Definitions
- the invention relates to a method for refining the optical appearance of the surface of an object, preferably a roof.
- the invention further relates to a means for application to the surface of an object, preferably for carrying out the aforementioned method.
- a copper roof is often chosen as the roof, particularly for old buildings, such as churches or similar buildings.
- copper sheets of approximately 0.6 mm thickness are laid on a wooden substructure on the roof surfaces and fixed with nails. This involves a copper requirement of around 5 to 6 kg per square meter of roof.
- Private builders may also have something special Appearance of a copper roof, especially because of the particularly beautiful appearance of the greenish patina of such a copper roof, the desire to choose a copper roof for your private house. However, they often shy away from this because of the high costs and give preference to tried and tested, customary, cheaper building materials for roofing.
- the invention has for its object to provide a method and a corresponding means with which any surface, in particular roofing surfaces made of modern materials, can get the appearance of a copper surface, especially including the patination.
- the agent according to the invention should be as inexpensive and easy to apply and, particularly with regard to use in roofing, also be weatherproof.
- the object is achieved according to the invention by a method of the type mentioned at the outset, which is characterized in that the surface is provided with a layer of an application agent containing copper components exposed to oxidation.
- an application agent is thus advantageously applied in a simple manner to the surface of any object, for example a roof, facade or wall cladding, a sculpture, an obelisk, a column or the like, any conventional paint application methods being able to be used, for example painting, rolling, spraying and so on.
- the surface to be treated ie the surface, can be practically arbitrary.
- the application agent according to the invention contains copper components which are exposed to oxidation, i.e. which form a patina, that is to say verdigris, and advantageously a completely natural patina, since it is actually copper.
- the treated surface therefore has a completely natural appearance, corresponding to a normal copper surface.
- the method according to the invention has the advantage that functional, inexpensive building materials can be used as the substructure, the appearance of which does not matter, since a surface finishing takes place anyway.
- An erosion of the application agent from the surface would only have the consequence that the application may have to be improved at the appropriate point without the substructure being damaged in any way, so that, in particular, a roof remains tight and weatherproof despite copper erosion.
- a further development of the method according to the invention provides that a binder of the application agent and the copper components can also be applied separately from one another in a two-stage procedure.
- the binder itself can be spread, rolled up or applied in some other way.
- the copper fractions can then be dusted on, for example using a fine-sieve fly-dust method, and preferably until an almost dry surface is reached.
- the thickness of the binder layer can be, for example, 100 to 150 micrometers.
- the binder can then be cured, for example cured hot, and then optionally cooled.
- the excess copper components can then be removed, for example, by suction. Subsequently, the copper portions either patinate themselves over time due to the weather or patination can also be accelerated by applying a special patination substance, for example a patination solution.
- a particular advantage of the method according to the invention is that the copper portions can also be advantageously pre-patinated so that the embellished surface immediately has a relatively uniform patination.
- the binder, possibly the extender, and the entire amount of copper as a homogeneous mixture with a supercritical pigment volume concentration can be applied to the substrate surface provided with a primer, or the binder, possibly the extender, and part of the used
- the amount of copper is applied to the substrate as a homogeneous mixture with a subcritical pigment volume concentration (PVC) and only then are further copper portions applied, for example using a fine sieve-dust method, preferably until an almost dry surface and a supercritical PVC are reached.
- PVC subcritical pigment volume concentration
- the two-stage process has the advantage that priming of the substrate is not necessary, since the applied coating has a subcritical PVC. This ensures good adhesion of the coating to the substrate. In addition, since the copper content in the area of the coating surface is extremely high (highly supercritical PVC), good and quick patination is possible.
- the layer thickness of the coating should be about 100 to 150 micrometers in both cases.
- excess copper particles from the process of the second alternative can be removed, for example by suction, and returned to the process.
- the upper copper portions of the coating can either patinate in the course of time due to atmospheric action or they can be patinated using special patination aids, for example patination solutions.
- a particular advantage of the method according to the invention is that an easy and quick patination is possible in the context of machine production and thus evenly patinated and thus optically upgraded items are available.
