▎ 摘  要

NOVELTY - A coating for electromagnetic shielding comprises filler and organic carrier which is polyester resin, polycarbonate, polyurethane modified epoxy resin, phenol resin, and acrylic resin, and the filler is greater than or equal to 1 of graphene, flake silver-coated copper powder, spherical silver-coated copper powder and dendritic silver-coated copper powder. Amount of filler is 70-85 wt.%; the reflectivity of the paint is greater than or equal to 60 dB. USE - A coating for electromagnetic shielding. ADVANTAGE - The coating has very good corrosion resistance, and is low cost, environment-friendly and pollution-free. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing coating for electromagnetic shielding which involves (1) preparing an organic carrier; and (2) mixing prepared organic carrier with filler to obtain electromagnetic shielding coating slurry.
