一种用于触摸屏的铝硅酸盐玻璃
摘要：
一种用于触摸屏的铝硅酸盐玻璃，配方中各组成成分的质量百分比分别是：55-70%的SiO2，8-20%的Al2O3，9-16%的Na2O，0.5-8%的MgO，0.5-8%的SrO，0.1-5%的P2O5。本发明引入0.1-5%之间的P2O5，对玻璃离子交换性能的改善具有很大的作用。P2O5与Al2O3并用时，玻璃强化效果比较好。利用本发明制的玻璃在熔融的KNO3（400℃-450℃）溶液中，化学强化时间为4-6小时，离子交换深度大于50μm，玻璃表面应力可在较短时间内至少可达720MPa。玻璃表面形成压应力层，压应力层赋予玻璃较高的强度、表面防刮耐划。
摘要（英）：

The invention discloses alumina silicate glass for a touch screen. The alumina silicate glass comprises the following components by mass percent: 55-70% of SiO2, 8-20% of Al2O3, 9-16% of Na2O, 0.5-8% of MgO, 0.5-8% of SrO and 0.1-5% of P2O5. A great effect on improvement of the ion exchange performance of the glass is achieved by introducing 0.1-5% of P2O5, and the glass is relatively good in strengthening effect when the P2O5 and the Al2O3 are simultaneously used. The chemical strengthening time of the prepared glass in molten KNO3 (400-450 DEG C) solution is 4-6 hours, the ion exchange depth is greater than 50 microns, the glass surface stress can be up to at least 720MPa within a short period of time, a compressive stress layer is formed on the glass surface, and high strength and surface scratch resistance of the glass are achieved by the compressive stress layer.
