Abstract
Description
Derartige Profile werden u. a. für vielfältige technische Zwecke gebraucht, wo es im Wettbewerb auf leichtes Gewicht, aber gute Bruchfestigkeit, Witterungsbeständigkeit, die optische Erscheinung und wegen des Ver gleichs mit Profilen aus anderen Materialien auch auf die Herstellungskosten, insgesamt also auf eine Kombination positiver Eigenschaften ankommt, die sich normalerweise gegenseitig ausschließen. Anwendung finden solche Profile z. B. als Bordbretter und Beläge für den Gerüstbau, tragende und abdeckende Profile für den Hochbau, Beläge für Pritschen und Anhänger im Fahrzeugbau sowie in der Möbelindustrie und im Maschinen- und Anlagenbau.Such profiles are u. a. used for a variety of technical purposes where it competes on light weight Weight, but good breaking strength, weather resistance, the visual appearance and because of the ver at the same time with profiles made of other materials also on the manufacturing costs, in total on one Combination of positive traits that are usually mutually exclusive. application find such profiles z. B. as toe boards and coverings for scaffolding, load-bearing and covering Profiles for building construction, coverings for platforms and trailers in vehicle construction as well as in the furniture industry and in mechanical and plant engineering.
Es ist bekannt, Profile aus einem Gemisch aus Kunststoff mit einem hohen Anteil von über 80% Holzspänen herzustellen.It is known to profiles from a mixture of plastic with a high proportion of over 80% wood chips to manufacture.
Diese Profile sind wegen der niedrigen Materialkosten kostengünstig, haben aber auch nur eine geringe Bruchfestigkeit und ein minderwertiges Aussehen. Für höhere Anforderungen wird auf extrudierte Profile zu rückgegriffen, die überwiegend aus Kunststoff mit einem kleineren Anteil Füllstoffen bestehen. Diese Profile sind jedoch schwerer und infolge der Kosten der Ausgangsmaterialien teurer.These profiles are inexpensive because of the low material costs, but they are also low Breaking strength and an inferior appearance. For higher requirements, extruded profiles are used recourse, which consist mainly of plastic with a smaller proportion of fillers. These profiles however, are heavier and more expensive due to the cost of the raw materials.
Durch eine Bewehrungseinlage, zur Erhöhung der Stabilität, werden diese Profile schwerer und teurer mit der Folge, daß ihre Verwendung beschränkt bleibt.A reinforcement insert to increase stability makes these profiles heavier and more expensive with the As a result, their use remains limited.
Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Profil so zu schaffen bzw. dahingehend weiterzubilden, daß hohe Gebrauchswerteigenschaften, eine Vielzahl von Anwendungsvariationen einerseits und ökonomischen und ökologischen Aspekten in höchstem Maß andererseits, miteinander vereint sind.The invention has for its object to provide a generic profile or to that effect to further develop that high utility value properties, a variety of application variations on the one hand and economic and ecological aspects on the other hand, are united to the highest degree.
Diese Aufgabe wird erfindungsgemäß, ausgehend von einem gattungsgemäßen extrudierten Profil, dadurch gelöst, daß der thermoplastisch verarbeitbare Werkstoff ein Gemisch fasriger Naturstoffe und thermoplas tischer Kunststoffe, erforderlichenfalls mit kunststoffspezifischen Hilfsstoffen, wie Gleitmitteln, Stabilisatoren, Weichmachern u. a., versehen ist und in diesem, zum Profil extrudierten oder pultrudierten Gemisch, eine Bewehrungseinlage eingebettet ist und die Endkonfektionierung mittels Transferdruck-Kaschierung erfolgt. Das Gemisch, dessen in hohem Masseanteil enthaltene Komponente fasriger Naturstoffe, die im Gegensatz zu dem Anteil thermoplastischer Kunststoffe, im Herstellungsprozeß des Profiles nicht plastifiziert wird, er übrigt nicht nur weitgehend eine herkömmliche Vakuumkalibrierung. Vielmehr eröffnet es die Möglichkeit, das Profil unmittelbar, in noch plastisch-formbarem Zustand in Formen, Kavitäten u. ä., bis zur Endform gebung, bei Wärmeabgabe, zu formen, z. B. zu Bögen, Eck-Stücken u. ä.. In dieser Eigenschaft bzw. Phase des plastisch formbaren Zustandes des Gemisches bzw. des Profiles erkennt der Fachmann die Option, die Armierung, eine Bewehrung unmittelbar im Anschluß an die Extrusion am bzw. im Profil zu positionieren. Auch die Ausbildung des Profiles, abgelängt zu einer Planke oder Bohle z. B., mit Vorkehrungen für das Koppeln von Planken zum Zweck des Gebrauches, der Anwendung als Laufbohlen z. B., ist in der noch plas tischen Phase vorteilhaft möglich. Es sei auch darauf verwiesen, daß es unproblematisch ist, die Zeitspanne der plastischen Formbarkeit des Profiles zeitlich zu steuern, z. B. zu verlängern, um z. B. Konfektionierungs maßnahmen an selbigem vorzunehmen.This object is achieved according to the invention, based on an extruded profile of the generic type solved that the thermoplastically processable material is a mixture of fibrous natural materials and thermoplas plastic materials, if necessary with plastic-specific additives such as lubricants, stabilizers, Plasticizers and a., is provided and in this, extruded or pultruded mixture, a Reinforcement insert is embedded and the final assembly takes place by means of transfer printing lamination. The mixture, whose high mass component of fibrous natural substances, in contrast to the proportion of thermoplastics, is not plasticized in the manufacturing process of the profile, he not only largely remains a conventional vacuum calibration. Rather, it opens up the possibility the profile immediately, in a still plastically formable state in molds, cavities and. Ä., to the final shape giving, when emitting heat, to shape, e.g. B. to arches, corner pieces u. Ä .. In this property or phase of the plastically mouldable state of the mixture or of the profile, the person skilled in the art recognizes the option that Reinforcement to position reinforcement immediately after extrusion on or in the profile. The formation of the profile, cut to a plank or screed z. B., with arrangements for that Coupling of planks for the purpose of use, the application as planks z. B., is still plas table phase advantageously possible. It should also be noted that the time period is not a problem Timing the plastic formability of the profile, e.g. B. to extend z. B. Packaging to take measures on the same.
