STEEL PLATE FOR HIGHLY CORROSION-RESISTANT FUEL TANK

摘要

A steel plate for highly corrosion-resistant fuel tanks which comprises: a steel plate; deposit layers made of or consisting mainly of zinc as the lowermost layers respectively on both sides of the plate; chemical conversion coatings formed respectively on the lowermost layers; an organic resin film formed on one of the chemical conversion coatings and comprising particles of aluminum and nickel metals and an amine-modified epoxy resin; and an organic resin film formed on the other chemical conversion coating and comprising a resin having at least one functional group selected among hydroxyl, isocyanate, carboxyl, glycidyl, and amino groups, silica, and a lubricant. It is excellent in corrosion resistance and suitability for press working, resistance welding, and brazing and is useful as a steel plate especially for alcohols and gasohols.
