Definitions
- the invention relates to a process for the passivating rinsing of phosphate layers on metals, in particular steel, galvanized steel, alloy galvanized steel and aluminum, before painting or applying adhesives using chromium-free, zirconium and fluoride-containing aqueous solutions.
- the process of phosphating is widely used industrially to prepare metal surfaces for subsequent painting.
- the phosphate layers generated with this cause u. a. better adhesion of the paint films to the metal, increase the corrosion resistance and inhibit the penetration of paint from damage points in the paint film when exposed to corrosion.
- the protective properties of the phosphate layers are further improved if they are subjected to an aqueous passivating rinse.
- the passivating rinsing agents based on hexavalent and / or trivalent chromium offer good application properties.
- the toxicity of the tri- and especially the hexavalent chromium compounds is disadvantageous.
- US-A-4376000 describes a chrome-free rinse aid based on polyvinylphenol. However, this must be used in a comparatively high concentration, which causes an undesirable wastewater pollution, in particular due to the high oxygen requirement required for the breakdown.
- soluble zirconium compounds for the aftertreatment of conversion layers.
- the rinsing agents contain alkali and ammonium as cations. The presence of alkaline earth metal cations is expressly warned. They are used at a pH of 3 to 8.5. However, these rinsing agents do not reach the quality level of the chrome-containing agents.
- US-A-3895970 describes acidic, aqueous rinsing agents for phosphate layers based on simple or complex fluorides and names chromium zirconium fluoride and zirconium fluoride from the group of zirconium compounds. With the exception of chrome zirconium fluoride, the products mentioned in this patent only meet moderate requirements. Chromium zirconium fluoride, however, has the disadvantage of toxicity already mentioned above.
- the object of the invention is to provide a method for passivating rinsing of phosphate layers on metals before painting or applying adhesives, which does not have the disadvantages of the known methods and is characterized by higher corrosion protection and very good paint and adhesive adhesion and the Does not pollute the environment or only to a very small extent.
- 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 phosphated metal surfaces are rinsed with aqueous solutions, the Al / Zr / F compound with a molar ratio of Al: Zr: F of (0, 15 to 0.67): 1: (5 to 7), the total concentration of Al + Zr + F being 0.1 to 2.0 g / l and the pH adjusted to 3 to 5.
- the phosphated metal surfaces are rinsed with aqueous solutions whose total concentration of Al + Zr + F is 0.2 to 0.8 g / l.
- the method according to the invention is suitable for all types of phosphate layers which can be produced on metals, in particular steel, galvanized and alloy-galvanized steel, aluminized steel, zinc, zinc alloys, aluminum and aluminum alloys.
- metals in particular steel, galvanized and alloy-galvanized steel, aluminized steel, zinc, zinc alloys, aluminum and aluminum alloys.
- These include zinc phosphate, iron phosphate, manganese phosphate, calcium phosphate, magnesium phosphate, nickel phosphate, cobalt phosphate, zinc iron phosphate, zinc manganese phosphate, zinc calcium phosphate and other layer types with two or more divalent cations.
- the metal surfaces are expediently rinsed with water before z. B. by dipping, spraying, flooding or rolling according to the inventive method.
- the rinsing agents used in the process according to the invention can be chemically classified into the group of weakly acidic aluminum fluorozirconates.
- Their manufacture can e.g. B. done so that metallic zirconium or zirconium carbonate is first dissolved in aqueous hydrofluoric acid, complex fluorozirconic acid being formed. Then metallic aluminum or aluminum hydroxide is introduced and dissolved.
- the rinsing agents can also be prepared in other ways.
- the phosphated metal surfaces are rinsed with aqueous solutions which additionally contain at least one of the anions benzoate, caprylate, ethylhexoate, salicylate in a total concentration of 0.05 to 0.5 g / l.
- aqueous solutions which additionally contain at least one of the anions benzoate, caprylate, ethylhexoate, salicylate in a total concentration of 0.05 to 0.5 g / l.
- the anions can be introduced via the corresponding acids or salts.
- the pH of the rinse solutions is preferably adjusted with cations of volatile bases. These include in particular ammonium, ethanolammonium and di- and tri-ethanolammonium.
- the application of the passivating rinse on the phosphated metal surfaces can be done in dipping, flooding, spraying and wetting, e.g. B. done by roller application. Treatment times are between about 1 sec to 2 min.
- the application temperature can range from room temperature to about 80 ° C. Temperatures between 20 and 50 ° C are usually preferred. Demineralized or low-salt water is preferably used for the preparation of the rinse baths. Water with a high salt content is less suitable for bathing.
- a further advantageous embodiment of the invention provides that the phosphated metal surfaces are rinsed with deionized water.
- the method according to the invention is used to prepare the phosphated metal surfaces before painting or applying adhesives. It increases the adhesion of the organic films to the metallic substrate, improves the resistance of the organic films to blistering when exposed to corrosion, and inhibits corrosion penetration from damage points in the film.
- the method has proven to be particularly advantageous in connection with cathodic electrocoating materials, powder coatings, low-solvent high-solid coatings and with coatings in which water is the main solvent.
- Fine-crystalline, uniformly covering phosphate layers with a basis weight of 2.5 to 3 g / m 2 were produced on the three metal substrates.
- the sheets were then rinsed with water and then rinsed passively.
- the passivating rinsing was carried out by spraying at 30 ° C and 1 min treatment time.
- the final treatment was a rinse with deionized water.
- a cathodic electrodeposition primer, a filler and a topcoat were used to paint the sheets. Each layer of paint was baked separately. The total layer thickness was approx. 90 ⁇ m.
- the rinse aid used in the process according to the invention was prepared by diluting 1.6 g of an aqueous concentrate with 0.855% Al + 8.62% Zr + 10.7% F using deionized water. The pH was then brought to 3.5-4.0 with ammonia. The rinse aid then had the following composition: 0.014 g / l Al + 0.14 g / l Zr + 0.17 g / l F + 0.026 g / l NH3.
- the individual sample sheets were tested according to the salt spray test according to DIN 50021 SS (1008 h), the filiform test according to ASTM D 2803 (1008 h) and the General Motors Test Method TM 54-26 with 20 cycles (GM-Scab-Test).
- the paint infiltration was measured in mm.
