摘要
水泥净浆、水泥砂浆、混凝土等水泥基复合吸波材料的研究是近几年的热点问题,也是解决当前电磁辐射污染的关键技术。吸波材料的性能很大程度上取决于吸波剂本身,本文对各种水泥基材料中吸收剂的种类、数量、性能及匹配特性的研究进行了总结。同时,水泥材料结构致密,需要添加发泡聚苯乙烯(EPS)、粉煤灰、珍珠岩等透波剂来改善阻抗匹配特性。另外,还需要进行多层结构、异形表面等优化设计。在改善吸波性能的同时,还要使材料兼具力学、隔音、隔热等功能。最后,通过总结现有研究中存在的不足,提出了水泥基吸波材料进一步发展的方向。
It is the research issues in recent years about the cement-based electromagnetic wave absorbing materials such as cement paste,cement mortar and concrete. Also it is the key to solve the problem of electromagnetic radiation pollution. The performance of absorbing material depends largely on the absorbing agent itself. In this paper,the research on the type,quantity,performance and match characteristics of the absorbents in the various kinds of cement-based material are summarized. At the same time,because of the compact structure of cement,it is needed to add the wave transparent agent such as the expanded polystyrene（ EPS）,perlite and fly ash to improve the impedance matching characteristics. In addition,optimization designs such as multilayer structure and special-shaped surfaces are also needed to improve the wave absorption performance. the mechanical property,sound and heat insulation and other functions are also need to consider. At last,the problem in current studies and the directions for further researches were suggested.
