Dreidimensional strukturierte Schaumatoffplatte oder Schaumstoffblocks Verfahren zu deren Herstellung, sowie Vorrichtung zur Durchfiihrung des Verfahrens.Three-dimensionally structured foam board or foam blocks Process for their production and device for carrying out the process.
Dreidimensional strukturierte Schaumstoffplatten und Schaumstoffblöcke d.h. Schaumstoffplatten oder Schaumstoffblöcke, die zumindest auf einer Plattenoberfläche bzw. Blockoberfläche Erhebungen und Vertiefungen aufweisen, werden bisher aus thermoplastischen Kunststoffschäumen, in der Regel auf der Basis von Polystyrol, (Polyurethan) oder Polyvinylchlorid nach dem Stand der Technik derart hergestellt, daß man die schäumungsfähige lasse in solchen Formen ausschäumt, deren innenseitige flache Begrenzungswand bzw. Begrenzungswände die entsprechenden dreidimensionalen Positivstrukturen aufweisen, wodurch dann die fertige Schaumstoffplatte bzw. der fertige Schaumstoffblock die jeweilige Negativstruktur besitzt.Three-dimensionally structured foam sheets and foam blocks i.e. foam sheets or blocks of foam resting on at least one sheet surface or block surface have elevations and depressions, have so far been made of thermoplastic Plastic foams, usually based on polystyrene, (polyurethane) or Polyvinyl chloride produced according to the prior art in such a way that the foamable foam in molds whose inner flat boundary wall or Boundary walls have the corresponding three-dimensional positive structures, whereby then the finished foam board or the finished foam block die has the respective negative structure.
Naturgemäß sind diese bisher bekannten Verfahren zur Herstellung von dreidimensional strukturierten Schaumstoffplatten bzw. Blöcken sehr aufwendig, da die flachseitigen Begrenzungsfläohen der Formen zunächst einmal strukturiert hergestellt werden müssen, was bei den bekannten, ohnehin hohr Kosten der Formenherstellung einen weiteren stark verteuernden i?aktor darstellt.Naturally, these previously known processes for the production of three-dimensionally structured foam sheets or blocks are very expensive because the flat-sided boundary surfaces of the forms are first of all produced in a structured manner will must, what with the known, already high costs of mold production another highly expensive i? aktor represents.
Demgegenüber bezieht sich vorliegende Erfindung auf eine dreidimensional strukturiet Schaumstoffplatte bzw. einen dreidimensional strukturierten Schaumstoffblock, die ohne Verwendung von entsprechend strukturierten Formen geschaffen sind. Diese neue Schaumstoffplatte bzw. Block sind dadurch gekennzeichnet, daß zumindest eine plattenoberfläche bzw. Blockoberfläche Bereiche aufweist, die durch gegebenenfalls verschmorendes Einschmelzen tiefer liegen, als die stehengebliebenen erhabenen Restbereiche. Der fertigen dreidimensional strukturierten Schauinstoffplatte bzw.In contrast, the present invention relates to a three-dimensional structured foam board or a three-dimensionally structured foam block, which are created without the use of appropriately structured shapes. These new foam board or block are characterized in that at least one plate surface or block surface has areas that may be through charring melts lie deeper than the remaining raised areas. The finished three-dimensionally structured display panel or
Block ist vom Fachmann ohne weiteres anzusehen, daß sie aus einer Schaumstoffplatte bzw. Schaurnstoffblock mit zuvor planen Oberflächen dadurch gewonnen wurde, daß durch Einwirkung von Hitze und Druck ein Einschmelzen gewisser Bereiche geschaffen wurde. Bei diesem EinschmeLzvorgang fallen gewisse oder auch grosse Bereiche des Schaumstoffs, gegebenenfalls unter leichtem Yerschmoren in sich zusammen, so daß dieser Vorgang nicht twa mit einem Prägevorgang verglichen werden kann.Block can be seen by the person skilled in the art without further ado that it consists of a Foam board or foam block with previously planar surfaces obtained in this way became that by the action of heat and pressure a melting down of certain areas was created. During this melting process, certain or even large areas fall of the foam, if necessary with light simmering together, like this that this process cannot be compared with a stamping process.
