Description
Fremgangsmåte til fremstilling av vedheftende overtrekk på polytetralfuoretylen. Process for the production of adhesive coatings on polytetrafluoroethylene.
En av polytetrafluoretylenets karak-teristiske egenskaper er dets manglende evne til under vanlige forhold å hefte ved andre materialer. Denne enestående egenskap har forårsaket forskjellige fordelak-tige anvendelser av denne harpiks. Således er f. eks. overtrekk av polytetrafluoretylen brukt på metallvalser som kommer i kontakt med smeltet polyetylen, hvorved disse overtrekk tjener det formål å forhindre vedheftning av polyetylenet til metallval-sen. Polytetrafluoretylen er også brukt på lignende måte i forskjellige mekanismer, hvor et element med polytetrafluoretylen-overflate er anordnet glidbart i forhold til et annet element. I slike anvendelser og i tallrike andre anvendelser frembringer polytetrafluoretylenets ikke-vedhef tende egenskaper verdifulle og nyttige resultater. Men på den annen side er den nevnte sær-lige egenskap uønsket ved visse andre praktiske anvendelser av polytetrafluoretylen. Således har f. eks. problemet dan-nelse av en vedheftende binding mellom polytetrafluoretylenoverflater og overflater på andre materialer som metall, glass, plastmaterialer andre enn polytetrafluoretylen eller to forskjellige polytetrafluor-etylens overflater vært ytterst besværlig. Der er utarbeidet visse metoder til å binde metallhinder til polytetrafluoretylen for herved å oppnå et mellomsjikt som kan bindes til andre materialer. Der er også brukt forskjellige andre kostbare metoder for å oppnå det ønskede resultat. Ingen av disse metoder har imidlertid vært fullsten-dig tilfredsstillende fra synspunktet effek-tivitet og billighet. One of polytetrafluoroethylene's characteristic properties is its inability to adhere to other materials under normal conditions. This unique property has caused various advantageous applications of this resin. Thus, e.g. coatings of polytetrafluoroethylene used on metal rolls that come into contact with molten polyethylene, whereby these coatings serve the purpose of preventing adhesion of the polyethylene to the metal roll. Polytetrafluoroethylene is also used in a similar way in various mechanisms, where an element with a polytetrafluoroethylene surface is arranged to slide in relation to another element. In such applications and in numerous other applications, the non-adhesive properties of polytetrafluoroethylene produce valuable and useful results. But on the other hand, the aforementioned special property is undesirable in certain other practical applications of polytetrafluoroethylene. Thus, e.g. the problem of forming an adhesive bond between polytetrafluoroethylene surfaces and surfaces on other materials such as metal, glass, plastic materials other than polytetrafluoroethylene or two different polytetrafluoroethylene surfaces has been extremely difficult. Certain methods have been developed to bond metal barriers to polytetrafluoroethylene in order to achieve an intermediate layer that can be bonded to other materials. Various other expensive methods have also been used to achieve the desired result. However, none of these methods have been completely satisfactory from the point of view of effectiveness and cheapness.
Ved hjelp av foreliggende oppfinnelse skaffes der en fordelaktig fremgangsmåte til fremstilling av et vedheftende overtrekk på polytetrafluoretylen. Dette overtrekk er av den art at andre materialer ved klebning kan festes til polytetrafluoretylen. With the help of the present invention, an advantageous method for producing an adhesive coating on polytetrafluoroethylene is obtained. This covering is such that other materials can be attached to polytetrafluoroethylene by gluing.
Det er funnet at polytetrafluoretylenoverflater endres i bemerkelsesverdig grad når de bringes i kontakt med en oppløs-ning av et alkalimetall i flytende ammoniakk. Det er videre funnet at de overflater man får herved danner i høy grad effektive midler til ved klebning å sammenbinde polytetrafluoretylenoverflater og andre overflater. It has been found that polytetrafluoroethylene surfaces change to a remarkable degree when brought into contact with a solution of an alkali metal in liquid ammonia. It has further been found that the surfaces obtained in this way form highly effective means for bonding together polytetrafluoroethylene surfaces and other surfaces by gluing.
Den overflate som frembringes ved reaksjon av polytetrafluoretylen med en oppløsning av et alkalimetall i flytende ammoniakk består av et sort klebende residuum som åpenbart dannes ved dehalo-genering av den polymeres overflate. Den nevnte sorte overflate er vanskelig om ikke umulig å fjerne fra polytetrafluoretylen ved skuring eller gnidning eller ved hjelp av andre fysikalske metoder. Denne overflate lar seg klebe fast sammen med andre overflater som overflater på metaller, plastmaterialer, glass, tre osv. The surface produced by the reaction of polytetrafluoroethylene with a solution of an alkali metal in liquid ammonia consists of a black sticky residue which is obviously formed by dehalogenation of the polymer's surface. The aforementioned black surface is difficult if not impossible to remove from polytetrafluoroethylene by scrubbing or rubbing or using other physical methods. This surface can be stuck together with other surfaces such as surfaces on metals, plastic materials, glass, wood, etc.
I det følgende beskrives som eksempler noen utførelsesformer ifølge oppfinnelsen. In the following, some embodiments according to the invention are described as examples.
