Embodiment 1
[0038] Prepare material A and material B respectively in parts by mass.
[0039] 1) Material A:
[0040]
[0041] 2) Material B
[0042] Monolayer graphene oxide 0.1 parts
[0043] 1 part polyvinyl alcohol
[0044] 30 parts of water
[0045] 3) Mix material A and material B evenly to make the graphene-based coating agent of the present invention.
[0046] Dilute the graphene-based coating agent 20 times with water for use.
[0047] Clean the surface of the aluminum alloy with an acidic or neutral cleaning solution to remove oil and dust on the surface of the aluminum alloy; then clean other impurities remaining on the surface of the aluminum alloy with water; directly soak the aluminum alloy in the diluent of the graphene-based coating agent, The temperature is room temperature, the drying time is about 2 minutes, and it is dried at 80-120°C, or it can be dried at room temperature.
