【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。
[Abstract]:The study of cement based composite absorbing materials, such as cement paste, cement mortar and concrete, is a hot issue in recent years and a key technology to solve the current electromagnetic radiation pollution. In this paper, the kinds, quantities, properties and matching properties of absorbents in various cement-based materials are summarized. At the same time, the structure of cement materials is dense, and it is necessary to add foamed polystyrene (EPS), fly ash, and fly ash. Perlite and other wave-permeating agents are used to improve the impedance matching characteristics. In addition, it is necessary to optimize the design of multi-layer structure, special-shaped surface and so on. While improving the absorbing performance, it is also necessary to make the materials have mechanical, sound insulation, heat insulation and other functions. The development trend of cement-based absorbing materials is put forward by summarizing the shortcomings of existing research.
