Definitions
- the invention relates to the preparation of cleaned metal surfaces, in particular strips of aluminum or aluminum alloys for a subsequent coating with organic coatings, in particular the manufacture of metal goods for architectural applications and for the food packaging sector.
- the metal surfaces are cleaned of oil, dirt and other residues. Any residues of chemicals from this first stage are removed by rinsing with water.
- the clean metal surface is wetted with an aqueous bath solution, which is no longer rinsed off, but is dried in situ on the metal surface and converted there into a solid in the bath components.
- Such coatings can substantially improve the surface quality, in particular with regard to corrosion protection and adhesion of subsequently applied cover layers.
- EP-B-8942 discloses treatment solutions, preferably containing aluminum cans
- DE-C-24 33 704 describes treatment baths to increase paint adhesion and permanent corrosion protection on, inter alia, aluminum, 0.1 to 5 g / 1 polyacrylic acid or its salts or esters and 0.1 to 3.5 g / 1 ammonium fluorozirconate, calculated as ZrÜ2, may contain.
- the pH values of these baths can fluctuate over a wide range. The best results Results are generally obtained when the pH is 6-8.
- US-A-4 992 116 describes treatment baths for the conversion treatment of aluminum with pH values between about 2.5 and 5, which contain at least three components:
- WO 92/07973 teaches a chrome-free treatment process for aluminum, the essential components in acidic aqueous solution 0.01 to about 18 wt .-% H2ZrF and 0.01 to about 10 wt .-% of a 3- (N-C ⁇ _4alkyl-N -2-hydroxyethyl inomethyl) -4-hydroxystyrene polymer used.
- German patent application P 4317217.2 describes a method for pretreating surfaces made of aluminum or its alloys before a second, permanently corrosion-protecting conversion treatment, in which the surfaces are brought into contact with acidic aqueous treatment solutions, the complex fluorides of the elements boron, silicon, titanium, zircon or hafnium individually or in a mixture with one another in concentrations of the fluoro anions totaling between 100 and 4000, preferably 200 to 2000, mg / 1 and having a pH between 0.3 and 3.5, preferably between 1 and 3 .
- the treatment solutions can additionally contain polymers of the type of polyacrylates and / or the reaction products of poly (vinylphenol) with aldehydes and organic hydroxyl-containing amines in concentrations below 500 mg / 1, preferably below 200 mg / 1.
- Phosphoric acid is another optional component of these baths.
- US-A-4136073 claims a chrome-free treatment process for aluminum surfaces, in which the surfaces are treated with acidic (pH 1.2 to 5.5) brings into contact aqueous solutions containing an organic film former and a soluble titanium compound in the weight ratio polymer: titanium between 100: 1 and 1:10.
- the preferred titanium concentration is between 0.01 and 5% by weight.
- the present invention is based on the object of creating a chromium-free “no-rinse” method of the type described at the outset or suitable treatment agents which are suitable for architectural applications and in particular for use in the food packaging sector.
- the requirements typical of food applications such as, for example, the sterilization of the packaging made from the treated material and the avoidance of peeling off the coating when opening cans ("feathering") must be met.
- the method according to the invention is intended to produce a uniform, visually appealing finish layer on the metal surface, which, for example in the subsequent overcoats with clear lacquers, meets the aesthetic requirements which are particularly desired in the field of food packaging.
- the invention accordingly relates to a process for producing chromium-free conversion layers on surfaces of aluminum and its alloys in the no-rinse process by treatment with aqueous solutions with a pH between 1 and 3.5, the titanium and / or zirconium as well as organic film formers, characterized in that the surfaces are brought into contact with solutions which
- the treatment solutions preferably contain
- Such treatment solutions best meet the different requirements for the behavior of the coating which contain both Ti (IV) and Zr (IV), a weight ratio Ti: Zr in the range 3: 1 to 1: 3 being particularly preferred.
- the pH of the solutions should preferably be between 1.5 and 2.5.
- the fluoride is preferably used as a complex-bound fluoride, for example as TiFö 2 "or ZrFö 2- .
- the organic film former is expediently a synthetic polymer with a sufficient content of free carboxyl groups which ensure its water solubility or homogeneous dispersibility in water in the pH range according to the process.
- Particularly suitable are polymers of acrylic acid and / or methacrylic acid, which may also contain limited amounts of copolymers and the corresponding esters, nitriles and / or amides.
- Preferred organic film formers are clearly soluble polyacrylic acids, which retain their clear solubility, particularly in the pH range of the aqueous treatment baths. In general, these are polyacrylic acids of a molecular weight which is not too high, for example those with molecular weights from 20,000 to about 150,000, preferably from 40,000 to about 100,000.
- a conventionally cleaned and rinsed metal surface is rinsed with the aqueous treatment solution in any manner desired after rinsing with demineralized water and drying and / or after squeezing off the water film in such a way that expediently per square meter of the surface about 3 to 10 ml, preferably about 4 to 8 ml, of the aqueous treatment solution are applied.
- the aqueous treatment solutions according to the invention can be applied to the cleaned metal strips can be applied in any type of application which is suitable for producing a uniformly defined liquid film in the specified quantity ranges on the metal surface.
- the roller application method with two or three rollers (“chemcoater”) has proven successful, but also wetting of the strip by spraying or dipping with subsequent squeezing off of the excess liquid film by means of, for example, plastic-coated leveling rollers or adjustable air doctor blades can be used.
- the temperature of the treatment solution can be between 15 and 50 ° C. The temperature is preferably chosen between 20 and 35 ° C.
- the applied liquid film is allowed to act on the metal surface for a reaction time of about 1 to 40 seconds, whereupon the film is dried and thermally treated at an elevated temperature.
- a deformable water-insoluble solid Im remains on the metal surface with a mass per unit area of approximately 50 to 350 mg / m 2 , preferably approximately 100 to 250 mg / m 2 .
- the drying and / or the thermal treatment of the applied liquid film or the chemicals applied with it can take place in the temperature range from about 50 to 125 ° C., the range between 50 and 80 ° C. being preferred.
- Both acidic and alkaline cleaners are suitable for the cleaning pretreatment of the metal surfaces to be wetted according to the invention.
- the layers obtained with the aqueous treatment solution according to the invention provide a uniform finish without discoloration of the base material.
- suitable organic coatings applied below they meet the requirements for the food packaging sector.
- the invention further relates to the aqueous concentrates of the treatment solutions suitable for this process.
- the concentrates are advantageously adjusted so that they are diluted with 2 to 50 parts by weight of water per part by weight of concentrate for use in the process according to the invention. Examples
- surfactant-containing alkaline or acidic cleaning agents eg RID0LINE R C 72 or RID0LINE R 124/120 E
- a treatment temperature 50-65 ° C and treatment times of 8-20 s.
