Abstract

The method for connecting a rubber component with a powder-coated metal component using an adhesive system in a joint area between the metal component and rubber component, where heat is introduced to heat the joint area during the powder coating into the metal component, comprises applying a first component of a two-component adhesive system on a surface of the metal component in the joint area and drying the first component using the heat of the metal component, and applying a second component of the two-component adhesive system on the surface of the metal component in the joint area. The method for connecting a rubber component with a powder-coated metal component using an adhesive system in a joint area between the metal component and rubber component, where heat is introduced to heat the joint area during the powder coating into the metal component, comprises applying a first component of a two-component adhesive system on a surface of the metal component in the joint area and drying the first component using the heat of the metal component, applying a second component of the two-component adhesive system on the surface of the metal component in the joint area and drying the second component using the heat of the metal component, mounting the rubber component on the metal component in the joint area and clamping the rubber component with the metal component, and heating the joint area of rubber component and metal component so that the rubber component is combined with the adhesive system at the metal component. One component of the adhesive system is applied on the surface of the rubber component in the joint area. The rubber component is mounted on the metal component after drying a bonding agent. The joint area of rubber component and metal component is heated by the heat of the metal component, where the rubber component combines itself to the adhesive system bonded to the metal component. The adhesive system applies the components after spraying the metal component from the oven. A drying temperature of the bonding agent is cooled before applying the adhesive system on the metal component. The rubber component mounted on the metal component is heated using the oven, hot air, or by induction.

Description

Die Erfindung betrifft ein Verfahren zur Verbindung eines Gummibauteils mit einem pulverlackierten Metallbauteil.The invention relates to a method for connecting a rubber component with a powder-coated metal component.

Vor allem im Bereich der Kraftfahrzeugtechnik werden Metallbauteile beispielsweise in Form von Drehstabschulterlagern oder Stabilisatoren mit Gummibauteilen, hier insbesondere in Form von Gummilagern, verbunden. So zählt es beispielsweise zum Stand der Technik, die Gummilager auf ein Stabilisatorlager aufzuschieben und unter Spannung im Fahrzeug zu montieren. Alternativ hierzu kann das Gummilager auch mit dem Stabilisatorlager durch Vulkanisation des Gummilagers verbunden werden. Hierzu wird eine Fläche des Stabilisators vorher mit einem Haftungssystem behandelt, anschließend ein Gummilager auf den Stabilisator aufgeschoben und dieser Verbund in einem Ofen erhitzt, wobei sich durch die Wärmeeinwirkung das Gummilager mit dem Haftsystem, und somit auch mit dem Stabilisator verbindet.Especially in the field of automotive engineering metal components, for example in the form of Drehstabschulterlagern or stabilizers with rubber components, in particular in the form of rubber bearings, connected. For example, it is state of the art to postpone the rubber mountings to a stabilizer mount and to mount them under tension in the vehicle. Alternatively, the rubber bearing can also be connected to the stabilizer bearing by vulcanization of the rubber bearing. For this purpose, a surface of the stabilizer is previously treated with a bonding system, then pushed a rubber bearing on the stabilizer and this composite heated in an oven, which connects the rubber bearing with the adhesive system, and thus also with the stabilizer by the action of heat.

Der Nachteil hierbei ist, dass das Haftsystem vor der Montage ausgehärtet werden muss und dass nach der Montage des Gummilagers auf den Stabilisator der gesamte Verbund in einem Ofen erwärmt werden muss, was in einer relativ hohen Durchlaufzeit resultiert und somit hohe Prozesskosten zur Folge hat.The disadvantage here is that the adhesive system must be cured before mounting and that after assembly of the rubber bearing on the stabilizer of the entire composite must be heated in an oven, resulting in a relatively high throughput time and thus has high process costs.

Die Aufgabe der vorliegenden Erfindung wird darin gesehen, beim Verbinden eines Gummibauteils mit einem Metallbauteil die Prozesskosten zu reduzieren und gleichzeitig die Prozesszeit zu verkürzen.The object of the present invention is seen to reduce the process costs when connecting a rubber component with a metal component and at the same time to shorten the process time.

