Abstract

Recycled material (1) is shredded (4) and screened (5) producing granular material containing glass reinforcement fibers. A power mixer in an intermediate tank (8) mixes the granular material with binder from a storage vessel (8.1). Water is added to the mixture, producing a pasty mass. This is cast in a mold (10), immediately after water addition. The filled mold is sealed and a molding cover (11) compresses the contents by at least one third. The binder is a polyurethane resin. Based on the quantity of granular material present, the binder ratio is between 1 : 0.25 and 1 : 0.1. The panel produced, is a flat flooring panel of mean density 580 kg/m3>. A panel of the same density, is a wavy molding used for wall cladding. It has an angular, coarsely corrugated profile, having flat surfaces between pairs of inclined surfaces. The panels mean strength is at least 4000 kPa.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines plattenförmigen Baumaterials für Bauelemente oder dergleichen aus Abfallwertstoffen, wobei als Abfallwertstoff einseitig oder beidseitig mit glasfaserverstärkten Kunststoffauflagen, insbesondere mit glasfaserverstärkten Polyesterplatten beschichteten Dämmkernen aus Polyurethan-Hartschaum eingesetzt werden, und wobei die GFK-Platten insbesondere lackbeschichtet sind.The The invention relates to a method for producing a plate-shaped building material for components or the like from waste materials, wherein as waste value single-sided or double-sided with glass fiber reinforced plastic overlays, in particular with glass fiber reinforced Polyester plates coated Dämmkernen be used made of rigid polyurethane foam, and where the GRP plates especially lacquer-coated.

Ein- oder beidseitig mit glasfaserverstärkten Kunststoffauflagen, insbesondere mit glasfaserverstärkten Polyesterplatten beschichteten Dämmkernen aus Polyurethan-Hartschaum werden vielfältig eingesetzt, beispielsweise im Fahrzeugbau oder bei der Herstellung von Türen, die mit einer dämmenden Füllung versehen sind. Im Fahrzeugbau werden zur Innenauskleidung solche Platten nach dem Zuschnitt an Profile angeschraubt, für Haustüren werden sie entsprechend der Türgestaltung zugeschnitten und danach als Füllung in einen Ausschnitt eines Kunststoff- oder Aluminiumrahmens eingesetzt. Bei dieser Herstellung fal len Reststücke an, die der Entsorgung zugeführt werden müssen, da eine Wiederverwendbarkeit in der bestehenden Form nicht gegeben ist. Als äußerst problematisch gestalten sich hier die Entsorgungskosten, weil derartige verschnittene Platten letztendlich nur als Sondermüll gelten und entsprechend zu entsorgen sind.One- or on both sides with glass fiber reinforced plastic pads, in particular with glass fiber reinforced Polyester plates coated Dämmkernen made of rigid polyurethane foam are used in many ways, for example in vehicle construction or in the manufacture of doors provided with an insulating filling are. In vehicle construction, such panels are used for internal lining screwed to profiles after cutting, for house doors they are accordingly the door design cut and then as a filling used in a cutout of a plastic or aluminum frame. In this production fall on leftovers, which are supplied for disposal have to, because there is no reusability in the existing form is. As extremely problematic here form the disposal costs, because such blended In the end, plates are only considered hazardous waste and accordingly to be disposed of.

Hieraus ergibt sich die der Erfindung zugrunde liegende Aufgabe, ein Recyclingverfahren bereit zu stellen, mit dem derartige Türfüllungsplatten wieder als Wertstoff Verwendung finden.From this results from the object underlying the invention, a recycling process to provide, with such door panels again as recyclable material Find use.

Diese Aufgabe wird für ein gattungsgemäßes Verfahren durch die kennzeichnenden Merkmale des Hauptanspruchs gelöst: vorteilhafte Weiterbildungen des Verfahrens und bevorzugte Ausführungsformen ergeben sich aus den Unteransprüchen.These Task is for a generic method solved by the characterizing features of the main claim: advantageous Further developments of the method and preferred embodiments emerge from the dependent claims.

Die als Restmüll vorliegenden plattenförmigen Türfüllungen werden nach dem erfindungsgemäßen Verfahren zur Herstellung plattenförmiger Baumaterialien für Bauelemente verwendet. Hierzu wird in einem ersten Verfahrensschritt die plattenförmige Türfüllung geschreddert und so abgesiebt, dass die vom Sieb gegebene obere Grenze der Teilchengröße nicht über 20 mm liegt. Während das abgetrennte Oberkorn zurück in die Zerkleinerung geht, wird das abgesiebte körnige Material – ggf. nach Zwischenspeicherung – in einem zweiten Verfahrensschritt in einem Mischer mit PU-Material gemischt, wobei auf 10 kg körnigen Materials bis zu 2 kg PU-Material zugegeben wird. Diese so zubereitete Masse wird nach Zugabe von bis zu 1.5 kg Wasser in Formen gegossen und mit jeweils einem Stempel um mindestens 1/3-tel verdichtet. Nach dem Aushärten wird das plattenförmige Bauelement der mit einem Trennmittel beschichteten Form entnommen. Diese so hergestellten Bauelemente können wie Holz verarbeitet werden, und haben sehr günstige Dämmwerte in Bezug auf Wärme- und Schallübertragung.The as residual waste present plate-shaped door panels be according to the inventive method for the production of plate-shaped Building materials for Components used. This is done in a first step the plate-shaped door panel shredded and sieved so that the upper limit of particle size given by the sieve does not exceed 20 mm lies. While the severed upper grain back goes into the crushing, the sieved granular material - if necessary after Caching - in a second process step in a mixer with PU material mixed, taking on 10 kg of granular Material up to 2 kg of PU material is added. This prepared Mass is poured into molds after adding up to 1.5 kg of water and each compacted with a stamp at least 1/3 tel. After curing becomes the plate-shaped Component of coated with a release agent form removed. These components can be processed like wood, and have very cheap insulation values in terms of heat and sound transmission.

