Description

Verfahren zur Herstellung von mit gießbarem Kunststoff umhüllten Gegenständen Die Erfindung betrifft ein Verfahren zur Herstellung von mit gießbarem Kunststoff allseitig umhüllten Gegenständen, bei welchem ein Holzkern in eine dem herzustellenden Gegenstand entsprechende Hohlform eingelegt und durch Distanzstücke aus dem gleichen Kunststoff abgestützt wird, und besteht darin, daß der Holz- oder Holzfaserkern in einer mit Zu- und Ableitungen für die Kunststoffmasse versehene Hohlform mittels auf den Holzkern aufgebrachten und angehärteten Kunststoffmassetröpfchen distanziert und sodann von der durch die Hohlform hindurchfließenden Kunststoffmasse unter mindestens teilweiser Auflösung der Kunststoffmassetröpfchen vollständig umhüllt wird. Process for the production of encased with castable plastic Objects The invention relates to a method for making with castable Objects encased in plastic on all sides, in which a wooden core is inserted into one of the The object to be produced is inserted into the corresponding hollow shape and separated by spacers is supported from the same plastic, and consists in that the wooden or Wood fiber core in one with inlet and outlet lines for the plastic compound Hollow form by means of droplets of plastic compound applied and hardened to the wooden core distanced and then from the plastic mass flowing through the hollow mold completely enveloped with at least partial dissolution of the plastic mass droplets will.

Weitere Merkmale der Erfindung sind die besondere Wärmezufuhr und Druckgebung in der Hohlform, die zweckmäßigerweise zwischen heizbare - Platten einer Presse gelegt wird. Further features of the invention are the special heat supply and Pressure in the hollow mold, which is expediently between heatable - plates a Press is placed.

Zur Herstellung des Kernes oder von Kernteilstückchen können unbearbeitetes, minderwertiges Holz oder Holzfaserstücke verwendet werden, die durch das erfindungsgemäße Verfahren in einem Arbeitsgang zu hochwertigen Endprodukten für die Bau- und Möbelindustrie, z. B. Tischplatten, Fensterrahmen und -stöcke, Türen, Regale, Reklameschilder, Möbel und Möbelteile, Bauelemente, verwandelt werden. For the production of the core or core pieces, unprocessed, Inferior wood or pieces of wood fiber are used by the inventive One-step process for high-quality end products for the construction and furniture industry, z. B. Table tops, window frames and frames, doors, shelves, billboards, furniture and furniture parts, structural elements, are transformed.

Es sind bereits Verfahren zur Umhüllung kleiner Nutz- oder Ziergegenstände, wie Brillenbügel oder Dekorationsmaterial, bekannt, welche in einer Hohlform durch Distanzstücke aus dem Gußkunststoff distanziert werden und durch den eingegossenen flüssigen Kunststoff ummantelt werden. Hierbei werden jedoch die Distanzstücke vorgeformt und zur Abstützung mit dem Kernstück etwa dadurch verbunden, daß sie als Fixierscheiben auf das Kernstück aufgefädelt werden. There are already processes for wrapping small useful or decorative objects, such as eyeglass temples or decoration material, known, which in a hollow shape through Spacers are distanced from the cast plastic and cast by the encased in liquid plastic. Here, however, the spacers are preformed and connected for support with the core piece, for example, in that they act as fixing washers be threaded onto the core.

Um jedoch größere Gegenstände, wie Tischplatten oder Fensterrahmen, die im Durchfluß von flüssiger Kunststoffmasse allseitig ummantelt werden sollen, abstützen zu können, müssen hierzu die Distanztröpfchen mit dem Kern fest verbunden werden, ohne daß nach vollzogener Umhüllung unbedeckte Stellen am Holzkern verbleiben. Nur dadurch, daß die Umhüllung der Holzkerne allseitig ohne jegliche Unterbrechung vollzogen ist, wird der umhüllte Holzkern den atmosphärischen Einflüssen entzogen und dadurch witterungsfest. However, to move larger objects, such as table tops or window frames, which are to be encased on all sides in the flow of liquid plastic compound, To be able to support, the spacer droplets must be firmly connected to the core without leaving uncovered areas on the wood core after the wrapping has been completed. Only by the fact that the casing of the wooden cores on all sides without any interruption is completed, the encased wooden core is withdrawn from atmospheric influences and therefore weatherproof.

