Abstract

The method is for treatment of metal-plastic cpd. materials, e.g., aluminium-plastic cpd. sheeting. Deformation of the cpd. material and sepn. occurs by using the difference between the individual materials. The cpd. material is subjected to selective grinding, and prior to this process is broken into very small pieces with a dia. of less than 10mm.The grinding takes place in a micro vortex mill in the ultrasound range. The cpd. material is deformed by heating and/or cooling, e.g., in an extruder, and it is the metal constituents which are partic. deformed. Sepn. takes place by sieving or by flotation in a flowing bed. After dyring the metal and/or plastic constituents are made into briquets.

Description

Die Erfindung betrifft ein Verfahren zum Behandeln von Metall-Kunststoff-Verbundstoffen, beispielsweise von Alumi­ nium-Kunststoff-Verbundfolie.The invention relates to a method for treating Metal-plastic composites, for example from Alumi nium plastic composite film.

Verbundstoffe kommen heute in fast allen Bereichen des täglichen Lebens vor. Gedacht ist vor allem an den Ver­ packungsbereich, aus dem Metall-Kunststoff-Verbundfolien überhaupt nicht mehr wegzudenken sind.Composites come in almost all areas of the world today daily life. Above all, the Ver packing area, made of metal-plastic composite films are indispensable at all.

Probleme bilden diese Verbundfolien vor allem bei der Ent­ sorgung, da bislang ein Trennen der Metallbestandteile vom Kunststoffbestandteil nicht stattfindet. Diese Verbund­ stoffe werden heute fast ausschließlich verbrannt oder deponiert. Daß dies nicht umweltverträglich ist, bedarf keiner näheren Erläuterung.These composite films are particularly problematic when it comes to Ent supply, as there has been a separation of the metal components from the Plastic component does not take place. This composite fabrics are almost exclusively burned or deposited. It is necessary that this is not environmentally compatible no further explanation.

Zu den Metall-Kunststoff-Verbundstoffen, welche zu­ künftig geordnet entsorgt werden müssen, gehören vor allem auch die Abfälle aus der Leiterplattenfabrikation. Gerade dort sind mit Metall beschichtete Kunststoffplatten bis­ lang unersetzlich.To the metal-plastic composites, which too Above all, it must be disposed of properly in the future also the waste from printed circuit board production. Just  there are plastic plates coated with metal up to long irreplaceable.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren der o.g. Art zu entwickeln, mit welchem Verbund­ stoffe so behandelt werden können, daß eine ordnungsgemäße Entsorgung oder aber eine Rückgewinnung von Wert­ stoffen erfolgt.The present invention is based on the object Procedure of the above Way to develop with which association fabrics can be treated so that a proper Disposal or a recovery of value fabrics.

Zur Lösung dieser Aufgabe führt eine Deformierung des Verbundstoffes und eine Trennung unter Ausnutzung eines Unterschiedes der einzelnen Stoffe.Deformation of the Composite and a separation using one Difference between the individual substances.

Dabei kann die Deformierung des Verbundstoffes durch eine selektive Mahlung erfolgen.The deformation of the composite material by a selective grinding.

Durch die selektive Mahlung erfolgt ein Zerkleinern des Verbundstoffes in kleinste Komponente, wobei sich die einzelnen Komponenten bezüglich Dimension und Geometrie infolge ihrer unterschiedlichen Festigkeitseigenschaften auch unterschiedlich verhalten. Es hat sich herausge­ stellt, daß beim Mahlen beispielsweise in einer Mikro­ wirbelmühle die Bestandteile aus Polyäthylen im wesentli­ chen unverändert bleiben, während Bestandteile beispiels­ weise aus Aluminium, die vorher in flächiger Form vorla­ gen, zu mikroskopisch kleinen Kügelchen deformiert werden. Bestandteile aus Polystyrol beispielsweise werden ebenfalls deformiert, jedoch nur bis zu einer Größe, welche erheblich größer ist als die bis zu mikroskopisch kleinen Aluminiumkügelchen.The selective grinding results in a crushing of the Composite in the smallest component, the individual components with regard to dimension and geometry due to their different strength properties also behave differently. It turned out represents that when grinding, for example in a micro vortex mill the components made of polyethylene essentially Chen remain unchanged, while components for example made of aluminum, which was previously available in flat form be deformed into microscopic spheres. Polystyrene components, for example, are also made deformed, but only up to a size which is considerably larger than that up to microscopic Aluminum beads.

