Description
PaneelPanel
Die Erfindung betrifft ein Paneel, welches aus einer Kernschicht und wenigstens einer damit stofflich verbundenen äußeren Decklage besteht.The invention relates to a panel which consists of a core layer and at least one outer cover layer materially connected thereto.
Derartige Paneele könnten auch als Platten oder Tafeln bezeichnet werden, die für die verschiedensten Verwendungszwecke geeignet sind. Bei dem in Rede stehenden Paneel handelt es sich um einen Schichtenverbund aus geeigneten Kunststoffen. Im Normalfall ist die mittlere Kernschicht beidseitig durch je eine Decklage abgedeckt.Such panels could also be referred to as boards or panels, which are suitable for a wide variety of uses. The panel in question is a layered composite made of suitable plastics. Normally, the middle core layer is covered on both sides by a cover layer.
Zum Transport von verderblichen Lebensmitteln sind Kühlfahrzeuge notwendig, wobei je nach Art des Fahrzeuges einzelne Kammern auch auf Minustemperaturen für Gefriergut heruntergekühlt werden müssen. Zur Lagerung derartiger Lebensmittel sind gekühlte Räume oder Kühlhäuser erforderlich. Die Wände von Kühlräumen oder Kühlhäusern werden mit geeigneten, thermisch isolierenden Materialien ausgeschlagen. Ein äußerst bekanntes Material ist das sog. Styropor. Die tragenden Teile von Kühlfahrzeugen sind im Normalfall aus Metall, vorzugsweise aus Stahl hergestellt. Da es sich dabei um äußerst gut thermisch leitende Materialien handelt, werden sie mit Platten ausgeschlagen, die aus einem thermisch isolierendenRefrigerated vehicles are necessary for the transport of perishable foodstuffs, whereby, depending on the type of vehicle, individual compartments may also have to be cooled down to sub-zero temperatures for frozen goods. Refrigerated rooms or cold stores are required for the storage of such foodstuffs. The walls of cold stores or cold stores are lined with suitable, thermally insulating materials. One very well-known material is so-called Styrofoam. The load-bearing parts of refrigerated vehicles are normally made of metal, preferably steel. Since these are extremely good thermal conductors, they are lined with panels made of a thermally insulating material.

Material bestehen. Gleiches gilt auch fur Kühlgeräte, beispielsweise Kühlschränke, Gefriergeräte u.dgl.material. The same applies to cooling devices, such as refrigerators, freezers, etc.
Als besonders nachteilig hat sich herausgestellt, daß die bislang verwendeten thermisch isolierenden Materialien nur durch geringe mechanische Kräfte belastet werden können. Außerdem nehmen sie Feuchtigkeit auf, wodurch die thermisch isolierende Wirkung herabgesetzt wird, so daß ggf. weitere Maßnahmen notwendig werden können. Darüber hinaus sind die derzeit eingesetzten thermischen isolierende Materialien sehr spröde bzw. die Schlagfestigkeit ist äußerst gering.It has been found that the thermally insulating materials used to date can only withstand low mechanical forces. They also absorb moisture, which reduces the thermally insulating effect, so that further measures may be necessary. In addition, the thermally insulating materials currently used are very brittle and have extremely low impact resistance.
Der Erfindung liegt die Aufgabe zugrunde, ein Paneel bzw. eine Platte oder eine Tafel der eingangs näher beschrieben Art so zu gestalten, daß die thermisch isolierende Wirkung voll erhalten bleibt, daß jedoch insbesondere die mechanische Belastbarkeit erhöht wird.The invention is based on the object of designing a panel or a plate or a board of the type described in more detail at the outset in such a way that the thermally insulating effect is fully retained, but in particular the mechanical load-bearing capacity is increased.
Die gestellte Aufgabe wird gelöst, indem der Grundwerkstoff für das Paneel ein Polyolefin ist, vorzugsweise Polypropylen ist, daß die Kernschicht aus einem Polyolefinschaum (Polypropylen und/oder Polyethylen) besteht und daß in jede äußere Decklage wenigstens eine Gewebelage eingebettet ist. Wesentlich ist die Ausführung der Zellstruktur des Schaums derart, daß die Oberfläche des Schaums oder der Schaum als ganzes das Eindingen von Feuchtigkeit verhindert. Dies wird durch die Vermeidung von Poren zwischen den Zellen des Schaums erreicht. Der Schaum kann hierbei offen- oder geschlossenzellig sein, vernetzt oder unvernetzt.The task is solved by the base material for the panel being a polyolefin, preferably polypropylene, the core layer being made of a polyolefin foam (polypropylene and/or polyethylene) and at least one fabric layer being embedded in each outer cover layer. It is important that the cell structure of the foam is designed in such a way that the surface of the foam or the foam as a whole prevents moisture from penetrating. This is achieved by avoiding pores between the cells of the foam. The foam can be open-cell or closed-cell, cross-linked or non-cross-linked.
