Lightweight high-temperature-resistant interlayer thermal protection material and preparation method thereof
The invention relates to a light high-temperature-resistant interlayer thermal protection material and a preparation method thereof, and belongs to the technical field of preparation of external thermal insulation materials. The method comprises the following steps: punching and hydrophobizing an aerogel heat insulation core layer material; laying fiber fabrics on the upper surface and the lower surface of the hydrophobized aerogel heat insulation core layer material, and sewing through sewing lines to obtain a heat insulation assembly; dipping the heat insulation assembly in aluminum sol, then drying the heat insulation assembly dipped with the aluminum sol at 40-80 DEG C for 4-12 hours, and then drying at 100-150 DEG C for 1-6 hours to obtain a primary densified heat insulation assembly; and performing graded heat treatment on the primary densified heat insulation assembly at more than two different temperature stages to prepare the light high-temperature-resistant interlayer heat protection material. The light high-temperature-resistant interlayer thermal protection material prepared by the method has the characteristics of high temperature resistance, low density, efficient thermal insulation, high structural strength and excellent anti-scouring performance, and can be applied to the field of efficient thermal insulation under high-temperature and high-heat flow.
本发明涉及一种轻质耐高温夹层热防护材料及其制备方法，属于外防隔热材料制备技术领域。所述方法：将气凝胶隔热芯层材料进行打孔和疏水化；将纤维织物铺设在疏水化的气凝胶隔热芯层材料的上下表面，并采用缝合线进行缝合，得到隔热组件；将隔热组件浸渍在铝溶胶中，然后将浸渍有铝溶胶的隔热组件先在40～80℃下干燥4～12h，然后在100～150℃下干燥1～6h，得到初级致密化隔热组件；将初级致密化隔热组件在两个以上不同温度阶段进行分级热处理，制得轻质耐高温夹层热防护材料。本发明方法制得的轻质耐高温夹层热防护材料具有耐高温、低密度、高效隔热、结构强度高，抗冲刷性能优异的特点，可应用在高温、高热流下的高效隔热领域。
