Abstract
Description
Die mit dem Verfahren herzustellenden Teile sind dauerhaft und formstabil. Sie können bei Möbeln und anderen industriellen Produkten sowie in Architektur und Innenausbau zum Einsatz kommen. Es können sowohl zwei- und dreidimensional geformte Teile als auch flache Platten hergestellt werden, in Materialstärken von ca. 1 mm bis mindestens 20 mm. Diese können als struktureller Teil einer Konstruktion, wegen ihrer ansprechenden optischen oder haptischen Eigenschaften oder wegen ihrer akustischen Wirksamkeit eingesetzt werden.The Parts to be produced by the process are durable and dimensionally stable. They can be used in furniture and other industrial Products as well as in architecture and interior design. It can be both two- and three-dimensionally shaped parts as flat plates are produced, in material thicknesses from about 1 mm to at least 20 mm. These can be considered structural Part of a construction, because of its appealing optical or haptic properties or because of their acoustic effectiveness be used.
Des weiteren beschreibt die Erfindung die Möglichkeit und das Verfahren zwei oder mehrere so hergestellter Formteile untereinander zu komplexeren Formkörpern zu verbinden.Of Furthermore, the invention describes the possibility and the Method two or more moldings thus produced with each other to connect to more complex moldings.
Die hier vorgelegte Erfindung stellt in allgemeiner Form ein Verfahren zur Herstellung von Formteilen aus einem in Schichten aufgebauten Papier-Kunststoff-Verbunds dar. Im Speziellen wird bei diesem Verfahren ein beidseitig mit einem thermoplastischen Kunststoff beschichtetes Papier- oder Kartonmaterial verwendet, wodurch die Herstellung in großem Maße vereinfacht und beschleunigt wird. Die Erfindung baut auf der bekannten industriellen Produktion von Papier auf, bei der es möglich ist, in einem integrierten Herstellungsschritt ein- oder beidseitig eine thermoplastische Kunststoffschicht auf die Papier- bzw. Kartonbahn aufzubringen Solche beschichteten Papiere werden durch die Papierindustrie bereits in unterschiedlichen Stärken und mit unterschiedlichen Beschichtungen hergestellt. Bewährt hat sich die Herstellung und Verwendung solcher beschichteter Kartonarten in großen Mengen für Nahrungsmittelverpackungen.The The present invention provides a method in general form for the production of molded parts from a layered Paper-plastic composite dar. In particular, in this process a coated on both sides with a thermoplastic material Paper or cardboard material used, thereby reducing the production in greatly simplified and accelerated. The Invention builds on the well-known industrial production of paper on which it is possible in an integrated manufacturing step on one or both sides of a thermoplastic layer of plastic apply the paper or board web Such coated papers are already being developed by the paper industry in different strengths and made with different coatings. Has proven the manufacture and use of such coated board types in large quantities for food packaging.
Im folgenden sollen die Begriffe Lagen und Schichten wie folgt verwendet werden: Lagen bezeichnen die im Herstellungsprozess zur Verwendung kommenden einzelnen Stücke oder Bögen flachen Ausgangsmaterials, im Regelfall eben kunststoffbeschichteter Karton, die lose zusammengefasst und dann verpresst werden. Schichten bezeichnen die im Prozess oder im Endprodukt vorhandenen übereinander liegenden Schichten aus unterschiedlichem Material, im Regelfall sind das Karton bzw. Papier und die Beschichtungen aus thermoplastischem Kunststoff.in the Following are the terms layers and layers used as follows Layers refer to those in the manufacturing process for use shallow individual pieces or bows Starting material, usually just plastic-coated cardboard, which are loosely collected and then pressed. Layers denote the in the process or in the final product on top of each other lying layers of different material, as a rule are the cardboard or paper and the coatings of thermoplastic.
Das erfindungsgemäße Verfahren stellt sich wie folgt dar: mehrere Lagen eines solchen beidseitig mit einem thermoplastischen Kunststoff beschichteten Kartons werden in einer zwei- oder mehrteiligen Form bei einer Temperatur nahe dem Schmelzpunkt des Kunststoffs und einem Druck von ca. 1–10 MPa gepresst. Um ein Ankleben an das Werkzeug zu vermeiden wird für die Oberflächen eine Trennschicht aus Silikonpapier verwendet. Die Haltezeit beträgt im Regelfall ca. 2 Minuten. Dabei verschmelzen die einander zugeordneten Kunststoffschichten benachbarter Lagen zu einer Schicht, so dass ein formstabiles Produkt einer bestimmten Materialstärke mit mehrschichtigem Aufbau entsteht. Nach dem Entformen kühlt das Teil ab und erreicht dabei seine endgültige Härte.The inventive method is as follows dar: several layers of such on both sides with a thermoplastic Plastic coated cartons are in a two- or multi-part form at a temperature near the melting point of the plastic and a Pressure of about 1-10 MPa pressed. To stick to the Tool is to be avoided for the surfaces used a release layer of silicone paper. The holding time is usually about 2 minutes. The mutually associated merge Plastic layers of adjacent layers to form a layer, so that a dimensionally stable product of a certain material thickness arises with multi-layered structure. Cool after demolding the part off and thereby reaches its final hardness.
