Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen eines Aufbewahrungsmittels und auf ein Aufbewahrungsmittel für Metallteile, insbesondere Silberteile.The invention relates to a method for producing a storage means and to a storage means for metal parts, in particular silver parts.

Bei Gegenständen aus Silber, aber auch aus Kupfer und anderen Buntmetallen, besteht das Problem des sogenannten "Anlaufens", d.h. der Ausbildung einer Korrosionsschicht bei längerer Aufbewahrung an der Luft, insbesondere infolge von Luftverunreinigungen wie beispielsweise Schwefelverbindungen oder dgl.For silver objects, but also copper and other non-ferrous metals, there is the problem of so-called "tarnishing", i. the formation of a corrosion layer with prolonged storage in the air, in particular due to air contaminants such as sulfur compounds or the like.

Es wurden deshalb schon einige Versuche unternommen, Aufbewahrungsmittel für anlaufanfällige Metallteile vorzuschlagen, die ein Anlaufen verhindern oder zumindest stark verlangsamen. So beschreibt beispielsweise die DE-C-198 34 226 ein Anlaufschutzmittel für Metallgegenstände, das innerhalb von geschlossenen Räumen, z.B. in Verpackungen oder Schaukästen, eingesetzt werden kann. Das bekannte Anlaufschutzmittel ist ein Dampfphasen-Korrosionsinhibitor, dessen Wirkprinzip darauf beruht, dass er die sich durch Berührung mit der Atmosphäre sehr schnell bildende inhärente, jedoch meistens nur begrenzt schützende Primäroxydschicht aufrechterhält bzw. verstärkt. Die bekannten Dampfphasen-Korrosionsinhibitoren liegen als Pulver vor und werden in geeigneter Weise in die Verpackung eingebracht. Die Wirksamkeit derartiger Korrosionsinhibitoren steht und fällt jedoch mit ihrem Gehalt in der Dampfphase, was unabdingbar eine Freisetzung chemischer Substanzen in die Atmosphäre bedingt. Selbst wenn diese Inhibitoren ungiftig und unschädlich sind, ist eine derartige Freisetzung doch vermeidbar, insbesondere dann, wenn beispielsweise Besteck oder Besteckteile zu schützen sind. Darüber hinaus muss die Verpackung immer fest geschlossen sein, da die Inhibitoren bei Anwesenheit der Luftschadstoffe, die ein Anlaufen verursachen, nicht oder weniger wirksam sind.Therefore, some attempts have already been made to propose storage means for tarnish-prone metal parts which prevent tarnishing or at least greatly slow it down. For example, DE-C-198 34 226 describes a tarnish-preventing agent for metal objects which can be used inside closed spaces, e.g. in packaging or showcases, can be used. The well-known anti-tarnish agent is a vapor-phase corrosion inhibitor, whose principle of action is based on the fact that it maintains or enhances the inherent, but mostly limited protective primary oxide layer formed very rapidly by contact with the atmosphere. The known vapor-phase corrosion inhibitors are present as powders and are introduced into the packaging in a suitable manner. The effectiveness of such corrosion inhibitors, however, depends on their content in the vapor phase, which inevitably causes a release of chemical substances into the atmosphere. Even if these inhibitors are non-toxic and harmless, such a release is nevertheless avoidable, especially if, for example, cutlery or cutlery are to be protected. In addition, the packaging must always be tightly closed because the inhibitors are not or less effective in the presence of the air pollutants that cause tarnishing.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Herstellen eines Aufbewahrungsmittels aufzuzeigen, mit dem Metallteile wirksam und unbedenklich gegen ein Anlaufen geschützt werden können.The invention has for its object to provide a method for producing a storage means, can be effectively and safely protected against tarnishing with the metal parts.

Die Aufgabe wird durch das Verfahren gemäß Anspruch 1 und das Aufbewahrungsmittel gemäß Anspruch 6 gelöst.The object is achieved by the method according to claim 1 and the storage means according to claim 6.