Die Lösung dieser Aufgabe wird in einem Verfahren mit den Maßnahmen des Patentanspruchs 1 gesehen.The solution to this problem is seen in a method with the measures of claim 1.

Vorteilhafte Maßnahmen des Verfahrens sind Gegenstand der abhängigen Unteransprüche.Advantageous measures of the method are the subject of the dependent subclaims.

Bei dem erfindungsgemäßen Verfahren wird ein Gummibauteil mit einem pulverlackierten Metallbauteil verbunden. Zur Verbindung von Gummibauteil und Metallbauteil wird in einem Fügebereich von Metallbauteil und Gummibauteil zusätzlich ein Haftsystem eingesetzt. Dabei wird die vorher während des Pulverlackierens in das Metallbauteil eingebrachte Wärme zur Erwärmung des Fügebereichs genutzt. Das bedeutet, dass die Verbindung des Gummibauteils mit dem Metallbauteil direkt im Anschluss an die Pulverlackierung des Metallbauteils erfolgt, und zwar bevor das Metallbauteil sich nach dem Einbrennen des Pulvers wieder auf Raumtemperatur abgekühlt hat.In the method according to the invention, a rubber component is connected to a powder-coated metal component. To connect the rubber component and the metal component, an adhesive system is additionally used in a joint area of metal component and rubber component. In this case, the heat previously introduced into the metal component during powder coating is used to heat the joint area. This means that the connection of the rubber component with the metal component takes place immediately after the powder coating of the metal component, before the metal component has cooled back to room temperature after the powder has been burnt in.

Prinzipiell ist es auch denkbar, das Metallbauteil auf eine definierte Aushärtetemperatur des Haftsystems abzukühlen. Dabei hängt die Aushärtetemperatur von dem jeweils ausgewählten Haftsystems ab. Durch eine zusätzliche Erwärmung kann, sofern dies zum Aushärten bzw. Trocknen des Haftsystems notwendig ist, das Metallbauteil auf einer bestimmten Temperatur gehalten werden. Durch die noch im Bauteil vorhandene Wärme entfällt der Schritt des Erwärmens des Metallbauteils und Energie wird nur zum Halten der Temperatur, nicht zum Erreichen der Temperatur benötigt.In principle, it is also conceivable to cool the metal component to a defined curing temperature of the adhesive system. The curing temperature depends on the particular adhesive system selected. By additional heating, if this is necessary for curing or drying of the adhesive system, the metal component can be kept at a certain temperature. By still existing in the component heat eliminates the step of heating the metal component and energy is needed only to maintain the temperature, not to reach the temperature.

Das Gummibauteil wird vorzugsweise vor dem Verbinden mit dem Metallbauteil vorvulkanisiert und vulkanisiert beim Erwärmen von Metallbauteil und Gummibauteil unter Verbindung mit dem Haftsystem aus.The rubber component is preferably pre-vulcanized prior to bonding to the metal component and vulcanized upon heating of the metal component and rubber component under connection with the adhesive system.

Das zur stoffschlüssigen Verbindung des Gummibauteils mit dem Metallbauteil eingesetzte Haftsystem wird im Fügebereich zwischen Gummibauteil und Metallbauteil aufgebracht. Bei einem solchen Haftsystem kann es sich beispielsweise um ein 2-komponentiges Haftsystem, bestehend aus einer ersten Komponente, beispielsweise einem Primer, und einer zweiten Komponente, beispielsweise einem Haftvermittler, handeln. Bei der Verwendung eines 2-komponentigen Haftsystems wird in einem ersten Schritt eine erste Komponente im Fügebereich auf eine Fläche des pulverlackierten Metallbauteils aufgebracht. Dies geschieht direkt im Anschluss an das Einbrennen des Pulvers in der Oberfläche des Metallbauteils. Die Trocknung der ersten Komponente erfolgt durch die noch im Metallbauteil vorhandene Wärme.The adhesive system used for the cohesive connection of the rubber component with the metal component is applied in the joining region between the rubber component and the metal component. Such an adhesive system can be, for example, a 2-component adhesive system consisting of a first component, for example a primer, and a second component, for example a bonding agent. When using a 2-component adhesive system, a first component in the joining region is applied to a surface of the powder-coated metal component in a first step. This happens directly after the burning of the powder in the surface of the metal component. The drying of the first component is effected by the heat still present in the metal component.

