Definitions
- the invention relates to solid or hollow chamber plastic profiles, in particular for absorbing tensile, bending and / or compressive load, as they are used in particular as Isolierstege in composite profiles of metal profile parts used.
- Known profiles of this type are for example from the DE 32 03 631 A1 or the DE 38 01 564 A1 known and used as a thermal insulation profiles between metal profile parts and made of high-strength plastic with poor thermal conductivity properties, such as a glass fiber reinforced polyamide. These composite profiles are mainly used in the manufacture of window or facade elements.
- a generic profile is also used by the JP-A-03 240 515 specified.
- the object of the invention is to develop the above-mentioned full or hollow chamber profile so that the disadvantages described above are pushed back as far as possible.
- the cell structure of the core region is selected closed cell, so that a plurality of insulating gas volumes in the plastic profile is present. Thus, an optimal heat transfer resistance is obtained.
- the fine-poredness and closed-celledness of the core region is also important from the viewpoint that the mechanical properties do not decrease in parallel with the decrease in density, but are largely retained.
- the profiles of the invention can be prepared analogously to those in the DE 32 03 631 C2 and the DE 195 10 944 C1 described method.
- the fine-pored core is thereby by foaming the second plastic material by means of known agents such.
- the profile thickness can be made larger at the same meter weight, resulting in significantly higher stiffness or bending strength of the plastic profile.
- doubled transverse stiffness factors are obtained with only slightly increased wall thickness, and this results in particular from the use of fine-pored structures in the core region, whose mechanical properties have no linear relationship with the density, as is the case of free-blown, known large-pore Cell structures is common.
- the porosity or the cell structure is substantially uniform over the entire cross section of the core region.
- the structure of the profile will preferably be formed such that the core region with its cell structure is completely enclosed by the surface layer and the inner surface layer defining the hollow chamber or cavities.
- the surface layer, the core region and the inner surface layer are preferably formed as sandwich structures at least in partial regions of the profile, in which the surface layer, the inner surface layer and the core region enclosed between them form layers arranged essentially parallel to one another.
- the first, second and third plastic materials used to make the inventive profiles may be the same or different and may contain reinforcing agents, fillers, modifiers and / or additives.
- the reinforcing materials are short, long and / or continuous fibers, in particular glass, carbon, aramid or natural fibers are used.
- Suitable fillers are glass beads, glass bubbles, wollastonite, mica and nanoparticles.
- the group of modifiers includes impact modifiers, UV heat stabilizers, conductivity substances, nucleating agents, coupling agents, etc.
- flange For profiles which have an integrally formed flange, which is used by a corresponding groove of the metal profiles of a composite thermal insulation profile, it is recommended to provide the flange on its surface at least partially with a fine-pored coating, for example by coextrusion.
- the flange can be made somewhat undersized with respect to the groove of the associated metal profile receiving it, and the groove walls can be pressed against the flange by a knurl operation and deform the fine-pored coating.
- a particularly good positive engagement between the flange of the profile and the groove of the metal profile is achieved.
- the mean cell size of the cell structure of the core region should be in particular in the range of 0.005 to 0.1 mm (diameter), preferably in the range of 0.02 to 0.05 mm. In these areas, there is an optimum of mass saving and preservation of mechanical properties.
- the density of the material in the core area can be reduced by up to about 60% compared to the density of the raw material.
- plastic materials which are suitable as raw materials for the production of the profiles according to the invention, ranging from thermoplastic, thermoset to elastomeric plastic materials or mixtures thereof.
- the same raw material will be used for the first, the second and optionally the third plastic material, whereby it can be achieved by appropriate process control that the compact surface layer results quasi automatically and for the formation of the compact surface layer next to the porous core region not necessarily on a co-extrusion process must be resorted to.
- the core region of the profile according to the invention is made of a second plastic material, which differs from the plastic material of the surface layer (first plastic material). This then opens the possibility that a high-quality plastic material is used for the formation of the surface layer, while in the core area a much cheaper plastic material can be used. The same applies to the third plastic material.
- the profiles of the invention are coated for special applications on the surface completely or at least partially with primers, primers and / or conductive paints.
- the profiles according to the invention can be prepared for aftertreatment processes such as the powder wet-paint or anodization process.
- profiles according to the invention are in particular heat insulation profiles in the production of metal-plastic composite profiles.
- the invention finally thermally insulated composite profiles, in particular for the production of windows, doors, facades or the like with an inner and an outer metal profile, which are connected via at least one inventive plastic profile as described above and held at a predetermined distance from each other.