Als plattenförmige Bauelemente lassen sich diese ohne weiteres als Trockenstrich verlegen, was auch ein Verlegen auf Balkendecken ermöglicht. Die Rohdichte einer so hergestellten Estrichplatte liegt bei 600 kg/m3. Eine Estrichplatte bei einer Abmessung von 600 mm × 400 mm und einer Dicke von 50 mm hat eine Masse, die bei 7 kg liegt. Die Festigkeit einer solchen Estrichplatte liegt bei 4.000 kPa, wobei diese hohe Festigkeit für das Bauelement durch den Anteil an Glasfasern aus mit geschredderten GFK-Platten bestimmt ist. Diese Festigkeit erlaubt auch das Verlegen auf Balkendecken.As a plate-shaped components, these can easily be laid as a dry line, which also allows laying on beam ceilings. The bulk density of a screed plate thus produced is 600 kg / m 3 . A screed plate having a dimension of 600 mm × 400 mm and a thickness of 50 mm has a mass of 7 kg. The strength of such screed plate is 4,000 kPa, this high strength for the device is determined by the proportion of glass fibers from shredded GRP plates. This strength also allows laying on beam ceilings.

Neben den planen Bauelementen lassen sich mit dem so gewonnenen Baumaterial auch andere Formen von plattenförmigen Bauelementen herstellen. So können mit entsprechenden Formen mäanderförmige Strukturen hergestellt werden, die beispielsweise als Vorsatzschalen für Wände geeignet sind, wobei die Nuten zur Verstärkung der Dämmwirkung mit Dämmstoffen verfüllt werden können. Auch lassen sich in den Nuten Versorgungsleitungen verlegen.Next The plan components can be with the thus obtained building material also other forms of plate-shaped Produce components. So can with corresponding shapes meandering structures manufactured, which are suitable, for example, as facing shells for walls, wherein the grooves for reinforcement the insulation effect with insulation materials filled can be. Also can be laid in the grooves supply lines.

Ein Ausführungsbeispiel wird anhand der nachstehenden Figuren näher erläutert: dabei zeigen:One embodiment will be explained in more detail with reference to the following figures:

2: Estrichplatte aus dem Baumaterial (perspektivisches Schema): 2 : Screed panel from the building material (perspective scheme):

3: Mäanderförmig gestaltetes Bauelement aus dem Baumaterial (perspektivisches Schema). 3 : Meander-shaped component made from the building material (perspective scheme).

Die 1 zeigt das Verfahren zur Herstellung eines Bauelements schematisch, wie es beispielsweise als Formstein 12 (2) oder als mäanderförmige Vorsatzelemente (3) dargestellt ist. Dabei bedient sich das Verfahren eines Abfallwertstoffes 1 aus ein- oder beidseitig mit glasfaserverstärkten Kunststoffauflagen, insbesondere mit glasfaserverstärkten Polyesterplatten 2 beschichteten Dämmkernen 3 aus Polyurethan-Hartschaum besteht. Solche hierzu verarbeiteten Abschnitte fallen beispielsweise bei der Herstellung plattenförmiger Türfüllungen an, die im Wesentlichen aus einem aus Polyurethan-Hartschaum geschäumten PUR-Dammkern 3 besteht, der beidseits mit glasfaserverstärkten Polyester-Platten 2 beschichtet ist. Eine Beschichtung der GFK-Platten 2 mit einem Lack ist ohne weiteres tolerabel.The 1 shows the method for producing a device schematically, as for example as a molded block 12 ( 2 ) or as meander-shaped attachment elements ( 3 ) is shown. The process uses a waste material 1 from one or both sides with glass fiber reinforced plastic pads, especially with glass fiber reinforced polyester plates 2 coated insulating cores 3 made of rigid polyurethane foam. Such sections processed for this purpose, for example, in the production of plate-shaped door panels, which consist essentially of a foamed polyurethane rigid foam PUR dam core 3 consists, on both sides with glass fiber reinforced polyester plates 2 is coated. A Beschich tion of the GRP panels 2 with a paint is readily tolerable.