Nach dem Trocknen der ersten Komponente erfolgt das Aufbringen der zweiten Komponente auf die Fläche des Metallbauteils im Fügebereich. Auch die zweite Komponente auf der ersten Komponente wird durch die noch im Metallbauteil vorhandene Wärme getrocknet. Obwohl sich das Metallbauteil ohne zusätzliche Erwärmung beim Aufbringen des Haftsystems bereits abkühlt, reicht die verbleibende Restwärme aus, die erste Komponente und die zweite Komponente zu trocknen.After the first component has dried, the second component is applied to the surface of the metal component in the joining region. The second component on the first component is also dried by the heat still present in the metal component. Although the metal component already cools without additional heating during the application of the adhesive system, the residual heat remaining is sufficient to dry the first component and the second component.

Anschließend wird das Gummibauteil auf das Metallbauteil montiert. Nach einem Verspannen von Gummibauteil und Metallbauteil wird der Fügebereich erwärmt. Das Gummibauteil wird vollständig ausvulkanisiert, verbindet sich stoffschlüssig mit dem Haftsystem und über das Haftsystem mit dem Metallbauteil.Subsequently, the rubber component is mounted on the metal component. After clamping the rubber component and metal component, the joining area is heated. The rubber component is completely vulcanised, connects cohesively to the adhesive system and via the adhesive system with the metal component.

Der Vorteil dieser Prozessfolge liegt insbesondere darin, dass die erste Komponente und die zweite Komponente eines 2-komponetigen Haftsystems unter Ausnutzung der noch im Metallbauteil vorhandenen Wärme schneller getrocknet werden können als das bei Raumtemperatur oder einem gegebenenfalls notwendigen Erwärmen des Metallbauteils möglich wäre. Es ist also nicht nötig, zusätzlich Energie zuzuführen, um eine schnellere Trocknung der ersten Komponente und der zweiten Komponente zu erzielen. Gleichzeitig verkürzen sich die Prozesszeiten.The advantage of this process sequence is, in particular, that the first component and the second component of a 2-component adhesive system can be dried faster by utilizing the heat still present in the metal component than would be possible at room temperature or an optionally necessary heating of the metal component. It is therefore not necessary to additionally supply energy in order to achieve a faster drying of the first component and the second component. At the same time, the process times are shortened.

Alternativ zu 2-komponentigen Haftsystemen, können auch 1-komponentige Haftsysteme eingesetzt werden. Das Haftsystem kann direkt nach dem Einbrennen des Pulvers in eine Oberfläche des Metallbauteils auf eine Fläche im Fügebereich des Metallbauteils aufgebracht und durch die noch vorhandene Wärme im Metallbauteil getrocknet werden. Da hierbei nur das Haftsystem getrocknet werden muss, kann das Gummibauteil auf das noch erwärmte Metallbauteil montiert werden. Aufgrund der Restwärme im Metallbauteil reduziert sich die zur Erwärmung des Fügebereichs notwendige Energie. So wird die Fügetemperatur bzw. Vulkanisationstemperatur schneller erreicht. Die Prozesszeiten werden verkürzt.As an alternative to 2-component adhesive systems, 1-component adhesive systems can also be used. The adhesive system can be applied directly after the burning of the powder in a surface of the metal component on a surface in the joining region of the metal component and dried by the remaining heat in the metal component. Since only the adhesive system has to be dried in this case, the rubber component can be mounted on the still-heated metal component. Due to the residual heat in the metal component, the energy required to heat the joint area is reduced. Thus, the joining temperature or vulcanization temperature is reached faster. The process times are shortened.

