<p>Disclosed are a paint composition for preventing corrosion and improving long-term durability of iron structure; and a process for forming an aluminum oxide coating layer using the same. The process for forming an aluminum oxide coating layer of the present invention includes steps of (a) preparing a powder mixture consisting of 0.2 to 0.5 % by weight of zinc (Zn) powder, 0.3 to 1.0 % by weight of chromium (Cr) powder, 0.5 to 1 % by weight of nickel (Ni) powder, 0.06 to 0.15 % by weight of phosphorus (P) powder and the balance of aluminum (Al) powder; and (b) uniformly dispersing the powder mixture prepared above into adhesive resin and spraying the dispersed mixture on a surface of the iron structure to form a coating layer. The process for forming an aluminum oxide coating layer of the present invention is an economical process capable of being simply constructed even at normal temperature, and therefore may be effectively used for preventing corrosion and improving long-term durability of iron structure by uniformly forming an aluminum oxide coating layer having excellent physical properties such as adhesion strength to surfaces of iron structures, elongation, flexibility, etc.</p> |
