Abstract

The invention provides heat-resistant borosilicate flat glass and belongs to the technical field of fireproof glass. The heat-resistant borosilicate flat glass is prepared from, by weight, 78.1-82% of SiO2, 1-5% of Al2O3, 9-14% of B2O3, 3-6% of Na2O, 1-5% of CaO, 0.5-2% of K2O, 0.1-3% of ZrO2 and 0.01-2% of GeO2, wherein the total content of SiO2 and B2O3 accounts for 87.1-92% of the total content of all the materials, and the weight ratio of SiO2 to B2O3 is 5.5 to 8.6. The invention further provides a preparation method of the heat-resistant borosilicate flat glass; compared with current borosilicate flat glass in the market, the heat-resistant borosilicate flat glass has a higher glass softening point and a lower linear expansion coefficient, at the same time, the melting temperature and the molding temperature are relatively low; the glass is easy to manufacture and can serve as the fireproof glass applied in the fire protection field after being tempered.

Description

technical field [0001] The invention belongs to the technical field of fireproof glass, and relates to a fireproof borosilicate flat glass used in buildings, which is borosilicate 4.0 flat glass, and in particular to a heat-resistant borosilicate flat glass and a preparation method thereof. Background technique [0002] Borosilicate flat glass refers to the basic composition of SiO 2 , B 2 o 3 、Na 2 O glass. Borosilicate glass has excellent thermal properties, optical properties, mechanical properties and chemical properties, and is widely used in architectural fireproof glass, instrument glass, utensil cooker glass, photoelectric power source glass and other fields. [0003] There are two types of borosilicate flat glass currently on the market: borosilicate 3.3 glass and borosilicate 4.0 glass. The performance index of borosilicate 3.3 glass is that the glass softening point is about 820°C, and the expansion coefficient is 33×10 -7 / °C, melting temperature 1670°C, mo...
