Abstract

The method produces laminated magnetic panels, a magnetic plastic sheet being coated on both sides with adhesive such as melamine. A layer of cardboard is placed on one side, and one of decorative paper on the other. The assembly is then heated to approximately 170 deg.C and pressed together with a pressure of between 50 and 500 tons per sq. metre, until they are permanently secured together. One or more of the layers can be pre-heated before assembly. Iron filings can be scattered between the sheet and the cardboard and/or paper.

Description

Verfahren zum Herstellen von Platten Method of making panels

Die Erfindung betrifft das Herstellen von aus mehreren Schichten bestehenden magnethaftenden Platten und das daraus hergestellte Erzeugnis nämlich eine Platte.The invention relates to the manufacture of multiple layers magnetic disks and the product made therefrom, namely a disk.

Eine Platte der gattungsgemäßen Art ist beispielsveise durch die DE-OS 2 248 773 bekanntgevorden. Die Platte weist eine äußere Feinschicht auf, die aus einer Mischung von Magnetpulver, Hartholzpulver und Bindemittel besteht.A plate of the generic type is for example by the DE-OS 2 248 773 became known. The plate has an outer fine layer that consists of consists of a mixture of magnetic powder, hardwood powder and binding agent.

Ein Furnier, bestehend aus mindestens drei miteinander verbundenen Folien, ist durch das DE-Gbm 72 10 513 bekanntgeworden. Die mittlere Folie besteht aus einem Bindemittel, in das Eisen eingebettet ist. Nachteilig hierbei ist die teuere Fertigung und die relativ geringe Haftkraft. Bekannt sind weiter dekorative Beschichtungen von Holzverkstoffen mit kunstharzimprägniertem Papier; siehe Goldschmiedt informiert ..., 4, 1969, Nr. 9, Seite 3 bis 9 und aus dem Buch Dekorative Schichtstoffplatten" von Oskar H. Steinmetz, DRW-Verlags-GmbH, Stuttgart, Seite 13 sind Plattentypen bekanntgeworden, die imprägniert sind z.B. beschichtetes Sperrholz usw.A veneer consisting of at least three joined together Films, has become known through DE-Gbm 72 10 513. The middle slide is made from a binder in which iron is embedded. The disadvantage here is expensive production and the relatively low adhesive force. Decorative ones are also known Coatings of wood-based materials with paper impregnated with synthetic resin; see goldsmith informs ..., 4, 1969, No. 9, p 3 to 9 and from the book Decorative Laminate panels "by Oskar H. Steinmetz, DRW-Verlags-GmbH, Stuttgart, page 13 types of panels have become known which are impregnated, e.g. coated plywood etc.

Aufgabe der Erfindung ist es, eine Platte zu erstellen, die äußerst preiswert und optimal haftend, bei vielfältiger Verwendbarkeit, ist.The object of the invention is to create a plate that extremely inexpensive and optimally adheres, with a wide range of uses.

Gelöst wird die gestellte Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1 und Anspruch 3 sowie die der tkiteransprüche.The task at hand is solved by the characteristic features of claim 1 and claim 3 as well as those of the kiteboarding claims.

Weitere Einzelheiten ergeben sich aus der schematischen Darstellung einer Platte in Teilansicht.Further details can be found in the schematic representation of a plate in partial view.

Die Platte besteht aus einer Dekorpapierschicht 1 und einer Pappe 3; zwischengefügt ist eine Magnetfolie 2 aus Kunststoff. Im Herstellungsverfahren wird mindestens eine der aufeinanderzubringenden Flächen mit einem Kleber z.B.The plate consists of a decorative paper layer 1 and a cardboard 3; A magnetic sheet 2 made of plastic is interposed. In the manufacturing process at least one of the surfaces to be joined with an adhesive e.g.

Melamin beschichtet (oder beide zu gegeneinanderlegenden Flächen), dann wird das "Paket" erhitzt; das Erhitzen kann aber auch schon beim Aufeinanderlegen beginnen. Das Erhitzen erfolgt in einem Bereich um ca. 1700C (nicht zwingend) und dann wird unter einem sehr hohen Druck, vorzugsweise von 100 bis 500 Tonne. bezogen auf eine Fläche von einem Quadratmeter das ganze Paket solange zusammengepreßt, bis es zu einer einheitlichen Platte zusammengefügt ist, d.h. alle Materialien sind unlösbar miteinander verbunden.Melamine coated (or both surfaces facing each other), then the "package" is heated; however, heating can also occur when laying them on top of each other kick off. The heating takes place in a range around 1700C (not mandatory) and then under a very high pressure, preferably from 100 to 500 ton. the whole package based on an area of one square meter compressed until it is assembled into a unitary plate, i.e. all Materials are inextricably linked.