Nach dem erfindungsgemäßen Verfahren können marktreife Fertigerzeugnisse aus billigen Holzmaterialien in wenigen Minuten hergestellt werden, wobei die vollständige Umhüllung des Holzkernes mit gießfähigem Kunststoff mit einem einzigen Durchfluß ermöglicht wird. Diese Fertigerzeugnisse sind nicht nur witterungsfest, sondern auch weitgehendst schlag-, kratz-, säuren- und laugenfest und bedürften keiner altherbekannten Nachpflege mehr, wie Anstrich und Polituren. Im selben einzigen Fertigungsgang können die Erzeugnisse gegebenenfalls auch mit andersfarbigen Musterungen, Zeichnungen, Ornamenten und Dekorationen versehen werden, was z. B. durch Auftragen von Kunststoffmassetröpfchen auch auf die Innenwandungen der Hohlform erzielt werden kann. Finished products ready for the market can be produced by the method according to the invention can be made from cheap wooden materials in minutes, with the full Enveloping the wood core with castable plastic with a single flow is made possible. These finished products are not only weatherproof, but also largely impact, scratch, acid and alkali-resistant and do not require any well-known ones Aftercare more like painting and polishing. Can in the same single production run the products, if necessary, with patterns, drawings of different colors, Ornaments and decorations are provided, which z. B. by applying plastic mass droplets can also be achieved on the inner walls of the hollow mold.

Einer der Hauptvorzüge des erfindungsgemäßen Verfahrens liegt darin, daß die in der Holzeinschnittindustrie zwangsweise anfallenden minderen Brettqualitäten ohne kostspielige Bearbeitung zu wertvollen, absolut witterungsfesten Marktartikeln verwandelt werden. One of the main advantages of the method according to the invention is that that the inevitably occurring in the wood cutting industry inferior board qualities without costly processing into valuable, absolutely weatherproof market items be transformed.

Das erfindungsgemäße Verfahren wird nachstehend an Hand der Zeichnung in mehreren Ausführungsbeispielen näher erläutert, aus denen auch weitere Merkmale dieses Verfahrens zu entnehmen sind. In der Zeichnung ist in Fig. la ein Holzkernteil aus einem Stück rohem, gattergesägtem Holzrohling, in Fig.lb ein Kernteil mit aufgetragenen Kunststoffmassetröpfchen und in Fig. lc ein Kernteil nach der vollzogenen Kunststoffumhüllung schematisch im Querschnitt dargestellt; Fig. 2 zeigt im Querschnitt einen aus mehreren Teilen bestehenden Holzkern nach der Kunststoffumhüllung; Fig. 3 zeigt im Querschnitt einen Fensterrahmenteil, welcher aus einem aus zwei Teilen bestehenden Holzkern besteht, nach der Kunststoffumhüllung in der entsprechend profilierten Hohlform; Fig. 4 zeigt eine schematische Darstellung einer Anlage zur Ausübung des Verfahrens. The method according to the invention is described below with reference to the drawing explained in more detail in several exemplary embodiments, from which also further features can be found in this procedure. In the drawing, a wooden core part is shown in FIG from a piece of raw, frame-sawn wooden blank, in Fig.lb a core part with applied Plastic mass droplets and, in FIG. 1c, a core part after the plastic coating has been completed shown schematically in cross section; Fig. 2 shows in cross section one of several Divide existing wood core after the plastic coating; Fig. 3 shows in cross section a window frame part, which consists of one consisting of two parts Wood core consists, after the plastic casing in the correspondingly profiled hollow shape; 4 shows a schematic representation of a system for carrying out the method.

