Manufacturing method of wave-absorbing pyramid for cement inorganic foam microwave anechoic chamber

The invention relates to the technical field of wave-absorbing functional materials, in particular to a manufacturing method of a wave-absorbing pyramid for a cement inorganic foam microwave anechoic chamber. The method comprises the following steps of: firstly, preparing cement slurry, then mixing polystyrene foam beads with the cement slurry to form slurry, then injecting the slurry into a mold to prepare a molded triangular pyramid, then soaking the molded triangular pyramid in an alkaline aqueous solution to dissolve the polystyrene foam beads, retaining a cement skeleton to form an inorganic foam triangular pyramid, and finally, soaking the inorganic foam pyramid in absorption liquid to obtain an inorganic foam pyramid wave-absorbing material. The material has excellent flame retardance and power radiation resistance, and meanwhile, the manufacturing cost is greatly reduced. 本发明涉及吸波功能材料技术领域，具体涉及一种水泥无机泡沫类微波暗室用吸波角锥的制造方法；首先，制备出水泥浆料，然后，将聚苯乙烯泡沫珠粒与水泥浆料混合，形成浆料，然后注入模具中制备为成型三角锥，然后，将成型三角锥浸泡在碱性水溶液中，溶解聚苯乙烯泡沫珠粒，保留水泥骨
