Description
Die Erfindung betrifft ein Sandwichelement gemäß dem Oberbegriff des Anspruches 1 sowie ein Verfahren zur Herstellung eines solchen Sandwichelements gemäß Anspruch 8.The invention relates to a sandwich element according to the preamble of claim 1 and a method for producing such a sandwich element according to claim 8.
Ein solches Sandwichelement ist beispielhaft unter der Markenbezeichnung LITECOR® bekannt und weist einen Dreilagenaufbau aus zwei Metalldeckblechteilen und einer zwischengeordneten Kernlage aus Kunststoffmaterial auf.

Die Aufgabe der Erfindung besteht darin, ein Sandwichelement sowie ein Verfahren zur Herstellung eines solchen Sandwichelements bereitzustellen, bei dem das Sandwichelement im Hinblick auf unterschiedliche Einbausituationen funktionell in einfacher Weise erweitert ist.The object of the invention is to provide a sandwich element and a method for producing such a sandwich element, in which the sandwich element is functionally expanded in a simple manner with regard to different installation situations.
Die Aufgabe ist durch die Merkmale des Anspruches 1 oder des Anspruches 8 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The object is solved by the features of claim 1 or claim 8. Preferred developments of the invention are disclosed in the dependent claims.
Die Erfindung geht von einem Sandwichelement mit einem Dreilagenaufbau aus, und zwar bestehend aus zwei Metalldeckblechteilen und einer zwischengeordneten Kernlage aus Kunststoffmaterial. Gemäß dem kennzeichnenden Teil des Anspruches 1 wird die Wärmedämmungsfähigkeit des Sandwichelements fertigungstechnisch einfach sowie bauraumgünstig wie folgt erhöht: So bildet das Kunststoffmaterial der Kernlage des Sandwichelements eine Matrix, in der ein Wärmedämm-Pulver aus hochporösem Feststoff integriert ist. Im Hinblick auf homogene Wärmedämm-Eigenschaften ist es bevorzugt, wenn das Wärmedämm-Pulver homogen bzw. in der Element-Dickenrichtung sowie quer dazu gleichmäßig im Kunststoffmaterial verteilt ist.The invention is based on a sandwich element with a three-layer structure, consisting of two metal sheet metal cover parts and an intermediate core layer made of plastic material. According to the characterizing part of claim 1, the thermal insulation capacity of the sandwich element is increased in terms of production technology and space as follows: The plastic material of the core layer of the sandwich element forms a matrix in which a thermal insulation powder made of highly porous solid is integrated. With regard to homogeneous thermal insulation properties, it is preferred if the thermal insulation powder is distributed homogeneously or uniformly in the element thickness direction and transversely thereto in the plastic material.
Das erfindungsgemäße Sandwichelement besteht aus Deckblechen und einem Kern. Die Deckbleche dienen der Aufnahme von Zug- und Druckkräften, während der Kern die Dichte senken soll und gleichzeitig die Bleche auseinander halten muss, um so das Flächenträgheitsmoment zu erhöhen. Damit das Sandwich allerdings umformbar bleibt und es sich zum Beispiel als Außenblech eignet, wird erfindungsgemäß ein Kernmaterial gewählt, welches isotrope Eigenschaften besitzt (anders als z.B. Schäume). Bevorzugt werden thermoplastische Polymere gewählt. Solche Thermoplasten sind compoundierbar, so dass sich bei der Herstellung des Kunststoffkerns Zusatzstoffe einbringen lassen. Die Einbringung von Aerogelen in den Kern erhöht dabei die Wärmedämmung des Sandwichelements.The sandwich element according to the invention consists of cover sheets and a core. The cover sheets serve to absorb tensile and compressive forces, while the core is intended to reduce density while at the same time keeping the sheets apart in order to increase the area moment of inertia. However, so that the sandwich remains formable and is suitable, for example, as an outer panel, a core material is selected according to the invention which has isotropic properties (unlike foams, for example). Thermoplastic polymers are preferably chosen. Such thermoplastics can be compounded, so that additives can be introduced during production of the plastic core. The introduction of aerogels into the core increases the thermal insulation of the sandwich element.