- FIG. 1 shows a plastic full profile provided with the reference numeral 10 with a surface layer 12 of a compact, non-porous first plastic material and a core portion 14 of a fine-pored second plastic material having a closed cell structure.
- the profile itself is seen in cross section of a web 16 and a flange 18 together, which has a trapezoidal shape in cross section.
- the flange 18 is formed so that it can be received by a complementary shaped groove of a metal profile part, which forms part of a composite profile.
- a metal profile part which forms part of a composite profile.
- the profile 10 is arranged in its simplest form a mirror image of the flange 18 shown have a further flange, so that two metal profile parts held on the profile 10 at a distance and can be connected together.
- the thickness s 1 of the core area is 1.76 mm (measured on the web 16) and the wall thickness s 2 of the surface layer 12 is approximately the same on the entire profile 10, ie both in the web area 16 and in the flange area 18, and is for example 0.12 mm.
- the closed-cell, fine-pored core region 14 extends into the trapezoidal structure of the flange 18.
- the pore size of the cells in the core region of the profiles according to the invention is in the range of about 0.02 to 0.05 mm.
- the transverse stiffness factor is given per mm web height h, the weight per meter for a web with a web height of approx. 20 mm h.
- Liquid CO 2 was used to form the core region.
- Table I shows clearly that in the profile according to the invention a weight reduction by 28% can be achieved without the transverse stiffness suffers appreciably. Only a decrease of 6.8% is observed.

Abstract
Description
Die Erfindung betrifft Voll- oder Hohlkammerkunststoffprofile, insbesondere zur Aufnahme von Zug-, Biege- und/oder Druckbelastung, wie sie insbesondere als Isolierstege in Verbundprofilen aus Metallprofilteilen zum Einsatz gelangen.The invention relates to solid or hollow chamber plastic profiles, in particular for absorbing tensile, bending and / or compressive load, as they are used in particular as Isolierstege in composite profiles of metal profile parts used.
Bekannte Profile dieser Art sind beispielsweise aus der
Diese Verbundprofile und damit auch die Voll- oder Hohlkammerprofile aus Kunststoff sind erheblichen Einwirkungen ausgesetzt, beispielsweise Windbelastungen, lotrechten Lasten, insbesondere hervorgerufen durch das Eigengewicht einer Verglasung und vor allem herrührend von Temperaturdifferenzen zwischen dem außen und dem innen angeordneten Metallprofilteil des Verbundprofils. Je weniger sich das Kunststoffmaterial der Isolierprofile unter klimatischem Einfluß, nämlich Temperatur und Luftfeuchtigkeit, verändert, desto geringer sind die daraus resultierenden Spannungen an der Nahtstelle von Kunststoff- und Metallprofil.These composite profiles and thus also the solid or hollow profiles made of plastic are exposed to significant effects, such as wind loads, vertical loads, in particular caused by the weight of a glazing and especially stemming from temperature differences between the outside and the inside arranged metal profile part of the composite profile. The less the plastic material of the insulating profiles under climatic influence, namely temperature and humidity changes, the lower the resulting stresses at the interface of plastic and metal profile.
Bislang wurde versucht, mit höheren Füllstoffgraden des verwendeten Kunststoffmaterials, insbesondere unter Verwendung von mineralischen Verstärkungs- und Füllstoffen, insbesondere Glasfasern, das Ausdehnungsverhalten der Kunststoffmaterialien günstig zu beeinflussen, nämlich deren Ausdehnungskoeffizienten herabzusetzen.So far, attempts have been made with higher filler degrees of the plastic material used, in particular using mineral reinforcing and fillers, in particular glass fibers, to influence the expansion behavior of the plastic materials low, namely to reduce their expansion coefficient.
Höhere Füllgrade führen aber gleichzeitig zu einer Reihe von Nachteilen. Neben den erhöhten Rohstoffkosten und höherem Gewicht der Isolierprofile entstehen Probleme in der Verarbeitung des Rohmaterials, insbesondere im Hinblick auf Verschleiß und Produktivität. Glasfaserverstärkte Kunststoffe können nach dem Extrudieren und Erstarren unerwünschte Anisotropien, Eigenspannungen, eine stark abnehmende Duktilität und vor allem wiederum eine höhere Wärmeleitfähigkeit als der reine Kunststoff aufweisen.Higher filling levels, however, also lead to a number of disadvantages. In addition to the increased raw material costs and higher weight of the insulating profiles, problems arise in the processing of the raw material, in particular with regard to wear and productivity. After extrusion and solidification, glass-fiber reinforced plastics can exhibit undesired anisotropies, residual stresses, greatly decreasing ductility and, above all, a higher thermal conductivity than the pure plastic.

