Description
Technical field
The present invention relates to hydrophobic material preparation technical fields, and in particular to a kind of modified bottom surface of high-temperature and high-presure resistent graphene
Unify anticorrosive paint and preparation method thereof.
Background technique
In world wide, as oil field development enters the middle and later periods, injection well pipe column damage problem is got worse, and becomes puzzlement
The a great problem of petroleum industry later period exploitation.Oil and gas enterprise to can be improved oil pipe service life, increase oil gas well development peace
The water injection pipe surface modification technologies of full property propose strong production requirement.However, the surface treatment skill of traditional waterflood pipe
There are following limitations for art: what its ontology of Epoxy Resin/Phenol aldehyde epoxy coating was difficult to avoid that contains the intrinsic defects such as pin hole, in high temperature and pressure
Coating cannot prevent Cl under environment-、H2O and O2Etc. small molecules infiltration, and it is easily old higher than 90 DEG C of environment floating coat in temperature
Change；For corrosion resistant alloy coating, under the premise of guaranteeing anti-corrosion effect, the thickness and consistency requirements to coating are high, accordingly
Need to add the precious metal elements such as more Ni, W, cause its increased costs, and plating process controlling need to be improved；This
Outside, there is durability in the nonmetallic oil pipe of nitriding carbon steel oil pipe, passivation of metal surfaces, high-strength high-density, non-metallic inner liner oil pipe
The problems such as poor.Wherein failure caused by environmental corrosion is the main reason of injection well pipe column damage, ends 2013 according to statistics
Domestic injection well pipe column exists there are about 10,000 mouthfuls or more corrodes caused Problem of Failure, and oil field causes tremendous economic to damage because of corrosion
It loses, especially corrosion failure accident, seriously affects the normal production in oil field.
The wear-resisting erosive wear resistance of its ontology of traditional organic coating is poor, and coating cannot prevent Cl under hot environment-、H2O and
O2Etc. small molecules infiltration, it is easy to aging higher than 90 DEG C of environment floating coat in temperature.Equipment for applying in special dimension,
Need coating that there is stronger high-voltage performance resistant to high temperatures, impervious antiseptic property.Therefore, the anti-corrosion coated layer haveing excellent performance is in market
It is middle by urgent demand extensively.
Summary of the invention
The invention aims to overcome current technology and technologic deficiency, the high temperature resistant for providing a kind of bottom surface unification is high
Press graphene anticorrosive paint.
A kind of modified primer-topcoat integrated anticorrosive coating of high-temperature and high-presure resistent graphene, including component A and B component；
By percentage to the quality, component A consists of the following compositions:
The sum of each ingredient percent of component A is 100%；
B component accounts for the 8~12% of component A gross mass；
B component is epoxy hardener.
Wherein, graphene occupies the 0.2~7% of solvent gross mass.
Wherein, graphene accounts for the 0.25~5% of epoxy resin gross mass.
Wherein, the epoxy resin is that novolac epoxy resin (DEN431), bisphenol A epoxide resin (E20) or organosilicon change
At least one of property epoxy resin.
Wherein, the organic solvent is by dimethylbenzene, n-butanol, cyclohexanone, Isosorbide-5-Nitrae butanediol diglycidyl ether composition.
Wherein, the pigment is one of carbon black or titanium dioxide.
Wherein, the filler is mica, silica flour, silicon carbide, talcum powder, blanc fixe, trbasic zinc phosphate, ferrophosphorus powder, prevents
At least one of heavy wax powder, micaceous iron oxide.
Wherein, the auxiliary agent be Ricinate, silane coupling agent, adhesive force auxiliary agent, defoaming agent, in levelling agent at least
It is a kind of.
Wherein, the epoxy hardener is the mixture of modified alicyclic ring amine hardener and aromatic amine curing agent, wherein modified
Alicyclic ring amine hardener and aromatic amine curing agent compare=1:1 according to parts by weight.
In addition, the present invention also resides in the preparation for disclosing a kind of modified primer-topcoat integrated anticorrosive coating of high-temperature and high-presure resistent graphene
Method, the preparation method mainly include the following steps:
S1: graphene is added in configured organic solvent, is configured to graphene dispersion by being ultrasonically treated 60min
Liquid；
S2: it by novolac epoxy resin DEN431, bisphenol A epoxide resin E20, is added into graphene dispersing solution, sufficiently stirs
It mixes until all resin dissolutions completely, form slurry；
S3: pigment, filler being added in the slurry, and auxiliary agent is added, and the revolving speed for being kept stirring machine is 1500r/min, stirring
1h forms paint vehicle；

25 coating basic performance list of embodiment 21- embodiment
According to Experimental results show, the addition of graphene generates beneficial effect to corrosion-inhibiting coating.In a certain range, with
The increase of graphene content, coating high temperature high voltage resistant performance significantly improve.This is because, the nanoscale twins knot that graphene is special
Structure can be filled in the hole and defect of coating, fine and close physical isolation layer be formed, to reach the anticorrosion to metal material
Function.With resin scion grafting, increase the stability of chemical bond, improves the intensity and impermeability of coating.Good heating conduction makes it
It is played an important role in high temperature high voltage resistant anticorrosive paint.The increase of graphene content plays its effect more obvious, resistance to
Warm nature can be promoted.However, not having beneficial effect instead when graphene content reaches 1.0%~1.2%.This be by
There is strong interactions between graphene sheet layer, if the graphene of big component is directly added to resin material
In, agglomeration easily occurs for graphene, will will appear more micropores at this time, can make to reduce anti-corrosion effect instead.Therefore, stone
The additive amount of black alkene and dispersion are the critical issues that can graphene effectively be applied in anticorrosive paint.In test process
In, the ratio and solvent ratios of epoxy resin are changed, and add novel substance polysulfide rubber.The ratio of epoxy resin
The flexibility and adhesion performance for being added to improve coating of example variation and polysulfide rubber, are an optimization process, but
It can satisfy the requirement of national standard.The variation of solvent ratios is to be able to better dispersed graphite alkene, it was proved that stone
Black alkene is able to carry out preferable dispersion in the range of appropriateness, gives full play to the performance of graphene, improves to coating performance.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
