Abstract: The present invention relates to a water-based two-part fluororosilic acid polyurethane anti-corrosion coating, film-forming substances containing 50-70 parts of hydroxyfluororosilic acrylic resin, pigment 20-40 Servings, 1-10 servings of additives, 3-20 servings of deionized water, curing agent parts containing 5-10 servings of water-based polychyanate, 1-5 servings of thinners, membrane substances and curing agent weight ratio of 100: (5-15). The preparation method is: deionized water, additives, pigment dispersion, fine grinding, add water-based hydroxyfluoroelasil acrylic resin, made of film-forming substances and curing agents mixed to make the coating. Advantages are: polysilicae for soft-chain segment synthesis of polysilane-polyurethane insertion copolymer, improve water resistance, corrosion resistance and other properties, shell raw materials including fluoroacrylic monomer, giving the coating film excellent UV and nuclear radiation resistance, flexibility and excellent wear resistance, durability. Paint solubility is good, at room temperature self-drying, non-toxic tasteless, low VOC, coating film adhesion, widely used in large-scale steel structures, bridges, ships and other fields.
