Description
Die Erfindung betrifft einen Kunststoffkörper mit rela tiv hohem spezifischem Gewicht, bestehend aus einem Kernkörper, der mit einem Metallpulver gefüllt ist und einer auf dem Kernkörper angeordneten Dekorbeschich tung.The invention relates to a plastic body with rela tiv high specific weight, consisting of a Core body filled with a metal powder and a decorative coating arranged on the core body tung.
Ein derartiger Kunststoffkörper ist aus der Druck schrift DE 36 32 095 A1 bekannt, bei dem auf einem bei spielsweise mit Metallpulver gefüllten Kernkörper in einer besonderen Gießform eine hochwertige Oberflächen schicht ohne Metallpulver aufgebracht ist.Such a plastic body is from the print Document DE 36 32 095 A1 known, in which on a for example, core body filled with metal powder a special mold a high quality surface layer is applied without metal powder.
Durch die erforderliche Verwendung von zwei Gießformen ist die Herstellung der Kunststoffkörper relativ auf wendig.Due to the need to use two molds the manufacture of the plastic body is relatively on agile.
Der Erfindung liegt daher die Aufgabe zugrunde, den im Oberbegriff des Anspruchs 1 angegebenen Kunststoffkör per zu verbessern und ein Verfahren zur Herstellung und die Verwendung anzugeben.The invention is therefore based on the object Preamble of claim 1 specified plastic body per improve and a method of manufacturing and to indicate the use.
Diese Aufgaben werden erfindungsgemäß mit den Ansprü chen 1, 3 und 4 gelöst.These tasks are inventively with the claims Chen 1, 3 and 4 solved.
Weitere Ausgestaltungen der Erfindung sind in Anspruch 2 angegeben. Further embodiments of the invention are claimed 2 specified.
Mit der erfindungsgemäßen Ausbildung des Kunststoff körpers wird erreicht, daß die bisher relativ teuren Zinkdruckgußteile durch gewichtsmäßig schwere pulver lackierbare Kunststoffspritzteile ersetzt werden kön nen. Insbesondere können nach der Erfindung die aufwen digen und teuren Zinkdruckgußgriffe von Sanitärarmatu ren durch gewichtsmäßig entsprechende pulverlackierbare Kunststoffgriffstücke ersetzt werden. Durch den hohen Füllgrad des Kernkörpers mit Metallpulver wird darüber hinaus eine erhöhte Warmformbeständigkeit des Kunst stoffs erreicht, so daß auch hohe Einbrenntemperaturen bis 160°C zu keiner Verformung des Spritzteils führen.With the formation of the plastic according to the invention body is achieved that the previously relatively expensive Die-cast zinc parts by weight-heavy powder paintable plastic injection parts can be replaced nen. In particular, according to the invention expensive and expensive zinc die-cast handles from Sanitärarmatu ren by appropriate powder-coated paint Plastic handles are replaced. By the high The degree of filling of the core body with metal powder is above in addition, an increased heat resistance of the art reached so that even high baking temperatures up to 160 ° C do not lead to any deformation of the molded part.
Ein Ausführungsbeispiel der Erfindung ist in Form eines Griffstücks für Sanitärarmaturen in der Zeichnung im Schnitt dargestellt und wird im folgenden näher be schrieben.An embodiment of the invention is in the form of a Handle for sanitary fittings in the drawing in the Section shown and will be closer in the following wrote.
Das topfartige Griffstück 1 ist zunächst als Kernkörper 2 in einer Spritzgießform in einer Spritzgießmaschine hergestellt worden. Als Werkstoff wird hierbei in der Spritzgießmaschine ein Granulat aus Polypropylen mit einer Metallpulverfüllung, z. B. Zinkpulver, eingesetzt, wobei das Granulat durch das Metallpulver etwa ein spezifisches Gewicht von 4,5 g/cm3 aufweist. Der fer tiggestellte Kernkörper 2 wird dann in einer Pulverbe schichtungsanlage eingebracht und hier bei einem elek trischen Spannungsbereich von etwa 20 bis 80 kV mit einer Dekorbeschichtung 3 aus Pulverlack versehen. Die Füllung des Kernkörpers 2 mit Metallpulver wird in dem vorstehend aufgeführten Spannungsbereich elektrisch leitend, so daß nunmehr auch Kunststoffe, die an sich für eine Pulverlackierung nicht geeignet sind, nach diesem Verfahren beschichtet werden können. Im Anschluß an die Pulverbeschichtung kann dann der erforderliche Einbrennvorgang zur Erzeugung der dauerhaft festen Dekorbeschichtung 3 auf dem Kernkörper 2 vorgenommen werden. Durch den hohen Füllgrad mit Metallpulver ist darüber hinaus der Kernkörper 2 erhöht warmformbestän dig, so daß der Einbrennvorgang bei Temperaturen bis zu 160°C durchgeführt werden kann, ohne daß Verformungen des Kernkörpers 2 auftreten.The pot-like handle 1 was first produced as a core body 2 in an injection mold in an injection molding machine. The material used here in the injection molding machine is a granulate made of polypropylene with a metal powder filling, e.g. As zinc powder, used, the granules having about a specific weight of 4.5 g / cm 3 by the metal powder. The finished core body 2 is then introduced into a powder coating system and is provided here with a decorative coating 3 of powder coating at an electrical voltage range of approximately 20 to 80 kV. The filling of the core body 2 with metal powder becomes electrically conductive in the voltage range mentioned above, so that plastics which are not suitable per se for powder coating can now also be coated using this method. Following the powder coating, the required baking process for producing the permanently solid decorative coating 3 can then be carried out on the core body 2 . Due to the high degree of filling with metal powder, the core body 2 is also increased heat-resistant dig, so that the baking process can be carried out at temperatures up to 160 ° C without deformation of the core body 2 occur.
Selbstverständlich kann die Erfindung auch für andere Kunststoffkörper, z. B. Abdeckrosetten für Sanitärarma turen oder auch komplette Armaturenkörper, eingesetzt werden.Of course, the invention can also be used by others Plastic body, e.g. B. Cover rosettes for sanitary ware tures or complete fitting bodies become.
