Abstract: An ultrathin fire resistant steel structure is prepared by using P-resin as base material and ammonium polyphosphate pentaerythritol and melamine as intumescent flame re-tardant systems in addition to titanium dioxide and short glass fiber as reinforcing fillers via mixing, extrusion and calendering-molding process. The physical and chemical properties and fire resistant performance are investigated according to the standard of fire resistant coating for steel structure. The results show that the fire resistance rating can be up to 107 min(2. 0 mm) and 127 min(3.0 mm), moreover, the coated steel structure exhibit excellent physical and chemical properties and is characterized by safe production, eco-compliance, good decorative effect and easy-to-use.
