Abstract

Die Erfindung betrifft einen elastomeren Artikel (1) mit einer Gummimatrix (2) sowie in und/oder an die Gummimatrix (2) ein- und/oder anvulkanisierten Bauteilen (3), insbesondere Festigkeitsträger, einem Haftsystem, durch welches die ein- und/oder anvulkanisierten Bauteile (3) mit der Gummimatrix (2) verbindbar sind. Der Erfindung liegt die Aufgabe zugrunde, den Artikel (1) derart zu verbessern, dass die Haftung zwischen der Gummimatrix (2) und ein- und/oder anzuvulkanisierenden Bauteilen (3), insbesondere im Hinblick auf einen Formschlussanteil, verbessert ist. Zur Lösung dieser Aufgabe sind Nano-Tetrapoden 5 in der Haftvermittlerschicht 4 und der umgebenden Gummimatrix 2 eingebettet. Im vulkanisierten Zustand ist die Haftvermittlerschicht 4 in die Gummimatrix 2 übergegangen und die Tetrapoden 5 sind sowohl mit der Oberfläche 7 des Bauteils 3 als auch mit der Gummimatrix 2 verkrallt. Die Haftung zwischen Gummimatrix 2 und dem Bauteil 3 beruht dabei einerseits auf der chemischen Bindung zwischen Oberfläche 7 des Bauteils 3 und der Gummimatrix 2, andererseits auf der formschlüssigen Verkrallung der Tetrapoden 5 mit der Oberfläche 7 und der Gummimatrix 2.The invention relates to an elastomeric article (1) having a rubber matrix (2) and components (3) embedded in and / or to the rubber matrix (2), in particular reinforcing elements, an adhesive system by which the on and / or or vulcanized components (3) with the rubber matrix (2) are connectable. The object of the invention is to improve the article (1) in such a way that the adhesion between the rubber matrix (2) and the components (3) to be vulcanized and / or vulcanised is improved, in particular with regard to a form-fit component. To solve this problem, nano-tetrapods 5 are embedded in the adhesion promoter layer 4 and the surrounding rubber matrix 2. In the vulcanized state, the adhesion promoter layer 4 has merged into the rubber matrix 2 and the tetrapods 5 are clawed both with the surface 7 of the component 3 and with the rubber matrix 2. The adhesion between the rubber matrix 2 and the component 3 is based on the one hand on the chemical bond between the surface 7 of the component 3 and the rubber matrix 2, on the other hand on the form-locking clawing of the tetrapods 5 with the surface 7 and the rubber matrix. 2

Description

Die Erfindung betrifft einen elastomeren Artikel mit einer Gummimatrix sowie in und/oder an die Gummimatrix ein- und/oder anvulkanisierten Bauteilen, insbesondere Festigkeitsträger, mit einem Haftsystem, durch welches die ein- und/oder anvulkanisierten Bauteile mit der Gummimatrix verbindbar sind. The invention relates to an elastomeric article having a rubber matrix as well as components embedded in and / or vulcanized on the rubber matrix, in particular reinforcing members, with an adhesive system by means of which the on- and / or vulcanised components can be connected to the rubber matrix.

Derartige Artikel, beispielsweise Luftfederbälge, Kfz-Luftreifen oder Kraftübertragungsriemen sind seit langem bekannt und in Benutzung. Dabei dienen insbesondere die in die Gummimatrix eingebetteten Festigkeitsträger, beispielsweise textile Gewebe, metallische Fadenkonstruktionen oder ähnliches im Wesentlichen dazu, die auf die Artikel wirkenden Kräfte zu übertragen, da die Gummimatrix aufgrund ihres elastischen Verhaltens dazu meist nicht ausreichend in der Lage ist. Such articles, such as air bags, automotive pneumatic tires or power transmission belts have long been known and in use. In particular, the reinforcing members embedded in the rubber matrix, for example textile fabrics, metallic thread constructions or the like, essentially serve to transfer the forces acting on the articles, since the rubber matrix is usually insufficiently able to do so because of its elastic behavior.

Da die genannten Artikel meist einer elastischen Wechselbelastung unterworfen sind, ist insbesondere auf eine gute Haftung zwischen der Gummimatrix und den ein- und/oder anzuvulkanisierenden Bauteilen zu achten, da es ansonsten zu einem vorzeitigen Versagen der Artikel kommen kann. Since the said articles are usually subjected to an elastic alternating load, attention must be paid in particular to good adhesion between the rubber matrix and the components to be vulcanized and / or vulcanised, since otherwise the articles may prematurely fail.

