High strength aluminosilicate glass and chemically toughening process thereof

Abstract

The invention relates to a high-strength aluminate silicate glass and a chemical toughening method thereof, and belongs to the silicate glass field. The glass comprises the following chemical components (weight percent): 55 to 65 weight percent of SiO2, 0.1 to 3 weight percent of B2O3, 6 to 24 weight percent of Al2O3, 3 to 9 weight percent of MgO plus CaO plus BaO plus SrO, 0 to 1 weight percent of ZrO2, 0 to 2 weight percent of ZnO, 0.1 to 0.5 weight percent of Cl2, 0.1 to 1.0 weight percent of Sb2O3, 0.1 to 0.5 weight percent of SO3 and 0.1 to 0.5 weight percent of F2, and belongs to a aluminate silicate glass system. The high-strength aluminate silicate glass is prepared through a known plate glass production method, and then is subjected to the strengthening treatment by adopting the chemical toughening method. The glass has high permeability of visible light, and relatively common soda lime glass, neutral medicine glass and alkali-free high-aluminum glass have good shock resistance property, high scratch resistance property and high durability. The high-strength aluminate silicate glass is applied to the screen surface protection of plasma display products and liquid crystal display products, the protection of touch screens, the screen protection of automated teller machines, and the screen protection of other electronic products (Mobile phones, PDAs and media machines, etc.), thereby effectively preventing the impact and the scratch damage to the glass surface of display products. The high-strength aluminate silicate glass contains no harmful elements.

Description

technical field [0001] The invention relates to glass materials for screen surface protection of electronic display products (plasma display products and liquid crystal display products), glass materials for fireproof and anti-theft doors of buildings, and high-strength glass materials for cash collection windows of banks and hospitals. It can be used in plasma TV, LCD TV, LCD monitor, notebook LCD monitor, cash machine protection screen, touch screen, mobile phone, PDA, PSP, information inquiry machine, media advertising player, and can effectively prevent the impact and scratch on the surface of the display product screen damage, prolong the service life and use effect, and ensure the safety of buildings and cash register systems. Background technique [0002] With the development of modern technology, electronic display products have developed rapidly in the past 10 years, and advanced flat panel display products have emerged in an endless stream, such as plasma display p...

Problems solved by technology

In addition, touch screens, PDAs, and mobile phones often have dangerous operations such as writing, scratching, and impacting on the display screen with fingers, electronic pens, signature pens, and even keys.

In this way, the display screen of electronic display products is often damaged and the surface is rough, which affects the service life of the whole machine and the display effect of the screen.