Durch die erfindungsgemäße Kombination eines mit einer Beflockung versehenen Aufbewahrungsmittels und einem Anlaufschutzmittel, das ein Opfermaterial enthält, wird zum einen durch die Beflockung eine stark vergrößerte Oberfläche zum Aufnehmen einer großen Menge des Anlaufschutzmittels bereitgestellt. Zum anderen werden durch das durch ein Opfermaterial wirkende Anlaufschutzmittel keine chemischen Substanzen in die Atmosphäre freigesetzt. Das Anlaufschutzmittel ist auch wirksam, wenn laufend Luftschadstoffe Zutritt haben. Durch die große Menge an Anlaufschutzmittel, die die Beflockung aufnehmen kann, hält der Anlaufschutz trotzdem sehr lange vor.The combination according to the invention of a flocking storage means and a tarnish protection agent containing a sacrificial material on the one hand provides a greatly enlarged surface for receiving a large amount of the tarnish protection agent by the flocking. On the other hand, no chemical substances are released into the atmosphere by the anti-tarnish agent acting through a sacrificial material. The anti-tarnish agent is also effective when airborne pollutants are present. Due to the large amount of anti-tarnish that can absorb flocking, the tarnish protection nevertheless lasts for a very long time.

Das Anlaufschutzmittel wird bevorzugt durch Tauchen aufgebracht, da damit eine besonders gleichmäßige und intensive Verteilung des Anlaufschutzmittels erreicht wird.The anti-tarnishing agent is preferably applied by dipping, as this is a particularly uniform and intensive distribution of the anti-tarnish agent is achieved.

Besonders bevorzugt wird zum Aufbringen des Anlaufschutzes ein Spülbad, insbesondere das Spülbad eines Färbeverfahrens für den Flock eingesetzt, so dass zum Aufbringen des Anlaufschutzmittels kein gesonderter Verfahrensschritt notwendig ist.For applying the tarnish protection, it is particularly preferred to use a rinsing bath, in particular the rinsing bath of a dyeing process for the flock, so that no separate process step is necessary for applying the tarnishing agent.

Das Anlaufschutzmittel sollte im Hinblick auf einen besonders hohen Dissoziationsgrad des Opfermaterials im Tauchbad ausgewählt werden, da dadurch eine besonders feine Verteilung und eine ionogene Form mit einer besonders hohen Reaktionsbereitschaft erreicht wird.The anti-tarnishing agent should be selected in view of a particularly high degree of dissociation of the sacrificial material in the dipping bath, as a particularly fine distribution and an ionic form is achieved with a particularly high responsiveness.

Zum Schutz von Silber oder Buntmetallen wird bevorzugt als Opfermaterial eine Silberverbindung, insbesondere Silbernitrat verwendet.For the protection of silver or non-ferrous metals, a silver compound, in particular silver nitrate, is preferably used as the sacrificial material.

Ein Ausführungsbeispiel des erfindungsgemäßen Verfahrens wird nachfolgend anhand Fig. 1 näher erläutert.An embodiment of the method according to the invention will be explained in more detail with reference to FIG. 1.

Fig. 1 zeigt in stark schematisierter Darstellung ein beispielhaftes Verfahren zum Herstellen eines Aufbewahrungsmittels 1 für Metallteile, insbesondere für versilberte Teile, Teile aus Massivsilber, Teile aus Kupfer, verkupferte Teile, Teile mit Oberflächen aus anderen Buntmetallen oder dgl. Besonders eignet sich das erfindungsgemäße Verfahren für Besteck, Münzen, Schmuck oder dgl. Das Aufbewahrungsmittel 1 ist im dargestellten Ausführungsbeispiel schalenförmig ausgebildet und kann beispielsweise als Einsatz für eine Umverpackung oder direkt als Verpackung oder Aufbewahrungsbehältnis dienen. Das Aufbewahrungsmittel 1 kann jedoch auch als Tuch zum Einwickeln oder Abdecken oder dgl. ausgebildet sein.1 shows a highly schematic representation of an exemplary method for producing a storage means 1 for metal parts, in particular for silver-plated parts, Parts of solid silver, parts of copper, copper parts, parts with surfaces of other non-ferrous metals or the like. The method of the invention is particularly suitable for cutlery, coins, jewelry or the like. The storage means 1 is cup-shaped in the illustrated embodiment and can be used, for example as an insert an outer packaging or directly serve as a packaging or storage container. However, the storage means 1 may be formed as a cloth for wrapping or covering or the like.

Das erfindungsgemäße Aufbewahrungsmittel wird bevorzugt durch eine einfache Abwandlung eines herkömmlichen Beflockungsverfahrens hergestellt. Gemäß Fig. 1 wird bei einem beispielhaften, herkömmlichen Beflockungsverfahren zunächst eine ausreichende Menge Flock bereitgestellt, bestehend aus äußerst kurzen, nicht mehr verspinnbaren oder verwebbaren Fasern, die eine Länge zwischen 0,5 bis 2 mm haben können. Der beim erfindungsgemäßen Verfahren eingesetzte Flock hat bevorzugt eine Faserlänge zwischen 1 mm und 1,5 mm. Der Flock kann aus Baumwollfasern, Viskosefasern, Polyamidfasern oder anderen geeigneten Fasern oder Filamenten hergestellt werden.The storage medium according to the invention is preferably produced by a simple modification of a conventional flocking process. 1, in an exemplary conventional flocking process, a sufficient amount of flock is initially provided, consisting of extremely short, no longer spinnable or weavable fibers, which may have a length of between 0.5 to 2 mm. The flock used in the method according to the invention preferably has a fiber length between 1 mm and 1.5 mm. The flock can be made from cotton fibers, viscose fibers, polyamide fibers or other suitable fibers or filaments.

