Description
Technical field
The present invention relates to a kind of anticorrosion anti-corrosive coating, be specially a kind of surface antiseptic treating agent of cable testing bridge.
Background technology
To be for solving automobile bottom metal component be born in the U.S. because the corrosion of antifreeze brinish causes a large amount of vehicle damage to be scrapped to Dacromet Technology at the end of the fifties.The characteristics of its coating maximum are that anti-brine corrosion ability is strong.After the technology of Japanese firm is bought out, studies, is developed and improves, make the Dacroment coating processes day by day ripe, coating performance is better, and is widely used in relevant industries all over the world.The Dacroment masking liquid generally is divided into A, B, three components of C, and wherein: the A component is the silver gray soup compound that flake zinc, aluminium powder and ethylene glycol compounds are formed.The B component is the orange red aqueous solution that is made of dichromate and deionized water.The C component is the tackifier (white powder) based on Mierocrystalline cellulose.The Dacroment masking liquid is coated on the workpiece through about 300 ℃ high temperature and after the barbecue regular hour, generates unbodied compound chromic acid compound.And chromic salt carries out Passivation Treatment to zinc metal sheet, and the zinc metal sheet electroconductibility after the processing is moderate, and is in controlled anode sacrificing protection state, and aluminium flake plays the elutriation effect to zinc metal sheet again, and the control zinc metal sheet is separated out.The mechanical masking layer of Zu Chenging weakens corrosion current layer by layer like this, thereby postpones the speed that is corroded and is separated out of zinc, makes it have extremely excellent erosion-resisting effect.The key of Dacromet Technology is flake zinc powder and aluminium powder, its purpose is that to make extraneous etchant gas reach the path of substrate surface elongated, it is shorter that general electro-galvanizing reaches the path of substrate surface, and Dacromet Technology can make these flake zinc powders form tens of stacked adding at substrate surface, as the wall of laying bricks of building a house, flake zinc dust figure brick is layering together, and has carried out passivation layer by layer, thereby is difficult to make the corrosion thing to arrive the long distance of substrate surface needs.
The Dacroment production technique adopts the coating method of whole process closed cycle, has thoroughly changed electroplating technology, pollution problems such as acid, alkali, chromium and the sewage of having stopped to produce in the electroplating process, exhaust gas discharging.The application of Dacroment is very extensive, and it not only can handle steel, iron, alloy can also handle sintering metal and special surface treatment.High pressure power transmission and distribution, the cable testing bridge of urban electricity supply cable generally all are in outdoor high-altitude, are not only exposed to the sun and rain every day but also are subjected to environmental pollution, and the task of maintaining at ordinary times is very heavy.Fuel tank on the iron tower of ultra-high-tension power transmission line, the cross-arm of electric pole, support iron clamp hoop, elbow, bolt, steel cap, the transformer, fastening piece etc. mostly used ways such as brushing paint, electro-galvanizing, temperature zinc to do surface anticorrosive originally and handled.But the general anticorrosion time of these traditional surface treatments is all shorter, and the top coat of general 2 years left and right sides steel parts will lose efficacy.If using traditional Dyclo paint handles, then steel part also can reach anti-corrosion effects preferably, but because outdoor installations such as cable testing bridge are under the severe environment for a long time, so it is high that its anticorrosion Capability Requirement against corrosion is more wanted, traditional Dyclo paint obviously also is difficult to satisfy these requirements.
Summary of the invention
The present invention is in order to solve the surface antiseptic treating agent that traditional Dacroment anticorrosive coating of existing in the prior art provides a kind of cable testing bridge being difficult to satisfy the etch-proof problem of cable testing bridge.
The present invention is realized by following technical scheme, and a kind of surface antiseptic treating agent of cable testing bridge is made up of according to part by weight following composition,
A component: flake zinc powder 60～80%, flakey aluminium powder 5～15%, dispersing agent NNO 1.5～3.5%, emulsifying agent 2.5～4.5%, water 6～14%, rare earth 2～4%, permeate agent 2～4%, tensio-active agent 1～5%;
Rare earth is 10～40% neodymium and 60～90% gallium (weight ratio).
Permeate agent is ethylene glycol butyl ether, GFC.
Tensio-active agent is alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether, polytrimethylene ether.
B component: chromium trioxide 10～20%, ethylene glycol 8～12%, Si defoamer 3～5%, water soluble resin 6～10%, deionized water 40～60%, hardening agent 8～15%.
Hardening agent is macromolecule resin, water-soluble epoxy resin, water soluble amino modified resin
C component: Mierocrystalline cellulose 60～90%, colloidal state thickening material 10～40%.
The part by weight of A, B two component usage quantitys is 2: 3, and above-mentioned A, B mixture and C component are added the mixed of 1～5 gram C according to per kilogram A, B mixture.
