Abstract

Metal foil and thermoplastic scrap are comminuted to give chips. The chips are introduced into an extruder for the melting of thermoplastics and are prepared for extrusion therein. The mixture of the molten plastic and the metal foil chips is continuously moulded to give the moulding with the aid of an extrusion die connected to the extruder.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Formkörpern aus Metall und einem thermoplastischen Kunst­ stoff.The invention relates to a method of manufacture of moldings made of metal and a thermoplastic art material.

Zahlreiche Artikel des täglichen Lebens bestehen aus Metall, andere bestehen aus thermoplastischem Kunststoff. Weitere Artikel bestehen aus thermoplastischem Kunststoff, der zu­ mindest einseitig und bereichsweise mit einer Metallfolie beschichtet oder in Verbund gebracht ist. Das gilt insbes. für Artikel der Verpackungsindustrie, die z. B. aus einem Kunststoffbehälterteil und einer Abdeckung aus Metallfolie bestehen. Bei der Herstellung dieser Artikel und nach deren Gebrauch entstehen Abfälle, die bisher, insbes. in bezug auf die Kunststoffkomponente, die Umwelt und Deponien belasten. Zwar ist es bekannt, bei der Herstellung von Kunststoffolien entstehende Besäumabfälle in eine Kunststoffschneckenpresse, einen sog. Extruder, zurückzuführen, um daraus erneut Kunst­ stoffolien herzustellen. Eine solche Rückführung ist jedoch bisher nicht durchgeführt worden, wo es sich um Kombinationen von thermoplastischem Kunststoff und Metallfolie handelt. Im übrigen fehlt ein einfaches Verfahren, welches es erlaubt, aus Metall und thermoplastischem Kunststoff, vorzugsweise aus entsprechenden Abfällen, Gegenstände eigener Art herzu­ stellen, die hohen Anforderungen in bezug auf Festigkeit, Stabilität und Korrosionsverhalten genügen.Many everyday items are made of metal, others are made of thermoplastic. Further Articles are made of thermoplastic plastic, which too at least on one side and in some areas with a metal foil is coated or combined. This applies in particular. for articles in the packaging industry, e.g. B. from one Plastic container part and a cover made of metal foil consist. In the manufacture of these articles and after Use waste that has so far, especially in relation to the plastic component, the environment and landfills. It is well known in the manufacture of plastic films trimmings generated in a plastic screw press, a so-called extruder, to make art out of it again to produce fabric films. However, such a return is So far it has not been carried out where there are combinations is about thermoplastic and metal foil. There is also no simple procedure that allows made of metal and thermoplastic, preferably from corresponding waste, objects of their own kind make high demands in terms of strength, Stability and corrosion behavior are sufficient.

Der Erfindung liegt die Aufgabe zugrunde, aus Metall und ther­ moplastischem Kunststoff Gegenstände eigener Art herzustellen, die z. B. in der Bauindustrie, in der Verpackungsindustrie, aber für andere Zwecke eingesetzt werden können. The invention has for its object from metal and ther to produce plastic materials of their own kind, the z. B. in the construction industry, in the packaging industry, but can be used for other purposes.  

Zur Lösung dieser Aufgabe ist Gegenstand der Erfindung ein Verfahren zur Herstellung von Formkörpern aus Metall und ei­ nem thermoplastischen Kunststoff, welches dadurch gekennzeich­ net ist, daß Abfälle von Metallfolie und von thermoplasti­ schem Kunststoff zu Schnitzeln zerkleinert werden, daß die Schnitzel in eine Schneckenstrangpresse für das Aufschmelzen von thermoplastischem Kunststoff eingeführt und darin extru­ dierfähig aufbereitet werden und daß die Mischung aus dem aufgeschmolzenen Kunststoff und den Schnitzeln aus Metallfo­ lie mit Hilfe eines an die Schneckenstrangpresse angeschlos­ senen Strangpreßwerkzeuges kontinuierlich zu dem Formkörper geformt wird, der danach in Abschnitte abgelängt werden kann.The object of the invention is to achieve this object Process for the production of moldings from metal and egg nem thermoplastic, which is characterized by net is that waste of metal foil and thermoplastic chemical plastic shredded into chips that the Schnitzel in a screw extruder for melting of thermoplastic introduced and extru therein be prepared and that the mixture of the melted plastic and the chips from metal fo lie connected to the screw extruder with the help of a his extrusion tool continuously to the shaped body is formed, which can then be cut into sections.

In dieser Lehre zum technischen Handeln liegt eine Abstim­ mungsregel, und zwar dahingehend, das Mischungsverhältnis Metallfolie/Kunststoff so einzurichten, daß eine extrudier­ fähige Aufbereitung in einem Extruder möglich ist. Der Anteil an thermoplastischem Kunststoff darf nicht zu niedrig sein, kann aber andererseits praktisch beliebig hoch sein. Die Schnitzel sollen eine Kantenlänge von einigen mm, z. B. von 2 mm, aufweisen.There is a vote in this teaching on technical action rule, namely the mixing ratio Set up metal foil / plastic so that an extruded capable preparation in an extruder is possible. The amount thermoplastic must not be too low, on the other hand, it can be practically arbitrarily high. The Schnitzel should have an edge length of a few mm, e.g. B. from 2 mm.

