A kind of and steel pipe of the modified chlorinated rubber outer anticorrosive coating with marine anticorrosion erosion；CN101987937A provides splash zone sea
Foreign steel construction super thick film corrosion-inhibiting coating, is made up of priming paint, finish paint and cover finish paint.
But coating is because have the characteristics that big toxicity, storage space-consuming, film layer control are difficult.Therefore, directly in base material
Surface forms anticorrosion and antifouling diaphragm or necessary by chemical graft or the method for self assembly.Can directly thus
Prepare the base material with corrosion-inhibiting coating.At present, CN102559011A has invented a kind of preparation method of epoxy anticorrosive coating, but
It is first to obtain solid additive and be added in coating again to eventually form coating.So chemical graft is not utilized also to make
The preparation method of standby marine anticorrosion coating.
Nano material is because its good conduction, heat conduction, mechanical property, big specific surface area, since being found, soon
The corrosion-resistant field in coating of speed is applied.For example, CN104140744A discloses a kind of nanometer suitable for marine environment
Corrosion-inhibiting coating；CN104559669A relate to a kind of graphene organic anti-corrosive applied to marine ship and lose coating；
A kind of preparation methods of graphene composite anti-corrosive coating of CN104231703A；CN105111925A disclose a kind of titanium dioxide-
The preparation method of polyaniline composite anti-corrosive coating, nano titanium oxide is applied in anticorrosion with coat.
The present invention by chemical method in view of the above-mentioned problems, be prepared for a kind of marine anticorrosion coating, in view of nano material
Superperformance, graphene oxide to be then used for the preparation process of coating.Enriched because its surface of graphene oxide has
Functional group's (hydroxyl, carboxyl, epoxy radicals), these groups can be as the avtive spot of reaction kinetic, both can be with polymer
It can be combined again with inorganic matter and improve its mechanical performance and electrical and thermal conductivity performance.Simultaneously in view of between graphene oxide and base material
Connectivity problem, amino silicane coupling agent is applied to this as connection inorganic matter and " bridge " of organic matter.
