WATER-RESISTANT AND ANTI-CORROSION CERAMIC COATING MATERIAL USING NANOSCALE FLAKES

摘要

The present invention relates to an anti-corrosion coating composition for a metal or concrete structure, comprising a polymer resin, a hardener, ceramic powder and, as a filler material, layered silicates and glass flakes. The length of each of the glass flakes is shorter than the thickness of a coating layer formed by the composition, and the glass flakes are arranged parallel to the coating surface of the coating layer. The above-described coating composition has superior effects of protecting the metal or concrete structure from substances which cause corrosion, and thus has remarkably enhanced anti-corrosion performance. The coating composition of the present invention minimizes the amount of expensive filler material to be used, minimizes the possibility of the occurrence of a pinhole defect in the coating material, achieves improved coating workability and economical advantages, lengthens the lifespan of the metal or concrete structure, and reduces repair and maintenance costs.
