Description

Die Erfindung betrifft Altpapierextrudate für unterschiedliche Anwendungszwecke, insbesondere im Baugewerbe, in der Landwirt­ schaft, im Gartenbau sowie in der Verpackungsindustrie. Die Produkte sind applikationsabhängig recyclefähig bzw. biologisch abbaubar.The invention relates to waste paper extrudates for different Applications, especially in the construction industry, in the farmer in horticulture and the packaging industry. the Depending on the application, products are recyclable or biological degradable.

Allen bisher bekannten Verfahren zur Herstellung und Applikation von Extrudaten aus Zellulosefasern in Form von reiner Zellulose, Holzschliff oder Altpapier, gegebenenfalls gemeinsam mit tierischen und/oder pflanzlichen Proteinen und/oder Stärke ist die Verwendung der in der Kunststoffindustrie üblichen Extrusi­ onstechnik gemeinsam.All previously known methods of manufacture and application of extrudates made from cellulose fibers in the form of pure cellulose, Wood pulp or waste paper, possibly together with animal and / or vegetable proteins and / or starch the use of the extrusions common in the plastics industry ontechnology together.

Erstmals wird die Anwendung der aus der Kunststoffindustrie bekannten Extrusionstechnik zur Herstellung von Gegenständen aus Pappe in der SE-PS 78 056 934 (DE 29 20 988) beschrieben. Ziel dieser Erfindung war es, den hohen Wassergehalt bei der Erzeugung einer ausreichenden Anzahl von Wasserstoffbrückenbin­ dungen im Endprodukt durch Zugabe eines Hydrokolloids derart zu senken, daß das Wasser der Wasserdispersion vollständig gebunden ist. Dadurch war es möglich, daß die erhaltene Paste durch Extru­ dieren, Spritzgießen, Beschichten, Walzen, Pressen und/oder Ziehen zu dem Gegenstand aus Pappe geformt wird. Als Hydrokollo­ ide werden nur Stärke, Stärkederivate, Dextrine, Polyvinylalko­ hol, Cellulosederivate, tierische und pflanzliche Proteine, pflanzliche Gummi, synthetische Hydrokolloide sowie Getreide- oder Knollenmehle genannt.For the first time, the application is from the plastics industry known extrusion technology for the production of objects Cardboard is described in SE-PS 78 056 934 (DE 29 20 988). target this invention was to reduce the high water content in the Creation of a sufficient number of hydrogen bonds Applications in the end product by adding a hydrocolloid in such a way lower that the water of the water dispersion is completely bound is. This made it possible that the paste obtained by extrusion dating, injection molding, coating, rolling, pressing and / or Pulling to form the cardboard article. As a hydrocollo ide are only starch, starch derivatives, dextrins, polyvinyl alcohol hol, cellulose derivatives, animal and vegetable proteins, vegetable gums, synthetic hydrocolloids and grain or called tuber meal.

In der US-PS 4 123 489 wird eine Methode zur Konversion von Altpapier in verwertbare Formen detailliert beschrieben. Es kann sowohl gehacktes als auch gemahlenes Altpapier verwendet werden, wobei die Endprodukte Anwendung als Pflanzenmulchmaterial, Dün­ ger, Brennstoff, Tierfutter und Aggregationshilfsmittel fin­ den. Als plastifizierbare Zuschlagstoffe werden Futterpflanzen, die für die Tierernährung verwendet werden, eingesetzt.In US Pat. No. 4,123,489, a method for converting Waste paper described in detail in usable forms. It can both chopped and ground waste paper are used, the end products being used as plant mulch material, dune ger, fuel, animal feed and aggregation aids fin the. Forage plants, used for animal nutrition.

Eine Vielzahl von Erfindungen zu biologisch unbedenklichen Bau­ stoffen beinhaltet die Zumischung von Altpapier als "Strukturkör­ per" zu Zement, Gips, Kalksandstein u. a. (DE 36 11 080, DE 35 23 115, DE 37 20 134, DE 37 34 729, US 4 123 489, DD 242 218), mit dem Vorteil erhöhter Biegefestigkeit und der Verwertung eines billigen Rohstoffes. Nachteilig für viele Einsatzgebiete ist die erreichbare Dichte des Endproduktes, die es z. B. als Dämm- und Isolierstoff oder als Füllmaterial schlecht geeignet sein läßt. Die Extrusion von Altpapier in Verbindung mit plastifizierbarer Stärke (DE 34 20 195) gleicht diesen Nachteil wieder aus, jedoch sinken diese Extrudate, insbesondere bei vertikaler Schüttung in relativ kurzer Zeit wieder zusammen. A multitude of inventions for biologically harmless construction materials includes the admixture of waste paper as "structure grain" per "to cement, gypsum, sand-lime brick and others (DE 36 11 080, DE 35 23 115, DE 37 20 134, DE 37 34 729, US 4 123 489, DD 242 218), with the advantage of increased flexural strength and the utilization of a cheap raw material. This is a disadvantage for many areas of application achievable density of the end product, which it z. B. as insulation and Insulating material or can be poorly suited as a filler material. The extrusion of waste paper in connection with plasticizable Starch (DE 34 20 195) compensates for this disadvantage, however These extrudates sink, especially when poured vertically into together again in a relatively short time.

In der DE-PS 38 33 178 ist ein Papierschaum-Granulat näher erläu­ tert, das durch Extrusion von Altpapier und Biopolymeren, wie Stärke, Stärkederivate, Dextrine, Zellulosederivate, tierische und pflanzliche Proteine, pflanzliche Gummi, synthetische Hydro­ kolloide sowie Getreide- oder Knollenmehle, versetzt mit Dünger­ konzentrat, hergestellt wird. Das Granulat läßt sich auch als Trägermaterial zum "Verkapseln" von Saatgut durch Eindrücken der Samenkörner verwenden. Die Zerfallszeit kann man lt. PS 38 33 178 durch dosierte Hinzugabe von Altpapier (u. a.) so steuern, daß sich unterschiedliche Düngezeiträume ergeben.In DE-PS 38 33 178 a paper foam granulate is explained in more detail tert, made by extrusion of waste paper and biopolymers, such as Starch, starch derivatives, dextrins, cellulose derivatives, animal and vegetable proteins, vegetable gums, synthetic hydro colloidal as well as cereal or tuber flours, mixed with fertilizer concentrate. The granules can also be used as Carrier material for "encapsulating" seeds by pressing in the Use seeds. The disintegration time can be determined according to PS 38 33 178 control through the dosed addition of waste paper (among other things) so that different fertilization periods result.

Der Nachteil dieses Verfahrens ist die zu kurze Verweilzeit im Boden und vor allem der rapide Strukturverlust. Damit ist das Produkt nur unzureichend als Mulchmaterial mit gleichzeitigem Düngeeffekt nutzbar.The disadvantage of this process is the too short residence time in the Soil and above all the rapid structural loss. So that's that Product is insufficient as a mulch material with simultaneous Fertilizing effect can be used.

Die Aufgabe der Erfindung ist es, kostengünstige, recyclefähige bzw. biologisch abbaubare Altpapierextrudate mit hohen Standzei­ ten für einen weiten Einsatzbereich in Industrie, Landwirtschaft und Gartenbau zu entwickeln.The object of the invention is to provide inexpensive, recyclable or biodegradable waste paper extrudates with high durability for a wide range of applications in industry and agriculture and develop horticulture.
