Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer mehrschichtigen Lackierung auf über beweglich gelagerte Klappen, Türen oder dergleichen zugänglichen Innenwandflächen und auf ungehindert zugänglichen Außenwandflächen eines Gegenstandes insbesondere zum Lackieren einer Fahrzeugkarosserie mit mindestens einer Basisschicht sowie mit mindestens einer farbigen Deckschicht. Bei diesem Verfahren sind Vorkehrungen zur Vermeidung der Verschmutzung des Gegenstandes während des Lackierens getroffen.The invention relates to a method for producing a Multi-layer paint on hinged flaps, doors or the like accessible inner wall surfaces and on unhindered accessible outer wall surfaces of an object, in particular for Painting a vehicle body with at least one base layer as well as with at least one colored cover layer. Precautions are required for this procedure Avoid pollution of the object during the Painting hit.
Das Verschmutzen zu lackierender Gegenstände während des Durchlaufs vom Rohteil bis zum Abschluß eines mehrstufigen Lackiervorganges ist nach wie vor die Hauptursache für kostenintensive Lacknacharbeiten. In größeren industriellen Anlagen, beispielsweise beim Lackieren von Fahrzeugkarosserien, legen diese zwischen und innerhalb der einzelnen Stationen große Strecken zurück und sind dort entsprechenden Umgebungseinflüssen ausgesetzt. Dabei lagern sich Staubpartikel, Fasern, z. B. von Kleidung, Schleifstaub oder gasförmige Medien auf den Oberflächen ab, die über elektrostatische Aufladung sehr fest dort haften und nur schwierig wieder zu entfernen sind. Die Folge sind beim nachfolgenden Lackauftrag Schmutz- und Fasereinschlüsse bzw. Benetzungsstörungen, die insbesondere bei hochwertigen und hochpreisigen Produkten wie Kraftfahrzeugen zu nicht akzeptablen Lackierergebnissen führen. Aus den genannten Gründen werden daher Vorkehrungen zur Vermeidung der Verschmutzung vor dem Lackieren bzw. zwischen den einzelnen Lackierstufen getroffen. Gängige Methoden hierzu sind die Einhausung von Förderstrecken durch teilweise belüftete Tunnel sowie auch die Anwendung der Reinraumtechnik.Contamination of objects to be painted during the run from the blank to the completion of a multi-stage painting process still the main cause of costly paint rework. In larger industrial plants, for example when painting Vehicle bodies, place them between and within each Stations long distances back and are corresponding there Exposed to environmental influences. Dust particles, fibers, e.g. B. of clothing, grinding dust or gaseous media on the Surfaces that adhere there very firmly via electrostatic charge and are difficult to remove. The result is the subsequent paint application dirt and fiber inclusions or Wetting disorders, particularly with high-quality and high-priced products such as motor vehicles too unacceptable Results in painting. For the reasons mentioned above, therefore Precautions to avoid contamination before painting or between the individual painting stages. Common methods of doing this are the housing of conveyor lines through partially ventilated tunnels as well as the use of clean room technology.
Eine gemäß Stand der Technik (DE 196 30 290 A1, DE 196 30 289 A1) praktizierte Prozeßfolge beim Lackieren von Fahrzeugkarosserien ist folgende: One according to the prior art (DE 196 30 290 A1, DE 196 30 289 A1) is practiced process sequence when painting vehicle bodies the following:
Um den Anforderungen an Elastizität und Schutz genügen zu können, Werden in einem mehrstufigen Verfahren eine Reihe von Schichten aufgetragen. Diese sind eine Zink-Phosphatschicht, eine Kataphorese-Grundierung und ein elastischer Steinschlagfüller als Basisschichten sowie ein die Farbe der Fahrzeugkarosserie bestimmender Decklack (uni, metallic oder Effekt-Lack), auf den generell noch ein Klarlack folgt, beides hier allgemein als Deckschichten bezeichnet.To be able to meet the requirements for elasticity and protection applied a number of layers in a multi-stage process. These are a zinc phosphate layer, a cataphoresis primer and an elastic stone chip filler as base layers and the color of the Top coat determining vehicle body (plain, metallic or effect paint), which is generally followed by a clear coat, both here generally as top layers designated.
