Definitions
- the invention relates to a phosphating solution and a method for phosphating surfaces made of steel, zinc, aluminum or their alloys in each case. It is particularly suitable for the phosphating of electrolytically galvanized or hot-dip galvanized steel.
- the phosphating solutions are not rinsed off with water in the sense of a so-called "no-rinse process" after the intended duration of action on the surfaces, but dried directly.
- the method is therefore particularly suitable for use in continuously running strip treatment plants.
- the phosphating of metals pursues the goal of producing firmly adherent metal phosphate layers on the metal surface, which in themselves improve the corrosion resistance and, in conjunction with lacquers and other organic coatings, contribute to a substantial increase in lacquer adhesion and resistance to infiltration Corrosion stress contribute.
- Such phosphating processes have been known for a long time.
- low-zinc phosphating processes in particular have recently been preferred, in which the phosphating solutions contain comparatively low contents of zinc ions of e.g. B. 0.5 to 2 g / 1.
- phosphate solutions which contain 1.0 to 6.0 g / 1 zinc and 8 to 25 g / 1 phosphate.
- Other optional components are nickel, cobalt, manganese, magnesium and calcium in amounts of 0.5 to 5.0 g / 1 each, iron (II) in amounts of up to 2 g / 1 and copper in amounts of 3 to 50 mg / 1 .
- DE-C-2739066 describes a phosphate process in which water rinsing is undesirable from an environmental and cost point of view can be dispensed with.
- the surfaces are brought into contact with a phosphating solution at a temperature of 50 to 75 ° C. for a period of 1 to 5 seconds, which contains 0.1 to 5 g / 1 zinc, 1 to 10 parts by weight of nickel and / or cobalt per part by weight of zinc, 5 to 50 g / 1 phosphate and 0.5 to 5 g / 1 hydrogen peroxide as accelerator.
- a phosphating solution at a temperature of 50 to 75 ° C. for a period of 1 to 5 seconds, which contains 0.1 to 5 g / 1 zinc, 1 to 10 parts by weight of nickel and / or cobalt per part by weight of zinc, 5 to 50 g / 1 phosphate and 0.5 to 5 g / 1 hydrogen peroxide as accelerator.
- phosphating solutions with a zinc content of more than 5 g / l
- EP-B-141 341 also describes a phosphating process in which rinsing with water is dispensed with. This method was developed in particular for stationary structures such as bridges or the like. Accordingly, treatment is carried out with a solution which contains 1 to 5% by weight of zinc, 1 to 20% by weight of phosphoric acid, 0.01 to 0.5% by weight of cobalt and / or nickel and 0.02 to 1.5 Contains wt .-% of an accelerator. After the application of the phosphating solution, which can be carried out, for example, by wiping, brushing, brushing, rolling up or spraying on, the solution is left to act for an unspecified time, during which the solution reacts or only partially reacts. In both cases, you can rinse after exposure.
- the phosphating solution described above has high contents of zinc and phosphate.
- Phosphating solutions in similar concentration ranges are also known for depositing phosphate layers on metal parts which are to be subjected to cold mechanical shaping, for example by drawing or pressing.
- the relatively thick phosphate layers which separate out here and which can be impregnated with oil to increase their effectiveness act as lubricants. medium and reduce the friction between tool and workpiece. They are usually not suitable as pretreatment before painting, since the paint adhesion on the thick phosphate layers is only poor under mechanical stress.
- a phosphate solution which can be used to form phosphate layers on steel strip or wire as a lubricant before cold drawing or other deformations, is described, for example, in DE-B-2552 122. Accordingly, solutions are used which contain zinc in an amount of 5 to 100 g / 1 and phosphate in an amount of 10 to 150 g / 1 and nitrate acting as an accelerator in an amount of 10 to 80 g / 1. The phosphating solution is brought into contact with the surface for a period of 5 to 15 seconds and then rinsed off with water.
- the object of the invention is to provide phosphating processes and phosphating solutions which are intended for use in continuously running belt systems and in which washing of the treated surfaces with water can be dispensed with.
- the invention relates to a method for phosphating surfaces made of steel, zinc, aluminum or their alloys in each case by treatment with acidic, zinc and phosphate-containing solutions and drying the solutions without intermediate rinsing, characterized in that the surfaces be brought into contact with a phosphating solution which
- the phosphating solution contains and has a pH in the range of 1 to 4. Zinc concentrations between 5 and 25 g / 1 are preferable because of the increased process reliability. If the requirements for the corrosion protection effect are not too high, for example for use in the household appliance sector, it is sufficient to use zinc as the only layer-forming cation. For improved corrosion protection, as is required, for example, for use in vehicle construction, it is preferred to use a phosphating process in which the phosphating solution additionally contains 2 to 25 g / 1 manganese ions, preferably 5 to 25 g / 1 . In addition or instead of this, the phosphating solution can contain further components to optimize the properties of the phosphate layer for the intended use of the pretreated material.
