Abstract

The invention discloses a glass composition and a preparing method and application thereof. The total weight of the glass composition is calculated as 100%, wherein the glass composition comprises 45-65wt% of SiO2, 12-25wt% of Al2O3, 0.5-15wt% of P2O5, 9-17wt% of Na2O, 0.1-5wt% of MgO, 0.1-5wt% of Y2O3 and unavoidable impurities; the invention further provides a preparing method and application of the glass composition in the preparation of a touch screen and / or a solar battery. The glass composition is loose in structure, suitable for chemical strengthening and processing, through short-time chemical strengthening, the deeper strengthening depth and the higher compressive stress and Vickers hardness can be obtained, and the anti-dropping ability of glass is improved.

Description

technical field [0001] The present disclosure relates to the technical field of strengthened glass, in particular, to a glass composition and its preparation method and application. Background technique [0002] Glass has always been an indispensable material in the development of display technology. With the development of display technology, changing the composition of the glass surface through chemical strengthening can improve the strength of the glass. Glass is more used in the protection of display devices. At present, tablet computers, LCD TVs, mobile phones, digital cameras, etc. are equipped with touch screens, and during use, the touch screen cover glass is prone to contact and friction, and inadvertent scratches and touches, the resulting scratches directly The surface of the touch screen is rough and the smoothness is reduced, which affects the use effect and is more likely to cause the screen to break. And when the portable device falls, the cover glass bears t...
