【Abstract】 Using rutile nano-titanium dioxide with heat reflection properties and the prepared silica aerogel powder as fillers, water-based polyurethane as the matrix, coating is carried out on the surface of high temperature-resistant inorganic fibers（basalt fiber cloth） to prepare a high-temperature resistant fireproof coating. The results show that the coating is closely combined with the fabric, which improves the mechanical and fire-resistant properties of the fabric（including the reflection heat radiation and thermal insulation properties）. The addition of nano-titanium dioxide to the coating enables the coating to obtain good reflection heat radiation performance. When the powder content of SiO₂ aerogel is 10%, the coating obtains the best thermal insulation and mechanical properties.更多还原
