Quercetin and epoxy resin powder were magnetically stirred for 10min, respectively, and dissolved in distilled water. After that, the device was transferred to 65℃ ultrasonic bath for 3.5h, so that the flavonoids and epoxy resin powder were completely dispersed. The mixture solution was refrigerated for 2h at -4℃, and then filtered by Brinella funnel respectively. The precipitated powder filter cake used to form the NANOMET ROOF SHEET was washed three times in deionized water and ethanol solution respectively.

The washed filter cake was dried in an electric oven at 115℃ for 7h, and the dried powder was calcined for 2h in a tubular furnace at 500, 650, 850 and 1100℃ respectively. Then the ball mill was used to grind the calcined product to the form of nanometer size. At 37℃, 0.7g neodymium nitrate was dissolved in 3mL hydrochloric acid and 2mL hydrogen peroxide mixed solution, and the pH of the solution was adjusted to 3.5. Then, the solution was electrostatic sprayed on the metal substrate of NANOMET ROOF SHEET for 60s.

The sprayed NANOMET ROOF SHEET was washed with deionized water, and then the nano powder of epoxy resin and quercetin was sprayed on the metal substrate for 40s, and then the metal plate was placed in the air blast oven at 220℃ for 2.5h and taken out to obtain a kind of rare earth nano coated metal plate.