Ein wirksamer Korrosionsschutz darf natürlich nicht bei der Lackierung enden. In weiteren Bearbeitungsschritten werden die Nähte abgedichtet, der Unterboden konserviert und Hohlräume mit Heißwachs versiegelt.Effective corrosion protection must of course not end with the painting. In further processing steps, the seams are sealed, the Preserved underbody and cavities sealed with hot wax.
Wenn die Rohkarosserie in die Lackieranlage kommt, ist ihre Oberfläche mit einem hauchdünnen Ölfilm und Resten von Ziehfett, das vor dem Pressen (Tiefziehen) auf die Bleche gesprüht wird, bedeckt. Die Karosserien müssen deshalb zunächst in einer Spritz- und Volltauchzone entfettet werden. In Phosphatier-Bädern erhalten die gereinigten Karosserien eine Zinkphosphat-Auflage. Sie dient als zusätzlicher Korrosionsschutz und Haftvermittler für die nachfolgende Grundierung. Die Zink-Phosphatschicht wird in einer Passivierzone nachgespült und verdichtet.When the body in white comes into the paint shop, its surface is included a wafer-thin oil film and remnants of drawing grease, which before pressing (Deep drawing) is sprayed onto the sheets, covered. The bodies have to therefore first degreased in a spray and full immersion zone. In The cleaned car bodies are given a phosphating bath Zinc phosphate coating. It serves as additional corrosion protection and Adhesion promoter for the subsequent primer. The zinc phosphate layer is rinsed and compacted in a passivation zone.
Es schließt sich eine Kataphorese-Grundierung der Karosserien an. Diese erfolgt im Tauchverfahren. Durch eine zwischen Karosserie und Tauchbekken angelegte elektrische Gleichspannung (ca. 300 Volt) werden die in Wasser gelösten Lackpartikel vom Blech angezogen und bleiben gleichmäßig auch an unzugänglichen Stellen haften. In einem nachgeschalteten Ofen wird die Grundierung eingebrannt (ca. 180 °C).This is followed by a cataphoretic primer for the bodies. This takes place in the immersion process. By a between body and diving tank applied DC voltage (approx. 300 volts) are the in Water-soluble paint particles are attracted to the sheet and remain adhere evenly to inaccessible places. In one the primer is baked in after the oven (approx. 180 ° C).
Nach Einbrennen der Grundierung und einem sich anschließenden Abdichten der Nähte werden Unterboden sowie Radhäuser mit Kunststoff beschichtet, wodurch die mechanische Widerstandsfähigkeit und der Langzeitschutz des Unterbodens erhöht wird. Diese Materialien werden in einem Trockner vorgeliert, die endgültige Trocknung erfolgt in den weiteren Bearbeitungsschritten.After stoving the primer and then sealing it the seams are coated with plastic on the underbody and wheel arches, thus the mechanical resistance and long-term protection of the sub-floor is raised. These materials are in a dryer pre-gelled, the final drying takes place in the further processing steps.
Zum Schutz vor Steinschlägen erfolgt anschließend eine elastische Grundierung mit dem sogenannten Steinschlag-Füller. Auch dieser wird nach Aufbringen anschließend in einem Trockenofen eingebrannt (bei ca. 150 ° C). Dadurch werden die Lackschichten widerstandsfähiger gegen mechanische Einflüsse und das Abplatzen des Decklackes wird weitgehendst vermieden.An elastic primer is then applied to protect against stone chips with the so-called stone chip filler. This will also follow Then apply baked in a drying oven (at approx. 150 ° C). This makes the paint layers more resistant to mechanical influences and chipping of the top coat largely avoided.
