Preparation method of low-cost environment-friendly microwave absorber
The invention discloses a preparation method of a low-cost environment-friendly microwave absorber. The differentiation characteristics of two types of solid waste formula elements such as a manganese-zinc ferrite magnetic core and wave absorption are combined; the structure that the grain boundary of the manganese-rich magnetic core material is filled with the zinc-rich wave-absorbing material isdesigned, high-energy mechanical alloying is combined with segmented heat treatment, diffusion doping is conducted on a low-loss magnetic core solid waste grain interface, and the electromagnetic loss and the wave-absorbing performance of the absorber are enhanced. Meanwhile, according to the design, growth and diffusion of the fine-grain wave-absorbing material on the large-grain interface of the magnetic core material are utilized, the common problem of air gaps of the solid waste-based microwave absorber is effectively solved, the effective microwave absorption performance of the solid waste-based microwave absorber is improved, and meanwhile the mechanical property of the absorber is also enhanced. Ferrite solid waste is completely used as a raw material, the preparation cost is extremely low, and the method is suitable for practical and environment-friendly microwave absorption products.
本发明公开了一种低成本环保微波吸收体的制备方法，通过结合锰锌系铁氧体磁芯和吸波等两类固废配方元素的差异化特点，设计了富锌吸波料填充富锰磁芯料晶界的结构，并利用高能机械合金化结合分段热处理，对低损耗的磁芯固废晶粒界面进行扩散掺杂，增强吸收体的电磁损耗和吸波性能。同时，本发明的设计利用细晶吸波料在磁芯料大晶粒界面的生长和扩散，有效解决了固废基微波吸收体的空气隙通病，提升了其有效微波吸收性能，同时也增强了吸收体的力学性能。本发明完全采用铁氧体固废作为原料，制备成本极低，适合实用环保微波吸收产品的应用。
