Description

Die Erfindung betrifft ein Isoliermaterial.The invention relates to an insulating material.

Isoliermaterialien dienen zur Isolierung gegen Lärm und ungewünscht tiefe oder hohe Temperaturen oder zu deren Dämmung. Sie kommen zum Einsatz in Gebäuden, z.B. bei der Kerndämmung (Hartschaumstoffplatten, etc.), in Fahrzeugen (Melamin-Aminoplast, Polyurethanschaum), beim Transport von Lebensmitteln, Medikamenten und dergleichen (Polystyrolhartschaum bzw. Styropor) und bei vielen anderen Orten und Gelegenheiten. Entsprechend der vielseitigen und verbreiteten Verwendung von Isoliermaterialien ist es wichtig, dass diese kostengünstig herstellbar sind. Außerdem sollen sie einfach und möglichst aus nachwachsenden Rohstoffen herstellbar sein. Sie sollen des Weiteren möglichst ein geringes Gewicht haben.Insulating materials are used for insulation against noise and unwanted low or high temperatures or for their insulation. They are used in buildings, e.g. in core insulation (rigid foam boards, etc.), in vehicles (melamine-aminoplast, polyurethane foam), in the transport of foodstuffs, medicines and the like (polystyrene foam) and in many other places and occasions. According to the versatile and widespread use of insulating materials, it is important that they are inexpensive to produce. In addition, they should be easy and possible to produce from renewable resources. Furthermore, they should have as little weight as possible.

Im Fahrzeugbau werden beispielsweise für die Isolierung zwischen Außenblech und Innenverkleidung neben Melaminharzen Schaumstoffe eingesetzt. Bis zur einbaufertigen Isolierlage sind mehrere Schritte erforderlich. Der durch den Schaumprozess aus einem aus Erdöl gewonnenen Ausgangsmaterial hergestellte Schaumstoffblock muss auf die benötigte Dicke zugeschnitten und die so gebildete Lage dann gerollt oder zu Platten verarbeitet werden. Anschließend wird die Lage kaschiert. Ein schnellerer Herstellungsprozess ist wünschenswert, ebenso eine umweltfreundliche Alternative mit nachwachsenden Rohstoffen.In the automotive industry, foams are used in addition to melamine resins, for example, for the insulation between outer panel and interior trim. Up to the ready-to-install insulating layer several steps are required. The foam block produced by the foaming process from a raw material derived from petroleum must be cut to the required thickness and the layer thus formed then rolled or processed into sheets. Then the situation is laminated. A faster manufacturing process is desirable as well an environmentally friendly alternative with renewable raw materials.

Bei Möbeln, Türen, Sportgeräten wie Snowboards, Flugzeugen und Gebäudewänden beispielsweise werden Schichten bzw. Lagen mit Wabenstruktur zur Aussteifung, Gewichtseinsparung oder Wärmedämmung eingesetzt. Die Waben-Lagen sind beidseits mit Außenlagen versehen. Üblicherweise geschieht die Herstellung in mehreren Schritten und mit Lagen begrenzter Abmessung.In furniture, doors, sports equipment such as snowboards, aircraft and building walls, for example, layers or layers are used with honeycomb structure for stiffening, weight reduction or thermal insulation. The honeycomb layers are provided on both sides with outer layers. Usually, the production takes place in several steps and with layers of limited dimensions.

Aus der DE 40 17 852 A1 ist eine Metallplatte mit Wabenstruktur bekannt, bei der die Waben mindestens einseitig durch eine Deckschicht geschlossen sind. Die Deckschicht wird mit Über- oder Unterdruck in Formschluss mit der Zellenwandung aufgebracht. Der so gebildete Sandwich-Körper kann z.B. zu halbzylindrischen Formkörpern umgeformt werden, sofern er ein warmhärtbares Bindemittel enthält.From the DE 40 17 852 A1 a honeycomb metal plate is known in which the honeycombs are closed at least on one side by a cover layer. The cover layer is applied with positive or negative pressure in positive engagement with the cell wall. The sandwich body thus formed can be converted, for example, to semicylindrical molded bodies, provided that it contains a thermosetting binder.