Compare with traditional Dyclo paint, the present invention has increased the ratio of flake zinc powder, and practice shows when having only the flake zinc coating that reaches in the solids component of curing back more than 90% just can reach outstanding preservative effect.Increase rare earth material, can reach more outstanding preservative effect.Increased smooth, the no bubble of coatingsurface that permeate agent (GFC, ethylene glycol butyl ether) and tensio-active agent (alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether, polytrimethylene ether) form the present invention.Particularly increased the problem that hardening agent (macromolecule resin, water-soluble epoxy resin, water soluble amino modified resin) has overcome traditional Dyclo paint scratch resistance weak effect, made the cable testing bridge surface have stronger scratch resistance ability.
The invention belongs to the water-based paint of discrete type, separately preserve at ordinary times, A, B, the on-the-spot preparation of three kinds of components of C are synthesized during use.A, B component are adjusted between 20～28 degrees centigrade, get the A component then and pour stirring in the groove into, evenly stirred 30 minutes with high rotational speed, the B component of getting half then adds in the A component under the state that stirs, continue to stir 30 minutes, and then remaining B component is slowly joined in the above-mentioned mixed composition under whipped state.This process purpose is exactly that each raw material thorough mixing is even, spills into above-mentioned A after at last the C component being disperseed, and stirs in the B mixture and can use.
Make a kind of liquid form mixt after the raw material field mix of the present invention, immersing cable testing bridge wherein, certain hour can form the protective system layer on the surface.1, the formed corrosion protection coating in cable testing bridge surface after handling through the present invention have the conventional surface treatment process incomparable excellent properties, the present invention forms coating on irony parts such as cable testing bridge thickness is 3～12 μ m only, surpass traditional galvanizing, hot-dip process or organic coating cladding process but the preservative effect of this coating is really far away, and its preservative effect also is better than the Dyclo paint that tradition is used.Show that through salt mist experiment the electrogalvanizing of 13～25 μ m thickness promptly produced serious red rust after 48 hours, the galvanizing of 65 μ m thickness also began to get rusty after 160 hours, and the aluminium zinc epithelium that the coating that the present invention of 13～25 μ m thickness forms forms can be anti-to 500～3000 hours, and as seen its antirust ability exceeds more than 10 times than zinc-plate process.
2, test shows, also can not be corroded being positioned over for a long time under the hot conditions even handle the coating that forms through coating of the present invention.And use electro galvanizing or galvanizing method, and because the coefficient of expansion of zinc and iron is different, more than 100 ℃ the time, the coating on steel part surface will be degraded, thus base material exposes and loses protective effect.And the epithelium that uses the present invention to handle steel part formation still has good corrosion resistance at 300-500 ℃ under subzero 100 ℃ environment.Particularly space industry requires part to use in high temperature, high ultraviolet ray, high radiation, high-intensity environment, to possess high Corrosion Protection simultaneously, the present invention can satisfy these harsh requirements simultaneously, as the application in some piece surface of Divine Land series airship is handled.
3, galvanic corrosion can be prevented, galvanic corrosion will be produced, i.e. galvanic corrosion effect when in general two kinds of different metal alloys of electropotential contact aluminium.This phenomenon equally also can occur in the contacted position of aluminum metallic material and galvanized steel.For the cable testing bridge electro-galvanizing is handled, consider that its anticorrosion mechanism is because the raising of the sacrificial etched anticorrosion ability that just causes of metallic zinc, to such an extent as to zinc consumption interior metal is come out having produced the galvanic corrosion effect, and then the galvanic corrosion of aluminium will take place with the contacted position of metallic aluminium.And for the coating that the cable testing bridge that the present invention handles forms; because its anticorrosion mechanism is to be based upon on the controlled sacrificing protection effect of the passive state effect of chromic acid and zinc; so suppressed the consumption of zinc; therefore improved Corrosion Protection stable of cable testing bridge; interior metal is not exposed, and has just suppressed the corrosion of aluminium yet.
4, avoided plating fragility, big characteristics of the cable testing bridge that process the present invention handles are can not electroplate fragility.
5, the present invention is a kind of liquid form mixt under the state that uses, as long as ironware is soaked.So the surface for the iron part of arbitrary shape all can form protective filmy layer.Particularly the place of combining closely for cable testing bridge also can generate anti-rust film.Even tightly rolling up the spring in slit, under stretched state, carry out brine spray after process the present invention handles and test the antirust ability that also can demonstrate more than 1000 hours.
6, can be on the film that forms other coating of application again.Experiment shows, compares with the surface of other zinc-plated formation, and the film that the present invention handles formation has better tack.
7, range of application is very extensive, and it not only can handle iron and alloy thereof, can also handle light metal (as aluminium etc.) and can also handle sintering metal.
8, the course of processing is without any pollution, because the present invention does not use materials such as strong acid or prussiate, to human body safety.The course of processing and the workpiece surface treating processes do not produced any pollutent, and be a closed treating processes, do not wash with water, so without sewage discharge yet.
