The invention belongs to the technical field of materials, and in particular relates to a hole-type flame-retardant conductive shielding material and a preparation method, comprising a flame-retardant sponge, a conductive metal layer is adhered to the outer surface of the flame-retardant sponge, and the conductive metal layer has holes. In the case of good conductive shielding effect, it also has good flame retardant effect, and the flame retardant grade will not change during use, the flame retardant release speed is fast, and the flame retardant effect is obvious. |