Um die Haftung zwischen Gummimatrix und den ein- und/oder anzuvulkanisierenden Bauteilen zu ermöglichen oder zu verbessern, ist es bekannt, die Bauteile vor der Einbettung in die Gummimatrix mit Haftvermittlern zu beschichten, die bei der Vulkanisation der Artikel eine gute Verankerung der ein- und anzuvulkanisierenden Bauteile in der Matrix gewährleisten. Diese Verankerung beruht im Wesentlichen auf einer chemischen, weniger einer formschlüssigen Verbindung. In order to facilitate or improve the adhesion between the rubber matrix and the components to be vulcanized and / or vulcanized, it is known to coat the components with adhesion promoters prior to embedding in the rubber matrix, which ensure good anchoring of the on and off elements during vulcanization Ensure components to be vulcanized in the matrix. This anchoring is based essentially on a chemical, less a positive connection.

In der DE 10 2008 037 417 A1 , der EP 2 594 414 A1 oder der US 4,218,349 B1 sind derartige Haftsysteme offenbart. In the DE 10 2008 037 417 A1 , of the EP 2 594 414 A1 or the US 4,218,349 B1 such adhesive systems are disclosed.

An der Universität Kiel wurde ein Verfahren entwickelt, welches durch eine rein formschlüssige Wirkung die Verbindung zweier Materialien ermöglicht, die anderweitig nicht oder nur ungenügend miteinander verbindbar sind, z.B. Teflon und Silikon. Die Entwicklung ist in der Zeitschrift Produktion Nr. 37/2012 veröffentlicht. At the University of Kiel, a method has been developed which, by means of a purely interlocking effect, enables the connection of two materials which are otherwise not or only insufficiently connectable, e.g. Teflon and silicone. The development is published in the magazine Production No. 37/2012.

Dazu ist in das jeweilige Bauteil eine vorbestimmte Menge an sogenannten Nanotetrapoden eingebettet. Nanotetrapoden sind tetrapodenförmig ausgebildete Kristalle, hier aus Zinkoxid, mit einer Größe von mehreren Nano- bis zu wenigen Mikrometern. Diese Tetrapoden bzw. deren Arme ragen mindestens teilweise aus der Oberfläche der jeweiligen Bauteile heraus und bilden bei Kontakt zweier derart ausgerüsteter Teile eine Art Klettverschluss, der eine gewisse Haftungskraft zwischen den Bauteilen aufbaut, die allein aufgrund des formschlüssigen Verhakens der aus der Oberfläche herausragenden Tetrapoden-Arme beruht. Dieses Verfahren basiert jedoch auf der Tatsache, dass mindestens eine möglichst hohe Anzahl von Tetrapoden-Armen aus der Oberfläche der Bauteile herausragt. Dieses Verhalten ist bei den eingangs genannten elastomeren Artikeln unerwünscht. For this purpose, a predetermined amount of so-called nanotetrapods is embedded in the respective component. Nanotetrapods are tetrapod-shaped crystals, here of zinc oxide, with a size of several nano- to a few microns. These tetrapods or their arms protrude at least partially out of the surface of the respective components and, upon contact of two parts thus equipped, form a kind of hook-and-loop fastener which builds up a certain adhesive force between the components, which is due solely to the positive interlocking of the tetrapod protruding from the surface. Arms based. However, this method is based on the fact that at least as many tetrapod arms as possible protrude from the surface of the components. This behavior is undesirable in the case of the elastomeric articles mentioned at the outset.

Der Erfindung liegt die Aufgabe zugrunde, den eingangs genannten Artikel derart zu verbessern, dass die Haftung zwischen der Gummimatrix und ein- und/oder anzuvulkanisierenden Bauteilen, insbesondere im Hinblick auf einen Formschlussanteil, verbessert ist. The object of the invention is to improve the article mentioned at the outset in such a way that the adhesion between the rubber matrix and components to be vulcanized and / or vulcanized is improved, in particular with regard to a form-fit component.

Diese Aufgabe wird dadurch gelöst, dass der Artikel ein Haftsystem aufweist, welches folgende Merkmale aufweist, nämlich
vor der Vulkanisation