- the phosphating solution can also contain one or more divalent metal ions in amounts of 0.1 to 15 g / 1 each included, these additional metal ions are preferably selected from nickel, cobalt, calcium and magnesium.
- the phosphating solution can contain iron in amounts of 0.01 to 5 g / 1 and / or 3 to 200 mg / 1 copper ions.
- fluoride in free or complex-bound form for example as fluorocomplexes of boron, silicon, titanium or zircon, can have a favorable effect on the layer formation. This is the case in particular in the phosphating of hot-dip galvanized steel.
- the effective fluoride limits are between 0.01 and 5 g / 1.
- the phosphating solutions tend to be unstable. They can be stabilized by adding 0.1 to 100 g / 1 of a chelating hydroxycarboxylic acid with 3 to 6 carbon atoms. Examples of such hydroxycarboxylic acids are lactic acid and in particular citric acid and tartaric acid.
- the free acid content of the phosphating solution is preferably in the range from 0 to 100 points.
- the free acid score is determined by titrating 10 ml of the phosphating solution with 0.1 N sodium hydroxide solution up to a pH of 3.6. The consumption of sodium hydroxide solution in ml indicates the free acid score.
- the score of free acid is therefore 0.
- the score of free acid is therefore 0.
- the free acid score is then negative and is equated with the negative sign of consumption of hydrochloric acid in ml.
- the total acid content is determined by titrating 10 ml of the phosphating solution with 0.1N sodium hydroxide solution up to a pH of 8.5.
- the consumption of 0.1 n sodium hydroxide solution in ml gives the total acid score.
- the total acid is preferably in the range from 40 to 400 points.
- the ratio of free acid to total acid is preferably adjusted so that it is in the range from 1: 4 to 1:20.
- Phosphating solutions which have a temperature in the range from 15 to 80 ° C., in particular in the range from 20 to 40 ° C., are preferably used.
- the active substance content of the phosphating solutions should be in the range from about 5.5 to about 35% by weight.
- the active substance content is defined as the sum of the metal ions, phosphoric acid and optionally other components mentioned above.
- the process is particularly designed for phosphating running metal strips in strip treatment plants, such as those found in steel mills.
- a liquid film coating of 2 to 10 ml of phosphating solution per metal surface is preferably applied to the surfaces.
- the optimal value of the liquid film layer depends on the active substance content of the Phosphating solution and on the other hand from the plant-specific exposure time of the phosphating solution.
- layer weights of the phosphate layers in the range of about 0.3 to about 3 g / m 2 are obtained with liquid film coatings of about 6 ml / m 2, as used as the basis for a subsequent painting is desirable.
- the higher the concentration of the phosphating solution the lower the liquid film coating.
- the application of the phosphating solution to the surface and the setting of the desired liquid film overlay can be carried out by different methods. For example, it is possible to spray the phosphating solution onto the surface in such a way that the desired liquid film coating is obtained. A higher level of procedural safety is achieved, however, if the liquid film layer is specifically adjusted after the phosphating solution has been sprayed on, for example by blowing off with compressed air or preferably by squeezing rollers. Instead of spraying on, the phosphating solution can also be applied to the surface by application rollers, the desired liquid film coating being able to be set directly. Such application rollers are known for the surface treatment of metal strips, for example under the name "chem-coater" or "roll-coater".
- the method can be carried out in such a way that the surfaces are immersed in the phosphating solution.
- Metal strips can, for example, be passed through the phosphating solution, the desired liquid film layer being set on the surface after leaving the phosphating solution, which can be done, for example, by blowing with air or preferably with squeezing rollers.
- the optimal process parameters depend on the specific material properties of the surfaces to be treated.
- Example It has been found that, when treating surfaces of running belts made of hot-dip galvanized steel, optimum phosphating results are obtained when the phosphating solution has an active substance content in the range from 5.5 to 35% by weight.
- the preferred pH is in the range from 1.0 to 2.2 and the weight ratio of the sum of the divalent metal ions to phosphate is preferably set in the range from 1: 5 to 1: 6.
- the presence of free or complex-bound fluoride in the phosphating solution has a favorable effect on the layer formation.
- Fluoride concentrations in the range of 0.5 to 1.5 g / 1 are particularly effective.
- Free fluoride is preferably used in the form of hydrofluoric acid, complex fluorides are preferably used as fluoro acids of boron, silicon, titanium and / or zircon.
- alkali fluoride or acidic alkali fluorides such as HF2 to provide free fluoride is also possible.
- the bath stability can be improved by adding about 1 to 10% by weight of a chelating hydroxycarboxylic acid having 3 to 6 carbon atoms, for example by means of lactic acid and preferably citric acid and / or tartaric acid.
