Abstract

The invention discloses a method for preparing a high-borosilicate anti-explosion glass cover. The high-borosilicate anti-explosion glass cover is prepared from, by mass, 69.5%-73.5% of SiO2, 12.5%-17.5% of B2O3, 5.5%-9.5% of Na2O, 1.5%-4.5% of Al2O3, 0.01%-0.05% of Li2O, 0.1%-0.6% of K2O, 0.1%-0.6% of BaO, 0.1%-0.5% of ZnO and 0%-0.03% of Fe2O3 in cooperation with high-borosilicate glass raw materials. An electric melting furnace with the highest use temperature of 1800 DEG C is used as founding equipment of the high-borosilicate anti-explosion glass cover, the glass raw materials are converted into glass clear liquid, and the founding process of glass is completed through the processes of silicate forming, clarification, homogenizing and cooling; the finished glass is formed through a forming process and toughening treatment in combination with planeness treatment. The method has the advantages of being capable of meeting the quality requirement and safety requirement of explosion-proof glass and has wide development and application prospects.