Aufgabe der Erfindung ist es, das eingangs genannte Voll- oder Hohlkammerprofil so weiterzubilden, daß die vorstehend beschriebenen Nachteile möglichst weit zurückgedrängt werden.The object of the invention is to develop the above-mentioned full or hollow chamber profile so that the disadvantages described above are pushed back as far as possible.
Diese Aufgabe wird durch die Merkmalskombination des Anspruchs 1 bzw. des Anspruchs 12 gelost.This object is achieved by the combination of features of claim 1 and claim 12.
Die Zellstruktur des Kernbereiches wird geschlossenzellig gewählt, so daß eine Vielzahl von isolierenden Gasvolumina in dem Kunststoffprofil vorhanden ist. Damit wird ein optimaler Wärmedurchgangswiderstand erhalten. Die Feinporigkeit und Geschlossenzelligkeit des Kernbereichs ist auch unter dem Gesichtspunkt wichtig, daß die mechanischen Eigenschaften nicht mit der Abnahme der Dichte parallel abnehmen, sondern in großem Umfang erhalten bleiben.The cell structure of the core region is selected closed cell, so that a plurality of insulating gas volumes in the plastic profile is present. Thus, an optimal heat transfer resistance is obtained. The fine-poredness and closed-celledness of the core region is also important from the viewpoint that the mechanical properties do not decrease in parallel with the decrease in density, but are largely retained.
Herstellen lassen sich die erfindungsgemäßen Profile analog den in der
Durch die Beschränkung des kompakten, nicht-porösen ersten Kunststoffmaterials auf die Ausbildung einer Oberflächenschicht des Kunststoffprofils und die Verwendung eines Kernbereiches mit einer feinporigen Zellstruktur wird eine erhebliche Reduzierung der Wärmeleitfähigkeit des Profils insgesamt erreicht. Die Reduzierung der Wärmeleitfähigkeit ist im wesentlichen auf die Dichtereduzierung bzw. die Gaseinschlüsse in dem Kernbereich zurückzuführen. Diese ergibt parallel dazu ein geringeres Gewicht des Profils und führt zu erheblichen Einsparungen an Rohstoff bei der Herstellung des Kunststoffprofiles. Die möglichen Rohstoffeinsparungen betragen je nach Wanddicke der Oberflächenschicht(en) und dem Einsatzfall bis zu 60 %. Bei gleichen Abmessungen des Profils gelangt man bei nur geringen Einbußen beim Steifigkeitsfaktor (Querbiegesteifigkeit) zu erheblich verminderten Metergewichten.By limiting the compact, non-porous first plastic material to the formation of a surface layer of the plastic profile and the use of a core region with a fine-pored cell structure, a significant reduction in the thermal conductivity of the profile is achieved overall. The reduction of the thermal conductivity is due essentially to the reduction in density or the gas inclusions in the core area. This results in parallel to a lower weight of the profile and leads to significant savings in raw material in the production of the plastic profile. Depending on the wall thickness of the surface layer (s) and the application, the possible savings in raw materials are up to 60%. With the same dimensions of the profile can be achieved with only small losses in the stiffness factor (transverse bending stiffness) to significantly reduced meter weights.
Gegenüber herkömmlichen Profilen kann bei gleichem Metergewicht die Profildicke größer dimensioniert werden, woraus sich erheblich höhere Steifigkeiten bzw. Biegefestigkeiten des Kunststoffprofils ergeben. Überraschenderweise erhält man beispielsweise verdoppelte Quersteifigkeitsfaktoren bei nur geringfügig erhöhter Wanddicke, und dies resultiert insbesondere aus der Verwendung von feinporigen Strukturen im Kernbereich, deren mechanische Eigenschaften keinen linearen Zusammenhang mit der Dichte aufweisen, wie dies von freigeschäumten, bekannten großporigen Zellstrukturen geläufig ist.Compared to conventional profiles, the profile thickness can be made larger at the same meter weight, resulting in significantly higher stiffness or bending strength of the plastic profile. Surprisingly, for example, doubled transverse stiffness factors are obtained with only slightly increased wall thickness, and this results in particular from the use of fine-pored structures in the core region, whose mechanical properties have no linear relationship with the density, as is the case of free-blown, known large-pore Cell structures is common.
