Definitions
- the invention relates on the one hand to a copper strip or sheet with a reddish brown to dark brown Covering layer for use in the construction sector.
- the invention is to preferred methods for Production of a brown cover layer on copper existing strip-shaped semifinished product, in particular on rolled strips and sheets for the roof covering and facade cladding, addressed.
- the formation of the brown topcoat can be but under certain atmospheric conditions considerably delay but also speed up so that, as a rule, it takes a relatively long time to wait until a uniform discoloration of the copper surface is reached. Deviations from a uniform Coloring are especially in the initial stages to watch the weathering. On the copper surface often form unevenly at first dark spots and / or streaks. In the further course the weathering by atmospheric influences however, these color differences are becoming noticeable.
- a process for producing uniform Layers of copper (I) oxide on the surface of Copper wire or tape is for example in Chemical Abstracts, Vol. 83, No. 2, July 1975, page 258, abstract No. 32184t mentioned.
- this known Process is the copper oxide layer by an oxidizing Heat treatment at a temperature range formed from 300 to 1000 ° C lying temperature.
- From US-PS 5,282,890 is a method for producing a brown Covering known on a copper strip or sheet, in which by a heat treatment with the treatment parameters ⁇ Treatment temperature 150 ° C to 650 ° C and treatment time 0.1 to 30 Minutes, especially at a treatment temperature between 150 ° C and 350 ° C, preferably about 275 ° C, and a gas atmosphere with a Oxygen content of about 25 vol.% In the treatment furnace and a Treatment time between 0.1 and 30 minutes a dark brown layer is produced from copper oxides on a copper strip.
- the invention is based on the object, on the one hand a copper strip or sheet of the aforementioned To provide kind on the surface a uniform and firm brown cover layer (Brown patina) and that at reduced Solubility of copper ions easy to handle and is to be processed.
- the invention is based on the object Method for producing a brown cover layer on copper existing band-shaped To create semi-finished products.
- the two-layer covering layer consists of a first layer of Cu 2 O adhering to the base metal with a thickness lying in the range of 0.05 to 5 ⁇ m, preferably in the range of 0.1 to 1 ⁇ m, and a second layer of CuO arranged above it Thickness between 1 and 100 nm, preferably with a thickness between 10 and 50 nm.
- Procedure prepared prepatinated Strips or sheets of copper have cover layers, which both have excellent adhesive strength as well as deformation or bending during bending stay, d. H. show no detachment. Even when installing roofing and cladding often inevitable finger marks remain largely on the pre-patinated surface unremarkable.
- the improved adhesion of the cover layer and the even more uniform browning of the prepatinized copper surface can be achieved both by carrying out a second heat treatment under oxidizing conditions to form a CuO layer immediately after the first heat treatment under a mixed gas atmosphere containing defined oxygen.
- the Cu 2 O intermediate layer serves as a bonding agent for the CuO layer.
- the Cu 2 O layer protects the copper sheet from local corrosion, while the CuO layer is responsible for reducing surface corrosion (copper ion solubility) from acid rainwater or other media aggressive to copper.
- a chemical also performs Post-oxidation with an aqueous solution of a alkaline salt alone or in combination with a salt of the inorganic peroxide, organic peroxides and hydrochloric acid Group to the same result.
- a cold rolled and optionally degreased strip of SF copper according to DIN 1787 with a thickness of 0.6 mm and a width of 100 mm (sample 1) was roughened uniformly by means of a rough work roll. The average roughness of the surface of the copper strip was 5 ⁇ m.
- the copper strip was then fed to a laboratory furnace for heat treatment, the operating temperature of which was set at about 480 ° C.
- a controlled gas atmosphere of nitrogen with 2 vol.% Oxygen content was set in the furnace chamber and the copper strip was held for 5 minutes under these conditions.
- the sample 1 was cooled to room temperature in a cooling chamber under inert gas, for example, argon.
- the heat-treated copper tape showed a regular red about 1 micron thick Cu 2 O oxide layer whose crystals had a mean grain size of 0.05 microns.
- the sample 1 was subjected to a second heat treatment at a temperature of 300 ° C. in a mixed gas atmosphere having a higher oxygen content than in the first heat treatment, for example, atmospheric air.
- a second heat treatment a thin dark brown CuO oxide layer having a thickness of about 0.05 ⁇ m (50 nm) grew on the surface of the Cu 2 O intermediate layer.
- CuO layers on copper surfaces are black and consist of tenorite crystals.
- the color values of the two oxide layers add up to the desired reddish brown to dark brown cover layer.
- the thickness of the Cu 2 O intermediate layer is below 0.05 ⁇ m, the proportion of the red color is too small to obtain a dark brown color of the cover layer together with the CuO layer.
- the thickness of the Cu 2 O intermediate layer copper oxide
- the adhesion of this intermediate layer is disadvantageously reduced and the deformability of the layer is no longer guaranteed.
- the best properties in terms of color, adhesion and deformability in the thickness range of the intermediate layer from 0.2 to 0.7 .mu.m.
- sample 2 a copper plate referred to as sample 2 after the first Heat treatment cold worked by 20% and then a second 10 minute heat treatment at 350 ° C to produce a thin dark brown Subjected to CuO layer.
- a copper sheet designated sample 3 was first subjected to a heat treatment for 1.5 minutes at 550 ° C. to form the Cu 2 O intermediate layer and then to form a thin CuO layer at 350 ° C. under oxidizing conditions subjected. After these two heat treatments, sample 3 was cold worked about 10% to increase strength.
- a cold-rolled strip of SF-Cu (hard-rolled state) according to DIN 1787 with a thickness of 0.63 mm and a width of 1000 mm was subjected to recrystallization annealing with simultaneous surface oxidation in a continuous furnace.
- the heat treatment took place above the recrystallization temperature of the copper strip in a controlled gas atmosphere with about 5% oxygen.
- the copper strip was passed through an oxidizing bath heated to about 70 ° C., which consists of a mixture of about 40 g / l of sodium hydroxide solution and about 20 g / l of potassium peroxodisulfate. Subsequently, the copper tape was rinsed with water and dried with hot air.
- the residence times of the copper strip in the continuous furnace and in the chemical oxidation bath can be determined by the time required for soft annealing.
- the copper strip had a uniform, reddish brown to dark brown top layer after these treatment steps.
- the thickness of the Cu 2 O layer was determined to be 0.7 ⁇ m, while the thickness of the CuO layer was about 0.05 ⁇ m.
- the copper strip then rolled semi-hard. Neither here even with additional bending or bending operations showed damage or detachment the topcoat.