Die Kunsstoffgruppe der Polyolefine wird bereits für viele hoch beanspruchte technische Teile verwendet. Die für die Verwendung in Kühlfahrzeugen und Kühlgeräten notwendige thermische Isolierung ist voll ausreichend. Gegenüber den bisher bekannten thermisch isolierenden Materialien ist jedoch die Belastbarkeit bzw. die Schlagfestigkeit wesentlich größer, wobei Polypropylen bessere mechanische Werte aufweist. Besonders bevorzugt wird Polypropylen jedoch für Haushaltsgeräte u.dgl. verwendet. Außerdem wurde Polypropylen mit Textilien und anderen dekorativenThe group of plastics known as polyolefins is already used for many highly stressed technical parts. The thermal insulation required for use in refrigerated vehicles and refrigerators is completely sufficient. However, compared to the thermally insulating materials known to date, the load-bearing capacity and impact resistance are significantly higher, with polypropylene having better mechanical properties. However, polypropylene is particularly preferred for household appliances and the like. In addition, polypropylene has been combined with textiles and other decorative materials.

Materialien beschichtet. Darüber hinaus wurden Seile, Filter, Netze, Garne sowie Kunstrasen aus Polypropylen hergestellt. Da nunmehr der Kern aus einem wasserdichten Polyolefinschaum besteht, wird die thermische Isolierung noch erhöht. Da die Decklagen bzw. die Decklage nunmehr mindestens eine Gewebelage aufweist, kann die mechanische Belastbarkeit, insbesondere die Schlagfestigkeit so weit erhöht werden, daß aus dem erfindungsgemäßen Paneel Aufbauten für Nutzfahrzeuge hergestellt werden können. Da das Gewicht des Aufbaues noch wesentlich gegenüber den bekannten Konstruktionen herabgesetzt wird, kann die Nutzlast eines Nutzfahrzeuges bei gleichem zulässigen Gesamtgewicht erhöht werden. Außerdem besteht der Vorteil, daß bei Verwendung des Paneels keine Wärme oder Kältebrükken entstehen. Dadurch wird beispielsweise bei der Verwendung als Aufbau für ein Kühlfahrzeug entweder die Temperatur im Inneren des Aufbaus herabgesetzt oder die Leistung des Kühlaggregates kann in vorteilhafter Weise herabgesetzt werden. Das Gewebe der Decklagen kann aus den verschiedensten Materialien bestehen, wobei jedoch eine ausreichend hohe mechanische Belastbarkeit erforderlich ist. In bevorzugter Ausführung werden doch ein Glasfaser- oder ein Fasermaterial verwendet, welches in einem Material der Polyoleflngruppe, vorzugsweise Polypropylen eingebettet ist. Die Decklagen und die mittlere Kernschicht werden zunächst in getrennten Verfahren hergestellt und anschließend thermisch zusammengeführt. Die Maschenweite des Gewebes ist gering, so daß die Einbettung der sich kreuzenden Fäden oder Stäbe auch wie eine Ummantelung mittels des Kunststoffes Polypropylen zu sehen ist.Materials coated. In addition, ropes, filters, nets, yarns and artificial turf were made from polypropylene. Since the core now consists of a waterproof polyolefin foam, the thermal insulation is even better. Since the cover layers or the cover layer now has at least one fabric layer, the mechanical load-bearing capacity, in particular the impact resistance, can be increased to such an extent that superstructures for commercial vehicles can be made from the panel according to the invention. Since the weight of the superstructure is significantly reduced compared to known designs, the payload of a commercial vehicle can be increased with the same permissible total weight. There is also the advantage that no heat or cold bridges are created when the panel is used. This means that, for example, when used as a superstructure for a refrigerated vehicle, either the temperature inside the superstructure is reduced or the performance of the refrigeration unit can be advantageously reduced. The fabric of the cover layers can be made of a wide variety of materials, although a sufficiently high mechanical load-bearing capacity is required. In a preferred embodiment, a glass fiber or fiber material is used which is embedded in a material from the polyolefin group, preferably polypropylene. The cover layers and the middle core layer are initially produced in separate processes and then thermally combined. The mesh size of the fabric is small, so that the embedding of the crossing threads or rods can also be seen as a sheathing using the plastic polypropylene.
