Description

Die Erfindung betrifft eine graphithaltige Platte nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zur Herstellung einer graphithaltigen Platte.The invention relates to a graphite-containing plate according to the preamble of claim 1 and to a method for producing a graphite-containing plate.

Aus der DE 103 41 255 B4 ist eine Leichtbau-Wärmeleitplatte sowie ein Verfahren zu deren Herstellung bekannt. Diese Wärmeleitplatte wird aus an sich bekanntem expandierten Graphit (Graphitexpandat) durch Verdichtung hergestellt. Die Herstellung von expandiertem Graphit ist aus dem Stand der Technik hinlänglich bekannt, u. a. aus der US 3,404,061 A . So werden zur Herstellung von expandiertem Graphit Graphiteinlagerungsverbindungen bzw. Graphitsalze wie z. B. Graphithydrogensulfat oder Graphitnitrat schockartig erhitzt. Dabei vergrößert sich das Volumen der Graphitpartikel um einen Faktor von ca. 200–400 und gleichzeitig sinkt die Schüttdichte auf Werte von 2–20 g/l. Das so erhaltene Graphitexpandat besteht aus wurm- bzw. ziehharmonikaförmigen Aggregaten. Bei der Leichtbau-Wärmeleitplatte der DE 103 41 255 B4 wird derartiges Graphitexpandat unter gerichteter Einwirkung eines Drucks kompaktiert, so dass sich die Schichtebenen des Graphits bevorzugt senkrecht zur Einwirkungsrichtung des Drucks anordnen und sich die einzelnen Aggregate untereinander verhaken. Hierdurch lassen sich ohne Zusatz von Bindemitteln selbsttragende, flächige Gebilde wie Bahnen oder Platten herstellen. Solchermaßen kompaktierte Wärmeleitplatten ohne Bindemittel sind zwar grundsätzlich formstabil, weisen jedoch eine geringe Festigkeit auf, brechen also bei relativ geringen Belastungen leicht auseinander. So weisen beispielsweise rechteckige Wärmeleitplatten mit einem Flächengewicht von 1000 g/m2, einer Dicke von 13 mm und der Größe 11 × 13 cm lediglich eine Biegefestigkeit von 0,1 MPa auf. Es können deshalb lediglich formstabile Platten mit relativ geringen Abmessungen, z. B. 50 × 50 cm hergestellt werden, da größere Platten nicht mehr handhabbar sind. Insbesondere führt bereits das Eigengewicht größerer Platten dazu, dass die Platte beim Anhaben an nur einer Seitenkante bricht. Diese Platten sind deshalb für die Verwendung im Baubereich ohne zusätzliche Versteifungen nicht geeignet.From the DE 103 41 255 B4 is a lightweight heat conduction and a process for their preparation is known. This heat conduction plate is made of known per se expanded graphite (Graphitexpandat) by compaction. The production of expanded graphite is well known from the prior art, including from US 3,404,061 A , Thus, for the production of expanded graphite Graphiteinlagerungsverbindungen or graphite salts such. B. graphite hydrogen sulfate or graphite nitrate shock-heated. The volume of the graphite particles increases by a factor of about 200-400 and at the same time the bulk density drops to values of 2-20 g / l. The graphite expandate thus obtained consists of worm-shaped or accordion-shaped aggregates. In the lightweight thermal plate of DE 103 41 255 B4 If such Graphitexpandat is compacted under the direction of a pressure, so that the layer planes of the graphite preferably arranged perpendicular to the direction of action of the pressure and the individual units interlock with each other. As a result, self-supporting, flat structures such as webs or plates can be produced without the addition of binders. Such compacted heat conducting plates without binders are basically dimensionally stable, but have a low strength, so they break apart easily at relatively low loads. For example, rectangular heat conducting plates having a weight per unit area of 1000 g / m 2 , a thickness of 13 mm and a size of 11 × 13 cm only have a bending strength of 0.1 MPa. It can therefore only dimensionally stable plates with relatively small dimensions, for. B. 50 × 50 cm are made because larger plates are no longer manageable. In particular, even the weight of larger plates to the fact that the plate breaks when it touches on only one side edge. These panels are therefore not suitable for use in the construction sector without additional stiffeners.

