Description
Technical field
The present invention relates to aseptic technic more particularly to a kind of anti-corrosion materials of ocean platform.
Background technology
For corrosion mechanism, coastal engineering ship is primarily present two kinds of works of electrochemical corrosion and seawater corrosion using process
With.
Electrochemical corrosion refers to the medium of metal surface and ionic conduction because the destruction for occurring to generate during electrochemical action.Its
Two processes that are relatively independent and being carried out at the same time can be divided by being mainly characterized by its reaction mechanism mechanism of reaction --- cathode reaction and
Anode reaction.Its boundary layer for being mainly characterized by charging there is one between metal and electrolyte.
Seawater corrosion refers to the corrosion of the equipment and facility used in marine environment.Saliferous highest in seawater, into split pole
It is complicated, is corrosive electrolyte.It can prevent and destroy containing the chlorion of higher concentration and other halide ions in seawater
The passivation of metal makes anodic process be easier to carry out.Under the conditions of the pH value of seawater, seawater corrosion is oxygen depolarization process, cathode
The speed of corrosion reaction in process control.In addition, seawater velocity, marine organisms etc. also often influence seawater corrosion it is important because
Element.
Corrosion in various environment is extremely complex, and to various equipment, all there are different degrees of influences, mainly have following several
A aspect.
1. metal material whole surface or local thickness is caused to be thinned, so as to influence its intensity, rigidity and mechanical-physical
Energy；
2. movement pair surface erosion corrosion aggravates, increase movement pair surface roughness, so as to resistance, influence even
Damage the expectation function of Working mechanism；To there is the movement pair surface of seal request (such as oil cylinder) to will appear sealing performance reduction；
For the position of connection will appear aperture increase or gap broaden phenomena such as；
3. electrical equipment, under the effects that air, seawater leaching, salt fog, electrochemistry, electric conductivity declines, equipment is caused to exist
It is disabled during use, it is impossible to normal operation；
4. the regional area of metal occur from table and in corrosion cracking, lead crack is mutually perpendicular to tensile stress.In master
During dry crack growth, also several branch development, so as to form stress-corrosion cracking；
5. metal material declines fatigue life under corrosive medium and alternate stress collective effect.
Under normal conditions, large ship cuts to delivery construction period at 12 months or so from steel plate.Under entrance together
Before process, the segmentation of application will often shelve longer time, inevitably have various pollutants and be covered on segmentation coating,
Such as steel fragment, spray dust, weld fumes, consumptive material, acid rain and grease.Meanwhile transport, close up during high-temperature soldering and painting
The protective awareness weakness of layer also be easy to cause the destruction of complete coating, and segmentation corrosion is more apparent, sequent surface processing and coating
It is essential to repair.The construction of especially large-scale luxury liner, construction period is longer, the aesthetics of coating and requirement for anticorrosion compared with
It is high.Traditional upper next procedure is such as welded, fitting-out and carrying construction will certainly damage its appearance of coat.Therefore, such as
What avoids intact breakdown of coating of having constructed, and shortens the coating decoration period, is shipyard general concern and in the urgent need to address asks
Topic.
Invention content
It is an object of the present invention in view of the above-mentioned problems, a kind of anti-corrosion material of ocean platform is proposed, in 0.3mol/L
Find that the preserving timber bed of material of ocean platform can effectively inhibit the active corrosion of stainless steel by corrosion test in HCl/water solution, it is bright
It is aobvious to improve its pitting potential, and film layer enhances the protecting effect of matrix with the increase of thicknesses of layers.
To achieve the above object, the technical solution adopted by the present invention is：A kind of anti-corrosion material of ocean platform, is waited with 12
Sodium alkyl sulfate (SDS) is as surfactant formulatory pyrroles's aqueous solution, and the method for constant current is in 1Crl8Ni9Ti stainless steel watches
Face polymeric conductive polypyrrole film layer.
Further, monomer 3,4-ethylenedioxy thiophene.
Further, solution electrolyte is Lithium perchlorate anhydrous.
Further, surfactant sodium dodecyl base sodium sulfonate, two kinds of solution systems need to be added in when preparing monomer solution
Solvent is respectively acetonitrile and distilled water.
The anti-corrosion material of kind of ocean platform of the invention, has the following advantages compared with prior art：
1) select Stripable paint construction after, will avoid to a certain extent segmentation shelve, transport and welding process in
Destruction to base coat.Pollutant, the weldering cigarette and spatter etc. generated by a variety of causes will be only left on stripping coating,
It will not penetrate on ground coating, protectiveness is good, and resistance to soiling is excellent.
2) Stripable paint construction technology research and application can effectively shorten worker's later stage coating surface treatment and repair
Between added time, certain application period is striven for for nervous painting operation, has reduced security risk.If Stripable paint is constructed
In cabin roof and deck area, subsequently splitting time and repairing.It can be seen that although Stripable paint initial stage input cost
It is higher, but coating efficiency estimation will promote 40% after cabin construction Stripable paint.
3) construction of Stripable paint will promote many position coating process of full ship to be improved, that is, simplify coating construction
Or repairing road number.In the case where execution conditions allow, the possibility of individual sites segmentation application completion increases.
Specific embodiment
The present invention is further described with reference to embodiments：
Embodiment 1
Present embodiment discloses a kind of anti-corrosion materials of ocean platform, wait using lauryl sodium sulfate (SDS) as surface
Activating agent prepares pyrroles's aqueous solution, and the method for constant current is in 1Crl8Ni9Ti stainless steel surface polymeric conductive polypyrrole film layers.It is single
Body is 3,4-ethylenedioxy thiophene.Solution electrolyte is Lithium perchlorate anhydrous.Surface-active need to be added in when preparing monomer solution
Agent dodecyl sodium sulfate, two kinds of solution system solvents are respectively acetonitrile and distilled water.
It is tried out by the real ship of Stripable paint, and combines live practice of construction, it is found that it has the following advantages that：Color is easy
