Aqueous anticorrosive coating and preparation method thereof

[0036] As a kind of water-based anticorrosion coating of the embodiment of the present invention, described coating comprises the component of following parts by weight:

[0037] 100 parts of epoxy acrylate, 1 part of metal oxide nanomaterial supported by graphene oxide, 5 parts of curing agent, the preparation method of the curing agent comprises the following steps: (1) under inert gas atmosphere, normal tetrabutyl titanic acid Esters and ethylene glycol were mixed and stirred at 68-72°C for 20-40 minutes; (2) triethanolamine was added to the system of step (1), and stirred and reacted at 82-87°C for 2.5-3.5 hours; the n-tetrabutyl The molar ratio of titanate, ethylene glycol and triethanolamine is 1:0.8-1.2:1.8-2.2;

[0038] The epoxy acrylate is synthesized by epoxy heptanoate and acrylic polymer, and the weight ratio of the epoxy heptanoate and the acrylic polymer is: 6:100; the monomer of the synthetic acrylic polymer includes methyl Acrylic acid, ethyl methacrylate and...

[0051] As a kind of water-based anticorrosion coating of the embodiment of the present invention, the only difference between this embodiment and embodiment 1 is: the monomer of the synthetic acrylic polymer includes methacrylic acid, ethyl methacrylate and octyl methacrylate, The parts by weight of the synthetic acrylic acid polymer monomer are: 8 parts by weight of methacrylic acid, 20 parts by weight of ethyl methacrylate and 80 parts by weight of octyl methacrylate.

[0053] As a kind of water-based anticorrosion coating of the embodiment of the present invention, the only difference between this embodiment and embodiment 1 is: the monomer of the synthetic acrylic polymer includes methacrylic acid, ethyl methacrylate and octyl methacrylate, The parts by weight of the synthetic acrylic acid polymer monomer are: 12 parts by weight of methacrylic acid, 20 parts by weight of ethyl methacrylate and 80 parts by weight of octyl methacrylate.
