Aufgabe der Erfindung ist es ein Erzeugnis der eingangs genannten Art dahingehend zu verbessern, daß eine Zusammensetzung mit verbesserten Materialeigenschaften zur Verfügung gestellt ist.task According to the invention, it is a product of the type mentioned in the introduction to improve that one Composition provided with improved material properties is.
Diese Aufgabe wird erfindungsgemäß durch ein Erzeugnis nach dem unabhängigen Anspruch 1 und dem nebengeordneten Anspruch 2 gelöst.These The object is achieved by a Product after the independent Claim 1 and the independent claim 2 solved.
Die Erfindung umfaßt den Gedanken, daß ein Erzeugnis aus einer thermoplastischen Elastomeren (TPE) ähnlichen Zusammensetzung (Compound) ist, bei der Gummimehl mit mindestens einem Thermoplasten und einem oder mehreren Vernetzungsmitteln im Prozeß des Schmelzmischens verarbeitet ist, wobei die Zusammensetzung einen Anteil an SEBS (Styrol-Ethylen-Butylen-Styrol) oder PP/EPDM (Polypropylen/Ethylen-Propylen-Dien-Kautschuk) enthält. Es hat sich überraschender Weise gezeigt, daß mit Hilfe des Zusatzes von SEBS oder PP/EPDM Zusammensetzungen (Compounds) herstellbar sind, die im Vergleich zu den bekannten Zusammensetzungen weicher sind. Die weichere Materialausbildung vergrößert die Möglichkeiten für die Verwendung der aus der Zusammensetzung hergestellten Erzeugnisse. Darüber hinaus wurde festgestellt, daß bei der Zusammensetzung eine unangenehme Geruchsausbildung vermindert oder sogar vollständig beseitigt ist.The Invention the thought that one Product of a thermoplastic elastomer (TPE) similar Composition (compound) is at the rubber flour with at least a thermoplastic and one or more crosslinking agents in the Process of Melt blending is processed, the composition of a Proportion of SEBS (styrene-ethylene-butylene-styrene) or PP / EPDM (polypropylene / ethylene-propylene-diene rubber) contains. It has become surprising shown that with Help the addition of SEBS or PP / EPDM compositions (compounds) produced are softer compared to the known compositions are. The softer material training increases the possibilities for use the products made from the composition. Furthermore was found at the composition reduces an unpleasant odor formation or even completely eliminated.
Es kann vorgesehen sein, daß das Gemisch von Gummimehl mit dem mindestens einen Thermoplasten und dem einen oder den mehreren Vernetzungsmitteln SEBS oder PP/EPDM als Füllstoff zugegeben ist. Des weiteren kann eine Weiterbildung vorsehen, daß SEBS oder PP/EPDM dem Gemisch von Gummimehl mit dem mindestens einen Thermoplasten und dem einen oder den mehreren Vernetzungsmitteln zugegeben ist.It can be provided that the Mixture of rubber powder with the at least one thermoplastic and the one or more crosslinking agents SEBS or PP / EPDM as a filler is added. Furthermore, a further development can provide that SEBS or PP / EPDM the mixture of rubber powder with the at least one thermoplastic and the one or more crosslinking agents.
SEBS oder PP/EPDM können in vollvernetzer, teilvernetzter oder nichtvernetzter Ausbildung verwendet sein.SEBS or PP / EPDM used in fully crosslinked, partially crosslinked or non-crosslinked training be.
Es hat sich gezeigt, daß als Thermoplast für die Mischung mit dem Gummimehl zum Ausbilden einer Thermoplast-Matrix ein weichgemachtes Polypropylen verwendet werden kann, insbesondere ein Reaktorpolypropylen.It has been shown that as Thermoplastic for the Mixture with the rubber dust to form a thermoplastic matrix a plasticized polypropylene can be used, in particular a reactor polypropylene.
Es kann vorgesehen sein, daß beim Verarbeiten ein Polyolefin-Elastomer zugegeben ist.It can be provided that the Processing a polyolefin elastomer is added.
Beim Herstellen der Zusammensetzung können SEES und/oder PP/EPDM je nach Anwendungsfall mit unterschiedlicher Härte und in unterschiedlicher Konzentration verwendet werden. Bei der Verwendung des weichlgemachten Polypropylens kann auch dieses in Abhängigkeit vom Anwendungsfall in unterschiedlicher Härte genutzt werden, um das Matrixmaterial für das Gummimehl zu bilden.When preparing the composition kön Depending on the application, SEES and / or PP / EPDM can be used with different hardness and in different concentrations. In the case of the use of the plasticized polypropylene, this too can be used to different hardness depending on the application, in order to form the matrix material for the rubber powder.
Die Zugabemengen von SEBS, PP/EPDM, dem weichgemachten Polypropylen und/oder dem Polyolefin-Elastomer im Rahmen des Compoundierprozesses können in Abhängigkeit von den gewünschten Eigenschaften der hergestellten Zusammensetzung individuell gewählt werden. Bei dem Polyolefin-Elastomer kann es sich beispielsweise um eine Verbindung auf Basis von Ethylen-Butene handeln.The Addition amounts of SEBS, PP / EPDM, the plasticized polypropylene and / or the polyolefin elastomer in the context of the compounding process can dependent on from the desired ones Properties of the composition produced are chosen individually. The polyolefin elastomer may be, for example, a Acting compound based on ethylene butenes.
Als Gummimehl wird bevorzugt ein Gummimehl aus Alt- oder Abfallgummi, beispielsweise aus Altreifen verwendet.When Rubber dust is preferably a rubber dust from waste or old gum, used for example from old tires.
Die in der vorstehenden Beschreibung und den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung in ihren verschiedenen Ausführungsformen von Bedeutung sein.The in the foregoing description and in the claims disclosed features of Invention can both individually and in any combination for the realization of the invention in its various embodiments of importance.