Anhand der beiliegenden Zeichnungen wird die Erfindung noch näher erläutert. Es zeigen:The invention is explained in more detail with reference to the accompanying drawings. They show:
Figur 1 das erfindungsgemäße Paneel im Querschnitt und Figur 2 eine Decklage im Längsschnitt.Figure 1 shows the panel according to the invention in cross section and Figure 2 shows a cover layer in longitudinal section.
Das in der Figur 1 dargestellte Paneel 10 ist ein Schichtenverbund, der aus drei Schichten besteht, nämlich der inneren Kernschicht 11 und zwei äußeren DecklagenThe panel 10 shown in Figure 1 is a layered composite consisting of three layers, namely the inner core layer 11 and two outer cover layers

12. Die innere Kernschicht 11 besteht aus einem wasserdichten Polyolefinschaum, so daß die thermische Isolierung sehr hoch ist. Die beiden Decklagen 12 sind mit mindestens einer Gewebelage 13 ausgestattet, die entweder in die Decklage 12 aus Polypropylen eingebettet ist oder deren sich kreuzende Fäden oder Drähte sind mit Polypropylen ummantelt. Durch diese Gewebematte 13 wird die mechanische Belastbarkeit des Paneels wesentlich beeinflußt, so daß das Paneel zur Herstellung von Gebäudewänden oder von Wänden von Fahrzeugaufbauten verwendet werden kann. Es entstehen keine Wärme- oder Kältebrücken, da das Paneel als eine Vollkunststoffplatte angesehen werden kann, obwohl das Gewebe 13 aus geeigneten Werkstoffen herstellt werden kann. Bevorzugt kommen jedoch Glasfasern in Frage. Die Figur 2 zeigt das Gewebe 13 in vergrößerter Ausführung. Die Maschenweite des Gewebes 13 ist relativ gering, so daß die Außenfläche jeder Decklage 13 noch als glattflächig angesehen werden kann, selbst wenn die sich kreuzenden Fäden oder Drähte mit Polypropylen ummantelt sind. Gemäß der Darstellung nach der Figur 2 sind die Abstände zwischen den sich kreuzenden Fäden oder Drähten gleich. Entgegen dieser Darstellung könnten sie auch ungleich sein. Durch die geringe Dichte des Polyolefinschaums und durch das niedrige Flächengewicht der Decklagen 12 ist das Gewicht des Paneels pro Flächeneinheit äußerst gering ist.12. The inner core layer 11 consists of a waterproof polyolefin foam, so that the thermal insulation is very high. The two cover layers 12 are equipped with at least one fabric layer 13, which is either embedded in the cover layer 12 made of polypropylene or whose crossing threads or wires are covered with polypropylene. This fabric mat 13 has a significant influence on the mechanical load-bearing capacity of the panel, so that the panel can be used to make building walls or walls of vehicle bodies. No thermal or cold bridges are created, since the panel can be considered a solid plastic panel, although the fabric 13 can be made of suitable materials. However, glass fibers are preferred. Figure 2 shows the fabric 13 in an enlarged version. The mesh size of the fabric 13 is relatively small, so that the outer surface of each cover layer 13 can still be considered to be smooth, even if the crossing threads or wires are covered with polypropylene. According to the representation in Figure 2, the distances between the crossing threads or wires are equal. Contrary to this representation, they could also be unequal. Due to the low density of the polyolefin foam and the low weight per unit area of the cover layers 12, the weight of the panel per unit area is extremely low.
Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt. Wesentlich ist, daß die mittlere Kernschicht aus einem wasserdichten Polyolefinschaum besteht, und daß die äußeren Decklagen jeweils wenigstens eine Gewebelage beinhalten.The invention is not limited to the embodiment shown. What is important is that the middle core layer consists of a waterproof polyolefin foam and that the outer cover layers each contain at least one fabric layer.