Nach einer bevorzugten Ausführungsform eines Hertellungsverfahrens für die erfindungsgemäße dreidimensional strukturierte Schaumstoffplatte bzw. Block wird derart gearbeitet, daß man in fertige Schaumstoffplatten bzw. Blöcke gewtinschter Stärke mittels einer entsprechend positiv strukturierten und geheizten Metallgußplatte oder Metallgußwalze unter geringem Druck die gewünschte Struktur "hineinpreßt". Bekanntlioh bestehen beispielsweise Polystyrolplatten aus fast 97 % Poren, wobei beim erfindungsgemäßen Verfahren die restlichen 3 P Polystyrolmasse praktisch weggeschmolzen werden.According to a preferred embodiment of a manufacturing process for the three-dimensionally structured foam sheet or block according to the invention is worked in such a way that one wtinschter in finished foam sheets or blocks Strength by means of a correspondingly positively structured and heated cast metal plate or a metal cast roller "presses in" the desired structure under low pressure. For example, polystyrene panels are known to consist of almost 97 % Pores, with the remaining 3 P polystyrene mass in the process according to the invention are practically melted away.
Nach einer besonderen Ausführungsform ist diese geheizte strukturierte Netallgußplatte bzw. die strukturierte geheizte Walze mit einem Trennmittel, wie beispielsweise PolytetrafluorEthylen beschichtet und bis auf die Schmelztemperatur des jeweiligen Schaumstoffs erhitzt. Beim Eindrücken der erhitzten strukturierten Preßplatte bzw. Preß-Walze wird also die jeweilige Struktur aus dem Schaumstoff herausgeschmolzen mit dem Ergebnis, daß die Oberfläche der Sohaumstoffplatte die entsprechende und gewünsohte Negativstruktur aufweist.According to a particular embodiment, this is heated and structured Netallgußplatte or the structured heated roller with a release agent such as for example polytetrafluoroethylene coated and down to the melting temperature of the respective foam is heated. When pressing the heated textured The respective structure of the foam is thus the press plate or press roller melted out with the result that the surface of the foam board the has corresponding and desired negative structure.
Nach dem erfindun5gemäßen Verfahren kann man sowohl einals auch zweiseitige strukturierte Schaumstoffplattcn für alle möglichen sinnvollen Zwecke preisgünstiger und wesentlich rascher herstellen, als dies beim oben beschriebenen Verfahren des Standes der Technik jemals mögl ch ist.According to the method according to the invention, both one-sided and two-sided structured foam panels for all sorts of useful purposes cheaper and produce much faster than in the above-described method of the State of the art is ever possible.
Die erfindungsgemäßen Erhebungen und Vertiefungen aufweisenden, d.h. dreidimensional strukturierten Sohaumstoffplatten bzw. Blöcke eignen sich beispielsweise hervorragend dazu, entsprechend strukturierte gegossene Betonflächen, bzw. Aussenflächen von Beton-Stützmauern oder Beton-Häuserfassaden zu gießen. Dieses Gießverfahren zur Herstellung von strukturierten Betonflächen wird dabei derart ausgeführt, daß an den Innenwänden der Schalungen die erfindungsgemäßen dreidimensional strukturierten Schaumstoffplatten angeordnet werden und anschließend die zu gießende Betonmasse zur Einfüllung kommt. Nach deren Erhärten wird auf die übliche Weise ausgeschalt, wobei nach einmaligem Gebrauch die erfindungsgemäßen strukturierten Schaumstoffplatten weggeworfen werden können. Zum Zwecke der Vermeidung einer unerwünschten Adhäsion zwischen der Betongußmasse und der Oberfläche der strukturierten Schaumetoffplatten können letztere mit an sich bekannten, beispielsweise hydrophoben Mitteln präpariert sein.The elevations and depressions according to the invention, i. three-dimensionally structured foam sheets or blocks are suitable, for example excellent for this, appropriately structured poured concrete surfaces or outside surfaces pouring concrete retaining walls or concrete house facades. This casting process for the production of structured concrete surfaces is carried out in such a way that the three-dimensionally structured according to the invention on the inner walls of the formwork Foam panels are arranged and then the concrete mass to be poured comes to the filling. After hardening it will open the usual way switched off, the structured according to the invention after a single use Foam sheets can be thrown away. For the purpose of avoiding an undesirable Adhesion between the concrete casting compound and the surface of the structured foam panels the latter can be prepared with known, for example hydrophobic, agents be.
