Surface modification by nano-intercalation amino resin improves the anti-corrosion property of the fire proof coating. The montmorillonite/amino resin nano-meter composite is made by the method of in-situ intercalation, and its dispersion morphology is analyzed by XRD, SEM and TEM. The experiments prove that the nano-intercalation amino resin modified fire proof coating performes well in fire proof and anti-corrosion