- the application method according to the first alternative is suitable for moldings with strongly 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 proportion ratio of the copper proportions to the binder proportions specifies certain properties of the application agent. If the copper content is too high, the strength of the application may decrease; if the copper content is too low, the desired copper appearance may not be achieved. In the method according to the invention, the copper content can be only slightly below the critical pigment volume concentration.
- the copper parts can be incorporated in the binder or, as already mentioned, applied subsequently using the two-step process. Subsequent application has additional advantages. Essentially, only the binder comes into contact with the substrate, which guarantees particularly good adhesive strength.
- the outer surface of the order is mainly formed by copper components, so that the external appearance is particularly copper-like and large parts of the surface of the copper components are exposed to oxidation to form patina.
- the application agent according to the invention is particularly characterized by copper components exposed to the oxidation. These Copper components can also consist of one or more copper compounds.
- the application medium preferably additionally has a binder in which the copper fractions can be incorporated, wherein in a preferred embodiment the binder can have a sponge structure which ensures special embedding of the copper fractions.
- the pigment-volume concentration (PVC) in the individual zones of the coating is largely responsible for the chemical and mechanical properties of the coating (patinability, erosion resistance, adhesive strength on the substrate).
- a subcritical PVC, for good adhesion, but a supercritical PVC on the surface to be patinated, is to be aimed for in the boundary area substrate surface coating for the quick reaction of the copper.
- the coating according to the invention is characterized by the easily patinated copper content.
- These copper components can also consist of copper compounds such as oxides or salts.
- the coating system in the forms described, preferably has a good fixation of the copper articles and also the corroded (patinated) copper fractions, particularly in the area of the critical and supercritical PVC, due to the sponge-like structure of the binder, which considerably reduces mechanical abrasion due to weathering.
- binders come as binders into consideration, especially synthetic resin binders. In principle, they can be inorganic or organic, solvent-free or solvent-containing, solvent-dilutable or water-dilutable binders. In particular, a suitable binder can be selected for a respective substrate.
- An extender can also be added to the binder, which is preferably well homogenized with the binder.

Abstract
Description
Die Erfindung betrifft ein Verfahren zur Veredelung des optischen Erscheinungsbildes der Oberfläche eines Gegenstandes, vorzugsweise einer Bedachung.The invention relates to a method for refining the optical appearance of the surface of an object, preferably a roof.
Weiter betrifft die Erfindung ein Mittel zum Auftragen auf die Oberfläche eines Gegenstandes, vorzugsweise zur Durchführung des vorgenannten Verfahrens.The invention further relates to a means for application to the surface of an object, preferably for carrying out the aforementioned method.
Insbesondere bei alten Bauwerken, beispielsweise bei Kirchen oder ähnlichen Gebäuden, wird oftmals ein Kupferdach als Bedachung gewählt. Bei derartigen Kupferdächern werden auf den Dachflächen Kupferbleche von ca. 0,6 mm Stärke auf einem Holzunterbau verlegt und mit Nägeln fixiert. Dabei fällt ein Kupferbedarf von etwa 5 bis 6 kg pro Quadratmeter Dach an.A copper roof is often chosen as the roof, particularly for old buildings, such as churches or similar buildings. In such copper roofs, copper sheets of approximately 0.6 mm thickness are laid on a wooden substructure on the roof surfaces and fixed with nails. This involves a copper requirement of around 5 to 6 kg per square meter of roof.
Derartige Dächer sind daher sowohl vom Materialaufwand, als auch vom Arbeitsaufwand sehr kostenaufwendig. Auch können beispielsweise im Bereich der Nägel Lokalelemente auftreten, die ebenso wie eventuelle andere Korrosionen, zu Löchern in den Kupferblechen, und damit zur Undichtigkeit des Daches führen, so daß ein solches Kupferdach, wiederum mit einem hohen Kostenaufwand, unter Umständen relativ häufig ausgebessert werden muß.Such roofs are therefore very expensive both in terms of materials and labor. Local elements can also occur, for example, in the area of the nails, which, like any other corrosion, lead to holes in the copper sheets, and thus to the roof leaking, so that such a copper roof, again at high cost, may have to be repaired relatively frequently .