Eine weitere Anwendung der erfindungsgemäßen dreidimensiol nal strukturierten Schaumstoffplatten besteht in deren Benutzung als Deckenplatte mit beliebiger Struktur filr Räume, wobei diese Deckenplatte beispielsweise neben ihrer Flächenstruktur noch zusätzlich eine modische Einfärbung aufweisen kann.Another application of the three-dimensionally structured according to the invention Foam panels consist in their use as a ceiling panel with any structure for rooms, with this ceiling tile, for example, in addition to its surface structure can also have a fashionable coloring.
Die erfindungsgemäßen dreidimensional strukturierten Schaumstoffblöcke lassen sich beispielsweise als, wohlfeile Verpackungen verwenden.The three-dimensionally structured foam blocks according to the invention can be used, for example, as inexpensive packaging.
Das Wesen vorliegender Erfindung wird nun anhand der beiliegenden Figuren 1 d8 3, die idiglich einige der möglochen Ausführungsformen zeigen, weiterhin erläutert.The essence of the present invention will now be based on the accompanying FIGS. 1 to 8 3, which only show some of the possible embodiments, continue explained.
Figur 1 stellt also die erfindungsgemäße, Erhebungen und Vertiefungen aufweisende, d.h. dreidimensional strukturierte Schaumstoffplatte, die das Bezugezeichen 1 trägt, dar.Figure 1 thus represents the invention, elevations and depressions having, i.e. three-dimensionally structured foam sheet, which has the reference symbol 1 carries.
Figur 2 zeigt eine Variation des Herstellungsverfahrens und Figur 3 eine weitere Variation des Verfahrens.FIG. 2 shows a variation of the manufacturing process and FIG 3 another variation of the method.
Die erfindungsgemäße dreidimensional strukturierte Sohaumetoffplatte 1 der Figur Ig weist also bei dieser AuefUhrungsform auf der Oberseite die Erhebungen 2 und Vertiefungen 3 auf, wobei in diesem Fall Erhebungen und Vertiefungen eine relativ reguläre Struktur aufweisen. Selbstverständlich können sowohl die Erhebungen als auch die Vertiefungen völlig individuell jeweils einmalig und beliebig hoch bzw. beliebig tief, also insgesamt gesehen irregulär gestattet sein, je nach der Gestaltung der Oberfläche des Preß- und Ileizelements, das zur Anwendung gelangt. Mit dem Bezugszeichen 4 ist der unverändert gebliebene Plattenteil, der in der Regel den grösseren Anteil ausmacht bezeichnet. An den Begrenzungslinien 5 zwischen den erhabenen und vertieften Bereichen sind im allgemeinen letollte Sohmorkanten oder Schmorgrate vorhanden, deren dunklere Färbung und sonstige Beschaffenheit die Anwendung von Wärme erkennen läßt. Die Anwendung von geringeren oder stärkerem Druck ist durch die Strukturverformung ohne weiteres zu erkennen.The three-dimensionally structured carbon foam sheet according to the invention 1 of the figure Ig thus shows in this embodiment on the top the elevations 2 and 3 depressions, in this case elevations and depressions have a relatively regular structure. Of course, both the surveys as well as the indentations completely individual, each unique and of any height or arbitrarily deep, i.e. seen as a whole irregularly, depending on the Design of the surface of the pressing and sealing element that is used. With the reference numeral 4 is the unchanged plate part, the rule denotes the greater part. At the boundary lines 5 between the Raised and recessed areas are generally hollow edges or Braising present, their darker color and other texture the application from warmth reveals. The application of less or more pressure is through to recognize the structural deformation easily.