In der DE 100 02 533 A1 ist die Herstellung einer Kunststoffwabe beschrieben, die aus Kunststoff extrudiert ist. Die Wabenstrukturen können beim Extrudieren geformt werden, wobei zunächst bandartige rechteck-, rundwellen- oder trapezwellenförmige Stränge, sozusagen Halbwaben, produziert werden. Zur Bildung einer Kunststoffwabe werden die einzelnen Wabenstege der Halbwaben an bestimmten Stegabschnitten durch Schweißen, Nieten, etc. unlösbar verbunden. Durch Einmischen von Zusatzstoffen wie Glasfasern, Farben, etc. in einzelne Kunststoffstränge können in bestimmten Abschnitten gewünschte Wabenstruktureigenschaften erreicht werden.In the DE 100 02 533 A1 the production of a plastic honeycomb is described, which is extruded from plastic. The honeycomb structures can be formed during extrusion, wherein initially band-like rectangular, round-wave or trapezoidal-shaped strands, so-called semi-honeycombs, are produced. To form a plastic honeycomb, the individual honeycomb webs of the half-honeycombs are permanently joined to certain web sections by welding, riveting, etc. By mixing in additives such as glass fibers, colors, etc. in individual plastic strands desired honeycomb structural properties can be achieved in certain sections.

Bei einem Sandwichelement gemäß DE 10 2004 024 878 A1 ist eine Mittellage vorgesehen, die in einem Arbeitsschritt unter Anwendung eines Umformverfahrens (Tiefziehen, Pressen, Walzen) aus Blech oder verformbaren Kunststoffplatten hergestellt wird. Die Mittellage ist nicht als Wabenkonstruktion ausgeführt, sondern in Form eines periodisch wiederkehrenden zweifach gekrümmten Schalentragwerks mit gegensinnigen Hauptkrümmungen, wodurch eine größere Klebefläche zwischen der Mittellage und den beiden Deckschichten vorliegt.In a sandwich element according to DE 10 2004 024 878 A1 a center layer is provided, which is produced in one step using a forming process (deep drawing, pressing, rolling) of sheet metal or deformable plastic plates. The middle layer is not designed as a honeycomb construction, but in the form of a periodically recurring double-curved shell structure with opposing main curvatures, whereby there is a larger adhesive surface between the middle layer and the two outer layers.

Ein aus der WO 2008/141689 A1 bekannter Wabenkörper, dessen Waben vier-, sechs-, achteckig oder kreisförmig sein können, umfasst einen Kern mit dicht abschließenden Deckschichten. Zur Herstellung des Wabenkörpers werden Platten aus z.B. vorimprägniertem Papier hergestellt, Halbwaben in diesen geformt und dann aus jeweils zwei Halbwabenplatten Wabenplatten gepresst oder zu diesen verklebt.One from the WO 2008/141689 A1 known honeycomb whose honeycomb may be four-, six-, octagonal or circular, comprising a core with tight-fitting cover layers. For the production of the honeycomb body plates are made of eg prepreg paper, formed semi-honeycomb in these and then pressed from each two honeycomb panels honeycomb panels or glued to these.

Eine Aussteifungsstruktur mit senkrecht angeordneten Aussteifungsstegen, die in der DE 44 27 920 A1 beschrieben ist, umfasst z.B. rechteckförmige Waben, deren Seitenmitten durch Aussteifungsstege verbunden sind. Die Aussteifungsstege sind rechtwinklig zu den Seitenwänden angeordnet. Damit sollen die Biegeeigenschaften der Aussteifungsstruktur verbessert werden.A stiffening structure with vertically arranged stiffening webs, which in the DE 44 27 920 A1 is described, for example, includes rectangular honeycombs whose sides are connected by stiffening webs. The stiffening webs are arranged at right angles to the side walls. This should improve the bending properties of the stiffening structure.

