The invention belongs to the technical field of coating preparation, there is provided a kind of high dispersive, the graphene coating of high corrosion resistant and system
Preparation Method.
Background technology
Graphene (Graphene) is a kind of two dimension (2D) material of novel single-layer laminated structure being made up of carbon atom, is
The hexangle type being made up of carbon atom with sp2 hybridized orbits is in the flat film of honeycomb lattice.Most attracted attention as 21 century by people
One of new material, graphene crystalline material have " to it is thin, to hard ", the characteristic such as excellent heat conductor and electron mobility.
Unique design feature makes its purposes cause the high expectation of people plus " extreme prominent " performance, and graphene is or will
Revolutionary great change is brought to society, research temperature is persistently overheating in the whole world!To graphene conduction, anti-corrosion, fire-retardant, heat conduction and
Colorful prospect has also been delineated in application in the functional paints such as high intensity.
Graphene coating is to utilize graphene high-specific surface area, Quick conductive, excellent chemical stability, the power of protrusion
Learn one of important uses of performance such as performance, high-termal conductivity.Graphene is used to that in coating pure graphene coating and graphite can be prepared
Alkene composite coating, the former is primarily referred to as pure graphene and plays the functional paint of the effects such as anticorrosion, conduction in metal surface；The latter
It is compound with fluoropolymer resin first to be primarily referred to as graphene, functional paint is then prepared with composite.Graphene can be carried significantly
The performance of polymer is risen, therefore graphene composite coating turns into the important application research field of graphene.Graphene applies in conduction
The combination property of coating can be greatly improved in the coating systems such as material, anticorrosive paint, anti-flaming dope, such as reduces coating layer thickness,
Increase the adhesive force to base material, lift coating wearability, and make coating that there is green environmental protection.Especially in electrically-conducting paint, epoxy
In zinc-rich paint, water-based anticorrosive paint there is prominent performance to show, graphene will promote the new round industrial transformation of coating
Upgrading.
With the largely functionalization graphene containing oxy radical, it is strong with the adhesion of resin, high polymer material, and its suitable
Cooperation supporting material or functionalization material.The mode majority applied to coating of graphene is using graphene as feature at present
Filler is added, and it is the dispersion stabilization problem for how solving graphene, it is necessary to graphite thus to bring a key issue
Alkene is modified.Liu Lin etc. result of study shows：Chemically modified graphene and the surface of graphene oxide have abundant
Functional group（Hydroxyl, carboxyl, epoxy radicals）, can realize that nanoscale disperses in polymer body, so as to effectively assign and
Improve the performance of polymer.Another application mode of graphene is to be prepared into graphene by the compound method of organic/inorganic
Composite, realize the stable dispersion of graphene and its performance of features.
At present both at home and abroad in graphene coating preparation, especially graphene dispersion, rotproofness and resistance to acids and bases etc.
Research achieved certain effect.Wherein wear a kind of graphene anticorrosive paint of the emerging invention of benevolence（Chinese invention patent application number
201610878263.1）, increase the stability of graphene by carrying out secondary oxidation modification to graphite, be advantageous to maximum performance
The decay resistance of graphene in itself, the coating for making to prepare have excellent adhesive force, hardness and wearability and resistance to neutral salt
Mist corrosivity, but this method material requested is more, and preparation process is complicated, and cost is higher, and dispersiveness and resistance to acids and bases are bad.Separately
Outside, Qu Yanfa understands a kind of bi-component graphene anticorrosive paint（201510497999.X）, graphene is added to anti-by this invention
In rotten coating, the thickness of coating paint film is greatly reduced；By the selection to each component, while antiseptic effect is improved, greatly
The big content for reducing zinc powder, overcomes zinc-rich paint to sacrifice anti-corrosion mode of the zinc powder as cost, greatly reduces and welding
Caused zinc oxide fog, environment-friendly, but this method complex technical process, cost is higher, at the same unresolved graphene with
The combination sex chromosome mosaicism of carrier.
It can be seen that cause its scattered uniformity, fine and close sexual intercourse there is the agglomeration because of graphene in itself in the prior art
Fork, easily overlap aggregation, at the same exist when graphene is equipped on general carrier with reference to it is insecure, easy to fall off, load factor is low
The problems such as.
The content of the invention
