This invention discloses an anti-
corrosion coating for
steel structures in coastal areas, comprising an
epoxy zinc-rich primer layer, an
epoxy micaceous
iron oxide intermediate paint layer, and a
fluorocarbon topcoat layer. The invention also includes a construction process for this anti-
corrosion coating on
steel structures in coastal areas, comprising the following steps: Step 1, pretreatment of the steel structure surface; Step 2, application of the
epoxy zinc-rich primer; Step 3, application of the epoxy micaceous
iron oxide intermediate paint; Step 4, application of the
fluorocarbon topcoat; Step 5, finished
product inspection and touch-up
coating. This invention utilizes a three-layer composite anti-
corrosion coating system consisting of an epoxy
zinc-rich primer, an epoxy micaceous
iron oxide intermediate paint, and a
fluorocarbon topcoat. By introducing a water-based
rust converter to optimize the surface pretreatment process, and combining precise control of key processes such as layered coating and curing, the adhesion between the coating and the steel structure substrate and the overall anti-corrosion durability are significantly improved. It exhibits excellent anti-corrosion performance and is suitable for anti-corrosion treatment of coastal
steel structures such as port terminals, cross-sea bridges, and offshore platforms.