- accelerators that is to say substances which promote the formation of layers due to their oxidizing or reducing action, is not necessary in particular in the treatment of galvanized steel. However, they can be advantageous if the formation of certain crystal shapes is desired.
- Suitable accelerators are the compounds known in the relevant prior art, in particular nitrate, nitrite, chlorate, nitrobenzenesulfonic acid or hydrogen peroxide.
- Hydroxylamine can be used as a rather reducing accelerator. Hydrogen peroxide and hydroxylamine can be used as such, the other accelerators mentioned as free acids or in the form of salts soluble in the phosphating solution.
- the liquid film remaining on the surface after the application of the phosphating solution is not rinsed off but dried.
- the surfaces are preferably heated to a temperature between 50 and 120 ° C., in particular between 60 and 90 ° C.
- the treated steel strip can be passed through a drying oven set to the appropriate temperature.
- the drying can also be carried out by blowing the surfaces with hot gases, preferably with air and / or by the action of infrared radiation. Since the acidic phosphating solution can react chemically with the metal surface as long as it is still liquid, the effective exposure time is given by the time between the first contact of the surface with the phosphating solution and the complete drying of the liquid film on the surface, i.e. the End of drying. This time period is preferably in the range between approximately 3 and approximately 60 seconds.
- phosphate layers with a layer weight in the range from 0.3 to 3 g / m 2 are produced on the surfaces.
- Layer weights in this area are particularly desirable as the basis for subsequent painting, since this means that the two requirements of corrosion protection and paint adhesion are met to a particular extent at the same time.
- layers are obtained which do not provide any reflections in X-ray diffraction studies, that is to say can be described as X-ray amorphous, or layers in which more or less pronounced reflections of Hopeit can be observed.
- the metal sheets pre-phosphated by the process according to the invention can be used in particular in the manufacture of vehicles. It is the rule here that the vehicle bodies according to the assembly is phosphated again and then painted, for which cathodic electrocoating is currently customary. In these cases, the material pre-phosphated by the process according to the invention is transported to the further processor in the unpainted state. To improve the temporary corrosion protection during storage and transport, the phosphated material can also be oiled. This will make subsequent forming operations easier at the same time. Post-phosphating the assembled bodies after alkaline cleaning is possible without any problems.
- the phosphating according to the invention can also be immediately followed by a coil coating with an organic film or a lacquer.
- coil-coating is common for this process. In this way, coil-coated material is currently preferred for the construction of household appliances such as refrigerators and washing machines and for architectural applications.
- the invention relates to an aqueous acidic phosphating solution containing zinc and manganese for phosphating surfaces made of steel, zinc, aluminum or their alloys, characterized in that they
- the phosphating solution can contain one or more of the components specified above in the description of the method.
- the conditions mentioned above also apply to the contents of Zn, Mn and possibly other metal ions, free acid and total acid, which are preferably to be set, as well as the preferred ratio of free acid to total acid.
- steel sheets of the quality ST 1405, steel sheets electrolytically galvanized on both sides (ZE) with a zinc coating of 7.5 ⁇ m each and hot-dip galvanized steel sheets (Z) with a zinc coating of about 10 ⁇ m were used.
- the sheets each had the dimensions 10 cm x 20 cm.
- a commercially available mildly alkaline cleaner Rosinline R 1250 I, Henkel KGaA, Düsseldorf.
- the no-rinse treatment was simulated by pouring the treatment solution in a paint spinner (model 4302 from Lau GmbH) and at 550 rpm. was thrown out.
- the layer weight was determined as a parameter for the phosphate layer obtained. Two different methods were used for this: When determining the layer weight by weighing, the sheet was weighed before the coating was carried out, after which the phosphating solution was applied and dried and the coated sheet was weighed again. The layer coverage in g / m2 was calculated from the difference in weight. When determining the layer weight by detaching, the phosphated sheets were weighed, the phosphate layer was removed by detaching with 0.5% by weight chromic acid solution, and the sheets were weighed again. The mass of the removed layer g / m 2 was determined from the difference in weight.
- the layer weight determined by detachment is generally higher than that determined by weighing, since part of the metal surface is converted into metal phosphate by the phosphating becomes. This part is not included in the determination of the layer weight by weighing, but is also removed when the layer is detached.
- Table 1 contains phosphating baths for electrolytically galvanized steel and the layer coatings obtained, table 2 corresponding examples for the treatment of hot-dip galvanized steel.
- phosphating solutions are suitable, which lead to layer weights in the range of 1 to 3 g / m2.
- Zinc as oxide, manganese and nickel as carbonate and fluoride as sodium fluoride were used in the exemplary treatment baths.
- the baths contained no components other than water.
- the layer composition was determined by means of EDX (X-ray emission) (in% by weight): Zn 7.5, Mn 2.2, P 7.5, AI 0.3, rest: can be taken up as oxygen.
