Definitions
- the invention relates to a ski base with a dry lubrication effect Basis of polyethylene and at least one additive as well as a Process for making this ski base.
- Gliding a ski on the snow is one special case of friction, namely a so-called tribosystem with the factors of friction, wear and lubrication.
- a tribosystem is formed from four components: from the basic and the counter material as well as the intermediate and surrounding medium.
- the basic material namely the snow, however ice, water and mixtures thereof are also inseparable from the Intermediate medium connected and variable. This follows from the fact that the snow conditions due to an unpredictable number of influencing factors, especially the weather development.
- Another variable factor is the different use of the covering material.
- ski base material This is commonly referred to as ski base material, where it but is also used for snowboards or carving skis.
- ski base material This is commonly referred to as ski base material, where it but is also used for snowboards or carving skis.
- These special ski models are loaded by the driver and Driving style especially in the areas of the ski covering material close to the steel edges shifted.
- This driving style in combination with the partly very grainy and therefore abrasive artificial snow makes it almost impossible, conventional ski covering material made of pure polyethylene to be used because this is not sufficiently high wear resistance having. This causes abrasion damage, which not only the skid, but also the ability to turn the ski or Snowboards on snow until it becomes unusable, in particular for competitive sports.
- a ski covering is therefore the proposed type mentioned, which is characterized is that as an additive boron nitride to an extent of 0.25 to 5.0 % By weight, based on the ski base, is included, and that the ski base other additives, such as fluorine-containing additives and / or carbon black contains.
- boron nitride has a hexagonal crystal structure and is therefore called "white graphite". Because of this crystal structure has boron nitride just like graphite excellent dry lubrication effect.
- the hardness of boron nitride lies in the range of diamond, so that boron nitride is resistant against high abrasion forces.
- boron nitride has one higher resistance to oxidation and thus higher water repellency even over a longer period.
- the ski covering according to the invention shows particularly advantageous properties, if, in addition to boron nitride, a fluorine wax as a further additive is present.
- the invention further relates to a method for producing the Ski covering material according to the invention, which is characterized is that the ski base material based on polyethylene before Press sintered boron nitride in powder form to an extent of 0.25 to 5.0 % By weight and further additives, such as fluorine-containing additives and / or Carbon black can be added.
- another additive is preferably a Fluorine wax added.
- High molecular weight polyethylene with a medium molecular weight of 4 million, for example, 1.5 wt .-% boron nitride in powder form admitted.
- This powdery mixture is made into a round shape filled and cold compressed at a pressure of approx. 100 bar. This The round blank is then heated under pressure for approx. 8 hours and approx. cooled to room temperature for as long. The subsequent peeling process determines the thickness of the ski base.
- This execution of the Invention can be varied, for example, in that the powdery mixture of high molecular weight polyethylene, 1.5% by weight Boron nitride and 5 wt .-% carbon black as a further additive.
- the embodiment of the invention can also be modified in such a way that that the powdery mixture of high molecular weight polyethylene 1.5% by weight boron nitride and 1.5% by weight wax, such as fluorine or paraffin wax, can be added as a further additive.
- wax such as fluorine or paraffin wax
- the possible embodiments of the invention are summarized in the following table, in which the coating composition in% by weight is compared to the flextime in seconds.
- the ski covering according to the invention is not only suitable for production of usual alpine skis, but also for equipping of racing skis, carving skis, snowboards and cross-country skis.
