Abstract

The invention discloses an ultra-thin chemically strengthened glass and a preparation method thereof. In the present invention, the glass sample is soaked in the microwave hydrothermal environment of the ion exchange solution for ion exchange treatment, thereby obtaining chemically strengthened glass; the ion exchange solution is an aqueous solution made of potassium nitrate, potassium silicate, rubidium nitrate and cesium nitrate , in an ion exchange solution, K + The concentration is 27~40mol / L, Rb + The concentration of Cs is 0.5~4mol / L, Cs + The concentration is 1.5~4.5mol / L; the molar ratio of potassium nitrate to potassium silicate is 1:0.002~0.05; the microwave hydrothermal temperature is 300℃~350℃, and the ion exchange time is 4~10h. Compared with the molten salt method, the invention produces less pollution and energy waste; the stress depth of the chemically strengthened glass prepared by the invention reaches more than 45 ΞΌm; the surface stress intensity reaches more than 700 MPa, and has good light transmission.

Description

technical field

[0001] The invention relates to the technical field of strengthened glass, in particular to an ultra-thin chemically strengthened glass and a preparation method thereof. Background technique

[0002] Ultra-thin glass usually refers to glass with a thickness below 1.5mm. At present, ultra-thin glass has been widely used in the field of electronic information display, as the protective glass of display devices such as smartphones and tablet computers, but these electronic products fall when used or carried, causing the glass to break, so ultra-thin glass needs to be strengthened . The introduction of surface compressive stress on the glass surface can effectively improve its strength, and the introduction of surface compressive stress can be achieved by physical strengthening and chemical strengthening. The physical strengthening method can be divided into gas medium strengthening method, liquid medium strengthening method, particle strengthening method and m...