Um diesen Nachteil zu überwinden, schlägt die DE 103 41 255 B4 vor, die Wärmeleitplatten nach dem Verpressen komplett oder teilweise mit Kunststoffen, beispielsweise Harzen oder Thermoplasten zu imprägnieren, um die Dichtigkeit und die Beständigkeit gegen mechanische und andere Umwelteinwirkungen zu erhöhen. Diese nachträgliche Flüssigimprägnierung der verpressten Graphitexpandatplatten weist jedoch den Nachteil auf, dass die Infiltration des expandierten, verdichteten Graphits mit den flüssigen Bindemitteln ungleichmäßig erfolgt. So wurde bereits bei Folien aus verdichtetem expandiertem Graphit festgestellt, dass sie lediglich in oberflächennahen Bereich gleichmäßig infiltriert werden. In weiter innen liegende Bereiche der Folien dringt das Bindemittel nur noch unzureichend oder gar nicht ein. Gleiches gilt in noch stärkerem Maß für die gegenüber Folien deutlich dickeren Platten aus verdichtetem expandiertem Graphit. Diese ungleichmäßige Verteilung des Bindemittels führt zu einer ungleichmäßige Steifigkeit und Stabilität der Platten, so dass die Platten an von außen nicht erkennbaren Stellen leichter brechen als an anderen.To overcome this disadvantage, the beats DE 103 41 255 B4 prior to impregnation, the heat-conducting plates completely or partially impregnate with plastics, such as resins or thermoplastics in order to increase the tightness and resistance to mechanical and other environmental effects. However, this subsequent liquid impregnation of the compressed Graphitexpandatplatten has the disadvantage that the infiltration of the expanded, compacted graphite is carried out unevenly with the liquid binders. For example, it has already been found in films of compressed expanded graphite that they are uniformly infiltrated only in the area close to the surface. In more interior areas of the films penetrates the binder only insufficient or not at all. The same applies to an even greater extent for the sheets of thicker expanded graphite, which are significantly thicker than foils. This uneven distribution of the binder results in uneven stiffness and stability of the panels, such that the panels break more easily at locations not recognizable from outside than at others.

In 1 ist ein schematischer Querschnitt durch eine derartige Leichtbau-Wärmeleitplatte 1 gezeigt. Dort ist verpresster, expandierter Graphit 2 von den Seitenflächen der Platte 1 aus nachträglich mit einem flüssigen Bindemittel 3 infiltriert worden. Das Bindemittel 3 ist jedoch nur ungleichmäßig in die Platte eingedrungen, so dass insbesondere ein durch die ovale, gestrichelte Umrandung gekennzeichneter Bereich 4 bindemittelfrei 3 und somit deutlich weniger steif und stabil als angrenzende Bereiche der Platte 1 ist. Dieser Bereich 4 ist somit bruchgefährdeter als die angrenzenden Bereiche der Platte 1.In 1 is a schematic cross section through such a lightweight heat conduction plate 1 shown. There is compressed, expanded graphite 2 from the side surfaces of the plate 1 subsequently with a liquid binder 3 been infiltrated. The binder 3 However, it has only unevenly penetrated into the plate, so that in particular a marked by the oval, dashed border area 4 binder-free 3 and thus significantly less stiff and stable than adjacent areas of the plate 1 is. This area 4 is thus more vulnerable to breakage than the adjacent areas of the plate 1 ,

Es ist deshalb Aufgabe der Erfindung, eine graphithaltigen Platte und ein Verfahren zur Herstellung einer graphithaltigen Platte bereitzustellen, welche die oben genannten Nachteile überwinden und eine gleichmäßig steife und formstabile Platte bereitstellen.It is therefore an object of the invention to provide a graphite-containing plate and a method for producing a graphite-containing plate, which overcome the above-mentioned disadvantages and provide a uniformly rigid and dimensionally stable plate.

Diese Aufgabe wird durch eine graphithaltigen Platte mit den Merkmalen des Anspruchs 1 sowie ein Verfahren zur Herstellung einer graphithaltigen Platte mit den Merkmalen des Anspruchs 10 gelöst. Vorteilhafte Weiterbildungen und bevorzugte Ausgestaltungen der Platte und des Verfahrens sind in den Unteransprüchen angegeben.This object is achieved by a graphite-containing plate having the features of claim 1 and a method for producing a graphite-containing plate having the features of claim 10.

