Definitions
- the invention relates to a method for refining the optical Appearance of the surface one from another Material as copper existing object, in which the Surface of the object with a layer of an oxidizable Ordering agent containing copper components becomes.
- JP-A-1-31981 is a surface treatment respectively Coating objects known per se are already made from a copper material. These items get a superficial coating that already contains oxidized copper components. This will only a pre-oxidation of the surface of a copper material achieved.
- the known method is on objects made of a material other than copper cannot be used.
- the invention has for its object to provide a method with any surface, especially roofing areas made of modern materials, the look of a Can get copper surface, especially including the Signs of patination.
- the object is achieved according to the invention by a method of the type mentioned at the beginning, which is characterized by that the item using one of the copper parts binding binder due to their Thickness from 100 to 150 micrometers of the weather and its erosion and oxidation effects can be exposed to a coating.
- any conventional paint application methods are used can, for example painting, rolling, spraying and so on.
- the surface to be treated i.e. the surface, can be practically arbitrary.
- the application medium contains copper components that cause oxidation exposed, that is, they form a patina, i.e. verdigris apply, and with advantage a completely natural patina, since this is actually copper.
- the treated surface therefore receives a completely natural, appearance corresponding to a normal copper surface.
- the method according to the invention has the advantage that as a substructure functional, inexpensive building materials can be used whose appearance doesn't matter, because afterwards a surface finish takes place anyway. An erosion of the application agent from the surface would only have the consequence that the Order must be touched up without the substructure is damaged in any way, so in particular a roof is tight and weatherproof despite copper erosion remains.
- a binder of the application agent and the Copper components also separated in a two-step process can be applied from each other. First of all, the binder even spread, rolled up or in another Way to be applied. Then the copper parts are dusted on, for example using a fine sieve-dust method, and preferably until one is reached almost dry surface.
- the thickness of the binder layer can be, for example, 100 to 150 microns.
- the binder can then be cured, for example be cured hot, and if necessary subsequently be cooled. After that, the excess copper content be removed, for example suctioned off will. Then the copper parts either patinate through the weather by itself over time or it can Patination can also be accelerated by a special Patination substance, for example a patination solution, is applied.
- the binder, possibly the extender, and the total amount of copper as a homogeneous mixture, with supercritical pigment volume concentration on the with substrate surface provided with a primer be, or the binder, possibly the extender, and a Part of the amount of copper used as a homogeneous mixture with subcritical pigment volume concentration (PVC) on the Substrate are applied and only then further copper portions are applied, for example using a fine sieve-dust method, preferably until it is reached an almost dry surface and a supercritical PVC.
- the two-step process has the advantage of being a primer of the substrate is not necessary since the applied coating has a subcritical PVC. This will ensures good adhesion of the coating to the substrate. Since also in the area of the coating surface the copper content is extremely high (highly supercritical PVC), good and quick patination is possible.
- the layer thickness of the coating is in both cases about 100 to 150 microns.
- the upper copper parts of the coating either through atmospheric exposure over time patinate or it can be patinated with special patination aids, for example patination solutions.
- patination aids for example patination solutions.
- a particular advantage of the method according to the invention is that a light and quick patination in the Mechanical production is possible and therefore evenly patinated and thus optically enhanced articles be available.
- the application procedure according to the first Alternative is suitable for molded articles with strong structured surfaces.
- the application method according to the second alternative is suitable for the coating of flat substrates (roofing materials of all kinds) by machine.
- the ratio of the proportions of copper to the proportions of binder gives certain properties of the application medium in front. If the copper content is too high, the strength may decrease of the order, the copper content is too low, so may not have the desired copper appearance reached. In the method according to the invention, the Copper content only slightly below the critical one Pigment volume concentration.
- the copper components can be integrated in the binder, or, as already mentioned, in a two-stage process be applied. Subsequent application has additional Advantages. With the underground comes essentially only binder in contact, which is a particularly good bond strength guaranteed.
- the outer surface of the order will mainly formed by copper parts, so that the outer Appearance is particularly coppery and large proportions the surface of the copper parts of the oxidation for patina formation are exposed.
- PVK pigment volume concentration to a high degree
- the surface to be patinated is a supercritical one PVC to aim for quick copper reaction.
- binders come as binders into consideration, especially synthetic resin binders. It can basically be inorganic or organic solvent-free or solvent-based in order to be solvent-dilutable or water-dilutable binders. In particular, a suitable one can be used for a respective surface Binder can be selected.
- An extender can also be added to the binder. which is preferably well homogenized with the binder.
- Suitable binders are: setting agents Mortar and sulfates, so-called asbestos cements, sodium and potassium water glass, Organosilicates, polyurethanes, epoxy systems, Chlorinated rubber, oxidative drying resins, unsaturated polyesters, Thermoplastics, polyisocyanate, polyether polyol.
- Fillers or extenders can be considered, for example: Quartz flour, kaolin, talc, natural aluminum and magnesium silicate hydroxides.
- Binder epoxy resin reaction lacquer containing solvents - Reacts moisture-curing at low temperatures lK-PUR lacquer, solvent-based.
- Epoxy resin system solvent-based, cold curing.
