一种耐受25KW功率吸波材料的制备方法
本发明涉及耐高功率微波吸波材料生产技术领域，具体公开了一种耐受25KW功率吸波材料的制备方法，包括如下步骤：将过滤海绵浸渍在部分水泥浆料中，并经过烘干得到无机泡沫；再将剩余的水泥浆料浸渍在无机泡沫上，形成水泥无机泡沫并烘干；将烘干后的水泥无机泡沫浸渍在聚丙烯腈溶液中，经过干燥，预氧化，低温碳化，高温碳化，得到成品。该材料具有优良的阻燃性能和耐功率辐射性能，有望成为耐高功率角锥吸波材料发展方向。
The invention relates to the technical field of production of high-power microwave-resistant wave-absorbing materials, and particularly discloses a preparation method of a 25KW power-resistant wave-absorbing material, which comprises the following steps: immersing a filter sponge in a part of cement slurry, and drying to obtain inorganic foam; soaking the remaining cement slurry on inorganic foam to form cement inorganic foam, and drying the cement inorganic foam; the dried cement inorganic foam is soaked in a polyacrylonitrile solution, and a finished product is obtained through drying, pre-oxidation, low-temperature carbonization and high-temperature carbonization. The material has excellent flame retardance and power radiation resistance, and is expected to become the development direction of a high-power-resistant pyramid wave-absorbing material.