Es folgt eine Decklackierung in dem vom Kunden gewünschten Farbton. Beim Lackiervorgang werden die Lackpartikel durch ein elektrostatisches Feld von unter Hochspannung stehenden Spritzköpfen zu der geerdeten Karosserie transportiert. Zusätzlich erhalten alle Karossen eine Klarlackschicht.A top coat in the color desired by the customer follows. During the painting process, the paint particles are removed by an electrostatic Field of high voltage spray heads to the grounded Body transported. In addition, all bodies are given a clear coat.
Die fertig lackierten Karosserien werden anschließend einem Wachsflut-Verfahren unterzogen. Dabei werden die Hohlräume mit ca. 120 ° heißem Wachs konserviert. Mit dieser nochmaligen Steigerung des Korrosionsschutzes ist der Lackierprozeß beendet.The finished painted bodies are then subjected to a wax flood process subjected. The cavities become hot at approx. 120 ° Preserved wax. With this further increase in corrosion protection the painting process is finished.
Beim vorbeschriebenen Lackieren des Decklackes im Innenbereich (insbes. Motorraum, Kofferraum) des Fahrzeuges sowie der Tür-Randflächen (Einstiege) und Türrahmen mittels Spritzpistolen werden durch Öffnen von Motorhaube, Türen und Heckklappe, was für die Zugänglichkeit notwendig ist, Schmutzpartikel hochgewirbelt, die sich auf die Außenfläche des Fahrzeuges legen. Außerdem werden Partikel von Scharnieren gelockert, die ebenfalls an der Karosserie-Außenfläche Schmutz erzeugen.When painting the top coat in the interior as described above (esp. Engine compartment, trunk) of the vehicle and the door edges (Entrances) and door frames using spray guns are opened by opening Bonnet, doors and tailgate, what is necessary for accessibility is, particles of dirt whirled up on the outer surface of the Vehicle. In addition, particles are loosened from hinges, which also produce dirt on the outer surface of the body.
Der Erfindung liegt von daher die Aufgabe zugrunde, das gattungsgemäße Lackierverfahren dahingehend zu verbessern, daß gerade den letztgenannten Verschmutzungsproblemen vorgebeugt werden kann.The invention is therefore based on the object, the generic To improve painting processes so that just the the latter pollution problems can be prevented.
Dies gelingt erfindungsgemäß, wenn die im Kennzeichen das Patentanspruches 1 angegebene Verfahrensweise angewendet wird.This is achieved according to the invention if the Claim 1 specified procedure is applied.
Zweckmäßige Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.Appropriate developments of the invention are the subject of the dependent claims.
Der Kerngedanke der Erfindung ist also darin zu sehen, daß bei noch geöffneten Klappen, Türen oder dergleichen (bedingt durch den vorherigen Auftrag einer letzten Basisschicht) die Innenwandflächen mit der ersten Deckschicht versehen werden, so daß (vorzugsweise nach dem Trocknen dieser die Endbehandlung darstellenden Deckschicht) die Klappen, Türen oder dergleichen soweit möglich wieder geschlossen werden können. Eine Beschichtung mit Klarlack aus optischen und Korrosionschutz-Gründen ist bei den Innenwandflächen nicht erforderlich. Für das weitere Aufbringen der ersten Deckschicht und ggf. weiterer Deckschichten auf der Außenwandfläche müssen die Klappen und Türen dann nicht mehr geöffnet werden. The main idea of the invention is therefore to be seen in the fact that when it is still open Flaps, doors or the like (due to the previous order a last base layer) the inner wall surfaces with the first cover layer be provided so that (preferably after drying this the cover layer representing the final treatment) the flaps, doors or the like can be closed as far as possible. A coating with clear lacquer for optical and anti-corrosion reasons the inner wall surfaces are not required. For the further application of the first cover layer and possibly further cover layers on the outer wall surface the flaps and doors then no longer have to be opened.
