The invention relates to the technical field of electromagnetic shielding materials, and discloses a Co3O4-carbon nanotube modified polyurethane composite electromagnetic shielding material. Raw materials of the composite electromagnetic shielding material comprise magnetic cobaltosic oxide, single-walled carbon nanotubes, triallyl isocyanurate, polyurethane resin, an alkalizing agent, a foaming agent and a dispersing agent, wherein the magnetic cobaltosic oxide is of a spinel structure, and the polyurethane is polyether type polyurethane. According to the composite electromagnetic shielding material, the polyurethane is used as a matrix of the electromagnetic shielding material; the thickness and the weight of the electromagnetic shielding material are reduced and the production cost is reduced; the alkalized single-walled carbon nanotubes are added to modify the polyurethane, basic groups in the alkalized single-walled carbon nanotubes and carbonyl groups of the triallyl isocyanurateform hydrogen bonds, and the triallyl isocyanurate is thermally crosslinked with the polyurethane, so that the effects of heat resistance, impact toughness and mechanical properties of hardness of the composite electromagnetic shielding material are enhanced.
