Abstract
The invention discloses a method for preparing an ocean anticorrosion coating.The method comprises a step a) of performing oxidation treatment on a base material; a step b) of treating the basic material through an aminosilane coupling agent to form a coupling agent film layer, wherein the aminosilane coupling agent is one or the mixture of more selected from a group comprising gamma-aminopropyl methyl diethoxysilane, gamma-aminopropyl methyldimethoxysilane, gamma-aminopropyl trimethoxysilane, gamma-aminopropyl triethoxysilane, N-beta-(aminoethyl)-gamma-aminopropyl trimethoxysilane and diethylenetriamine propyl methyldimethoxysilane; and a step 3) of spraying graphene oxide on the basic material to form the film layer, and drying the film layer.By adoption of the method, adhesive force between the coating and the basic material is improved obviously, and thus the service life of the coating is prolonged indirectly.
Description
Technical field
The present invention relates to marine anticorrosion coatings art, specifically, the preparation method relating to a kind of marine anticorrosion coating.
Background technology
Ocean covers the earth 4/5 area, and China has more than 300 ten thousand square kilometres of marine sites.Exploitation marine resources can alleviate the present situation of current resource scarcity effectively.But sea water is that in nature, quantity is maximum and have corrosive natural electrolytes, the facility in ocean can be caused serious infringement.Therefore, while exploitation marine resources, marine corrosion and protection one of major fields becoming global concern.
Coating, because simple and convenient feature, is always up the most widely used method in marine anticorrosion erosion field.At present, marine anticorrosion application is maximum or composite anti-corrosive coating, and this coating is to be subsequently formed through the dry solidification of coating.Such as, CN103990588A long-lasting protection anticorrosion coat disclosing a kind of ocean steel construction and preparation method thereof, it is mainly made up of polycarboxy epoxy coating, non-solvent epoxy coating, acrylic acid epoxy finish paint or polyurethane epoxy finish paint or organosilicon epoxy finish paint or fluorine carbon finishing paint；CN202123747U has then invented the alloy resin composite anti-corrosive coating of steel construction under a kind of marine environment, it include Zn coating, Al coating, nano paint coating, four layers of polyurethane finish coating；CN200979035Y relates to the steel pipe of a kind of modified chlorinated rubber outer anticorrosive coating with marine anticorrosion erosion；CN101987937A provides in splash zone ocean steel construction super thick film corrosion-inhibiting coating, is made up of priming paint, finish paint and cover finish paint.
But coating is because having, and toxicity is big, storage takes up room, rete controls the features such as difficult.Therefore, directly anticorrosion and antifouling protecting film is formed or necessary at substrate surface by the method for chemical graft or self assembly.Directly can thus prepare the base material with corrosion-inhibiting coating.At present, the preparation method that CN102559011A has invented a kind of epoxy anticorrosive coating, but be also first obtain solid additive to be added to again in coating and eventually form coating.So, but without utilizing the chemical graft preparation method to prepare marine anticorrosion coating.
Nano material, because its good conduction, heat conduction, mechanical property, big specific surface area, since being found, has quickly been applied at the corrosion-resistant field of coating.Such as, CN104140744A discloses a kind of nanometer anticorrosive coating suitable in marine environment；CN104559669A relate to a kind of Graphene organic anti-corrosive erosion coating being applied to marine ship；The preparation method of a CN104231703A Graphene composite anti-corrosive coating；The preparation method that CN105111925A discloses a kind of titanium dioxide-polyaniline composite anti-corrosive coating, is applied to nano titanium oxide in anticorrosion with coat.
The present invention is directed to the problems referred to above, be prepared for a kind of marine anticorrosion coating by chemical method, in view of the superperformance of nano material, then graphene oxide be used for the preparation process of coating.This is because its surface of graphene oxide has abundant functional group's (hydroxyl, carboxyl, epoxy radicals), these groups can as the avtive spot of reaction kinetic, not only can with polymer but also its mechanical performance of raising and electrical and thermal conductivity performance can be combined with inorganic matter.Simultaneously taking account of the connectivity problem between graphene oxide and base material, amino silicane coupling agent is applied to this as connecting inorganic matter with organic " bridge ".
