Abstract

The present invention relates to a process for producing foam plastic mouldings in which foamed, closed-cell plastic particles with a closed surface, preferably based on polystyrene, are brought into contact with a composition producing foamed, rigid or elastic epoxy foams, which fills the interstices between the plastic particles with foam, and foam mouldings produced in this manner, preferably in the form of sandwich elements with metallic outer layers.

Description

Beschreibung description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Schaumstoff-Formkörpers, bestehend im wesentlichen aus geschäumten, geschlossenzelligen Polystyroischaumstoffpartikelchen und einem geschäumten Bindemittel.The present invention relates to a method of making a Foam molded body, consisting essentially of foamed, closed-cell Polystyrene foam particles and a foamed binder.

Derartige Schaumstoff-Formkörper sind aus der eigenen DE-OS 31 20 121 bekannt.Such foam moldings are from our own DE-OS 31 20 121 known.

Aufgabe der Erfindung ist es, ein solches schäumbares Bindemittel zur Verfügung zu stellen, das mit den Polystyrolschaumstoffpartikelchen verträglich ist und das gleichzeitig eine eigene hervorragende Klebefähigkeit gegenüber Metallflächen aufweist, eine sehr gute wärmebeständige Klebebindung ergibt und eine gute Durchdringung der Polystyrolschaumstoffpartikelchen gewährleistet.The object of the invention is to provide such a foamable binder to make available that compatible with the polystyrene foam particles is and at the same time its own excellent adhesion to metal surfaces has a very good heat-resistant adhesive bond and a good penetration the polystyrene foam particles guaranteed.

Diese Aufgabe wird dadurch gelöst, daß man als Bindemittel ein Ausgangsproduktgemisch einsetzt, das zur Bildung von Expoxid-Schaumstoffen führt, vorzugsweise solchen mit einem Raumgewicht von 30 - 40 kg/m3.This object is achieved in that a starting product mixture is used as the binder used, which leads to the formation of epoxy foams, preferably those with a density of 30 - 40 kg / m3.

Derartige Epoxid-Schaumstoffsysteme sind dem Fachmann bekannt, beispielsweise aus Ullmann's Encyklopädie der technischen Chemie, Band 20, Seite 431 und den dort angegebenen Literaturstellen.Such epoxy foam systems are known to the person skilled in the art, for example from Ullmann's Encyclopedia of Industrial Chemistry, Volume 20, Page 431 and the there cited references.

Der erfindungsgemäße Einsatz der Expoxid-Schaumstoffsysteme ergibt ferner den großen Vorteil, daß gemäß der Erfindung vierte Auflage in relativ einfacher Weise Sandwichelemente mit dem vorstehend beschriebenen Kunststoffkern hergestellt werden können, deren Deckschichten aus Metallschichten bestehen.The inventive use of the epoxy foam systems results also the great advantage that according to the invention, fourth edition in relatively simple way sandwich elements with the plastic core described above can be produced whose cover layers consist of metal layers.

Die eingesetzten Polystyrolschaumstoffpartikelchen können entweder aus fertig geschäumten Polystyrolkügelchen bestehen oder durch Zerkleinern von Polystyrolschaumstoffen erhalten werden.The polystyrene foam particles used can either consist of pre-foamed polystyrene beads or by crushing polystyrene foams can be obtained.
