Description

Dr. Walter K o f 1 e r, Mittenwald, Wasserwies 6 Schutzbelag für Holzteile, insbesondere Ski Es ist bekannt, als gleitsohle für Skier Auflagen aus Polyäthylen zu verwenden. Diese Polyäthylenauflagen werden z, B, nach dem in der österreichischen Patentschrift 178 576 beschriebenen Verfahren auf die Skier montiert. Der Nachteil dieser Polyäthylenschichten ist der, dass das Polyäthylen infolge Sonneneinstrahlung, insbesondere aufgrund des Ultraviolettanteils im Sonnenlicht, im Laufe der Zeit mehr oder weniger oberflächlich oxydiert. Diese Oxydationsschichten sind jedoch bei weitem nicht so wasserabweisend wie Oberflächen aus reinem Polyäthylen und weisen daher auch eine viel geringere gleitfähigkeit auf Schnee auf. Zur Vermeidung dieser bekannten Oxydationsvorgänge im Sonnenlicht wird dem Polyäthylen für Gegenstände, die im Freien lagern (Kabel usw.), eine verhãltnismässig grosse Menge Russ zugesetzt. Dieser Russzusatz verhindert infolge Absorption ein tieferes Eindringen der Lichtstrahlen, so dass nur die allerobersten Schichten oxydieren können. Diese oberflächlichen Oxydationsschichten würden beim Fahren mit den. Skiern wahrscheinlich bald abgefahren werden ; jedoch bedeutet der Russzusatz selbst eine Verminderung der Gleitfähigkeit. Russ ist im Gegensatz zu Polyäthylen nicht wasserabstossend, so dass die Russzusätze schon von sich aus eine geringe Wasseranlagerung begünstigen, die-ie oben ermähntdie Gleitfähigkeit vermindert.Dr. Walter K o f 1 e r, Mittenwald, Wasserwies 6 Protective covering for wooden parts, in particular skis It is known as a sliding sole for ski pads made of polyethylene to use. These polyethylene pads are z, B, after the Austrian Patent specification 178 576 described method mounted on the skis. The disadvantage of these polyethylene layers is that the polyethylene as a result of solar radiation, especially due to the amount of ultraviolet in sunlight, over time more or less superficially oxidized. However, these oxidation layers are nowhere near as water-repellent as surfaces made of pure polyethylene and white therefore a much lower sliding ability on snow. To avoid this known oxidation processes in sunlight, polyethylene is used for objects, that are stored outdoors (cables, etc.), a relatively large amount of soot added. This addition of soot prevents the light rays from penetrating deeper due to absorption, so that only the very top layers can oxidize. These superficial Oxidation layers would occur when driving with the. Probably skiing soon be driven off; however, the addition of soot itself means a reduction in the Sliding ability. In contrast to polyethylene, soot is not water-repellent, so that the soot additives by themselves favor a low water accumulation, die -ie above admonishes the lubricity diminishes.

Der neuerungsgemäss aus Kunststoff, insbesondere aus : poläthylen, bestehende Schutzbelag für Holzteilen insbesondere für Ski, ist demgegenüber dadurch gekennzeichnet, dass dem Kunststoff zur Verminderung seiner Oxydation durch UV-Licht fluoreszierende oder phosphoreszierende Stoffe beigemischt sind. Auch eine Mischung verschiedener fluoreszierender Stoffe kann verwendet werden.The new one made of plastic, in particular made of: polyethylene, Existing protective covering for wooden parts, in particular for skis, is by contrast characterized in that the plastic is used to reduce its oxidation by UV light fluorescent or phosphorescent substances are mixed in. Also a mixture various fluorescent materials can be used.

Die oxydationsbemmende Wirkung der neuerungsgemässen. Zusätze entsteht dadurch, dass insbesondere die UV-Strahlung durch die fluoreszierenden Stoffe zunächst absorbiert aber dann entweder unverändert oder nach Umwandlung in violettes oder blaues Licht entweder-bei floureszierenden Stoffen-sofort oder-bei phosphoreszierenden Stoffen-nach einiger Zeit wieder emittiert wird. Es wird also allenfalls die Differenzenergie zwischen dem UV-Licht und dem Violett-oder Blaulicht im Kunststoff absorbier. Da aber die Oxydation fast ausschliesslich durch die UV-Strahlung ausgelöst wird, reicht die Differenzenergie bei weitem nicht aus, um eine Oxydation hervorzurufen.The antioxidant effect of the innovation. Additions arise in that in particular the UV radiation through the fluorescent substances initially but then absorbs either unchanged or after conversion to purple or Blue light either - immediately with fluorescent materials - or - with phosphorescent materials Substances-is emitted again after some time. So at most it will be the differential energy absorbing between the UV light and the violet or blue light in the plastic. There but the oxidation is triggered almost exclusively by the UV radiation, is sufficient the difference energy is by no means sufficient to cause oxidation.

Gegenüber einem Zusatz von Russ ergeben sich somit zwei Vorteile : Einerseits fällt die die Gleitfähigkeit vermindernde Wirkung des Russes fort und andererseits wird die energiereiche UV-Strahlung nicht bleibend absorbiert sondern wieder emittiert bzw. umgewandelt und dann wieder emittierte Kunststoffgleitsohlen für Skier mit Zusätzen von fluoreszierenden Stoffen verlieren also auch bei starker Bestrahlung durch UV-Licbt nicht die optimalen Gleiteigenschaften des reinen Kunststoffs, insbesondere des reinen Polyäthylens auf Schnee.There are two advantages over the addition of carbon black: On the one hand, the one that reduces the lubricity falls Effect of Russes gone and on the other hand, the high-energy UV radiation is not permanent absorbed but emitted again or converted and then emitted again Lose plastic sliding soles for skis with additions of fluorescent substances So even with strong irradiation by UV-Licbt, the optimal sliding properties are not achieved of pure plastic, especially pure polyethylene on snow.

In der Figur ist ein Ausführungsbeispiel der Neuerung dargestellt. Es zeigt einen mit einem neuerungsgemässen Schutzbelag versehenen Ski.In the figure, an embodiment of the innovation is shown. It shows a ski provided with a protective coating in accordance with the innovation.

Auf dem Holzteil 1 des Skis ist eine Gewebeschicht 2 aufgeleimt, auf deren anderer Seite sich eine aufgepresste Schicht 3 aus Polyäthylen befindet. Die Schicht 3 ist mit durch Punkte dargestellten fluoreszierenden Stoffen 5 versetzt.A fabric layer 2 is glued onto the wooden part 1 of the ski the other side of which is a pressed-on layer 3 made of polyethylene. the Layer 3 is mixed with fluorescent substances 5 represented by dots.

Seitlich ist die Polyäthylenschicht 5 durch Stahlkanten 4 begrenzt.The side of the polyethylene layer 5 is bounded by steel edges 4.
