ELECTRIC ANTICORROSION APPARATUS FOR OUTER SURFACE OF STEEL BUILDING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an electric anticorrosion apparatus which is usable in electric anticorrosion of outer surfaces of steel building structures exposed to the atmosphere and is provided with a conductive coating film excellent in water and weather resistances.;SOLUTION: An electric anticorrosion apparatus includes at least one or more anticorrosion coating films 2 and 3 applied to the outer surface of a steel building structure 1 exposed to the atmosphere, a conductive coating film applied to the outermost layer or interlayer of anticorrosion coating films and a power source flowing a DC current with the steel building structure as the cathode and the conductive coating film as the anode, and the conductive coating film is an ion conductive coating film 4 containing, as a composition, a graft polymer including a fluororesin ionomer as the trunk and sulfonate groups in side chains.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
