The invention relates to an electromagnetic shielding composite material door plate structure and a preparation method thereof. The door plate structure comprises a core material structure and a skin structure. The core material structure comprises a conductive metal structure and a foam core material structure, the conductive metal structure comprises a first conductive metal layer and a second conductive metal layer, and the foam core material structure comprises a first foam core material layer and a second foam core material layer; the skin structure comprises an outer surface skin layer and an inner surface skin layer; the outer surface skin layer, the first conductive metal layer, the first foam core material layer, the second conductive metal layer, the second foam core material layer and the inner surface skin layer are sequentially arranged in the direction from the outside of the cabin to the inside of the cabin. The shielding effectiveness can be larger than or equal to 60 dB at the L frequency band and the X frequency band, meanwhile, the good mechanical property is achieved, the mass is light, and seawater corrosion resistance is achieved.
