Abstract
Det beskrives et smøremiddel omfattende harpiks, olje eller fett, fortrinnsvis av vegetabilsk eller animalsk opprinnelse, og eventuelt voks. Videre beskrives anvendelse av smøremidlet ved boring eller gjenging i metall, spesielt i stål og aluminium.A lubricant comprising resin, oil or grease, preferably of vegetable or animal origin, and optionally wax is described. Furthermore, the use of the lubricant in drilling or threading in metal, especially in steel and aluminum, is described.
Description
Denne oppfinnelse angår et preparat med smørende virkning og anvendelse av preparatet som smøremiddel ved boring eller gjenging i metall. This invention relates to a preparation with a lubricating effect and the use of the preparation as a lubricant when drilling or threading in metal.
De smøremidler som hittil er blitt benyttet ved boring eller gjenging i metall, spesielt stål og aluminium, har den ulempe at de etter bare kort tids boring eller gjenging helt eller delvis taper sin smørende virkning. Nytt smøremiddel må stadig tilføres til hullet. Det er hittil heller ikke blitt frem-skaffet noe smøremiddel som gir glatte overflater direkte ved boringen eller gjengingen, uten at det er nødvendig å foreta noen etterbehandling av hullet for å oppnå den ønskede glatthet. The lubricants that have so far been used for drilling or threading in metal, especially steel and aluminium, have the disadvantage that after only a short time of drilling or threading, they completely or partially lose their lubricating effect. New lubricant must be constantly added to the hole. To date, no lubricant has been produced which provides smooth surfaces directly during drilling or threading, without it being necessary to carry out any post-treatment of the hole in order to achieve the desired smoothness.
En del av de smøremidler som hittil er blitt benyttet, inneholder komponenter som under boringen eller gjengingen avgir stoffer som dels er irriterende for personer i umiddel-bar nærhet av boringen og dels sågar kan være skadelige ved innåndning eller ved hudkontakt. Store summer har således måttet legges ned i tiltak for å beskytte personell i form av f.eks. avtrekk over arbeidsplassen og i rensning av luft-utslippet fra arbeidslokalet. Some of the lubricants that have been used to date contain components which, during drilling or threading, release substances which are partly irritating to people in the immediate vicinity of the drilling and partly can even be harmful if inhaled or in contact with the skin. Large sums have thus had to be spent on measures to protect personnel in the form of e.g. extraction above the workplace and in cleaning the air emissions from the workplace.
Ved hjelp av oppfinnelsen tilveiebringes det et smøre-middel som både er langtidsvirkende og er uskadelig for om-givelsene . With the help of the invention, a lubricant is provided which is both long-lasting and harmless to the environment.
Preparatet ifølge oppfinnelsen utgjøres av 3-5 vektdeler av en naturlig forekommende harpiks, 3-6 vektdeler av en olje eller et fett av vegetabilsk eller animalsk opprinnelse og eventuelt 1-3 vektdeler voks, samt eventuelt mindre mengder av vanlige tilsetninger. Oppfinnelsen angår også anvendelse av preparatet som smøremiddel ved boring eller gjenging i metall, spesielt i stål eller aluminium. The preparation according to the invention consists of 3-5 parts by weight of a naturally occurring resin, 3-6 parts by weight of an oil or fat of vegetable or animal origin and optionally 1-3 parts by weight of wax, as well as possibly smaller quantities of usual additives. The invention also relates to the use of the preparation as a lubricant when drilling or threading in metal, especially in steel or aluminium.
