Definitions
- the invention relates to a method for producing a corrosion-protective coating on metallic substrates according to the preamble of claims 1 and 2.
- the object of the invention is to develop the known method for use in the packaging industry in such a way that, in addition to corrosion protection, the decorative design of metallic surfaces is simplified and the apparatus, work technology and energy expenditure previously required for this is reduced.
- Electrodeposition painting has also already been described in connection with the application of a coating to can bodies (DE-OS-2 024 106).
- the application of the corrosion-preventing lacquer is provided by immersing the can bodies of three-part cans after the completion of the can bodies before the bodies are provided with a bottom and filled.
- the question of a decorative print is not addressed in the previous publication. If such a decorative imprint were to be provided, it would have to be applied to the corrosion-preventing lacquer layer, which would cause considerable difficulties, which are in particular a risk of damage to the corrosion-preventing lacquer layer, which cannot be avoided by the mechanical stress on the can body during the printing process.
- the process according to claims 1 and 2 of the present invention dispenses with the otherwise necessary application of base coat on the outer surface of the can bodies and instead the decorative print is applied and cured as the first layer of paint, before either claiming 1 the decorative printing is supplemented or completed by the subsequent electrocoating, or before the entire can body is coated with a clearcoat according to claim 2 when using an electrically conductive coating for the decorative printing by electrocoating.
- the lacquer applied by the electrocoating may contain pigments as an additive to complete or complete the decorative print, which pigments were also included in the base lacquer application in the conventional method.
- pigments were also included in the base lacquer application in the conventional method.
- the areas remaining between the separate color fields of the decorative print are provided with a colored coating, which corresponds to the conventional base coat.
- the method according to claim 1 is based on the knowledge that, contrary to the instructions in EP-A-0 033 140, no noticeable The area of overlap between the first layer of paint, and thus the decorative print, and the dip coat applied by the subsequent electro-dip coating is created, but that due to the insulation resistance of the first coat of paint a sharp delimitation of this coat of paint is achieved by the electro-dip coating, but on the other hand none without a measurable overlap between the two paint coats Areas remain which are not adequately coated with a varnish and which could form areas at risk of corrosion. Since the electrodeposition coating determines the varnish as a function of the electrical conductivity between the can body and the counterelectrode, the varnish layer applied by the electrodeposition coating can be applied in the same thickness as the varnish layer of the decorative print. The sharp demarcation of the coating application forming the decorative print from the other surfaces coated by means of the dip coating is decisive for the usability of the method according to claim 1.
- the method of claim 2 is particularly useful for the manufacture of decorated cans, the outer surfaces of which are exposed to severe stress in the subsequent treatment. This is because the varnish applied to the decorative print creates a protective layer for this decorative print and at the same time achieves a corrosion-preventing coating on the surfaces not coated by the decorative print in a single operation.
- the aforementioned method is particularly recommended in those cases in which the outer surface of the can body has bare surfaces in addition to the decorative print or the color fields of the decorative print which are separated from one another are separated from one another by bare surface areas.
- the decorative print is applied to the bare can bodies in a manner similar to the method described above, and after this decorative print has hardened, the electrocoating is carried out with a clear varnish.
- the electrical conductivity of the varnish used for the decor printing can be adjusted so that the thickness of the varnish layer that arises on the color fields of the decor printing during electrodeposition coating is kept smaller than in the other areas.

Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines korrosionsschützenden Überzuges auf metallische Substrate gemäß dem Gattungsbegriff der Ansprüche 1 und 2.The invention relates to a method for producing a corrosion-protective coating on metallic substrates according to the preamble of claims 1 and 2.
Es sind Verfahren der vorgenannten Art bekannt (EP-A-0 033 140), bei denen auf einen Teil der Oberfläche der metallischen Substrate zunächst eine Lackschicht in Form eines Füllers aufgesprüht und gehärtet wird, ehe die Beschichtung der unbedeckten Oberfläche durch eine Elektrotauchlackierung aufgebracht und beide Schichten dann ausgehärtet werden. Dabei kommt es bei dem Füller auf eine bestimmte Zusammensetzung an sowie auf eine Überlappung der Elektrotauch-Grundierung und des Füllers, welche eine Breite von 2 bis 150 mm aufweisen soll. Ein besonderer Vorteil wird bei dem bekannten Verfahren darin gesehen, daß die Gesamtschichtdicke in der Überlappungszone immer größer ist, als die der Elektrotauch-Grundierung.Methods of the aforementioned type are known (EP-A-0 033 140), in which a lacquer layer in the form of a filler is first sprayed and hardened on part of the surface of the metallic substrates before the coating of the uncovered surface is applied by means of an electrocoating process and both layers are then cured. The filler depends on a certain composition and on an overlap of the electrocoat primer and the filler, which should have a width of 2 to 150 mm. A particular advantage in the known method is seen in the fact that the total layer thickness in the overlap zone is always greater than that of the electrodeposition primer.