Für höhere Ansprüche können vorteilhaft Phenolharze verwendet werden, ebenso auch Melaminharz, Harnstoffharze und Polyester-Harze, insbesondere ungesättigte Polyester-Harze (UP-Harze).A suitable thermoset is preferably epoxy resin, which is widely used, easy to process, relatively inexpensive and temperature resistant. Phenol resins can advantageously be used for higher demands, as well as melamine resin, urea resins and polyester resins, in particular unsaturated polyester resins (UP resins).

Auch kann die Verfestigung einen Schmelz- und einen Abkühlschritt umfassen, um beispielsweise Thermoplaste teilweise oder vollständig aufzuschmelzen. Hierdurch lässt sich eine gute Verbindung zwischen Graphitpartikeln und Kunststoffpartikeln erzielen. Insbesondere bei der Verwendung von Duroplasten kann die Verfestigung einen Aushärteschritt umfassen. Auch kann die Verfestigung durch eine alternative oder zusätzliche Sinterung des Gemischs erfolgen.Preferably, the solidification of the mixture by compression, in particular by means of compression, take place. Also, the solidification may include a melting and a cooling step to partially or completely melt, for example, thermoplastics. This makes it possible to achieve a good bond between graphite particles and plastic particles. In particular, when using thermosets, the solidification may include a curing step.

Anschließend kann die Platte dann am Einbauort endverfestigt werden, beispielsweise durch Erhitzen der noch plastisch verformbaren Platte im eingebauten Zustand.In an advantageous embodiment, the plate is plastically deformable, so that it can be easily molded at the installation site to predetermined contours of walls or ceilings of rooms, such as edges, bends, corners, friezes, etc. Subsequently, the plate can then be finally solidified at the installation site, for example by heating the still plastically deformable plate in the installed state.

Für die vorteilhafte Verwendung der erfindungsgemäßen Platte als Wand- oder Deckenverkleidung und/oder als thermisch wirksames Bauelement zur Kühlung oder Heizung von Räumen kann das Gemisch zunächst so vorfestigt werden, dass es plastisch verformbar bleibt.

Weitere Besonderheiten und Vorzüge der Erfindung ergeben sich aus der folgenden Beschreibung von bevorzugten Ausführungsbeispielen anhand der Zeichnungen. Es zeigen:Other features and advantages of the invention will become apparent from the following description of preferred embodiments with reference to the drawings. Show it:

Eine in 2 dargestellte erfindungsgemäße graphithaltige Platte 5 besteht aus Graphitpartikeln 6 aus expandiertem Graphit, welche in bekannter Weise wurm- oder ziehharmonikaförmig sind. Anstelle von expandiertem Graphit kann auch Naturgraphit oder synthetischer Graphit, bevorzugt in Pulverform, verwendet werden. Expandierter Graphit weist jedoch den Vorteil auf, dass es sich einerseits gut zu einer dichten, in geringem Umfang formstabilen Platte verpressen lässt und andererseits gut mit festen Kunststoffpartikeln 7 vermischbar ist.An in 2 illustrated graphite-containing plate according to the invention 5 consists of graphite particles 6 of expanded graphite, which in known worm or accordion-shaped. Instead of expanded graphite, natural graphite or synthetic graphite, preferably in powder form, can also be used. However, expanded graphite has the advantage that it can be pressed well on the one hand to a dense, to a small extent dimensionally stable plate and on the other hand well with solid plastic particles 7 is miscible.

Die Graphitpartikel 6 werden zunächst mit den festen Kunststoffpartikeln 7, hier PVC, weitgehend gleichmäßig vermischt. Dies kann in bekannter Weise durch an sich bekannte Mischvorrichtungen für pulverförmige Materialien erfolgen. Die Graphitpartikel 6 werden dabei weitgehend gleichmäßig, also vorteilhafterweise mindestens zu 85%, mit den Kunststoffpartikeln 7 vermischt, um eine möglichst gleichmäßig stabile Platte 5 zu erhalten. Bevorzugt werden die Partikel 6, 7 homogen miteinander vermischt.The graphite particles 6 be first with the solid plastic particles 7 , here PVC, largely uniformly mixed. This can be done in a known manner by per se known mixing devices for powdery materials. The graphite particles 6 be largely uniform, so advantageously at least 85%, with the plastic particles 7 mixed to a stable as evenly stable plate 5 to obtain. The particles are preferred 6 . 7 homogeneously mixed together.

