Die Erfindung betrifft ein Verfahren zum Herstellen eines Laufflächenbauteils für Skier, welcher einen Laufflächenbelag anfweist, der durch Extrusion eines band- oder plattenförmigen Materials, das zumindest überwiegend aus Polyethylen besteht, erzeugt wird, wobei an eine Oberflächenseite dieses band- oder plattenförmigen Materials - noch vor dessen Abkühlung - ein flächiges Material, welches gegebenenfalls aus einer Polyethylen-5 folie besteht, anlaminiert wird. Sie betrifft ferner einen Ski, der einen nach dem erfindungsgemäßen Verfahren hergestellten Laufflächenbauteil enthältThe invention relates to a method for producing a tread component for skis, which exhibits a tread covering, which is produced by extrusion of a strip or plate-shaped material, which consists at least predominantly of polyethylene, with a surface side of this strip or plate-shaped material - still before its cooling - a flat material, which may consist of a polyethylene-5 film, is laminated on. It also relates to a ski which contains a tread component produced by the method according to the invention
Diese Laminate können, wie aus der DE-OS 1704 8S7 hervorgeht, aus im Schmelzzustand kompoundiertem Polyethylen hoho* Dichte, welches zu einer Folie geformt und anschließend auf ein Grundmatmal aufgebracht wird, hergestellt werden. Derartige Polyethylenlaminate werden in der Skiindustrie für Laufsohlen verwendet, da 10 Polyethylen einen apolaren Charakter besitzt der die guten Gleiteigenschaften auf dem Schnee, Wachsaufhahme- fähigkeit und hohe Verschleißfestigkeit (beim endgefertigten Ski) bewirktAs is apparent from DE-OS 1704 8S7, these laminates can be produced from high-density polyethylene compounded in the melt state, which is formed into a film and then applied to a basic mat. Polyethylene laminates of this type are used in the ski industry for outsoles, since 10 polyethylene has an apolar character which results in good sliding properties on the snow, wax absorption ability and high wear resistance (in the finished ski)
Gemäß der CH-PS SS9.SS6 werden zwei Polyethylenplatten, die auf einer Extrusionsanlage für Niederdruckpolyethylen hergestellt wurden, zu einem Laminat für Skilaufsohlen zusammengeschweißt.According to CH-PS SS9.SS6, two polyethylene plates, which were produced on an extrusion system for low-pressure polyethylene, are welded together to form a laminate for ski soles.
Ebenso beschreibt die CH-PS ein Verfahren zur Herstellung eines Ski-Laufflächenbelages, bei dem zwei 15 extrudierte Polyethylenfolien miteinander verschweißt werden.The CH-PS also describes a process for producing a ski tread surface, in which two 15 extruded polyethylene foils are welded together.
Weiters haben sich auch Laufflächenbeläge aus einem hochmolekularen Polyethylen sehr gut bewährt, wobei man zu ihr» Herstellung das Polyethylenpulver zu dichten Blöcken heiß sintert, aus denen dann die Lauffiächen-beläge durch einen Schälvorgang gewonnen werden. Diese Art der Herstellung hat nun aber als semikontinuierliches Verfahren einige Nachteile, insbesondere den einer beträchtlichen Abfallmenge an gesintertem Material, das 20 nur schwer wiederverwertet werden kann. Die Herstellung von Laufflächenbauteilen, welche die so hergestellten Laufflächenbeläge enthalten, erfolgt auf konventionelle Weise durch ein Miteinander-Verkleben der einzelnen Bauteilkomponenten.Furthermore, tread coverings made of a high molecular weight polyethylene have proven very effective, whereby for their manufacture the polyethylene powder is hot sintered into dense blocks, from which the tread coverings are then obtained by a peeling process. However, this type of production has some disadvantages as a semi-continuous process, in particular that of a considerable amount of waste of sintered material, which is difficult to recycle. The production of tread components which contain the tread coverings produced in this way takes place in a conventional manner by gluing the individual component components together.
Der Erfindung liegt nun zunächst die Aufgabe zugrunde, ein kontinuierliches Verfahren zum Herstellen eines Laufflächenbauteils anzugeben. Die der Erfindung zugrunde liegende Aufgabe wird in dem erfindungsgemäßen 25 Verfahren gelöst, das dadurch gekennzeichnet ist, daß das eingesetzte Polyethylen des band- oder plattenförmigenThe invention is first of all based on the object of specifying a continuous method for producing a tread component. The object on which the invention is based is achieved in the method according to the invention, which is characterized in that the polyethylene used is in the form of a strip or plate
Materials eine mittlere Molmasse (Gewichtsmittel) im Bereich zwischen 5.10^ und 8.10^ aufweist und daß das anlaminierte flächige Material eine Folie ist, die zumindest überwiegend aus Polyethylen mit einer mittlerenMaterials has an average molecular weight (weight average) in the range between 5.10 ^ and 8.10 ^ and that the laminated flat material is a film that is at least predominantly made of polyethylene with a medium
Molmasse (Gewichtsmittel) kleiner als 5.10^ besteht, oder ein Faservlies, vorzugsweise ein Polyestervlies, ist.Molar mass (weight average) is less than 5.10 ^, or is a nonwoven fabric, preferably a polyester nonwoven.