  • – mit Haftvermittler beschichtete ein- und/oder anzuvulkanisierende Bauteile,
  • – eine die ein- und/oder anzuvulkanisierenden Bauteile umgebende Rohgummimatrix,
  • – in die Haftvermittlerschicht eingebettete Nanotetrapoden, die zumindest mit mehreren Armen aus der Haftvermittlerschicht herausragen und in die umgebende Rohgummimatrix eingreifen,
wobei nach der Vulkanisation die ein- und/oder anzuvulkanisierenden Bauteile sowohl durch die bei der Vulkanisation entstandene chemische Bindung als auch durch formschlüssige Wechselwirkung der Nanotetrapoden mit der Oberfläche der ein- und/oder anzuvulkanisierenden Bauteile und der Gummimatrix fest miteinander verbunden sind. This object is achieved in that the article has an adhesive system, which has the following features, namely
before vulcanization
  • - components coated with adhesion promoter and / or to be vulcanized,
  • A raw rubber matrix surrounding the components to be vulcanized and / or vulcanised,
  • Embedded in the adhesive layer nanotetrapods that protrude from the adhesive layer at least with several arms and engage in the surrounding raw rubber matrix,
wherein after vulcanization the components to be vulcanized and / or vulcanized are firmly connected to one another both by the chemical bond formed in the vulcanization and by positive interaction of the nanotetrapods with the surface of the components to be vulcanized and / or vulcanized.

Auf diese Weise ist ein Haftsystem gebildet, welches aufgrund der Wirkung der Tetrapoden, wirrgutartig ineinander zu greifen und sich gegenseitig zu verhaken, zusätzlich zu der chemischen Bindung der ein- und/oder anzuvulkanisierenden Bauteile mit der Gummimatrix über die Haftvermittlerschicht auch einen formschlüssigen Verbund zwischen den ein- und/oder anzuvulkanisierenden Bauteilen und der Gummimatrix aufweist. In this way, an adhesive system is formed, which, due to the action of the tetrapods, engage each other like a tangle and snag each other, in addition to the chemical bonding of the components to be vulcanized and / or vulcanized to the rubber matrix via the primer layer, also a positive bond between them having and / or vulcanizing components and the rubber matrix.

Der Vorteil dieses Haftsystems liegt darin, dass durch den Formschlussanteil zusätzlich Haftkraft entsteht, so dass der Artikel eine höhere Sicherheit gegen eine ungewollte Trennung der ein- und/oder anzuvulkanisierenden Bauteile von der Gummimatrix aufweist. The advantage of this adhesive system is that additional adhesive force is created by the form-fitting component, so that the article has a higher security against unwanted separation of the components to be vulcanized and / or vulcanized from the rubber matrix.

Der Artikel 1 weist eine Gummimatrix 2, ein ein- und/oder anzuvulkanisierendes Bauteil 3, eine Haftvermittlerschicht 4 und Nanotetrapoden 5 auf, wobei die Nanotetrapoden 5 in die Haftvermittlerschicht 4 derart eingebettet sind, dass Arme 6 der Tetrapoden 5 sowohl innerhalb der Haftvermittlerschicht 4 wirrgutartig ineinander greifen, also auch mindestens teilweise in die umgebende Gummimatrix 2 hineinragen. It shows 1 a section of an elastomeric article according to the invention 1 in unvulcanized state. The item 1 has a rubber matrix 2 , a component to be vulcanized and / or vulcanised 3 , a primer layer 4 and nanotetrapods 5 on, with the nanotetrapods 5 in the primer layer 4 are embedded in such a way that arms 6 the tetrapods 5 both within the primer layer 4 intertwined, so at least partially in the surrounding rubber matrix 2 protrude.

Die 2 zeigt den gleichen Artikel 1 im vulkanisierten Zustand. Dabei ist die Gummimatrix 2 fest und untrennbar mit dem Bauteil 3 verbunden, wobei durch den Vulkanisationsprozess die Haftvermittlerschicht 4 in die Gummimatrix 2 übergegangen ist. Die Tetrapoden 5 sind sowohl mit der Oberfläche 7 des Bauteils 3 als auch mit der Gummimatrix 2 verkrallt. Die Haftung zwischen Gummimatrix 2 und dem Bauteil 3 beruht dabei einerseits auf der chemischen Bindung zwischen Oberfläche 7 des Bauteils 3 und der Gummimatrix 2, andererseits auf der formschlüssigen Verkrallung der Tetrapoden 5 mit der Oberflächen 7 und der Gummimatrix 2. The 2 shows the same article 1 in the vulcanized state. Here is the rubber matrix 2 firm and inseparable from the component 3 connected, wherein by the vulcanization process, the adhesion promoter layer 4 in the rubber matrix 2 has passed. The tetrapods 5 are both with the surface 7 of the component 3 as well as with the rubber matrix 2 digs. The adhesion between rubber matrix 2 and the component 3 is based on the one hand on the chemical bond between the surface 7 of the component 3 and the rubber matrix 2 on the other hand, on the positive locking of the tetrapods 5 with the surfaces 7 and the rubber matrix 2 ,
