Description

Die Erfindung betrifft den im Oberbegriff des Patentan­ spruches 1 definierten Gegenstand sowie ein Verfahren zu seiner Herstellung.The invention relates to that in the preamble of the patent Proof 1 defined subject and a method for its manufacture.

Fenster- und Türprofile werden heute in großem Umfange aus Kunststoffmaterial im Extrusionsverfahren herge­ stellt, wobei sich unter anderem insbesondere Kunst­ stoffmaterialien auf der Basis von Polyvinylverbindun­ gen bewährt haben. So ist es seit langem bekannt, Poly­ mere auf der Basis von Vinylchlorid zu Profilen zu ex­ trudieren, um Profile verfügbar zu machen, die im Hin­ blick auf die spätere Verglasung und den Einbau in die Fenster- und Türrahmen komplizierte Formen aufweisen können, wie dies beispielsweise in Fig. 1 dargestellt ist.Window and door profiles are now widely produced from plastic material in the extrusion process, with plastic materials based on polyvinyl compounds in particular having proven themselves. So it has long been known to extrude poly mers based on vinyl chloride to extrusions to make available profiles that may have complicated shapes with a view to the subsequent glazing and installation in the window and door frames, such as this is shown for example in Fig. 1.

Bei der Herstellung von Profilen für Fenster und Türen wird im allgemeinen von einem pulverförmigen Polyvinyl­ chlorid ausgegangen, dem trocken weitere Komponenten beigemischt werden, die nicht nur die Verarbeitung des Kunststoffmaterials erleichtern, sondern auch von erheb­ licher Bedeutung sind sowohl für die Farbgebung des Kunststoffmaterials als auch für die mechanischen Eigen­ schaften des Werkstoffes beim späteren Einsatz der ex­ trudierten Formteile. Hierbei handelt es sich neben Farbpigmenten, beispielsweise Titandioxid für weißes Preßmaterial, um zum Teil unterschiedliche Füllstoffe, wie beispielsweise Kreide, die einerseits dazu dienen, die Stoffkosten zu erniedrigen, während andererseits Füllstoffe zusätzlich Verwendung finden, um die Schlag­ zähigkeit der Profile zu erhöhen, nämlich sogenannte Modifier. Darüber hinaus ist es im allgemeinen erfor­ derlich, dem Preßmaterial vor seiner Verarbeitung im Extrusionsverfahren innere und äußere Gleitmittel zuzu­ geben, mit denen die Friktion beim Extrudieren herabge­ setzt wird. Von entscheidender Bedeutung und praktisch unverzichtbar im Preßmaterial sind aber Stabilisatoren, die nicht nur die Wärmebeständigkeit des Preßmaterials während dem Extrusionsverfahren gewährleisten, sondern auch mit dazu beitragen, daß die extrudierten Profile bei ihrem späteren Einsatz eine über viele Jahre gesi­ cherte Belichtungs- und Bewitterungsbeständigkeit auf­ weisen. In the production of profiles for windows and doors is generally from a powdered polyvinyl chloride out, the dry other components to be added, not only the processing of the Lighten plastic material, but also of considerable Licher importance are both for the coloring of the Plastic material as well as for the mechanical own the material when later using the ex molded parts. This is alongside Color pigments, for example titanium dioxide for white Molding material to fill different fillers, such as chalk, which on the one hand serve to to lower the fabric cost while on the other hand Fillers are also used to beat the blow to increase the toughness of the profiles, namely so-called Modifier. In addition, it is generally required derlich, the press material before its processing in Extrusion process added internal and external lubricants with which the friction is reduced during extrusion is set. Crucial and practical but stabilizers are indispensable in the press material, which is not just the heat resistance of the press material ensure during the extrusion process, but also contribute to the extruded profiles when used later, it was used for many years improved exposure to light and weather point.  

