Abstract
The present invention relates to paint for metal pipe and rod and its production process. The metal pipe and rod has as least one layer of hydrophobic and oleophobic coating. The paint of the present invention includes nano material 0.001-1 wt%, filming material 40-79 wt%, pigment and stuffing 20-50 wt%, and assistant 0-39 wt%. The metal pipe is first painted with the paint in the inner wall and then in the outer wall, and the metal rod is painted with the paint with the coating is cured at 200 deg.c inside a cure furnace for 40 min. The addition of the nano material changes the property of the paint and makes the surface of the coating hydrophobic, oleophobic and anticorrosive.
Description
Technical field: the present invention relates to the used coating of two manufacture methods of dredging (oleophobic is hydrophobic) coatings of metal tube, bar metal surface and coating and the manufacture method of this coating.
Background technology: in the pipeline accident of China, the destruction that corrosion causes accounts for 30% according to statistics.Many especially in recent years field produces exploitations enter the later stage, and water content in crude oil increases, ageing equipment, and etching problem is more and more serious.Oil that China produces belongs to low-sulfur, paraffinic base crude oil mostly.The crude oil of extraction is from the process that carry earthward the depths, stratum, along with the reduction of temperature, pressure and separating out of gas, the paraffin that dissolves in the crude oil just begins to separate out, wax crystallization is assembled and is deposited on tube wall and the sucker rod, the wax deposition phenomenon just occurs, increases oil flow resistance after the oil well paraffinication, even cause wax card, oil pipe to stop up, increase wax removal operation number of times, not only can increase cost for oil production, also can have a strong impact on production.This shows the inwall and the sucker rod of oil recovery pipeline in the oil exploitation, except that anticorrosion, the meaning of anti-wax deposition is very outstanding." three anti-" in recent years (promptly anticorrosion, antiscale, anti-wax deposition) technology constantly develops, adopt coating technology to become the important means of anticorrosion, antiscale and anti-wax deposition at the oil gas field duct wall, formed multiple material, be liquid coating (comprising epoxy coating, polyurethane coating etc.), epoxide powder coating, glass flake anticorrosive coat, cement-mortar lining, glass reinforced plastic lining and zinc-rich paint etc.Liquid epoxy coating at home and abroad field use is more, and kind also has multiple.The advantage of this type of anticorrosive coat is and the strong adhesion of metal, and good decay resistance (acid and alkali resistance, salt organic solvent, water-fast etc.) is arranged, mechanical performance and electrical insulation capability preferably, and such anticorrosion medium temperature that is applicable to is less than 65 degree.Epoxide powder coating, this kind corrosion-inhibiting coating has good Corrosion Protection, adhesive property, long service life, good insulation preformance, suitable operating temperature is below 100 degree.The pipeline cement-mortar lining is that a kind of applicating history is long, material source extensively, easy construction, nontoxic, economic interior anti-corrosion material.Be mainly used in clear water, sewage conduct, the pH value of institute's pumped (conveying) medium must not be lower than 5, and temperature should not be higher than 60 degree.Above-mentioned various petroleum industry is recovered the oil and the domestic and international anticorrosive paint technology of filling pipe, though characteristics are respectively arranged, these type anticorrosive paints do not possess oleophobic and hydrophobic characteristic simultaneously, especially anti-wax deposition effect is not had positive effect.Its reason is the consideration in the coating surface function design, lacks theory and practice and instructs, and considers that just coating surface is smooth, reaches the purpose that surperficial oleophobic is realized wax control by coating surface is hydrophilic, and practice shows: wax control result is unsatisfactory; Because hydrophilic surface can cause fouling, and then form new wax deposition core again and make surperficial wax deposition.In addition, as can be seen, the coating major part that they obtained all is the surface of hydrophobic oleophylic from existing three-resistance coating, and the anti-wax deposition performance in such surface is just more weak.
Summary of the invention: the objective of the invention is to develop a kind of hydrophobic, oleophobic that has, make metal tube, bar have three anti-(anticorrosion, antiscale, the anti-wax deposition) coating of suburb fruit and manufacture method of its method for making and the used coating of this coating and this coating, it should have can use for a long time, not delamination, the good characteristics of anti-aging, immiscible property.At least be coated with intrinsic layer of surface on the metal surface of metal tube of the present invention, bar 1 and be two coatings 2 of dredging, the thickness of coating 2 is 5～100 μ m, and the thickness of bottom 3 is 0～150 μ m.Form in the coating of this coating and contain nano material, film forming matter, pigment, filler, auxiliary agent, wherein nano material accounts for 0.001～1% of coating gross weight, film forming matter accounts for 40～79% of coating gross weight, pigment, filler account for 20～50% of coating gross weight, and auxiliary agent accounts for 0～39% of coating gross weight.Described nano material is C23, SiOx, and its granularity is 1～100nm; Described film forming matter is composite high-molecular resin 228A, 228B, TY-54,38 resins; Described pigment, filler are that iron oxide red, ferrophosphorus powder, graphite powder, mica powder, titanium are from powder; Described auxiliary agent is dimethylbenzene, butanols, S329,88-9C, and wherein contained nano material is made up of C23 and SiOx a kind of or its mixing of two kinds wherein; In the contained film forming matter composite high-molecular resin 228A account for the film forming matter gross weight 17～45%, 228B account for the film forming matter gross weight 2～10%, TY-54 30～58%, 38 resins that account for the film forming matter gross weight account for 17～45% of film forming matter gross weight; Contained pigment, filler are made up of one or both the mixing in iron oxide red, ferrophosphorus powder, graphite powder, mica powder, the titanium dioxide; Contained auxiliary agent is by any or several the mixing among dimethylbenzene, butanols, S329, the 88-9C, the preparation method of coating of the present invention is: 1, get the nano material that accounts for coating gross weight 0.001～1%, get the film forming matter that accounts for coating gross weight 40～79%, get the pigment, the filler that account for coating gross weight 20～50%, get the auxiliary agent that accounts for coating gross weight 0～39%; 2, with surfactant nano material is carried out dispersion treatment; 3, add film forming matter, auxiliary agent successively in twin shaft lifting high speed dispersor, add the nano material through dispersion treatment then, add pigment, filler again, high speed dispersion 1 hour makes half-finished mix mill base; 4, the mix mill base after will disperseing carries out levigate dispersion by horizontal sand mill, obtains sand milling to fineness colored paste resin below ten microns; 5, paste resin is removed mechanical admixture and coarse grain by filter plant, be finished product by the bottle placer packing.That the present invention has is anticorrosion, antiscale, the metal tube of anti-caking wax coating, the manufacture method of bar: at first metal tube, bar are carried out blasting treatment, remove grease, the rust of metal surface, go up falsework then, elder generation's primer spray, metal tube be the spraying inwall earlier, sprays outer wall again, Metallic rod directly sprays outer wall, solidify through 40 minutes through 200 ℃ temperature in curing oven then, former falsework is returned in the cooling back, sprays coating of the present invention by the processing step and the process conditions of primer spray.That metal tube, the bar that the present invention contains two open coats has is anticorrosion significantly, antiscale, anti-wax deposition characteristic, anticorrosion reaching more than 10 grades, and the water pipe antiscaling rate reaches more than 98%, the anti-paraffin depositing ratio of oil pipe reaches more than 95%, can use not delamination for a long time in-40～150 ℃ of scopes, anti-aging, incompatibility is good.Manufacture method is simple, easily be automated scale, suitability for industrialized production.
