Technical field
The application relates to electric power cabinet field, particularly relates to a kind of corrosion-resistant jamming-proof electric power cabinet.
Background technology
At power domain, electric power cabinet is a kind of common equipment, and for current electric power cabinet, it is mainly by the metal of cuboid
Shell is constituted.In the work of electric power cabinet, due to complex environment, such as electromagnetic interference problem, humidity, corrosion problems etc.,
The normal use of electric power cabinet can be caused the biggest interference or impact.
Existing anticorrosion technique usually uses cladding process, coats one layer of anticorrosive coating at target object surface, still
Face the problems such as anticorrosive coating protection effect is the best.
Summary of the invention
It is desirable to provide a kind of corrosion-resistant jamming-proof electric power cabinet, to solve problem set forth above.
Embodiments of the invention provide a kind of corrosion-resistant jamming-proof electric power cabinet, including cabinet, it is characterised in that institute
State and on cabinet outer wall, be coated with tinned copper wire woven shield, described tinned copper wire woven shield outer wall is enclosed with high temperature resistant
Layer, high-temperature-resistant layer outer wall is coated with corrosion-resistant coating；It is provided with power module in described cabinet, is provided with power supply on the upside of power module and prevents
Thunder device.
The technical scheme that embodiments of the invention provide can include following beneficial effect:
The present invention is coated with screen layer, screen layer and electric power cabinet inwall at electric power cabinet outer wall and is equipped with corrosion-resistant coating, and it can
Effectively to prevent the corrosion to electric power cabinet such as gas, liquid in environment, or corrosiveness is reduced, thus solve above-mentioned
Proposition problem.
Aspect and advantage that the application adds will part be given in the following description, and part will become from the following description
Obtain substantially, or recognized by the practice of the application.It should be appreciated that above general description and details hereinafter only describe
It is exemplary and explanatory, the application can not be limited.
Accompanying drawing explanation
The invention will be further described to utilize accompanying drawing, but the embodiment in accompanying drawing does not constitute any limit to the present invention
System, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain according to the following drawings
Other accompanying drawing.
Fig. 1 is the structural representation of electric power cabinet of the present invention.
Fig. 2 is the Making programme figure of composite coating of the present invention.
Detailed description of the invention
Here will illustrate exemplary embodiment in detail, its example represents in the accompanying drawings.Explained below relates to
During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represents same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the present invention.On the contrary, they are only with the most appended
The example of the apparatus and method that some aspects that described in detail in claims, the present invention are consistent.
Metal, under the effect of surrounding medium, can occur corruption due to chemical reaction, electrochemical reaction or physical dissolution etc.
Erosion.Corrosion of metal problem is throughout economic every field, in life, the daily home appliance surface used can occur corrosion and
Reduce the life-span, in fields such as traffic, machinery, chemical industry, face the various problems that metal erosion brings equally, the anticorrosion to metal
Technology has become as the problem that Material Field is very important.
At present, the main method using surface to cover, metal material is kept apart with corrosive environment, and then avoids metal
Be corroded.According to the difference of covering material, surface covers and is divided into metal to cover and nonmetal covering.Using anticorrosive paint is to work as
One of front most widely used anticorrosion technique general, maximally effective.The key component of coating has film forming matter, solvent, color stuffing
And auxiliary agent.
Polyaniline has synthesis material low cost, scratch resistance, the advantage such as anticorrosive, is a kind of commonly used anticorrosive to have
Machine conducting polymer, research shows, polyaniline joins and can be obviously improved its mechanical performance and antiseptic property in epoxy resin,
But, current polyaniline compound anticorrosive paint still has the problem such as indissoluble, anticorrosion ability difference, therefore develops and expands polyaniline
Application in corrosion-resistant field has very important significance.
Application scenarios one:
Fig. 1 shows the corrosion-resistant jamming-proof electric power cabinet of one that embodiments herein relates to, including cabinet 1, described
It is coated with tinned copper wire woven shield 3 on cabinet 1 outer wall, described tinned copper wire woven shield 3 outer wall is enclosed with resistance to height
Temperature layer 4, described high-temperature-resistant layer 4 is refractory cement, described high-temperature-resistant layer 4 outer wall is coated with corrosion-resistant coating 2, in described cabinet 1
Wall is coated with corrosion-resistant coating 2；It is additionally provided with power module in described cabinet 1, on the upside of power module, is provided with lightning protection for power supply.
Preferably, described corrosion-resistant coating 2 thickness is 200～400 μm, described corrosion-resistant coating 2 applied by composite coating after warp
Crossing dry, solidification 20h is formed.
Embodiments of the invention are by being provided with corrosion-resistant coating at the screen layer of described electric power cabinet and inwall, and it can be the most anti-
The only electromagnetic environment interference to electric elements inside, security performance is high, and can effectively prevent gas, liquid etc. in environment right
The corrosion of electric power cabinet, or corrosiveness is reduced.
Preferably, described composite coating is with epoxy resin as film forming matter, and polyaniline/Al nanoparticle is as filler, plating
The composite fibre of copper carbon fiber and polyaniline fiber composition is as Internet.
In the composite coating of the application, the composite fibre formed using copper carbon fiber and polyaniline fiber as Internet,
On the one hand, copper carbon fiber has the transmission of excellent pliability and electric conductivity, beneficially conductive ion；Simultaneously copper carbon fiber with
Polyaniline fiber is used in mixed way, and both form network structure alternately so that the application composite coating, in mechanical properties, strengthens
The suppleness of coating, impact resistance, this composite network structure enhances the wearability of composite coating simultaneously, increases and uses the longevity
Life；In terms of electrochemistry, corynebacterium copper carbon fiber mutually splices, and forms conductive network, for conducting electricity in corrosion electrolytic solution
Ion possesses electric screening action, strengthens the corrosion resistance of coating；On the other hand, in the application composite coating Internet effectively every
From matrix and contacting of corroding electrolyte, there is physical shielding effect, hinder the corrosive ion diffusion to matrix, improve matrix
Corrosion resistance.
Preferably, described composite coating is using normal propyl alcohol as antifreeze.
In the application composite coating, add normal propyl alcohol as antifreeze so that at low temperatures, this composite coating thin film still has
There are suitable corrosion resistance, meanwhile, frost resistance and composite fibre synergism, the at low temperatures mechanical performance of composite coating thin film
Decline relatively low, create good effect.
