摘　　要：随着电磁波对环境污染的日益严重,吸波材料的研究和应用越来越受到人们的关注。目前大量生产的只有用于暗室和电子仪器相关的吸波材料,针对环境污染的建筑用吸波材料还处于研发阶段。本文提出一种以内部填充珍珠岩与碳粉混合散料作为吸收材料的空心砖吸波材料,散料中碳粉的体积含量为6%时在2.4-3.85GHz频段内吸收均在25dB以上。该吸波材料具有优良的物理化学以及力学性能,而且价格低廉,可广泛应用于建筑领域,具有极大的经济效益和环保意义。More attention is paid in study and application of microwave absorbing materials as the electromagnetic wave＇s pollution to environment is serious increasingly. Nowadays, microwave absorbers are only used to reduce the interference of electromagnetic wave in chambers or used in the electronic machine. Electromagnetic wave absorbing .materials used in building has been studying for decades and its application in building has not come true yet. An air brick microwave absorbing materials filled with perlite which mixed with carbon black is studied in the paper. From test result, the absorption of this microwave absorb material all above 25dB when the volume content of carbon black is 6% and the frequency bandwidth is 2.4-3.85GHz. With excellent physical chemistry and mechanics capability, the filling microwave absorbing materials could be used in building widely as their low price. This building microwave absorbing materials of air brick filled with perlite have great economic effects and function of environmental protection.