Der Erfindung liegt die Aufgabe zugrunde, ein Isoliermaterial zur Verfügung zu stellen, das einfach und kostengünstig, auch als Endlosmaterial, zu fertigen ist und ein geringes Gewicht hat. Das Isoliermaterial soll aus erdölbasierten, aber auch aus nachwachsenden Rohstoffen herstellbar sein.The invention has for its object to provide an insulating material available, which is simple and inexpensive to manufacture, even as a continuous material, and has a low weight. The insulating material should be produced from petroleum-based, but also from renewable raw materials.

Diese Aufgabe ist bei einem Isoliermaterial mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen des erfindungsgemäßen Isoliermaterials sind Gegenstand der Unteransprüche.This object is achieved with an insulating material having the features of claim 1. Advantageous developments of the insulating material according to the invention are the subject of the dependent claims.

Die Erfindung betrifft somit ein Isoliermaterial, bestehend aus einer Materiallage mit durch Verformung gebildeten becherförmigen Vertiefungen, wobei die Außenwände benachbarter becherförmiger Vertiefungen durch Verbindungsstege verbunden sind, die mit den Außenwänden durch die Verformung integriert ausgebildet sind und sich durchgehend von der Oberfläche der Materiallage bis zu der Tiefe der becherförmigen Vertiefungen erstrecken. Die Verbindungsstege und Außenwände der Vertiefungen umgrenzen jeweils Kammern, deren Boden durch die Materiallage gebildet wird.The invention thus relates to an insulating material consisting of a sheet of material with cup-shaped depressions formed by deformation, wherein the outer walls of adjacent cup-shaped depressions are connected by connecting webs, which are integrally formed with the outer walls by the deformation and continuously from the surface of the material layer to the Extend depth of the cup-shaped recesses. The connecting webs and outer walls of the depressions each define chambers whose bottom is formed by the material layer.

Unter "becherförmige Vertiefungen" sollen alle Vertiefungen verstanden werden, die für den erfindungsgemäßen Zweck geeignet sind, d.h. ein ausreichendes Luftvolumen aufnehmen können. Somit kommt es nicht auf die Gestalt eines Bechers an, sondern es können andere Wölbungen oder Vorsprünge mit Innenvolumen gewählt werden, etwa mit Kuppelform, Pyramidenstumpfform, Wabenform, Quaderform, etc. All diese und ähnliche Gestalten bzw. Formen sollen durch den Begriff Becherform umfasst sein, der für ein negatives Volumen-Relief steht.By "cup-shaped wells" is meant all wells suitable for the purpose of the present invention, i. can absorb a sufficient volume of air. Thus, it does not depend on the shape of a cup, but other bulges or protrusions with internal volume can be selected, such as dome shape, truncated pyramid shape, honeycomb shape, cuboid shape, etc. All of these and similar shapes or forms should be encompassed by the term cup shape which stands for a negative volume relief.

Das erfindungsgemäße Isoliermaterial kann z.B. hergestellt werden, indem ein Ausgangsmaterial durch Verformen in einer Rollen- oder Plattenpresse, Tiefziehen oder Spritzen in eine Form gebracht wird, die genügend große Vertiefungen "in Becherform" (z.B. wie eine Wabe, ein Kreis, ein Viereck, etc.) und durchgehend bzw. gleichmäßig hohe Kämme oder Berge aufweist, welche in gleicher Tiefe wie die "Becherböden" enden. Das Isoliermaterial enthält somit auf beiden Seiten der Lage Kammern (auf einer Seite die Vertiefungen und auf der anderen Seite die Zwischenräume zwischen den Wänden der Vertiefungen), die nicht miteinander verbunden sind. Die Fertigung des in der Richtung der Flächenerstreckung luftdichten oder porösen Isoliermaterials kann in einem Schritt erfolgen. Es kann vorteilhaft ein bahnenförmiges bzw. Endlosmaterial hergestellt werden. Das Isoliermaterial kann auch in Plattenform hergestellt werden.The insulating material according to the invention may e.g. are prepared by a starting material by deformation in a roll or plate press, deep drawing or spraying is placed in a mold having sufficiently large wells "in cup form" (eg, such as a honeycomb, a circle, a square, etc.) and continuously or . uniformly high crests or mountains, which end in the same depth as the "cup bases". The insulating material thus contains on both sides of the layer chambers (on one side the recesses and on the other side the spaces between the walls of the recesses), which are not interconnected. The production of the airtight or porous insulating material in the direction of surface extension can be done in one step. It can be advantageously produced a web-shaped or endless material. The insulating material can also be produced in sheet form.

