Zinc phosphate primer, micaceous iron oxide intermediate paint and topcoat with different colors were prepared with epoxy modified silicone resin as paint base. The thermal resistance of different coatings, and the corrosion resistance and thermal resistance of the composite coatings obtained from zinc phosphate primer and micaceous iron oxide intermediate paint combined with topcoats with various colors were studied. The results showed that the coating obtained from zinc phosphate primer and micaceous iron oxide intermediate paint combined with chromium oxide green topcoat has good high temperature resistance and corrosion resistance. The composite coating after baking at 350℃ for 3 h has following properties: impact strength ≥40 kg·cm, adhesion≤grade 2, flexibility≤2 mm.