Eine Deformierung kann allerdings auch durch eine Beaufschlagung des Verbundstoffes mit Kälte oder Wärme erfolgen. Dabei werden die Bestandteile des Verbundstoffes selbstverständlich unterschiedlich deformiert, vor allem, wenn es sich bei den unterschiedlichen Bestandteilen um ein Metall bzw. um ein Kunststoff handelt. In jedem Fall findet hier aber bereits schon ein partielles Abtrennen der Verbundstoffe voneinander statt, so daß der spätere Trennvorgang wesentlich erleichtert wird. Die thermische Behandlung des Verbundstoffes kann beispielsweise in einem Extruder erfolgen.A deformation can also be caused by a Applying cold or heat to the composite respectively. The components of the composite of course deformed differently, above all, if the different components are one Metal or a plastic. In any case  here already a partial separation of the Composites from each other instead, so that the later Separation process is much easier. The thermal Treatment of the composite can, for example, in one Extruder done.

Das unterschiedliche Deformieren bewirkt, daß sich die einzelnen Bestandteile voneinander trennen, so daß dann später ein Scheiden von Kunststoff und Metallteilen auf einfache Art und Weise möglich ist. Beispielsweise werden die Metallteile durch Sieben von dem Kunststoff getrennt, da der Kunststoff im Sieb verbleibt, während die mikroskopisch kleinen Aluminiumkügelchen durch die Maschen fallen. Ein Trennen ist auch möglich in einem Fließbett oder durch Flotation, wobei die mikroskopisch kleinen Metallkügelchen absinken, während der Kunststoff zur Oberfläche der Trennflüssigkeit treibt.The different deforming causes the separate individual components from each other so that later a separation of plastic and metal parts simple way is possible. For example the metal parts are separated from the plastic by sieving, because the plastic remains in the sieve while the microscopic aluminum balls through the mesh fall. Separation is also possible in a fluid bed or by flotation, the microscopic Metal balls sink while the plastic is used Surface of the separation liquid drives.

Sobald dann durch das Trennen eine Metall- und/oder Kunststoffraktion gewonnen ist, sollte diese bevorzugt getrocknet und zur Verminderung des beanspruchten Raumes brikettiert werden.As soon as then by separating a metal and / or Plastic fraction is won, this should be preferred dried and to reduce the space occupied be briquetted.

Es versteht sich von selbst, daß bei einem Deformieren durch selektives Mahlen vor dem eigentlichen Mahlprozeß der Verbundstoff einer Vorzerkleinerung unterworfen werden sollte, damit nicht diese ganze Arbeit innerhalb der Mühle durchgeführt werden muß. Dabei erfolgt ein Zerkleinern des Verbundstoffes auf Teile mit einem Durchmesser von weniger als 10 mm.It goes without saying that when deforming by selective grinding before the actual grinding process Composite is subjected to a pre-shredding shouldn't do all this work inside the mill must be carried out. The shredding of the Composite on parts with a diameter of less than 10 mm.

Als Vorrichtung hat sich besonders eine Mikrowirbelmühle angeboten, welche mit einem Rotor bestückt ist, der so hoch beschleunigt werden kann, daß die Behandlung im Ultraschallbereich erfolgt. Hierdurch werden in der Mikromühle Kleinstwirbel erzeugt, in denen die einzelnen Bestandteile gegeneinander prallen, wodurch schlußend­ lich der metallische Teil seine mikroskopisch kleine Kugelform erreicht und damit von dem Kunststoffbestand­ teil getrennt wird.A microfluidic mill has proven to be a particularly useful device offered, which is equipped with a rotor that is so high can be accelerated that the treatment in Ultrasound range is done. As a result, in the Micro mill generates small vortices in which the individual Components collide against each other, which makes them conclusive  Lich the metallic part its microscopic Spherical shape achieved and thus from the plastic inventory part is separated.

Insgesamt arbeitet dieses Verfahren außerordentlich wir­ kungsvoll und kostengünstig. Zu erwähnen ist vor allem, daß das Metall nunmehr in fast reiner Form vorliegt und so äußerst günstig wiederverwertet werden kann.Overall, this process works extremely well creative and inexpensive. It is important to mention that the metal is now in almost pure form and so can be recycled extremely cheaply.