Bei der Verarbeitung der geschilderten Kunststoffgemi­ sche im Extrusionsverfahren kommt es leider während der verschiedenen Verfahrensschritte häufig zu einer Min­ derung der Wirkung der Stabilisatoren und damit gleich­ zeitig zu einer geringeren Stabilität der Preßmassen, die sich beim späteren endgültigen Einsatz der Profile in unerwünschter Weise dadurch bemerkbar machen, daß die Belichtungsbeständigkeit und auch die Bewitterungs­ beständigkeit herabgesetzt worden sind. Außerdem fallen beim Hersteller der Profile und bei der späteren Weiter­ verarbeitung bei den Fensterherstellern in nicht uner­ heblichem Umfang Abfälle an Extrusionsmaterial an, die wegen der bei der Produktion nicht zu vernachlässigen­ den Werkstoffkosten mit einkalkuliert werden müssen und die Kosten der Profile steigern.When processing the described plastic mixture The extrusion process unfortunately occurs during the different process steps often to a min change the effect of the stabilizers and thus the same in time to a lower stability of the molding compounds, the later final use of the profiles make it noticeably noticeable in that the exposure resistance and also the weathering resistance has been reduced. Also fall at the manufacturer of the profiles and later on processing at the window manufacturers in not uncommon considerable waste of extrusion material, the not to be neglected in the production the material costs must be taken into account and increase the cost of the profiles.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren verfügbar zu machen, mit dem es gelingt, den Einsatz insbesondere der sehr kostenaufwendigen Stabilisatoren zu reduzieren, indem die weniger stabilen Vorstufen des Extrusionsverfahrens und auch die Abfälle der Endher­ steller der Profile einer sinnvollen Wiederverwertung zugeführt und damit gleichzeitig die Stoffkosten herab­ gesetzt werden können.The invention has for its object a method to make available, with which it succeeds in deploying especially the very expensive stabilizers to reduce by the less stable precursors of the Extrusion process and also the wastes of the endher of the profiles of a meaningful recycling fed and at the same time the material costs down can be placed.

Die Lösung dieser Aufgabe ist der im kennzeichnenden Teil des Hauptanspruches wiedergegebene Gegenstand.The solution to this problem is the characteristic one Part reproduced in the main claim.

Erfindungsgemäß hat es sich besonders bewährt, für die Profilinnenbereiche ein Kunststoffmaterial vorzusehen, das einen geringeren Stabilisatoranteil enthält, um auf diese Weise die Rohstoffkosten der Gesamtprofile zu reduzieren. Hierbei kann es sich entweder um ein Mate­ rial handeln, das aus bereits gebrauchten, also schon im Einsatz gewesenen Fenster-/ oder Türprofilen durch Zerkleinern und Regenerieren erhalten wird und bei dem infolge dieser Arbeitsgänge die Wirksamkeit der Stabi­ lisatoren reduziert worden ist. Es kann sich aber auch um ein Material handeln, das als Abfall beim Extrudie­ ren der Profile und beim Konfektionieren anfällt und somit erfindungsgemäß seiner Wiederverwendung zugeführt wird, um auch auf diese Weise die Rohstoffkosten zu senken.According to the invention, it has proven particularly useful for To provide a plastic material for the interior of the profile, which contains a lower proportion of stabilizer to this way the raw material costs of the overall profiles to reduce. This can either be a mate  act rial, that from already used, so already used window or door profiles Shredding and regeneration is obtained and in the as a result of these operations, the effectiveness of the stabilizers lisators has been reduced. But it can also act as a material that is wasted in extrusion the profiles and when assembling and thus fed to its reuse according to the invention is going to increase raw material costs in this way too reduce.

Die durch Coextrusion von Frischmaterial für die Profil­ außenbereiche einerseits und dem hier kurz Regeneratma­ terial geringer Licht- und Bewitterungsstabilität ge­ nannten Kunststoffmaterial für die Profilinnenbereiche werden Fenster- und/oder Türprofile gemäß der Erfindung erhalten, die sich gegenüber solchen aus reinem Frisch­ material bei Schlagbiegeversuchen hinsichtlich ihrer Schlag- und Kerbschlagzähigkeit im Außenprofilbereich nicht unterscheiden und sich auch bei Versuchen zur Ermittlung der Lichtbeständigkeit und Bewitterungsbe­ ständigkeit im Außenprofilbereich genau so verhalten wie aus reinem Frischmaterial gewonnene Fenster- und /oder Türprofile. Diese Profile gemäß der Erfindung besitzen darüber hinaus auch die in den Normen für Fen­ ster- und Türprofile festgelegte Stoßfestigkeit. Die ausgezeichneten Werte bezüglich der mechanischen Eigen­ schaften und der im Einsatz besonders wichtigen Bestän­ digkeit gegen Licht- und Wettereinflüsse bleiben bei den Profilen gemäß der Erfindung auch dann voll erhal­ ten, wenn zusätzlich Profilaußenschichten aus Meth­ acrylatpolymeren Verwendung finden, also beispielsweise Außenschichten aus Homo- oder Copolymerisaten des Meth­ acrylsäuremethylesters. The coextrusion of fresh material for the profile outside areas on the one hand and the here briefly Regeneratma low light and weathering stability called plastic material for the profile interior become window and / or door profiles according to the invention get that against those of pure fresh material in impact bending tests with regard to their Impact and notched impact strength in the outer profile area do not differ and also differ in attempts at Determination of light resistance and weathering The behavior in the outer profile area is exactly the same like windows and windows made from pure fresh material / or door profiles. These profiles according to the invention also have those in the norms for fen shock and door profiles defined impact resistance. The excellent mechanical properties and the stocks that are particularly important in use Resistance to light and weather influences remains then get the profiles according to the invention fully ten if additional profile outer layers made of meth find acrylate polymers, for example Outer layers made of homo- or copolymers of meth acrylic acid methyl ester.  

