    Alkaline aluminosilicate glass as well as preparation process and application thereof

    Freier Zugriff

    The invention discloses alkaline aluminosilicate glass as well as a preparation process and application thereof. The alkaline aluminosilicate glass is prepared from the following raw materials in percentage by mass: 58 to 65 percent of SiO2, 13 to 15 percent of Al2O3, 12 to 15 percent of Na2O, 0 to 6 percent of K2O, 3 to 5 percent of alkaline earth metal and 0 to 1 percent of ZrO2. Moreover, the pressure stress of the glass is CS, and CS is more than or equal to 700Mpa and less than or equal to 800Mpa; the depth of a compressive stress layer of the glass is DOL, and the DOL is greater than or equal to 30 [mu] m and less than or equal to 40 [mu] m; the impact resistance energy of the glass is CT, and the CT meets the condition that CT is larger than or equal to 0.8 J. And the glass has higher glass stress and glass compressive stress layer depth and excellent impact resistance. When a car window made of the alkaline aluminosilicate glass is broken, the state of the car window meets the national safety requirement for car window glass.
