The low expansion heat-resistant fireproof glass disclosed by the invention comprises, in weight percentage, the following components: SiO2 75-85%, B2O3 8-19%, Al2O3 1~5%, Na2O 2-5.5%, K2O 0-3% ZrO2 0 to 3%, ZnO 0 to 3%, MgO 0 to 3.5%, and CaO 0 to 4%. The glass component determined by the invention has a thermal expansion coefficient which is lower than the existing flat glass in the temperature range of 25 ° C to 300 ° C, and is located between 3.1×10 -7 /° C. and 4.0×10 -7 /° C. The Ritter softening point reaches above 820 °C, has good heat resistance, does not burst and soften deformation after being heated for a long time, can effectively prolong the fireproof time, block the spread of fire and reduce the loss. It is equivalent to composite fire-resistant glass in blocking open flame. It has high softening temperature, small thermal expansion coefficient and light weight per unit area. It can be produced on a large scale by using float glass production line.
