description The invention discloses a shielding and wave-absorbing composite material with a porous structure and a preparation method of the shielding and wave-absorbing composite material. The preparation method comprises the following steps: preparing a non-compact carbon nanotube continuous network aggregate; adding the mixed powder into the non-compact carbon nanotube continuous network aggregate, and rolling to obtain a membrane material; the mixed powder comprises a high-molecular polymer, shielding wave-absorbing particles and foaming powder; and combining one or more layers of membrane materials together, and placing the membrane materials in an environment with the temperature of more than 100 DEG C, so that the high-molecular polymer is melted, the foaming powder is expanded and foamed to form hollow microspheres, and the shielding and wave-absorbing composite material with the porous structure is obtained. The preparation method disclosed by the invention is simple, easy to operate and low in cost, and the pr