Der Erfindung liegt die Aufgabe zugrunde, das bekannte Verfahren zur Verwendung in der Verpackungsindustrie so auszubilden, daß neben einem Korrosionsschutz die dekorative Gestaltung metallischer Oberflächen vereinfacht und der bisher hierfür erforderliche apparative, arbeitstechnische sowie Energie-Aufwand vermindert wird.The object of the invention is to develop the known method for use in the packaging industry in such a way that, in addition to corrosion protection, the decorative design of metallic surfaces is simplified and the apparatus, work technology and energy expenditure previously required for this is reduced.
Die Lösung vorstehender Aufgabe ergibt sich aus den Ansprüchen 1 und 2.The solution to the above problem results from claims 1 and 2.
Es ist bereits bekannt, Verpackungsdosen mit einem aufgedruckten Dekor zu versehen und die Dosen auf ihrer gesamten Oberfläche mit einem korrosionsschutz zu versehen, welcher bei Verwendung der Dosen für die Verpackung von Lebensmitteln oder Getränken von ganz besonderer Bedeutung ist.It is already known to provide packaging cans with a printed decor and to provide the cans with corrosion protection on their entire surface, which is of particular importance when the cans are used for packaging food or beverages.
Zum Aufbringen eines Dekors auf die äußere Umfangsfläche von Dosenrümpfen und einer die gesamte Dosenoberfläche überdeckenden Lackschicht werden bisher bei der praktischen Ausführung die nachfolgenden Verfahrensschritte durchgeführt:To apply a decor to the outer circumferential surface of can bodies and a lacquer layer covering the entire can surface, the following process steps have so far been carried out in practical implementation:
Auftrag eines den Untergrund für das spätere Dekor bildenden Lackauftrages.Application of a varnish that forms the base for the subsequent decor.
Trocknung und/oder Vernetzung des Grundlackes.Drying and / or crosslinking of the base coat.
Aufbringen des Dekors (Druck) auf den Grundlack der Außenfläche.Apply the decor (print) to the base coat of the outer surface.
Trocknung und/oder Vernetzung des aufgedruckten Dekors.Drying and / or cross-linking of the printed decor.
Bodenspritzlackierung zum Korrosionsschutz.Floor spray paint for corrosion protection.
Innenspritzlackierung zum Korrosionsschutz.Internal spray painting for corrosion protection.
Trocknung und/oder Vernetzung des Korrosionsschutzlackes.Drying and / or cross-linking of the anti-corrosion varnish.
Bei ggf. notwendiger Zweischicht-Lackierung müssen zwei weitere Schritte, nämlich eine weitere Innenspritzlackierung und eine weitere Trocknung bzw. Vernetzung, angeschlossen werden.If a two-layer coating is necessary, two further steps, namely a further interior spray coating and a further drying or crosslinking, must be connected.
Die Vielzahl der bisher notwendigen Verfahrensschritte zum Dekorieren und korrosionsverhindernden Lackieren von metallischen Dosenrümpfen erfordert einen großen maschinellen bzw. apparativen Aufwand und für die korrosionsverhindernde Beschichtung relativ große Mengen an Lack, da beim Auftragen des Lackes Toleranzen in der Schichtdicke nicht zu vermeiden sind und die geringste Schichtdicke noch ausreichen muß, um den Korrosionsschutz zu gewährleisten. Vorgenannte Voraussetzungen gelten auch für den Grundlackauftrag auf die Außenoberfläche, soweit dieser nicht durch den Dekordruck nochmals überdeckt wird.The large number of previously necessary process steps for decorating and corrosion-preventing painting of metal can bodies requires a great deal of mechanical and apparatus expenditure and for the corrosion-preventing coating relatively large amounts of coating, since tolerances in the layer thickness cannot be avoided when applying the coating and the smallest layer thickness must still be sufficient to ensure corrosion protection. The aforementioned requirements also apply to the application of the base coat on the outer surface, provided that this is not covered again by the decorative print.
