nissen angcpaßtei Starke aufgebracht wobei ebenfalls sowohl das Flammspritz- als auch das Wirbelsmterverfahren angewandt werden kann Da die Polyamidzwischenschicht infolge der Warmevorbehandlung des Werkstucks noch in einer zähflüssigen Konsistenz vorliegt, verschmilzt die nachfolgend aufgetragene Polyathylenschicht einwandfrei mit der Zwischen schicht und ist praktisch von dieser nicht mehr zu trennennissen angcpaßtei strength applied also being Both the flame spray and the vortex method can be used as the polyamide intermediate layer due to the pre-heat treatment of the workpiece, it still has a viscous consistency is present, the subsequently applied polyethylene layer fuses perfectly with the intermediate layer and can practically no longer be separated from it

Verfahren zum Verbessern der Haftfestigkeit von flammgespritzten oder wirbelgesinterten Poly athylen-Uberzugen auf metallischen Unterlagen, wie ζ B Eisen, durch eine organische Zwischen schicht dadurch gekennzeichnet, daß die Unterlage vor dem Auftragen des Polyäthylens mit einem Polykondensationsprodukt aus ω Ammoundecansaure die über Undecylensaure aus Ricmusol her gestellt worden ist überzogen wirdProcess for improving the bond strength of flame-sprayed or fluid-sintered poly ethylene coatings on metallic substrates, such as ζ B iron, through an organic intermediate layer characterized in that the base prior to the application of the polyethylene with a Polycondensation product from ω ammoundecanoic acid which has been made from ricmusol via undecylenic acid is coated

Claims (1)

Das Überziehen von insbesondere großflächigen Werkstucken, Maschinenteilen usw mit Polyäthylen, sei es im Flammspritz oder Wirbelsinterverfahren, scheitert in der Regel daran, daß die Polyathylen-Uber7uge infolge Temperaturschwankungen, wie beispielsweise beim Abkühlen der bespritzten Flachen, sich stellenweise vom Untergrund abheben oder zu mindest nicht fest auf demselben (ζ Β Eisen) haften Auch bestimmte Verschleiß oder Fliehkraftbeanspiuchungen können Abloseerscheinungen zur Folge habenCovering especially large areas Workpieces, machine parts, etc. with polyethylene, be it in the flame spray or fluidized bed process, usually fails because the polyethylene cover due to temperature fluctuations, such as when the sprayed surfaces cool down, stand out from the ground or close in places at least not stick firmly to the same (ζ Β iron) Also certain wear and tear or centrifugal forces can result in signs of detachment Es wurde nun gefunden, daß die Haftfestigkeit der Polyathylen-Überzuge dadurch wesentlich verbessert wird, daß auf die metallische Unterlage zunächst das bekannte Poljkondensationsprodukt aus ω Aminoun decansaure, die über Undecylensaure aus Ricmusol hergestellt worden ist, in dunner Schicht flamm gespritzt oder wirbelgesintert wird Von allen be kannten Polyamiden ist dieses über die Undecylen saure aus Ricmusol hergestellte Kondensationsprodukt ganz besonders als haftfeste Zwischenschicht geeignet Andere, insbesondere in Deutschland hergestellte Polyamidprodukte, eignen sich nicht als Zwischenschicht in Verbindung mit einem Polyäthylen Überzug, da dieser hier nicht hinreichend haftet, so daß die Polyathylenschicht nach Erkalten des Werkstuckes verhältnismäßig leicht von derartigen Polyamidzwischenschichten abgetrennt werden kann wahrend die beanspruchte Polyamidschicht ausgezeichnete Haftung auf einer Eisenrundflache aufweistIt has now been found that the adhesive strength of the polyethylene coatings is significantly improved by first spraying the known polycondensation product from ω Aminoun decans aure , which has been produced from ricmusol via undecylenic acid, in a thin layer or by fluidizing it onto the metal base All known polyamides, this condensation product produced from ricmusol via the undecylenic acid is particularly suitable as an adhesive intermediate layer After the workpiece has cooled down, the polyethylene layer can be separated relatively easily from such intermediate polyamide layers, while the claimed polyamide layer exhibits excellent adhesion to a circular iron surface AusfuhrungsbeispielExemplary embodiment Die zu überziehenden Teile werden zuerst entweder durch Quarz oder Metallkies einwandfrei metallisch blank aufgerauht und dann je nach Starke des Materials auf etwa 200 bis 500° C in Abhängigkeit von der_Warmekapazitat des zu überziehenden Werkstuckes erhitzt, wobei auch Warmeverluste auf dem Weg von der Erhitzungsstelle zur Auftragsvorrichtung berücksichtigt werden müssen Im Anschluß daran wird entweder durch eine Spritzpistole oder im Wirbelsinterverfahren eine dünne Schicht von 0 05 bis 0,2 mm Starke eines Polykondensationsproduktes aus ω Ammoundecansaure, die über Undecylensaure aus Ricmusol hergestellt wurde, aufgetragen und hier aui ein Polyathylenuberzug in den jeweiligen Bedurf Verfahren zum Verbessern
der Haftfestigkeit von flammgespritzen oder wirbelgesinterten Polyathylen-The parts to be coated are first roughened with either quartz or metal pebbles to a perfectly bright metal and then, depending on the thickness of the material, heated to around 200 to 500 ° C depending on the warm capacity of the workpiece to be coated, with heat losses on the way from the heating point to the application device must then be taken into account, either with a spray gun or in the fluidized-bed process, a thin layer of 0.05 to 0.2 mm thick of a polycondensation product made from ω ammoundecanoic acid, which was produced from ricmusol using undecylenic acid, is applied, and a polyethylene coating is added as required Method of improvement
