PATENTANSPRÜCHE
1. Verfahren zur Herstellung eines Bauelementes, dadurch gekennzeichnet, dass man Abfallmaterial aus Kunststoff, herrührend von der Kabelindustrie und der Teppichherstellung und verarbeitung in Granulat- bis Pulverform zerteilt, mit Zement, expandiertem Perlit und einem Kunststoff- Bindemittel vermischt und dieses Gemisch mit Wasser versetzt und zum Aushärten bringt.
2. Verfahren nach Patentanspruch 1, dadurch gekennzeichnet, dass das Aushärten in einer Pressform unter Druck erfolgt.
3. Verfahren nach Patentanspruch 1, dadurch gekennzeichnet, dass zur Beschleunigung des Aushärtens eine Wärmebehandlung, vorzugsweise durch Dampf, vorgenommen wird.
4. Bauelement hergestellt nach dem Verfahren gemäss Patentanspruch 1, dadurch gekennzeichnet, dass es als Formstück ausgebildet ist.
Die Erfindung betrifft die Herstellung von Bauelementen unter weitgehender Verwertung von Kunststoff- Abfällen, wie sie in riesigen Mengen bei der Kabelindustrie und bei der Herstellung und Verarbeitung von Teppichen, insbesondere bei der Verlegung von Spannteppichen, anfallen.
Die wesentlichen Merkmale der Erfindung ergeben sich aus dem Patentanspruch 1. Nachfolgend werden rein beispielsweise Ausführungsmöglichkeiten der Erfindung beschrieben.
Zur Herstellung wird Abfallmaterial von der Kabelindustrie, insbesondere solches, welches bei der Ausschlachtung von elektrischen Apparaten und Geräten nach Entfernen der Metallteile anfällt zu einem Granulat oder Pulver verarbeitet. Das gleiche geschieht mit Abfällen, welche bei der Herstellung und Verarbeitung von Kunststoff- Teppichen entstehen. Es ist klar, dass im Bedarfsfall zusätzlich auch andere Kunststoffmaterialabfälle verwendet werden können. Die je nach dem vorgesehenen Verwendungszweck zu einem Pulver oder Granulat verarbeiteten Kunststoffabfälle werden mit Zement, expandiertem feinkörnigem Perlit und einem Kunststoff- Bindemittel, z.B. Sigma, evtl. noch unter Zugabe von Kalk, gemischt. Die Mischung wird mit Wasser angerührt und nach gewünschter Formgebung ausgehärtet.
Je nach den gewünschten Eigenschaften des herzustellenden Bauelementes, wie Wärmeisolation, mechanische Festigkeit und spezifisches Gewicht, kann das Aushärten in einer Form ohne oder unter Anwendung eines mehr oder weniger grossen Druckes erfolgen. Durch Wahl der Korngrösse der Ausgangsmaterialien lassen sich die genannten Eigenschaften zusätzlich beeinflussen. Die Aushärtezeit kann durch Anwendung von Wärme beeinflusst werden.
Die Art der Bauelemente, die mit dem Verfahren hergestellt werden können, ist ausserordentlich gross. Beispielsweise können Platten als Ersatz für die nicht mehr beliebten Eternitplatten, Isolierplatten, Estrichböden usw., sowie grössere Formkörper, wie z. B. Badewannen hergestellt werden.
Die nach dem Verfahren hergestellten Bauelemente besitzen weitere bei der Anwendung vorteilhafte Eigenschaften, man kann sie sägen, Nägel und Schrauben direkt anbringen und ausserdem sind sie praktisch unbrennbar.

PATENT CLAIMS
1. A method for producing a component, characterized in that waste material made of plastic, originating from the cable industry and carpet manufacture and processing in granular to powder form, mixed with cement, expanded pearlite and a plastic binder and mixed with water and cures.
2. The method according to claim 1, characterized in that the curing takes place in a press mold under pressure.
3. The method according to claim 1, characterized in that a heat treatment, preferably by steam, is carried out to accelerate the curing.
4. Component manufactured by the method according to claim 1, characterized in that it is designed as a fitting.
The invention relates to the production of components with extensive recycling of plastic waste, as they occur in huge quantities in the cable industry and in the manufacture and processing of carpets, especially in the laying of carpets.
The essential features of the invention result from patent claim 1. In the following, purely exemplary embodiments of the invention are described.
For the production, waste material is processed by the cable industry, in particular that which is obtained when electrical apparatus and equipment are slaughtered after the metal parts have been removed to form a granulate or powder. The same happens with waste, which arises in the manufacture and processing of plastic carpets. It is clear that other plastic material waste can also be used if necessary. The plastic waste processed into a powder or granulate depending on the intended use is mixed with cement, expanded fine-grain pearlite and a plastic binder, e.g. Sigma, possibly with the addition of lime, mixed. The mixture is mixed with water and cured according to the desired shape.
Depending on the desired properties of the component to be manufactured, such as thermal insulation, mechanical strength and specific weight, curing can take place in a mold without or using a more or less high pressure. The properties mentioned can also be influenced by choosing the grain size of the starting materials. The curing time can be influenced by applying heat.
The type of components that can be produced with the method is extremely large. For example, plates as a replacement for the no longer popular Eternit plates, insulating plates, screed floors, etc., as well as larger moldings, such as. B. Bathtubs are made.
The components produced by the process have other advantageous properties in use, they can be sawn, nails and screws attached directly and, moreover, they are practically non-flammable.