Auch private Bauherren haben eventuell wegen des besonderen Aussehens eines Kupferdaches, insbesondere wegen des besonders schönen Aussehens der grünlichen Patina eines solchen Kupferdaches, den Wunsch, auch für ihr Privathaus ein Kupferdach zu wählen. Hiervor scheuen sie jedoch häufig wegen der hohen Kosten zurück und geben erprobten und üblichen, kostengünstigeren Baumaterialien für die Bedachung den Vorzug.Private builders may also have something special Appearance of a copper roof, especially because of the particularly beautiful appearance of the greenish patina of such a copper roof, the desire to choose a copper roof for your private house. However, they often shy away from this because of the high costs and give preference to tried and tested, customary, cheaper building materials for roofing.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und ein entsprechendes Mittel anzugeben, mit dem beliebige Oberflächen, insbesondere auch Bedachungsflächen aus modernen Materialien, das Aussehen einer Kupferfläche erhalten können, insbesondere einschließlich der Patinierungserscheinungen. Dabei soll das erfindungsgemäße Mittel möglichst kostengünstig und einfach anzubringen sein und, gerade im Hinblick auf die Verwendung bei Bedachungen, auch witterungsbeständig sein.The invention has for its object to provide a method and a corresponding means with which any surface, in particular roofing surfaces made of modern materials, can get the appearance of a copper surface, especially including the patination. The agent according to the invention should be as inexpensive and easy to apply and, particularly with regard to use in roofing, also be weatherproof.
Die Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren der eingangs genannten Gattung welches sich dadurch auszeichnet, daß die Oberfläche mit einer Lage eines der Oxidation ausgesetzte Kupferanteile enthaltenden Auftragsmittels versehen wird.The object is achieved according to the invention by a method of the type mentioned at the outset, which is characterized in that the surface is provided with a layer of an application agent containing copper components exposed to oxidation.
Bei dem erfindungsgemäßen Verfahren wird somit mit Vorteil in einfacher Weise auf die Oberfläche eines beliebigen Gegenstandes, beispielsweise einer Bedachung, einer Fassaden- oder Wandverkleidung, einer Skulptur, eines Obelisks, einer Säule oder dergleichen ein Auftragsmittel aufgetragen, wobei beliebige herkömmliche Farbauftragungsmethoden angewandt werden können, also beispielsweise Streichen, Rollen, Spritzen und so weiter. Die zu behandelnde Oberfläche, d.h. der Untergrund, kann praktisch beliebig sein.In the method according to the invention, an application agent is thus advantageously applied in a simple manner to the surface of any object, for example a roof, facade or wall cladding, a sculpture, an obelisk, a column or the like, any conventional paint application methods being able to be used, for example painting, rolling, spraying and so on. The surface to be treated, ie the surface, can be practically arbitrary.
Das erfindungsgemäße Auftragsmittel enthält Kupferanteile, die der Oxidation ausgesetzt sind, d.h. die eine Patina bilden, also Grünspan ansetzen, und zwar mit Vorteil eine ganz natürliche Patina, da es sich hier tatsächlich um Kupferanteile handelt. Die behandelte Oberfläche erhält daher ein völlig natürliches, einer normalen Kupferoberfläche entsprechendes Erscheinungsbild.The application agent according to the invention contains copper components which are exposed to oxidation, i.e. which form a patina, that is to say verdigris, and advantageously a completely natural patina, since it is actually copper. The treated surface therefore has a completely natural appearance, corresponding to a normal copper surface.
Damit wird mit dem erfindungsgemäßen Auftragsmittel ein anderer Weg beschritten, als bei herkömmlichen Bronzeanstrichen, mit denen lediglich der entsprechende Metallefekt nachgeahmt wird. Vielmehr wird mit dem erfindungsgemäßen Auftragsmittel in einfacher und kostengünstiger Weise eine Verkupferung erreicht, die ansonsten allenfalls durch eine umständliche und kostenaufwendige Elektrolyse möglich wäre, also ein Verfahren, daß höchstens bei Skulpturen rentabel wäre.This means that the application agent according to the invention takes a different route than conventional bronze paints, with which only the corresponding metallic effect is imitated. Rather, with the application agent according to the invention, coppering is achieved in a simple and cost-effective manner, which would otherwise otherwise only be possible through complicated and costly electrolysis, that is to say a process that would be profitable at most for sculptures.
