Abstract
Description
Die Erfindung betrifft ein kontinuierliches Verfahren zur Herstellung eines mit einem Dekor versehenen bandförmigen Skibelagsmaterials aus ultrahochmolekularem Polyethylen, wobei das Skibelagsmaterial durch Schneckenextrusion, Kolbenstrangpressen oder Sintern mit anschließendem Schälvorgang in einem Dickenbereich von 0,5 bis 1,5 mm hergestellt und anschließend mit Thermodiffusionsfarbstoffen bedruckt wird.The invention relates to a continuous process for Production of a band-shaped ski covering material with a decoration made of ultra high molecular weight polyethylene, the Ski base material through screw extrusion, piston extrusion or sintering with subsequent peeling in a thickness range manufactured from 0.5 to 1.5 mm and then with Thermal diffusion dyes are printed.
Es ist bekannt, Skibauteile u.a. auch Skibelagsmaterialien aus Polyethylen nach dem Siebdruckverfahren mit einem Dekor zu versehen. Dabei wird die Siebdruckfarbe durch ein schabloniertes Gewebe, welches farbdurchlässige sowie farbundurchlässige Stellen je nach gewünschtem Dekor aufweist, auf das bandförmige Skibelagsmaterial aufgedrückt. Anschließend werden die überschüssigen Farbstoffanteile mit einer Rakel abgezogen.It is known that ski components, etc. also ski base materials Polyethylene after the screen printing process with a decor too Mistake. The screen printing ink is stenciled Fabric that has translucent and opaque areas depending on the desired decor, on the ribbon-shaped Ski covering material pressed on. Then the excess Dye portions with a doctor blade.
An einem nach dem Siebdruckverfahren mit einem Dekor versehenen Skibelag wird nun die Anforderung gestellt, daß die Siebdruckfarben auch auf der Rückseite des Belagsmaterials, welches der Schneeoberfläche und damit auch dem Betrachter zugewandt ist, gut sichtbar erscheinen, da an der bedruckten Seite die weitere Verklebung mit den übrigen Skibauteilen erfolgt. Es hat sich jedoch gezeigt, daß die Farbintensität des Dekors negativ durch das milchig-weiße Aussehen des Polyethylens beeinflußt wird, sodaß das Dekor für den Betrachter schlecht sichtbar ist.On a decor with a screen printing process Ski covering is now the requirement that the screen printing inks also on the back of the covering material, which the Snow surface and thus facing the viewer, appear well visible because the other side is printed Glued to the other ski components. It has however, showed that the color intensity of the decor is negatively affected by the milky-white appearance of the polyethylene is influenced, so that the decor is difficult for the viewer to see.
Aus der AT-PS 362 691 ist es bekannt, eine Skioberflächenschicht aus Kunststoff nach dem Transferdruckverfahren mit einem Dekor zu versehen. Dabei werden die Thermodiffusionsfarbstoffe auf einem Zwischenträger wie Papier aufgebracht und mit dem Kunststoff heiß verpreßt, wobei diese in die Gasphase oder Schmelze übergehen und in den Kunststoff eindringen. Dieses Verfahren wäre auch zur Dekorierung von Skibelägen denkbar.From AT-PS 362 691 it is known to have a ski surface layer made of plastic using the transfer printing process with a Decor. Thereby the thermal diffusion dyes applied on an intermediate support like paper and with the Plastic hot pressed, this in the gas phase or Pass over the melt and penetrate the plastic. This Processes would also be conceivable for decorating ski toppings.
Ferner ist aus der DE-OS 30 04 518 ein Verfahren zum Bedrucken von thermoplastischen Kunststoffen wie Skibelägen mit Thermodiffusionsfarbstoffen durch Transferdruck geoffenbart. Furthermore, DE-OS 30 04 518 describes a method for printing of thermoplastic materials such as ski coverings Thermal diffusion dyes revealed by transfer printing.