Noch vorteilhafter ist es jedoch, das Gummibauteil parallel zur Pulverlackierung des Metallbauteils im Ofen mit dem Haftsystem zu versehen. Hierzu ist es gegebenenfalls vor dem Aufbringen des Haftsystems notwendig, das Gummibauteil im Fügebereich durch Entfetten oder Aufrauen vorzubehandeln, um eine bessere Haftung des Haftsystems zu erzielen. Das Haftsystem trocknet während der Pulverlackierung auf einer Fügefläche des Gummibauteils. Direkt im Anschluss an das Einbrennen des Pulvers wird das Gummibauteil auf das pulverlackierte Metallbauteil montiert und mit diesem verspannt. Dabei wird der Fügebereich von Gummibauteil und Metallbauteil durch die noch im Metallbauteil vorhandene Wärme erwärmt. Das Gummibauteil wird ausvulkanisiert und verbindet sich stoffschlüssig mit dem Haftsystem.However, it is even more advantageous to provide the rubber component in the oven with the adhesive system parallel to the powder coating of the metal component. For this purpose, it may be necessary to pre-treat the rubber component in the joint area by degreasing or roughening before applying the adhesive system in order to achieve better adhesion of the adhesive system. The adhesive system dries during the powder coating on a joining surface of the rubber component. Immediately following the burning in of the powder, the rubber component is mounted on the powder-coated metal component and braced with it. The joining area of rubber component and metal component is heated by the heat still present in the metal component. The rubber component is vulcanized and combines cohesively with the adhesive system.

Der Vorteil, das Gummibauteil und das Metallbauteil direkt nach der Pulverlackierung zusammenfügen zu können, liegt darin, dass im Metallbauteil noch viel Wärme vorhanden ist, welche in den sich anschließenden Prozessschritten genutzt werden kann. Dadurch kann gegebenenfalls eine weitere Erwärmung des gefügten Gummibauteils mit dem Metallbauteil sogar vollständig entfallen. Zudem ist es für eine prozesssichere Verbindung von Gummibauteil und Metallbauteil hilfreich, wenn das Metallbauteil vor dem Vulkanisationsprozess bereits erwärmt ist. Falls eine zusätzliche Erwärmung des Fügebereichs notwendig ist, erfolgt diese vorzugsweise in einem Ofen oder durch Heißluft. Ebenso ist es natürlich auch denkbar, das noch warme Metallbauteil durch Induktion zu erwärmen.The advantage of being able to join the rubber component and the metal component directly after the powder coating is that there is still a lot of heat in the metal component which can be used in the subsequent process steps. As a result, a further heating of the joined rubber component with the metal component may possibly even be completely eliminated. In addition, it is helpful for a reliable connection of rubber component and metal component, if the metal component is already heated before the vulcanization process. If additional heating of the joining area is necessary, this is preferably done in an oven or by hot air. Likewise, it is of course also conceivable to heat the still warm metal component by induction.

Allen vorgenannten Prozessfolgen ist gemein, dass die im Ofen in das Metallbauteil eingebrachte Wärme für Anschlussprozesse ausgenutzt wird. Darüber hinaus wird keine zusätzliche Prozesszeit und/oder Energie benötigt, um das Metallbauteil nach dem Pulverlackieren vor der weiteren Verarbeitung abzukühlen.All of the above-mentioned process sequences have in common that the heat introduced into the metal component in the furnace is utilized for connection processes. In addition, no additional process time and / or energy is needed to cool the metal component after powder coating prior to further processing.

Das Metallbauteil ist insbesondere ein Stabilisator eines Fahrwerks eines Kraftfahrzeugs, wobei das Gummibauteil Bestandteil eines Lagers (Drehstabschulterlager) des Stabilisators ist.The metal component is in particular a stabilizer of a chassis of a motor vehicle, wherein the rubber component is part of a bearing (torsion bar shoulder bearing) of the stabilizer.
