BeschreibungDescription
In weiten Bereichen der verarbeitenden Industrie und im Handwerk fallen Materialien an, für die es bisher keine Wiederverwertung und/oder Rückführung gibt. Diesemüssen in der Regel aufwendig entsorgt werden, was auch ökologisch oft problematisch ist.In many areas of the manufacturing industry and in the craft sector, materials are generated for which there is currently no recycling and/or return. These usually have to be disposed of in a complex manner, which is often ecologically problematic.
Pulverlacke sind Beschichtungspulver, die nach dem Auftragen und Aufschmelzen auf einen Untergrund, insbesondere metallischer Natur, eine Lackierung ergeben.Powder coatings are coating powders which, when applied and melted onto a substrate, especially a metallic one, produce a coating.
Pulverlacke sind thermoplastische oder duromere Kunststoffe. Zur duroplastischen Pulverlackbeschxchtung eignen sich insbesondere Epoxidharze, Polyester und Acrylharze, während beim sogenannten Wirbelsintern thermoplastische Kunststoffe, wie Polyethylenpulver, Polyvinylchloridpulver, Polyamidpulver, chloriertePowder coatings are thermoplastic or thermosetting plastics. Epoxy resins, polyester and acrylic resins are particularly suitable for thermosetting powder coatings, while so-called fluidized bed sintering uses thermoplastic plastics such as polyethylene powder, polyvinyl chloride powder, polyamide powder, chlorinated

Polyether verwendet werden. Die Besonderheit bei Pulverlacken ist ihre Eigenschaft wärmehärtbar zu sein.Polyether can be used. The special feature of powder coatings is their ability to be heat-cured.
Die Pulverbeschichtung auf der Basis von Pulverlacken ermöglicht eine weitgehend automatisierte Arbeitsweise, ist wegen der Abwesenheit von Lösungsmitteln umweltfreundlich und findet daher im steigenden Ausmaß bei der Herstellung von beispielsweise Autoteilen, Haushaltsgegenständen und in der Möbelindustrie Anwendung. Die Hersteller von Pulverlacken stehen vor dem Problem, die Pulver immer mit bestimmten Korngrößenverteilungen anzubieten. Im Verlaufe des Herstellungsprozesses läßt es sich nicht vermeiden, daß außerhalb dieser vorgegebenen Korngrößenverteilungen weitere Größen an Pulvern entstehen, die sich für viele Beschichtungsverfahren nicht mehr verwenden lassen. Diese aus den gesetzten Normen herausfallenden Korngrößenzusammensetzungen von Pulverlacken fallen als Abfall an. Weiterhin entstehen große Abfallmengen bzw. Reststoffe bei der Pulverbeschichtung, die sich nicht als Beschichtungslacke verwenden lassen.Powder coating based on powder paints enables a largely automated process, is environmentally friendly due to the absence of solvents and is therefore increasingly used in the manufacture of, for example, car parts, household items and in the furniture industry. Manufacturers of powder paints are faced with the problem of always offering powders with specific grain size distributions. During the manufacturing process, it is unavoidable that other sizes of powder arise outside of these specified grain size distributions that can no longer be used for many coating processes. These grain size compositions of powder paints that fall outside the set standards are generated as waste. Furthermore, large quantities of waste or residual materials arise during powder coating that cannot be used as coating paints.
Ebenso fallen in der holzverarbeitenden und , papierverareitenden Industrie und im Handwerk enorme Mengen an nicht weiter verwendungsfähigem Holz bzw. Papier an.Hinzu kommt, daß viel Holz und Papier .einer Wiederverwertung zugeführt werden muß und daß die Kapazitäten für die Wiederverwendung häufig bereits voll ausgelastet sind, so daß große Mengen von Holz und Papier auf Mülldeponien enden. Weitere nicht verwendbare Materialien fallen beispielsweise in der Glasindustrie an, in der Regel kann ein Teil des Glases wieder eingeschmolzen werden. Fallen jedoch Glasbruchgemische an, kann diese Art der Wiederverwertung problematisch sein, insbesondere wenn der Glasbruch korngrößenmäßig in den unteren Bereichen liegt.Enormous amounts of unusable wood and paper are also generated in the wood and paper processing industries and in the craft sector. In addition, a lot of wood and paper has to be recycled and the capacity for recycling is often already at full capacity, meaning that large amounts of wood and paper end up in landfills. Other unusable materials are generated in the glass industry, for example; some of the glass can usually be melted down again. However, if a mixture of broken glass is generated, this type of recycling can be problematic, especially if the broken glass is in the lower range in terms of grain size.

Die Liste von Abfallmaterialien, die im Verlaufe eines Herstellungs- oder Bearbeitungsprozesses entstehen, für die es keine Weiterverwendung gibt, außer die, auf einer Mülldeponie zu landen, kann weitergeführt werden.The list of waste materials generated during a manufacturing or processing process for which there is no further use other than to end up in a landfill can be continued.
Der Erfindung liegt nun die Aufgabe zugrunde, aus körnigem oder pulverförmigen Abfallmaterialien oder Reststoffen Formkörper zu schaffen, deren physikalische Eigenschaften sich in weiten Grenzen variieren lassen.The invention is based on the object of creating molded bodies from granular or powdered waste materials or residues, the physical properties of which can be varied within wide limits.
