Abstract
To produce a plastic coating for objects with hard surfaces, for example furniture, a cellulose-acetate or celluloid foil is treated with a liquid having the following components: 70 to 90 preferably 80 parts by volume of spirit, 5 to 15 preferably 10 parts by volume of water, 10 to 20 parts by volume of acetone and, on the basis of 100 liters of liquid, 100 to 200 preferably 150 g of camphor. Next, the treated foil is applied with a slight pressure to the object, and then allowed to dry.
Description
Verfahren zur Herstellung einer Kunststoffbeschichtung Process for the production of a plastic coating
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Kunststoffbeschichtung für Gegenstände mit harten Oberflächen, z.B. Möbel.The invention relates to a method for producing a plastic coating for objects with hard surfaces, e.g. Furniture.
Die Kunststoffbeschichtung von Gegenständen mit harten Oberflächen, z.B. Platten für den Mobelbau, erfolgt bisher im Wesentlichen dadurch, daß Kunststoffolien auf die ebenen Flächen der Platten aufgeklebt werden. Auf die freibleibenden Seitenflächen müssen Umleimer aufgebracht werden. Auf diese Art ist es nur möglich, völlig ebene Flächen zu beschichten, wobei an den Kanten ein deutlicher Übergang sichtbar ist und es überdies an den Kanten, z.B. zufolge des Einflusses von Feuchtigkeit, leicht zu Ablösungen kommen kann.The plastic coating of objects with hard surfaces, e.g. Sheets for furniture construction have so far essentially been made by gluing plastic films onto the flat surfaces of the sheets. Edging must be applied to the free side surfaces. In this way it is only possible to coat completely flat surfaces, whereby a clear transition is visible at the edges and it is also at the edges, e.g. due to the influence of moisture, detachments can easily occur.
Bei einem anderen weniger angewendeten Verfahren werden Kunststoffolien durch Tiefziehen becherartig verformt und auf die Platten aufgeschoben. Hiefür ist jedoch für jede Plattengröße ein eigenes Tiefziehwerkzeug erforderlich und überdies kann auch mit diesem Verfahren der Gegenstand nicht völlig umhüllt werden. Eine völlige Umhüllung mit einer Kunststoffschicht war bisher nur durch Kunststofflacke möglich, Lackierungen sind jedoch sehr arbeitsaufwendig.In another less used method, plastic films are deformed in a cup-like manner by deep drawing and pushed onto the plates. For this, however, a separate deep-drawing tool is required for each plate size and, moreover, the object cannot be completely encased with this method either. A complete covering with a plastic layer was previously only possible with plastic lacquers, but lacquering is very labor intensive.
Die Erfindung hat es sich vor allem zum Ziel gesetzt, ein Verfahren zu schaffen, mit Hilfe dessen es möglich ist, eine Kunststoffbeschichtung herzustellen, die einfach aufzubringen ist, wobei ein Aufbringen auch über Kanten und Rundungen bzw. Erhöhungen und Vertiefungen möglich sein soll. Erreicht wird dieses Ziel dadurch, daß eine aus Cellulose-Acetat bzw. Zelluloid hergestellte Folie mit einer Flüssigkeit behandelt wird, die besteht aus: 70 bis 90, vorzugsweise 80 RT Spiritus, 5 bis 15, vorzugsweise 10 RT Wasser, 10 bis 20 RT Aceton sowie, bezogen auf 100 1 Flüssigkeit, 100 bis 200, vorzugsweise 150 g Kampfer, daß die so behandelte Folie unter leichtem Druck auf bzw. um den Gegenstand aufgebracht und anschließend trocknen gelassen wird.The primary object of the invention is to provide a method by means of which it is possible to produce a plastic coating that is easy to apply, and that it should also be possible to apply it over edges and curves or elevations and depressions. This goal is achieved by treating a film made from cellulose acetate or celluloid with a liquid which consists of: 70 to 90, preferably 80 RT alcohol, 5 to 15, preferably 10 RT water, 10 to 20 RT acetone and, based on 100 l of liquid, 100 to 200, preferably 150 g of camphor, that the film thus treated is applied to or around the object under slight pressure and then left to dry.
Zweckmäßig werden der Flüssigkeit einige Tropfen Amylacetat zugesetzt.
Eine Flüssigkeit zur Behandlung von Acetatfolien für Kunststoffbeschichtungen zeichnet sich demnach erfindungsgemäß dadurch aus, daß sie besteht aus: 70 bis 90, vorzugsweise 80 RT Spiritus, 5 bis 15, vorzugsweise 10 RT Wasser, 10 bis 20 RT Aceton sowie, bezogen auf 100 1 Flüssigkeit, 100 bis 200, vorzugsweise 150 g Kampfer.It is advisable to add a few drops of amyl acetate to the liquid. A liquid for the treatment of acetate films for plastic coatings is therefore distinguished according to the invention in that it consists of: 70 to 90, preferably 80 RT alcohol, 5 to 15, preferably 10 RT water, 10 to 20 RT acetone and, based on 100 1 liquid , 100 to 200, preferably 150 g camphor.
