Description
Technical field
The invention discloses a kind of preparation method for suppressing carbon dioxide corrosion coating, belong to technical field of coatings.
Background technology
It is well known that CO2Corrosion is the corrosion type that a kind of extremely strong general corrosion of destructive power is laid equal stress on local corrosion；And
CO2One of component of injection gas or natural gas in being adopted often as associated gas, three is widely present among oil gas.It is this
Corrosion is usually related with scene temperature and pressure factor, and the failure consequence of tubing and casing and feed-line caused by it is very tight
Weight.For example, in May, 1971 Sichuan prestige gets over small stream section due to the CO in desulfurizing and purifying gas into pipeline2And remaining H2The corrosion failure of S draws
Play explosion, burning, 24 people of injures and deaths.1975, Alpha's platform in the Ekofisk oil fields of North Sea oil field Norway side, due to original
It is high in oil to contain CO2And chlorion so that 103/4 inch of APIX50 high temperature standpipes come into operation only two months, just corrode thin
Such as page, set off an explosion, burn and human casualty accident.A bite gas well of the refined carat gas condensate field in China, is being on active service 10 months
Afterwards, due to CO2Corrosion cause oil pipe to perforate blowout, catch fire 76 days, direct economic loss is up to more than 3,000 ten thousand yuan, indirect economy damage
Mistake is several times as much as this number.Further, since CO2Corrosion and caused by oil pipe perforation fall well, sucker rod rupture etc. it is even more commonplace.This
A little pernicious malicious events, not only result in huge economic loss, and can bring serious societal consequence.
Petroleum industry is always to produce the severely afflicated area of etching problem, and wherein particularly prominent with the etching problem of oil field pipeline
Go out.Since oil and natural gas pipeline working condition is complicated and changeable, so environment has difference more, although after oil gas field collection all
The purified treatment such as dehydration, desulfurization can be passed through, but pipeline inner wall generally allows there are different degrees of heavy corrosion.Sour gas H2S
And CO2Can not only significant threat be formed to ground gathering line and equipment safety, go back entail dangers to personal safety and property safety, because
This, it is one of current urgent important business to carry out corrosion control technology.The country is in terms of oil-gas pipeline inner wall corrosion is controlled at present, except adding
Outside being rigid in checking up to oil product and conveying process by force, using it is most be inner wall anti-corrosive coating.Anti-corrosion in countries in the world
In erosion practice, it is most effective, most economical, using most common method to also demonstrate that coating antiseptic.But the existing anti-H of coating2S
It can meet the requirements substantially, but itself defect is larger, and the Percentage bound and permeability resistance of coating and metal body are poor, and
And most of anticorrosive paint is all solvent type, largely using volatile organic compounds, and suppresses CO2Corrosive effect is poor.
The content of the invention
Present invention mainly solves technical problem：For the suppression CO of traditional coating2Corrosive nature is poor, with metal body
The defects of Percentage bound is low and permeability resistance is poor causes the service life of metal pipe material to shorten, there is provided one kind suppresses carbon dioxide
The preparation method of etching ground.First the addition material mixing such as acrylic monomer and initiator is uniform by the present invention, is then added drop-wise to
Carry out reacting obtained epoxy grafted and modified acrylic resin resin in epoxy resin solution, then by itself and dispersant, water-reducing agent, wollastonite
Powder etc. is mixed, is disperseed, being ground and to be obtained slurry, finally by obtained immobilization carbonic anhydrase and polyvinylpyrrolidone, slurry,
Emulsifying agent and defoamer high speed dispersion are inhibited carbon dioxide corrosion coating, the coating water-proof performance that the present invention is prepared
Good, effective to reduce carbon dioxide with water reaction production carbonic acid to corrosion of metal, the addition immobilization carbonic anhydrase in coating can
