Beschreibung
Zusammenfassung:The invention relates to a preparation method of a wave-absorbing brick, which is characterized in that an old wave-absorbing material is decomposed, and a soft polyurethane sponge material is impregnated, stirred and coated, so that the material has a decoration function and also can absorb 3.5-2.5 cm of the wavelength of an X frequency band (8-12 GHz); the radar absorption value is less than or equal to 0.03; and the requirement of high frequency band is met. 本发明涉及一种吸波砖的制备方法，其特征是分解陈旧吸波材料，通过浸渍、搅拌加涂布处理软质聚氨酯海绵类材料后，材料具备装饰同时，兼顾对X频段(8-12GHz)波长3.5cm至2.5cm的吸收；其雷达吸收值≤0.03；满足高频段的要求。