Mit dem erfindungsgemäßen Verfahren kann ein Produkt hoher Qualität mit geringem verfahrenstechnischen 30 Aufwand hergestellt werden.With the method according to the invention, a product of high quality can be produced with little procedural effort.
Nach einer vorteilhaften Ausgestaltung des erfindungsgemäßen Verfahrens wird die zumindest überwiegend aus Polyethylen bestehende zu extrudierende Masse mit niedermolekularen Zusätzen wie Ölen, Paraffinen, Gleitmitteln, Hydrophobierungsmitteln und dgl. gemischt zur Extrusion eingesetztAccording to an advantageous embodiment of the method according to the invention, the mass to be extruded, which consists at least predominantly of polyethylene, is used mixed with low molecular weight additives such as oils, paraffins, lubricants, water repellents and the like for extrusion
Diese Zusätze bewirken die bessere Gleitfähigkeit des endgefertigten Skis auf dem Schnee, da insbesondere die 35 hydrophobierenden Gleitmittel die Festköipeneibung Ski - Schnee vermindern.These additives improve the smoothness of the finished ski on the snow, since the 35 hydrophobizing lubricants in particular reduce the firmness of the ski and snow.
Gemäß einer anderen vorteilhaften Ausgestaltung der Erfindung ist das erfindungsgemäße Verfahren dadurch gekennzeichnet daß das anzulaminierende flächige Material an der Seite, anderes mit dem Polyethylen-Laufflächenmaterial verbunden werden soll, mit einer dekorativen Schicht vorzugsweise einem Aufdruck versehen ist.According to another advantageous embodiment of the invention, the method according to the invention is characterized in that the sheet material to be laminated on the side, another to be connected to the polyethylene tread material, is preferably provided with a decorative layer.
Das Verfahren gewährleistet damit unter geringem apparativen Aufwand optische Gestaltungsvarianten, wobei 40 das Dekor des durchscheinenden Laufflächenbelagsmaterials zu erkennen istThe method thus ensures optical design variants with little outlay on equipment, the decor of the translucent tread material being recognizable
Gegenstand der Erfindung ist schließlich ein Ski, der einen durch das erfindungsgemäße Verfahren hergestellten Laufflächenbauteil enthältFinally, the invention relates to a ski which contains a tread component produced by the method according to the invention
Der Einsatz des »findungsgemäßen Laufflächenbauteils bringt dem Skierzeuger ein hohes Maß an rationeller Fertigung des Skis durch den Wegfall sämtlicher nachfolgend» mechanischer Bearbeitungsschritte. Trotz des 45 apparativ wenig aufwendigen Verfahrens entsteht ein Ski mit guten Gleiteigenschaften auf dem Schnee und hoher V»schleißfestigkeitThe use of the tread component according to the invention gives the ski manufacturer a high degree of rational manufacture of the ski by eliminating all subsequent mechanical processing steps. Despite the method, which is not very expensive in terms of equipment, a ski is produced with good sliding properties on the snow and high wear resistance
Die Erfindung wird nachstehend anhand der Figuren 1 und 2 sowie Beispielen näher erläutertThe invention is explained in more detail below with reference to FIGS. 1 and 2 and examples
Fig. 1 zeigt nun in ein» schematischen Darstellung eine Vorrichtung zur Herstellung eines Laufflächenbau-50 teil-Materials als Endlosstrang.Fig. 1 shows a »schematic representation of a device for producing a tread construction 50-part material as an endless strand.
Fig. 2 zeigt dieses Laufflächenbauteil-Material im LängsschnittFig. 2 shows this tread component material in longitudinal section
Zur H»stellung eines Skilaufflächenbauteils wird erfindungsgemäß ein Laufflächenbelag (6) auf der Basis eines hochmolekularen Polyethylens mit einer mittleren Molmasse (Gewichtsmittel) von beispielsweise 5.10^ 55 erzeugt Für die Verarbeitung von Polyethylen so hoher Molmasse bedient man sich vorzugsweise eines sogenannten Ram-Extrusionsverfahrens. Eine Vorrichtung zur Durchführung dieses V»fahrens ist in Fig. 1 skizziert wobei der Ramextruder durch die Düse (1) angedeutet ist. Weiters besteht die Vorrichtung aus einem Dreiwalzenkalander mit den Kalanderwalzen (2), (3) und (4) sowie ein» Vorratsrolle (5) für das anzulaminierende Material. Dieses Verfahren wurde in den letzten Jahren zur Verarbeitung von ultrahochmolekularen Thermo-60 plasten entwickelt, die wegen ihrer hohen Molmase nicht mehr plastifizierbar sind und sich daher durch eine übliche Schmelzextrusion nicht mehr v»arbeiten lassen. Bei diesem Ram-Extrusionsverfahren wird der zu extru- -2-To produce a ski tread component, a tread covering (6) based on a high molecular weight polyethylene with an average molecular weight (weight average) of, for example, 5.10 ^ 55 is produced for the processing of polyethylene of such high molecular weight, preferably using a so-called ram extrusion process. A device for carrying out this process is outlined in FIG. 1, the ram extruder being indicated by the nozzle (1). Furthermore, the device consists of a three-roll calender with the calender rolls (2), (3) and (4) and a »supply roll (5) for the material to be laminated. This method has been developed in recent years for processing ultra-high molecular thermoplastics, which are no longer plasticizable due to their high molar mass and can therefore no longer be processed by conventional melt extrusion. With this ram extrusion process, the