Figur 2 zeigt die oben erwähnte Metallgußplatte 6, deren Unterfläche die erhabenen Bereiche 3a und die dazwischenliegenden nicht erhabenen Bereiche 2a aufweist. Es ist leicht einzusehen, daß das lierabführen der durch die Ileizstrahler 7 erwärmten Metallgußplatte 6, die mit den Stempel 8 einstückig verbunden und durch diesen geführt ist und damit eine Art Stempelpresse bildet, auf die glattseitige Schaumstoffplatte, vorzugsweise Polystyrolpiatte Ja, die auf einer Unterlage 9 ruht, in der Lage ist, in der Schaumstoffplatte eine egativstruktur gegenüber der Positivstruktur der beheizten Metallgußplatte zu erzeugen d.h. es entstehen die vertieften Bereiche 3 unter Stenenbleiben der erhabenen Bereiche 2, womit dann die erfindungsgemaß dreidimensional strukturierte Schaumstoffplatte entstanden ist.Figure 2 shows the above-mentioned cast metal plate 6, its lower surface the raised areas 3a and the intervening non-raised areas 2a having. It is easy to see that the drainage is carried out by the heat emitters 7 heated cast metal plate 6, which is integrally connected to the punch 8 and through this is guided and thus forms a kind of punch press on the smooth side Foam board, preferably polystyrene board Yes, which rests on a base 9, is able to have a negative structure in the foam board compared to the positive structure the heated metal casting plate, i.e. the recessed areas are created 3 while the raised areas 2 remain, so that the three-dimensional according to the invention structured foam board was created.
Durch rasches Heben und Senken des Stempels 8 in den beide durch den Pfeil 9 symbolisierten Richtungen ist sehr rasch eine große Quadratmeterzahl an strukturierter Schaumstoffplatte herstellbar.By quickly raising and lowering the punch 8 in both of them by the directions symbolized by the arrow 9 is very quickly a large number of square meters Can be produced on structured foam board.
Eine andere Ausführungsform der erfindungsgemäßen Vorrichtung zur Herstellung der neuen dreidimensional stru<-turierten Schaumstoffplatte bzw. Block ist in Figur 3 dargestellt; sie besteht aus einer Walze 10, deren Oberfläche 10a dreidimensional positiv strukturiert ist, wobei vorzugsweise im Innern der Walze Heizatrahler 7a angeordnet sind, deren Heizungsintensität auf an sich bekannte Art variiert wird. Diese Heizstrahler 7a verleihen der Walzenoberfläche die gewünschte Temperatur, die sich beim Verschmelzungsvorgang gewisser Schaumstoffbereiche in der oben geschilderten Art und Weise auswirkt. ac einer Ausführungsform ist nun die beheizte Walze bezuglich ihrer iidhenanordnung fixiert, wobei die zu strukturierende Schaumstoffplatte 4b im Sinn des Pfeils 11 unter der Walze 10 durchgezogen wird und diese die Relativbewegung im Sinne des Pfeils 12 ausführt; die Schaumstoffplatte 4b liegt ihrerseits auf einem Tisch 13, der beispielsweise über die Spindel 14 derart höhenverstellbar ist, daß der Anpreßdruck der zu strukturierenden Schaumstoffplatte 4b gegen die Walze 10 wünschenswerterweise variabel ist. Beim Verlassen des Walzenbereichs hat sich dann die zuvor glattflächige Schaumstoffplatte 4b in die erfindungsgemäße strukturierte Schaumstoffplate 1 transformiert.Another embodiment of the device according to the invention for Production of the new three-dimensionally structured foam board or Block is shown in Figure 3; it consists of a roller 10, the surface of which 10a is structured positively three-dimensionally, preferably in the interior of the roller Heating radiators 7a are arranged, the heating intensity of which is known per se is varied. These radiant heaters 7a give the roll surface the desired one Temperature, which during the fusion process of certain foam areas in the manner described above. ac one embodiment is now the heated roller is fixed with respect to its iidhenordnung, the one to be structured Foam sheet 4b is pulled through under the roller 10 in the direction of arrow 11 and this executes the relative movement in the direction of arrow 12; the foam board 4b, in turn, lies on a table 13 which, for example, over the spindle 14 in such a way Is adjustable in height that the contact pressure of the foam board to be structured 4b versus roller 10 is desirably variable. When leaving the roller area then has the previously smooth-surfaced foam sheet 4b into the inventive structured foam plate 1 transformed.
