Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren der im Oberbegriff des ersten An spruchs angegebenen Art.The invention relates to a method in the preamble of the first to Art.
Im Automobilbau ist es üblich, daß verschiedene Bauteile an der fertig lackierten Karosserie angeklebt werden. So werden beispielsweise Türdichtungen auf die Tür bzw. den Türausschnitt der Karosserie aufgeklebt, Zierleisten an Türaußenseiten und vieles weitere mehr. Die Klebung muß so ausgeführt werden, daß die anzukle benden Bauteile über Jahre hinaus an Ort und Stelle bleiben und insbesondere nicht durch Witterungseinflüsse wie Temperatur, Kälte, Regen, Streusalze oder Wasch anlagen abgelöst werden.In automotive engineering, it is common for various components to be painted on the finished Body to be glued. For example, door seals are placed on the door or the door cutout of the body glued on, trim strips on the outside of the door and much more. The gluing must be carried out so that the glue components remain in place for years and in particular not due to weather influences such as temperature, cold, rain, road salt or washing plants will be replaced.
Aus diesem Grunde ist es erforderlich, den Bereich, an dem ein Bauteil angeklebt wird, vorher zu reinigen. Dies geschieht mit Hilfe von Lösungsmitteln und Einweg tüchern sowie individuell durch Werker. Bei einer derartigen Vorgehensweise ist es notwendig, eine Ablüftzeit von mindestens 1 Minute einzuhalten, was bedeutet, daß die Reinigung einige Takte vor der eigentlichen Verklebung erfolgen muß. Hierbei ist eine Neuverschmutzung der Klebefläche in der Zwischenzeit nicht ausgeschlossen. Ebenso ist nicht ausgeschlossen, daß die Reinigung der Aufnahmefläche jeweils mit der erforderlichen Sorgfalt durchgeführt wird. For this reason, it is necessary to identify the area to which a component is glued is going to clean beforehand. This is done with the help of solvents and disposable towels as well as individually by workers. With such an approach, it is necessary to allow a flash-off time of at least 1 minute, which means that the cleaning must be done a few bars before the actual gluing. Here is a new contamination of the adhesive surface in the meantime is not excluded. It is also not excluded that the cleaning of the receiving surface with each the necessary care is taken.
Aufgabe der vorliegenden Erfindung ist es, hier Abhilfe zu schaffen und den Reini gungsvorgang zu vereinfachen.The object of the present invention is to remedy this situation and the Reini simplification process.
Dies wird erfindungsgemäß durch die Merkmale des ersten Anspruchs erreicht. Durch die Behandlung der das anzuklebende Bauteil aufzunehmenden Fläche mit Hilfe einer Flamme, der ein Haftvermittler zugesetzt ist, entfallen die Einwegtücher und das Lösungsmittel und damit auch die Ablüftzeit. Durch diese Vorgehensweise wird die behandelte Fläche auf einen energetisch günstigeren Zustand gebracht.This is achieved according to the invention by the features of the first claim. By treating the surface to be glued with the component With the help of a flame to which an adhesion promoter has been added, disposable wipes are not required and the solvent and thus the flash-off time. By doing this the treated area is brought to an energetically more favorable condition.
Es wurde überraschenderweise festgestellt, daß dieser energetisch günstigere Zustand sogar mehrere Tage andauert, so daß die Verklebung theoretisch auch einige Tage nach der erfindungsgemäßen Behandlung durchgeführt werden könnte, wenn in der Zwischenzeit sichergestellt werden kann, daß keine erneute Verschmutzung eintreten kann.It was surprisingly found that this is more energetically favorable Condition lasts even several days, so that the bonding theoretically too could be carried out a few days after the treatment according to the invention, if it can be ensured in the meantime that no renewed Pollution can occur.
Somit ist es vorteilhaft, die Reinigung direkt vor dem Klebvorgang durchzuführen, so daß die bisher mögliche Neuverschmutzungsmöglichkeit zwischen Reinigung und Ankleben nicht mehr eintreten kann.It is therefore advantageous to carry out the cleaning directly before the gluing process that the previously possible possibility of new pollution between cleaning and Sticking can no longer occur.