Die Vertiefungen und auch die Hohlräume zwischen den Wänden der Vertiefungen und den Verbindungsstegen auf der anderen Seite des Lagenmaterials enthalten den Isolator Luft. Die Verbindungsstege bzw. -wände zwischen den Vertiefungen stellen sicher, dass keine Luft die Materiallage in horizontaler Richtung, d.h. die Lagenschicht, durchdringen kann. Für bestimmte Anwendungen (Schallisolierung) kann das Material porös (nicht offen) gewählt werden. Den Abschluss des Isoliermaterials an den Außenflächen können beispielsweise zwei Bleche bilden, zwischen denen die Isoliermateriallage eingeschoben bzw. eingedrückt worden ist. Die mit der Isoliermateriallage in Kontakt stehenden Bleche dienen als deren Außenlage und schließen die Luftkammern in den becherförmigen Vertiefungen und den Zwischenräumen luftdicht ab. Die Isoliermateriallage kann auch selbst mit einer oder zwei Außenlagen dichtend abgedeckt sein. An den Schmalseiten ist aufgrund der Verbindungsstege bzw. -wände keine Abdeckschicht notwendig, da die Geometrie des Lagenkörpers bereits dem Luftaustausch eine Barriere setzt. Das erfindungsgemäße Material ist somit gut isolierend und hat relativ geringes Gewicht.The recesses and also the voids between the walls of the recesses and the connecting webs on the other side of the sheet material contain the insulator air. The connecting webs or walls between the depressions ensure that no air can penetrate the material layer in the horizontal direction, ie the layer layer. For certain applications (soundproofing), the material may be porous (not open). The conclusion of the insulating material on the outer surfaces may form, for example, two sheets, between which the Isoliermateriallage has been inserted or pressed. The standing in contact with the Isoliermateriallage sheets serve as their outer layer and close the air chambers in the cup-shaped recesses and the spaces airtight. The Isoliermateriallage can also be sealed even with one or two outer layers. Due to the connecting webs or walls, no covering layer is necessary on the narrow sides, since the geometry of the layer body already sets a barrier to the air exchange. The material according to the invention is thus well insulating and has relatively low weight.

Die Gestalt der becherförmigen Vertiefungen kann vielfältig sein und ist, wie obenstehend bereits erörtert, keinesfalls auf eine Becherform als solche beschränkt. Ihre Tiefe bzw. die Lagendicke ist dadurch bestimmt, dass eine gewisse Isoliereigenschaft vorhanden sein soll, was ein bestimmtes Luftvolumen notwendig macht. Dieses ist selbstverständlich von der Gestalt der becherförmigen Vertiefungen als solcher unabhängig. Vielmehr kommt es auf das Volumen und die Flächendichte der Luftkammern an. Die Vertiefungen von zweckmäßigen Ausführungen des erfindungsgemäßen Isoliermaterials können polyedrisch, insbesondere wabenartig, sein. Die Vertiefungen anderer Ausführungen weisen eine zumindest bereichsweise gebogene, insbesondere zylindrische, Außenkontur auf. Die becherförmigen Vertiefungen können sich zum Boden hin verjüngen. Auch andere außer den vorbeschriebenen Konturen der Vertiefungen sind möglich. Für eine Abdichtung nach außen sind die Außenlagen notwendig und diese müssen hierzu in ausreichendem Kontakt mit den Verbindungsstegen bzw. -wänden und den "Becherböden" stehen.The shape of the cup-shaped depressions can be varied and, as already discussed above, is by no means limited to a cup shape as such. Their depth or the layer thickness is determined by the fact that a certain insulating property should be present, which makes a certain volume of air necessary. This is of course independent of the shape of the cup-shaped depressions as such. Rather, it depends on the volume and the surface density of the air chambers. The wells of expedient embodiments of the insulating material according to the invention may be polyhedral, in particular honeycomb-like. The recesses of other embodiments have an at least partially curved, in particular cylindrical, outer contour. The cup-shaped depressions can taper towards the bottom. Other than the above-described contours of the wells are possible. For a seal to the outside, the outer layers are necessary and they must be in sufficient contact with the connecting webs or walls and the "cup bases".

