The invention belongs to the technical field of glass, and particularly relates to medium-aluminum glass as well as a preparation method and application thereof. Wherein the medium aluminum glass comprises the following components in percentage by mass: 59%-66% of SiO2, 13%-18% of Na2O, 5%-8% of K2O and 3%-8% of MgO on the basis that the total amount of the medium aluminum glass is 100%. According to the medium-aluminum glass provided by the invention, through coordination and cooperation of all the components and the mass percentage content thereof, the medium-aluminum glass not only has lower softening point temperature, but also has better thermoplasticity in the application process. And after strengthening, the depth of a stress layer can reach more than 30 microns, so that an effective blocking effect is formed on the original Griffius microcracks on the surface of the glass, and cracks caused by external impact and glass breakage caused by crack propagation caused by the cracks can also be prevented.

    本申请属于玻璃技术领域,尤其涉及一种中铝玻璃及其制备方法和应用。其中,以所述中铝玻璃的总量为100%计,包括质量百分含量的组分:59%~66%的SiO2,13%~18%的Na2O,5%~8%的K2O,3%~8%的MgO。本申请提供的中铝玻璃,通过各组分及其质量百分含量的协调配合作用,使中铝玻璃不仅具有较低的软化点温度,中铝玻璃在应用过程中有较好的热塑性。而且强化后,应力层深度可达到30μm以上,对玻璃表面原有的“格里菲斯微裂纹”形成有效的封堵作用,对外部冲击造成的裂纹及其引发的裂纹扩展导致的玻璃破碎,也能起到阻止作用。