Im praktischen Einsatz der Profile gemäß der Erfindung hat sich gezeigt, daß es von Vorteil ist, wenn der Ge­ wichtsanteil der Profilinnenbereiche etwa zwei Drittel des Gesamtprofiles ausmachen; denn hierbei werden die besten Gebrauchswerte erreicht bei einem wesentlich geringeren Verbrauch an Frischmaterial.In practical use of the profiles according to the invention has shown that it is advantageous if the Ge Weight share of the profile interior areas about two thirds make up the overall profile; because here the best use values achieved with one lower consumption of fresh material.

Bezüglich der Farbgebung des Außen- bzw. Innenbereiches der Profile gemäß der Erfindung sind beliebige Kombina­ tionen möglich, indem beispielsweise ein hellfarbiges Frischmaterial für den Außenbereich mit einem dunkel­ farbigen Regeneratmaterial für den Innenbereich der Profile coextrudiert wird. Gleichermaßen kann ein dun­ kelfarbiges Frischmaterial für den Außenbereich der Profile mit hellem und/oder farbigem Regeneratmaterial für den Innenbereich der Profile miteinander kombiniert werden. Von erfindungswesentlicher Bedeutung ist ledig­ lich die Anordnung von Frischmaterial unabhängig von der Farbgebung in den Außenbereichen der Profile, also in den Bereichen, die den mechanischen und atmosphäri­ schen Einflüssen beim späteren Einsatz ausgesetzt sind; denn auf diese Weise ist es möglich, einerseits die hohen Kosten der Fenster- und/oder Türprofile in erheb­ lichem Umfange zu reduzieren, während andererseits Fen­ ster- und/oder Türprofile hergestellt werden können, die den festgelegten Normen trotz der Einsparung von Materialkosten in vollem Umfange entsprechen.Regarding the color of the exterior or interior the profiles according to the invention are any combination tion possible by, for example, a light colored Fresh material for outdoors with a dark colored regenerated material for the interior of the Profile is coextruded. Similarly, a dun skin-colored fresh material for the exterior of the Profiles with light and / or colored regenerated material combined for the interior of the profiles will. Of single importance is single Lich the arrangement of fresh material regardless of the coloring in the outer areas of the profiles, so in the areas that affect the mechanical and atmospheric exposed to influences during later use; because in this way it is possible on the one hand the high cost of window and / or door profiles in considerable to reduce the scope, while Fen star and / or door profiles can be produced, which meet the established standards despite the savings of Correspond fully to material costs.

In den Zeichnungen sind als Beispiele Profile jeweils im Schnitt dargestellt, wobei Fig. 1 ein aus einheitli­ chem Frischmaterial im Extrusionsverfahren gewonnenes Profil des Standes der Technik wiedergibt. Fig. 2 stellt dagegen ein durch Coextrusion erhaltenes Profil gemäß der Erfindung dar, dessen Innenbereiche 2 aus weniger stabilem Regeneratmaterial eingeschlossen werden von den den mechanischen und atmosphärischen Einflüssen ausgesetzten Außenbereichen 1 aus Frischmaterial hoher Stabilität.In the drawings, profiles are shown in section as examples, with FIG. 1 showing a profile of the prior art obtained from uniform fresh material in the extrusion process. Fig. 2, however, provides a product obtained by co-extrusion profile according to the invention, the inner areas are included 2 from less stable high reclaim material from the exposed to the mechanical and atmospheric influences outer regions 1 of fresh material stability.
