Definitions

  • the invention relates to a plastic ski base with a particulate that improves the sliding properties Of filler.
  • Polymers are preferred for plastic ski coverings used with a hydrophobic character, such as Polyethylene.
  • tread materials C-modified PE with regard to sliding speed has in the past few years has made them the largest Make up part of the ski base used in ski construction.
  • This Ski coverings contain the filler additive carbon in a relatively large amount. Due to the inherent color of carbon in the soot and graphite modifications these fast-moving ski toppings have a black color on.
  • EP-A-0 538 185 also describes a ski covering with filler, among others with aluminum powder and / or with graphite.
  • the object of the invention is a Specify filler additive to the ski base for the desired Sliding properties in a significantly smaller amount can be added as the usual carbon and with which can be avoided from blackening, so that the Ski surface if desired by adding suitable Colorants can be colored.
  • the plastic ski covering according to the invention, with to whom the task is solved is characterized by that the filler additive is at least one of the following Substances contain: boron, at least one boron compound, at least a nitride.
  • the filler additive can suitably be used as the nitride Contain aluminum nitride.
  • the filler additive boron nitride can be used as the boron compound contain.
  • the Filler additive thus at least one of the following Fabrics: boron, boron nitride, aluminum nitride.
  • the filler additive can also Contain carbon in the form of carbon black and / or graphite.
  • the amount of filler added is Rule 0.2 to 20, preferably 0.5 to 3, parts by weight per 100 parts by weight of plastic.
  • the plastic used can expediently be ultra-high-molecular low-pressure polyethylene with a molecular weight of 4 to 12 ⁇ 10 6 g / mol, which is processed in the press-sintering process, or low-pressure polyethylene with a molecular weight of 200,000 to 600,000 g / mol, which is processed in the extrusion process ,
  • ski base can not only be used in the Press sintering process with subsequent peeling, but also produced, for example, in the extrusion process become.
  • the admixture is essential for the invention of the filler additive mentioned at the beginning.
  • Example 1 96 parts by weight of "Hostalen GUR” 4170 with a molecular weight of 10.5 x 10 6 are processed with 4 parts by weight of aluminum nitride powder (specific surface area 1.2 m 2 / g) as described in Example 1 to form a ski base.
  • the covering has a greyish, homogeneous color.
