Description
Oppfinnelsen angår en sportsartikkel for å gli eller løpe The invention relates to a sports article for sliding or running
på sne eller is, spesielt ski, med et sålelignende plastbelegg, on snow or ice, especially skis, with a sole-like plastic coating,
og dessuten en fremgangsmåte ved fremstilling av sportsartikkelen. and furthermore a method of manufacturing the sports article.
Det har lenge vært kjent å anvende forskjellige plaster som belegg for utforski og langrennsski. Plastene påklebes som folier eller påfør.es i flytende form, eventuelt oppløst i organiske opp-løsningsmidler eller i oppvarmet og forflyktiget form, og, om nød-vendig, herdes kjemisk. It has long been known to use different plasters as coatings for exploring and cross-country skiing. The plastics are glued on as foils or applied in liquid form, optionally dissolved in organic solvents or in heated and volatilized form, and, if necessary, chemically cured.
Disse plastbeleggs kjemiske sammensetning er forskjellig. Polyethylen har gitt gode resultater." på grunn av sine gode glideegenskaper for forskjellige snetyper, sin gode mekaniske fasthet og sin forholdsvis enkle bearbeidbarhet. Foruten polyethylen for-søkes det med eller anvendes det imidlertid også belegg på f.eks. epoxydharpiksbasis, polyamidbasis og fenolharpiksbasis. Det er felles for alle disse belegg at de gir en kompakt, praktisk feil-fri overflatestruktur slik at de gir en glatt, lukket slitesåle. Ved å slipe belegget kan det oppnås en viss overflateruhet som forbedrer vedheftningen av skismurning. The chemical composition of these plastic coatings is different. Polyethylene has given good results because of its good sliding properties for different types of snow, its good mechanical strength and its relatively easy workability. Besides polyethylene, however, coatings based on e.g. epoxy resin, polyamide and phenolic resin are also tried or used . Common to all these coatings is that they provide a compact, practically defect-free surface structure so that they provide a smooth, closed tread sole. By grinding the coating, a certain surface roughness can be achieved which improves the adhesion of ski masonry.
Mens de ovenfor nevnte belegg har gitt gode resultater ved alpine utforrenn, later de meget tilbake å ønske for langrenn. While the above-mentioned coatings have given good results for alpine downhill skiing, they leave much to be desired for cross-country skiing.
På grunn av beleggenes kompakthet og fasthet går en del av skiens elastisitet tapt, og den blir tung. Skismurning hefter riktignok godt til polyethylenbelegg, men spesielt når sneen er hård, slites smurninglaget forholdsvis hurtig av. Due to the compactness and firmness of the coatings, part of the ski's elasticity is lost, and it becomes heavy. Ski lubrication adheres well to polyethylene coatings, but especially when the snow is hard, the lubrication layer wears off relatively quickly.
På grunn av disse mangler er det blitt gjort forsøk på å prege slitesålen slik at det skal bli lettere å gå oppover bakke på skiene. Således er i DT-OS 1578922 innpreging av et fiske-sk jellmøns ter beskrevet. Ved ..en annen fremgangsmåte freses langs-gående spor i skibelegget, og filtstrimler klebes inn i sporene for å hindre skiene fra å glippe. Because of these shortcomings, attempts have been made to emboss the sole so that it will be easier to go uphill on the skis. Thus, in DT-OS 1578922 the embossing of a fish-skeleton pattern is described. In another method, longitudinal grooves are milled in the ski coating, and strips of felt are glued into the grooves to prevent the skis from slipping.
De nevnte fremgangsmåter er imidlertid beheftet med den ulempe at de gjør skiene mindre bakglatte bare på bekostning av skienes glideevne og at de ikke muliggjør en individuell tilpasning til de forskjellige snetyper ved valg og påføring av skismurning. However, the aforementioned methods are fraught with the disadvantage that they make the skis less slippery at the back only at the expense of the skis' gliding ability and that they do not enable an individual adaptation to the different types of snow when choosing and applying ski binding.
Det har nu vist seg at de nevnte ulemper kan overvinnes hvis det. istedenfor et belegg med lukket overflate anvendes et belegg med åpen overflate som matematisk betraktet kan betegnes som "fler-sammenhengende" og som har inneslutninger som dannes ved hjelp av tverrsnitt gjennom hulrom som gir en ujevnhet på overflaten. It has now been shown that the aforementioned disadvantages can be overcome if instead of a coating with a closed surface, a coating with an open surface is used which mathematically can be described as "multi-cohesive" and which has inclusions which are formed by means of cross-sections through cavities which give an unevenness on the surface.
