Abstract
Description
Die Erfindung betrifft ein Verfahren zum Bedrucken von thermoplastischen Kunststoffen mit Thermodiffusionsfarbstoffen durch Transferdruck sowie die vorteilhafte Verwendung der durch dieses Verfahren hergestellten Produkte.The invention relates to a method for printing thermoplastic Plastics with thermal diffusion dyes Transfer printing as well as the advantageous use of this Processed products.
Aus der DE-OS 2 731 121 ist es bekannt, thermoplastische Kunststoffe wie Polyethylen dadurch zu bedrucken, daß die zu bedruckende Seite des Polyethylenformkörpers unter Wärmeeinwirkung und dadurch bewirkten Aufschmelzen mit einem Druckträger, wie einem mit Thermodiffusionsfarbstoffen versehenen Papierträger, in Kontakt gebracht wird. Bei Temperaturen von 160° bis 220° C erfolgt der Umdruck des Dekors vom Papierträger auf den Polyethylenformkörper, wobei die Thermodiffusionsfarbstoffe zuerst sublimieren und anschließend in den Thermoplast eindiffundieren. Durch dieses Verfahren werden jedoch auf dem Thermoplast lediglich Dekore mit unscharfen Randzonen erzeugt, da die Farbstoffe in das Polyethylen migrieren (ausbluten). Dies führt insbesondere unter UV-Einwirkung zum Verlust der Farbbrillanz bzw. zum gänzlichen Verlust des Dekors. Ferner werden durch das Aufschmelzen der zu bedruckenden Oberfläche so große thermische Spannungen frei, daß das Bedrucken von relativ dünnwandigen, z.B. bahnförmigen Gegenständen wie Skibelägen, ohne zusätzliche Behandlung zur Erzielung eines inneren Spannungsausgleichs nicht möglich ist.From DE-OS 2 731 121 it is known thermoplastic materials like polyethylene to print by the fact that the to be printed Side of the molded polyethylene body under the influence of heat and thereby causing melting with a print carrier such as one paper carrier provided with thermal diffusion dyes, in contact brought. At temperatures of 160 ° to 220 ° C the transfer of the decor from the paper backing to the molded polyethylene, the thermal diffusion dyes sublimate first and then diffuse into the thermoplastic. This procedure, however, only applies to the thermoplastic Decors with blurred edge zones are created because of the dyes migrate into the polyethylene (bleed). This leads in particular under UV exposure to loss of color brilliance or total loss of the decor. Furthermore, by melting the surface to be printed so large thermal Tensions free that the printing of relatively thin-walled, e.g. sheet-like objects such as ski coverings, without additional Treatment for achieving an internal tension balance is not is possible.
So erfolgt im Bereich der Grenzlinie zwischen der aufgeschmolzenen Druckseite und der noch im festen Zustand befindlichen Unterseite ein extremer Spannungsabfall, welcher beim Abkühlen zum Verzug des bedruckten Belags führt. Ferner bewirkt das Aufschmelzen im Fall von vorbehandelten, d.h. geschliffenen und gasbeflammten Skibelagsmaterialien eine Verschlechterung der bereits erzielten mechnischen Eigenschaften wie Zug- und Reißfestigkeit. So takes place in the area of the boundary line between the melted Printing side and the underside, which is still in a solid state an extreme voltage drop, which when cooling to Warping of the printed covering leads. It also causes melting in the case of pretreated, i.e. honed and gas-flamed ski covering materials a deterioration of already achieved mechanical properties such as tensile and tear strength.
Ferner ist aus der EP-A-033 776 ein Verfahren zum Bedrucken von bahnförmigen thermoplastischen Gegenständen wie Skibelägen vorbekannt, bei dem der Belag als heiße Folie mit einem Druckträger vorzugsweise in einem Walzenspalt kontinuierlich in Anlage gebracht wird. Zuvor wurde auf dem Druckträger ein Druckbild aus Thermodiffusionsfarbstoffen erzeugt.Furthermore, EP-A-033 776 describes a method for printing on previously known sheet-shaped thermoplastic objects such as ski coverings, in which the covering is a hot foil with a print carrier preferably continuously in a nip brought. Previously, a print image was made on the print carrier Thermal diffusion dyes produced.
Ebenso beschreibt die CH-PS 542 042 den Umdruck von Thermodiffusionsfarbstoffen auf ein thermoplastisches Substrat in einem Walzenspalt, wobei zum Schutz des Druckmotivs zusätzlich eine Kunststoffolie aufkaschiert wird.CH-PS 542 042 also describes the transfer printing of thermal diffusion dyes on a thermoplastic substrate in one Nip, with an additional to protect the print motif Plastic film is laminated on.
