Abstract

Thermoplastic facing layers(06) and thermoplastic foam beads(03) are welded onto a thermoplastic honeycombed supporting core(02) to form a unified panel. Foam beads(05) immediately adjoining the facing layers(06) are melted during pressing to give a density similar to that of the facing layers. Welded joints(07) between the core ribs(02) and the facing layers also have the same density as the facing layers. The density and welding intensity of core and foam beads between the facing layers decreases towards the panel center. A single heating and cooling process joins all layers together. A sheet material(01) can be embedded in the facing layers and can be perforated or have countersunk holes facing either towards or away from the facing layers. Facing layers form a smooth surface to the panel. The panel is completely recyclable and the plastic material can be regranulated. Foam beads filling spaces between the honeycomb ribs absorb little or no moisture, are weather, chemical and ageing resistant and have good abrasion and wear resistance. Good heat insulation and resilience are dependent on the foam bead density. Beads are unaffected by nails or screws and depression created by screwing or nailing recover rapidly. Panel surfaces do not adhere to concrete and can be easily repaired by welding using a similar plastic. Surfaces are also UV(ultra-violet) resistant. Finished panels have similar strength and bending characteristics to plywood without the problem of moisture pick-up. Panels can be sawn and edge strips of the same material can be welded on or added in the pressing process. Alternative cores may be formed by top hat sections, tubes, box sections or corrugations. An independent claim is included for a process for manufacturing the claimed panel in which: a) a heaped filling of foam beads(03) is introduced into a thermoplastic core(02); b) sheet materials(01) with or without perforations or countersunk holes are placed on the upper and lower sides; c) the assembly is then heated and pressed before cooling to give a final panel with a smooth, depressed or raised surface which may include additional features such as formed edges and holes, grooves, suspension attachments, reinforcements and other inserts.

Description

Leichte Verbundplatten mit einem Waben- oder Schaumkern, mit Deckschichten aus Kunststoff, Metall- oder Laminatschichten verschiedener Art sind bekannt. Auch solche, bei denen die thermo- oder duroplastischen Deckschichten glas- oder kohlefaserverstärkt, aufgeklebt oder aufgeschweißt und der Wabenkern Phenol- oder PU-Schaumgefüllt sind.light Composite panels with a honeycomb or foam core, with cover layers made of plastic, metal or laminate layers of various kinds are known. Even those in which the thermosetting or thermosetting Top layers glass or carbon fiber reinforced, glued or welded and the honeycomb core Phenolic or PU foam filled are.

Diese Platten dienen in einfacher Ausführung als Paneele oder Einlegeböden für Fahrzeuge, als leichte Bodenplatten und seit kurzer Zeit auch als Gerüstbelag oder, mit extra starken und schweren Deckschichten und einem schweren Schaumkern als Schalungsplatte. Letztere sind notwendig, um solche Schalungsplatten schnittfest und nagelbar zu machen, was bei diesen Platten absolut erforderlich ist.These Plates serve in a simple design as panels or shelves for vehicles, as light floor slabs and, for a short time, also as scaffold flooring or, with extra strong and heavy cover layers and a heavy one Foam core as formwork panel. The latter are necessary to such formwork panels cut-firm and nailbar, what with these plates absolutely is required.

Um eine überdurchschnittliche Wärmedämmfähigkeit für die Platte herzustellen, wird diese auch schon mit Phenol- oder PU-Schaum im Wabenkern gefüllt, was dann zum Beispiel bei Platten mit Waben aus Thermoplast dazu führt, daß diese nicht mit Thermoplastdeckschichten verschweißt werden können.Around an above-average thermal performance for the Plate, this is already with phenolic or PU foam filled in honeycomb core, What then for example with plates with honeycombs made of thermoplastic leads, that these can not be welded with thermoplastic cover layers.

Ein weiteres Erfordernis ist, daß sich im Kern der Platte bei Beschädigungen der Deckschicht in der Schaumschicht keine Feuchtigkeit festsetzt und beim Durchnageln keine Krater auf der Rückseite aufbrechen. Durch die bekannten Herstellungsverfahren können leichte Verbundplatten mit sämtlichen notwendigen Eigenschaften jeweils in mehreren Arbeitsgängen und zu erheblichen Kosten im Heiß- oder Kalt-Preßverfahren hergestellt werden.One Another requirement is that in the core of the plate in case of damage the cover layer in the foam layer does not set any moisture and do not break craters on the back when nailing. By the known manufacturing processes can be lightweight composite panels with all necessary Properties in each case in several operations and at considerable cost in the hot or Cold-pressing process getting produced.