Desweiteren hat das erfindungsgemäße Verfahren den Vorteil, daß als Unterbau funktionelle, kostengünstige Baumaterialien verwendet werden können, deren Aussehen keine Rolle spielt, da anschließend ohnehin eine Oberflächenveredelung erfolgt. Eine Erosion des Auftragsmittels von der Oberfläche würde nur zur Folge haben, daß eventuell an entsprechender Stelle der Auftrag nachgebessert werden muß, ohne daß dadurch der Unterbau in irgendeiner Weise beschädigt wird, so daß insbesondere eine Bedachung trotz einer Kupfererosion dicht und witterungsbeständig bleibt.Furthermore, the method according to the invention has the advantage that functional, inexpensive building materials can be used as the substructure, the appearance of which does not matter, since a surface finishing takes place anyway. An erosion of the application agent from the surface would only have the consequence that the application may have to be improved at the appropriate point without the substructure being damaged in any way, so that, in particular, a roof remains tight and weatherproof despite copper erosion.
Eine nächste Weiterbildung des erfindungsgemäßen Verfahrens sieht vor, daß ein Bindemittel des Auftragsmittels und die Kupferanteile auch in einem Zwei-Stufen-Vorgehen getrennt voneinander aufgetragen werden können. Zunächst kann das Bindemittel selbst aufgestrichen, aufgerollt oder in anderer Weise aufgetragen werden. Danach können die Kupferanteile aufgestäubt werden, beispielsweise über ein Feinsieb-Flugstaubverfahren, und zwar vorzugsweise bis zum Erreichen einer fast trockenen Oberfläche. Die Dicke der Bindemittelschicht kann beispielsweise 100 bis 150 Mikrometer betragen.A further development of the method according to the invention provides that a binder of the application agent and the copper components can also be applied separately from one another in a two-stage procedure. First, the binder itself can be spread, rolled up or applied in some other way. The copper fractions can then be dusted on, for example using a fine-sieve fly-dust method, and preferably until an almost dry surface is reached. The thickness of the binder layer can be, for example, 100 to 150 micrometers.
Danach kann das Bindemittel ausgehärtet werden, beispielsweise heiß ausgehärtet werden, und gegebenenfalls anschließend abgekühlt werden. Danach können die überschüssigen Kupferanteile abgetragen werden, beispielsweise abgesaugt werden. Anschließend patinieren die Kupferanteile entweder durch die Witterung von selbst im Lauf der Zeit oder es kann auch eine Patinierung beschleunigt werden, indem eine spezielle Patinierungssubstanz, beispielsweise eine Patinierlösung, aufgetragen wird.The binder can then be cured, for example cured hot, and then optionally cooled. The excess copper components can then be removed, for example, by suction. Subsequently, the copper portions either patinate themselves over time due to the weather or patination can also be accelerated by applying a special patination substance, for example a patination solution.
Zudem besteht ein besonderer Vorteil des erfindungsgemäßen Verfahrens darin, daß die Kupferanteile auch mit Vorteil vorpatiniert werden können, so daß die verschönerte Oberfläche sofort eine relativ gleichmäßige Patinierung aufweist.In addition, a particular advantage of the method according to the invention is that the copper portions can also be advantageously pre-patinated so that the embellished surface immediately has a relatively uniform patination.
Insgesamt kann also entweder das Bindemittel, evtl. der Extender, und die gesamte Kupfermenge als homogenes Gemisch, mit überkritischer Pigment-Volumen-Konzentration auf die mit einem Haftgrund versehene Substratoberfläche appliziert werden, oder das Bindemittel, evtl. der Extender, und ein Teil der verwendeten Kupfermenge als homogenens Gemisch mit unterkritischer Pigment-Volumen-Konzentration (PVK) auf das Substrat appliziert werden und erst danach weitere Kupferanteile aufgebracht werden, beispielsweise über ein Feinsieb-Flugstaubverfahren, und zwar vorzugsweise bis zum Erreichen einer fast trockenen Oberfläche und einer überkritischen PVK.Overall, either the binder, possibly the extender, and the entire amount of copper as a homogeneous mixture with a supercritical pigment volume concentration can be applied to the substrate surface provided with a primer, or the binder, possibly the extender, and part of the used The amount of copper is applied to the substrate as a homogeneous mixture with a subcritical pigment volume concentration (PVC) and only then are further copper portions applied, for example using a fine sieve-dust method, preferably until an almost dry surface and a supercritical PVC are reached.
