PROBLEM TO BE SOLVED: To prepare a sheet or tape for corrosion protection capable of sufficiently demonstrating the corrosion protection effect even when the sheet or tape is wound around or attached to a rusted surface by impregnating an non- woven fabric with a prescribed quantity of the corrosion protective composition. SOLUTION: In a sheet or tape for corrosion protection, 5∼20 pts.wt. corrosion protective composition is allowed to impregnate 1 pts.wt. non-woven fabric. For example, the corrosion protective composition is prepared by uniformly mixing 45∼55 pts.wt. rough-refined lubricating oil, 45∼55 pts.wt. petroleum wax, 2∼5 pts.wt. synthesized wax, and 1∼3 pts.wt. rust protection additive. The composition of 1kg/m<2> is allowed to impregnate a polyester non-woven fabric of 1.2mm thickness, 300mm width, 10m length, and 100g/m<2> weight to provide a tape for corrosion protection. When the sheet or tape for corrosion protection is wound around or attached to a rusted metallic surface or the like, the corrosion protective composition is adhered to the surface, and infiltrated into the rust even when the rust is present in the surface, demonstrating the corrosion protection effect.
