A kind of alkali-containing aluminosilicate glass and its product, strengthening method and application

Abstract

The invention relates to an alkali-containing aluminosilicate glass and its products, strengthening method and application. In the method, the alkali-containing aluminosilicate glass is sequentially carried out twice in a salt bath of sodium nitrate and potassium nitrate at 350-450° C. Ion exchange to obtain a chemically strengthened aluminosilicate glass article; the composition of the glass includes, SiO 2 52%~68%, Al 2 o 3 10%~23%,Na 2 O 8%~13%, Li 2 O 0~6%, P 2 o 5 2%~5%, ZrO 2 0-5%, ZnO 0-3%; the surface compressive stress of the glass product after chemical strengthening is >600MPa, the compression depth of the stress layer is >50μm, the bending strength is >600MPa, and the Vickers hardness is >600MPa; in electronic devices In the application of the invention, the chemically strengthened alkali-containing aluminosilicate glass article of the present invention is included.

Description

technical field [0001] The invention relates to the technical field of flat glass manufacturing, in particular to an alkali-containing aluminosilicate glass and its product, strengthening method and application. Background technique [0002] With the development of modern display technology, a large number of flat panel display products such as LCD monitors, cash machine protection screens, touch screen information inquiry machines and media advertising players have emerged and entered our daily lives.