Um optimale mechanische Eigenschaften, insbesondere Festigkeit zu erreichen, wird darauf geachtet, daß die Porosität oder die Zellstruktur im wesentlichen über den gesamten Querschnitt des Kernbereichs gleichförmig ist. Insbesondere ist von Bedeutung die Zellgröße innerhalb eines vorgegebenen Rahmens zu halten, beispielsweise innerhalb des weiter unten empfohlenen, und gröbere Zellen an vereinzelten Stellen im Querschnitt zu vermeiden.In order to achieve optimal mechanical properties, in particular strength, it is ensured that the porosity or the cell structure is substantially uniform over the entire cross section of the core region. In particular, it is important to keep the cell size within a given framework, for example within the range recommended below, and to avoid coarser cells at isolated points in the cross section.
Im Falle der Hohlkammerprofile mit innerer Oberflächenschicht aus kompaktem Kunststoffmaterial wird man bevorzugt die Struktur des Profils so ausbilden, dass der Kernbereich mit seiner Zellstruktur von der Oberflächenschicht und der die Hohlkammer oder Hohlkammern definierenden inneren Oberflächenschicht vollkommen eingeschlossen ist.In the case of the hollow chamber profiles with inner surface layer of compact plastic material, the structure of the profile will preferably be formed such that the core region with its cell structure is completely enclosed by the surface layer and the inner surface layer defining the hollow chamber or cavities.
Bevorzugt werden hierbei die Oberflächenschicht, der Kernbereich und die innere Oberflächenschicht mindestens in Teilbereichen des Profils als Sandwich-Struktur ausgebildet, bei der die Oberflächenschicht, die innere Oberflächenschicht und der dazwischen eingeschlossene Kernbereich im wesentlichen parallel zueinander angeordnete Schichten bilden.In this case, the surface layer, the core region and the inner surface layer are preferably formed as sandwich structures at least in partial regions of the profile, in which the surface layer, the inner surface layer and the core region enclosed between them form layers arranged essentially parallel to one another.
Die zur Herstellung der erfindungsgemäßen Profile verwendeten ersten, zweiten und dritten Kunststoffmaterialien können gleich oder verschieden sein und können Verstärkungsstoffe, Füllstoffe, Modifier und/oder Zuschlagstoffe enthalten. Bei den Verstärkungsstoffen kommen Kurz-, Lang- und/oder Endlosfasern, insbesondere Glas-, Kohle-, Aramid- oder Naturfasern zum Einsatz. Als Füllstoffe eignen sich Glaskugeln, Glashohlkugeln, Wollastonit, Glimmer und Nanopartikel.The first, second and third plastic materials used to make the inventive profiles may be the same or different and may contain reinforcing agents, fillers, modifiers and / or additives. The reinforcing materials are short, long and / or continuous fibers, in particular glass, carbon, aramid or natural fibers are used. Suitable fillers are glass beads, glass bubbles, wollastonite, mica and nanoparticles.
Unter die Gruppe der Modifier fallen Schlagzähmodifier, UV-Hitzestabilisatoren, Leitfähigkeitssubstanzen, Keimbildner, Kopplungsagentien etc..The group of modifiers includes impact modifiers, UV heat stabilizers, conductivity substances, nucleating agents, coupling agents, etc.
Bei Profilen, welche einen angeformten Flansch aufweisen, der von einer entsprechenden Nut der Metallprofile eines Wärmedämmverbundprofiles eingesetzt wird, empfiehlt es sich, den Flansch an seiner Oberfläche mindestens bereichsweise mit einer feinporigen Beschichtung, beispielsweise durch Koextrusion, zu versehen. Dadurch kann der Flansch gegenüber der ihn aufnehmenden Nut des zugehörigen Metallprofiles etwas untermaßig hergestellt werden, und die Nutwände können durch eine Rändeloperation an den Flansch angedrückt werden und die feinporige Beschichtung verformen. Dadurch wird ein besonders guter Formschluß zwischen dem Flansch des Profiles und der Nut des Metallprofiles erreicht.For profiles which have an integrally formed flange, which is used by a corresponding groove of the metal profiles of a composite thermal insulation profile, it is recommended to provide the flange on its surface at least partially with a fine-pored coating, for example by coextrusion. As a result, the flange can be made somewhat undersized with respect to the groove of the associated metal profile receiving it, and the groove walls can be pressed against the flange by a knurl operation and deform the fine-pored coating. As a result, a particularly good positive engagement between the flange of the profile and the groove of the metal profile is achieved.
