Description
Technical field
The present invention relates to paint field, more particularly, to a kind of oil pipeline with aqueous heavy antisepsis epoxy primer.
Background technology
Pipeline transportation is one of big means of transportation in the world five.At present, the conveying of the resource such as petroleum and natural gas mainly according to
By buried oil pipeline, oil pipeline typically uses carbon steel seamless steel tube, vertical masonry joint electric-resistance-welded steel pipe and spiral weld steel pipe
Deng substantially built on stilts on the ground and two kinds of buried pipeline.During pipeline transportation, except irresistible natural conditions, also wrap
Human factor (pipeline damage and property loss as caused by Dongying especially big stolen case) and corrosive pipeline etc. are included, pipeline can all be made
Impacted with the life-span.Wherein corrosive pipeline is to influence the key factor of pipeline operation and service life, and brings huge warp
Ji loss.
Analysis finds, one, in pipe conveying procedure, there are water, salt, alkali and microorganism etc. in soil, the change of level of ground water,
Change, stray electrical current and rainfall of temperature etc., the moisture formed in oxide-film and compound, air accelerate corrosion rate, and
Moisten and contain microorganism and electrolyte solution in soil and air, cause microbiologic(al) corrosion and galvanic corrosion, so as to cause steel
Tubing giving sufficient strength external corrosion is destroyed；2nd, H is contained in natural gas2S and CO2, have S and H in crude oil2There is O in O, product oil2And H2O etc.,
Occur chemical action with inner-walls of duct, cause heavy corrosion inside pipeline, influence pipeline life.Accordingly, it would be desirable to by pipeline
Inside and outside metal surface coats one layer of Protective substances, extends the service life of oil pipeline.
The coating of existing oil pipeline exist some defects, such as high temperature oil product for a long time wash away under, coating it is attached
Put forth effort to be deteriorated, and the chemical resistance of the appearance such as various chemical mediators for outer contacting in pipeline and microorganism is poor, wherein
Most serious is the H contained in natural gas2S, is always the big problem for perplexing pipeline operation, and traditional oil pipeline coating is difficult
Really prevent H2S erosion, these will all cause pipeline heavy corrosion, shorten the service life of pipeline, and then cause huge
Big economic loss.
The content of the invention
Regarding the issue above, the present invention provides a kind of oil pipeline is with adhesive force is strong, chemical resistance is strong
Aqueous heavy antisepsis epoxy primer.
To reach above-mentioned purpose, present invention employs following technical proposal：A kind of oil pipeline of the present invention is with aqueous heavy
Anti-corrosion epoxy primer, including following component by weight percentage：
Further, described aqueous epoxy resins are water soluble polyether modified epoxy, and the water soluble polyether changes
Property epoxy resin molecular weight be 5000-10000.
Further, described water soluble phenol resin is utilizes α, and β-furylacrylic acid replaces the modified water that formaldehyde is synthesized
Property phenolic resin.
Further, described environmentally friendly cosolvent is one in propylene glycol monomethyl ether, propandiol butyl ether, dipropylene glycol methyl ether
Plant or several combinations.
Further, described ptfe emulsion is the aqueous dispersions of polytetrafluoroethylene (PTFE), the polytetrafluoroethylene (PTFE)
The solid content of aqueous dispersions is 60%.
Further, described curing agent is one or more of in fatty amines curing agent, polyamide-based curing agent
Combination.
Further, the auxiliary agent is one or more of combinations in levelling agent, dispersant, anti-flash rusting agent.
Beneficial effect：Extensively, surface drying time is fast for the storage condition of the present invention, and water-fast, acid and alkali-resistance, oil resistant, salt spray resistance, resistance to
The alternate function admirable of high temperature, cold-hot.Strong shock resistance, adhesive force is good.
Compared with prior art, the invention has the advantages that：
(1) the characteristics of modified water-soluble phenolic resin that the present invention is used is primary is heat-resisting quantity, is highly suitable for high temperature
Oil pipeline；And resol resins another important applications is binding agent, be it is a kind of it is multi-functional, with it is various organic and
Inorganic filler can be compatible material, after crosslinking have extremely strong adhesion strength, greatly improve the adhesive force of coating；Phenolic resin
The decomposition of chemical substance, such as gasoline, oil, ethylene glycol can also be resisted, its anti-chemical stability is strong.Especially acid resistance
By force, the problem of greatly improving oil pipeline acid resistance difference now.
(2) ptfe emulsion that uses of the present invention has a series of premium properties, assigns film excellent water-fast
Property and weatherability.The every excellent chemical moral character energy itself having, and common water-base epoxy anti-corrosion primer, there is weatherability
Can not be good the characteristics of, but add after ptfe emulsion, weatherability is greatly improved, while also enhancing the anti-of epoxy primer
Rotten performance.Long-term 200-260 DEG C of high temperature resistant itself, is resistant to all organic solvents and chloroazotic acid by low temperature resistant -100 DEG C, defeated to resist
The chemical erosion that oil-piping is subject to；The ageing-resistant life-span is good, there is self lubricity and non-stick, nonhazardous.Also excellent electric insulation
Property, do not influenceed by temperature and frequency, anti-stick corrosion-inhibiting coating is made.
(3) phenolic resin and epoxy resin compounding use, have the advantage of two kinds of resins concurrently, while using polytetrafluoroethylene (PTFE) breast
Liquid, makes water-base epoxy anti-corrosion primer have the premium properties such as strong, acidproof, the alkaline-resisting, high temperature resistant of adhesive force, and due to phenolic resin
Effect, epoxy anticorrosion primer also improves ageing-resistant performance.
(4) modified water-soluble phenolic resin is selected, while compounding epoxy resin, the caking property of epoxy resin is improved, makes pipe
The Adhesion enhancement in road, because the most important advantage of phenolic resin is heat-resisting quantity, can meet the heat resistance of high temperature oil pipeline
It can require, and be greatly improved for the acid resistance of epoxy resin, chemicals-resistant stability is improved.
(5) aqueous heavy antisepsis epoxy primer produced by the present invention has the performances such as certain high temperature resistant, chemicals-resistant, even if
Oil pipeline also will not cause corrosive pipeline to destroy easily under hot and humid and strong acid and strong base, and caking property is strong, and adhesive force is excellent
It is different, pipe surface disbonding will not be caused easily, the service life of pipeline is extended, very big financial cost is saved.