Die Lösung der Aufgabe erfolgt mit einem Formkörper, der aus einer Mischung von Pulverlacken unterschiedlicher oder gleicher Körnungen mit Füllstoffen unterschiedlicher oder gleicher Körnungen besteht.The task is solved with a molded body that consists of a mixture of powder coatings of different or the same grain sizes with fillers of different or the same grain sizes.
Aus diesen Formkörpern kann man die unterschiedlichsten Produkte für den täglichen oder industriellen Bedarf, insbesondere in der Bau- und Möbelindustrie herstellen.These molded bodies can be used to produce a wide variety of products for everyday or industrial use, especially in the construction and furniture industries.
Dadurch, daß es möglich ist, im wesentlichen nur Abfallmaterialien für die Herstellung dieser Formkörper einzusetzen, sind diese Formkörper auch sehr kostengünstig herzustellen. Bei der Herstellung dieser Formkörper wird die Eigenschaft von Pulverlacken ausgenutzt bei einer Temperaturbehandlung zusammenzufließen, und dadurch die Funktion eines Bindemittels zu übernehmen. In dieses Bindemittel eingelagert sind vorteilhafterweise erfindungsgemäß holzartige und zelluloseartige Materialien, aber auch weitere anorganische Füllstoffe und polymere Stoffe, die bei industrieller Verarbeitung oder im Handwerk als Abfallprodukte oder Reststoffe anfallen. Durch Schaffung dieser Formkörper ist es möglich zu verhindern, daß diese Materialien auf Mülldeponien oder auch in Müllverbrennungsanlagen landen.Because it is possible to use essentially only waste materials for the production of these molded bodies, these molded bodies can also be produced very cost-effectively. In the production of these molded bodies, the property of powder coatings to flow together during a heat treatment is exploited, thereby taking on the function of a binding agent. According to the invention, wood-like and cellulose-like materials are advantageously embedded in this binding agent, as are other inorganic fillers and polymeric substances that arise as waste products or residues during industrial processing or in handicrafts. By creating these molded bodies, it is possible to prevent these materials from ending up in landfills or in waste incineration plants.
Materialien auf Mülldeponien oder auch in Müllverbrennungsanlagen landen.Materials end up in landfills or waste incineration plants.
Die Herstellung eines erfindungsgemäßen Formkörpers ist unproblematisch. Die Ausgangsmaterialien mit einer entsprechend vorgegebenen Korngröße werden trocken miteinander vermischt und anschließend einem Brennprozeß ausgesetzt. Hierbei schmilzt der Pulverlack und bildet eine Matrix, in die die lignin- und zellulosehaltigen Teilchen bzw. anorganische Füllstoffe eingelagert sind. Durch das vorherige Festlegen bestimmter Korngrößenverteilungen der Füllstoffe ist es möglich, die Dichte des Formkörpers von vornherein zu optimieren. Durch Wahl bestimmter Korngrößenverteilungen lassen sich auch die Schrumpfungsprozesse günstig beeinflussen. Gegebenenfalls wäre es zur Verbesserung des Schrumpfungsverhaltens sinnvoll, Füllstoffe anorganischer Natur wie z.B. Glas der Mi s chung zuzuführen.The production of a molded body according to the invention is unproblematic. The starting materials with a correspondingly specified grain size are mixed together dry and then subjected to a firing process. The powder coating melts and forms a matrix in which the lignin and cellulose-containing particles or inorganic fillers are embedded. By previously determining certain grain size distributions of the fillers, it is possible to optimize the density of the molded body from the outset. By choosing certain grain size distributions, the shrinkage processes can also be influenced favorably. If necessary, it would be useful to add inorganic fillers such as glass to the mixture in order to improve the shrinkage behavior.
Die Farbgebung der erfindungsgemäßen Formkörper läßt sich durch Auswahl bestimmter Pulverlackabfälle oder durch weiteres Zumischen von Farbpigmenten regeln.The coloring of the molded articles according to the invention can be regulated by selecting certain powder coating waste or by further mixing in color pigments.
Eigenschaften wie Dichte und Oberflächenstruktur sowie Festigkeit sind durch die Art zusätzlicher Füllstoffe bzw. durch die Verwendung zusätzlicher polymerer Materialien in weiten Grenzen variierbar.Properties such as density and surface structure as well as strength can be varied within wide limits by the type of additional fillers or by the use of additional polymer materials.
Da die trockenen Mischungen sich praktisch in jede Form bringen lassen, ist der Formenreichtum dieser Formkörper unbegrenzt. Durch das Einbringen von wasserlöslichen Verbindungen mit körniger Struktur beispielsweise kristalline, salzartige Teilchen ist es möglich, nach dem Brennprozeß durch eine Wasserbehandlung diese Verbindung herauszulösen und dadurch einen porösen Formkörper zuSince the dry mixtures can be made into practically any shape, the variety of shapes of these molded bodies is unlimited. By introducing water-soluble compounds with a grainy structure, for example crystalline, salt-like particles, it is possible to dissolve this compound after the firing process by treating it with water, thereby creating a porous molded body.