Bei der Herstellung einer schaumgefüllten Platte mit PP-Wabenkern muß zum Beispiel zuerst die Wabe im Extrusions-Verfahren hergestellt, auf die notwendige Plattenstärke beschnitten und dann durch Einschäumen oder Eindrücken gleich dicker Schaumplatten die Wabe verfüllt und dann ein Polyestervlies durch Tränken mit PP aufgeschweißt oder auf den leicht überstehenden Schaumkern aufgeklebt werden. Erst danach kann die jeweilige Verklebung weiterer PP-, GfK- oder Metall-Schichten erfolgen.at the production of a foam-filled plate with PP honeycomb core must to First, the honeycomb produced by extrusion, on the necessary plate thickness cut and then by foaming or pressing the same thick foam sheets filled the honeycomb and then a polyester fleece by watering welded with PP or on the slightly protruding Foam core are glued. Only then can the respective bonding Further PP, GfK or metal layers take place.

Schalungsplatten aus PP, die eine harte Oberfläche und eine hohe Biegefestigkeit haben müssen, werden mit Deckschichten aus Metall oder Fasern zu Kunststoffverbund-Konstruktionen aufgebaut, um das erforderliche E-Modul und die Außenfläche aus dem nichthaftenden PP zu erreichen, so daß hier zum Beispiel ein sehr hohes Gewicht, ähnlich dem sonst verwendeten Sperrholz, einen Teil des Nutzens der Langlebigkeit wieder aufwiegt, so daß weder durch geringeres Gewicht ein leichteres Arbeiten mit der Platte, noch die durch mehrfache Produktionsdurchgänge erforderlichen hohen Kosten eine preisliche Akzeptanz möglich ist.Formboards made of PP, which has a hard surface and have to have a high flexural strength, be with topcoats made of metal or fibers to composite plastic constructions, around the required modulus of elasticity and the outer surface of the non-adhesive PP to achieve, so here For example, a very high weight, similar to the otherwise used Plywood, recovers part of the benefits of longevity, so that neither lighter weight makes it easier to work with the plate, nor the high costs required by multiple production runs a price acceptance possible is.

Erfindungsgemäß wurde deshalb die Aufgabe gestellt, eine besonders leichte, oberflächenharte, nagelbare, nichthaftende, witterungsbeständige, wärmedämmende, recyclbare, leicht reparierbare, abrieb- und kratzfeste Platte mit der mechanischen Festigkeit und dem Biegeverhalten üblicher Sperrholzplatten, nicht jedoch mit deren Quellverhalten in Metallrahmen und dem deshalb erforderlichen Mindermaß in trockenem Zustand zu entwickeln, die in den Herstellungskosten günstig durch die Einsparung mehrerer Arbeitsgänge in möglichst einem einzigen Heiß- und Kühlpreßgang auf die erforderliche Gesamtstärke thermisch verschweißt werden kann.According to the invention was Therefore, the task is a very light, surface-hardened, nailable, non-adhesive, weather-resistant, heat-insulating, recyclable, easy to repair, abrasion and scratch resistant plate with the mechanical strength and the bending behavior usual Plywood boards, but not with their swelling behavior in metal frames and to develop the required reduction in dry condition, the low in the cost by saving several operations in as possible a single hot and Kühlpreßgang the required total strength thermally welded can be.

Dazu wurde auf Verfahren wie zum Beispiel nach der Patentanmeldung PCT WO 03/083352 A2 aufgebaut, bei denen verschiedene Deckschichten, wie glasfaserverstärktes Polypropylen oder Senkloch- und/oder geprimertes Blech mit Polypropylenplatten und Polypropylenwaben sich thermisch fest verschweißen, jedoch mit dem erfindungsgemäßen, zusätzlichen Einbinden eines losen Polypropylen-Perlschaums entsprechenden Raumgewichts in die Wabenröhrchen und zwar so, daß dieser sich an den verschweißten Verbindungsstellen des Deckschichtverbunds mit dem perlschaumgefüllten Stützkern unter dem zeit- und temperaturgesteuerten Druck in der Heißpresse verschweißt und an den Schweißkanten in einer gewünschten Dichte, Stärke und Festigkeit beim Abkühlen dauerhaft und fast schwindungsfrei stabilisiert.To was based on methods such as the patent application PCT WO 03/083352 A2 constructed in which various cover layers, such as glass fiber reinforced Polypropylene or Senkloch- and / or primed sheet with polypropylene plates and polypropylene honeycomb thermally welded, however with the invention, additional Incorporation of a loose polypropylene pearl foam corresponding weight per unit area in the honeycomb tubes in such a way that this to the welded ones Connecting points of the cover layer composite with the pearl foam filled support core below the time and temperature controlled pressure in the hot press welded and at the welding edges in a desired Density, strength and Firmness on cooling stabilized permanently and almost without shrinkage.

