The powder of aspicin and epoxy resin were stirred magnetically for 20min, respectively, and dissolved in distilled water. After that, the device was transferred to ultrasonic bath at 70℃ for ultrasonic treatment for 4h, so that the flavonoids and epoxy resin powder were completely dispersed. The mixed solution was refrigerated at -4℃ for 2.5h, and then filtered by Brinberg funnel respectively. The precipitated powder filter cake was formed and coated on the NANOMET ROOF SHEET and washed three times in deionized water and ethanol solution respectively.

The washed filter cake was dried in an electric oven at 130℃ for 5.5h, and the dried powder was calcined for 2h in a tubular furnace at 500, 700, 900 and 1200℃ respectively, and then the ball mill was used to grind the calcined product to the form of nanometer size. At 35℃, 1.5g lanthanum chloride was dissolved into 5mL sulfuric acid and 5mL hydrogen peroxide mixed solution, and the pH of the solution was adjusted to 3.5. Then the solution was electrostatic sprayed onto the metal substrate of NANOMET ROOF SHEET for 60s.

The sprayed NANOMET ROOF SHEET metal plate was washed with deionized water, and then the nano powder of epoxy resin and poplar was sprayed on the metal sample for 55s. After that, the metal plate was placed in a 250℃ blast oven for 3.0h and taken out, a kind of rare earth nano coated metal plate could be obtained.
