Abstract
Description
Verfahren zur Herstellung von geprägten Plastikfolien und dergl.Process for the production of embossed plastic films and the like.
Die Erfindung betrifft ein Verfahren zur Herstellung von glänzenden bis hochglänzenden Kunststoff-Folien, Kunstleder und Syntheseleder mit Flächendessinierung.The invention relates to a method for producing shiny to high-gloss plastic foils, artificial leather and synthetic leather with surface patterning.
Beim Formen von Kunststoff-Folien, Kunstleder und Kunststoffplatten unter Verwendung von Formen, die Luftdurchlässe haben, durch die Luft aus der Form entweichen kann oder abgesaugt wird, werden auch die Bohrungen auf dem Fertigteil markiert.When molding plastic foils, artificial leather and plastic sheets using molds that have air passages through which air can escape from the mold or is sucked out, the Holes marked on the precast part.
TIm nach diesem Prinzip vollkommene Abformungen der Matrize zu erzielen, müssen alle Vertiefungen Anschluß an das Vakuum oder Entweichmöglichkeiten für die Luft haben, da nur dann ein vollkommenes Ausfüllen der Formhöhlungen stattfindet.To achieve perfect impressions of the matrix according to this principle, all wells must have a connection to the vacuum or escape possibilities for the air, since only then can they be completely filled the mold cavities takes place.
Beim Prägen von Folien-, Synthese-, oder Kunstlederoberflächen müssen die Poren in der Matrize mikroskopisch klein sein, damit die Details der Naturvorlage ohne Verzerrung wiedergegeben werden. Die Mitformung dieser Mikroporen ergibt eine matte Oberfläche.When embossing foil, synthetic or synthetic leather surfaces, you have to the pores in the die must be microscopic so that the details of the natural pattern can be reproduced without distortion. The participation these micropores result in a matt surface.

Eine glänzende bzw. hochglänzende Oberfläche ist beim Prägen oder . Vakuumprägen oftmals erwünscht. Im Falle von glatter Hochglanzware, die einen hohen Anpreßdruck verträgt, wird mittels hochglanzpolierter, verchromter Prägewalzen die heiße Ware geprägt.A glossy or high-gloss surface is when embossing or. Vacuum embossing is often desirable. In the case of smooth, high-gloss goods that can withstand high contact pressure, high-gloss polished, chrome-plated embossing rollers embossed the hot goods.
Im Falle von Dessins mit Tiefendifferenz ist es äußerst schwierig und teuer, Walzen herzustellen, die polierte Flächen aufweisen. Solche Walzen sind dazu kaum rein genug zu halten, um einen guten Glanz zu erzielen. In der Praxis wird Hochglanzkunstleder oder Folie so hergestellt, daß zuerst Ware mit glatter Hochglanzoberfläche-rhergestellt wird, die dann in einem zweiten Arbeitsgang mit einer erhitzten Dessinwalze auf kalte Ware überprägt wird oder mit kalter Walze auf erhitzter Ware.In the case of designs with a difference in depth, it is extremely difficult and expensive to produce rollers that have polished surfaces. Such Rollers can hardly be kept clean enough to achieve a good gloss. In practice, high-gloss synthetic leather or foil is produced in such a way that that goods with a smooth, high-gloss surface were first produced which is then embossed in a second operation with a heated design roller on cold goods or with a cold roller heated goods.
Die Dessinwalze ist für diesen Zweck in den Flächen sehr tief graviert, damit diese die Warenoberfläche nicht berühren. Diese Arbeitsweise ist umständlich, teuer und führt zu Differenzen im Aussehen der Ware. Die tiefgravierte Walze ist in den meisten Fällen nur für das Uberprägen verwendbar.The design roller is engraved very deeply in the surfaces for this purpose, so that they do not touch the surface of the goods. This way of working is cumbersome, expensive and leads to differences in the appearance of the goods. In most cases, the deeply engraved roller can only be used for embossing.
Durch die Erfindungssoll die Aufgabe gelöst werden, Kunstleder, Kunststoff-Folien und dergl. mit ein und der-selben Walze oder dem gleichen Prägezylinder sowohl matt, halbmatt oder hochglänzend zu prägen.The object of the invention is to be achieved, artificial leather, plastic films and the like. With one and the same roller or the same Embossing cylinder both matt, semi-matt or high-gloss.
Zur Lösung dieser gestellten Aufgabe wird erfindungsgemäß vorgeschlagen, die Warenoberfläche mit einer dünnen Lackschicht zu versehen, deren Erweichungsbereich wesentlich höher liegen muß als der des BescMchtungsmaterials, bzw. mit einem unplastifizierbaren Lackfilm.· Die Schichtstärke des Lackfilms soll dabei so bemessen sein, daß sieTo solve this problem, it is proposed according to the invention that to provide the surface of the goods with a thin layer of lacquer, the softening range of which must be significantly higher than that of the covering material, or with an unplasticizable paint film. · The thickness of the paint film should be such that it

nicht in die feinen Poren eindringt, sonst jedoch die gesamte Verformung Mitmacht.does not penetrate into the fine pores, but otherwise the entire deformation Participate.
Unterstützend wird bei diesem Verfahren die Ware vornehmlich von der Rückseite erhitzt, um das plastizifizierbare Beschichtungsmaterial gut zu durchwärmen·In this process, the goods are primarily supported by the The rear side is heated in order to warm the plasticizable coating material thoroughly
Zur Unterstützung des Temperaturunterschiedes an der Ware kann unmittelbar in den Spalt zwischen Walze und Ware vor der Kontaktlinie kalte Luft eingeblasen werden, die die Temperatur der Warenoberfläche unmittelbar vor dem Kontakt mit der Walze verringert.To support the temperature difference on the goods, directly Cold air is blown into the gap between the roller and the goods in front of the contact line, which directly increases the temperature of the surface of the goods decreased before contact with the roller.
Der Lackfilm kann nach allen üblichen Verfahren aufgetragen sein. Zur Erzielung besonderer Mustereffekte kann der Lackfilm klar oder eingefärbt als Muster aufgetragen werden, so daß nach dem Prägen eine genarbte mattglänzende Musterung entsteht, obwohl nur eine matte Walze verwendet wird.The paint film can be applied by any conventional method. To the To achieve special pattern effects, the lacquer film can be applied clear or colored as a pattern, so that a grained one after embossing matt-glossy pattern is created even though only a matt roller is used.
Als Lacke bewähren sich solche auf Acrylatbasis (Plex 331* 335), Einkomponenten-Polyurethanbasis und Zweikomponenten-Polyurethanbasis, z.B. Baygenlack auf Polyurethanbasis oder auf Impramil-LKU + kk5k + ^389-Basis oder Zweikomponenten-Quinnlacke auf Polyurethanbasis (QT-1O-A+QT 11) und Copolymerlacke QL 5038, Q 7019 usw.Acrylate-based (Plex 33 1 * 335), one-component polyurethane-based and two-component polyurethane-based, e.g. Baygen varnish based on polyurethane or Impramil-LKU + kk5k + ^ 389-based or two-component Quinn varnish based on polyurethane (QT-1O- A + QT 11) and copolymer coatings QL 5038, Q 7019 etc.
