Description

Die Erfindung betrifft einen Formkörper für elastische Beläge, bestehend aus Mischungen von zerkleinertem Recyclingmaterial und geeigneten Bindemitteln.The invention relates to a molded body for elastic Coverings consisting of mixtures of crushed Recycled material and suitable binders.

Die Verarbeitung von Recyclingmaterial aus Neugummiabfällen, aus Altgummi insbesondere Altreifen, sowie aus Polyurethanhartschaum und ähnlichen Abfällen zu Produkten unterschiedlicher Einsatzmöglichkeiten ist seit längerer Zeit bekannt.Processing of recycling material New rubber waste, from waste rubber, in particular waste tires, and from rigid polyurethane foam and similar waste to products of different uses known for a long time.

Die DE-PS 17 20 059 beschreibt beispielsweise die Herstellung von Formkörpern aus zerkleinertem bzw. gemahlenem, kompakten Altgummi unter Zusatz von Bindemitteln. Bei den Formköpern handelt es sich um einschichtige, plattenförmige Körper, die durch weitere Arbeitsgänge, wie Schneiden, Fräsen und/oder Schälen in die endgültige Form gebracht werden, und die gegebenenfalls mindestens einseitig mit einer Folie oder einer PVC-Abdeckung bzw. Ummantelung versehen sind. Die elastischen Körper sind auch bei Bedarf mit einer als Drahtskelett ausgebildeten Versteifungseinlage versehen.DE-PS 17 20 059 describes, for example Production of molded articles from comminuted or ground, compact waste rubber with the addition of Binders. The shaped bodies are single-layer, plate-shaped body, which is characterized by further Operations such as cutting, milling and / or peeling in the final shape will be brought, and the if necessary at least on one side with a film or a PVC cover or casing. The elastic bodies are also available with an as needed Wire skeleton provided stiffening insert.

Aus der EP-OS 01 35 595 ist die Herstellung eines Boden- oder dergleichen Belages als ein- oder mehrschichtige Bahnenware aus zerkleinerten Gummiabfällen und/oder Gummigranulat aus Neu- oder Altgummi und Bindemittel bekannt. Die Bahnen sind fallweise mit einem Textilteppich, mit Polyurethanbeschichtungen oder mit einem textilen Gewebe als Ober- und Unterbelag versehen und weisen beidseitig ebene Oberflächen auf.From EP-OS 01 35 595 is the manufacture of a floor or the same covering as a single or multi-layer Sheets of shredded rubber waste and / or Granulate from new or old rubber and binder known. The tracks are occasionally with one  Textile carpet, with polyurethane coatings or with a textile fabric as top and bottom covering and have flat surfaces on both sides.

Die bekannten Formkörper und Bahnenwaren sind vornehmlich plattenartig mit beidseitig ebenen Begrenzungsflächen ausgebildet. Sie sind, auch bei mehrschichtigem Aufbau, abgesehen von gitterartigen Versteifungseinlagen und textilen Ober- und Unterbelägen jeweils nur aus einer gleichartig zusammengesetzten Mischung hergestellt. Die sich daraus ergebenden Nachteile bestehen insbesondere darin, daß unter den verlegten glatten Belägen keine Luftzirkulation stattfindet und auf den Unterbauten sich ansammelnde Feuchtigkeit nicht abtrocknet. Außerdem bewegen sich die angestrebten Eigenschaften, wie Elastizität, Verschleißfestigkeit, Stabilität und Festigkeit des Formkörpers nur in engen Grenzen.The known moldings and sheet goods are primarily plate-like with flat boundary surfaces on both sides educated. They are, even with a multilayer structure, apart from lattice reinforcements and textile top and bottom coverings only from one mixture of the same composition. The resulting disadvantages exist in particular in the fact that none of the laid smooth coverings Air circulation takes place and on the substructures themselves accumulating moisture does not dry out. Furthermore move the desired properties, like Elasticity, wear resistance, stability and Strength of the molded body only within narrow limits.