Eine bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß Abfälle, insbes. Besäumabfälle, von zu­ mindest einseitig und bereichsweise mit Metallfolie beschich­ teten Verpackungsbehältern und/oder Verpackungsmaterialien als Ausgangsmaterial eingesetzt werden. Insoweit nutzt die Erfindung die Tatsache, daß bei den Abfällen dieser Art die Verhältnisse so liegen, daß ohne weiteres eine extrudierfä­ hige Aufbereitung in einem Extruder möglich ist. Das ist über­ raschend. Hinzukommt, daß die Metallfoliebestandteile und die Kunststoffbestandteile bereits innig miteinander verei­ nigt sind. Das alles gilt insbes. dann, wenn mit Abfällen gearbeitet wird, die zu 80 bis 90 Gew.% aus Kunststoff, zu 10 bis 20 Gew.% aus Metallfolieschnitzel bestehen. Zu in qua­ litativer Hinsicht besonders guten Formkörpern gelangt man, wenn der Kunststoff aus Polyvinylchlorid besteht und die Me­ tallfolie aus einer Aluminiumlegierung. Im Rahmen der Erfin­ dung liegt es, den Schnitzeln zusätzlich Metallfolieschnitzel beizumischen. Im Rahmen der Erfindung liegt es fernerhin, den Schnitzeln zusätzlich feinteilige thermoplastische Kunst­ stoffe, beispielsweise Kunststoffolienschnitzel, beizumischen. Es versteht sich, daß man den Schnitzeln auch andere Füller beimischen kann. - Im Rahmen der Erfindung kann mit allen üblichen Schneckenstrangpressen gearbeitet werden. Vorzugs­ weise arbeitet man mit Doppelschneckenextrudern.A preferred embodiment of the invention is thereby characterized that waste, in particular trimming waste, from to Coat metal foil on at least one side and in some areas teten packaging containers and / or packaging materials be used as starting material. To that extent uses the Invention the fact that the waste of this type Ratios are such that an extrudable processing in an extruder is possible. That is about surprising. In addition, the metal foil components and the plastic components are already intimately united  are nigt. All of this applies in particular when it comes to waste is worked, which is 80 to 90 wt.% Plastic, too 10 to 20% by weight consist of metal foil chips. Too in literally, particularly good moldings are obtained, if the plastic is made of polyvinyl chloride and the Me tall foil made of an aluminum alloy. As part of the Erfin It is appropriate to add a scrap of metal foil to the chips to mix. It is also within the scope of the invention the chips also fine-particle thermoplastic art Add substances such as shredded plastic wrap. It goes without saying that the fillets are also other fillers can mix. - Within the scope of the invention can with all usual screw extruders to be worked. Preferential wise one works with twin screw extruders.

Arbeitet man nach der Lehre der Erfindung, so kommt man zu Formkörpern, die sich in mechanischer Hinsicht besonders aus­ zeichnen. Der Metallbestandteil bildet in den Formkörpern eine Bewehrung und ein Skelett in einer Kunststoffmatrix, was den Formkörpern besondere Biegefestigkeit und Druckfestig­ keit, aber auch besondere Dauerfestigkeit, verleiht. Der Kunststoffbestandteil macht die Formteile darüber hinaus witterungsbeständig und in den meisten Umgebungen auch außer­ ordentlich korrosionsfest. Die hergestellten Formkörper kön­ nen daher für viele Verwendungszwecke in der Bauindustrie und in der Verpackungsindustrie, z. B. in Form von Wandplat­ ten oder Deckplatten für Wandplatten, Fußbodenplatten und Deckenplatten oder Deckplatten für Fußboden- und Deckenplat­ ten, Profilen, auch für die Herstellung von Transportpaletten, eingesetzt werden. Insbes. lassen sich beliebige Profile durch Strangpressen formen, z. B. auch Kantenschutzprofile, wie sie in der Verpackungsindustrie gebräuchlich sind.If one works according to the teaching of the invention, one comes to Shaped bodies that are particularly mechanical to draw. The metal component forms in the moldings a reinforcement and a skeleton in a plastic matrix, which gives the moldings particular flexural strength and compressive strength ability, but also special fatigue strength. The Plastic component also makes the molded parts weather-resistant and in most environments also outside neatly corrosion-resistant. The moldings produced can Therefore, for many uses in the construction industry and in the packaging industry, e.g. B. in the form of wall plate or cover plates for wall plates, floor plates and Ceiling plates or cover plates for floor and ceiling plate profiles, also for the production of transport pallets, be used. Esp. can be any profiles Form extrusion, e.g. B. also edge protection profiles, such as they are used in the packaging industry.
