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.
