摘　　要：根据电磁波吸收原理，对建筑隔热材料进行功能化改造，通过λ/4模型设计和理论模拟分析，成功制备出珍珠岩泡沫水泥电磁波吸收板材。实验表明，2~4GHz频段，电阻膜采用380Ω/，厚度为1.20cm的吸波板材，在3GHz附近有最大吸量-25dB，反射率在-10dB以下带宽达到65%；同样采用380Ω/电阻膜，厚度为1.50cm的材料，成功实现了2.45GHz吸波材料的制备。新材料可用于无线局域网的电磁干扰防护及建筑室内电磁辐射污染控制。According to the principle of electromagnetic wave absorption, functionally thermal insulating materials for building are reformed. Through designing and theoretically simulating of the λ/4 model, perlite foam cement panels for electromagnetic wave absorption are successfully prepared. The results show that there is a maximum absorption of-25dB at 3GHz and 65%of bandwidth below-10dB under the conditions of 380Ω/resistive film and specimen thickness of 1.20cm. When the resistive film is 380Ω/and specimen thickness is 1.5cm, 2.45GHz absorbing materials are successfully designed and prepared. The new materials can be used for electromagnetic interference protection for WLAN and indoor electromagnetic radiation pollution control.
