Description
Es ist bekannt, sogenannte Preßplatten aus Schaumstoffabfällen unter Anwendung erhöhter Drücke und Temperaturen herzustellen. Die Notwendigkeit druckfester Formen setzt hierfür jedoch einen vergleichsweise hohen apparativen Aufwand voraus; und da auch die Haftung der Schaumstoffteile untereinander allein von einer zweckentsprechenden Abstimmung des Preßdruckes auf die Temperatur abhängt, ist die Genauigkeit der verwendeten Regeleinrichtungen für die Durchführbarkeit des bekannten Verfahrens von wesentlicher Bedeutung. Nach einem anderen: bekanntgewordenen Vorschlag sollen Kunstharze von schaumartiger Struktur in zerkleiner tem Zustand zwischen Walzen oder in Knetmaschinen zusammen mit einem geeigneten Bindemittel als einheitliche Mischung verarbeitet und anschließend zu Platten zusgezogen oder in Formen gepreßt werden. Für die Verwertüng' von Schaumstoffflocken ohne weitere Nachbehandlung kann hieraus ebensowenig eine Anregung entnommen werden wie aus einem weiteren bekannten Vorschlag, Kunstschaumstoffkörper mit Umhüllungen aus festen, wasserdichten Stoffen zu versehen. It is known to take so-called press plates from foam waste Use increased pressures and temperatures to produce. The need for more pressure resistant For this, however, forms requires a comparatively high outlay in terms of equipment; and since the adhesion of the foam parts to one another depends solely on an appropriate one Adjustment of the pressing pressure depends on the temperature, the accuracy is the one used Control devices are essential for the feasibility of the known method Meaning. According to another proposal that has become known, synthetic resins from Foam-like structure in a crushed state between rollers or in kneading machines processed together with a suitable binding agent as a uniform mixture and then drawn into sheets or pressed into molds. For the recovery Foam flakes without further post-treatment cannot be used either Suggestions are taken as from another known proposal, synthetic foam body to be provided with covers made of solid, waterproof materials.
Der Erfindung liegt als besondere Aufgabe die vorteilhafte Verwertung der in der Schaumstofffabrikation in Form von Schnittresten, Flocken oder Schnitzeln anfallenden Abfälle unter Vermeidung größeren maschinellen Aufwandes zugrunde. Diese Aufgabenstellung schließt den Einsatz druckfester Formen und auch die Anwendung höherer Drücke und Temperaturen von vornherein aus und legt der Suche nach geeigneten @ Lösungsformen erhebliche Beschränkungen auf. A particular object of the invention is the advantageous utilization that in foam production in the form of leftovers, flakes or chips generated waste while avoiding major mechanical effort. These The task includes the use of pressure-resistant forms and also the application higher pressures and temperatures from the outset and starts looking for suitable ones @ Forms of solution have considerable limitations.
-t?ns Verfaltrer@ zum Herstellen von Schichtsoffen unter Verwendung von Schaumstoffschnitzeln und einer oder mehreren flächenhaften Trägerschichten aus biegsamen Werkstoffen ist dadurch gekennzeichnet, daß die Trägerschichten mit einem Haftmittelaufstrich versehen und anschließend mit Schaumstoffschnitzeln beflockt werden, wobei gegebenenfalls zusätzlich die Schaumstoffschnitzel nach dem Aufflocken auf die Trägerschichten mit einen Haftmittel besprüht werden können.-t? ns Verfaltrer @ for making laminates using of foam chips and one or more flat carrier layers made of flexible materials is characterized in that the carrier layers with provided with an adhesive spread and then flocked with foam chips are, if necessary, additionally the foam chips after the flaking can be sprayed onto the carrier layers with an adhesive.
