Definitions

  • the invention relates to a method and a reaction solution for producing a patina on surfaces of objects made of copper or a copper alloy.
  • patina In the air, a thin green protective layer of basic copper compounds forms on copper surfaces. This is called patina.
  • the formation of natural patina sometimes takes several decades, depending on the environment. Artificial patination, for example by application of soluble copper salts or ammonium salts, serves to imitate this natural patina, which often forms over long periods of time.
  • basic copper compounds are applied as color pigments with organic or inorganic film formers to a copper surface.
  • the US-A-3,497,401 discloses a method and reaction solution for producing a patina on the surface of a copper article.
  • the reaction solution consists of an aqueous solution containing potassium chlorate and copper sulfate.
  • a reaction solution is used to produce a patina on copper objects, which in aqueous solution contains hydrochloric acid, copper carbonate, ammonium chloride, copper acetate, arsenic trioxide and copper nitrate.
  • reaction solutions do not always provide the desired results in terms of layer quality and coloration. Also, their handling and storage is sometimes expensive. They are therefore only of limited suitability for industrial use for factory production of a patina or when used on the construction site. Also, when using some of these reaction solutions on preoxidized or partially patinated copper surfaces, for example for repair of damaged patina, there is a risk of uneven layer formation and staining.
  • the WO 97/35046 describes a process in which an artificial patina is to be produced with the aid of a reaction solution of copper sulfate, sodium thiosulfate and lead (II) acetate.
  • This reaction solution has by their lead component the great disadvantage that it is classified in terms of their health and environmental hazards as critical and it does not meet the requirement of the invention for environmentally friendly use.
  • the invention is therefore based on the object to provide a method for producing a mechanically stable patina on preferably pre-weathered copper surfaces, wherein the patina produced has a reduced copper solubility and as in a natural patina, an interaction with the atmosphere is possible. Furthermore, the invention aims at an improved reaction solution for producing a patina on copper surfaces, which is also easy to handle and storage.
  • a reaction solution consisting of an aqueous solution of copper salts in the form of copper (I) carbonate, copper (II) carbonate, copper (I) chloride, copper (II) sulfate, copper nitrate or mixtures thereof is applied to the surface of a copper article after its purification in a concentration between 0.5% and 50% and salts of inorganic acids in the form of sodium carbonate, potassium carbonate, ammonium carbonate, sodium bicarbonate, potassium bicarbonate, sodium chloride, potassium chloride, ammonium chloride, sodium sulphate, sodium bisulphate, potassium sulphate, potassium bisulphate or mixtures thereof in a concentration between 0, 5% and 50% applied.
  • the thus treated copper object is then exposed to weathering the drying exposed.
  • the patina produced according to the method is mechanically stable and has only a low copper solubility. The time for producing the patina is comparatively low.
  • the generated patina is provided after drying with a transparent protective layer of paint.
  • this is a two-component water-based paint is used, which contains rubber.
  • the paint is colorless.
  • the paint Before application, the paint is applied with hardener.
  • the ratio of hardener to paint is usually 1: 4.
  • the starting time is a maximum of 20 minutes.
  • the finished mixed paint is then preferably applied to the patina with a sprayer.
  • the paint After the drying phase, the paint is cured and can be weathered. Depending on the prevailing ambient conditions (temperature, humidity, etc.), the dry phase can take 15 to 24 hours.
  • a copper article according to the invention is characterized according to claim 2 by its transparent lacquer layer on the patinated surface.
  • An inventive copper article or its patina surface is improved in resistance to external environmental influences and damage.
  • the patinated copper objects can be machined without the patina flaking off.
  • reaction solution consists of an aqueous solution of copper salts and salts of inorganic acids and contains a wetting agent and / or a thickener in a proportion of up to 5%.
  • the reaction solution according to the invention uses the combination of two different principles for patina formation.
  • the reaction solution contains reactive components in the form of salts of inorganic acids, which react with the copper oxides of the patinated surfaces to form basic copper compounds.
  • the speed of this reaction step depends on the weathering conditions.
  • the solution already contains the forming in these reactions copper compounds in the form of copper salts as a kind of color pigments. For this reason, a very good color impression is already achieved immediately after the application. The imitation of the otherwise often only in long periods forming natural patina happens in a short time.
  • the subsequent chemical reaction intensifies the color impression and solidifies the entire patina layer.