Ved anvendelse av preparatet ifølge oppfinnelsen som smøremiddel ved boring eller gjenging i metaller, spesielt i stål og aluminium, oppnåes en meget lengre virkning enn hva som hittil har vært mulig. Preparatet tilbakeholdes på boret eller gjengetappen i form av et smørende skikt under boringen eller gjengingen, samtidig som det oppnåes en meget glatt overflate i hullet. I de fleste tilfeller er det ikke nødven-dig med noen etterbehandling. Dette er særlig overraskende ved boring eller gjenging i aluminium, som er et materiale som det er kjent er meget vanskelig å bearbeide. When using the preparation according to the invention as a lubricant when drilling or threading in metals, especially in steel and aluminium, a much longer effect is achieved than has been possible up to now. The preparation is retained on the drill or threaded tap in the form of a lubricating layer during drilling or threading, while at the same time a very smooth surface is achieved in the hole. In most cases, no post-processing is necessary. This is particularly surprising when drilling or threading in aluminium, which is a material that is known to be very difficult to process.
Årsaken til at oljens eller fettets smørende virkning bibeholdes på boret eller gjengetappen, synes å være at harpiksen og den eventuelle voks danner en hinne på boret eller gjengetappen, og at denne hinne tilbakeholder oljen eller fettet, som derved kan utøve sin smørende virkning i lang tid. The reason why the lubricating effect of the oil or grease is maintained on the drill or threaded stud seems to be that the resin and any wax form a film on the drill or threaded stud, and that this film retains the oil or grease, which can thereby exert its lubricating effect for a long time .
Oljen eller fettet er en animalsk eller vegetabilsk olje eller fett for å unngå skadevirkninger for brukeren. Eksempelvis kan vanlige vegetabilske eller animalske oljer som benyttes som matolje, anvendes, likesom smør eller ister. The oil or fat is an animal or vegetable oil or fat to avoid harmful effects for the user. For example, ordinary vegetable or animal oils that are used as cooking oil can be used, as can butter or lard.
Voks tilsettes preparatet dersom det ønskes en mer pastalignende konsistens. Jo mer voks det tilsettes, desto mer pastalignende blir preparatets konsistens. Den foretrukne voks er bivoks på grunn av dens uskadelighet for mennesker. Dersom voks utelates, fåes en skjærolje, dvs. et flytende preparat. Wax is added to the preparation if a more paste-like consistency is desired. The more wax that is added, the more paste-like the consistency of the preparation becomes. The preferred wax is beeswax because of its harmlessness to humans. If wax is omitted, a cutting oil is obtained, i.e. a liquid preparation.
Preparatet fremstilles ved at de ulike bestanddeler smeltes sammen. Harpiks har normalt en smeltetemperatur på The preparation is made by melting the various ingredients together. Resin normally has a melting temperature of
ca. 135°C, men blandet med de øvrige bestanddeler i preparatet smelter den allerede ved 90°C. about. 135°C, but mixed with the other ingredients in the preparation it already melts at 90°C.
En annen fordel som knytter seg til den foreliggende oppfinnelse, er derfor den at det ikke kreves noe eget opp-løsningsmiddel ved fremstillingen. Derved unngåes ytterligere et risikomoment ved de tidligere kjente smøremidler. Another advantage linked to the present invention is therefore that no separate solvent is required during production. Thereby, a further element of risk with the previously known lubricants is avoided.
Andelen av de forskjellige bestanddeler i preparatet kan variere innenfor de ovenfor angitte grenser, avhengig av hvilken konsistens man ønsker hos det ferdige preparat. The proportion of the various components in the preparation may vary within the limits stated above, depending on the desired consistency of the finished preparation.
Preparatet kan også inneholde mindre mengder av andre bestanddeler, såsom f.eks. fyllmidler av forskjellige typer, eller andre tilsetninger som ikke påvirker preparatets ovenfor omtalte virkning. The preparation may also contain smaller amounts of other ingredients, such as e.g. fillers of different types, or other additives that do not affect the above-mentioned effect of the preparation.
Harpiksen som benyttes, er naturlig forekommende harpiks, f.eks. kolofonium, som er et plantesaftprodukt av bar-trær. Også andre naturlig forekommende harpikser kan benyttes. The resin used is naturally occurring resin, e.g. rosin, which is a plant sap product of bar trees. Other naturally occurring resins can also be used.