Dieses Verfahren ermöglicht es in einem einzigen Heiß- und Kühlpreßgang, durch einfaches Auflegen der erforderlichen Schichten, zuerst der unteren Deckschichten in einer gewünschten Reihenfolge auf einer stabilen Trennschicht zur unteren Pressplatte hin, dann der Wabe in der für die Plattenendstärke erforderlichen Stärke, dem Auffüllen der Wabe und Einrütteln von PP-Perlen entsprechender Größe sowie dem weiteren Aufschichten solchen Materials auf die ose gefüllte Wabe für die Erzeugung der später erforderlichen Verstärkung und Veränderung des Raumgewichts durch die Preßhitze und den Preßdruck an den Verbindungsstellen, sowie dem abschließenden Auflegen der oberen Deckschichten in der gewünschten Reihenfolge mit der darübergelegten Tennschicht zur oberen Preßplatte hin, in einem Paket die Schichten heiß so zu verschweißen und durch Druck und Hitze und spätere Abkühlung so zu verändern, daß eine einwandfreie leichte Verbundplatte mit einem vorher vorgegebenen Gewicht und Aufbau entsteht.This Procedure allows it in a single hot and Kühlpreßgang, through easy laying on of the required layers, first of the lower ones Cover layers in a desired Order on a stable release layer to the lower press plate down, then the honeycomb in the for the plate thickness required strength, the padding the honeycomb and shaking of PP beads of appropriate size as well the further layering of such material on the ose filled honeycomb for the Generation of the later required reinforcement and change the weight of the space through the heat of pressing and the pressing pressure at the joints, as well as the final laying of the upper Cover layers in the desired Order with the above Tennschicht to the upper press plate in a package to heat the layers so hot and through Pressure and heat and later Cooling to change that way that one perfect light composite panel with a previously given Weight and structure arise.

Eine solche leichte Kunststoff-Verbund-Hartplatte hat die Eigenschaften einer metallarmierten PP-Platte genauso wie einer glasfaserarmierten Hartschaumplatte mit extrem hohem Gesamt-Raumgewicht, nicht jedoch die Nachteile hohen Gewichts und hoher Materialkosten, da in der Mitte der wenig beanspruchten Stützkernhöhe, wo lediglich die die Wabenstege bestimmende Steghöhe die statisch erforderlichen Werte liefern, ein geringes Perlschaumgewicht mit hoher Wärmedämmung vorhanden ist, was dazu führt, daß das Gesamtraumgewicht der Materialschichten nur in den äußeren Deckschichten vorhanden ist, und zwar zur Plattenmitte hin in abnehmendem Maße durch das durch den abnehmenden Temperaturfluß geringer werdende Aufschmelzen des Perlschaummaterials.A Such lightweight plastic composite hardboard has the characteristics a metal-reinforced PP plate as well as a fiberglass-reinforced foam board with extremely high total density, but not the disadvantages of high weight and high material costs, because in the middle of the little stressed support core height, where only the honeycomb webs determining ridge height provide the statically required values, a low pearl foam weight with high thermal insulation available is what causes that this Total weight of the material layers only in the outer layers available is, and towards the center of the plate to a decreasing extent the melting which decreases as a result of the decreasing temperature flow of the pearl foam material.

Wichtig ist noch, daß die Platten in fast jeder erforderlichen Stärke und Größe und mit einer Vielfalt der erforderlichen Eigenschaften in bezug auf Biegesteifigkeit, Schlagzähigkeit, Raumgewicht und Oberfläche gleichermaßen in der Auslegungsfläche einer Presse entsprechenden Längen und Breiten in einem Pressengang, ja sogar mit der Kombination einer Waben-Extrudieranlage mit einer Doppelbandpresse im kontiuierlich ablaufenden Verfahren hergestellt werden können, so daß durch die Großflächigkeit und Einfachheit der Herstellung besondere Wirtschaftlichkeit sichergestellt ist.Important is still that the Plates in almost every size and size required and with a variety of properties required with respect to flexural strength, impact resistance, Density and surface equally in the design area a press corresponding lengths and widths in a press section, even with the combination of a honeycomb extruder with a double-belt press are produced in kontiuierlich expiring process can, so that through the large area and Simplicity of production ensured special economy is.
