Definitions
- the invention is in the field of cleaning and corrosion protection of tinned steel, in particular food or beverage cans made of this material, so-called tinplate cans, in the process of producing cans between can molding and painting.
- Tin cans are usually made by pre-forming, deep drawing and smoothing. They have a desirable glossy metallic surface, so that they are suitable as attractive packaging after a coating treatment with a clear or opaque organic lacquer or printing on the outer surface.
- the process sequence in the production of tinplate cans usually consists in unwinding the tinplate strip provided with a protective oil layer from the coil, in applying drawing lubricants, in a first preliminary shaping to a cup and in deep drawing and smoothing to form the final shape.
- drawing lubricants such as water or aqueous emulsions which facilitate the deep-drawing process are usually used in the drawing and smoothing process.
- the residues of the protective oiling and the drawing aids as well as any metal abrasion are removed in a cleaning process.
- the containers are passed through one or more water rinsing stages and then in dried in a drying oven. This is followed by a one- or multi-stage painting and decorative printing on the outer surface.
- the metallic surface must be such that the paint has sufficient adhesion and provides reliable protection against corrosion.
- this problem can be solved in the case of untinned steel cans, so-called black tin cans, in that after the actual cleaning step the cans are treated with an aqueous corrosion-protecting solution which contains 10 to 5000 pp aluminum ions, 10 to 200 ppm fluoride ions and up to 1,000 ppm ions contains at least one of the metals titanium, zirconium and / or hafnium and which has a pH of 2 to 5.5.

- concentration ranges are particularly preferred for the individual active ingredients: 150 to 300 ppm complex fluorides of the elements boron, titanium, zirconium and / or hafnium, 300 to 1000 ppm nonionic surfactants 150 to 500 ppm corrosion inhibitor.
- An aluminum salt which is soluble in the specified concentration range is preferably used as the source of the aluminum ions.
- the nitrate and in particular the sulfate are suitable, while the chloride is less preferred for reasons of corrosion technology.
- the cleaning solution is also used as a further active ingredient or auxiliary 200 to 800 ppm contains one or more mono-, di- or tri-basic hydroxycarboxylic acids with 4 to 7 carbon atoms in the molecule, the sum of hydroxyl and carboxyl groups being at least 3.
- the hydroxycarboxylic acid or the hydroxycarboxylic acids are preferably selected from mono- or dibasic hydroxycarboxylic acids with 6 carbon atoms and at least 4 hydroxyl groups. Gluconic acid is particularly preferred.

- a cleaning solution is particularly preferred which contains complex fluorides of boron and of zirconium in a weight ratio between 4: 1 and 1: 1, in particular in a weight ratio between 3: 1 and 1.5: 1.
- Preferred nonionic surfactants are those surfactants or surfactant mixtures which have a cloud point below about 40 to about 45 ° C. This makes it possible to use the cleaning solution at a working temperature between about 50 and about 70 ° C. in spraying, without excessive and disruptive foam formation occurring.
- Suitable surfactants are, in particular, ethoxylates and ethoxylate propoxylates of alkanols with about 10 to about 18 carbon atoms.
- the ethoxylates and / or the ethoxylate propoxylates can also be end-capped and can be present, for example, as butyl ethers.
- the ethoxylates preferably carry 4 to 12 ethylene oxide groups, in particular about 6 to 10 ethylene oxide groups
- the ethoxylate propoxalates preferably carry 3 to 7 ethylene oxide groups and 2 to 6 propylene oxide groups, preferably 4 to 6 ethylene oxide groups and 3 to 5 propylene oxide groups.
- a pure compound with a specific carbon chain length can be selected as the alkanol component, but it is economically more attractive to use alkanols of oleochemical or oleochemical (oxoalcohol) origin, in which different alkanols with different carbon chain lengths are present.
- suitable alkanol components are fatty alcohol mixtures with 12 to 14 carbon atoms or oxo alcohols with 12 to 15 carbon atoms.
- a surfactant mixture which contains both alkanol ethoxylates and alkanol ethoxylate propoxylates is particularly preferred, for example in a weight ratio between 1: 3 and 1: 1.
- the corrosion inhibitor or the corrosion inhibitors can be selected, for example, from mono-, di- or triethanolamine, aromatic carboxylic acids, pyridine or pyridine derivatives and diethylthiourea.
- aromatic carboxylic acids in particular come Benzoic acid and its substitution products into consideration. Examples include methylbenzoic acids, nitrobenzoic acids, aminobenzoic acids such as, for example, anthranilic acid or p-aminobenzoic acid, and hydroxybenzoic acids such as, for example, salicylic acid.
- Pyridine or pyrimidine derivatives and diethylthiourea are less preferred for use of the treated doses in the food sector.
- An example of an inhibitor combination which can be used is a mixture of triethanolamine and benzoic acid, for example in a weight ratio between 3: 1 and 1: 3. Triethanolamine can also be used as the only corrosion inhibitor.
- the complex fluorides are used in the form of their acids when preparing the cleaning solution, it may be necessary to add the pH to the desired range between about 3 and about 6, preferably between about 4 and about 5, by adding bases.
- Basic alkali metal compounds such as hydroxides or carbonates are suitable for this.
- ammonia is preferably used to adjust the pH.
- the invention relates to the use of the cleaning solution characterized above for cleaning, for corrosion protection and / or for improving paint adhesion on objects made of tinned steel, in particular for food or beverage cans.
- this method has the advantage of simultaneously cleaning and temporary protection against corrosion in a single treatment step.
- the corrosion protection prevents corrosion of the metal surfaces before painting, which could occur, for example, when the system is down.
- the paint adhesion and the corrosion protection in the painted state are improved, without another after the cleaning stage Treatment level is required.
- the cans are usually rinsed with water, dried at an elevated temperature and then painted.