In einer bevorzugten Weiterbildung der Erfindung, wie sie in Patentanspruch
2 angegeben ist, erfolgt der Auftrag der ersten Deckschicht auf die zuletzt
aufgebrachte Basisschicht an der Innenwandfläche "naß in naß". Die
Lackiertechnik "naß in naß" ist an sich im Stand der Technik bekannt (DE
34 35 937 C2, DE 38 06 257 C2), insofern, als zum Beispiel ein Metallic-Basislack
mit Klarlack und Klarlack mit dekorativem Lack möglichst schnell
nacheinander auf die Fahrzeugkarosserie aufgetragen werden. Im
zweitgenannten Dokument findet diese Technik bei der Zwei-Farben-Lackierung
Anwendung. Auch ist es bekannt (DE 27 40 246 A1) eine zweite
Grundierschicht auf eine erste "naß in naß" aufzutragen, um nach einer
Zwischentrocknung und Auftragen einer ersten Farbschicht auf diese
wiederum "naß in naß" eine weitere Farbschicht aufzutragen.In a preferred development of the invention as claimed in
Insbesondere beim Lackieren von Fahrzeugkarosserien bietet sich, wie
Patentanspruch 5 angibt, an die erste Farbschicht "naß in naß" auf den
zuvor aufgebrachten Steinschlagfüller aufzutragen.In particular when painting vehicle bodies, it can be seen how

Die Darstellung des bisherigen Standes der Technik nach Fig. 1 a ist selbsterklärend, wobei dem Reinigungsschritt in der Füllerkabine das Aufbringen von Grundierung und Unterbodenschutz vorgelagert ist, während dem Trocknen in der Decklackkabine noch eine Hohlraumkonservierung nachgeschaltet ist.The representation of the prior art according to Fig. 1 a self-explanatory, with the cleaning step in the filler cabin Applying primer and underbody protection is upstream while drying in the top coat booth still a cavity preservation is connected downstream.
Abweichend hierzu wird bei der in Fig. 1 b dargestellten erfindungsgemäßen Vorgehensweise bereits in der Füllerkabine nach dem Auftrag des Steinschlagfüllers innen und außen vorzugsweise "naß in naß" auch gleich in den in Fig. 2 gezeigten Innenwandbereichen der Decklack aufgebracht. In der später folgenden Decklackkabine ist es dann nur noch erforderlich, die Außenwand (Karosserieaußenfläche) mit Decklack zu versehen.Deviating from this, the invention shown in FIG. 1b Procedure already in the filler cabin after the order of the Stone chip filler inside and outside preferably "wet on wet" applied to the top coat in the inner wall regions shown in FIG. 2. In the subsequent topcoat booth, it is then only necessary to To provide the outer wall (outer surface of the body) with a top coat.
Die in Fig. 1b gezeigten Abläufe gelten bei Verwendung lösemittelhaltiger Lacke. Werden hingegen wasserlösliche Lacke verwendet, so ist es empfehlenswert, zwischen der Decklackapplikation - außen - und der Klarlackapplikation eine Zwischentrocknungsstufe vorzusehen. Der der Erfindung zugrunde liegende Gedanke bleibt hiervon jedoch unberührt. Ihr Einsatz bei Wasserlacken ist daher analog zu betrachten.The processes shown in FIG. 1b apply when using solvents Paints. However, if water-soluble paints are used, it is recommended that between the top coat application - outside - and the clear coat application to provide an intermediate drying stage. The basis of the invention however, the underlying idea remains unaffected. Your use at Water-based paints should therefore be viewed in the same way.
In Fig. 2 sind die Innenwandbereiche einer Fahrzeugkarosserie 1 gezeigt,
die bevorzugt bereits in der Füllerkabine eine Decklackbeschichtung erhalten
sollen. Es sind dies Motorraum 2, Motorhauben-Innenseite 3, Kofferraum
4, Kofferraumdeckel-Innenseite 5, Tür-Randflächen 6 und Türrahmen 7. Die
Karosserieaußenfläche 8 erhält, wie bisher üblich, in der Decklackkabine die
entsprechende Beschichtung. Eine Decklackbeschichtung des Fahrgastraumes
9 ist nicht vorgesehen.2 shows the inner wall regions of a vehicle body 1,
