Abstract

The invention discloses a glass composition. The glass composition comprises, by mole, 40-65mol% of SiO2, 10-22mol% of Al2O3, 3-18mol% of P2O5, 12-20mol%of Na2O and 0.01-5mol%of ZnO. The glass composition has high Young's modulus and is suitable for chemical strengthening process, and glass after strengthening are good in mechanical properties and resistant to damage and dropping. The invention further provides a preparation method and application of the glass composition. The chemically strengthened glass composition has high compressive stress and fracture toughness and is applicable to various touch screen devices, in particular to curved surface display devices.

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. [0003] According to market demand, touch screen cover gla...
