Description

Verfahren zum Verbinden von Kautschuk oder Kautschukersatzstoffen mit Metall Es ist bekannt, zum Verbinden von Kautschuk mit Metallen eine Kautschuklösung zu benutzen, der gepulverte Holzkohle zugesetzt ist. Bei diesem Verfahren ist jedoch eine vorherige sorgfältige Reinigung der Metalloberfläche erforderlich, was durchAuftragen eines Überzuges aus Fluß-, Reinigungs- und Gasentfernungsmitteln erfolgt. Dieses Verfahren wird zudem stufenweise angewendet und ist nicht sehr wirtschaftlich. Außerdem ist die erzielte Bindung eine sehr mangelhafte.Method of joining rubber or rubber substitutes with metal It is known to use a rubber solution for bonding rubber to metals to use, the powdered charcoal is added. However, this procedure is prior careful cleaning of the metal surface is required, which is achieved by applying a coating of flux, cleaning and gas removal agents takes place. This The process is also applied in stages and is not very economical. aside from that the bond achieved is a very poor one.

Es ist auch bekannt, zum Verbinden von Hartkautschuk mit Metall einen Kautschukmilchanstrich zu benutzen, bei dem ambrphe Bestandteile, wie Gips oder Zement, beigefügt werden. Diese Zusätze stellen jedoch die üblichen Füllmittel dar und haben keineswegs die Wirkung, die Bindung der Metalloberfläche mit demKautschuk zubeeinflussen oder gar zu verbessern.It is also known to bond hard rubber to metal one To use rubber milk paint, in which ambrphe components, such as plaster of paris or Cement, to be added. However, these additives are the usual fillers and in no way have the effect of binding the metal surface to the rubber to influence or even to improve.

Die Erfindung besteht nun in einem Verfahren zum Verbinden von Kautschuk oder Kautschukersatzstoffen mit Metall unter Anwendung eines amorphe Teile enthaltenden-Bindemittels mit dem. Kennzeichen, daß als amorpher Bestandteil Leder benutzt wird. Das Leder wird dem Bindemittel zweckmäßig in zerkleinerter Form zugefügt, was auch vor oder nach dem Aufstreichen des Bindemittels auf die Metalloberfläche, jedoch noch vor dessen Trocknung, erfolgen kann. Durch das Vorhandensein der Lederteile in amorpher Gestalt innerhalb des Bindemittels wird eine wesentliche Oberflächenvergrößerung der Bindefläche erzielt, so daß sich in gleicher Weise das Bindevermögen erhöht. Von wesentlicher Bedeutung ist, daß eine Vorbereitung der Metalloberfläche, z. B. das Anrauhen, sich nunmehr erübrigt, so daß sich das neue Bindeverfahren durch seine Einfachheit auszeichnet und also besonders wirtschaftlich ist. , Es ist lediglich ein einfacher Arbeitsgang notwendig, um die Metalloberfläche mit.der die amorphen Lederteile enthaltenden Bindemasse zu versehen. Auf diese wird der Kautschuk oder Kautschukersatzstoff aufgelegt. Die Vulkanisation erfolgt dann nach den für den jeweiligen Kautschukgegenstand in Betracht kommenden Verfahren. Die Bindung zwischen Metall und Kautschuk ist vollkommen einwandfrei und hält jeder Zug- und Scherbeanspruchung stand. Ausführungsbeispiel Entfettete, ungerauhte Metallteile werden mit einer Lösung von io Teilen Chlorkautschuk in ioo Teilen Toluol, der 15 Gewichtsprozent gemahlene Lederabfälle zugesetzt sind, z. B. durch Tauchen, Spritzen oder Streichen, überzogen. Nach dem Trocknen wird die Lösung einer unvulkanisierten Kautschukmischung aufgetragen, auf die trockene, rauhe Oberfläche. die zu befestigende Kautschukmischung aufgebracht und in bekannter Weise vulkanisiert. Es ist auch möglich, die gemahlenen Abfälle der Chlorkautschuk- und Kautschuklösung gleichzeitig zuzusetzen.The invention now consists in a method for bonding rubber or rubber substitutes to metal using a binder containing amorphous parts with the. Indicates that leather is used as an amorphous component. The leather is expediently added to the binder in comminuted form, which can also be done before or after the binder is spread onto the metal surface, but before it is dried. The presence of the leather parts in an amorphous shape within the binding agent results in a substantial increase in the surface area of the binding area, so that the binding capacity is increased in the same way. It is essential that a preparation of the metal surface, e.g. B. roughening is now unnecessary, so that the new binding process is characterized by its simplicity and is therefore particularly economical. All that is required is a simple operation to provide the metal surface with the binding compound containing the amorphous leather parts. The rubber or rubber substitute is placed on this. Vulcanization then takes place in accordance with the processes that come into consideration for the respective rubber article. The bond between metal and rubber is perfectly flawless and can withstand any tensile and shear stress. Embodiment Degreased, unroughened metal parts are mixed with a solution of 10 parts of chlorinated rubber in 100 parts of toluene to which 1 5 percent by weight of ground leather waste is added, e.g. B. by dipping, spraying or brushing coated. After drying, the solution of an unvulcanized rubber mixture is applied to the dry, rough surface. applied to the rubber mixture to be fastened and vulcanized in a known manner. It is also possible to add the ground waste to the chlorinated rubber and rubber solution at the same time.