Eksempel I. - Example I. -
Et rent, tørt ark polytetrafluoretylen ble dyppet ned i en 1 pst.'s oppløsning av .metallisk natrium i vannfri flytende ammoniakk. Herved dannet det seg et mørke-brunt til sort overtrekk på arkets overflate. Den således dannede overflate ble sammenklebet med et ark av metallisk aluminium under anvendelse av et surgjort fenol-formaldehydklebestoff under et lett trykk og ved en temperatur på 60° C. Ved-heftningen var god. Forsøket ble gjentatt under anvendelse av to ark polytetrafluoretylen som begge ble underkastet modifi-kasjon av overflaten som beskrevet ovenfor istedetfor et polytetrafluoretylenark og et aluminiumark. Også herved oppnåddes der en god sammenklebning. A clean, dry sheet of polytetrafluoroethylene was dipped into a 1 percent solution of metallic sodium in anhydrous liquid ammonia. This formed a dark brown to black coating on the surface of the sheet. The surface thus formed was bonded to a sheet of metallic aluminum using an acidified phenol-formaldehyde adhesive under light pressure and at a temperature of 60° C. Adhesion was good. The experiment was repeated using two sheets of polytetrafluoroethylene, both of which were subjected to surface modification as described above, instead of a polytetrafluoroethylene sheet and an aluminum sheet. Here too, a good adhesion was achieved.
Eksempel 2: Example 2:
Et ark polytetrafluoretylen behandlet med en oppløsning av natrium i flytende ammoniakk ble sammenklebet med aluminium under anvendelse av en epoksyharpiks i form av handelsvare som klebemiddel. Forøvrig gikk man frem som beskrevet i eksempel 1. På samme måte ble polytetrafluoretylenark sammenklebet med stålplater. De resulterende sammenklebninger ble prøvet på skjærfasthet og strekkfasthet med resultater som angitt i følgende tabell: A sheet of polytetrafluoroethylene treated with a solution of sodium in liquid ammonia was bonded to aluminum using a commercial grade epoxy resin as an adhesive. Otherwise, the procedure was as described in example 1. In the same way, polytetrafluoroethylene sheets were glued together with steel plates. The resulting bonds were tested for shear strength and tensile strength with results as indicated in the following table:
Eksempel 3: Example 3:
Et polytetrafluoretylen ble behandlet med en oppløsning av natrium i flytende ammoniakk, således som ovenfor angitt og den resulterende karboniserte overflate ble klebet til en treoverflate (ek) under anvendelse av epoksyharpiks i form av handelsvare som klebestoff. Det ble herved oppnådd en god sammenklebning. A polytetrafluoroethylene was treated with a solution of sodium in liquid ammonia as above and the resulting carbonized surface was glued to a wooden surface (oak) using commercial grade epoxy resin as an adhesive. A good adhesion was thereby achieved.
De sammenklebninger som fåes ved hjelp av fremgangsmåten ifølge kravet er i sin alminnelighet motstandsdyktige over-for angrep av kjemikalier mot hvilke selve klebestoffet og det materiale som polyte-trafluoretylenet er sammenklebet med er motstandsdyktige. Således motsto f. eks. en sammenklebning mellom to polytetrafluoretylenoverflater ifølge forliggende oppfin- The adhesions obtained by means of the method according to the claim are generally resistant to attack by chemicals to which the adhesive itself and the material with which the polytetrafluoroethylene is bonded are resistant. Thus resisted e.g. a bonding between two polytetrafluoroethylene surfaces according to the present invention
nelse under anvendelse av et fenol-formaldehydklebestoff kokning i flere dager i vandig 20 pst.'s saltsyre. I lignende prøver sviktet ikke sammenklebninger fremstillet ved bruk av epoksyharpikser etter 21 dager i kontakt med kokende 20 pst.'s saltsyre. nelse using a phenol-formaldehyde adhesive boiling for several days in aqueous 20 per cent hydrochloric acid. In similar tests, bonds made using epoxy resins did not fail after 21 days in contact with boiling 20 percent hydrochloric acid.
Som nevnt i de foregående eksempler bør overflatene av polytetrafluoretylen før sammenklebningen være rene og tørre. Det er således i alminnelighet tilrådelig å fjerne fett osv. ved hjelp av organiske oppløs-ningsmidler. As mentioned in the previous examples, the surfaces of polytetrafluoroethylene should be clean and dry before bonding. It is therefore generally advisable to remove grease etc. using organic solvents.
Foreliggende oppfinnelse er høyst fordelaktig ved fremstilling av forskjellige gjenstander som kan bestå av flere sammenklebede deler av polytetrafluoretylen, eller av dette materiale sammenklebet med andre materialer. Elektriske isolasjoner, spiralrør og forskjellige gjenstander som er forsterket med polytetrafluoretylen i The present invention is highly advantageous in the production of various objects which can consist of several glued together parts of polytetrafluoroethylene, or of this material glued together with other materials. Electrical insulations, spiral pipes and various items reinforced with polytetrafluoroethylene i
form av fibrer er eksempler på produkter form of fibers are examples of products
som kan fremstilles ved hjelp av foreliggende oppfinnelse. which can be produced using the present invention.
