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 durch Auftragen 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: Es ist auch bekannt, zum Verbinden von Hartkautschuk mit Metall einen Kautschukmilch anstrich zu benutzen, bei dem amorphe Bestandteile, wie Gips oder Zement, zugefügt werden. Diese Zusätze stellen jedoch die üblichen Füllmittel dar und haben keineswegs die Wirkung, die Bindung der Metalloberfläche mit dem Kautschuk zu beeinflussen oder gar zu verbessern.Method of joining rubber or rubber substitutes with metal. It is known to use a rubber cement to bond 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 due to Application of a coating of flux, cleaning and gas removal agents takes place. This process is also used in stages and is not very economical. In addition, the bond achieved is very poor: it is also known to use a rubber milk paint to connect hard rubber with metal, in which amorphous components such as plaster of paris or cement are added. These additions however represent the usual fillers and in no way have the effect that To influence or even improve the bonding of the metal surface with the rubber.
Die Erfindung besteht nun in einem Verfahren zum Verbinden von Kautschuk oder Kautschukersatzstoffen mit Metall unter An-Wendung eines amorphe Teile enthaltenden Bindemittels mit dem Kennzeichen, daß als amorpher Bestandteil Kautschuk benutzt wird. Unter Kautschuk sind alle bekannten Kautschuksorten, wie z. B. Rohkautschuk, vulkanisierter Kautschuk, Kautschukabfälle, Kunstkautschuk und kautschukähnliche Kunststoffe, zu verstehen. In dem Kautschuk können in üblicher Weise auch die bekannten Zusatz-und Füllstoffe enthalten sein. Der Kautschuk wird dem Bindemittel zweckmäßig in Krümeln oder als Staub zugefügt, was auch vor oder nach dem Aufstreichen des Bindemittels auf die Metalloberfläche, jedoch noch vor dessen Trocknung, erfolgen kann. Durch das Vorhandensein der Kautschukteile 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 An-" rauhen, 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 Kautschukteile enthaltenden Bindemasse zu versehen. Auf diese wird der Kautschul@ oder Kautschukersatzstoff aufgelegt. Die Vulkanisation erfolgt dann nach dem 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 Gewichtsprozente gemahlene, vulkanisierte IC-autschukabfälle zugesetzt sind, z. B. durch Tauchen, Spritzen oder Streichen überzogen. Nach dem Trocknen wird die Lösung einer unvulkanisierten Kautschukmischung aufgetragen, auf die trockene, raube 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 of joining rubber or rubber substitutes with metal using amorphous parts Binder with the label that rubber is used as an amorphous component will. Rubber includes all known types of rubber, such as. B. raw rubber, vulcanized rubber, waste rubber, synthetic rubber and rubber-like rubber Plastics, understand. The known can also be used in the rubber in a customary manner Additives and fillers may be included. The rubber becomes appropriate to the binder added in crumbs or as dust, which can also be done before or after the Binder on the metal surface, but before it dries can. Due to the presence of the rubber parts in amorphous form within the A significant increase in the surface area of the binding surface is achieved by using the binding agent, so that the binding capacity increases in the same way. Essential is that a preparation of the metal surface, e.g. B. the roughening, now superfluous, so that the new binding method by its simplicity and is therefore particularly economical. It's just a simple one Work step necessary to the metal surface with which the amorphous rubber parts containing binder. The Kautschul @ or rubber substitute is applied to this hung up. The vulcanization then takes place according to that for the respective rubber article eligible procedures. The bond between metal and rubber is perfect flawless and withstands all tensile and shear stresses. Embodiment Degreased, roughened metal parts are treated with a solution of 10 parts chlorinated rubber in 100 parts of toluene, which is 15 percent by weight of ground, vulcanized IC rubber waste are added, e.g. B. coated by dipping, spraying or brushing. After this Drying is applied to the solution of an unvulcanized rubber mixture The rubber mixture to be fastened is applied to the dry, rough surface and vulcanized in a known way.- It is also possible to use the ground waste to be added to the chlorinated rubber and rubber solution at the same time.
