Definitions
- the invention relates to a method for producing protective layers of dark color tint by pickling rolled flat products made of titanium-zinc alloys for use in construction, the flat products being pickled in an aqueous additive containing mixed acid containing sulfuric acid and nitric acid and after rinsing to form a Protective layer can be passivated.
- the invention also relates to surface products provided with protective layers.
- the alloy disclosed in DE 196 36 370 AI corresponds in their composition the criteria of a "Quality Zinc” catalog from TÜV Arts und reactor GmbH, Institute for Environmental Protection and Energy Technology, Am grau Stein, 51105 Cologne.
- very dark colored surface layers are desired for the construction industry, in order to keep the contrast of the pre-weathered zinc sheets to other building materials used there, for example black slate shingles or roof tiles, low or to provide a strong contrast, especially in the area of roof coverings and facade covers white surfaces.
- the patina consists in particular of zinc carbonate with traces of copper.
- the matt black color obtained allows building materials patinated in this way to be inserted particularly harmoniously into roof coverings with black pans or shingles or, where contrasts are desired, there is a clear gradation in black and white.
- a content of preferably 1.1 to 1.4% by weight of copper in the alloy is sufficient.
- a titanium-zinc alloy is used, the 0.06 to 0.2 wt .-% titanium and max. Contains 0.015 wt .-% aluminum.
- a copper content of over 1.0% by weight up to 2.0% by weight, preferably from 1.1 to 1.3% by weight of Cu, is provided.
- the main part of the alloy consists of zinc, ie, depending on the content of the alloying elements titanium, aluminum and copper, about 97.7 to 98.9% by weight of zinc in the 99.995% purity level.
- a band consisting of a zinc alloy with an increased copper content of 0.8 mm thickness and 600 mm width is degreased by rinsing with an alkaline degreasing solution at a temperature of approx. 60 ° C and a rinsing pressure of approx. 2.5 bar and then with a Water spray sprayed at a temperature of approx. 65 ° C and a pressure of approx. 2.5 bar.
- the belt is brushed in the last rinsing step to support the rinsing process and to roughen the surface.
- the strip is then processed in a pickling line with a pickling bath temperature of 30 ...
- the pickling bath contains a mixed acid of approx. 30 ... 60 g / 1 sulfuric acid and approx. 20 ... 50 g / 1 nitric acid in water. In addition, 25 ... 80 g / 1, preferably approx. 50 g / 1, of zinc ions are present in solution.
- the rate of the pickling reaction is essentially dependent on the free acid content.
- the reduction of nitric acid is the dominant reaction and prevents the development of hydrogen.
- the ratio of the acid contents has a further influence on the pickling result.
- a mixed acid with 2 ... 10% by volume sulfuric acid and 2 ... 10% by volume nitric acid is preferably used, the mixing ratio of sulfuric acid: nitric acid acid is less than or equal to 3: 1, and the free acid content is 25 to 100 g / 1.
- the strip emerging from the pickling line is rinsed as described above.
- Another protective layer is then preferably produced by applying and drying chromate-containing polymer dispersions as follows.
- This application is dried at approx. 80 - 120 ° C.
- the layer thickness of the film produced in the dried state is approximately from 0.4 to 3.0 ⁇ m, preferably 1.5 ⁇ m.
- a polymer dispersion is understood to mean, for example, a mixture of styrene-acrylate, aliphatic polyester and polyurethane.
- a flat product of a titanium-zinc alloy which mainly contains zinc of a high purity level and also a copper content of 1.0 to 2.0% by weight, a titanium content of 0.07 to 0%.
- the latter is preferably covered with a protective layer with a thickness of 0.4-3.0 ⁇ m, which in the exemplary embodiment was obtained after application and drying of a chromate-containing polymer dispersion; the basis weight of the edition is accordingly 5 ... 40 mg / m 2 .