Die Elektrotauchlackierung ist auch schon im Zusammenhang mit dem Auftrag einer Beschichtung auf Dosenrümpfe beschrieben worden (DE-OS-2 024 106). Bei diesem vorgenannten Verfahren zur Beschichtung von Dosenrümpfen ist der Auftrag des korrosionsverhindernden Lackes durch das Eintauchen der Dosenrümpfe von dreiteiligen Dosen nach der Fertigstellung der Dosenrümpfe vorgesehen, ehe die Rümpfe mit einem Boden versehen und gefüllt werden. Die Frage eines Dekoraufdruckes ist in der Vorveröffentlichung nicht angesprochen. Sollte ein solcher Dekoraufdruck vorgesehen sein, so müßte er auf die korrosionsverhindernde Lackschicht aufgebracht werden, wodurch erhebliche Schwierigkeiten entstehen würden, die insbesondere in einer Gefahr der Beschädigung der korrosionsverhindernden Lackschicht liegen, welche sich durch die mechanische Beanspruchung des Dosenrumpfes beim Druckvorgang nicht vermeiden lassen.Electrodeposition painting has also already been described in connection with the application of a coating to can bodies (DE-OS-2 024 106). In this aforementioned method for coating can bodies, the application of the corrosion-preventing lacquer is provided by immersing the can bodies of three-part cans after the completion of the can bodies before the bodies are provided with a bottom and filled. The question of a decorative print is not addressed in the previous publication. If such a decorative imprint were to be provided, it would have to be applied to the corrosion-preventing lacquer layer, which would cause considerable difficulties, which are in particular a risk of damage to the corrosion-preventing lacquer layer, which cannot be avoided by the mechanical stress on the can body during the printing process.
Gegenüber dem vorstehend beschriebenen Verfahren zum Dekorieren und korrosionsverhindernden Lackieren metallischer Dosenrümpfe wird durch das Verfahren nach den Ansprüchen 1 und 2 vorliegender Erfindung auf den sonst notwendigen Grundlackauftrag auf die Außenfläche der Dosenrümpfe verzichtet und stattdessen der Dekordruck als erste Lackschicht aufgebracht und ausgehärtet, ehe entweder nach Anspruch 1 der Dekordruck durch die nachfolgende Elektrotauchlackierung ergänzt bzw. vervollständigt wird, oder aber ehe gemäß Anspruch 2 bei Verwendung eines elektrisch leitenden Lackes für den Dekordruck durch die Elektrotauchlackierung der gesamte Dosenrumpf mit einem Klarlack beschichtet wird.Compared to the process for decorating and corrosion-preventing painting of metallic can bodies described above, the process according to claims 1 and 2 of the present invention dispenses with the otherwise necessary application of base coat on the outer surface of the can bodies and instead the decorative print is applied and cured as the first layer of paint, before either claiming 1 the decorative printing is supplemented or completed by the subsequent electrocoating, or before the entire can body is coated with a clearcoat according to claim 2 when using an electrically conductive coating for the decorative printing by electrocoating.
Bei dem Verfahren nach Anspruch 1 kann der durch die Elektrotauchlackierung aufgebrachte Lack zur Ergänzung bzw. Vervollständigung des Dekordruckes als Zusatz Pigmente enthalten, die bei dem herkömmlichen Verfahren auch in dem Grundlackauftrag enthalten waren. Mit einem derartig pigmentierten Tauchlack werden die zwischen den getrennten Farbfeldern des Dekordruckes verbleibenden Flächen mit einer farblichen Lackbeschichtung versehen, wie sie dem herkömmlichen Grundlack entspricht.In the method according to claim 1, the lacquer applied by the electrocoating may contain pigments as an additive to complete or complete the decorative print, which pigments were also included in the base lacquer application in the conventional method. With such a pigmented dip coating, the areas remaining between the separate color fields of the decorative print are provided with a colored coating, which corresponds to the conventional base coat.