Die Gestalt der Verbindungsstege zwischen den Wandungen der Vertiefungen ist durch die Gestalt der Vertiefungen und auch durch die Flächendichte der becherförmigen Vertiefungen bestimmt. Ist die Flächendichte beispielsweise sehr hoch bzw. der Abstand der Wandungen der Vertiefungen sehr klein, ergeben sich beim Formen der Vertiefungen die Verbindungsstege durch geringe zusätzliche Formungsmaßnahmen, weil die Wandungen bei der Bildung der Vertiefungen in Kontakt geraten bzw. gebracht werden. Die Dicke der Verbindungsstege bzw. -wände kann sehr gering sein, da sie im Wesentlichen Barriereeigenschaft haben.The shape of the connecting webs between the walls of the depressions is determined by the shape of the depressions and also by the areal density of the cup-shaped depressions. Is the area density, for example, very high or the distance of the walls of the wells very small, resulting in the molding of the wells, the connecting webs by small additional molding measures, because the walls are in the formation of the wells come into contact or brought. The thickness of the connecting webs or walls can be very small, as they have substantially barrier property.

Wenn die Materiallage des erfindungsgemäßen Isoliermaterials flexibel ausgeführt ist, kann das Isoliermaterial an verschiedene Geometrien des zu isolierenden Gegenstandes angepasst werden.If the material layer of the insulating material according to the invention is made flexible, the insulating material can be adapted to different geometries of the object to be insulated.

Als Außenlage kann vorteilhaft eine Folie, insbesondere Aluminium- oder Polyurethanfolie, auch als selbstklebende Folie, oder ein Vlies, insbesondere Kohlefaservlies, vorgesehen sein. Wie bereits erwähnt, kann die Isoliermateriallage zwischen zwei Elementen leicht gepresst oder mit Kontakt eingebracht werden, wobei eine zusätzliche Außenlage entfällt. Für andere Anwendungen kann bei dem erfindungsgemäßen Isoliermaterial zumindest eine Außenlage eine Furnierlage, eine Platte aus insbesondere Holz, Gips (Rigips), Blech sein.

Die Erfindung wird zunächst anhand von Fig. 1 erläutert. Bei dem dargestellten Ausführungsbeispiel des erfindungsgemäßen Isoliermaterials handelt es sich um einen rechteckförmigen Abschnitt eines faserhaltigen Kunststoffmaterials. Der Isoliermaterialabschnitt kann in dieser Form hergestellt worden sein. Üblicherweise wird er aus einer Endlosbahn des Isoliermaterials abgeschnitten sein. Der Isoliermaterialabschnitt besteht aus einer dünnen Platte 2. Diese enthält in regelmäßiger, dichter Anordnung (Längs- und Querreihen) becher- oder napfartige Vertiefungen 4 mit Zylindergestalt und ebenem Boden 6.The invention will be initially based on Fig. 1 explained. In the illustrated embodiment of the insulating material according to the invention is a rectangular section of a fibrous plastic material. The Isoliermaterialabschnitt may have been made in this form. Usually it will be cut off from an endless track of the insulating material. The Isoliermaterialabschnitt consists of a thin plate 2. This contains in regular, dense arrangement (longitudinal and transverse rows) cup or cup-like depressions 4 with cylindrical shape and flat bottom. 6

