Description
Skobunn. Shoe sole.
Den foreliggende oppfinnelse vedrører en skobunn, særlig for klogger, og det som kjennetegner oppfinnelsen er at den består av plastbundete mineralullsfibre. The present invention relates to a shoe sole, particularly for clogs, and what characterizes the invention is that it consists of plastic-bound mineral wool fibres.
Ved fremstilling av bunner for klogger skjæres det ut maskinelt av en plate av helt trevirke et emne som deretter underkastes ytter-ligere bearbeidelse til den nøyaktige form som ønskes samt pussing. Fremstillingen av skobunner av denne type på konvensjonell måte er derfor relativt komplisert og kostnadskrevende. In the production of bases for clogs, a blank is machined out of a sheet of solid wood, which is then subjected to further processing to the exact desired shape as well as plastering. The production of shoe soles of this type in a conventional manner is therefore relatively complicated and costly.
Formålet med oppfinnelsen er å frembringe en skobunn som kan fremstilles på enklere måte enn slike av tre og med lave kostnader, og som oppviser stort sett samme gode egenskaper som skobunner av tre, særlig god slitestyrke og tilstrekkelig porøsitet for å ikke hindre føttene i å puste. The purpose of the invention is to produce a shoe sole that can be produced in a simpler way than those made of wood and at low cost, and which exhibits largely the same good properties as wooden shoe soles, particularly good wear resistance and sufficient porosity so as not to prevent the feet from breathing .
Det har vist seg at skobunner med stort sett like gode egenskaper som skobunner av helt trevirke kan fremstillet av plastbundet mineralull slik at fremstillingen blir enklere og mindre kostnadskrevende enn den konvensjonelle fremstilling av skobunner av trevirke-, idet man kan forme og herde plastimpregnert mineralull til nøyaktig den form man ønsker å gi skobunnen, slik at kostnadskrevende etterbearbeidelse og pussing blir overflødig. It has been shown that shoe soles with largely the same good properties as shoe soles made entirely of wood can be produced from plastic-bonded mineral wool, so that the manufacture is simpler and less costly than the conventional manufacture of wooden shoe soles, since plastic-impregnated mineral wool can be shaped and hardened to exact the shape you want to give the bottom of the shoe, so that costly post-processing and sanding becomes redundant.
For dette formål kan man anvende mineralullsmaterialet av For this purpose, the mineral wool material can be used
alle typer, så som glassull, stenull og slaggull, som plast for binding av mineralullen anvendes det fortrinsvis en herdeplast, hensiktsmessig en fenolplast, særlig et fenolharpiksbindemiddel som er basert på fenol og formaldhyd. all types, such as glass wool, rock wool and beaten gold, as plastic for binding the mineral wool, a thermosetting plastic is preferably used, suitably a phenolic plastic, in particular a phenolic resin binder which is based on phenol and formaldehyde.
Man kan fremstille gjenstander av plastbundet mineralull Objects can be produced from plastic-bound mineral wool
med varierende jvolumvekt og hårdhet ved å variere mengden plastimpregnert mineralull som anbringes i formen. ,For det foreliggende formål anvendes det hensiktsmessig plastbundet mineralull med 15-25$ plast. Særlig anvendes fenolplastbundet glassull med en volumvekt på 300-500 kg/m^, og med en hårdhet som stort sett tilsvarer hårdheten hos trevirke. For eksempel er det med utmerket resultat fremstilt skobunner av glassull med 18-20$ fenolharpiksbindemiddel basert på fenol og formaldhyd. with varying jvolume weight and hardness by varying the amount of plastic-impregnated mineral wool placed in the mold. ,For the present purpose, plastic-bound mineral wool with 15-25$ of plastic is used. In particular, phenol plastic-bonded glass wool is used with a volume weight of 300-500 kg/m^, and with a hardness that largely corresponds to the hardness of wood. For example, shoe soles made of glass wool with 18-20$ phenol resin binder based on phenol and formaldehyde have been produced with excellent results.
For fremstilling av skobunnen ifølge foreliggende oppfinnelse kan man for eksempel som utgangsmateriale anvende handelsvanlig glassull som er impregnert med fenolharpiksbindemiddel og som er fremstilt ved sprøyting av fenolharpiksbindemidlet, fortrinsvis i en mengde av 18-20 vektsprosent beregnet av glassullens vekt, inn i de spunnete glassfibrer. De impregnerte fibrene anbringes i en form hvis formhulrom tilsvarer den ønskete skobunns form. Mengden impregnerte mineralfibrer som anbringes i formen avpasses for opp-nåelse av ønsket volumvekt hos den ferdige skobunn, fortrinsvis 300-500 kg/m^. Formen lukkes og oppvarmes til en temperatur hvor fenolharpiksbindemidlet herder og binder sammen mineralullfibrene, vanligvis 170-l80°C. For the production of the shoe sole according to the present invention, one can for example use as a starting material commercial glass wool which is impregnated with a phenolic resin binder and which is produced by spraying the phenolic resin binder, preferably in an amount of 18-20% by weight calculated from the weight of the glass wool, into the spun glass fibers. The impregnated fibers are placed in a mold whose mold cavity corresponds to the shape of the desired shoe sole. The amount of impregnated mineral fibers placed in the mold is adjusted to achieve the desired volume weight of the finished shoe sole, preferably 300-500 kg/m^. The mold is closed and heated to a temperature where the phenolic resin binder hardens and binds the mineral wool fibers together, usually 170-180°C.
Det fenolplastbundete mineralullsmaterialet er et slitesterkt materiale og er meget egnet for skobunner, særlig for slike sko som klogger og sandaler. Materialet inneholder luftporer slik at føttene kan puste, og derfor sveller ikke føttene når man anvender sko med bunner av dette materialet, slik tilfellet er dersom man anvender bunner av bare plast, som tidligere er blitt anvendt som materiale i skobunnet, for eksempel klogger. The phenol plastic-bound mineral wool material is a hard-wearing material and is very suitable for shoe soles, especially for such shoes as clogs and sandals. The material contains air pores so that the feet can breathe, and therefore the feet do not swell when you use shoes with soles made of this material, as is the case if you use soles made only of plastic, which has previously been used as a material in the sole of shoes, for example clogs.
Skobunnene ifølge den 'foreliggende oppfinnelse kan på vanlig måte utstyres med en dekkplate på oversiden, for eksempel av lær eller finer , og en slitesåle på undersiden, for eksempel av gummi. The shoe soles according to the present invention can in the usual way be equipped with a cover plate on the upper side, for example of leather or veneer, and a wear sole on the underside, for example of rubber.
