摘要：In this paper, the shielding effectiveness of the electromagnetic shielding composite coating with copper powder and silver coated copper powder as the base material was tested by preparing the polyurethane matrix with 0.95~1.01 isocyanate index and adding flaky ferro-silico-aluminium powder. The field comparison experiment shows that the silver-clad copper-based electromagnetic shielding composite coating has a good efficiency of power frequency electromagnetic shielding, which is up to 30.71dB. It has a broad application prospect in the field of electromagnetic protection of power transmission and transformation facilities.