Das Erstaunliche hierbei ist, daß der Magnetismus der Magnetfolie trotz des Druckes und trotz des Erhitzens nach dem Abkühlen praktisch voll erhalten bleibt. So erhält man eine Platte, die auf der einen Seite eine sehr dünne Schicht eines Dekorpapiers (beispielsweise) zeigt. Die Steifigkeit der Platte wird vor allem durch die Pappschicht gewährleistet, besser gesagt durch das "Verbacken" der einzelnen Schichten zu einem Paket.The amazing thing here is that the magnetism of the magnetic sheet in spite of the pressure and in spite of the heating obtained after cooling practically full remain. So you get a plate that has a very thin layer on one side a decorative paper (for example) shows. The rigidity of the plate is mainly guaranteed by the cardboard layer, better said by the "baking" of the individual Layers in a package.

Als Magnetfolie findet ein bekannter Werkstoff Verwendung, also ein flexibler Dauerhaftmagnet, bestehend aus pulverförmigem Dauermagnetuerkstoff und einem gummiartigen flexiblen Bindemittel; der Dauermagnetwerkstoff soll eine möglichst hohe toerzitivkraft haben und die magnetisierte Fläche soll vorzugsweise aus einer Vielzahl von Polen abvechselnder Polarität bestehen. Als Dauermagnetwerkstoff kommt insbesondere Bariumferrit in Frage. Diese und ähnliche "tunststoffmagnete" sind an sich bekannt und jede Art dieser Magnete kann hier Verwendung finden. Somit ist die Anvendung solcher bekannten flexiblen kunststoffgebundenen Magnete für den vorgesehenen Zweck ebenfalls als erfinderisch anzusehen. Die Korngröße des Dauermagnetwerkstoffes soll möglichst gering sein z.B. 0,3 mm oder noch sehr viel kleiner.A well-known material is used as the magnetic film, i.e. a flexible permanent magnet, consisting of powdery permanent magnet material and a rubbery flexible binder; the permanent magnet material should be as possible have high toerzitivkraft and the magnetized surface should preferably consist of a There are multitudes of poles of alternating polarity. Comes as a permanent magnet material especially barium ferrite. These and similar "plastic magnets" are known per se and any type of these magnets can be used here. So is the Use of such known flexible plastic-bonded magnets for the intended The purpose is also to be regarded as inventive. The grain size of the permanent magnet material should be as small as possible, e.g. 0.3 mm or much smaller.

Die Platte ist für die verschiedensten Zvecke verwendbar wie z.B. als Lagerschilder (beschriftbar), Groschenhalter (Musterhalter, Schrauben, Nägel) etc., Messestandblenden (metallbeschichtete Buchstaben und Schilder), Zeichenbretter, magnetische Schultafeln, Spiel- und Mustertafeln, Tabletts, Armaturenbretter, Sperren oder Bänder, die Metallspäne absondern, Förderplatten, Transportvagen, Schalldämpfung, Planungstafeln (mit kleinen Blechteilen), Musterkoffer als Grundplatte, Kurstafeln, Tafeln für Preisauszeichnung, Ladenbau, Wände, Schachspiele (Mühle, Dame etc.), Schilder, Möbelflächen, Schulungstafeln, Flipchart, Liedertafeln, Halteplatten (Schrauben etc.), arcEtektonische Planungwände, Trainertafeln, Einbauwände, Trennwände, Schulungswände, Bildwände etc.The plate can be used for a wide variety of purposes such as as bearing plates (can be labeled), penny holders (sample holders, screws, nails) etc., exhibition stand panels (metal-coated letters and signs), drawing boards, magnetic school boards, game and sample boards, trays, dashboards, locks or belts that secrete metal chips, conveyor plates, transport trolleys, soundproofing, Planning boards (with small sheet metal parts), sample case as a base plate, course boards, Boards for price labeling, shop fitting, walls, chess games (mill, checkers etc.), Signs, furniture surfaces, training boards, flipcharts, song boards, retaining plates (screws etc.), arcectonic planning walls, coaching boards, built-in walls, partition walls, training walls, Picture walls etc.

Es gehört weiter zur Erfindung, daß beispielsweise auf der anderen Seite der Pappe 3, also spiegelbildlich, auch eine Magnetfolie 2 und darauf ein Dekor- oder anderes Papier aufgebracht werden kann.It is also part of the invention that, for example, on the other Side of the cardboard 3, so mirror image, also a magnetic sheet 2 and on it Decorative or other paper can be applied.

Um die Haftkraft zu erhöhen, kann Eisenpulver zvischengefügt werden. Die Beschichtung mit einem Bindemittel erfolgt hier sinngemäß wie vorher im einzelnen beschrieben.To increase the adhesive force, iron powder can be added. The coating with a binding agent is carried out here analogously as before in detail described.

Statt der Pappe kann auch ein anderes Trägermaterial z.B. Sperrholz, eine Kunststoffplatte oder dgl. Verwendung finden.Instead of cardboard, another carrier material, e.g. plywood, a plastic plate or the like. Use.
