  Abstract

Silica aerogel/potassium hexatitanate whisker composite coated fabric was successfully prepared by polyacrylate coating, which could further improve the thermal insulation property of the fabric and provide more efficient thermal protection. The results show that with the increase of the proportion of aerogel particles, the thermal insulation property of the coated fabric first increases and then decreases. When the mass ratio of silica aerogel particles to potassium hexatitanate whisker is 3:7, the composite coated fabric has the best thermal insulation performance with thermal conductivity of 0.232 W/(m쨌k). After the heat source irradiated the fabric, the temperature difference of the inner and outer of the coated fabric decreased by 16.1 and 19.35 , respectively, compared with the original fabric, and the composite coated fabric exhibited more than 75% reflectivity in the near-infrared band. Also, in the test of resistance of the coated fabric to molten metal splash, after the coated fabric was poured with 250 g of molten aluminum, the surface of the coated fabric was not adhered by molten aluminum, and the coated fabric was not burned through and remained intact in appearance, and the PVC film attached to the back of the coated fabric was not damaged, the surface texture of PVC film was clear, indicating that the composite coated fabric has a good thermal protection effect.