Slike overflater kan fremstilles f.eks. ved at et råbelegg Such surfaces can be produced e.g. in that a raw coating
på. polyurethanbasis herdes ved forhøyet fuktighet, hvorved dannes en blæreholdig struktur. Dersom slike råbelegg slipes, fås en grov-til finporet beleggoverflate. on. polyurethane base hardens at elevated humidity, whereby a blister-like structure is formed. If such raw coatings are sanded, a coarse to finely porous coating surface is obtained.
De beste resultater erholdes imidlertid med skibelegg som fremstilles ved sintring av finkornige plastpartikler. På grunn av sintringen dannes en sammenhengende kapillarstruktur i belegget, However, the best results are obtained with ski coatings that are produced by sintering fine-grained plastic particles. Due to the sintering, a continuous capillary structure is formed in the coating,
og ved sliping eller oppskjæring fås en åpen overflate. I mot-setning til et skummet materiale med åpne celler, er ryggene mellom porene bredere slik at det fås en høyere mekanisk fasthet samtidig med en god elastisitet. and by grinding or cutting an open surface is obtained. In contrast to a foamed material with open cells, the ridges between the pores are wider so that a higher mechanical firmness is obtained at the same time as good elasticity.
I de dannede porer kan skismurningen sitte bedre fast, og den slites ikke så fort av ved gliding mot sne. På grunn - av skismurningen som blir tilbake i kapillarrørene og på grunn av belegg-overflåtenes fine struktur er det blitt oppnådd betraktelig bedre glideegenskaper enn med glatte belegg. In the pores formed, the ski lining can stick better, and it does not wear off as quickly when sliding against snow. Due to - the ski wall that remains in the capillary tubes and due to the fine structure of the coating surfaces, considerably better sliding properties have been achieved than with smooth coatings.
at/ that/
Det har til og med vist seg slike belegg også uten anvendelse av skismurning forbedrer stigeevnen på de .fleste snetyper i til-strekkelig grad uten at dette vesentlig går ut over glideevnen. Dette muliggjør derfor at belegget ifølge oppfinnelsen kan anvendes som et"skismurningfritt belegg". It has even been shown that such coatings, even without the use of ski masonry, improve the climbing ability on most types of snow to a sufficient extent without this significantly affecting the gliding ability. This therefore makes it possible for the coating according to the invention to be used as a "ski bricking-free coating".
Som råmateriale for fremstilling av poreholdige belegg er duroplastiske og termoplastiske, spesielt høymolekylære termoplastiske, plaster egnede. Belegg på polyurethanbasis har vist seg å være meget godt egnede. Spesielt gode resultat oppnås ved anvendelse av folier fremstilt fra høymolekylært polyethylen, fortrinnsvis lavtrykkspolyethylen, med en molekylvekt på 3-4 millioner ved sintring under trykk og ved samtidig opplokring ved innpressing av gass. Foliene. ha3: en egenvekt på 0,3-0,7 g/cm 3, fortrinnsvis As raw material for the production of porous coatings, duroplastic and thermoplastic, especially high molecular weight thermoplastic, plastics are suitable. Polyurethane-based coatings have proven to be very suitable. Particularly good results are achieved by using foils made from high-molecular polyethylene, preferably low-pressure polyethylene, with a molecular weight of 3-4 million by sintering under pressure and by simultaneous heating by pressing in gas. The foils. ha3: a specific gravity of 0.3-0.7 g/cm 3, preferably

Mens det oppstår vanskeligheter med å få skismurningen til While difficulties arise in getting the ski masonry done
å hefte til belegget ved anvendelse av tette folier på basis av høymolekylært lavtrykkspolyethylen med en molekylvekt på 3-4 millioner og en egenvekt på over 0,9 g/cm 3, slik at det ikke fås en ekte binding, kan problemet i forbindelse med skismurningens vedheftning overvinnes ved hjelp av folier med åpen struktur. to adhere to the coating by using tight foils based on high molecular weight low-pressure polyethylene with a molecular weight of 3-4 million and a specific gravity of over 0.9 g/cm 3, so that no real bond is obtained, the problem in connection with the ski walling adhesion is overcome by means of foils with an open structure.
Skibelegget kan. ved anvendelse av folier festes på skien f.eks. ved påklebing med. et egnet 2-komponentepoxydharp.ikslim eller fortrinnsvis med lim som foreligger som tynne filmer og der-ved sikrer en jevn klebefilmtykkelse. The ski covering can. when using foils are attached to the ski, e.g. by sticking with. a suitable 2-component epoxy resin glue or preferably with glue that is present as thin films and thereby ensures a uniform adhesive film thickness.
Det er også mulig å anvende de porøse folier i laminert form fremstilt i en egen arbeidsoperasjon hvor de belegges med andre plaster. It is also possible to use the porous foils in laminated form produced in a separate work operation where they are coated with other plasters.