  • the best success with the reaction solution according to the invention arises when used on a preoxidized or already partially patinated copper surface. For this reason, the copper articles should receive a corresponding surface pretreatment.
  • the copper surface may be pre-oxidized or pre-patinated at the factory.
  • the copper surface may also have a natural patina caused by natural weathering.
  • An untreated copper surface should be exposed to natural weathering for about two months or more.
  • the treatment can be carried out with the reaction solution according to the invention.
  • a patina layer By applying the reaction solution on a pre-oxidized or already partially patinated copper surface, a patina layer can be produced directly on site or else at the factory. Also, copper surfaces that are not completely patinated green or damaged patina layers obtained when applying the reaction solution according to the invention a uniform patina layer. Depending on the composition of the reaction solution, the color of the patina to be produced can be varied and otherwise adapted to the respective environment.
  • the processing and handling of the reaction solution according to the invention is simple.
  • the order on the copper surfaces can be done for example by means of a brush, roller or a spray device.
  • a storage of the reaction solution is possible over a longer period of several months at room temperature, without aging damage.
  • copper (I) carbonate, copper (II) carbonate, copper (I) chloride, copper (II) chloride, copper (II) sulfate, copper acetate, copper nitrate or mixtures thereof are well suited.
  • the advantageous concentration range is between 5 and 500 g / l.
  • the reactive component used is preferably sodium carbonate, potassium carbonate, ammonium carbonate, sodium bicarbonate, potassium bicarbonate, sodium chloride, potassium chloride, ammonium chloride, sodium sulfate, sodium hydrogensulfate, potassium sulfate, sodium hydrogensulfate, potassium sulfate, potassium hydrogensulfate or mixtures thereof.
  • concentration range of these salts of inorganic acids is preferably between 5 and 500 g / l.
  • the reaction solution according to the invention can be changed in its consistency by the addition of wetting agents or thickeners and be tailored to the particular conditions of use.
  • wetting agents for example surfactants, and / or come Thickeners of known type for use. They are added to the reaction solution to a level of 5%.
  • the reaction solution according to the invention produces a high quality patina from basic copper compounds and is particularly well suited for preoxidized or already partially patinated copper surfaces.
  • the treatment can be done on site or at the factory.
  • the reaction solution is also good for that
  • the reaction solution can be prepared and processed at room temperature. It has been found to be expedient that a patinated surface after treatment with the reaction solution should be protected from rain for at least 48 hours.
  • the patina layer produced in this way can then be coated with a transparent protective layer to avoid damage and to reduce the copper solubility.
  • a transparent protective layer to avoid damage and to reduce the copper solubility.
  • water-vapor-permeable paints are used, which produce an open-pored protective layer and thus allow the natural interaction of the patina surface with the atmosphere.
  • An aqueous solution containing 200 g / l of copper sulfate is first mixed with 200 g / l of sodium carbonate and stirred for one hour at room temperature. Thereafter, 200 g / l of sodium chloride are added and stirred for another hour at room temperature. Subsequently, the solution can be applied directly to the surface to be patinated.
  • a wetting agent for example a surfactant, in a concentration of 50 g / l is added.
  • the solution is thickened with a commercially available thickener in a concentration of 50 g / l.
  • the reaction solution thus prepared can be stored without restriction at room temperature.
  • the copper surface to be patinated has a dark brown copper oxide layer, which in places is already covered with copper salts (patina).
  • the surface is freed from grease and loosely attached dirt before patinating.
  • the removal of loosely adhered dirt particles can be done using water and manual or mechanical means.
  • the surfaces which should not be patinated are masked off. Thereafter, the already prepared ready reaction solution is shaken or stirred and applied.
  • a sprayer has proven particularly suitable for this purpose. Depending on the performance of the sprayer used nozzles between 0.2 mm and 0.6 mm diameter are used. For uniform coating of the surface, spray angles of 60 ° to 90 ° considered advantageous. Care should be taken during treatment to avoid dripping on the surface.
  • the drying process should be as slow and even as possible. This improves the quality of the patina.
  • the protective layer of lacquer can then be applied.
  • a sprayer preferably with nozzles between 0.2 mm and 0.3 mm in diameter, and a spray angle of 90 ° is recommended.
  • a single application of the protective layer is sufficient.
  • the protective layer which can be between 20 minutes and 24 hours depending on weather conditions, the copper object should be protected from precipitation.