Nach dem Vermischen werden wird das Gemisch in bekannter Weise durch Druckeinwirkung zur Platte 5 verpresst. Um die Bindung zwischen den Kunststoffpartikeln 7 untereinander und mit den Graphitpartikeln 6 zu erhöhen, wird das Gemisch zusätzlich erhitzt, so dass die Kunststoffpartikel 7 anschmelzen oder sogar ganz aufschmelzen, dann untereinander verschmelzen und sich mit den Graphitpartikeln verbinden. In einem Kühlvorgang, der durch aktive Kühlung oder passive Abkühlen des Gemischs erfolgen kann, erstarren die aufgeschmolzenen Kunststoffpartikel 7 unter Beibehaltung ihrer geschmolzenen Form, so dass eine gleichmäßig formstabile Platte 5 erhalten wird.After mixing, the mixture is in a known manner by pressure to the plate 5 pressed. To the bond between the plastic particles 7 with each other and with the graphite particles 6 To increase, the mixture is additionally heated so that the plastic particles 7 melt or even completely melt, then merge together and connect with the graphite particles. In a cooling process, which can be done by active cooling or passive cooling of the mixture, solidify the molten plastic particles 7 while maintaining its molten shape, leaving a uniformly dimensionally stable plate 5 is obtained.

Die beiden oben genannten Schritte – Verpressen und Erhitzen – können auch hintereinander durchgeführt werden. Alternativ oder auch zusätzlich kann die Verfestigung bzw. Verdichtung auch durch Aushärten und/oder Sintern erfolgen. Auch lassen sich diese unterschiedlichen Arten der Verfestigung miteinander kombinieren.The two steps mentioned above - pressing and heating - can also be carried out in succession. Alternatively or additionally, the solidification or compression can also be effected by curing and / or sintering. Also, these different types of consolidation can be combined.

Durch die erfindungsgemäße Vermischung der Graphitpartikel 6 und der Kunststoffpartikel 7 zu einem Gemisch mit weitgehend gleichmäßiger Verteilung der Partikel vor der Verfestigung kann eine gegenüber den bekannten graphithaltigen Platten 1 vorteilhafte gleichmäßige über ihre Fläche formstabile, steife, robuste und leicht handhabbare Platte 5 hergestellt werden.By the inventive mixing of the graphite particles 6 and the plastic particles 7 to a mixture with a substantially uniform distribution of the particles before solidification can be compared to the known graphite-containing plates 1 advantageous uniform over its surface dimensionally stable, rigid, robust and easy to handle plate 5 getting produced.

Gleiche Teile werden mit den gleichen Bezugszeichen versehen wie in 2.Preferably show examples of use of the plate according to the invention and the manufacturing method according to the invention 3 and 4 , The same parts are provided with the same reference numerals as in 2 ,

3 zeigt die erfindungsgemäße vorteilhafte Verwendung einer erfindungsgemäßen Platte 5 als thermisch wirksames Bauelement in Form einer Decken-/Wandverkleidungsplatte zur Heizung und/oder Kühlung eines Raumes. Hierbei wurden nach dem Vermischen der Graphitpartikel 6 und der Kunststoffpartikel 7, aber vor dem Verfestigen dieses Gemischs, zwei Leitungsrohre 8 mittig in das Gemisch eingebracht. Nachfolgend wurde dann das Gemisch wie oben beschrieben endverfestigt. Hierdurch lassen sich auf einfache Weise vorkonfektionierte und für die Verwendung als Heiz- und/oder Kühlelement vorbereitete Wandverkleidungsplatten herstellen, so dass eine Fertigung derartiger Platten sowie ihre Verwendung im Baubereich in industriellem Maßstab durchgeführt werden kann. Aufgrund der großen Formstabilität und Steifigkeit derartiger Platten wird die Handhabung und Montage der Platten im Baustellenbereich erleichtert, insbesondere können auch formstabile Platten mit größeren Abmessungen hergestellt und verwendet werden, ohne eine Beschädigung der Platten bei Transport und Handhabung befürchten zu müssen. 3 shows the advantageous use according to the invention of a plate according to the invention 5 as a thermally active component in the form of a ceiling / wall cladding panel for heating and / or cooling a room. In this case, after mixing, the graphite particles 6 and the plastic particles 7 but before solidifying this mixture, two pipes 8th introduced centrally into the mixture. Subsequently, the mixture was finally solidified as described above. As a result, can be prepared in a simple way prefabricated and prepared for use as heating and / or cooling element wall cladding panels, so that a production of such plates and their use in the construction sector can be carried out on an industrial scale. Due to the great dimensional stability and rigidity of such plates, the handling and assembly of the plates in the construction site area is facilitated, in particular dimensionally stable plates can be made and used with larger dimensions without having to fear damage to the plates during transport and handling.

