Description
Technical field
The present invention relates to polyureas technology, relate in particular to a kind of petroleum pipe line end socket polyaspartic ester type seal gum and preparation method thereof.
Background technology
Along with the development of national economy, the advantage of pipeline oil transportation highlights day by day.General the employing built on stilts or buried two kinds of modes on the ground of laying of oil pipeline.But no matter take that mode, in the time that metallic conduit contacts with surrounding medium, cause its surface corrosion owing to there is chemical action or electrochemical action.This phenomenon is very general.After metallic conduit is corroded, all will change in profile, color and luster and mechanical property, and affect the quality of institute's oil transportation product, and shorten the work-ing life of oil pipeline, and seriously may cause leakage, contaminate environment, even can not be used.
The common corrosion of petroleum pipe line comprises chemical corrosion and galvanic corrosion.Chemical corrosion: exposed metal/bare metal, in air, while contact, generates corresponding compound (oxide compound, sulfide, muriate etc.) with airborne oxygen, sulfurous gas, chlorine etc. on metallic surface.The organic sulfide (sulphur, hydrogen sulfide, mercaptan, thioether, epithio ether, disulphide, thiophene etc.) that simultaneously contains various ways in oil product, naphthenic acid etc. also can produce chemical corrosion to metallic oil pipeline.Galvanic corrosion: when metal contacts with electrolyte solution, the corrosion being caused by electrochemistry.Metallic conduit and the atmosphere that contains moisture, soil, ocean contact, carbonic acid gas, sulfurous gas, hydrogenchloride, sodium-chlor and the dust containing in these media is all the electrolyte solution of different concns.
Oil pipeline end socket is the most important structure in whole pipeline, due to the complicacy of its structure, construction and use, in pipe laying, be the position that suffers chemical corrosion the most serious, be also oil seepage, leak the position usually occurring, therefore the sealing at end socket place is extremely important.Find a kind of corrosion-resistant, good sealing effect, and have the sealing material of fine consistency very important with polyurea materials.
At present, protective system for inner and outer walls of pipeline mainly contains the multiple materials such as petroleum pitch, coal tar enamel, clinkery epoxy powder, double-deck welding epoxy powder, 3PE structural anticorrosion layer and spray polyurea material, wherein polyurea materials has more advantage than other materials, having broken traditional preservative coat need to heat and be wound around the defect of bringing, one time coating thickness can reach 1-2mm, this greatly simplifies its coating process, and can guarantee the overall antiseptic property of pipeline.Polyurea materials is that a kind of curing molding growing up is in recent years fast, the ep-type material of constructability.It is high with tensile strength, snappiness good, and the premium properties such as waterproof, protection against corrosion, wear-resisting, anti-slippery, heat shock resistance, low temperature resistant and good decorative property, be subject to people and more and more favor, show unique characteristics at ready coating aspect aspect the big area such as corrosion protection coating and wear-resistant coating.Polyurea materials has excellent physicals, antiseptic property and workability concurrently, is the preferred material in inner and outer walls of pipeline antiseptic project.
Spray polyurea speed of response is fast, gel time is short (only having short tens seconds), can be at comparatively smooth inner and outer walls of pipeline rapid shaping.But spray polyurea is not suitable for complex structure, flex point, the cap that node is many.This be because spray polyurea in the time that cap is constructed, because set time is fast, gel time is short, trickling property is poor, easily causes drain spray and spraying uneven; Wetting property is poor, poorly sealed, and the problem such as easily come off.
The main polyurethane sealant that adopts of petroleum pipe line end socket sealing at present, polyurethane sealant is bonding stable, excellent spring, anti tear, wear-resisting, anti-puncture, does not pollute base material, acid and alkali-resistance, resistance to liquid medium, corrosion-free to concrete, steel substrate etc.Price is gathered sulphur, organosilicon sealant is cheap, and has good consistency (this is that other sealing materials do not possess) with polyurea materials.
Polyurethane sealant is by single component, two kinds of base types of two-pack.The basal component of single-component product is end NCO base performed polymer, and the hydroxyl isoreactivity group generation chemical reaction that can exist with the water of substrate surface absorption and surface after bonding finally generates urea bond structure and solidifies.Single-component mist-solidifying polyurethane sealant is a kind ofly to utilize in air micro-moisture as crosslinking accelerator and curing response type seal gum.Single-component product at room temperature can carry out moisture-curable, operation is easy, but there is following shortcoming in it: single component sealant package stability packed and ectocine larger, conventionally solidify slower, under high humid and warm environment, solidify and may produce bubble and crackle, affect use properties and work-ing life, and many occasions need primary coat.
Double Component Polyurethane Sealant is solidified by the NCO base of base polyurethane prepolymer for use as and the active hydrogen compounds cross-linking reaction of another component.Self-vulcanizing speed is faster than single component, and cost value is lower, but still has following shortcoming as the sealing material at petroleum pipe line end socket place:
A. the more anticorrosion polyureas of sticking power is poor.Polyurethane sealant and polyurea materials belong to polyurethane system, the consistency of bi-material is better, but also there is certain difference in the two: the tensile strength >=20MPa of polyurea materials for pipeline corrosion protection, elongation at break >=10%, hardness is high, in polyurethane system, belong to rigid material, to the sticking power excellence (sticking power >=9MPa) of steel substrate.Tensile strength >=the 6Mpa of polyurethane sealant, elongation at break >=100%, hardness is low, belongs to flexible materials in polyurethane system, in without primary coat situation, the poor adhesive force (sticking power >=2.5MPa) to steel substrate.
B. resistance to liquid medium, oil-proofness are not as polyurea materials.In polyurethane sealant, contain a large amount of amino-formate bonds, this bond polarity can not show a candle to urea bond polarity in polyurea materials.Therefore polyurea materials is finer and close, oil resistant, resistance to liquid medium more.Can not show a candle to polyurea materials at polyurethane sealant aspect this.
C. in polyurethane sealant, contain a large amount of aromatic isocyanate polymkeric substance, xanthochromia is serious, and weather resisteant is poor, and resistance of aging is poor.
Summary of the invention