Der Erfindung liegt die Aufgabe zugrunde, einen preisgünstigen Formkörper aus Recyclingmaterial, aus granuliertem und/oder zerschnitzeltem Neu- bzw. Altgummi, z. B. aus der Altreifenaufarbeitung sowie gegebenenfalls anderen elastischen Stoffen aus der Kunststoffindustrie in Verbindung mit geeigneten Bindemitteln bereitzustellen, der aufgrund seines besonderen Aufbaues und seiner Ausbildung vielfältige Einsatzgebiete hat, ein qualitativ hochwertiges Produkt darstellt und dessen Eigenschaften optimal auf seine Verwendung abgestimmt sind.The invention has for its object a inexpensive molded body made from recycling material granulated and / or shredded new or old rubber, e.g. B. from the reconditioning of old tires and, if necessary other elastic materials from the plastics industry in combination with suitable binders to provide, due to its special structure and its training has a wide range of uses represents high quality product and its Properties optimally matched to its use are.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Formkörper drei übereinander angeordnete, verdichtete Schichten mit gleichmäßiger Schichtstärke aufweist, die an den Grenzflächen fest miteinander verbunden sind, wobei die obere Deckschicht und die mittlere Schicht plattenförmig ausgebildet sind, und die untere Schicht zu höckerartigen, durch Einschnitte voneinander getrennten Füßen ausgestaltet ist.This object is achieved in that the molded body three, one above the other, compressed Has layers with a uniform layer thickness that  are firmly connected at the interfaces, with the top cover layer and the middle layer are plate-shaped, and the lower layer bump-like, separated by incisions Feet.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, daß die Schichten aus verschiedenartigen Mischungen bestehen.According to an advantageous embodiment of the invention provided that the layers of different types Mixtures exist.

Als vorteilhaft hat sich außerdem gezeigt, daß die Schichten unterschiedliche Körnungen aufweisen.It has also been shown to be advantageous that the Layers of different grain sizes.

Erfindungsgemaß ist es weiterhin vorteilhaft, wenn die Schichten unterschiedliche Raumgewichte aufweisen.According to the invention, it is also advantageous if the Layers have different densities.

Der erfindungsgemäße Formkörper hat gegenüber den bekannten Formkörpern und Bahnen den erheblichen Vorteil, daß durch den mehrschichtigen Aufbau aus verschiedenartigen Mischungen und die unterschiedlichen Körnungen der einzelnen Schichten die elastischen Eigenschaften des Formkörpers sich seinem vorgesehenen Einsatz anpassen lassen und die Verschleißfestigkeit der Deckschicht auf die auftretenden Belastungen abstimmbar ist, und daß schließlich durch die erfindungsgemäße Ausbildung der unteren Schicht als höckerartige Füße ein ausgezeichneter Drainageeffekt der elastischen Beläge erzielt wird.The molded body according to the invention has the known shaped bodies and sheets the considerable advantage that from the multilayer structure different mixtures and the different Grain of the individual layers the elastic Properties of the molded body are its intended Have the insert adjusted and the wear resistance of the Top layer can be matched to the loads that occur is, and that finally by the invention Formation of the lower layer as a bumpy feet excellent drainage effect of the elastic coverings is achieved.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels, das in der Zeichnung dargestellt ist, näher beschrieben. The invention is based on a Embodiment that shown in the drawing is described in more detail.  

Die Figur zeigt einen erfindungsgemäßen Formkörper in perspektivischer Darstellung von unten gesehen. Der Formkörper 1 setzt sich aus drei übereinander angeordneten, gleichmäßig verdichteten Schichten 2, 3, 4 zusammen, die an ihren Grenzflächen 5, 6 fest miteinander verbunden sind. Die Schichten 2, 3, 4 weisen durchgehend gleiche Schichtstärken auf, wobei die Deckschicht 2 und die mittlere Schicht 3 plattenförmig ausgebildet sind. Die untere Schicht 4 ist zu höckerartigen Füßen 7 ausgestaltet, die durch grabenartige Einschnitte 8 voneinander getrennt sind.The figure shows a molded body according to the invention seen in perspective from below. The molded body 1 is composed of three, uniformly compressed layers 2 , 3 , 4 arranged one above the other, which are firmly connected to one another at their interfaces 5 , 6 . The layers 2 , 3 , 4 have the same layer thicknesses throughout, the cover layer 2 and the middle layer 3 being plate-shaped. The lower layer 4 is formed to bump-like feet 7 , which are separated from one another by trench-like incisions 8 .