Das Zwei-Stufen-Verfahren hat den Vorteil, daß eine Grundierung des Substrates nicht nötig ist, da die aufgebrachte Beschichtung eine unterkritische PVK aufweist. Hierdurch wird eine gute Haftung der Beschichtung auf dem Substrat gewährleistet. Da außerdem im Bereich der Beschichtungsoberfläche der Kupferanteil extrem hoch ist (stark überkritische PVK), ist eine gute und schnelle Patinierung möglich.The two-stage process has the advantage that priming of the substrate is not necessary, since the applied coating has a subcritical PVC. This ensures good adhesion of the coating to the substrate. In addition, since the copper content in the area of the coating surface is extremely high (highly supercritical PVC), good and quick patination is possible.
Die Schichtstärke der Beschichtung sollte in beiden Fällen etwa 100 bis 150 Mikrometer betragen.The layer thickness of the coating should be about 100 to 150 micrometers in both cases.
Nach dem Aushärten des Bindemittels (physikalisch trocknend, oxidativ, kalt oder heiß härtend) können evtl. überschüssige Kupferpartikel des Verfahrens der zweiten Alternative abgetragen werden, beispielsweise durch Absaugen, in den Prozeß zurückgeführt werden.After the binder has hardened (physically drying, oxidative, cold or hot-curing), excess copper particles from the process of the second alternative can be removed, for example by suction, and returned to the process.
Anschließend können die oberen Kupferanteile der Beschichtung entweder durch atmosphärische Einwirkukng im Laufe der Zeit patinieren oder es kann eine Patinierung durch spezielle Patinierhilfsmittel, beispielsweise Patinierlösungen, erfolgen. Ein besonderer Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß eine leichte und schnelle Patinierung im Rahmen einer maschinellen Fertigung möglich ist und somit gleichmäßig patinierte und damit optisch aufgewertete Artikel zur Verfügung stehen. Das Applikationsverfahren gemäß erster Alternative eignet sich für Formkörper mit stark strukturierten Oberflächen.Subsequently, the upper copper portions of the coating can either patinate in the course of time due to atmospheric action or they can be patinated using special patination aids, for example patination solutions. A particular advantage of the method according to the invention is that an easy and quick patination is possible in the context of machine production and thus evenly patinated and thus optically upgraded items are available. The application method according to the first alternative is suitable for moldings with strongly structured surfaces.
Das Applikationsverfahren gemäß zweiter Alternative eignet sich für die Beschichtung flächiger Substrate (Bedachungsmaterialien aller Art) auf maschinellem Wege.The application method according to the second alternative is suitable for the coating of flat substrates (roofing materials of all kinds) by machine.
Das Anteilsverhältnis der Kupferanteile zu den Bindemittelanteilen gibt bestimmte Eigenschaften des Auftragsmittels vor. Ist der Kupferanteil zu hoch, so nimmt eventuell die Festigkeit des Auftrags ab, ist der Kupferanteil zu niedrig, so wird eventuell nicht das gewünschte Kupfererscheinungsbild erreicht. Bei dem erfindungsgemäßen Verfahren kann der Kupferanteil durchaus nur etwa knapp unterhalb der kritischen Pigment-Volumen-Konzentration liegen.The proportion ratio of the copper proportions to the binder proportions specifies certain properties of the application agent. If the copper content is too high, the strength of the application may decrease; if the copper content is too low, the desired copper appearance may not be achieved. In the method according to the invention, the copper content can be only slightly below the critical pigment volume concentration.
Die Kukpferanteile können in das Bindemittel eingebunden sein, oder wie bereits erwähnt, im Zwei-Sufen-Verfahren nachträglich aufgetragen werden. Das nachträgliche Auftragen hat zusätzliche Vorteile. Mit dem Untergrund kommt im wesentlichen nur Bindemittel in Kontakt, was eine besonders gute Haftfestigkeit garantiert. Die Außenfläche des Auftrages wird hauptsächlich von Kupferanteilen gebildet, so daß das äußere Erscheinungsbild besonders kupfermäßig ist und große Anteile der Oberfläche der Kupferanteile der Oxidation zur Patinabildung ausgesetzt sind.The copper parts can be incorporated in the binder or, as already mentioned, applied subsequently using the two-step process. Subsequent application has additional advantages. Essentially, only the binder comes into contact with the substrate, which guarantees particularly good adhesive strength. The outer surface of the order is mainly formed by copper components, so that the external appearance is particularly copper-like and large parts of the surface of the copper components are exposed to oxidation to form patina.