Die Erfindung nutzt die zunehmende Verwendung von Schaumstoffen, insbesondere geschäumten Polyurethanen und ähnlichen Kunststoffen, als Polster-und Verpackungsmaterial und eröffnet einen Weg zur gewinnbringenden Verwertung der unvermeidlichen Abfälle. Die das Rohmaterial für das erfindungsgemäße Verfahren bildenden Abfallstucke können in unbegrenzten Mengen auf wirtschaftliche Weise zu Teilstücken beliebiger Größenordnung zerschnitzelt werden, wobei sich die Dicke der fertigen Schichtstoffe je nach der Auswahl der Schnitzelgröße in weiten Grenzen variieren läßt. Die haftende Anordnung der Schaumstoffflocken zwischen äußeren zugfesten Trägerschichten führt zu relativ formsteifen plattenförmigen Gebilden, die bei niedrigem Eigengewicht ein günstiges statisches Festigkeitsverhalten aufweisen und in dieser Hinsicht etwa der bekannten Wellpappe vergleichbar sind. The invention takes advantage of the increasing use of foams, in particular foamed polyurethanes and similar plastics, as upholstery and Packaging material and opens a way to profitable recovery of the inevitable Waste. The scrap pieces forming the raw material for the method according to the invention can be used in unlimited quantities in an economical way to cut any part Shredded order of magnitude be, with the thickness of the finished laminates can vary within wide limits depending on the selection of the schnitzel size. The adherent Arrangement of the foam flakes between outer tensile carrier layers leads to relatively dimensionally stable plate-shaped structures that are low in weight have a favorable static strength behavior and in this regard for example are comparable to the well-known corrugated cardboard.
Sie sind in weiten Bereichen der Technik zur Schall- und Wärmeisolierung, aber auch als Verpackungsmaterial, für Polsterzwecke oder zum Dämpfen von Schwingungen verwendbar. Da das Verfahren ohne größere maschinelle Einrichtungen mit üblichen Werkstattmitteln durchführbar ist, lassen sich die Herstellungskosten sehr niedrig halten. They are used in many areas of technology for sound and heat insulation, but also as packaging material, for upholstery purposes or to dampen vibrations usable. Since the process does not require any major mechanical equipment with usual Workshop means is feasible, the manufacturing costs can be very low keep.
Das Material für die Trägerschichten wird je nach dem vorliegenden Verwendungszweck des Schichtkörpers gewählt. Geeignete Werkstoffe sind beispielsweise für Polsterzwecke Gewebe, Filz oder Vlies aus natürlichen oder künstlichen Fasern oder auch Kunststoffolien, für Verpackungszwecke Pappe, Wellpappe oder Papier, für Täidhnerwaren und Schuhbedarfs artikel Leder oder Kunstleder und für Isolierzwecke Kunststoff- oder Metallfolien und Bleche. The material for the carrier layers will depend on the present Purpose of use of the laminate selected. Suitable materials are, for example for upholstery purposes fabric, felt or fleece made from natural or artificial fibers or even plastic films, for packaging purposes cardboard, corrugated cardboard or paper, for Horse and footwear articles made of leather or imitation leather and for insulation purposes Plastic or metal foils and sheets.
Zur Verbesserung der Klebefreudigkeit kann das Material der Trägerschichten gegebenenfalls vor dem Aufbringen des Haftmittels noch'auf geeignete Weise vorbehandelt werden.., Es lassen sich Schichtkörper mit beliebig vielen Lagen Schnitzeln und Trägerfolie in abwecMelnder Aufeinanderfolge herstellen. Gegebenenfalls können die Schichtkörper auch aus nur einer einzigen Trägerfolie mit aufgeflockten Schaumstoffscnitzeln bestehen. Für praktische Einsatzzwecke besteht außerdem die Möglichkeit, die erfindungsgemäßen Schichtkörper in mehreren Lagen übereinander zu verwenden. To improve the ability to bond, the material of the carrier layers optionally pretreated in a suitable manner before applying the adhesive be .., It can be laminated with any number of layers of Schnitzeln and Produce carrier film in alternating succession. If necessary, the Laminated body also made from just a single carrier film with flaked foam chips exist. For practical purposes there is also the possibility of using the invention To use laminated bodies in several layers on top of each other.
