Using attached drawing, the invention will be further described, but the embodiment in attached drawing does not constitute any limit to the present invention
System, for those of ordinary skill in the art, without creative efforts, can also obtain according to the following drawings
Other attached drawings.
Fig. 1 is the structural schematic diagram of accumulator of the present invention.
Fig. 2 is the production flow diagram of anticorrosion composite coating of the present invention.
Specific implementation mode
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent and the consistent all embodiments of the present invention.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects being described in detail in claims, of the invention.
Metal is under the action of surrounding medium, since corruption can occur for chemical reaction, electrochemical reaction or physical dissolution etc.
Erosion.Corrosion of metal problem spread economic every field, in life, day commonly used home appliance surface can occur corrosion and
The reduction service life equally faces the various problems that metal erosion is brought, the anticorrosion to metal in fields such as traffic, machinery, chemical industry
Technology has become the very important problem of Material Field.
Currently, mainly metal material and corrosive environment are kept apart, and then avoid metal using the method for surface covering
Be corroded.According to the difference of covering material, surface covering is divided into metal covering and nonmetallic covering.It is to work as using anticorrosive paint
One of preceding most widely used, most effective anticorrosion technique.The chief component of coating has film forming matter, solvent, color stuffing
And auxiliary agent.
Polyaniline has many advantages, such as synthesis material at low cost, scratch resistance, anticorrosive, is a kind of commonly used anticorrosive to have
Machine conducting polymer, studies have shown that polyaniline, which is added in epoxy resin, can be obviously improved its mechanical performance and antiseptic property,
However, polyaniline compound anticorrosive paint still has the problems such as indissoluble, anticorrosion ability is poor at present, therefore develop and expand polyaniline
Application in corrosion-resistant field has very important significance.
Application scenarios one：
Fig. 1 shows a kind of accumulator with corrosion resistance that embodiments herein is related to, including battery jar
1, electrolytic cell is provided in the battery jar, upper cover 2 is equipped on the electrolytic cell, and the electrolytic cell is integral type weldering
Binding structure is provided with electrode in the electrolytic cell；
Preferably, 1 outer surface of the battery jar is equipped with corrosion-resistant coating 3, and 3 thickness of the corrosion-resistant coating is 400~600 μ
M, the corrosion-resistant coating 3 are that anticorrosion composite coating cures 15h shapes coated in 1 outer surface of the battery jar after drying
At.
Corrosion-resistant coating is arranged in the outer surface of battery jar in the present invention, which has suitable thickness, have
Preferable anticorrosion ability, can with effective protection accumulator not in by environment gas, liquid etc. corrosion, to extend accumulator
Service life.
Preferably, using epoxy resin as film forming matter, polyaniline/Al nano-particles are used as and fill out the anticorrosion composite coating
The composite fibre of material, copper carbon fiber and polyaniline fiber composition is as network layer.
In the anticorrosion composite coating of the application, using the composite fibre that copper carbon fiber and polyaniline fiber form as net
Network layers, on the one hand, copper carbon fiber has excellent flexibility and electric conductivity, is conducive to the transmission of conductive ion；Coppered carbon simultaneously
Fiber is used in mixed way with polyaniline fiber, and the two interacts to form network structure so that the application composite coating is in mechanical performance side
Face enhances suppleness, the impact resistance of coating, while the composite network structure enhances the wear-resisting of composite coating composite coating
Property, increase service life；In terms of electrochemistry, corynebacterium copper carbon fiber mutually splices, and forms conductive network, for corrosion electricity
Conductive ion has electric screening action in solution solution, enhances the corrosion resistance of coating；On the other hand, the application anticorrosion is compound
In coating network layer be effectively isolated matrix and corrode electrolyte contact, have physical shielding effect, obstruction corrosive ion to
The diffusion of matrix improves matrix corrosion resistance.
Preferably, the anticorrosion composite coating is using normal propyl alcohol as antifreeze.
In the application anticorrosion composite coating, normal propyl alcohol is added as antifreeze so that at low temperature, the anticorrosion is compound
Paint film still has comparable corrosion resistance, meanwhile, frost resistance and composite fibre synergistic effect, anticorrosion is compound at low temperature
The mechanical performance decline of paint film is relatively low, produces good effect.
It is further preferred that by Fig. 2, the preparation process of the anticorrosion composite coating is as follows：
Step 1 prepares copper carbon fiber：
Carbon fiber is taken, a diameter of 20~50 μm, carbon fiber plates one layer of copper as electrode, using electrochemical method on its surface
Film, copper film thickness are 5 μm, are then cut to 2~3mm length；
Step 2 prepares polyaniline fiber：
It is 1 to take volume ratio:Aniline, is dissolved in distilled water by 60 aniline and distilled water under the action of inorganic acid, surpasses
It under sound, is uniformly mixed, forms solution A, it is 1 then to take mass ratio:50 FeCl36H2O and distilled water, by FeCl36H2O
It is dissolved in distilled water, forms solution B, be then uniformly mixed A, B, wherein A, B volume ratio are 2:3, A, B mixed solution are existed
Reaction 10h is stood under the conditions of ice-water bath, obtains bottle green product, and reaction acquired solution filtering is first washed with deionized water into
Property, then with ethyl alcohol to be washed till filtrate colourless, and product is dried to 30h in drying box, obtains polyaniline fiber；

It takes 5 parts of polyanilines/Al nano-particles and 7 parts of composite fibre to be placed in beaker, 60 parts of N-Methyl pyrrolidones, magnetic force is added
30min is stirred, 2h is then sonicated；
Then 10 parts of epoxy resin and 6 parts of n-butanols are put into another beaker, magnetic agitation 1h, solution in two beakers is mixed
It closes, stirs 2h, sequentially add 3 parts of 4 parts of normal propyl alcohol, 1 part of trbasic zinc phosphate, 2 parts of aluminium triphosphate, 1 part of talcum powder and barium sulfate, then stir
2 parts of 50 curing agent of polyamide 6 are added after mixing 1h, the anticorrosion composite coating is obtained after mechanical agitation 2h.
2. accumulator according to claim 1, which is characterized in that the corrosion-resistant coating thickness is 400~600 μm.
