Abstract
The present invention relates to a polyaniline corrosion preventing sealant which belongs to the field of adhesives. The polyaniline corrosion preventing sealant comprises the following components (by weight parts): 2 to 2.5 parts of eigenstate polyaniline, 6 to 7 parts of lanolin, 8 to 12 of vaseline, 20 to 25 parts of lithium base grease, 0.3 to 0.5 part of span-80, 45 to 50 parts of epoxy resin, 6 to 7 parts of barium petroleum sulfonate, 1.5 to 2 parts of zinc naphthenate, 0.5 to 1 part of dibutyl phthalate and 5 to 10 parts of xylene. The polyaniline corrosion preventing sealant has the advantages that polyaniline is used as corrosion preventing stuffing for the first time and is mixed in an adhesive, and the quality requirement of the adhesive for metal corrosion prevention is improved. The polyaniline corrosion preventing sealant has obvious corrosion preventing effect.
Description
Technical field
The invention belongs to adhesive area, in order to improve the Corrosion Protection of product to metal.
Background technology
Various metal bolts, screw thread, fastening piece are under the corrosive environment harsh conditions, and under ocean, acid, caustic corrosion serious condition, corrosion phenomena is very general, and serious causing can't normally be dismantled.Petroleum industry particularly, the thread of oil recovery, gas well bar, pipe, cause the corrosive material owing to contain hydrogenchloride, hydrogen sulfide, carbonic anhydride, oxygen, organic acid, water vapour etc. in the oil and natural gas, cause the screw thread position at first to corrode, influence oil gas well ordinary production.Screw on deepwater production vessel, the boats and ships is very easily corrosion also.The problems referred to above adopt antirust grease to seal solution more.But antirust grease is sea water resistance not, and the chance heat loss is fast in oil, gas well, the preserving and sealing effect of playing that can not be permanently effective.
Summary of the invention
The invention provides a kind of anticorrosive polyaniline seal gum, to solve not sea water resistance of present antirust grease, the chance heat loss is fast in oil, gas well, the problem that plays the preserving and sealing effect that can not be permanently effective.The technical scheme that the present invention takes is: the component that comprises following weight part:
2～2.5 parts of polyaniline in eigenstate, 6～7 parts in lanolin, 8～12 parts in Vaseline, 20～25 parts of lithium soap greases, 0.3～0.5 part of sorbester p17,45～50 parts of Resins, epoxy, 6～7 parts of barium mahogany sulfonates, 1.5～2 parts of zinc naphthenates, 0.5～1 part of dibutyl phthalate, 5～10 parts of dimethylbenzene.
The component that can also add following weight part:
Solidifying agent: 18～24 parts of epoxy curing agents.
A preferred mode of the present invention is:
2.5 parts of polyaniline in eigenstate, 6.9 parts in lanolin, 10 parts in Vaseline, 21 parts of lithium soap greases, 0.3 part of sorbester p17,45 parts of Resins, epoxy E51,6.9 parts of barium mahogany sulfonates, 1.8 parts of zinc naphthenates, 0.6 part of dibutyl phthalate, 5 parts of dimethylbenzene.
Another preferred mode of the present invention is:
The component that can also add following weight part:
Solidifying agent: 20 parts of Ka Delai NX-2015.
The invention has the advantages that first polyaniline to be mixed in the tackiness agent, improve the quality requirements of tackiness agent anti-corrosion of metal as anticorrosive packing.Preservative effect of the present invention is very remarkable, and its anticorrosion mechanism is different with traditional anticorrosive adhesive stick.Be to contact with metal base and interact by the material that contains polyaniline to reach corrosion-resisting function, its mechanism is as follows: polyaniline contacts with metal base, the electrochemical corrosion potential of metal base is shuffled, it is easy corrosive metal, as steel, cast iron, aluminium, copper etc., move to positive potential by original negative corrosion normotopia, reach or near the electropotential of precious metal such as gold and silver etc.Make metal base generation passivation,, form one deck densification, stable zone of oxidation accordingly, as Fe to different metals