Wie 1 zeigt, wird zunächst in einem ersten Verfahrensschritt die plattenförmige Türfüllung 1 geschreddert, wie dies durch die zwei Walzen 4 angedeutet ist, so dass sich ein körniges mit GFK-Fasern durchsetztes Material ergibt, das einem Sieb 5 zugeht, auf den das Unterkorn in einen Bunker 6 abgesiebt wird, während das abgetrennte Oberkorn in einem Behälter gesammelt und zurückgeführt wird, um nach erneuter Zerkleinerung wieder dem Sieb 5 zuzugehen. Das durch das Sieb 5 gehende Unterkorn wird aus dem Bunker 6 zur weiteren Verarbeitung abgezogen, wobei es sich von selbst versteht, dass eine Zwischenspeicherung in einem Bunker 6.1, dem das zerkleinerte Material mit entsprechenden (nicht näher bezeichneten) Fördermitteln zugeführt wird, auch entfallen kann.As 1 shows, first, in a first process step, the plate-shaped door panel 1 shredded as this by the two rollers 4 is indicated, so that there is a granular interspersed with GRP fibers material that a sieve 5 goes down, on which the Unterkorn into a bunker 6 is screened while the separated upper grain is collected in a container and returned to again after comminution the screen 5 reach out. That through the sieve 5 Going undersize gets out of the bunker 6 deducted for further processing, it being understood that caching in a bunker 6.1 , to which the comminuted material is supplied with corresponding (unspecified) funding, may also be omitted.

Zur Herstellung der Bauelemente 12 bzw. 13 wird das körnige Material in einem Zwangsmischer 8 mit dem Bindemittel – in aller Regel ein aus einem Vorratsbehälter 8.1 entnommenes PUR-Material – gemischt, um als Baumaterial zur Herstellung der Bauelemente in Formen 10 abgefüllt zu werden. Unmittelbar vor dem Abfüllen der Formen 10 wird der mit dem Bindemittel durchsetzten Mischung eine das Aushärten bewirkende oder beschleunigende Komponente dosiert zugegeben – bei PUR-Material Wasser, wozu die Wasser-Zuleitung 9 mit einem Ventil 9.1 versehen ist. Zum Abfüllen wird der Zwangsmischer 8 – wie strichliert angedeutet – gekippt.For the production of the components 12 respectively. 13 The granular material is in a compulsory mixer 8th with the binder - usually one from a reservoir 8.1 taken PUR material - mixed to form as building material for the production of the components 10 to be bottled. Immediately before filling the molds 10 is added to the interspersed with the binder mixture added a curing causing or accelerating component - with PUR material water, including the water supply line 9 with a valve 9.1 is provided. For filling the compulsory mixer 8th - as indicated by dashed lines - tilted.

Die gefüllten Formen 10 werden mit einem Deckel 11 geschlossen, der als Stempel ausgebildet mit einem als hydraulischer Zylinder 11.1 dargestellten Pressmittel zusammenwirkt. Abgefüllt in der Form wird das Baumaterial mit dem Deckel 11 auf mindestens 60% für (relativ) weiche und auf höchstens 40% für (relativ) harte Platten zusammengedrückt. Während dieses Zusammendrückens reagiert die PUR-Masse mit dem Wasser unter Wärmenentwicklung und Aufschäumung, so dass sich die mit dem Deckel 11 geschlossene Form 10 voll ausfüllt.The filled forms 10 be with a lid 11 closed, designed as a stamp with a hydraulic cylinder 11.1 cooperates shown pressing means. Filled in the mold is the building material with the lid 11 compressed to at least 60% for (relatively) soft and at most 40% for (relatively) hard plates. During this compression, the PUR mass reacts with the water with evolution of heat and foaming, so that the with the lid 11 closed form 10 fully filled.

Entsprechend der Ausformung der Form 10 sowie des Deckels 11 wird diese abgegossene Masse entweder in einer Form als Estrichplatte 12 oder als Formstein, wie beispielsweise in den 2 und 3 dargestellt, der nach einer Aushärtezeit entformt und seiner Verwendung zugeführt wird. Dabei verleihen die schaumförmigen Bestandteile des PUR-Hartschaums dem Bauelement die hinreichende Isolier- und Wärmedämmfähigkeit. Die Estrichplatte 12 (2) ist im Wesentlichen eben, die in ihr enthaltenen, aus den GFK-Platten stammenden Fasern sind mit 12.1 angedeutet. Die mäanderförmig ausgebildete Vorsatzplatte 13 weist die geraden Flächenteile 13.2 und 13.3 verbindenden Schrägflächen 13.1 auf, wobei der Höhenversatz "h" der geraden Flächenteile 13.2 und 13.3 durch die Schrägflächen 13.1 gegeben ist.According to the shape of the mold 10 and the lid 11 This poured mass is either in a form of screed plate 12 or as a shaped brick, such as in the 2 and 3 represented, which is demolded after a curing time and fed to its use. The foam-like components of the rigid polyurethane foam give the component the sufficient insulating and thermal insulation capability. The screed plate 12 ( 2 ) is essentially flat, contained in it, derived from the GRP plates fibers are with 12.1 indicated. The meander-shaped attachment plate 13 points the straight surface parts 13.2 and 13.3 connecting inclined surfaces 13.1 on, wherein the height offset "h" of the even surface parts 13.2 and 13.3 through the inclined surfaces 13.1 given is.