Der Flock 2 wird zunächst in einer üblichen Färbeeinrichtung 3 eingefärbt und anschließend in Wasser gespült, was in einem oder mehreren Tauchbädern 4 geschieht.The flock 2 is first dyed in a conventional dyeing device 3 and then rinsed in water, which happens in one or more immersion baths 4.

Abweichend vom herkömmlichen Verfahren wird beim erfindungsgemäßen Verfahren in das einzige oder bevorzugt das letzte Tauchbad 4 ein Anlaufschutzmittel 5 zugegeben. Das Anlaufschutzmittel 5 liegt im Tauchbad 4 in wässriger Lösung vor und enthält ein Opfermaterial, wobei bevorzugt das Opfermaterial den einzigen Bestandteil des Anlaufschutzmittels bildet. Das Anlaufschutzmittel kann jedoch gegebenenfalls noch Zusätze enthalten, um beispielsweise die Benetzung zu verbessem oder dgl. Unter dem Begriff "Opfermaterial" soll ein Material verstanden werden, das eine größere chemische Reaktionsbereitschaft als das zu schützende Metall gegen den speziellen Schadstoff zeigt, gegen den das Metall durch das Anlaufschutzmittel geschützt werden soll. So wird beispielsweise Silber primär durch Schwefelverbindungen, insbesondere Schwefelwasserstoff, in der Luft angegriffen, wodurch sich die bekannte graue oder schwarze Anlaufschicht bildet. Als Opfermaterial eignet sich demzufolge besonders eine Silberverbindung, und insbesondere Silbemitrat, das einen hohen Dissoziationsgrad aufweist und somit in ionogener Form vorliegt. In dieser Form weist das Silbernitrat eine hohe Reaktionsfläche auf und ist somit wesentlich reaktionsbereiter als metallisches Silber oder die üblichen metallischen Silberlegierungen.Deviating from the conventional method, a tarnish-protection agent 5 is added to the single or preferably the last immersion bath 4 in the process according to the invention. The tarnish protection agent 5 is present in the immersion bath 4 in aqueous solution and contains a sacrificial material, with the sacrificial material preferably forming the sole constituent of the tarnish protection agent. However, the anti-tarnishing agent may optionally contain additives to improve, for example, the wetting or the like. The term "sacrificial material" is to be understood as a material that shows greater chemical reactivity than the metal to be protected against the specific pollutant against which the metal should be protected by the tarnishing agent. For example, silver is attacked primarily by sulfur compounds, in particular hydrogen sulfide, in the air, forming the known gray or black tarnish layer. As a sacrificial material is therefore suitable especially a silver compound, and in particular silver nitrate, which has a high degree of dissociation and thus is in ionogenic form. In this form, the silver nitrate has a high reaction surface and is thus much more responsive than metallic silver or the usual metallic silver alloys.

Das Anlaufschutzmittel 5 wird in ausreichender Menge zugegeben, um möglichst und im Wesentlichen die gesamte Oberfläche jeder Faser des Flocks 2 mit der wässrigen Lösung des Anlaufschutzmittels zu tränken und mit Anlaufschutzmittel zu besetzen. Zweckmäßige Mengen sind beispielsweise bis zu 6 kg auf 130 kg Flock. Wird weniger Anlaufschutzmittel verwendet, so beeinträchtigt dies nicht die generelle Schutzwirkung; nur die Zeitdauer des vollen Schutzes wird verringert.The anti-tarnish agent 5 is added in sufficient quantity to soak as possible and substantially the entire surface of each fiber of the flock 2 with the aqueous solution of the anti-tarnish agent and to occupy with anti-tarnish agent. Useful amounts are for example up to 6 kg to 130 kg of flock. If less tarnish protection agent is used, this does not affect the overall protective effect; only the duration of full protection is reduced.

Anschließend wird der mit Anlaufschutzmittel 5 getränkte Flock 2 in einer Trocknungseinrichtung 6 getrocknet und ist fertig zur Weiterverarbeitung.Subsequently, the soaked with anti-tarnish 5 flock 2 is dried in a drying device 6 and is ready for further processing.