Ein weiterer Vorteil liegt darin, daß durch die Flamme die vorzubehandelnde Fläche erwärmt wird, was gerade in Wintermonaten positiv ist, weil ein sicheres Verkleben nur ab einer Mindesttemperatur möglich ist.Another advantage is that the surface to be pretreated by the flame is heated, which is positive in winter months in particular because it sticks securely is only possible from a minimum temperature.
Als Brenngas kann Propan, Butan, Erdgas oder Stadtgas eingesetzt werden, als Haftvermittler, der sich für die Klebflächenaktivierung an lackierten Bauteilen, die mit einem lösungsmittelhaltigen Einkomponenten-Klarlack behandelt sind, eignet sich eine siliziumorganische Verbindung wie SiO2, die in den Brenner eingespeist wird. Sie ist im Handel unter der Bezeichnung Silan verfügbar.Propane, butane, natural gas or town gas can be used as the fuel gas, and an organosilicon compound such as SiO 2 , which is fed into the burner, is suitable as an adhesion promoter, which is suitable for activating the adhesive surface on painted components that have been treated with a solvent-containing one-component clear coat . It is commercially available under the name silane.
Die Vorbehandlung von weiterzuverarbeitenden Bauteilen mit Hilfe einer Flamme, die sogenannte Flammpyrolyse, ist bei Kunststoffbauteilen bekannt, um hier die für eine spätere Lackierung notwendige Vorbehandlung, nämlich die Versiegelung der Kunststoffoberfläche, durchzuführen. Der Einsatz der Flammpyrolyse an lackierten Bauteilen, die mit einem lösungsmittelhaltigen Einkomponenten-Klarlack lackiert wurden, wurde jedoch bisher nicht für möglich gehalten.The pretreatment of components to be processed using a flame, the so-called flame pyrolysis, is known in plastic components, here for a subsequent painting necessary pretreatment, namely the sealing of the Plastic surface. The use of flame pyrolysis on painted Components that are coated with a solvent-based one-component clear lacquer have not yet been considered possible.
Die Weiterbildung nach Anspruch 2 hat den Vorteil, daß der Klebflächen aktivierungsvorgang automatisiert werden kann, da es wesentlich einfacher ist, einen Roboter mit einer offenen Flamme entlang einer Aktivierungsfläche zu steu ern, als dies möglich wäre, wenn der Roboter ein Reinigungstuch bedienen müßte.The development according to claim 2 has the advantage that the adhesive surfaces activation process can be automated as it is much easier to steer a robot with an open flame along an activation surface than would be possible if the robot had to operate a cleaning cloth.
Die Verwendung einer Miniaturflamme hat den Vorteil, daß die Aktivierungsfläche der Aufnahmefläche für das anzuklebende Bauteil angepaßt werden kann, so daß das Gasgemisch mit dem Haftvermittler optimal eingesetzt werden kann. Dies ist insbesondere dann von Vorteil, wenn Türdichtungen oder Zierleisten, also Bauteile mit einer geringen Breite aber großen Länge, angeklebt werden sollen.The use of a miniature flame has the advantage that the activation area the receiving surface for the component to be glued can be adjusted so that the gas mixture with the adhesion promoter can be used optimally. This is This is particularly advantageous if door seals or trim strips, i.e. components with a small width but a large length.
Mit dem erfindungsgemäßen Verfahren können Flächen aktiviert werden mit bis zu 800 mm pro Sekunde. Hierbei können die üblichen Verschmutzungen, wie Hand schweiß, Polierwachsreste, Hohlraumwachs o. ä. problemlos entfernt werden, so daß anschließend das anzuklebende Bauteil aufgeklebt werden kann.With the method according to the invention, areas can be activated with up to 800 mm per second. Here, the usual dirt, such as hand Sweat, polishing wax residues, cavity wax or the like can be removed without problems, see above that the component to be glued can then be glued on.
Es hat sich auch herausgestellt, daß die Klebstoff-Flächen-Aktivierung mehrere Tage anhält, so daß der Anklebvorgang erst später durchgeführt werden kann, wenn in der Zwischenzeit sichergestellt ist, daß keine Neuverschmutzung eintritt.It has also been found that the adhesive surface activation has several Days lasts, so that the gluing process can only be carried out later when in the meantime it is ensured that no new pollution occurs.
