Definitions
- the invention relates to the preparation of cleaned metal surfaces, in particular of strips made of aluminum, aluminum alloys and cold-rolled steel - but also other metal surfaces - for a subsequent coating with organic coatings, with particular attention being paid to the production of metal goods for the food packaging sector.
- the metal surface is cleaned from vl, dirt and other residues in a first stage. 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 on the contrary is dried in situ on the metal surface and converted there into a solid film of the bath components.
- Such coatings can substantially improve the surface quality, in particular with regard to corrosion protection and adhesion of subsequently applied corner layers.
- Treatment solutions containing hexavalent chromium were originally often proposed in the extensive pertinent printed prior art. Because of the toxic nature of this combination, these processes and the rinsing water that they require require elaborate wastewater treatment.
- treatment solutions which contain v-valent chromium and trivalent chromium salts together with film formers are described, for example, in DE-AS 17 69 582 and in DE-OS 29 03 311.
- aicalisate is to be used as the inorganic film former.
- the second reference uses polyacrylic acid as an organic film former. Due to the content of 6-valent chromium in the aqueous building fluids, these materials are not suitable for use in the food sector.
- the present invention is based on the object of creating a “ n o rinse” method of the type described at the outset or suitable treatment agents which do not have the disadvantages known hitherto for materials of this type and in particular for use in the sector of Food packaging are suitable.
- the process according to the invention is intended to produce a glossy, optically 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 relates in a first embodiment to a method for treating metal surfaces, in particular for a subsequent coating with organic-based coating compositions, this method being characterized in that the metal surface is wetted with an aqueous bath solution which contains chromium (III) Ions, fluoride ions and a water-soluble or homogeneously dispersible organic film former.
- the material applied to the metal surface is dried on the metal surface without an intermediate rinsing process and converted into a water-insoluble film by heating.
- the invention relates to the aqueous treatment solutions suitable for this process, which are described in detail below.
- the method according to the invention is suitable for the surface treatment of all metals relevant here, in particular therefore ferrous metals, aluminum or aluminum alloys, zinc and / or magnesium.
- the invention is particularly suitable for the pretreatment of strips made of aluminum or aluminum alloys and cold-rolled steel for their subsequent use in the food packaging sector.
- the bath solution for surface treatment additionally contains phosphate ions.
- Aqueous bac solutions are suitable for the process according to the invention, the active ingredient components of which lie within the following concentration ranges: 0.5 to 10 g / l chromium (III) ions, 0.55 to 11 g / 1 fluoride ions, 0.6 to 12.5 g / l phosphate ions and 0.15 to 5 g / l of the organic film former.
- a conventionally cleaned and rinsed metal surface for example the surface of strips of the aforementioned metals, is squeezed in any way with the aqueous treatment solution after squeezing off the water film in such a way that expediently about 2 to 20 ml per square meter of the area , preferably about 3 to 7 ml of the aqueous treatment solution are applied.
- the content of the aforementioned active constituents of the aqueous treatment solution should continue to be per square meter of the metal surface within the following ranges: 5 to 100 mg of chromium (III) ions, 5.5 to 110 mg of fluoride ions and 6 to 125 mg of phosphate ions, and about 1 , 5 to 35 mg of the organic water-soluble or homogeneously water-dispersible film oil.
- the applied liquid film is allowed to act on the metal surface for a reaction time of about 1 to 10 seconds, whereupon the film is dried and thermally treated at an elevated temperature.
- a deformable water-insoluble solid film remains on the metal surface with a mass per unit area of about 18 to 370 mg / m 2 , preferably of about 50 to 250 mg / m 2, of the metal surface.
- the drying and / or the thermal treatment of the liquid liquid applied or the chemicals applied with it can be carried out in particular in the temperature range from about 50 to 300 ° C.
- Chromium (III) ions and fluorine ions are most easily introduced into the bath using chromium (III) fluoride, although the ratio of chromium (III) ions: fluoride ions is in the range from 1: 2.5 to 3.5 can fluctuate.
- the phosphate content is adjusted by adding phosphates or phosphoric acid with subsequent partial neutralization. It applies that the phosphate content based on 1 mol of chromium (III) ions is preferably in a molar ratio of 0.3 to 3.0.
- 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.
- polymers of acrylic acid and / or methacrylic acid which may also contain limited amounts of copolymers and the corresponding ones May contain esters, nitriles and / or amides.
- Preferred organic film formers are clearly soluble polyacrylic acids, which retain their clear solubility, in particular in the pli range of the aqueous treatment baths - which is usually between about 2 and 3.
- these are polyacrylic acids of a molecular weight which is not too high, for example those with molecular weights of up to about 150,000, preferably up to about 100,000.
- aqueous treatment solutions according to the invention can be applied to the pre-cleaned metal strips in any type of application which is suitable for producing a uniform, defined liquid film in the specified quantity ranges on the metal surface.
- the roller application method with two or three rollers has proven successful, but also wetting of the strip by spraying or dipping with subsequent squeezing off of the excess liquid film by, for example, plastic-coated leveling rollers or adjustable air doctor blades can be used.
- 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, glossy finish without discoloration of the base material.
- suitable organic coatings applied below they meet the requirements for the food packaging sector.
- aluminum strip of the alloy AlMg 5 was first cleaned and degreased by spraying.
- an acidic solution was used with a content of 1 g / l H 2 SO 4 , 0.2 g / l HF and 1 g / l surfactant combination.
- the cleaning was conducted at a temperature-r ature of 60 ° C, 8 seconds, and performed at an injection pressure of 1.5 bar.
- the belt was then rinsed with warm demineralized water and the rinsing water squeezed out.
- a liquid film with a surface area of 5 ml / m 2 was then applied with the solution according to the invention by means of a roller application process, whereby the surface per m 2 is covered with a liquid film containing 25 mg Cr 3+ , 27.5 mg F, 31.3 mg PO 4 and 8.75 mg of polyacrylic acid ("Acrylsol A1" from Röhm & Haas, Philadelphia, USA).
- the water contained in the liquid film was dusted off in a floating dryer with a circulating air temperature of 100 ° C. and a metal object temperature of approx. 50 ° C., and a water-insoluble film of 92.5 mg / m 2 was obtained on the metal surface.
- This tape which was chemically pretreated and lacquered using no-rinse technology, was processed into lids for beverage sockets and, in comparison with lids with conversion layers that were customary to date, was subjected to the tests specific to beverage cans.
- the speeds of rotation of the chemcoater rolls were adjusted so that a liquid film of 8 ml / m 2 of belt surface was applied to a cleaned and water-rinsed aluminum belt at a belt speed of 100 m / minute by means of the application rollers of the chemcoater.
- the tape was wetted with a liquid film, which contains 40 mg Cr 3+ , 44 mg F - , 50 mg PO 4 and 14 mg ' polyacrylic acid 100% strength per m 2 of surface and, after drying, a mass per unit area of 148 mg / m 2 on the aluminum.
- the W was as- se ranteil of the liquid withdrawn from the film by means of hot air dryer and then heated the BAHD to an object temperature of 200 C. After cooling, the film obtained on the tape was wetted with 8 to 10 mg of dioctyl sebacate to improve the sliding property.
- the chemically pretreated aluminum surface thus obtained was coated with varnishes suitable for the food sector and tested for its resistance to filling goods and forming behavior. In all tests, technological values were found which, in comparison to conventional solutions and methods, achieved results which were at least equivalent, and in some cases even better, with the methods according to the invention.
