Description

Verfahren zur Formgebung von Kunstschaumstoffkörpern Die Erfindung bezieht sich auf ein Verfahren zur Formgebung von Kunstschaumstoffkörpern auf Polyurethan- oder Polyätherbasis. Kunstschaumstoffe sind bisher für verschiedene Verwendungszwecke bekanntgeworden, so unter anderem als Verbundmaterial für Unterlagsplatten in homogener Form für Polsterzwecke. Auch wurden aus homogenem Kunstschaumstoff beispielsweise Tierfiguren durch Schneiden hergestellt.Method for shaping synthetic foam bodies The invention relates to a process for shaping synthetic foam bodies on polyurethane or polyether base. Synthetic foams have so far been used for various purposes has become known, among other things as a composite material for production boards in homogeneous Form for upholstery purposes. They were also made of homogeneous synthetic foam, for example Animal figures made by cutting.

Die Erfindung bezweckt die Verwendung des Kunstschaumstoffes weiterzu ergänzen, beispielsweise Formkörper, Platten, Polsterbezüge, Teppiche und Wandbehänge herzustellen. The invention aims to further use the synthetic foam complement, for example moldings, panels, upholstery covers, carpets and wall hangings to manufacture.

Erreicht wird dieses gemäß der Erfindung dadurch, daß der Kunstschaumstoffkörper mit einem mehr oder weniger verdünnten Klebemittel durchtränkt und anschließend mittels Druckeinwirkung verformt wird. This is achieved according to the invention in that the synthetic foam body soaked with a more or less diluted adhesive and then is deformed by the action of pressure.

Ein weiteres Merkmal der Erfindung besteht darin, daß die Druckverformung unter Zwischenschaltung von Farbmitteln erfolgen kann. Auch ist es möglich, daß mehrere, mit einem Kleber getränkte homogene Schaumstoffolien oder Folienteile durch Druckeinwirkung miteinander verbunden und verformt werden. Another feature of the invention is that the compression deformation can be done with the interposition of colorants. It is also possible that several homogeneous foam sheets or sheet parts soaked with an adhesive Pressure are connected to each other and deformed.

Somit können auch bereits mit unterschiedlicher Dichte als Ausgangsprodukt dienende Schaumstofffolien nach dem erfindungsgemäßen Verfahren in einfachen Druckverfahren unter Druckverformung miteinander verbunden und gleichzeitig einer gewünschten Form angepaßt werden.This means that the starting product can also be used with different densities serving foam sheets according to the process according to the invention in simple printing processes connected to each other under compression deformation and at the same time of a desired shape be adjusted.

Es ist auch möglich, daß dem Kleber ein Farbmittel zugegeben wird. Hierbei kann es ebenfalls angebracht sein, daß einerseits dem Kleber ein Farbmittel zugegeben wird und andererseits die Druckstempel mit einem anderen Farbmittel versehen werden. Auch ist es möglich, daß die Kunstschaumstoffplatte bereits vor der Klebertränkung gefärbt wird. It is also possible that a colorant is added to the adhesive. Here it can also be appropriate that, on the one hand, the adhesive contains a colorant is added and on the other hand, the printing stamp is provided with a different colorant will. It is also possible that the synthetic foam sheet is already soaked in the adhesive is colored.

Das erfindungsgemäße Verfahren gestattet gleichfalls, daß die getränkten Kunstschaumstoffplatten und -folien zu Formkörpern durch Pressen oder Tiefziehen verarbeitet werden. Vorzugsweise wird das erfindungsgemäße Verfahren so angewendet, daß die Druckverformung nach dem Ablüften des Klebers und gegebenenfalls Härters und vor dem völligen Austrocknen und Einwirken der Komponenten Kleber und Härter aufeinander vorgenommen wird.The inventive method also allows that the soaked Foam sheets and foils to form molded bodies by pressing or deep drawing are processed. The method according to the invention is preferably applied in such a way that that the compression deformation after the adhesive and, if necessary, hardener has been flashed off and before the adhesive and hardener components dry out completely and take effect is made on each other.

Durch die unterschiedlichen Komponentenverhältnisse der Eintränkmenge, Schaumstoff-Plattenstärke, Preßgewichte, Preßformstrukturen und Einfärbungen beispielsweise durch gefärbte Klebelösungen oder Farb- und Prägdrücke können vielfach neue Roh-und Fertigungsprodukte mit bisher nicht vermuteten Eigenschaften und vielerlei neuen Einsatzm öglich- keiten hergestellt werden. Die nach dem erfindungsgemäßen Verfahren herstellbaren Materialien reichen von geformten hauchdünnen elastischen, seidenpapierartigen Gegenständen bis zu kernlederfesten und splittenharten Folien oder Formkörpern. Die Kleberlösung, für die beispielsweise eine solche auf Urethanbasis Verwendung finden kann, macht den Schaumkunststoff zusätzlich noch lichtunempfindlicher, reiß- und standfester, wobei die Luftdurchlässigkeit des Materials im wesentlichen in der alten Art erhalten bleiben kann. Due to the different component ratios of the impregnation amount, Foam sheet thickness, compression weights, compression molding structures and coloring, for example colored adhesive solutions or colored and embossed impressions can often create new raw and Manufactured products with previously unknown properties and many new ones Can be used can be produced. According to the method according to the invention Manufacturable materials range from molded wafer-thin elastic, tissue paper-like Objects up to core leather-proof and split-hard foils or moldings. The adhesive solution, for which, for example, a urethane-based one is used can find, makes the foam plastic even less sensitive to light, tear- and more stable, the air permeability of the material being substantially in the old way can be preserved.

Weiterhin können auch selbstklebende Dichtungsstreifen oder Gehäuse und Verpackungen durch Kaltverpressen hergestellt werden. Ein weiterer Vorteil der mit Kleber getränkten Folien aus Kunstschaumstoff besteht darin, daß die Atmungsfähigkeit erhalten bleibt. Die Dehnfähigkeit des Kunstschaumstoffes ermöglicht die Prägung von Hohlformen und das faltenfreie Kaschieren um Formkörper aus z. B. Self-adhesive sealing strips or housings can also be used and packaging is produced by cold pressing. Another benefit of the Foam foils impregnated with adhesive consists in the fact that breathability preserved. The elasticity of the synthetic foam enables the embossing of hollow molds and wrinkle-free lamination to moldings made of z. B.