Wegen des mehrschichtigen Aufbaus, des Pressvorgangs und des vorgeschlagenen Einsatzgebietes ist es sinnvoll, das Verfahren und das Endprodukt mit der Herstellung von Formsperrholz zu vergleichen. Bei formgepresstem Sperrholz gibt es nach dem Stand der Technik verschiedene technische Verfahren, denen jeweils gemeinsam ist, dass mehrere Lagen Holzfurnier unter Hitze und Druck mittels eines bei hohen Temperaturen von ca. 150°C bis 200°C aushärtenden Klebstoffs, in der Regel ein Polyurethanharz, zu formstabilen, dauerhaften Teilen gepresst werden. Die Haltezeiten variieren je nach der Methode durch welche während dem Pressvorgang die notwendigen Temperatur im Material erzeugt wird. Bei dauerhaft beheizten Pressen liegt die Haltezeit üblicherweise bei ca. 10 min. Beim Aushärten des Klebstoffs durch Mikrowellenstrahlung kann die Haltezeit deutlich kürzer ausfallen, z. B. ca. 2 min, jedoch erlaubt diese Technik keine Endstärken unter 10 mm. Des weiteren gibt es die Möglichkeit, Pressformen elektrisch jeweils für die Dauer der Haltezeit zu erwärmen. Die Verfahren zur Herstellung von formgepresstem Sperrholz dürfen als weitgehend ausgereift gelten. In allen Fällen stellt jedoch die Bereitstellung der Furniere in großer Menge und guter, gleichbleibender Qualität eine Schwierigkeit dar. Weiterhin sind bei der Verarbeitung der Furniere zu Formsperrholz immer noch mehrere Arbeitsschritte nur von Hand auszuführen, z. B. die Sortierung der Furnierlagen und das Einbringen der Klebstofflagen oder das Aufbringen des Klebstoffs in flüssiger Form auf die Furnierlagen. Der Bezug auf die Herstellung von Formsperrholz spielt hier deswegen eine Rolle, da mit dem hier vorgelegten Verfahren in Aufbau und Form ähnliche Formteile hergestellt werden können und da die Herstellung ohne Veränderung der Technik, mit angepassten Einstellungen, auf gleichen Werkzeugen erfolgen kann wie bei Formsperrholz, wodurch die Presswerkzeuge in einschlägig bekannter Weise vorbereitet und hergestellt werden können.Because of of the multilayer structure, the pressing process and the proposed Field of application, it makes sense, the process and the final product to compare with the production of molded plywood. In case of compression molded There are plywood according to the prior art, various technical Procedure, which is common in each case that several layers of wood veneer under heat and pressure by means of a high temperature of approx. 150 ° C to 200 ° C curing adhesive, usually a polyurethane resin, to form-stable, durable parts be pressed. The holding times vary depending on the method which during the pressing process, the necessary temperature generated in the material. For permanently heated presses the holding time usually at about 10 min. When curing the Adhesive by microwave radiation, the retention time significantly shorter, z. B. about 2 minutes, but this allows Technology no end thicknesses below 10 mm. Furthermore there it's possible to use compression molds electrically for each to heat the duration of the hold time. The procedures for Manufacture of molded plywood may be considered to be largely mature be valid. In all cases, however, provides the deployment the veneers in large quantity and good, consistent Quality is a difficulty dar. Furthermore, in the Processing the veneers to form plywood still several steps only to be carried out by hand, e.g. B. the sorting of veneer layers and the introduction of the adhesive layers or the application of the adhesive in liquid form on the veneer layers. The reference to the Production of molded plywood plays a role here because with the method presented here in structure and form similar Moldings can be produced and since the production without changing the technology, with customized settings, can be done on the same tools as molded plywood, which prepared the pressing tools in the manner known in the art and can be manufactured.
Aufgabe der Erfindung ist es auch unter anderem, ein Problem der ästhetischen Art zu lösen, nämlich den Mangel an optischer und haptischer Qualität der üblichen mit Melamin beschichteten Formsperrholzteile bzw. der vollständig aus Kunststoff hergestellten Objekte, insbesondere im Bereich Möbel und Innenarchitektur. Ziel war es also, ein Material und einen Herstellungsprozess anzubieten, die einerseits die mechanischen Anforderungen wie Sperrholz oder Kunststoff für verschiedene Anwendungen erfüllen können, gleichzeitig jedoch die Verwendung von Kunststoff drastisch reduzieren und eine dem Papier nicht unähnliche samtige Oberflächenqualität ermöglichen.The object of the invention is, inter alia, to solve a problem of the aesthetic nature, namely the lack of optical and haptic quality of the usual melamine-coated molded plywood parts or the objects made entirely of plastic, especially in the field of furniture and interior design. The aim was therefore to offer a material and a manufacturing process, on the one hand, the mechanical requirements such as plywood or plastic for various users However, at the same time drastically reduce the use of plastic and allow a not insignificant velvety surface quality paper.
