comprising: providing flat glass and side glass, and coating a SiO on the sides to be bonded of the flat glass and side glass respectively 2 layer, so that the sides of the flat glass and side glass are flattened; the flattened flat glass and side glass are vacuum thermally bonded, and then CNC cutters are used to cut the bonded glass combination to Get the curved glass of the desired shape. In the present invention, before vacuum thermal bonding is carried out on the glass substrates used for preparing curved glass, a SiO 2 Layer, which can reduce the surface roughness of the glass substrate and improve its flatness, thereby avoiding or reducing the occurrence of air bubbles during bonding, and improving the bonding strength.

Description

technical field [0001] The invention relates to the technical field of curved glass, in particular to a method for preparing curved glass. Background technique [0002] Curved glass refers to glass with curved edges. Using curved glass on the touch screen of electronic devices such as mobile phones can improve the overall visual effect of the screen and body, making it more visually appealing and enhancing the feel of the touch. [0003] The existing curved glass is usually prepared by directly adopting vacuum thermal bonding technology to the flat glass and the side glass, or fixing it by glue, and then adopting CNC (Computer Numerical Control, computer numerical control machine tool) technology to bond the surrounding glass The redundant structure is cut and removed, and then the surface is polished to obtain the curved glass of the desired shape (single-sided / opposite-sided / four-sided curved structure). The cost of the preparation process is low, the design of the curved...