Dem Verfahren nach Anspruch 1 liegt die Erkenntnis zugrunde, daß entgegen den Hinweisen in EP-A-0 033 140 kein merkbarer Überlappungsbereich zwischen der ersten und somit den Dekordruck darstellenden Lackschicht sowie dem durch die nachfolgende Elektrotauchlackierung aufgebrachten Tauchlack entsteht, sondern daß infolge des Isolationswiderstandes des ersten Lackauftrages eine scharfe Abgrenzung dieses Lackauftrages durch die Elektrotauchlackierung erreicht wird, jedoch andererseits auch ohne meßbare Überlappung zwischen den beiden Lackaufträgen keine Bereiche verbleiben, die nicht hinreichend mit einer Lackschicht versehen sind und korrosionsgefährdete Stellen bilden könnten. Da durch die Elektrotauchlackierung die Lackabscheidung in Abhängigkeit von der elektrischen Leitfähigkeit zwischen dem Dosenrumpf und der Gegenelektrode bestimmt wird, kann die durch die Elektrotauchlackierung aufgebrachte Lackschicht in gleicher Stärke aufgetragen werden, wie die Lackschicht des Dekordruckes. Die scharfe Abgrenzung des den Dekordruck bildenden Lackauftrages gegenüber den übrigen mittels des Tauchlackes beschichteten Flächen ist entscheidend für die Brauchbarkeit des Verfahrens nach Anspruch 1.The method according to claim 1 is based on the knowledge that, contrary to the instructions in EP-A-0 033 140, no noticeable The area of overlap between the first layer of paint, and thus the decorative print, and the dip coat applied by the subsequent electro-dip coating is created, but that due to the insulation resistance of the first coat of paint a sharp delimitation of this coat of paint is achieved by the electro-dip coating, but on the other hand none without a measurable overlap between the two paint coats Areas remain which are not adequately coated with a varnish and which could form areas at risk of corrosion. Since the electrodeposition coating determines the varnish as a function of the electrical conductivity between the can body and the counterelectrode, the varnish layer applied by the electrodeposition coating can be applied in the same thickness as the varnish layer of the decorative print. The sharp demarcation of the coating application forming the decorative print from the other surfaces coated by means of the dip coating is decisive for the usability of the method according to claim 1.
Das Verfahren nach Anspruch 2 ist besonders zweckmäßig für die Herstellung dekorierter Dosen, deren Außenoberflächen bei der späteren Behandlung einer starken Belastung ausgesetzt sind. Es wird nämlich durch den Lackauftrag auf den Dekordruck eine Schutzschicht für diesen Dekordruck geschaffen und dabei in einem einzigen Arbeitsgang gleichzeitig eine korrosionsverhindernde Beschichtung der nicht von dem Dekordruck beschichteten Flächen erreicht.The method of claim 2 is particularly useful for the manufacture of decorated cans, the outer surfaces of which are exposed to severe stress in the subsequent treatment. This is because the varnish applied to the decorative print creates a protective layer for this decorative print and at the same time achieves a corrosion-preventing coating on the surfaces not coated by the decorative print in a single operation.
Das vorgenannte Verfahren empfiehlt sich besonders in denjenigen Fällen, in denen die Außenoberfläche des Dosenrumpfes neben dem Dekordruck auch noch blanke Flächen aufweise bzw. die voneinander getrennten Farbfelder des Dekordruckes durch blanke Flächenbereiche voneinander getrennt sind. Bei dieser Ausgestaltung der Dosenrümpfe wird ähnlich wie bei dem zuvor beschriebenen Verfahren auf die blanken Dosenrümpfe der Dekordruck aufgebracht und nach dem härten dieses Dekordruckes die Elektrotauchlackierung mit einem Klarlack vorgenommen.The aforementioned method is particularly recommended in those cases in which the outer surface of the can body has bare surfaces in addition to the decorative print or the color fields of the decorative print which are separated from one another are separated from one another by bare surface areas. In this embodiment of the can bodies, the decorative print is applied to the bare can bodies in a manner similar to the method described above, and after this decorative print has hardened, the electrocoating is carried out with a clear varnish.
Dabei kann ggf. die elektrische Leitfähigkeit des für den Dekordruck verwendeten Lackes so eingestellt werden, daß die auf den Farbfeldern des Dekordruckes bei der Elektrotauchlackierung entstehende Lackschicht in ihrer Dicke geringer gehalten wird als in den übrigen Bereichen.If necessary, the electrical conductivity of the varnish used for the decor printing can be adjusted so that the thickness of the varnish layer that arises on the color fields of the decor printing during electrodeposition coating is kept smaller than in the other areas.
Durch die Folge der Aufbringung des Dekordruckes und die nachfolgende Elektrotauchlackierung wird bei allen Varianten des beschriebenen Verfahrens ein sicherer und vollflächiger Korrosionsschutz mit einer gegenüber dem Bekannten wesentlich geringeren Anzahl von Verfahrensschritten sowie gleichzeitiger Verminderung des Bedarfs an Beschichtungsmaterial erreicht.As a result of the application of the decorative print and the subsequent electrocoating, safe and full-surface corrosion protection is achieved in all variants of the described method with a significantly smaller number of process steps compared to the known method and a simultaneous reduction in the need for coating material.