Der Kern der Erfindung liegt in der Funktionsintegration durch Einbringungen von Aerogelen in den Polymer-Kern. Bisher gibt es solche Ansätze noch nichtfür umformbare Sandwich-Laminate geringer Dicke. Mit der Erfindung sind exemplarisch Außenhaut-Sandwichbleche bereitstellbar, die bei Sonneneinstrahlung einen Wärmeeintrag in das Fahrzeug reduzieren.The core of the invention lies in the integration of functions by introducing aerogels into the polymer core. So far, there are no such approaches for formable sandwich laminates of small thickness. The invention can be used, for example, to provide outer skin sandwich panels that reduce heat input into the vehicle when it is exposed to the sun.
Im Herstellungsprozess der Kunststoff-Kernlage werden Aerogele In das Polymer eingebracht, welches anschließend mit den Metalldeckblechen zu einem Sandwich verarbeitet wird. Dieses Sandwich wird dann, wie auch monolithische Bleche, im Presswerk verarbeitet und fürden Karosseriebau (vor allem Anbauteile) kalt umgeformt und zugeschnitten. Die Verarbeitbarkeit ist im gesamten Prozess ähnliche der von monolithischen Blechen. Durch die Aerogele ist jedoch späterweniger Dämmmaterial notwendig, um den gleichen Komfort zu erreichen. So wird zusätzlich zu der Gewichtseinsparung durch die Verwendung eines Sandwichs weiteres Gewicht durch die Aerogele eingespart.In the manufacturing process of the plastic core layer, aerogels are introduced into the polymer, which is then processed into a sandwich with the metal cover sheets. Like monolithic sheet metal, this sandwich is then processed in the press shop and cold-formed and cut to size for body construction (particularly add-on parts). The workability throughout the process is similar to that of monolithic sheet metal. Due to the aerogels, however, less insulating material is later required to achieve the same level of comfort. Thus, in addition to the weight savings through the use of a sandwich, further weight is saved through the aerogels.
Wenn ebenfalls andere Eigenschaften optimiert werden sollen, gibt es die Möglichkeit auch andere Additive oder Funktionswerkstoffe in den Polymer-Kern einzubringen.If other properties are also to be optimized, there is also the possibility of introducing other additives or functional materials into the polymer core.
In einer nicht von der Erfindung abgedeckten Vergleichsform wird anstelle einer Kunststoff-Kernlage mit Wärmedämm-Pulver aus Festkörper-Partikeln ein Schaumkern gewählt. Die Wärmedämmung wäre auch hier verbessert, jedoch ist die Umformbarkeit nicht mehr gewährleitet. Außerdem muss für den vorgesehenen Anwendungszweck das Sandwich-Laminat sehr dünn sein. Das ist mit einem Schaum kaum zu realisieren. Demgegenüber weist das erfindungsgemäße Sandwichelement folgende Vorteile auf: So sind geringere Dicken möglich. Zudem weist das erfindungsgemäße Sandwichelement bessere Umformeigenschaften auf und ist eine Fertigung im kontinuierlichem Prozess möglich. Darüber hinaus wird die Wärmedämmung ohne Zusatzgewicht erhöht. Zudem fallen ProzessschrittefürdieAnbringung von Dämmmaterial in die Karosserie weg, da dieses nicht mehr oder nur noch teilweise notwendig ist.In a comparative form not covered by the invention, a foam core is selected instead of a plastic core layer with thermal insulation powder made from solid particles. The thermal insulation would also be improved here, but formability is no longer guaranteed. In addition, the sandwich laminate must be very thin for the intended application. This can hardly be realized with a foam. In contrast, the sandwich element according to the invention has the following advantages: Lower thicknesses are possible. In addition the sandwich element according to the invention has better forming properties and production in a continuous process is possible. In addition, the thermal insulation is increased without additional weight. In addition, there are no process steps for attaching insulating material to the body, as this is no longer necessary or only partially necessary.
Nachfolgend werden relevante Erfindungsaspekte nochmals im Einzelnen hervorgehoben: So kann in einer bevorzugten Ausführungsvariante das Wärmedämm-Pulver ein Aerogel-Granulat mit geringer Korngröße sein. Die Korngröße des Wärmedämm-Pulvers kann in einem Bereich zwischen 0,05mm bis 0,1mm liegen. Insbesondere ein Granulat aus Silikat-Aerogel zeigt eine besonders geringe Wärmeleitfähigkeit sowie schalldämmende Eigenschaften. Das Granulat aus Silikat-Aerogel besteht aus hochporösem Festkörper-Partikel, bei denen bis zu 98% des Volumens aus Poren bestehen.Relevant aspects of the invention are highlighted again in detail below: In a preferred embodiment variant, the thermal insulation powder can be an airgel granulate with a small grain size. The grain size of the thermal insulation powder can range from 0.05mm to 0.1mm. In particular, a granulate made of silicate airgel shows particularly low thermal conductivity and sound-insulating properties. The granules of silicate airgel consist of highly porous solid particles, in which up to 98% of the volume consists of pores.
