Abstract

High-temperature fire-resistant materials are required to enhance the fire-related safety of high story buildings. In this study, the thermal protection performance of protective textiles was evaluated, and these materials were based on silica fabrics coated with silicon resins of different formulations. The fabrics with larger coating thickness had higher $t_{12}$ and HTI values, as expectedly. In addition to the positive effect seen after vermiculite addition, the addition of aerogels in to the coating resin improved substantially the fire-proofing performance, even in very small amounts. However, the small additions to the resin caused a rapid rise in resin viscosity and caused spreading problems on the silica fabrics. Therefore, toluene was required as a solvent. All coated samples showed very high thermal stability with very small volume decreases even at temperatures as high as $900^{\circ}C$. The coated silica fabrics with silicon resin are expected to be used as screen shutters in the case of fire.
