Description
Technical field
The present invention relates to a kind of protective system, particularly relate to a kind of application over rust low prepared surface rust-proofing primer peculiar to vessel.
Background technology
In ocean environment, in use unavoidably there is various corrosion failure in offshore engineering equipment, offshore oil gas platforms and boats and ships, has a strong impact on its safety and work-ing life.Corrode mainly material corrosion factor (water, oxygen, ion, microorganism etc.), and react with it, make the form of material, process that structure changes.In order to slow down ferrous materials corrosion process, extend the work-ing life of product, ensure use safety during one's term of military service, people have used various anti-corrosion method, as developed various corrosion-resistant steel; Surface heat zinc-plate process is utilized to protect iron and steel; Cathode protection method is utilized to protect component in corrosive medium; Utilize surface-coated protective system method to steel construction protection etc., comprehensive prior art and cost factor are considered, adopt paint spraying protection to be extensive, effective and the most economic method.In order to obtain good effect, go to toward needing to carry out the surface treatments such as polishing cleaning to ground in application.According to the study, surface-treated quality is comparatively large to painting film lifetime effects, about has half coating failure to be caused by surface treatment.Common heavy-duty coating is when application in order to reach high performance protection effect, and hull and steel piece surface must take the process means such as sandblasting to remove iron rust, to strengthen the bonding force of coating and steel surface.But this method not only can increase cost, the dust in sandblasting procedures and noise also can serious harm workmen healthy, the scope of operation for some complex construction is difficult to accomplish to remove completely clean.In order to solve the problem, the low surface treatment paint (Surface Tolerant Coating) that can meet application over rust becomes domestic and international association area study hotspot.
In order to realize application over rust; in paint manufacturing process, normally add permeate agent, polar solvent and active protection material makes residual rust stablize passivation or conversion; active corrosion product is converted into and stablizes harmless material, thus realize the object increasing protected effect and the loaded down with trivial details treatment process of reduction.Although above-mentioned on rust paint is widely applied, but still exist a lot of not enough, as application over rust coating in use how much affect by steel structure surface corrosion Product bulk amount, a lot of coating turns rust and surely become rusty object as active substance to play using chromic salts or phosphoric acid salt, easily cause heavy metal contamination and eutrophication, effect is still not enough to satisfactory.
New thinking and direction are opened up in the development being introduced as coatings industry of nanotechnology in recent years, utilize the doping of nano particle, realize composite modified in small scale of organic/inorganic component, thus rigidity outstanding to film-forming properties excellent for organic polymer, ductibility, workability and inorganic materials, stability are combined, greatly improve the performance of coating.Result of study shows, by nano-ZnO, CaCO
3, TiO
2take suitable ratio to add in preparation process in coating Deng nano particle as filler, effectively can improve the performance of coating.The particularly doping of nano ZnO particles, can protect metallic matrix effectively, greatly slows down its corrosion process, increases the service life.
Carry out based on nano zine oxide and uhligite composite modified after nano combined antirust color stuffing system, under organic additive modification, the multiple microlayer structures of orderly formation of deposits, effectively can stop the infiltration of corrosive medium, play good shielding effect, realize good preservative effect.Meanwhile, through the modified nano combined antirust color stuffing system of organic composite and epoxy resin latex affinity good, be easy to dispersion, the rust proof paint of preparation can steady in a long-termly be preserved.
The active iron rust passivation that obtained nano combined rust-proofing primer can be contacted on the one hand, suppresses the further generation of corrosion; On the other hand the sorption of paint film is by iron rust from surperficial pull-up, and by being wrapped up through the crystal grain transformed in priming paint, starvation and moisture, prevent further corrosion.The toughness of organic resin, cohesiveness are fully combined with the rigidity of inorganic powder by this protective system, and the film of formation has the advantage that sticking power is large, anti-corrosion, film shrinking percentage is low, good penetrability, hardness are large.
