Das Hauptpatent 1469 832 betrifft ein Gleitlager oder Lagermaterial aus einer Mischung von feinteiligem faserigem Polytetrafluoräthylen und einem Epoxyharz gegebenenfalls mit Füllstoff. Der Anteil an Epoxyharz in dem Lagermaterial kann zwischen 20 und 40% betragen. Als Füllstoff kann in üblicher Weise ein Metall oder Molybdänsulfid enthalten sein. Die Herstellung des Gleitlagers oder Lagermaterials nach dem Hauptpatent geschieht in der Weise, daß ein Pulvergemisch von Epoxyharz und Polytetrafluoräthylen einer Scherbeanspruchung ausgesetzt wird, bis das Polytetrafluoräthylen in faserige Form übergeführt worden ist. Diese Masse wird dann geformt und gehärtet. Bei der Härtung kann es im Hinblick auf die Anwendung des Lagermaterials zweckmäßig sein, bis zu Sintertemperatur des Polytetrafluoräthylens zu erhitzen. The main patent 1469 832 relates to a plain bearing or bearing material made of a mixture of finely divided fibrous polytetrafluoroethylene and an epoxy resin, optionally with filler. The proportion of Epoxy resin in the stock material can be between 20 and 40%. As a filler can be used in usual Way to contain a metal or molybdenum sulfide. The manufacture of the plain bearing or bearing material according to the main patent is done in such a way that a powder mixture of epoxy resin and polytetrafluoroethylene is subjected to shear stress until the polytetrafluoroethylene is converted into fibrous form has been. This mass is then shaped and hardened. When hardening it can be in terms of Use of the storage material is advisable to heat up to the sintering temperature of the polytetrafluoroethylene.
Die Erfindung betrifft nun eine Abwandlung des Lagermaterials nach dem Hauptpatent, in dem an Stelle des Epoxyharzes das faserige Polytetrafluoräthylen in einem Kresolformaldehyd- oder Phenolformaldehydharz, einem Polyurethanharz oder einem vulkanisierten Kautschuk eingebettet ist.The invention now relates to a modification of the bearing material according to the main patent in which at Instead of the epoxy resin, the fibrous polytetrafluoroethylene in a cresol-formaldehyde or phenol-formaldehyde resin, a polyurethane resin or a vulcanized rubber is embedded.
Beim Aufbau der erfindungsgemäßen Lagermaterialien zur Herstellung der Gleitlager muß ein Harz verwendet werden, welches zweckmäßigerweise wärmehärtend ist, eine ausreichende Festigkeit und Abriebfestigkeit besitzt, eine gute Haftung auf der Unterlage bzw. dem Stützmaterial erbringt und in ungehärtetem Zustand im Gemisch mit Polytetrafluoräthylen und gegebenenfalls anderen Füllstoffen eine solche Viskosität besitzt, daß das pulverförmige Polytetrafluoräthylen unter den Druck- und Scherbelastungen in die faserige Form überführt werden kann. Als Füllstoff kann wie üblich Graphit, ein Metall oder Molybdänsulfid angewandt werden. Auch kann man in üblicher Weise ein Verstärkungsmaterial einbringen.When constructing the bearing materials according to the invention for producing the plain bearings, a resin must be used which is suitably thermosetting, sufficient strength and abrasion resistance can be used possesses, provides good adhesion to the base or the support material and in uncured Condition in a mixture with polytetrafluoroethylene and possibly other fillers such Viscosity possesses that the powdery polytetrafluoroethylene under the pressure and shear loads can be converted into the fibrous form. As a filler graphite, a metal or molybdenum sulfide can be used as usual. You can also use the usual Way introduce a reinforcement material.
Das erfindungsgemäße Lagermaterial läßt sich direkt als Gleitlager, also ohne Stützschale od. dgl., anwenden. Es ist jedoch auch möglich, es in eine Lagerschale oder eine Stützschale einzuarbeiten.The bearing material according to the invention can be used directly as a plain bearing, that is to say without a support shell or the like. However, it is also possible to work it into a bearing shell or a support shell.
Diese Masse aus in Harz eingebettetem faserigem Polytetrafluoräthylen wird nach dem angestrebten Verwendungszweck verarbeitet z. B.This mass of fibrous polytetrafluoroethylene embedded in resin is sought after Purpose processed z. B.
