Abstract

The invention relates to the technical field of glass processing, and provides a glass strengthening method which comprises the following steps: putting an initial glass substrate into a first etching solution for first etching treatment to obtain a first glass substrate; placing the first glass substrate in a salt material for ion exchange treatment to obtain a second glass substrate; the second glass substrate is placed in a second etching solution for second etching treatment, and a third glass substrate is obtained. The method comprises the following steps: passivating microcracks generated in the manufacturing and appearance processing processes of an initial glass substrate through first etching treatment, and then forming an ion exchange layer with a certain depth on the surface of a first glass substrate through ion exchange treatment; and finally, passivating microcracks generated by ion exchange and releasing stress concentration formed by ion exchange through second etching treatment, so that the glass substrate strengthened by the glass strengthening method is good in mechanical property and has very strong impact resistance. In addition, the glass strengthening method is simple in process, easy to control and low in production cost.

Description

technical field [0001] The application belongs to the technical field of glass processing, and in particular relates to a glass strengthening method, a glass substrate and an etching material for glass. Background technique [0002] In recent years, electronic information products have basically been displays with touch panels, such as tablet computers, smart phones, and car screens. There is a layer of protective glass on the outermost layer of the touch screen display, also known as "Cover Glass" cover glass. In order to protect the cover glass, a layer of toughened film will be pasted on the outer screen of the mobile phone. Both cover glass and tempered film are required to have good mechanical properties, and require good impact resistance and bending resistance. [0003] At present, the raw materials of cover glass and high-end tempered film are high-aluminosilicate electronic glass or lithium-aluminosilicate electronic glass. When the raw materials are processed into...
