High-alkali aluminosilicate glass, chemically toughened glass, preparation method and application
The invention relates to high-alkali aluminum-silicon glass, which is characterized by comprising the following components in percentage by mass: 60 to 65 percent of SiO2, 13 to 16 percent of Al2O3, 0.5 to 1.5 percent of ZrO2, 0 to 2 percent of B2O3, 13 to 15 percent of Na2O, 3.5 to 6 percent of K2O and 3.5 to 5 percent of MgO. Wherein K2O/MgO is greater than or equal to 1; after the high-alkali alumina-silica glass is subjected to heat treatment at the temperature of Td-Td + 100 DEG C, the change of the ion exchange depth after chemical tempering is smaller than or equal to 3 microns compared with the ion exchange depth after direct chemical tempering without heat treatment, and Td is the deformation point temperature. The high-alkali aluminum-silicon glass is high in chemical tempering efficiency, can be subjected to secondary hot-working forming without influencing the chemical tempering process efficiency, and is beneficial to reducing the cost, and the prepared chemical tempered glass product is relatively good in mechanical property. The high-alkali aluminum-silicon glass raw sheet is subjected to chemical tempering before and after secondary heat treatment respectively, and the surface stress value change of the prepared chemically tempered glass is less than or equal to 30MPa.