Nach einem Ausführungsbeispiel der Erfindung ist vorgesehen, daß die Deckschicht 2 aus feingranuliertem Neugummi besteht. Dadurch wird für die Deckschicht 2, die je nach Verwendungszweck der Beläge unterschiedlich starken Belastungen ausgesetzt ist, eine gute Verschleißfestigkeit erreicht.According to an embodiment of the invention it is provided that the cover layer 2 consists of fine granulated new rubber. As a result, good wear resistance is achieved for the cover layer 2 , which is exposed to loads of different strengths depending on the purpose of the coverings.

Die mittlere Schicht 3 ist aus feingranuliertem Altgummi, beispielsweise aus Altreifen hergestellt. Die feine Körnung hat zwar eine geringe Elastizität der Schicht 2 zur Folge, bewirkt aber eine höhere Festigkeit und sorgt damit in vorteilhafter Weise für die Stabilität des Formkörpers 1.The middle layer 3 is made from finely granulated waste rubber, for example from waste tires. The fine grain size results in a low elasticity of the layer 2 , but brings about a higher strength and thus advantageously ensures the stability of the molded body 1 .

Mit der zu Füßen 7 ausgebildeten Schicht 4, die in der Regel etwas dicker ist als die beiden anderen Schichten 2, 3, ruht der Belag auf dem Unterboden bzw. der Unterlage. Diese Schicht 4 besteht erfindungsgemäß aus grobgranuliertem bzw. grobzerschnitzeltem Altgummi. Sie erhält durch ihren groben Aufbau eine größere Elastizität und übernimmt das Abfedern und Dämpfen stoßartig auftreffender Belastungen, beispielsweise bei Bodenbelägen für Freizeit- und Sportstätten sowie bei der Verwendung als Fallschutzmatten. Außerdem weist die grobstrukturierte Bodenfläche der Füße 7 eine gute Haftfestigkeit auf.With the layer 4 formed at the feet 7 , which is generally somewhat thicker than the other two layers 2 , 3 , the covering rests on the sub-floor or the underlay. According to the invention, this layer 4 consists of coarsely granulated or coarsely shredded waste rubber. Its rough structure gives it greater elasticity and it absorbs and dampens impacts that occur suddenly, for example for floor coverings for leisure and sports facilities and when used as fall protection mats. In addition, the roughly structured bottom surface of the feet 7 has good adhesive strength.

Die grabenartigen Einschnitte B zwischen den höckerartigen Füßen 7 erzeugen einen ausgezeichneten Drainageeffekt. Im Gegensatz zu den bekannten, aus plattenartigen Formkörpern hergestellten Bodenbelägen wird durch die erfindungsgemäße Ausbildung des Formkörpers 1 eine gezielte Ableitung von Flüssigkeiten, beispielsweise von Regenwasser bei Verwendung als Außenbeläge oder von Schmutzwasser oder sonstigen Flüssigkeiten in Naßräumen erreicht, so daß der Unterboden relativ rasch trocknet und Fäulnisbildung unter dem Bodenbelag vermieden wird.The trench-like incisions B between the bump-like feet 7 produce an excellent drainage effect. In contrast to the known, made of plate-like moldings floor coverings of the molded body 1 is achieved a targeted drainage of liquids, for example of rain water when used as outer coverings or dirty water or other liquids in wet rooms by the inventive design, so that the underbody relatively quickly dries and Rotting under the floor covering is avoided.

Ein weiterer Vorteil des erfindungsgemäß aufgebauten und ausgebildeten Formkörpers 1 liegt in seiner guten Schalldämmung. Daher eignen sich Beläge aus dem Formkörper 1 unter anderem auch als Wand- und Deckenverkleidungen sowie Bodenbelägen von Schießständen.Another advantage of the molded body 1 constructed and constructed according to the invention is its good sound insulation. Coverings from molded body 1 are therefore also suitable, inter alia, as wall and ceiling claddings and floor coverings for shooting ranges.

Neben beispielhaft aufgezeigten Einsatzmöglichkeiten des erfindungsgemäßen Formkörpers 1 sind weitere Verwendungsmöglichkeiten im Hoch- und Tiefbau, als Bauschutzmatten, sowie als Industriebeläge gegeben.In addition to the possible uses of the molded body 1 according to the invention, there are other possible uses in building construction and civil engineering, as building protection mats and as industrial coverings.
