Background technique
With the development of the city, one of the face of road construction as city also develops therewith, road guard-rail therein
Development also should not be underestimated.In the construction and maintenance of previous protective fence, the main problem encountered is the anti-corrosion of protective fence
Problem, and people solve the problems, such as be mostly make an issue of on the coating of protective guard surface, such as improve starvation ability or
Person can be improved thickness of coating etc., these are able to solve the perishable problem of protective fence to a certain extent, these are all
Anticorrosion is solved by a round-about way, such indirect corrosion-resistant measure can not reach self-cleaning effect.
However, hydrophobic material to be applied to the surface of protective fence, this is always for proposing that the measure of active goes to solve etching problem
The key point that people ignore, hydrophobic material can accomplish self-cleaning effect, at the same time, can also initiatively inhibit protective fence
The corrosion of substrate and the oxidation for slowing down surface answer such technology under the overall background of science and technology rapid development
Of protective fence itself is used, is always that this field cannot be broken through.
Summary of the invention
Technical problem to be solved by the present invention lies in prior art defect is overcome, hydrone can be effectively prevent by providing one kind
The superficial residence of protective fence, the surface for reducing a possibility that corroding are covered with the protective fence and production method of hydrophobic layer.
In order to solve the above technical problem, the present invention provides surface be covered with the protective fence of hydrophobic layer, the protective fence table
Face is followed successively by inorganic zinc layers of chrome, the first hydrophobic layer, the second hydrophobic layer from internal layer to outer layer；First hydrophobic layer is tetradecanoic acid
Hydrophobic layer, second hydrophobic layer are graphene hydrophobic layer.
In the present invention, the tetradecanoic acid molar concentration in the tetradecanoic acid hydrophobic layer is 0.2mol/L, ethyl alcohol mole is dense
Degree is 0.2mol/L, hydrochloric acid molar concentration is 5mol/L.
In the present invention, the inorganic zinc layers of chrome is zinc chrome liquid, and the zinc chrome liquid is by the chromate of 25wt%, the zinc metal sheet of 35wt%
It is formed with 40wt% aluminium flake.
The present invention also provides the preparation methods that above-mentioned surface is covered with the protective fence of hydrophobic layer, comprising the following steps:
1) ungrease treatment, is carried out to protective fence；
2) Shot Blasting, is carried out to protective guard surface；
3), the protective fence after Shot Blasting is immersed in zinc chrome liquid, then dry, solidify and forms inorganic zinc after cooling down
Layers of chrome；
4) tetradecanoic acid, hydrochloric acid, ethyl alcohol, is taken to be configured to mixed solution, the tetradecanoic acid molar concentration is 0.2mol/L,
Ethyl alcohol molar concentration is 0.2mol/L, and hydrochloric acid molar concentration is 5 mol/L；Step 3) treated protective fence submergence mixing is molten
60h-80h in liquid forms the first hydrophobic layer in protective guard surface；
5) technique, is electrostatically sprayed through step 4) treated protective guard surface spraying graphite alkene powder, forms second
Hydrophobic layer.
The beneficial effect of the present invention compared to the prior art is: (1) zinc coat, by zinc chrome liquid formed, Ke Yi great
It is big to improve protective fence corrosion resistance, and zinc chrome liquid has very high permeability and adhesion, guarantees the stability of coating；Ten
Four alkanoic acid hydrophobic layers can form the first hydrophobic protective to protective fence, form uniform first layer on surface by the method for dip-coating；
The second hydrophobic layer of graphene later further protects, and can accelerate protective guard surface water using the super hydrophobic performance of graphene
The exclusion divided shortens hydrone in the residence time of protective guard surface, thus a possibility that reducing corrosion；It is dredged by tetradecanoic acid
The interior fit on of water layer and graphene hydrophobic layer prevents hydrone from entering coating, to effectively protect while accelerating draining
Zinc coat has been protected, has been greatly improved using protective fence corrosion resistance；Meanwhile hydrophobic layer can also to protect to a certain extent
Column surface keeps cleaning；(2), present invention process is simple, easy to make, it is easy to accomplish.