1. Formen zu Folien oder Platten unter Druck und Wärme (z. B. 150° C 5 bis 30 min je Materialstärke, Preßdruck etwa 0,8 bis 1,6 kg/mm2).1. Shaping into foils or plates under pressure and heat (e.g. 150 ° C. 5 to 30 minutes per material thickness, pressure about 0.8 to 1.6 kg / mm 2 ).
2. Durcharbeiten auf einem Walzenstuhl mit einer solchen Schlitzweite, daß man eine Folie mit einer Stärke von 0,0127 bis 0,127 mm erhält. Diese Folie kann dann auf ein Stützmaterial als Gleitschicht aufgetragen werden, und zwar:2. Working through on a roller frame with a slot width such that you can use a slide a thickness of 0.0127 to 0.127 mm. This film can then be used as a support material Sliding layer are applied, namely:
!5 a) auf ein Band aus Aluminiumlegierung oder Stahl, sandgestrahlt und entfettet, in 5 min bei 150° C unter einem Preßdruck von etwa 0,8 kg/ mm2. Die Bänder kann man mit einem wärmebeständigen Kleber zur Verbesserung der Adhäsion vorbehandeln.5 a) on a strip made of aluminum alloy or steel, sandblasted and degreased, in 5 min at 150 ° C under a pressure of about 0.8 kg / mm 2 . The tapes can be pretreated with a heat-resistant adhesive to improve adhesion.
b) Man kann sie mit einem gewebeverstärkten Laminat verbinden.b) You can connect them with a fabric-reinforced laminate.
3. Die Masse kann man auf ein vorimprägniertes Verstärkungsgewebe, das gegebenenfalls vorgewärmt sein kann, aufschütten und das Ganze durch einen Kalander führen. Dieses Laminat kann man dann zu einem Verbundlager oder Schichtwerkstoff verarbeiten.3. The mass can be applied to a pre-impregnated reinforcement fabric, which is optionally preheated can be, pour it up and run the whole thing through a calender. This laminate can then be processed into a composite bearing or layered material.
45 Volumteile wasserlösliches Phenolformaldehydharz (85 % Feststoffgehalt) wurden in einem Mischer mit drei Armen mit 10 Volumteilen Graphitpulver versehen, dann wurden 10 Volumteile Bleipulver eingebracht und schließlich 35 Volumteile Polytetrafluoräthylen eingeführt. Die Masse wurde auf einem 3,175 mm Sieb abgequetscht, so daß ein trockenes, faseriges Produkt entstand, welches sich je nach dem Anwendungszweck weiter verarbeiten ließ.45 parts by volume of water-soluble phenol-formaldehyde resin (85% solids) were placed in a mixer provided with three arms with 10 parts by volume of graphite powder, then 10 parts by volume of lead powder were introduced and finally 35 parts by volume of polytetrafluoroethylene introduced. The mass was squeezed on a 3.175 mm sieve so that a dry, fibrous product was created, which could be further processed depending on the application.
100 Gewichtsteile flüssiges Polyurethan mit 9 bis 10 % Isocyanatgruppen wurden bei 100° C und einem Druck von 5 mm Hg entgast, dann auf 80° C abgekühlt und 25 Gewichtsteile 4,4'-Methylen-bis(2-chloranilin) — erschmolzen bei 100 bis 105° C — schnell und gründlich untermischt. Das Ganze wurde auf eine Tasse gegossen, auf Raumtemperatur abgekühlt und in einer Kautschukmühle mit 40 Volumprozent Polytetrafluoräthylen durchgearbeitet. Die dabei gebildeten Folien wurden bei 100° C in 15 min und bei einem Preßdruck von etwa 8 bis 16 kg geformt und noch 45 min bei 100° C gehalten.100 parts by weight of liquid polyurethane with 9 to 10% isocyanate groups were at 100 ° C and one Pressure of 5 mm Hg degassed, then cooled to 80 ° C and 25 parts by weight of 4,4'-methylenebis (2-chloroaniline) - melted at 100 to 105 ° C - mixed in quickly and thoroughly. The whole thing was Poured onto a cup, cooled to room temperature and placed in a rubber mill at 40 percent by volume Polytetrafluoroethylene worked through. The resulting films were at 100 ° C in 15 min and molded at a pressure of about 8 to 16 kg and held at 100 ° C. for a further 45 minutes.