Mittels der als Transferdruck ausgeführten Kaschierung ist das Profil sowohl vollständig an seinen Sicht flächen kennzeichnend, hinweisend, signalisierend oder dekorierend mit entsprechenden Motiven ausgebildet und/oder auch antiadhäsiv oder adhäsiv, bestimmt durch den Anwendungszweck, ob Schalfläche oder Lauffläche, ausgerüstet.The profile is both completely in view thanks to the lamination, which is designed as transfer printing surface marking, indicative, signaling or decorating with appropriate motifs and / or also anti-adhesive or adhesive, determined by the application, whether formwork surface or Tread, equipped.
Die für sich betrachtet bekannten Maßnahmen, ein Profil mittels einer Bewehrungseinlage zu armieren, es zu stabilisieren und dessen mechanisch-physikalischen Eigenschaften zu verbessern, sind in den Unteran sprüchen erfindungsgemäß weiterentwickelt.The known measures considered to reinforce a profile by means of reinforcement insert it too Stabilize and improve its mechanical-physical properties are in the Unteran sayings further developed according to the invention.
Die in den Unteransprüchen aufgezeigten Ausbildungen der Bewehrungseinlage, von deren Verbindung mit dem Gemisch, der Wahl des Werkstoffes, deren Gestaltung bis hin zur Profilierung als Hohlprofil oder deren funktionellen Optionen, z. B. ein Vereisen einer aus dem erfindungsgemäßen Profil hergestellten Laufplanke bzw. -bohle zu verhindern, so deren elektrische Leitfähigkeit dafür erfindungsgemäß genutzt wird, sind eine Fortbildung gattungsgemäßer Profile.The designs of the reinforcement insert shown in the subclaims, of their connection with the mixture, the choice of the material, their design up to the profiling as a hollow profile or their functional options, e.g. B. icing of a gangway made from the profile according to the invention Preventing or screed, so their electrical conductivity is used according to the invention are one Training of generic profiles.
Auch die gleichsam für sich betrachtet bekannte Maßnahme in einem Profil Hohlräume auszubilden, um dadurch sowohl die mechan.-physikal. Beanspruchbarkeit des Profiles, als auch die Parameter für dessen ökonomische Fertigung zu verbessern, ist in der vorliegenden Erfindung dadurch fortgebildet, daß der/die Hohlräume gegenüber dem sie umgebenden Gemisch mittels einer rohrähnlich geformten Bewehrungsein lage, die eventuell mit bekannten Vorkehrungen für eine form- und/oder kraftschlüssige Verbindung versehen sind, begrenzt sind.The known measure, as it were, to form cavities in a profile in order to thereby both the mechanical-physical. Resilience of the profile, as well as the parameters for it Improving economic production is further developed in the present invention in that the Cavities to the surrounding mixture by means of a tubular reinforcement location, which may be provided with known arrangements for a positive and / or non-positive connection are, are limited.
Von dem Erfindungsgedanken miterfaßt ist selbstverständlich auch die Ausbildung des/der Hohlraumes in der Art, daß der Hohlraum z. B. nach einer Außenseite des Profiles U-förmig offen ist.Of course, the concept of the invention also includes the formation of the cavity in the way that the cavity z. B. is open to an outside of the profile U-shaped.
Die Mannigfaltigkeit der Ausgestaltungsmöglichkeiten der vorliegenden Erfindung ergibt sich aus den Varia tionen der das zu extrudierende bzw. zu pultierende Gemisch bildenden Natur- und Kunststoffe, so führt der hohe Anteil der Naturstoffe in dem Gemisch zu einer unerwartet hohen Formstabilität des noch thermoplas tischen Profiles. Auch die Werkstoffwahl und die Ausbildung der Bewehrungseinlage bis hin zu der Funktion "Schutz vor Vereisung" oder als Kantenschutz sind Beleg für den Variationsreichtum der Benutzung des er findungsgemäßen Profiles.The variety of design options of the present invention results from the Varia tion of the natural and synthetic materials forming the mixture to be extruded or pulted, so the high proportion of natural substances in the mixture leads to an unexpectedly high dimensional stability of the still thermoplas table profile. Also the choice of material and the design of the reinforcement insert up to the function "Protection against icing" or as edge protection are proof of the variety of uses of the he profile according to the invention.
Besonders bedeutsam ist die Nutzung der hohen Eigenstabilität des noch plastischen und daher noch plas tisch formbaren Profiles für unterschiedliche individuelle Gestaltungen, bis hin zur Formgebung von Unikaten. Die Erfindung wird anhand einer Zeichnung näher erläutert.The use of the high inherent stability of the still plastic and therefore still plas is particularly important table-shaped profiles for different individual designs, up to the shaping of unique pieces. The invention is explained in more detail with reference to a drawing.