Bei einer bevorzugten Weiterverarbeitung wird ein Träger 7 bereitgestellt. Der Träger 7 kann jedes geeignete Bahn- oder Plattenmaterial sein, ist jedoch bevorzugt eine Polystyrolbahn und wird beispielsweise von einem Coil abgewickelt. Auf den Träger 7 wird mit Hilfe einer Auftragseinrichtung 8 ein Klebstoff 9 aufgebracht und durch eine Rakel 10 zu einer gleichmäßig dicken Schicht egalisiert. Dann durchläuft der mit Klebstoff 9 beschichtete Träger 7 die insgesamt mit 11 bezeichnete Beflockungseinrichtung, die einen ersten Beflockungsschacht 12 aufweist. In diesen Beflockungsschacht wird der mit Anlaufschutzmittel getränkte und getrocknete Flock 2 eingeblasen, wobei die Fasern mit Hilfe einer Beflockungselektrode 13 senkrecht zum Träger 7 ausgerichtet werden. In einem weiteren Schacht 14 wird mit einer gegenpoligen Elektrode 15 nicht haftender Flock ausgetrieben und über eine Saugeinrichtung 16 entfemt. Anschließend kann der mit Klebstoff versehene und beflockte Träger 7 eine weitere Trocknungseinrichtung 17 durchlaufen, um den Klebstoff auszuhärten. Anschließend wird in einer Tiefzieheinrichtung 18 der beflockte Träger 7 geschnitten und zum Aufbewahrungsmittel 1 tiefgezogen.In a preferred further processing, a carrier 7 is provided. The carrier 7 may be any suitable sheet or plate material, but is preferably a polystyrene sheet and is unwound, for example, from a coil. On the carrier 7, an adhesive 9 is applied by means of an applicator 8 and equalized by a doctor blade 10 to a uniformly thick layer. Then coated with adhesive carrier 9 7 passes through the total designated 11 flocking device having a first Beflockungsschacht 12. In this flocking shaft impregnated with anti-tarnish and dried flock 2 is blown, wherein the fibers are aligned by means of a flocking 13 perpendicular to the carrier 7. In a further shaft 14 15 non-adherent flock expelled with a counter-pole electrode and removed via a suction device 16. Subsequently, the adhesive-provided and flocked carrier 7 can pass through a further drying device 17 to cure the adhesive. Subsequently, the flocked carrier 7 is cut in a deep-drawing device 18 and deep-drawn to the storage means 1.

In Abwandlung des beschriebenen und gezeichneten Ausführungsbeispiels kann beispielsweise das Anlaufschutzmittel auch aufgesprüht oder gestrichen werden. Obwohl die Verwendung eines Spülbads als Tauchbad besonders zweckmäßig ist, da dadurch ein weiterer Arbeitsschritt eingespart wird, ist es durchaus möglich, ein gesondertes Tauchbad einzig zum Aufbringen des Anlaufschutzmittels einzusetzen oder ein weiteres eventuell im Verlaufe des Verfahrens notwendig werdendes Tauchbad analog dem Spülbad beim Färben doppelt zu nutzen. Der Flock kann nach jedem bekannten Verfahren aufgebracht werden. Es ist weiterhin nicht unbedingt notwendig, dass das Verfahren, insbesondere im Bereich der Beflockungseinrichtung, kontinuierlich verläuft. So ist es beispielsweise möglich auch bereits vorgeformte und vorgeschnittene Träger nachträglich zu beflocken. Statt Silbernitrat kann beispielsweise auch Silbersulfat als Opfermaterial eingesetzt werden. Sollen andere Metalle gegen Schwefelverbindungen oder soll gegen andere Schadstoffe geschützt werden, so kann auch das Opfermaterial ein anderes sein.In a modification of the described and illustrated embodiment, for example, the tarnish protection can also be sprayed or painted. Even though the use of a rinsing bath as a dip is particularly useful because it saves a further step, it is quite possible to use a separate dipping only for applying the tarnish protection or another possibly necessary in the course of the process becoming immersion bath analogous to the rinse during dyeing twice use. The flock can be applied by any known method. Furthermore, it is not absolutely necessary for the process to be continuous, in particular in the area of the flocking device. Thus, for example, it is also possible to subsequently flock preformed and pre-cut carriers. Instead of silver nitrate, for example, silver sulfate can be used as a sacrificial material. If other metals are to be protected against sulfur compounds or if they are to be protected against other pollutants, then the sacrificial material can also be different.
