In order to develop a reflective anti-corrosion coating for marine steel structures in oceanic atmospheric zone,acrylic polyurethane was used as the main film-forming material,by adding different proportions of titanium dioxide,a variety of acrylic polyurethane paints were prepared.By testing the adhesion and contrast rate of acrylic polyurethane paint film,the salt spray resistance and artificial weathering resistance of the anti-corrosion layer combined with epoxy zinc rich primer,epoxy micaceous iron oxide intermediate coatings,acrylic polyurethane paints,and rain night reflective glass microbeads were studied,the optimal mass fraction of TiO2 was determined,a new anticorrosion coating with high reverse reflection brightness coefficient was obtained.The results showed that the mechanical and covering properties of acrylic polyurethane paint could be improved by increasing the mass fraction of TiO2,but the additive amount of TiO2 should not be too much,especially for the anticorrosion coating system,that will make some adverse effect on the overall performance of the coating.
