▎ 摘　　要

NOVELTY - The wave-absorbing material has a wave-transmitting layer, a bonding layer and a wave-absorbing layer which are sequentially stacked. The bonding layer is made of water-based silicon-aluminum gel. The wave-absorbing layer is composed of high-temperature-resistant wave-absorbing fiber cloth. The high-temperature-resistant wave-absorbing fiber cloth comprises fiber cloth and a wave-absorbing coating coated on the surface of the fiber cloth. The wave-absorbing coating is formed by curing wave-absorbing coating. The wave-absorbing coating comprises a radar wave-absorbing agent, aqueous silicon-aluminum gel and deionized water. The radar absorbing agent comprises graphene, conductive carbon black, carbon nanotubes, silicon carbide, zinc oxide whiskers, and porous carbon. The fiber cloth comprises glass fiber cloth, quartz fiber cloth, or basalt fiber cloth. USE - Wave-absorbing material. ADVANTAGE - The prepared wave-absorbing material not only has broadband stealth performance, but also has the temperature resistance of over 800 ℃, and can be kept stable for a long time in a high-temperature environment of 800-1000 ℃.. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the wave-absorbing material.
