Cement-based wave-absorbing material and preparation method thereof
The invention discloses a cement-based wave-absorbing material which comprises a cement matrix and a wave-absorbing reinforcement body, the cement matrix comprises concrete, the concrete comprises cement, sand and water, the wave-absorbing reinforcement body comprises biochar and nano ferroferric oxide, and the cement matrix and the wave-absorbing reinforcement body comprise, by mass, 150-250 parts of cement, 1-2 parts of sand and 1-2 parts of water. The invention relates to an environment-friendly brick which comprises the following components in parts by weight: 400-600 parts of sand, 75-125 parts of water, 1-5 parts of charcoal and 10-30 parts of nano ferroferric oxide. Therefore, the combination of the biochar and the nano ferroferric oxide is used as a wave-absorbing enhancing component, so that more electromagnetic waves can be absorbed, and meanwhile, the loss capacity of the cement-based wave-absorbing material is improved by utilizing the dielectric loss capacity of the biochar and the magnetic loss capacity of the nano ferroferric oxide; therefore, the wave-absorbing performance of the cement-based wave-absorbing material is effectively improved.
本发明公开了一种水泥基吸波材料，包括：水泥基体和吸波增强体，所述水泥基体包括混凝土，所述混凝土包括水泥、砂和水，所述吸波增强体为生物炭和纳米四氧化三铁，其中，所述水泥基体和所述吸波增强体之间的质量份配比为：水泥150‑250份，砂400‑600份，水75‑125份，生物炭1‑5份，纳米四氧化三铁10‑30份。由此，本发明通过利用生物炭和纳米四氧化三铁的组合作为吸波增强组分，从而有利于将更多地电磁波“吸入”，同时利用生物炭的介电损耗能力和纳米四氧化三铁的磁损耗能力来提升水泥基吸波材料的耗损能力，进而有效地提升水泥基吸波材料的吸波性能。
