The invention discloses a metal organic framework compound coated composite magnetic wave-absorbing material and a preparation method thereof, the material takes surface oxidized flaky FeSiAl magnetic wave-absorbing powder as an inner core, takes an MOFs organic framework compound as a coating layer, and takes the MOFs organic framework compound as an iron-based framework material MIL-101 (Fe); wherein the mass fraction of the core material is 70-80, the mass fraction of the coating layer material is 20-30, and the sum of the mass fraction of the core material and the mass fraction of the coating layer material is 100. The preparation method comprises the following steps: S1, carrying out ball milling on micron-scale water-atomized FeSiAl magnetic powder to obtain flaky FeSiAl magnetic powder; s2, in an oxygen atmosphere, roasting and then cooling to obtain an inner core material; and S3, dissolving the surface-oxidized flaky FeSiAl magnetic wave-absorbing powder, ferric nitrate nonahydrate ...