Dabei erfolgt die Übertragung der Transferdruckfarben von dem Druckträger auf die thermoplastische Folie durch "In-Anlage-Bringen" der Folie an den Druckträger innerhalb eines Zweistufenprozesses. Die Druckbildübertragung erfolgt gemäß Fig. 1 in einem Kalanderwalzenspalt, durch welchen die zu bedruckende Folie in Form einer Schmelzfahne geführt und mit dem Hilfsdruckträger 3 in Kontakt gebracht wird. Durch den aufgebrachten Druck und die erhöhte Temperatur im Kalanderwalzenspalt erfolgt die Übertragung des Druckmotives solange, bis der Hilfsdruckträger druckbilderschöpft ist.The transfer printing inks are transferred from the Print carrier on the thermoplastic film by "bringing it into contact" the film to the print medium within a Two-step process. The print image is transferred according to Fig. 1 in a calender nip through which the to be printed Guided foil in the form of a melting plume and with the Auxiliary printing medium 3 is brought into contact. By the applied pressure and the increased temperature in the calender nip the print motif is transferred until the auxiliary print carrier is exhausted.
Diese Verfahren sind jedoch insoferne aufwendig, da an den Zwischenträger, das heißt an die mit den Thermodiffusionsfarbstoffen bedruckten Papiere hohe Anforderungen wie hohe Dimensionsstabilität, gute Bedruckbarkeitseigenschaften sowie Oberflächeneigenschaften, welche das Eindringen der Druckfarbe weitgehend verhindern, sodaß eine hohe Ausbeute an Farbstoff auf den zu bedruckenden Kunststoff gewährleistet ist, gestellt werden. Ferner müssen die Zwischenträger in zusätzlichen Verfahrensschritten auf den zu bedruckenden Kunststoff wie den Skibelag aufgebracht und nach dem Bedrucken wieder abgelöst werden. Nach ihrer Verwendung müssen die Zwischenträger entsorgt werden, da sie in keinem weiteren Verfahrensschritt eingesetzt werden können.However, these processes are expensive because of the Intermediate carrier, that is to say those with the thermal diffusion dyes printed papers high requirements such as high Dimensional stability, good printability properties as well Surface properties that prevent the ink from penetrating largely prevent, so that a high yield of dye the plastic to be printed is guaranteed will. Furthermore, the intermediate carrier in additional Process steps on the plastic to be printed such as the Ski covering applied and detached again after printing will. After their use, the intermediate supports must be disposed of be used since they are not used in any further process step can be.
Aus der WO-A1 81/03462 ist ein Verfahren zum Bedrucken von
thermoplastischen Kunststoffen wie beispielsweise Skibelagsmaterialien
nach dem Thermodiffusionsdruckverfahren
mit den Merkmalen des Oberbegriffs des Anspruchs 1
vorbekannt, in
welchem keinerlei Druckhilfsträger eingesetzt werden. Dabei wird
der thermoplastische Kunststoff durch einen Kalanderwalzenspalt,
welcher durch eine Farbträgerwalze und eine Gegenwalze
ausgebildet ist, geführt, und in diesem durch Übertragung des
Druckmotives von der Farbträgerwalze bedruckt. Anschließend
passiert der bedruckte thermoplastische Kunststoff eine
Tempereinrichtung, um eine gesteuerte Abnahme der Temperatur
gewährleisten zu können. Dieses Verfahren ist nun hinsichtlich
der Variation der Farbstoffzusammensetzung limitiert, da bei der
Ausbildung von mehrfärbigen Dekoren eine relativ aufwendige
Verfahrensführung durch Maßnahme mehrerer Farbwalzen notwendig
wird.WO-A1 81/03462 describes a method for printing on
thermoplastic materials such as ski base materials
according to the thermal diffusion printing process
with the features of the preamble of
Neben den Anforderungen an das Dekor sowie dessen Herstellung auf dem Skibelag muß dieser die notwendigen physikalischen Eigenschaften wie eine hohe Abriebfestigkeit sowie eine gute Wachsaufnahme aufweisen.In addition to the requirements for the decor and its manufacture on the ski base this must have the necessary physical Properties such as high abrasion resistance as well as good Have wax absorption.
Aus der WO-A1-93/05853 ist es bekannt, die Abriebfestigkeit des Skibelagsmaterials durch die Molmasse des Polyethylens zu bestimmen, sodaß zwangsläufig ultrahochmolekulares Polyethylen zum Einsatz kommt.From WO-A1-93 / 05853 it is known that the abrasion resistance of the Ski base material due to the molecular weight of the polyethylene determine, so that inevitably ultra high molecular weight polyethylene is used.
