Fire Resistance and Heat Insulation Properties of Perfusion Type Fireproof Glass

To improve the fire resistance heat insulation performance of fireproof glass, the effect of fire resistance performance of fireproof glass interlayer rubber was explored by adding borax to the potassium polysilicate-based slurry. Characterization and testing were carried out by preparing a silica sol mixture, and the transmittance, S/B-0.45H and interlayer thermodynamics, fire resistance and expansion ratio were further analysed. The results showed that the addition of borax affected the transmittance of perfusion type fireproof glass. As the borax content increased, the light transmittance of the fireproof glass decreased. The effect of borax on the expansion efficiency of potassium polysilicate was obvious. In summary, Borax can improve the fire resistance of polysilicate type perfusion fireproof glass. As the borax content increases, the fire resistance of the fireproof glass increases.
