Abstract The polyurethane resin coating material comprises two components of A and B, the component A comprises modified polyester resin, pigment filler, adjuvant and solvent, and the component B comprises addition compound produced by polymerization reaction of polymethylene polyphenyl polyisocyanate and polylol polyether. Because the hydroxyl on the polyester molecule and isocyanic acid radical on the addition compound molecule can be formed into space-network structure with high cross-linking density, so that after said coating material is film-formed, the coating film posseses the excellent corrosion resistance, flexibility, abrasive resistance, strong adhesive force, good permeability and low toxin. Said invention is simple in production method, can save energy source and its cost is low.
