Description
Wärmefester lösungsmittelhaltiger Klebstoff auf Nitnlkautschukgrundlage Die Erfindung betrifft einen wärmefesten lösungsmittelhaltigen Klebstoff auf Nitrilkautschukbasis, der zum Vorkleben von unvulkanisiertem und vulkanisiertem Nitril- und Fluorkautschuk mit Metall oder fluororganischen Kunststoffen dient, wobei die Klebstellen die Einwirkung von Temperaturen zwischen -50 und +170"C aushalten.Heat-resistant, solvent-based adhesive based on nitrile rubber The invention relates to a heat-resistant solvent-containing adhesive based on nitrile rubber, for pre-gluing unvulcanized and vulcanized nitrile and fluororubber with metal or organofluorine plastics is used, whereby the adhesive points the action withstand temperatures between -50 and +170 "C.
Unter Fluorkautschuken werden elastomere Mischpolymere von Fluorderivaten der Athylenreihe, wie Mischpolymere von Chlorfluoräthylen oder Hexafluorpropylen mit Vinylidenfluorid oder von Hexa-.fluorpropylen mit Tetrafluoräthylen, und unter fluororganischen Kunststoffen Polymere und Mischpolymere von fluorierten Athylenen, wie Polytetrafluoräthylen, verstanden. Fluororubbers refer to elastomeric copolymers of fluorine derivatives of the ethylene series, such as copolymers of chlorofluoroethylene or hexafluoropropylene with vinylidene fluoride or hexa-.fluoropropylene with tetrafluoroethylene, and under organofluorine plastics Polymers and copolymers of fluorinated ethylenes, such as polytetrafluoroethylene understood.
Klebstoffe auf der Grundlage von Nitrilkautschuk zum Verkleben verschiedenartiger Materialien sind bekannt, jedoch halten diese Klebstoffe nur Temperaturen bis 150"C aus; außerdem eignen sich die meisten bekannten Klebstoffe nicht zum Verkleben von unvulkanisiertem und vulkanisiertem Nitril-und Fluorkautschuk mit Metall und fiuororganischen Kunststoffen, wofür bisher nur Epoxy- und Silikonharze in Frage kamen. Letztere sind aber meistens giftige Stoffe, welche eine umfassende Anwendung dieser Harze als Ausgangsstoffe für Klebstoffe in einigen Fällen verhindern. Nitrile rubber-based adhesives for bonding various types of glue Materials are known, but these adhesives only hold temperatures of up to 150 "C the end; in addition, most of the known adhesives are not suitable for bonding unvulcanized and vulcanized nitrile and fluororubber with metal and organofluoric Plastics, for which previously only epoxy and silicone resins could be used. Latter but are mostly poisonous substances, which make extensive use of these resins as starting materials for adhesives in some cases.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diese Mängel zu beseitigen. The present invention addresses these shortcomings to eliminate.
Der erfindungsgemäße wärmefeste lösungsmittelhaltige Klebstoff auf Nitrilkautschukbasis ist dadurch gekennzeichnet, daß er außer plastiziertem Nitrilkautschuk und Lösungsmittel noch Resorcinfurfurolharz enthält. The heat-resistant solvent-based adhesive according to the invention Nitrile rubber base is characterized by the fact that it contains plasticized nitrile rubber and solvent still contains resorcinol furfural resin.
Ein bevorzugt zusammengesetzter Klebstoff gemäß der Erfindung besteht aus 1 Gewichtsteil plastiziertem Nitrilkautschuk, 1 Gewichtsteil Resorcinfurfurolharz, 8 Gewichtsteilen Lösungsmittel, wie Aceton oder Formalglykol (Dioxolan-1,3) der Formel (vgl. E. H. R o d a, »Chemistry of carbon compounds«, Vol. I. A, 1951).A preferably composed adhesive according to the invention consists of 1 part by weight of plasticized nitrile rubber, 1 part by weight of resorcinol furfural resin, 8 parts by weight of a solvent such as acetone or formalglycol (1,3-dioxolane) of the formula (cf. EH Roda, "Chemistry of carbon compounds", Vol. I. A, 1951).
Der erfindungsgemäße Klebstoff ist ebenso leicht herstellbar wie verwendbar. Die mit dem Klebstoff bewirkten Verklebungen von unvulkanisiertem und vulkanisiertem Nitril- und Fluorkautschuken mit Metall oder fluororganischen Kunststoffen sind benzinfest und halten heiße Vulkanisationsprozesse aus. Im Temperaturbereich von - 50 bis +1709C werden sie nicht plastisch und zeigen keine Zersetzungserscheinungen. Sie sind daher zum Verkleben von Fluor- und Nitrilkautschuk untereinander und mit andersartigen fiuororganischen Kunststoffen sowie als Metallklebstoff zur Herstellung von Kautschuk-Metall-Schichtstoffen auf hochleistungsfähigen Fließstraßen vorzüglich geeignet. The adhesive according to the invention is just as easy to manufacture as usable. The bonds of unvulcanized and vulcanized nitrile and fluororubbers with metal or organofluorine plastics are petrol-proof and can withstand hot vulcanization processes. In the temperature range from - 50 to + 1709C they do not become plastic and show no signs of decomposition. They are therefore used to bond fluorine and nitrile rubber to one another and to different types of organofluorine plastics as well as metal adhesives for production of rubber-metal laminates on high-performance flow lines excellent suitable.
Beispiel Das Resorcinfurfurolharz wird wie folgt bereitet: Ein Gemisch von Resorcin, Furfurol und Äthanol wird 1 Stunde bei 40"C und nach Einführung eines Alkalikatalysators noch 1 Stunde bei 40"C erwärmt, nach Erhöhung der Temperatur auf 90 bis 102"C 15 Minuten bei dieser Temperatur gehalten und schließlich im Vakuum bis zum Erhärten getrocknet. Example The resorcinol furfural resin is prepared as follows: A mixture of resorcinol, furfural and ethanol is 1 hour at 40 "C and after the introduction of a Alkali catalyst heated for 1 hour at 40 "C, after increasing the temperature kept at 90 to 102 "C for 15 minutes at this temperature and finally in a vacuum dried until hardened.
Ein Leimmischer wird mit 1 Gewichtsteil plastiziertem Nitrilkautschuk in Form von kleinen Stückchen, 8 Gewichtsteilen Formalglykol (Dioxolan-1,3) und 1 Gewichtsteil des Resorcinfurfurolharzes beschickt. Die erhaltene Masse verrührt man 1,5 bis 2 Stunden. Formalglykol wird in zwei Stufen, nämlich zu Beginn des Mischens und nachdem sich eine gleichartige aufgequollene Masse gebildet hatte, zugesetzt; danach wird die Masse ergänzend gerührt. A glue mixer is loaded with 1 part by weight of plasticized nitrile rubber in the form of small pieces, 8 parts by weight of formal glycol (1,3-dioxolane) and 1 part by weight of the resorcinol furfural resin is charged. The mass obtained is stirred one 1.5 to 2 hours. Formal glycol comes in two stages, namely at the start of mixing and after a similar swollen mass had formed, added; then the mass is additionally stirred.
Die Festigkeit der Verklebungen mit Hilfe des Klebstoffes ist in der Tabelle I angeführt. The strength of the bonds with the help of the adhesive is in Table I listed.