Wie die Schnittansicht von Fig. 3 zeigt, ist bei dem vorliegenden Ausführungsbeispiel die Dicke der Platte 2 geringer als die Dicke des Bodens 6. Dies kann aber auch anders sein, z.B. Platte und Boden gleich dick sein.Like the sectional view of Fig. 3 shows, in the present embodiment, the thickness of the plate 2 is smaller than the thickness of the bottom 6. However, this may be different, for example, plate and bottom be the same thickness.

Der Außenwand 8 einer Vertiefung 4 liegen die Außenwände 8 jeweils vier benachbarte Vertiefungen 4 nahebei. Es sind die benachbarten Vertiefungen 4 derselben Längs- und Querreihe. Die Außenwände 8 der Vertiefungen 4 sind jeweils in Richtung der Längs- und Querreihen mit Außenstegen 10 ausgebildet, die sich von der Platte 2 bis zum Boden 6 der Vertiefungen 4 erstrecken. Wie die Schnittansicht von Fig. 3 im linken Teil und auch die perspektivische Ansicht von Fig. 5 zeigt, gehen die Außenstege 10 der Außenwände 8 benachbarter Vertiefungen 4 ineinander über und bilden Verbindungsstege 12, die somit mit den betreffenden Außenwänden 8 einstückig sind, siehe den rechten Teil von Fig. 3. Die durchgehenden Verbindungsstege 12 geben dem Isoliermaterial Formstabilität. Da die Vertiefungen 4 sehr dicht beieinander liegen, sind die Verbindungsstege 12 kurz, wie ebenfalls aus Fig. 3 und 5 ersichtlich ist. Die Verbindungsstege 12 von jeweils zwei benachbarten Vertiefungen 4 aus zwei Quer- und Längsreihen umgrenzen auf der Unterseite der Platte 2 jeweils eine Kammer bzw. einen Hohlraum 14, deren bzw. dessen Boden durch die Platte 2 gebildet wird.The outer wall 8 of a recess 4 are the outer walls 8 each four adjacent depressions 4 nahbei. It is the adjacent recesses 4 of the same longitudinal and transverse rows. The outer walls 8 of the recesses 4 are each formed in the direction of the longitudinal and transverse rows with outer webs 10 extending from the plate 2 to the bottom 6 of the recesses 4. Like the sectional view of Fig. 3 in the left part and also the perspective view of Fig. 5 shows the outer webs 10 of the outer walls 8 of adjacent recesses 4 into each other and form connecting webs 12, which are thus integral with the respective outer walls 8, see the right part of Fig. 3 , The continuous connecting webs 12 give dimensional stability to the insulating material. Since the recesses 4 are very close to each other, the connecting webs 12 are short, as also out Fig. 3 and 5 is apparent. The connecting webs 12 each of two adjacent depressions 4 of two transverse and longitudinal rows on the underside of the plate 2 each define a chamber or a cavity 14, the bottom of which is formed by the plate 2.

Beim veranschaulichten Ausführungsbeispiel ist die Platte 2 aus Kunststoff und die Vertiefungen 4 sind eingepresst worden. Je nach der gewünschten Stabilität bzw. Flexibilität werden die Dicken der Platte 2 und der Außenwände 8 der Vertiefungen 4 und auch die Tiefe der Vertiefungen 4 gewählt. Letztere ist mitbestimmend für das Volumen des in der Platte 2 nach dem Aufbringen der Außenlagen, z.B. Folie, eingeschlossenen Luftvolumens.In the illustrated embodiment, the plate 2 is made of plastic and the recesses 4 have been pressed. Depending on the desired stability or flexibility, the thicknesses of the plate 2 and the outer walls 8 of the recesses 4 and the depth of the recesses 4 are selected. The latter is decisive for the volume of the in the plate 2 after the application of the outer layers, e.g. Foil, trapped air volume.
