Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung eines aus mehreren Komponenten bestehenden Kunststoff-Bauteils gemäß den Oberbegriffen der Ansprüche 1 bzw. 6.The The present invention relates to a method and an apparatus for producing a multi-component plastic component according to the preambles the claims 1 or 6.
Es ist bekannt, Kunststoffteile aus mehreren Komponenten herzustellen, wobei beispielsweise eine Komponente ein Thermoplast-Material und eine Komponente ein Polyurethan-Material sein kann. Dazu kann beispielsweise ein Thermoplast-Träger in einem Spritzgießverfahren hergestellt werden. Der so hergestellte Thermoplast-Träger kann dann nachfolgend mit einem PU-Material beschichtet werden. Diese Beschichtung ist durch Bekleben oder durch einfaches Überfluten des Träger in einer Kavität möglich.It is known to produce plastic parts from several components, for example, a component is a thermoplastic material and a component may be a polyurethane material. This can for example a thermoplastic carrier in an injection molding process getting produced. The thermoplastic carrier produced in this way can then be subsequently coated with a PU material. These Coating is by gluing or simply flooding of the carrier in a cavity possible.
Bislang werden für die Beschichtung von thermoplastischen Gegenständen insbesondere aromatische, geschäumte Polyurethan-Materialien verwendet. Aromatische Polyurethan-Systeme weisen in der Regel aber nur eine geringe UV-Stabilität auf. Durch Zugabe von UV-Stabilisatoren ist es gelungen, dunkle Farbtöne von geschäumten, aromatischen PUR-Systemen mit einer ausreichend guten UV-Stabilität herzustellen. Für helle Farbtöne ist dies jedoch nicht gelungen.So far be for the coating of thermoplastic objects, in particular aromatic, foamed Polyurethane materials used. Aromatic polyurethane systems but usually have only a low UV stability. By Addition of UV stabilizers has succeeded in producing dark shades of foamed, aromatic PUR systems produce with a sufficiently good UV stability. For bright colors However, this has not succeeded.
Auf der anderen Seite gibt es sogenannte aliphatische Polyurethan-Materialien oder -systeme, welche die geforderte UV-Stabilität besitzen. Aliphatische Polyurethan-Systeme sind kompakte Systeme die nicht aufgeschäumt werden.On On the other hand, there are so-called aliphatic polyurethane materials or systems which have the required UV stability. Aliphatic polyurethane systems are compact Systems that are not foamed become.
Aufgabe der vorliegenden Erfindung ist es, ein aus mehreren Komponenten bestehendes Kunststoffteil herzustellen, das bei gewünschter Haptik ausreichend UV-stabil ist und bezüglich des Farbdesigns jede Freiheit gestattet.task The present invention is one of several components make existing plastic part, the desired Haptic sufficiently UV-stable is and re the color design allows any freedom.
Diese Aufgabe wird verfahrensmäßig durch die im Anspruch 1 angegebenen Merkmale und vorrichtungsmäßig durch die im Anspruch 6 angegebenen Merkmale gelöst.These Task is procedurally by the Characterized in claim 1 features and device by device solved specified in claim 6 features.
Demgemäß ist ein Gedanke der vorliegenden Erfindung darin zu sehen, einen Grundkörper sowohl mit einem aromatischen wie auch mit aliphatischen Polyurethan-Material zu beschichten. Die Beschichtungen können nacheinander oder aber auch gleichzeitig ausgeführt werden. Letzteres natürlich nur insofern sich die beiden Polyurethan-Materialien auf dem Grundkörper nicht überlappen. Dabei wird das aliphatische Polyurethan-Material insbesondere für helle Farbtöne verwendet, das aromatische Polyurethan-Material für einen dunklen Farbton. Auch können zwei oder mehrere aromatische Polyurethan-Materialien wie auch zwei oder mehrere aliphatische Polyurethan-Materialien, beispielsweise verschiedene Polyurethan-Materialien mit unterschiedlichen Farbtönen verwendet werden.Accordingly, a It is an object of the present invention to provide a base body both to coat with an aromatic as well as with aliphatic polyurethane material. The coatings can be executed sequentially or simultaneously. The latter, of course, only insofar as the two polyurethane materials do not overlap on the base body. The aliphatic polyurethane material is especially for bright colors used, the aromatic polyurethane material for a dark shade. Also can two or more aromatic polyurethane materials as well as two or more aliphatic polyurethane materials, for example used different polyurethane materials with different shades become.
Beim Betrieb einer Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens müssen zumindest zwei Polyurethan-Einheiten zum Aufbringen der aromatischen bzw. aliphatischen Polyurethan-Materialien verwendet werden. Dabei können die verschiedenen Polyurethan-Materialien mit getrennten Mischköpfen oder auch mit einem gemeinsamen Mischkopf, der sukzessive mit den verschiedenen Polyurethan-Materialien betrieben wird, verbunden oder verbindbar sein. In einer Schließeinheit zur Aufnahme eines Werkzeugs, in dem die Kavität oder die Kavitäten vorgesehen sind, können auch Wendeplatten, Schiebetisch, Drehtisch und Indexeinrichtungen zur Umsetzung der Zwischenprodukte verwendet werden.At the Operation of a device for carrying out the method according to the invention at least have to two polyurethane units for applying the aromatic or aliphatic polyurethane materials are used. The can different polyurethane materials with separate mixing heads or also with a common mixing head, successively with the different ones Polyurethane materials operated, connected or connectable. In a closing unit for Recording a tool in which the cavity or cavities provided are, can also inserts, sliding table, turntable and index devices be used for the implementation of the intermediates.

Mit der vorliegenden Erfindung ist es durch geschickte Kombination der jeweiligen Polyurethan-Systeme (aromatisch oder aliphatisch) möglich, komplexe Mehrfarben-Bauteile in einem kompakten Verfahren herzustellen. Es sind keine weiteren zeit- und kostenintensiven Nachbehandlungen der Formteile notwendig. So kann auf eine Aufbringung einer Schutzlackschicht für eine notwendige UV-Stabilität verzichtet werden.With the present invention, it is possible by skillful combination of the respective polyurethane systems (aromatic or aliphatic), complex multicolor components in a compact Process to produce. There are no more time-consuming and costly post-treatments of the moldings necessary. So can be dispensed with an application of a protective lacquer layer for a necessary UV stability.