Auch aus der FR-A-2,200793 ist es vorbekannt, gleichzeitig mit dem Bedrucken ein Verstärkungsmaterial aufzukaschieren, sodaß ein mit Thermodiffusionsfarbstoffen versehener Verbund gebildet wird. It is also known from FR-A-2,200793, at the same time as laminate a reinforcing material on the printing so that a composite provided with thermal diffusion dyes becomes.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art anzugeben, das konturenscharfe, verzerrungsfreie Brillantdrucke gewährleistet, bei welchem jedoch keine Verwerfungsprobleme sowie verschlechterte mechanische Eigenschaften nach der Farbübertragung auftreten. Erfindungsgemäß wird daher ein Verfahren zum Bedrucken von thermoplastischen Kunststoffen mit Thermodiffusionsfarbstoffen durch Transferdruck derart vorgeschlagen, daß in einer beheizbaren Presse auf ein diskontinuierlich bewegtes, faserhältiges Trägermaterial durch Umdruck von einem mit Thermodiffusionsfarbstoffen versehenen Papierträger ein Druckbild aus den zuerst sublimier- und dann eindiffundierbaren Farbstoffen erzeugt wird und daß dieses mit Thermodiffusionsfarbstoffen versehene, faserhältige Trägermaterial bei erhöhter Temperatur in einem Kalanderwalzenspalt mit einer Thermoplastschmelze kontinuierlich derart zusammengeführt wird, daß die Thermodiffusionsfarbstoffe in den Thermoplast eindringen und gleichzeitg ein bahnförmiger Verbund, bestehend aus dem faserhältigen Trägermaterial und dem Thermoplast gebildet wird. Durch das erfindungsgemäße Verfahren wird ein konturenscharfer Brillantdruck auf dem Thermoplast erzeugt, welcher bedingt durch die Eindringtiefe der Thermodiffusionsfarbstoffe in den Thermoplast ebenso gegenüber UV-Strahlen farbstabil ist. Ferner weist der bedruckte Thermoplast, bedingt durch das faserhältige Trägermaterial, eine hohe Formstabilität sowie besonders gute mechanische Eigenschaften auf.The present invention is therefore based on the object To specify methods of the type mentioned at the outset, the sharp contours, guarantees distortion-free brilliant prints, at which however, no warp problems as well as worsened mechanical properties occur after ink transfer. According to the invention, therefore, a method for printing on thermoplastics with thermal diffusion dyes proposed by transfer printing such that in a heatable Press on a discontinuously moving, fiber-containing Base material by transfer printing from one with thermal diffusion dyes provided paper carrier a print image from the first sublimable and then diffusible dyes is produced and that this fiber-containing provided with thermal diffusion dyes Backing material at elevated temperature in a calender nip with a thermoplastic melt continuously like this is merged that the thermal diffusion dyes in penetrate the thermoplastic and at the same time a web-shaped Composite, consisting of the fibrous carrier material and the Thermoplastic is formed. By the method according to the invention becomes a sharply contoured brilliant print on the thermoplastic generated, which is due to the depth of penetration of the thermal diffusion dyes in the thermoplastic as well as against UV rays is color stable. Furthermore, the printed thermoplastic due to the fiber-containing carrier material, high dimensional stability as well as particularly good mechanical properties.
Weitere Vorteile der Erfindung ergeben sich daraus, daß als faserhältiges Trägermaterial ein Fasergewebe, -gelege oder vlies eingesetzt wird und die Fasern im Trägermaterial Kunststoffasern und/oder Naturfasern sind, wobei die Kunststoffasern aus Polyester und/oder Polyamid bestehen und die Naturfasern Baumwollfasern sind. Durch diese Maßnahmen ist es gewährleistet, daß bis zu 200°C keine Thermoschrumpfung im faserhältigen Trägermaterial auftritt.Further advantages of the invention result from the fact that fibrous carrier material a fiber fabric, scrim or non-woven is used and the fibers in the carrier material plastic fibers and / or natural fibers, the plastic fibers made of polyester and / or polyamide and the natural fibers are cotton fibers are. These measures ensure that up to at 200 ° C no thermal shrinkage in the fibrous carrier material occurs.

Ein weiter Vorteil der Erfindung besteht darin, daß als Thermoplast Polyethylen oder Polyamid eingesetzt wird.Another advantage of the invention is that as a thermoplastic Polyethylene or polyamide is used.
Ferner betrifft die Erfindung die Verwendung eines mit Thermodiffusionsfarbstoffen bedruckten thermoplastischen Kunststoffes zum Herstellen einer Dekorschicht auf Ski- oder Snowboardbauteilen sowie zum Herstellen einer Dekorschicht auf Kunstoff-Faserverbundwerkstoffen.The invention further relates to the use of a thermal diffusion dye printed thermoplastic for creating a decorative layer on ski or snowboard components as well as for the production of a decorative layer on plastic fiber composite materials.
