Abstract
The invention relates to a non-phosphate film agent, comprising the following components by weight percent: 2.5-4.5% of succinic acid, 0.8-2% of sodium molybdate, 0-3% of sodium nitrate, 0-5% of citric acid, 0-0.5% of sodium fluoride, 0-0.8% of tannin, 0-1.5% of oxalic acid, 0-0.05% of sodium dodecyl sulfate, the balance of water. The invention has the advantages that: the non-phosphate film agentcontains no phosphor, thus being really environmentally friendly; antirust performance is good; combining power with molding powder and paint and adhesive force are all excellent, thus meeting ROHS standard; when in use, aluminum alloy work piece, galvanized work piece and steel work piece can be placed in the same bath solution for coating, thus greatly simplifying the production technology andreducing equipment investment; and suspended matter produced when being continuously used for three months is only 10-20 kilograms, thus solving the difficult problem that one day is stopped in production per week for clearing phosphated slag when using phosphoric film agent.
Description
Technical field
The present invention relates to a kind of non-phosphate film agent, it is used for the preceding operation of coating metal surfaces.
Background technology
Film agent is a kind of metal conditioner; can produce reaction with metal; when removing the metallic surface corrosion; form a kind of water insoluble, unreactiveness, firm attachment protective membrane in the metallic surface; this protective membrane helps preventing burning; also help in follow-up metallic surface spraying process, the engaging force of paint film, molding powder and the metal of spraying, sticking power are strengthened, thereby be widely used in the making industry of metal productss such as automobile, refrigerator, air-conditioning.
Film agent comprises phosphorous film agent and non-phosphate film agent two classes, and phosphorous film agent environmental pollution is serious, in use can produce a large amount of phosphatic waste water and waste residue, and the treatment process of these waste water and waste residue is comparatively complicated, and processing costs is also higher.Though there are some not phosphorous in the existing non-phosphate film agent, contain other objectionable constituent, as fluorine zirconic acid etc., these objectionable impuritiess also can pollute environment; Though also have some non-phosphate film agents not phosphorous, but its effect only is equivalent to rust-preventive agent, itself and metallic surface do not produce oxidation or replacement(metathesis)reaction, behind this non-phosphate film agent processing metal, the protective membrane that forms in the metallic surface can play certain effect that prevents burning, but the engaging force of this protective membrane and paint film and molding powder, sticking power are all very poor, and film of long duration is easy to peel off from the metallic surface; In addition, the non-phosphate film agent that has in use must be used deionized water, in case there is ion to enter production process, just must change medicament.
In addition, different types of film agent generally can only be at film on the dissimilar metal works on the market, for example: the general film agent that contains chromium that uses of Al alloy parts, iron and steel parts is then used phosphorous film agent more, and therefore different metal works can not be placed on when handling goes up film in the same tank liquor.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of non-phosphate film agent, and this non-phosphate film agent in use can be not incrust to the film that environment pollutes and generates.
The technical solution adopted in the present invention is: a kind of non-phosphate film agent, and its component and content are:
Succinic Acid 2.5---4.5%;
Sodium orthomolybdate 0.8---2%;
SODIUMNITRATE 0---3%;
Citric acid 0---5%;
Sodium Fluoride 0---0.5%;
Weibull 0---0.8%;
Oxalic acid 0---1.5%;
Sodium laurylsulfonate 0---0.05%;
Other are water, and all percentage ratios are weight percentage.
According to national regulation, phosphorus content is lower than 15% and promptly can be considered without phosphorus in the film agent.Therefore, all contain the phosphorus of certain composition in the existing non-phosphate film agent mostly, the present invention adopts Succinic Acid and Sodium orthomolybdate to realize basic last film function, and is not phosphorous fully, thoroughly solved the pollution of phosphorus to environment; And for the metal of unlike materials such as aluminium alloy, steel plate, Succinic Acid, Sodium orthomolybdate all can react film forming with it, and therefore different metal works can be placed on when handling goes up film in the same tank liquor; Sodium orthomolybdate can also make the film of generation produce different colors such as indigo plant, purple, gold according to the difference of temperature of reaction, acidity and the sheet metal that reacted, need not to be added with harmful heavy metals, can form firm colored oxide film with the metallic surface; The present invention can also adapt to various water quality.
As preferred version of the present invention, the content of SODIUMNITRATE is 0.2---3%.SODIUMNITRATE is an oxygenant, can improve the speed of film agent film on the metallic surface.
As another kind of preferred version of the present invention, the content of Sodium Fluoride is 0.01---0.5%.Sodium Fluoride can corroding metal, makes the metallic surface smooth, thereby therefore the easier film of going up also can play and improve the effect of going up film speed.
As another kind of preferred version of the present invention, the content of citric acid is 0.05---5%.Citric acid can be regulated the thickness of film.
As another kind of preferred version of the present invention, described non-phosphate film agent comprises the oxalic acid of 0.5---1.5% and/or the sodium laurylsulfonate of 0.01---0.05%, can adopt film on the spraying method during use.Can generate some iron ions when the aqueous solution of Succinic Acid and Sodium orthomolybdate and metal reaction in last membrane process, oxalic acid can chelated iron ion and is improved the acidity of film agent, the effect of film in the raising; In addition, the metallic surface often has some oil, ash, selects the sodium laurylsulfonate tensio-active agent for use, can get rid of these oil, ash well, makes to go up the smooth and even film layer of film.
As another kind of preferred version of the present invention, the content of Weibull is 0.02---0.8%.Weibull itself can generate rete with metal reaction and on its surface, but because the Weibull film formation time is longer, otherwise the rete that produces will be very thin, but therefore film on the adopting soaking method.Adopt Weibull to cooperate film on Succinic Acid and the Sodium orthomolybdate, can make the engaging force of film and metal better, and can guarantee that it can be too not thin.
When making film agent of the present invention, after each raw material dissolves in water and finishes, add a kind ofly down again, the sequencing that adds between the various raw materials is fixing, and temperature is that normal room temperature gets final product.
Use film in the present invention, temperature is 35 ℃--effect is better in the time of-55 ℃.
Advantage of the present invention has: described non-phosphate film agent is not phosphorous fully, real environmental protection; Rustless property is good; All reach good with engaging force, the sticking power of molding powder, paint, meet the ROHS standard.Al alloy parts, galvanized workpiece, iron and steel parts can be placed on during use and go up film in the same tank liquor, simplify production technique widely, reduce facility investment; Use the suspended substance that was produced in three months only to be the 10---20 kilogram continuously, solved and used phosphorous film agent to stop production weekly to remove the difficult problem of phosphatization slag in one day; Use the waste water flocculation agent post precipitation that the present invention produced, do not contain hazardous substance recycling or direct discharging.
