The invention discloses a preparation method of a magnetic MXene wave-absorbing composite material with a corallite structure, which comprises the following steps: etching Ti3AlC2 into an accordion shape by adopting an in-situ etching method, and preparing a Ti3C2Tx single sheet with good morphology through ultrasonic treatment; the preparation method comprises the following steps: preparing Fe3O4 hollow magnetic particles by adopting a hydrothermal method, and carrying out surface modification on the Fe3O4 hollow magnetic particles by utilizing hexadecyl trimethyl ammonium bromide; the preparation method comprises the following steps: preparing a Ti < 3 > C < 2 > T < x > single sheet into a specific spherical MXene/PMMA microsphere by using prepared polymethyl methacrylate as a template through a template method; and assembling the surface-modified HFO and the MXene/PMMA microspheres through electrostatic self-assembly, and then carrying out annealing treatment to remove the template, thereby obtaining the m