Das erfindungsgemäße Auftragsmittel zeichnet sich insbesondere aus, durch der Oxidation ausgesetzte Kupferanteile. Diese Kupferanteile können auch aus einer oder mehreren Kupferverbindungen bestehen.The application agent according to the invention is particularly characterized by copper components exposed to the oxidation. These Copper components can also consist of one or more copper compounds.
Vorzugsweise weist das Auftragsmittel zusätzlich ein Bindemittel auf, in das die Kupferanteile eingebunden sein können, wobei das Bindemittel bei einer bevorzugten Ausbildung eine Schwammstruktur aufweisen kann, die für eine besondere Einbettung der Kupfteranteile sorgt.The application medium preferably additionally has a binder in which the copper fractions can be incorporated, wherein in a preferred embodiment the binder can have a sponge structure which ensures special embedding of the copper fractions.
Für die chemischen und mechanischen Eigenschaften der Beschichtung (Patinierbarkeit, Erosionsfestigkeit, Haftfestigkeit auf dem Substrat) ist in hohem Maße die Pigment-Volumen-Konzentration (PVK) in den einzelnen Zonen der Beschichtung verantwortlich. Im Grenzbereich Substratoberfläche-Beschichtung ist eine unterkritische PVK, für eine gute Haftung, an der zu patinierenden Oberfläche jedoch eine überkritische PVK, zur schnellen Reaktion des Kupfers anzustreben.The pigment-volume concentration (PVC) in the individual zones of the coating is largely responsible for the chemical and mechanical properties of the coating (patinability, erosion resistance, adhesive strength on the substrate). A subcritical PVC, for good adhesion, but a supercritical PVC on the surface to be patinated, is to be aimed for in the boundary area substrate surface coating for the quick reaction of the copper.
Die erfindungsgemäße Beschichtung zeichnet sich durch die leicht patinierbaren Kupferanteile aus. Diese Kupferanteile können auch aus Kupferverbindungen wie Oxiden oder Salzen bestehen .The coating according to the invention is characterized by the easily patinated copper content. These copper components can also consist of copper compounds such as oxides or salts.
Vorzugsweise weist das Beschichtungssystem, in den beschriebenen Formen, aufgrund der schwammartigen Struktur des Bindemittels, vor allem im Bereich der kritischen und überkritischen PVK eine gute Fixierung der Kupferartikel als auch der korrodierten (patinierten) Kupferanteile auf, was einen mechanischen Abtrag durch Witterungseinwirkungen erheblich reduziert.The coating system, in the forms described, preferably has a good fixation of the copper articles and also the corroded (patinated) copper fractions, particularly in the area of the critical and supercritical PVC, due to the sponge-like structure of the binder, which considerably reduces mechanical abrasion due to weathering.
Als Bindemittel kommen verschiedenste, handelsübliche Bindemittel in Betracht, insbesondere Kunstharz-Bindemittel. Es kann sich grundsätzlich um anorganische oder organische, um lösungsmittelfreie oder lösungsmittelhaltige, um lösungsmittelverdünnbare oder wasserverdünnbare Bindemittel handeln. Insbesondere kann zu einem jeweiligen Untergrund ein geeignetes Bindemittel gewählt werden.A wide variety of commercially available binders come as binders into consideration, especially synthetic resin binders. In principle, they can be inorganic or organic, solvent-free or solvent-containing, solvent-dilutable or water-dilutable binders. In particular, a suitable binder can be selected for a respective substrate.
Dem Bindemittel kann zudem ein Extender hinzugefügt werden, der mit dem Bindemittel vorzugweise gut homogenisiert ist.An extender can also be added to the binder, which is preferably well homogenized with the binder.
Als Bindemittel kommen beispielsweise in Betracht: Abbinende Mörtel und Sulfate, sog.
