Definitions
- the invention relates to a process for the production of phosphate layers on surfaces which consist partially or entirely of zinc or zinc alloys by means of zinc, phosphate, accelerator and nickel-containing phosphating solutions in dipping or flooding, and its application to the preparation of the surfaces for painting, in particular the Electro dip painting.
- Phosphating solutions for the phosphating of surfaces consisting at least partially of zinc or zinc alloys contain, in particular, zinc and phosphate as components determining the layer formation.
- other cations such as nickel, copper, calcium, manganese and alkali metal can be present to modify the layer formation.
- oxidizing agents e.g. from the group nitrate, chlorate, nitrite, peroxide, organic nitro compounds.
- Other possible additives include Fluoride, complex fluoride, chloride, organic polyhydroxycarboxylic acid, complex phosphates and surfactants.
- the baths are used in the immersion, spraying / immersion and spraying process at temperatures of typically 30 to 70 ° C. and treatment times of, for example, 0.5 to 5 minutes (EP - A - 69 950).
- EP-A-137 540 provides for the electrolytic production of zinc coatings on steel with a sulfuric acid electrolyte solution which contains one or more oxygen acids of the sulfur with an oxidation number of the sulfur of +5 to + 1 contains to work.
- Suitable acids of this type are e.g. sulfuric acid, sulfoxylic acid, dithionic acid and thiosulfuric acid.
- the object of the invention is therefore to design the phosphating process itself in such a way that the formation of specks on any zinc or zinc alloy surfaces is avoided.
- the object is achieved by designing the method of the type mentioned at the outset in accordance with the invention in such a way that the surface is brought into contact with a phosphating solution which, when using chlorate as an accelerator, is practically free of nitrate and nitrite and when using nitrate and / or nitrite as an accelerator is kept practically free of chlorate and chloride.
- the method according to EP-A-69 950 provides, inter alia, for the phosphating of galvanized steel with phosphating solutions which must contain chlorate but expediently also contain nitrate (cf. Examples 1 and 3).
- a further content of nitrate is prescribed in addition to a content of chlorate.
- galvanized steel only provides for a content of nitrite or nitrobenzenesulfonate, but it is pointed out that the use of further oxidation accelerators, for example chlorate, is possible and can be advantageous.
- EP - A - l2l 274 also designated as suitable for the treatment of zinc and zinc alloys works with nitrite accelerated phosphating solutions.
- chlorate is also said to be necessary or desirable.
- any phosphating solutions based on zinc phosphate can be used to carry out the phosphating. They can belong to the so-called low zinc as well as the normal zinc technology. That is, the surfaces can with a phosphating solution in which the weight ratio of Zn to P2O5 is set to l: (8 to 85), or with a phosphating solution in which the weight ratio of Zn to P2O5 is set to l: (0.3 to ⁇ 8).
- phosphating processes result, which are characterized by a higher phosphating speed in comparison to the low zinc processes.
- the phosphate layers they produce have good properties for a wide range of applications in the areas of corrosion protection and non-cutting cold forming.
- aqueous acidic solutions based on zinc phosphate to be used in the context of the invention contain primary zinc phosphate, optionally alkali metal phosphate, and a certain amount of free acid which is matched to the respective bath concentration, type of application and bath temperature.
- the pH of the baths is between 2.0 and 3.9, depending on the process conditions.
- the phosphating solutions can also contain other cations known in phosphating technology, for example Co, Cu, Mn, Ca, Mg, Fe, Na, K, Li, NH4 and others.
- concentrations of the most important of these ions should be: at Mn and Ca up to 5 g / l, preferably up to 2.1 g / l, at Fe (II) up to 8 g / l, preferably up to 5 g / l.
- the use of other anions different from phosphate for example SO4, F, BF4, SiF6, citrate, tartrate, etc., may be necessary or desirable.
- the contact time for the phosphating solution used in the immersion treatment is usually between 1 and 10 minutes. When treating zinc or zinc alloys alone, shorter treatment times, e.g. from 2 to 30 sec., sufficient.
- the temperature of the phosphating solution is approximately 30 to 60 ° C. The lower the temperature, the longer the contact time.
- the measures customary in connection with phosphating processes can also be used in the present process. These are in particular degreasing and rust removal, pre-rinsing to activate the formation of the phosphate layer and after-treatment with rinsing solutions based on Cr (VI) and / or Cr (III) etc. or with impregnating agents such as rust protection oils, waxes and synthetic resins.
- the stock solution mentioned under 5. was modified by adding NO3, ClO3, Cl, nickel and nitrobenzenesulfonate (NBS) according to the table below.
