Abstract
The present invention relates to a kind of preparation method of rust preventive for metal surface, its composition (w%) is: alkyd varnish 30～40, toluene 28～30, ethyl acetate 20～30, isopropylcarbinol 10, aluminium powder 0.5～1.5.Above-mentioned five kinds of compositions take by weighing a certain amount of container that places by weight, after mixing, get ten portions of above-mentioned mixed solutions and add 2～4 parts of propellants (weight ratio), and aerosol is made in tinning.
The rust-preventive agent of the present invention's preparation can change the electrochemical mechanism of traditional alcohols rust-inhibiting paint into the rust-proof mechanism that paint film shields, and it can be widely used in the antirust of metal solder groove, and the directly welding of need not polishing can reduce labor intensity, and raises labour productivity.
Description
The present invention relates to a kind of preparation method of rust preventive for metal surface.
Nature does not have pure iron, how to exist with oxide form, so iron is unsettled on thermodynamics, gets rusty under the oxygen in atmosphere, moisture content and the medium effect thereof, is commonly referred to as wet corrosion.Naturally this change procedure is quite complicated; the iron rust that is generated is formed also complicated; from metal rusty scale state; the top layer is that soft Huang rust is easy to remove; the internal surface rust is that one deck adheres to very firm rusty scale; it is generally acknowledged that it can shield, detect this rusty scale by 10% left and right sides iron rust acid, 50～60%Fe through X ray
3O
4Form with the oxide compound of the unbodied iron in 30% left and right sides.
Metal level is antirust to be very important work of metal-processing industry, along with metallic substance Application Areas difference is also variant to the rust-preventive agent performance demands, antirust problem as the large-size thermal power plant generator tube, with the 100MW unit is example, a unit boiler has 2～30,000 weld bonds approximately, boiler tube is installed resting period approximately about half a year from the construction unit of dispatching from the factory of manufactory, the boiler tube bevel for welding is outdoor storage during this period, groove corrosion during storage is serious, need polish to groove before welding.Therefore workload greatly influences erection schedule, and labour intensity is big, and inefficiency need be sought a kind of special rust-preventive agent, should guarantee that boiler tube deposits non-corrosive, guarantees to be with the lacquer welding again, and does not influence the welding quality of weld bond, i.e. weldability and rust-preventing characteristic.
In recent years, for fear of rust corrosion, the development of rust-preventive agent and antirust technology is also maked rapid progress, relevant alcohol acids rust-inhibiting paint kind is a lot, aluminium powder alkyd oven dry heat-resisting varnish as chemical industry press " coating use technology " first fascicle record, system is mixed together by 70% alkyd varnish and 30% aluminium powder, heat-resisting and the erosion shield that is used for various metal productss surface, another kind of cloud iron alcohol acid antirust paint, be by adding aluminum paste behind pentacite and the mica-iron oxide pigment mixed grinding, catalyzer and organic solvent are made, and are used for outdoor large iron structure and outdoor boiler surface and do antirust bottoming application.Also has a kind of ferro-aluminum alcohol acid antirust paint; by pentacite; resol; after aluminium powder and iron oxide red mixing are milled; adding siccative and No. 200 varnish makers' and painters' naphtha makes; be used for boat segmental rust cleaning bottoming and other metal construction rust cleaning bottoming application; in general Synolac content is higher is everlasting more than 50% for these alcohol acids rust-inhibiting paints; therefore it is dry that rate of drying slowly often needs about 20 hours ability; so be unfit to do groove rust-preventive agent; add metallic powdery pigment in traditional in addition rust-inhibiting paint and make rich zinc or rich alumin(i)um paint; the common metal content of powder is all more than 30%; antirust mainly is to utilize the electropotential of Zn and Al low than Fe; so electronics flows to iron and steel from Zn or Al; iron and steel just is subjected to anodic protection; but high-load Zn or Al are very big to the welding performance impact, influence weldquality and cause the weld bond crack, need dispose when therefore welding; labour intensity is big, and labour productivity is low.
The objective of the invention is to overcome the deficiency of prior art existence, a kind of compound method of new metal antirusting agent is provided, the electrochemical mechanism that metallic pigment are antirust changes the rust-proof mechanism of paint film shielding into, reduce metal-powder content and make rust-preventive agent have weldability and rust-preventing characteristic, raise labour productivity.
Implementing technical scheme of the present invention is:
1, rust-preventive agent composition (W%) is:
Alkyd varnish 30～40
Toluene 30～28
Ethyl acetate 30～20
Isopropylcarbinol 10
Aluminium powder 0.5～1.5
2, rust-preventive agent preparation method
Above-mentioned five kinds of compositions are taken by weighing a certain amount of tempering tank that places by weight, and after mixing, mixing solutions adds propellant by 10: 2～4 part by weight, and blowing type aerosol is made in tinning.
3, using method
Apart from metallic surface 20～30mm,, treat to get final product behind the drying varniss to antirust spraying 1～2 time.
4, rust-preventive agent performance
(1), in air, can seal up for safekeeping more than half a year, but varying environments such as also acid-and base-resisting, salt atmosphere.
(2), can be used for the antirust of metal solder groove, the directly welding of need not polishing does not influence welding property.
The present invention compared with prior art has following characteristics:
1, the rust-preventive agent of the present invention's preparation is a kind of special rust-inhibiting paint, has both had the metal rust preventing function, can be with the lacquer welding again, and does not influence the welding quality of weld bond, is that existing rust-inhibiting paint is not available.
2, the rust-preventive agent of the present invention's preparation, the electrochemical mechanism that the traditional coating metallic pigment are antirust changes the rust-proof mechanism of paint film shielding into, makes the band rust be welded into possibility.
3, the rust-preventive agent of the present invention's preparation is applicable to the antirust of metal solder groove, and the directly welding of need not polishing is raised labour productivity, and reduces labor intensity.
Embodiment:
Take by weighing the alkyd varnish of 0.35kg respectively, 0.29kg toluene, 0.25kg ethyl acetate, 0.1kg isopropylcarbinol and the aluminium powder of 0.01kg, place beaker, after stirring, the mixed solution of getting 0.5kg joins in 2 metal aerosol bottles for 2 parts, add the butane propellant of 0.1kg again, on filler, seal, promptly make 2 bottles of (each 0.5kg) blowing type rust-preventive agent.
Claims (2)
1, a kind of preparation method of rust preventive for metal surface is characterized in that rust-preventive agent composition (W%) is:
Alkyd varnish 30～40
Toluene 30～28
Ethyl acetate 30～20
Isopropylcarbinol 10
Aluminium powder 0.5～1.5
Above-mentioned five kinds of compositions are taken by weighing a certain amount of mixing tank that places by weight, after mixing, get ten parts of above-mentioned mixing solutionss and add 2～4 parts of propellants (weight ratio), aerosol is made in tinning.
2, the method for claim 1 is characterized in that rust-preventive agent is used for the antirust of bevel for welding, can directly be with the film welding.
