Durch die erfindungsgemäßen Maßnahmen ist es möglich, Formteile, die aus expandierbaren Kunststoffen, wie Polypropylen, Polyethylen und Polystyrol, hergestellt sind, in einfacher und schneller Weise mit einem Oberflächenüberzug versehen werden können, so daß die Formteile an ihrer Außenfläche vielfältige qualitative Beschaffenheiten und/oder dekorative Aussehen erhalten können.The measures according to the invention make it possible to Molded parts made of expandable plastics, such as Polypropylene, polyethylene and polystyrene are manufactured in easier and faster way with a surface coating can be provided so that the molded parts on their Outside surface diverse qualitative textures and / or can get decorative looks.
Ein derartiger Überzug kann gemäß den Merkmalen des Anspruchs 2 bzw. 3 und 10 bzw. 11 durch einfaches Aufsprühen des flüssigen Kunststoffes auf das Formteil oder durch Eintauchen des Formteils in den flüssigen Kunststoff hergestellt werden.Such a coating can according to the features of the claim 2 or 3 and 10 or 11 by simply spraying the liquid plastic on the molded part or by immersion of the molded part in the liquid plastic.
Der Überzug kann dabei relativ dünn oder in einfacher Weise derart ausgestaltet sein, daß er nach Art einer Haut das Formteil ganz oder teilweise überzieht, wie sich dies aus den Merkmalen des Anspruchs 9 bzw. denen des Anspruchs 12 ergibt.The coating can be relatively thin or simple be designed in such a way that it looks like a skin Fully or partially covers the molded part, as is evident from the Features of claim 9 or those of claim 12 results.
Weitere vorteilhafte Ausgestaltungen ergeben sich aus den weiteren Unteransprüchen.Further advantageous configurations result from the further subclaims.
Weitere Einzelheiten der Erfindung sind der folgenden Beschreibung zu entnehmen, in der die Erfindung anhand bevorzugter Ausführungsbeispiele beschrieben und erläutert ist.Further details of the invention are as follows Description can be found in the invention based on preferred embodiments described and explained is.
Für technische Bauteile dienende Formteile werden zunächst aus einem expandierbaren Kunststoff, vorzugsweise aus Polypropylen, Polyethylen oder Polystyrol in bekannter Weise hergestellt. Diese aus dem expandierten Kunststoff hergestellten, fertigen Formteile werden über einen Teil ihrer Oberfläche oder über ihre gesamte Oberfläche mit einem flüssigen Kunststoff dadurch überzogen, daß entweder der flüssige Kunststoff aufgesprüht oder das Formteil in den flüssigen Kunststoff eingetaucht wird. Dabei wird zweckmäßigerweise die Dauer und/oder die Anzahl der Aufsprüh- bzw. Eintauchvorgänge und/oder die Eigenschaften des flüssigen Kunststoffes die Dicke des Überzugs bestimmen, so daß der Überzug auch die Form einer Haut, d. h. eines relativ dicken Überzugs, einnehmen kann. Nach dem Aufbringen des flüssigen Kunststoffes wird das so behandelte Formteil insbesondere durch Wärmebehandlung getrocknet. Danach kann ein weiterer Aufsprüh- bzw. Eintauchvorgang mit anschließender Trocknung erfolgen, usw.Molded parts serving for technical components are initially made an expandable plastic, preferably made of Polypropylene, polyethylene or polystyrene in a known manner produced. This from the expanded plastic Manufactured, finished molded parts are part of their Surface or over their entire surface with one liquid plastic coated in that either the sprayed liquid plastic or the molded part in the liquid plastic is immersed. Doing so expediently the duration and / or the number of spraying or Immersion processes and / or the properties of the liquid Plastic determine the thickness of the coating so that the Plating also the shape of a skin, i.e. H. one relatively thick Coating, can take. After applying the liquid Plastic is the molded part treated in particular dried by heat treatment. After that, another Spraying or dipping process with subsequent drying done, etc.
Der für den Überzug bzw. die Außenhaut verwendete Kunststoff kann als solcher bei Raumtemperatur flüssig sein; es kann aber auch ein Kunststoff Verwendung finden, der erst nach einer bestimmten Wärmebehandlung, d. h. bei höherer Temperatur flüssig wird. Der flüssige Kunststoff kann wie der zur Herstellung des Formteils verwendete expandierbare Kunststoff aus einem Polypropylen, Polyethylen und/oder Polystyrol sein, wobei für Recyclingzwecke es vorteilhaft sein kann, für das Formteil und dessen Überzug bzw. Außenhaut denselben Kunststoff zu verwenden. Was die erreichbare Qualität des Überzugs bzw. der Außenhaut anbetrifft, hat es sich als vorteilhaft herausgestellt, als flüssigen Kunststoff einen synthetischen Kautschuk oder einen solchen Kunststoff zu verwenden, der in reiner Form oder als Mischung mit PU- (Polyurethan-) Anteilen versehen ist.The plastic used for the cover or the outer skin as such, can be liquid at room temperature; but it can also use a plastic that only after a certain heat treatment, d. H. at higher temperature becomes fluid. The liquid plastic can be used as the Production of the molded part used expandable plastic be made of a polypropylene, polyethylene and / or polystyrene, for recycling purposes it may be advantageous for Molding and its cover or outer skin the same To use plastic. As for the achievable quality of the Cover or the outer skin, it has proven to be advantageously exposed as a liquid plastic synthetic rubber or such a plastic use in pure form or as a mixture with PU (Polyurethane) parts is provided.
Je nach für den Überzug bzw. die Außenhaut verwendetem flüssigen Kunststoff kann das Formteil mit einer harten, einer weichen oder einer im Zwischenbereich zwischen hart und weich liegenden Außenhaut versehen sein. Es ist ferner möglich, den flüssigen Kunststoff in nahezu beliebiger Weise einzufärben, so daß sich eine entsprechende designerisch gestaltbare Außenhaut ergeben kann. Eine weitere Möglichkeit besteht darin, flüssige Kunststoffe derart zu verwenden, daß sich ein antistatischer, elektrisch leitfähiger, schwer entflammbarer, wasserundurchlässiger und/oder dgl. Überzug bzw. Außenhaut für das Formteil ergibt, so daß der Einsatzbereich daraus hergestellter technischer Bauteile erheblich vergrößert wird.Depending on what is used for the cover or the outer skin liquid plastic can the molded part with a hard one soft or one in between between hard and soft lying outer skin. It is also possible that to color liquid plastic in almost any way so that there is a corresponding designable Outer skin can result. Another option is there in using liquid plastics in such a way that a antistatic, electrically conductive, flame retardant, water-impermeable and / or the like. Cover or outer skin for the molded part results, so that the area of application from it manufactured technical components is significantly enlarged.
Als Formteile kommen bspw. solche in Frage, die für technische Bauteile, wie Verpackungsecken, Transportbehälter, Einbauteile, Bausteine usw., Verwendung finden.As molded parts, for example, those that are suitable for technical Components such as packaging corners, transport containers, Built-in parts, building blocks etc., are used.