Nach einer anderen Ausführungsform kann auch die Walze 10 selbst beispielsweise mittels einer Transmission oder einer sonstwie auf an sich bekannte Art und Weise angeordnete motorische Kraft bewegt werden und sorgt hierbei beim kontinuierlichen Verformungsprozeß der zunächst glattflächigen Schaumstoffplatte für deren Transport.According to another embodiment, the roller 10 itself can also, for example by means of a transmission or in some other manner known per se arranged motor force can be moved and takes care of the continuous deformation process of the initially smooth-surfaced foam board for their transport.
Nach einer weiteren Aus£ührungsform kann der gewünschte Anpreßdruck zwischen den Oberflächen von Walze und Schaumstoffplatte anstelle durch eine Höhenverstellung der Schaumstoffplatte auch durch eine Höhenverstellung der Walzenaufhängung 15 im Sinne des Pfeiles 16 bewirkt werden.According to a further embodiment, the desired contact pressure between the surfaces of the roller and foam board instead of by adjusting the height the foam board also by adjusting the height of the roller suspension 15 in the The direction of arrow 16 are effected.
Die Beheizung der Metallpreßplate oder der w.1ze arm ausser durhc Heizstrahler auf jede andere A@@@@@nd Weise erfolgen, z.B. durch sch@tig elektrische Heizelemente.The heating of the metal press plate or the w.1ze arm except durhc Radiant heaters can be done in any other way, e.g. by means of sch @ tig electrical Heating elements.
Die Metallpreßplatte ul; die Walze eind bervorzugte tueführungsformen für beliebig gestaltete dreidimensional strukturierte Metallpatrizen.The metal press plate ul; the roller and preferred guide shapes for any three-dimensional structured metal male pattern.
Eine weitere Verfahrensführung besteht darin, daß man die glattflächige Schnumstcffplatte bzw. den glattflächigen Sehaumstoffblock auf die dreidimensional strukturierte, beheizbare Metallgußplatte auflegt und von oben mittels einer höhenverstellbaren, vorzugsweise herabfahrbaren planenplatte einen leichten Druck ausübt, Wie bereits oben angeführt wurde, ist sowohl die Oberfläche der in Figur 2 dargestellten strukturierten Iletallpreßplate als auch die strukturierte Oberfläche der Walze vorzugsweise mit einem Trennmittel versehen, das aus Polytetrafluoräthylen oder einem Siliconkunstharz besteht, um ein Ankleben der Hetallpreßplatte bzw. der strukturierten Walze an der Schaumstoffplatte zu verhindern. Nach einer anderen Absführungsform ist anstelle dieser Beschichtung aus Trennmittel ein aufgesprühter Trennfilm, der vorzugsweise aus Siliconöl besteht, empfehlenswert.Another procedure consists in that you the smooth-surfaced Schnumstcffplatte or the smooth-surfaced foam block on the three-dimensional structured, heatable cast metal plate is placed and from above by means of a height-adjustable, preferably a retractable tarpaulin plate exerts a slight pressure, as already was stated above, both the surface is structured as shown in FIG Iletallpreßplate as well as the structured surface of the roller preferably with a release agent made of polytetrafluoroethylene or a silicone synthetic resin exists to stick the metal press plate or the structured roller to the Foam board to prevent. Another form of deduction is instead this coating a sprayed release film made of release agent, which preferably consists of silicone oil, is recommended.