Die mittlere Zellgröße der Zellstruktur des Kernbereiches sollte insbesondere im Bereich von 0,005 bis 0,1 mm (Durchmesser) liegen, vorzugsweise im Bereich von 0,02 bis 0,05 mm. In diesen Bereichen ist ein Optimum der Masseneinsparung und Erhalt der mechanischen Eigenschaften gegeben.The mean cell size of the cell structure of the core region should be in particular in the range of 0.005 to 0.1 mm (diameter), preferably in the range of 0.02 to 0.05 mm. In these areas, there is an optimum of mass saving and preservation of mechanical properties.
Die Dichte des Materials im Kernbereich kann gegenüber der Dichte des Rohmaterials um bis zu ca. 60 % vermindert werden.The density of the material in the core area can be reduced by up to about 60% compared to the density of the raw material.
Die Kunststoffmaterialien, die als Rohstoffe für die Herstellung der erfindungsgemäßen Profile in Frage kommen, reichen von thermoplastischen, duroplastischen bis zu elastomeren Kunststoffmaterialien oder Mischungen hieraus.The plastic materials which are suitable as raw materials for the production of the profiles according to the invention, ranging from thermoplastic, thermoset to elastomeric plastic materials or mixtures thereof.
Normalerweise wird man für das erste, das zweite und gegebenenfalls das dritte Kunststoffmaterial dasselbe Rohmaterial verwenden, wobei durch entsprechende Verfahrensführung erreicht werden kann, daß sich die kompakte Oberflächenschicht quasi automatisch ergibt und für die Bildung der kompakten Oberflächenschicht neben dem porösen Kernbereich nicht unbedingt auf ein Koextrusionsverfahren zurückgegriffen werden muß.Normally, the same raw material will be used for the first, the second and optionally the third plastic material, whereby it can be achieved by appropriate process control that the compact surface layer results quasi automatically and for the formation of the compact surface layer next to the porous core region not necessarily on a co-extrusion process must be resorted to.
In besonderen Fällen wird der Kernbereich des erfindungsgemäßen Profils aus einem zweiten Kunststoffmaterial hergestellt, welches sich von dem Kunststoffmaterial der Oberflächenschicht (erstes Kunststoffmaterial) unterscheidet. Dies eröffnet dann die Möglichkeit, daß für die Bildung der Oberflächenschicht ein hochwertiges Kunststoffmaterial verwendet wird, während im Kernbereich ein preislich wesentlich günstigeres Kunststoffmaterial Verwendung finden kann. Gleiches gilt für das dritte Kunststoffmaterial.In special cases, the core region of the profile according to the invention is made of a second plastic material, which differs from the plastic material of the surface layer (first plastic material). This then opens the possibility that a high-quality plastic material is used for the formation of the surface layer, while in the core area a much cheaper plastic material can be used. The same applies to the third plastic material.
Die erfindungsgemäßen Profile werden für besondere Anwendungszwecke an der Oberfläche vollständig oder mindestens bereichsweise mit Primern, Haftlacken und/oder Leitlacken beschichtet. Damit lassen sich die erfindungsgemäßen Profile auf Nachbehandlungsverfahren wie das Pulver-Naßlackier- oder Anodisierverfahren vorbereiten.The profiles of the invention are coated for special applications on the surface completely or at least partially with primers, primers and / or conductive paints. Thus, the profiles according to the invention can be prepared for aftertreatment processes such as the powder wet-paint or anodization process.
Verwendungszweck der erfindungsgemäßen Profile sind insbesondere Wärmedämmprofile bei der Herstellung von Metall-Kunststoffverbundprofilen.Use of the profiles according to the invention are in particular heat insulation profiles in the production of metal-plastic composite profiles.
Gegenstand der Erfindung sind schließlich wärmegedämmte Verbundprofile, insbesondere für die Herstellung von Fenstern, Türen, Fassaden oder dergleichen mit einem inneren und einem äußeren Metallprofil, welche über mindestens ein erfindungsgemäßes Kunststoffprofil wie zuvor beschrieben verbunden und auf einem vorgegebenen Abstand voneinander gehalten sind.The invention finally thermally insulated composite profiles, in particular for the production of windows, doors, facades or the like with an inner and an outer metal profile, which are connected via at least one inventive plastic profile as described above and held at a predetermined distance from each other.
