(2) adding a surfactant into deionized water, uniformly mixing, adding the purified organic bentonite obtained in the step 1, and performing ultrasonic dispersion for 15-20min to obtain a surface activated organic bentonite solution for later use; the surface activation is carried out on the diatomite, so that the surface activity of the diatomite can be greatly improved, and the combination efficiency of the diatomite and other substances is improved;

A large number of oxygen-containing functional groups such as hydroxyl, epoxy, carboxyl, carbonyl and the like are bonded on the surface of the graphene oxide in a covalent bond mode, so that the interplanar spacing of an atomic layer is larger, and the graphene oxide is suitable for organobentonite insertion.

The graphene can be chemically bonded with the surface of the substrate so as to form a corrosion-resistant protective film on the surface of the substrate. However, the protective film of pure graphene has gaps and is not dense, the anticorrosion protection effect of the protective film is limited, and the carbon structure in the graphene and the organic bentonite with the activated surface are well adsorbed and stacked on the metal surface through the synergistic effect of the organic bentonite with the activated surface intercalated on the graphene, so that the dense organic-inorganic hybrid anticorrosion protective film with good flexibility is formed.