Eine solche Platte mit eingebetteten Leitungsrohren 8 kann bspw. in einer Einrichtung zur Temperierung eines Raumes verwendet werden, wobei die Einrichtung wenigstens ein Bauelement, wie z. B. eine Betondecke oder -wand, welches einen thermischen Speicher bildet und eine in den Raum weisende Oberfläche aufweist und wobei die Leitungsrohre 8 mit dem thermischen Speicher gekoppelt und mit einem Heiz- oder Kühlmedium beaufschlagbar sind.Such a plate with embedded pipes 8th can be used, for example, in a device for controlling the temperature of a room, wherein the device is at least one component, such as. B. a concrete ceiling or wall, which forms a thermal storage and having a surface facing in the space and wherein the conduits 8th coupled with the thermal storage and can be acted upon by a heating or cooling medium.

Eine solche Einrichtung zur Temperierung eines Raumes ermöglicht es, die Masse der Decken oder Wände als thermischer Speicher zu nutzen, ohne dass Rohrleitungen zur Durchleitung eines Heiz- oder Kühlmediums zur thermischen Aktivierung des Speichers in die Decken oder Wände eingebracht werden müssen. Dadurch wird ein energieeffizientes Temperiersystem mit kurzen Ansprechzeiten bereit gestellt, welches darüber hinaus auch bei der Sanierung von Altbauten nachträglich eingebaut werden kann.Such a device for controlling the temperature of a room makes it possible to use the mass of the ceilings or walls as a thermal storage without pipes must be introduced for the passage of a heating or cooling medium for thermal activation of the memory in the ceilings or walls. This provides an energy-efficient temperature control system with short response times, which can also be retrofitted to refurbish old buildings.

4 zeigt die erfindungsgemäße vorteilhafte Verwendung einer erfindungsgemäßen Platte 5 als thermisch wirksames Bauelement in Form einer Decken-/Wandverkleidungsplatte zur Heizung und/oder Kühlung eines Raumes. Hierbei wurden im Gegensatz zu der Ausführung in 3 nach dem Vermischen der Graphitpartikel 6 und der Kunststoffpartikel 7, das Gemisch zunächst so vorverfestigt, dass es noch plastisch verformbar ist, und erst dann zwei Leitungsrohre 9 in die plastisch verformbar Platte 5 eingedrückt und nachfolgend die Platte 5 bzw. das Gemisch endverfestigt, wie oben beschrieben. Bei der Ausführung nach 4 ergeben sich die Vorteile wie bei der Ausführung nach 3. 4 shows the advantageous use according to the invention of a plate according to the invention 5 as a thermally active component in the form of a ceiling / wall cladding panel for heating and / or cooling a room. This was in contrast to the execution in 3 after mixing the graphite particles 6 and the plastic particles 7 , the mixture first pre-consolidated so that it is still plastically deformable, and only then two pipes 9 in the plastically deformable plate 5 pressed in and subsequently the plate 5 or the mixture finally solidified, as described above. In the Execution after 4 the advantages arise as in the execution 3 ,

In einer Weiterbildung der Platte 5 aus 4 kann diese vorteilhaft zunächst bei der Fertigung plastisch verformbar vorverfestigt, anschließend zum Einsatzort, beispielsweise einer Baustelle, transportiert und erst dort die Leitungsrohre 9 an geeigneten Stellen in die Platte 5 eingedrückt werden. Anschließend wird die Endverfestigung vor Ort durchgeführt, beispielsweise durch Erhitzen der noch plastisch verformbaren Platte 5 in bereits eingebautem Zustand. Hierdurch kann die Verlegung der Leitungsrohre 9 einfach an die speziellen Gegebenheiten vor Ort angepasst werden.In a further development of the plate 5 out 4 This can advantageously first pre-consolidated plastically deformable during manufacture, then transported to the site, such as a construction site, and only there the pipes 9 in suitable places in the plate 5 be pressed. Subsequently, the final consolidation is carried out on site, for example by heating the still plastically deformable plate 5 in already installed condition. As a result, the laying of the pipes 9 easily adapted to the specific conditions on site.
