Glass, and preparation method and application thereof

Abstract

The invention relates to a glass, and a preparation method and application thereof. The glass comprises, by weight, 56-68% of SiO2, 10-20% of Al2O3, 4-6% of B2O3, 9-15%of Na2O, 3.5-7% of MgO, 0.1-2% of RO and 0.1-3% of ZrO2, wherein the RO is CaO, SrO or BaO, or two selected from the group consisting of CaO, SrO and BaO. The preparation method of the comprises the following steps: sequentially performing mixing, fusing, homogenizing, casting molding, annealing and chemical strengthening on raw materials, wherein the composition of the raw materials allows the prepared glass to have the above composition. The glass of the invention can be applied to liquid crystal displays, camera devices, solar cell substrates and mobile phones. The glass is light in weight, high in hardness, resistant toscratches, high in breaking strength and mechanical strength, and remarkably improved in comprehensive performance.

Description

technical field

[0001] The disclosure relates to glass processing technology, in particular, to a glass and its preparation method and application. Background technique

[0002] Ultra-thin glass substrates are widely used in the electronic information industry due to their advantages of flexibility, light weight, transparency, and good insulation properties, such as liquid crystal displays, camera devices, solar cell substrates, mobile phones, and solar cell substrates, etc. . A major challenge in applying ultra-thin glass substrates to electronic devices lies in the handleability of thin glass sheets. Glass lacks ductility, and the likelihood of cracking is largely dependent on the mechanical strength of the sheet itself. For thin glass, it is currently improved by coating the thin glass with an organic film or a polymer film. However, this method does not achieve the desired increase in strength. In addition, the ultra-thin glass has problems such as breakage, breakage a...