Das erfindungsgemäße Verfahren bietet gegenüber Formsperrholz verschiedene Verbesserungen und neue Möglichkeiten für die Herstellung von Formteilen: das Ausgangsmaterial ist kostengünstiger als Furnier, gleichbleibende Qualität in großen Mengen kann seitens der Papierindustrie leichter gewährleistet werden und die spezifischen Eigenschaften können dem jeweiligen Verwendungszweck angepasst werden. Die Vorproduktion, Handhabung und Sortierung der Lagen wird erleichtert, könnte leicht automatisiert werden und sehr präzise erfolgen. Somit können Produktionsabfälle und Ausschuss reduziert werden. Es reduzieren sich auch der Aufwand für Qualitätskontrolle, für Lagerhaltung und Transport. Geringere Herstellungskosten und eine geringere Umweltbelastung ergeben sich auch durch Zeit- und Energieeinsparungen. Temperatur, Druck und vor allem Haltezeit im Werkzeug sind deutlich niedriger im Vergleich zu formgepresstem Furnier. Das Aufbringen von Klebstoffen entfällt als Arbeitsschritt. Ein Nachteil gegenüber Formsperrholz muss erwähnt werden, nämlich die etwas geringere Härte der Form und der Oberfläche. Demgegenüber steht eine große Bandbreite an neuen Möglichkeiten in Bezug auf visuelle und haptische Qualität der Oberflächen und der Schnittkanten, da das Material im Endprodukt sowohl Ähnlichkeit mit Papier als auch mit Kunststoff besitzt und z. B. viele Farbvarianten einfach realisiert werden können. Weiterhin kann das erhaltene Endprodukt leicht in existierende Recyclingprozesse, wie z. B. für Getränkekartons, überführt werden.The inventive method offers Molded plywood different improvements and new possibilities for the production of molded parts: the starting material is cheaper than veneer, consistent quality in large quantities can be easier on the part of the paper industry be assured and the specific characteristics can be adapted to the respective purpose. The pre-production, handling and sorting of the layers is facilitated could be easily automated and very accurate respectively. Thus, production waste and Committee be reduced. It also reduces the effort for quality control, for warehousing and Transport. Lower production costs and lower environmental impact also result from time and energy savings. Temperature, pressure and especially holding time in the tool are significantly lower in comparison to form-pressed veneer. The application of adhesives is eliminated as a work step. A disadvantage compared to molded plywood needs be mentioned, namely the slightly lower hardness the shape and the surface. In contrast stands a wide range of new opportunities in Reference to visual and haptic quality of the surfaces and the cut edges, since the material in the final product is both similar has paper as well as plastic and z. B. many color variants easy can be realized. Furthermore, the obtained End product easily in existing recycling processes, such. For example Beverage cartons, to be transferred.

Das erfindungsgemäße Verfahren hat durch die Verarbeitung vorsortierter Lagen den Vorteil technisch einfach und sehr flexibel zu sein. Auch der Einsatz von verschiedenen Lagen aus unterschiedlichen Materialien mit unterschiedlichen optischen und mechanischen Eigenschaften ermöglicht eine einfach an verschiedene Anwendungen angepasste Produktion. Obwohl das Recycling als resourcenschonend und umweltfreundlich gelten kann, entfallen beim erfindungsgemäßen Verfahren der Transport- und Energieaufwand für Recyclingprozess und Vorproduktion bis zur endgültigen Pressung. Weiterhin unterscheidet sich das Endprodukt des erfindungsgemäßen Verfahrens optisch und haptisch sehr stark von diesem Recyclingprodukt und bietet in einem einzigen Arbeitsschritt mehr verschiedene Möglichkeiten der Gestaltung und damit auch der Anwendung. In Bezug auf die Möglichkeiten für dreidimensionale Formen unterliegt das flächige Kartonmaterial wegen Faltenbildung allerdings größeren Einschränkungen, entsprechend denen bei Formsperrholz. Andererseits bietet die Verwendung von geschichtetem Flächenmaterial z. B. eine viel einfachere Kontrolle über die resultierende Materialstärke.The inventive method has by the processing presorted layers the advantage technically simple and very flexible to be. Also, the use of different layers of different materials with different optical and mechanical properties an easily adapted to different applications production. Although recycling as resource-saving and environmentally friendly may apply, omitted in the invention Method of transport and energy consumption for recycling process and pre-production until the final pressing. Farther differs the final product of the invention Process optically and haptically very strong of this recycled product and offers more different possibilities in a single step Design and thus also the application. In terms of possibilities for three-dimensional forms subject to the flat Cardboard material, however, larger because of wrinkling Restrictions, corresponding to those of molded plywood. On the other hand, the use of layered sheet material offers z. For example, much easier control over the resulting Material thickness.
Des weiteren ist neu, dass erfindungsgemäß das teilweise Schmelzen der Kunststoffschichten auf den Außenseiten der Formteile zur Erzeugung einer fertigen Oberfläche genutzt wird die sowohl mechanisch als auch optisch und haptisch zufriedenstellend ist.Furthermore, it is novel that, according to the invention, the partial melting of the plastic layers on the outer sides of the molded parts is used to produce a finished surface which is satisfactory both mechanically and optically and haptically is.
