DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a lubricating composition on the basis of hydrocarbon waxes (ski-waxes), absorbed on a flexible support of pocket format and particularly suitable to improve the characteristics of slipperiness and of water-repellency of the sliding surfaces to the sliding surfaces of skis, sledges, sliding devices and the like.
The use of ski-waxes on skis, sliding devices, and the like, to the purpose of increasing their slipperiness on snow, preventing snow from adhering on said soles, is known.
The ski-waxes presently more widely used for the present sliding surfaces of polymeric, and in particular polyethylenic, nature, are usually blends of paraffins and microcrystalline hydrocarbon waxes, variously formulated as a function of the types of snow, and of the environmental conditions under which it is used. In particular, for ski bases, and the like, linear or branched hydrocarbons having from about 12 to about 50 carbon atoms are preferably used, in as much as such hydrocarbons, thanks to their structure, are easily absorbed and/or adsorbed by the surface of the polyethylene base, in particular in its crystallite-free areas.
The application techniques for these ski-waxes generally comprise: either the high-temperature application (molten ski-wax), or the application at ambient temperature, by the smearing of ski-waxes in paste form, or by the spray application, by using dispersed ski-waxes. But the techniques of the prior art show, from a practical viewpoint, considerable drawbacks, above all as regards their poor practicalness of accomplishment by the amateur users, or by the users not provided with the necessary tools; that, because the melt techniques require the availability of equipment, and laborious operations; and the ambient-temperature techniques create encumbrances due to need of carrying cans, tubes, and the like, while the most customary conditions of application by the skier-users occur on the ski slopes, when the slipperiness of skis becomes insufficient because of the adherence of snow onto the ski soles.
Thus, a purpose of the present invention is to provide the skier-users, and the like, with a ski-waxing composition, suitably absorbed on a flexible support, of reduced dimensions, and tightly sealed inside of water-proof package, easily carried by the user with no hindrance with respect to ski-handling and the movements of the user, able to constitute an article of pocket format very handy and which is practical to be used.
Another purpose of the invention is to provide a pocket ski-waxing composition, the composition of which is such as to display optimum slipperiness characteristics, a low toxicity and a high degree of penetration into the polyethylenic ski base, said ski-waxing composition being supported by a flexible support and constituting a useful and practical article for the manual application of the ski-waxing blend onto the ski base, with the advantage that the same article can be thrown away soon after use.
These and still other purposes, which shall appear more clearly from the following detailed disclosure, are advantageously achieved by a lubricating composition on the basis of waxy substances, supported on means able to allow it to be applied, manually and at room temperature, to the ski base, to the sliding surfaces of sledges, sliding devices and the like, the composition of which is constituted, according to the present invention, by a blend comprising at least one hydrocarbon wax (ski-wax) and at least one suitable solvent for it, said composition being absorbed by impregnation on a flexible and porous support of small dimensions, able to transfer, by rubbing, said composition onto said sliding surfaces and the like. More particularly, said solvent comprises a hydrogenated naphthalene, preferably decahydronaphthalene (decalin), and said flexible support is selected from such fibrous materials as paper, fabrics and felts on the basis of natural, synthetic and artificial fibres, shaped as a serviette, small napkin, pad, sponge, stick, or the like, of
