Description

Material zur Herstellung eines wartungsfreien - gleitwerkstoff ■ - Material for the production of a maintenance-free sliding material ■ -

Die Erfindung bezieht sich auf ein Materie! zur Herstellung eines wartungsfreien Gleitwerkstoffs auf der Basis eines wirbelsintern fähigen Duroplastpulvers, in dessen einzelnen Teilchen feinkörniges Polytetraüuoräthylen als Füllstoff homogen verteilt enthalten ist nach Patent (Patentanmeldung P 21 36 601.8-43).The invention relates to a matter! to make a maintenance-free sliding material based on a whirl-sintering thermoset powder, in its individual particles fine-grained Polytetraüuoräthylen contained homogeneously distributed as a filler is according to patent (patent application P 21 36 601.8-43).

Das in dem Hauptpatent (PatentanmeldungThe one in the main patent (patent application

P 21 36 601.3*43) behandelte Material zur Herstellung eines wartungsfreien Gleitwerkstoffs auf der Basis eines Duroplasts mit eingelagertem feinkörnigem Polytetrafluorethylen hat den Vorteil, daß mit diesem Material beliebig dicke Gleitschichten in einem einzigen Verfahrensgang hergestellt werden können und eine nach* träglieh spanende Bearbeitung dieser Gleitschicht«» nicht mehr erforderlich ist. Ferner entstehen bei der Verarbeitung dieses Materials zu Verbund- oder Massivgleitwerkstoffen keine schädlichen Lösungsmitteldampf β. Da ferner 4m» Polytetrafluorethylen in den einzelnen Teilchen des Duroplastpulvers verteilt ist und eine Bat·* mischung bei der Verarbeitung des Materials zu einem Gleitwerkstoff nicht stattfinden kann* besitzt der aus diesem Material hergestellte Gleitwerkstoff einen sehr gleichmässigen Aufbau und weist somit unabhängig von seiner Verschleißtief· gleichbleibendeP 21 36 601.3 * 43) treated material for the production of a maintenance-free sliding material based on a thermosetting plastic with embedded fine-grained polytetrafluoroethylene has the advantage that sliding layers of any thickness can be produced with this material in a single process and a subsequent machining of this sliding layer «» Is no longer required. Furthermore, when processing this material into composite or solid sliding materials, no harmful solvent vapor β is generated. Furthermore, since 4m » polytetrafluoroethylene is distributed in the individual particles of the thermoset powder and a bat consistent

Gleiteigenschaften auf.· Die mit diesem Material hergestellten Gleitecfalchten haben aufgrund der homogenen Verteilung des sehr fein· körnigen Polytetrafluoräthylen nur eine sehr geringe Sprödigkeit, so dafl eine mechanische Verformung des Gleitlagers ohne Zerstörung der Bindung zwischen Gleitwerlutoff und dem metalliechen StQtzkörper eines Verbundwerkstoffes erfolgen kann.The sliding braids made with this material Due to the homogeneous distribution of the very fine-grained polytetrafluoroethylene, they only have a very low degree of brittleness, so that a mechanical deformation of the plain bearing without destruction the bond between Gleitwerlutoff and the metallic support body of a composite material can take place.

Es wurde nun gefunden, daß die Verschleißfestigkeit und Belastbarkeit des aus diesem Material hergestellten Gleitwerkstoff es gesteigert und damit die Lsjufeigenschaften verbessert werden können, wenn erfindungsgamfiß 5 bis 20 Vol. % vorzugsweise 5 bis 10 Vol.% des Polytetrafluorftthylen durch Thermoplaste ersetzt sind.It has now been found that the wear resistance and resilience the sliding material made from this material can be increased and the slip properties can be improved, if according to the invention 5 to 20% by volume, preferably 5 to 10% by volume of Polytetrafluorftthylen are replaced by thermoplastics.

Als Thermoplaste werden insbesondere Polyolefine, vorzugsweise Polyäthylen und/oder Polyamide, vorzugsweise Polyamid 11 bzw. Polyamid 12 verwendet.Polyolefins, in particular, are preferred as thermoplastics Polyethylene and / or polyamides, preferably polyamide 11 or polyamide 12, are used.

In Anwendungsfällen,bei denen mit einer vergleichsweise geringen Erwärmung des Gleitlagers zu rechnen ist, kann das Polytetrafluoräthylen vollständig durch Thermoplaste ersetzt sein.In applications where a comparatively low If the plain bearing is expected to heat up, the polytetrafluoroethylene can be completely replaced by thermoplastics.

Gegebenenfalle kann ein derartiges Material noch 0,5 bis 10 Vol.% eine« Schmier stoffes, beispielsweise Mineralöl, Syntheseöle SiIikonöl, Schmierfett oder dgl. homogen verteilt enthalten.If necessary, such a material can contain 0.5 to 10% by volume. a «lubricant, for example mineral oil, synthetic oils, silicone oil, Containing grease or the like distributed homogeneously.