Nachstehend ist die Erfindung an Hand eines Ausführungsbeispieles näher beschrieben, ohne jedoch auf dieses Beispiel beschränkt zu sein.The invention is described in more detail below on the basis of an exemplary embodiment, but without being restricted to this example.
Um die in der Zeichnung im Schnitt dargestellte Platte 1 mit einer Kunststoffbeschichtung zu versehen, wird vorerst eine Flüssigkeitsmischung hergestellt, die aus 78 Raumteilen Spiritus, 8 Raumteilen Wasser, 14 Raumteilen Aceton und 150 g Kampfer besteht. Dieser Flüssigkeit werden einige Tropfen Amylacetat zugesetzt. Nunmehr wird in die Flüssigkeitsmischung eine der Platte 1 entsprechend zugeschnittene Acetatfolie 2 gelegt, die unter dem Handelsnamen "ULTRAPHAN" (hergestellt von der LONZA -Werke GmbH) im Handel erhältlich ist.In order to provide the plate 1 shown in section in the drawing with a plastic coating, a liquid mixture is first of all made up of 78 parts alcohol, 8 parts water, 14 parts acetone and 150 g camphor. A few drops of amyl acetate are added to this liquid. An acetate film 2 which is cut to size for the plate 1 is now placed in the liquid mixture and is commercially available under the trade name "ULTRAPHAN" (manufactured by LONZA -Werke GmbH).
Die ULTRAphan Acetatfolie wird aus 2,5 Zellulose-Acetat unter Zusatz von Weichmachern im Gießverfahren hergestellt und ist eine Hartfolie mit hoher Steifigkeit. Die technischen Daten dieser Folie sind nachstehender Tabelle zu entnehmen.The ULTRAphan acetate film is made from 2.5 cellulose acetate with the addition of plasticizers in a casting process and is a hard film with high rigidity. The technical data for this film can be found in the table below.
Technische DatenTechnical specifications

Durch die Behandlung mit der oben beschriebenen Flüssigkeit wird die Hartfolie derart leicht verformbar, daß sie über die Flächen einschließlich der Rundungen und Kanten der Platte 1 gelegt werden kann. Die Folie 2 passt sich dabei auch Erhebungen 3 bzw. Vertiefungen 4,
wie sie in der Zeichnung strichliert angedeutet sind, an.The treatment with the liquid described above makes the hard film so easily deformable that it can be placed over the surfaces including the curves and edges of the plate 1. The film 2 also fits elevations 3 or depressions 4, as indicated by dashed lines in the drawing.
Dieses Überziehen des Gegenstandes bzw. die Eigenschaften der durch die erfinclungsgemäße Flüssigkeit weich gemachten Folie könnte mit einem ausgezogenen Teigband verglichen werden, wie es zur Herstellung von Strudeln verwendet wird.This covering of the object or the properties of the film softened by the liquid according to the invention could be compared to a pulled-out dough sheet as used for the production of strudel.
Die noch freibleibende Fläche der Platte l kann mit einer gleichartig vorbehandelten Folie 5 beschichtet werden.The remaining free surface of the plate 1 can be coated with a similarly pretreated film 5.
Nach einer Trocken- bzw. Ruhezeit von etwa 2 bis 3 Stunden kann das Werkstück montiert werden bzw. ist zu weiteren mechanischen Bearbeitungen, z.B. Bohren oder Sägen geeignet.After a drying or resting time of about 2 to 3 hours, the workpiece can be assembled or is ready for further mechanical processing, e.g. Suitable for drilling or sawing.
Ein erfindungsgemäß beschichtetes Werkstück zeichnet sich durch Wetterfestigkeit, Lichtechtheit, Säurebeständigkeit, Unbrennbarkeit und auch durch eine hohe Durchschlagsfestigkeit gegenüber elektrischem Strom aus. Mittels des erfindungsgemäßen Verfahrens können Werkstücke bzw. Gegenstände aus verschiedenen Materialien und mit den verschiedensten Formen beschichtet werden. So ist es z.B. möglich, völlig unregelmäßig geformte Steine zu beschichten, es kann aber auch Glas und Metall beschichtet werden. Die Erfindung ist nicht auf das beschriebene Ausführungsbeispiel beschränkt, vielmehr kann insbesondere die zur Behandlung der Acetatfolien verwendete Flüssigkeit in ihrer Zusarrmensetzung im Rahmen der in den Ansprüchen angegebenen Grenzen verändert werden, wobei noch brauchbare Ergebnisse erzielt werden. Auch ist die Erfindung nicht auf 2,5 Cellulose - Acetatfolien beschränkt. Es kennen auch andere Celluloseacetatfolien bzw. Zelluloidfolien verwendet werden.

Using the method according to the invention, workpieces or objects made of different materials and with a wide variety of shapes can be coated. So it is e.g. possible to coat completely irregular shaped stones, but it can also be coated with glass and metal. The invention is not limited to the exemplary embodiment described, but in particular the composition of the liquid used for the treatment of the acetate films can be changed within the limits specified in the claims, whereby still usable results are achieved. The invention is also not limited to 2.5 cellulose acetate films. Other cellulose acetate films or celluloid films are also known to be used.
