Frame-reinforced wave-transparent heat-insulating aerogel material and preparation method thereof
The invention discloses a frame-reinforced wave-transparent heat-insulating aerogel material and a preparation method thereof, and belongs to the technical field of composite materials. The preparation method comprises the following steps: dispersing aluminum oxide nano powder in water, adding an adsorbent solution and wave-transparent-shading dual-functional additive nanoparticles, and uniformly mixing to obtain a precursor mixed solution; putting the ceramic frame into a reaction kettle, adding the precursor mixed solution, enabling the precursor mixed solution to fully soak the ceramic frame, and putting the reaction kettle in a heating environment for reaction to obtain wet gel; taking out the wet gel, removing the wet gel on the surface of the ceramic frame, carrying out solvent replacement by using an organic solvent, and carrying out supercritical drying to obtain aerogel; the aerogel is subjected to heat treatment, and the frame-reinforced wave-transparent heat-insulation aerogel material is obtained. According to the invention, by introducing the wave-transparent and light-shading dual-functional auxiliary agent and the rigid frame structure, the aerogel composite material with good overall formability, high temperature resistance grade, excellent dielectric property and excellent mechanical strength is obtained.