Als Ausgangsprodukt dient ein aus rohen Holzteilen (minderwertige Bretter) oder aus Holzfasermaterial hergestellter Kern 1, dessen Oberfläche zweckmäßigerweise noch besonders aufgerauht wird, um möglichst viele frei stehende Oberflächenfasern 2 zu erhalten, welche die Haftfähigkeit der Kunststoffmasse vergrößern. The starting product is made from raw wooden parts (inferior Boards) or core 1 made of wood fiber material, the surface of which is expediently is still particularly roughened in order to have as many free-standing surface fibers as possible 2, which increase the adhesiveness of the plastic compound.

Der Holzkern kann auch (wie dies Fig. 2 zeigt) aus mehreren Teilen 1 bestehen, die bei ungleicher Stärke vor dem Einlegen in die Hohlform auf annähernd gleiche Stärke gewalzt oder gepreßt und miteinander durch Klammerhaftung, Nagelung oder lose Vernutung zu einem Kernstück verbunden werden können. Der auf diese einfache Weise hergestellte rohe Holzkern wird nun in eine Dauerhohlform eingelegt, welche die Abmessung des gewünschten Fertigartikels aufweist. Um nun die allseitige Distanzierung des Kernstückes von der Hohlforminnenwand zu erzielen, werden auf das Kernstück 1 (Fig.lb) Kunststoffmassetröpfchen 3 des Umhüllungskunststoffes in weichem Zustand aufgetragen und angehärtet, so daß diese bereits nach wenigen Minuten einerseits als feste Distanzkörper zwischen Hohlform und Kernstück Verwendung finden, andererseits aber, da sie auf dem Kern festhaften, beim nachfolgenden Durchfluten der Umhüllungskunststoffmasse durch die Hohlform von der Kunststoffmasse nicht weggespült werden können. Diese Distanzkunststoffmassetröpfchen werden nach kurzer Zeit der Durchflutung angelöst bzw. zum Teil aufgelöst, so daß das Kernstück nach der Durchflutung und Füllung der Hohlform in seinem ganzen Umfang allseitig mit Kunststoff umhüllt ist. The wood core can also (as FIG. 2 shows) consist of several parts 1 exist, which in the case of unequal thickness before inserting into the hollow mold to approximately same thickness rolled or pressed and together by stapling, nailing or loose Vernutung can be connected to a core piece. The one on this simple Wise made raw wood core is now placed in a permanent hollow form, which has the dimensions of the desired finished article. Now to the all-round distancing to achieve the core piece from the hollow mold inner wall, are on the core piece 1 (Fig.lb) plastic mass droplets 3 of the enveloping plastic in a soft state applied and hardened, so that this on the one hand after a few minutes As a solid spacer between the hollow form and the core use, on the other hand but, since they adhere firmly to the core, during the subsequent flooding of the encasing plastic compound cannot be washed away by the plastic mass through the hollow shape. These Distance plastic mass droplets are loosened after a short period of flooding or partially dissolved, so that the core after the flooding and filling the hollow form is encased on all sides with plastic in its entire circumference.

Nach dem Einlegen des mit Distanzkunststoffmassetröpfchen3 versehenen Holzkernesl wird die teilbare Hohlform 5, 5 a (Fig. 3) oder 13 (Fig. 4) luftdicht verschlossen und unter Vakuum gesetzt, so daß mit der Verdünnung der Luftdichte in der Hohlform auch Teile der Holzfeuchtigkeit entzogen werden und auch die Luftdichte in den Holzkapillaren verringert wird. Dadurch wird beim Aufheizen der Hohlform und damit verbundenen Erwärmung des Holzrohlings und somit eintretender Luftausdehnung in diesem das Entstehen von Luftblasen in der Kunststoffumhüllung verhindert. After inserting the spacer plastic mass droplets3 Holzkernesl the divisible hollow form 5, 5 a (Fig. 3) or 13 (Fig. 4) is airtight sealed and placed under vacuum, so that with the dilution of the air density In the hollow form, parts of the wood moisture and also the air density are withdrawn is decreased in the wooden capillaries. This is when the mold is heated and the associated heating of the wood blank and thus occurring air expansion in this the formation of air bubbles in the plastic casing is prevented.