Ebenso wird gemäß der EP-A1-319435 ultrahochmolekulares Polyethylen eingesetzt, welches vor der Schmelzextrusion zusätzlich in einem Mischer vorbehandelt wird, sodaß das Gleitverhalten des endgefertigten Skibelags verbessert wird.Likewise, according to EP-A1-319435 ultra high molecular weight polyethylene used, which additionally before melt extrusion is pretreated in a mixer so that the sliding behavior of the finished ski base is improved.
Da nunmehr die Wachsaufnahme von der Dichte des UHWPE und damit vom kristallinen Anteil im ultrahochmolekularen Polyethylen abhängt, wird dieser durch gezielte Umkristallisation auf die größtmögliche Wachsaufnahme gemäß dem Verfahren der WO-A1-93/05853 eingestellt.Since now the wax absorption from the density of the UHWPE and thus depends on the crystalline content in the ultra high molecular weight polyethylene, is this through targeted recrystallization on the maximum possible wax absorption according to the method of WO-A1-93 / 05853 set.
Aufgabe der Erfindung ist es daher, ein Skibelagsmaterial aus ultrahochmolekularem Polyethylen in einem leicht durchführbaren Verfahren mit einem farbintensiven Dekor zu versehen, wobei das mit dem Dekor versehene Skibelagsmaterial zusätzlich eine hohe Wachsaufnahme sowie Abriebfestigkeit aufweisen soll.The object of the invention is therefore to make a ski base material ultra high molecular weight polyethylene in an easy to carry out Process to provide a color-intensive decor, the with the decor provided ski covering material also a high Wax absorption and abrasion resistance should have.

Weitere Vorteile der Erfindung bestehen darin, daß das mit Thermodiffusionsfarbstoffen bedruckte, bandförmige Skibelagsmaterial ein nach einem Siebdruckverfahren, Flexodruckverfahren oder Tiefdruckverfahren bedrucktes Skibelagsmaterial ist.Further advantages of the invention are that with thermal diffusion dyes printed, band-shaped ski covering material one after a screen printing process, flexographic printing process or Rotogravure is printed ski base material.

Das erfindungsgemäße Verfahren wird anhand folgender allgemeiner Arbeitsvorschrift erläutert:The method according to the invention is more general on the basis of the following Working instructions explained:
Von einer Vorratsrolle 3 wird das mit Thermodiffusionsfarbstoffen
versehene Skibelagsmaterial 4, das gegebenenfalls
durch an sich bekannte Verfahren wie Schneckenextrusion, Kolbenstrangpressen
oder Preßsintern hergestellt und anschließend nach
dem Sieb- oder Flexo- oder Tiefdruckverfahren mit den Thermodiffusionsfarben
bedruckt wurde, abgezogen, über die Umlenkrolle 5
umgelenkt und mit der Geschwindigkeit v [m/min] der Heizzone
(1), die beispielsweise mit IR-Heizelementen ausgestattet sein
kann, zugeführt. In der Heizzone mit der Länge l(H) schmilzt das
ultrahochmolekulare Polyethylen bei einer Temperatur von über
140°C. Von der Verweilzeit des Skibelagsmaterials, die proportional
zur Länge l(H) ist, hängt es nun ab, inwieweit das
Kristallgefüge zerfällt. Von der Verweilzeit l(H) hängt es auch
ab, inwieweit die Farbpigmente der Thermodiffusionsfarbstoffe
sublimieren und/oder schmelzen und in der Folge in das geschmolzene
Skibelagsmaterial diffundieren. Dieser Vorgang erfolgt
ohne Zuhilfenahme eines Zwischenträgers für die Thermodiffusionsfarbstoffe
wie es beispielsweise aus der AT-PS 362 691
vorbekannt ist. Anschließend passiert dieses geschmolzene Skibelagsmaterial
die Kühlzone, die aus zwei Kalibrierplatten (2, 2')
besteht. Diese haben die Aufgabe, dem geschmolzenen Skibelagsmaterial
eine Form zu geben und diese gleichzeitig zu kühlen
sowie die Thermodiffusionsfarbstoffe im Skibelagsmaterial zu
fixieren. Während des Kühlens kristallisiert das ultrahochmolekulare
Polyethylen aus; auch dieser Vorgang hängt von der
Verweilzeit des Skibelagsmaterials ab, die proportional zur
Länge der Kühlzone l(K) ist. Anschließend passiert das abgekühlte
Skibelagsmaterial das Abzugsrollenpaar 6 und wird danach auf
die Depotrolle 7 aufgerollt.From a supply roll 3 that is with thermal diffusion dyes
