The invention relates to aluminosilicate glass, which is prepared from the following components in percentage by mass: 61 percent to 69 percent of SiO2, 7.5 percent to 13 percent of Al2O3, 14 percent to 19 percent of Na2O, 1 percent to 4 percent of K2O, 1 percent to 4.6 percent of MgO, 0.1 percent to 3.5 percent of CaO, 0 percent to 0.8 percent of SrO, 0 percent to 3 percent of ZnO and 0.05 percent to 0.5 percent of ZrO2. Wherein the following formulas are met by taking the mass percent of the components into the formula: (ZrO2 + ZnO + SrO)/Al2O3 is more than or equal to 0.05 and less than or equal to 0.25, and (Na2O + K2O)/(MgO + CaO + SrO) is more than or equal to 3.2 and less than or equal to 4.8. The prepared aluminosilicate glass has relatively high Vickers hardness, the ion exchange degree of the glass and fused salt is appropriate, the prepared chemically-tempered glass has relatively high surface compressive stress and hardness and balanced linear expansion coefficient and Young modulus, and the chemically-tempered glass is easy to bend and deform, not easy to break and relatively good in scratch resistance and weather resistance.

    本申请涉及一种铝硅酸盐玻璃,按照质量百分比,制备原料包括如下组分:61%~69%的SiO2、7.5%~13%的Al2O3、14%~19%的Na2O、1%~4%的K2O、1%~4.6%的MgO、0.1%~3.5%的CaO、0%~0.8%的SrO、0%~3%的ZnO,以及0.05%~0.5%的ZrO2;其中,以组分的质量百分比带入计算,满足如下公式:0.05≤(ZrO2+ZnO+SrO)/Al2O3≤0.25,3.2≤(Na2O+K2O)/(MgO+CaO+SrO)≤4.8。制得的铝硅酸盐玻璃具有较高的维氏硬度,该玻璃与熔盐的离子交换程度合适,制得的化学钢化玻璃的表面压应力和硬度较高、线膨胀系数和杨氏模量均衡,该化学钢化玻璃易弯曲变形、不易破碎,耐划伤和耐候性能较好。
