Abstract

PURPOSE: To prevent the reflection of electromagnetic waves in excellent manner with extremely thin thickness, by mixing the mixed magnetic material of ferrite powder and carbonyl iron powder in the weather proof liquid macromolecular material, constituting them into liquid composite magnetic material, and coating it on the surface of the construction such as metallic bridge members.
CONSTITUTION: The mixed magnetic material of ferrite powder and carbonyl iron powder as the electromagnetic wave absorbing material having extremely greater transmission attenuation rate α(dB/cm) and smaller surface reflection, is mixed into the liquid macromolecular material of weather proof, constituting liquid (paint) composite material. Further, the relfection of electromagnetic waves can be prvented by coating this paint on the surface of the construction members such as bridge members, iron tower, and construction members. Thus, the reflection of electromagnetic waves can be prvented in excellent manner with very thin thickness.
