Definitions
- the invention relates to a method for applying phosphate coatings on metal surfaces by means of phosphating solutions based on zinc phosphate as an essential layer-forming component, which are accelerated with chlorate and water-soluble aromatic nitro compound.
- GB-PS 1 542 222 provides for the use of chlorate and nitrobenzenesulfonate as accelerators in zinc phosphate processes.
- the weight ratio of chlorate to nitrobenzenesulfonate should be 3: 1 to 5: 1.
- DE-OS 30 04 927 also describes a process for phosphating metal surfaces with zinc phosphate solutions, which may contain nitrite and / or organic nitro compound and optionally additionally chlorate.
- the amounts of nitrite should be 0.01 to 0.2 g / 1
- the amounts of organic nitro compound and optionally chlorate should be in the range of 0.05 to 2 g / 1.
- the active bath components can be introduced in the form of water-soluble or acid-soluble salts or compounds or as acids in water. Suitable are e.g. Zinc nitrate, zinc oxide, zinc carbonate, acid zinc phosphate as well as phosphoric acid, mono- or disodium phosphate and alkali chlorate.
- the water-soluble aromatic nitro compound should have no more than two nitro groups.
- nitrobenzoic acid is suitable.
- Another preferred embodiment of the invention consists in bringing the metal surface into contact with a solution which contains 2 to 7 g / l of nitro compound.
- Optimum phosphate film forming chichta respect fine grain, and S is generally obtained if according to a further preferred embodiment the ratio between C10 3 to nitro compound is set to a value in the range from (0.5 to 1.25): 1.
- the solutions used to produce the phosphate coating can have further components if necessary. For example, it is advantageous to bring solutions in contact with the metal surfaces that additionally contain 2 to 9 g / 1 NO 3 .
- phosphating solutions used additionally contain 0.2 to 4 g / 1 fluoride ions.
- the fluoride can be present in the phosphating solution as free or as a complex-bound fluorine ion.
- Suitable complex fluorides are, for example, fluoborates and / or fluosilicates.
- phosphating solutions which contain an additional content of Ni, Co and / or Fe ions are advantageous. These ions should preferably be present in a total amount of 0.1 to 2.5 g / l. Such additives can expediently be used in conjunction with 0.2 to 4 g / l of the aforementioned simple or complex fluorides. Such phosphating solutions with contents of Ni, Co and / or Fe ions and simple and / or complex fluorine ions are also advantageous for the treatment of surfaces consisting of several metals. Fluorine contents of up to 1 g / l are generally sufficient.
- the 2.9 to 3.2 has a pH value of 2 to 3.5, preferably.
- the phosphating solution should have 5 to 30 points total acid and 0.3 to 2.5 points free acid.
- the number of points is defined in the usual way. For example, the amount of 0.1 n sodium hydroxide solution (in ml) consumed before the bromphenol blue is handled is equal to the number of free acid and the consumption when handling phenolphthalein is equal to the total acid score.
- the number of points can also be determined by potentiometric titration.
- the phosphating solution can be applied in any manner. Dip and spray treatments as well as combined dip / spray treatments are particularly suitable.
- the duration of exposure depends on the desired phosphate layer formation and on the process conditions, but also on the nature of the metal surface and the preceding treatment.
- the treatment times are generally in the range from 0.5 to 3 minutes.
- g ewichte layer from about 0.86 to 1.60 g / m 2 (for steel), 1.30 to 2.15 g / m 2 (for galvanized steel) and to 0.43 g / m 2 (for aluminum) adjustable.
- the respective value results from the accelerator ratio used, the layer weight decreasing as the proportion of aromatic nitro compound increases.
- the phosphating solution used in carrying out the process according to the invention is usually prepared from a concentrate and diluted accordingly.
- the free acid content in the concentrate can be sufficiently high must be set in order to safely avoid solids separation during storage or transport.
- the appropriate pH value or the free acid content is then set.
- the working phosphating solution can be supplemented using a supplementary solution which contains all the active ingredients or using several supplementary solutions which contain all of the active ingredients in their entirety.
- a supplemental solution can contain zinc and phosphate ions and optionally nitrate and / or fluoride and / or nickel ions and another supplementary solution can contain alkali ions, nitrobenzenesulfonate and chlorate ions.
- the inventive process takes place within a conventional Aidsgan there g, consisting of cleaning, water rinsing, phosphate film forming, water rinse, post-treatment and rinsing with deionized water application. This can be followed by a painting treatment or another type of coating.
- the layers produced by the process according to the invention are very fine-grained and permit excellent anchoring of a lacquer coating applied subsequently.
- the Phosphatüberzü received g e provide good corrosion protection and have good physical properties, particularly when the subsequent coating by electrodeposition coating, specifically, is carried out by cathodic electrodeposition coating and thereby treated steel surfaces, galvanized surfaces or aluminum.
- the method according to the invention is also characterized by reduced sludge and crust formation in the phosphating device.
- By changing the accelerator ratio it is finally possible to adapt the quality of the phosphate layer with regard to layer weight and fine grain to the respective requirements.
- Concentrag A was first prepared by mixing the following ingredients in a stainless steel container:
- a phosphating solution intended for spray treatment was prepared from both concentrates by were made up to 1 1 with water.
- the total acid score was 13 when titrating a 10 ml bath sample with 0.1N sodium hydroxide solution against phenolphthalein.
- Examples 2 to 4 were carried out again, with the difference that the phosphating in stage 3.) according to Example 2 was carried out by immersion treatment at 49 ° C. for 1 minute.
- the sheet qualities treated in this way also showed test results similar to those in Examples 2 to 4.