Die zweckmäßigerweise zwischen heizbaren Platten gelegte Hohlform wird mittels Druck mit Kunststoffmasse gefüllt, bis die Kunststoffmasse durch die gegenüberliegende Überlauföffnung wieder austritt. The hollow form expediently placed between heatable plates is filled with plastic compound by means of pressure until the plastic compound passes through the opposite overflow opening emerges again.

Die eingedrückte Kunststoffmasse 4 fließt in die vorhandenen Hohlräume zwischen dem Holzrohling 1 und der Hohlform 5, 5 a oder 13 sowie auch in die Zwischenräume des Holzrohlings bzw. in dessen Unebenheiten, Risse, Fugen, Ast- und Wurmlöcher.The pressed-in plastic compound 4 flows into the existing cavities between the wooden blank 1 and the hollow shape 5, 5 a or 13 and also in the spaces of the wooden blank or in its unevenness, cracks, joints, knots and wormholes.

Außerdem werden die Distanzkunststoffmassetröpfchen 3 von der durchflutenden Kunststoffmasse umspült und verschmelzen bei der folgenden Aushärtung der Kunststoffmasse mit dieser unsichtbar und homogen.In addition, the distance plastic mass droplets 3 of the flowing through Plastic compound washes around and melts during the subsequent hardening of the plastic compound with this invisible and homogeneous.

Nunmehr wird der Hohlform 5, 5 a oder 13 so viel Wärme zugeführt, daß die Aushärtung der Kunststoffmasse früher erfolgt, bevor das im Holzrohling 1 befindliche Wasser (Feuchtigkeit) verdampft bzw. die Naturharze flüssig werden. Nach erfolgter Aushärtung kann das gebrauchsfertige Endprodukt aus der Hohlform herausgenommen und ohne weitere Nachbearbeitung seinem Bestimmungszweck zugeführt werden. Now the hollow form 5, 5 a or 13 is supplied with as much heat as that the hardening of the plastic compound takes place earlier, before that in the wooden blank 1 Any water (moisture) present evaporates or the natural resins become liquid. After curing, the ready-to-use end product can be removed from the hollow mold taken out and supplied to its intended use without further processing will.

Die in Fig. 4 dargestellte Anlage besteht aus einer trichterartigen Einfüllvorrichtung 9, einem Mischbehälterl0 für die Kunststoffumhüllungsmasse, einem Druckbehälter 12, aus welchem mittels eines vom Kompressorll erzeugten Druckes die gleichmäßig vermischte Kunststoffmasse durch das Einlaßventil 13 a in die Dauerhohlform 13 gepreßt wird, während die überschüssige Kunststoffmasse durch das diagonal gegenüberliegende Auslaßventill3b in den Absatzbehälter 14 geleitet wird, welcher mit einer Vakuumvorrichtung 15 verbunden ist, mittels der in der Hohlform 13 Luftleere erzeugt wird. Die Hohlform 13 wird mittels Heizplatten beheizt. The system shown in Fig. 4 consists of a funnel-like Filling device 9, a mixing container l0 for the plastic wrapping compound, a Pressure vessel 12, from which by means of a pressure generated by the Kompressorll the evenly mixed plastic mass through the inlet valve 13 a into the permanent hollow form 13 is pressed, while the excess plastic mass through the diagonally opposite Auslaßventill3b is passed into the paragraph container 14, which with a vacuum device 15 is connected, by means of which a vacuum is generated in the hollow mold 13. The hollow form 13 is heated by means of heating plates.

Das Verfahren ist ebensowohl wegen seines Verbrauchs an billigem Rohmaterial, seiner Einfachheit und kurzen Herstellungszeiten und der Erzielung sofort marktfähiger Fertigware besonders wirtschaftlich. The process is also cheap because of its consumption Raw material, its simplicity and short manufacturing times and achievement Immediately marketable finished goods particularly economical.
