The calcium-silicon series fireproof glass disclosed by the invention comprises, in weight percentage, the following components: SiO2 67-75%, Al2O3 1.5-4%, CaO 5-10%, MgO 0.5-3%, R2O 3-13%, ZrO2 is 0.2 to 2.5%, BaO is 2 to 6%, and SrO is 1 to 6%. It is based on the composition of ordinary float glass to make some composition adjustments: replace some MgO with CaO to increase the density and hardness of the glass; the added Sr2+, Ba3+, Zr4+ plasmas are in the network space, and accumulate the surrounding silicon tetrahedron. Increase the tightness of the structure, promote the decrease of the expansion coefficient, and increase the softening point, so as to ensure that the glass has fire resistance in a certain period of time, thereby achieving the purpose of fire prevention. After adjusting the composition of the ordinary float glass, it is consistent with the composition of the ordinary float glass system, and does not affect the molding production by the float process. The glass article melted from this component has a low coefficient of thermal expansion, a high softening point, good fire resistance and good chemical stability.