In einer technischen Umsetzung ist es im Hinblick auf die Erzielung von isotropen Eigenschaften besonders bevorzugt, wenn die Kernlage des Kunststoffmaterials komplett schaumfrei ist und lediglich das Wärmedämm-Pulver darin integriert ist. Das Kunststoffmaterial der Kernlage kann in einer technischen Umsetzung ein Polymer, insbesondere Biopolymer, sein. Die Metalldeckblechteile können aus Stahl gefertigt sein. Bei einer Anwendung des Sandwichelements speziell im Automobilbereich ist es bevorzugt, wenn das Sandwichelement eine Element-Dicke im Bereich von 0,6mm bis 2mm aufweist. In diesem Fall können die Metalldeckblechteile eine Dicke von 0,15mm bis 0,4mm aufweisen, während die Kunststoffkernlage eine Dicke von 0,3mm bis 1,2mm aufweist.In a technical implementation, with a view to achieving isotropic properties, it is particularly preferred if the core layer of the plastic material is completely foam-free and only the thermal insulation powder is integrated into it. In a technical implementation, the plastic material of the core layer can be a polymer, in particular a biopolymer. The metal cover sheet parts can be made of steel. When the sandwich element is used specifically in the automotive sector, it is preferred if the sandwich element has an element thickness in the range from 0.6 mm to 2 mm. In this case, the metal cover sheet parts can have a thickness of 0.15mm to 0.4mm, while the plastic core layer has a thickness of 0.3mm to 1.2mm.
Das Sandwichelement bildet ein Halbzeug, das unter Kaltumformung weiterverarbeitbar ist. Bevorzugt kann das Sandwichelement zu einem Außenhautteil und/oder zu einem Karosserie-Strukturteil weiterverarbeitet werden, beispielhaft als Dach, Tür, Heckklappe oder Motorhaube.The sandwich element forms a semi-finished product that can be further processed by cold forming. The sandwich element can preferably be further processed into an outer skin part and/or into a body structural part, for example as a roof, door, tailgate or hood.
Das erfindungsgemäße Sandwichelement kann bevorzugt wie folgt hergestellt werden: So kann zunächst eine Kunststoff-Ausgangskomponente unter Einwirkung von Druck und Wärme (zum Beispiel in einem Extruder) aufgeschmolzen und mit dem Wärmedämm-Pulver zu einer schmelzflüssigen Masse durchmischt werden. Aus der schmelzflüssigen Masse kann, zum Beispiel durch Kalandrierung oder Extrusion, eine Folienbahn erzeugt werden, die in einer Wickelstation aufwickelbar ist. In einer prozesstechnisch nachgeschalteten Kaschiervorrichtung können zwei Metall-Endlosbahnen unter Zwischenordnung der Folien-Endlosbahn unter Druck und Wärme zu einer Verbundmaterial-Endlosbahn verbunden werden. Die Verbundmaterial-Endlosbahn kann in einer prozesstechnisch nachgeschalteten Schneidstation zu dem Sandwichelement abgelenkt werden.The sandwich element according to the invention can preferably be produced as follows: First, a plastic starting component can be melted under the action of pressure and heat (for example in an extruder) and mixed with the thermal insulation powder to form a molten mass. A film web can be produced from the molten mass, for example by calendering or extrusion, which can be wound up in a winding station. In a laminating device downstream of the process technology, two continuous metal webs can be connected under pressure and heat to form a continuous web of composite material with the continuous web of film being arranged in between. The continuous web of composite material can be deflected to form the sandwich element in a downstream cutting station.
In einer technischen Umsetzung kann das Kunststoffmaterial der Kernlage ein Polymer, insbesondere ein Biopolymer, sein. Die Metalldeckblechteile können aus Stahl gefertigt sein.In a technical implementation, the plastic material of the core layer can be a polymer, in particular a biopolymer. The metal cover sheet parts can be made of steel.
