Description
Verfahren zur Nachverformung von Folien oder Tafeln aus biegsamem Polyurethanschaumstoff Die Erfindung bezieht sich auf ein Verfahren zur Nach- bzw. Ausformung von Folien oder Tafeln aus biegsamem Polyurethanschaumstoff in eine Dauerform mit dünnen Querschnittsteilen, wie sie für Deckpolster von Autositzen oder -rücklehnen verwendet werden.Process for the post-deformation of foils or sheets made of flexible Polyurethane foam The invention relates to a method for adjusting or Forming of foils or panels made of flexible polyurethane foam into a permanent form with thin cross-sectional parts, such as those used for the cover padding of car seats or backrests be used.
Polyurethanschaumstoffe sind infolge ihrer hohen Elastizität besonders zur Herstellung von Polstermaterialien geeignet. Es ist bekannt, aus Polyurethanschaumstoff dicke Tafeln herzustellen, die für Deckpolster für Sitzkissen von Kraftwagen durch Spalten oder Schneiden in dünne Tafeln von gleichmäßiger Stärke umgewandelt werden. Es ist auch bekannt, daß eine Tafel oder Platte aus Polyurethanschaumstoff unter gleichzeitiger Wärme- und Druckeinwirkung derart verformt werden kann, daß sie an den Preßstellen linsenförmigen Querschnitt annimmt und an den zusammengedrückten Stellen verschweißt wird. Hierbei handelt es sich um die gleichmäßige Ausformung der Tafeln auf beiden Seiten. Polyurethane foams are special because of their high elasticity suitable for the production of upholstery materials. It is known from polyurethane foam Manufacture of thick panels that are used for cover cushions for seat cushions in motor vehicles Split or cut into thin sheets of uniform thickness. It is also known to have a sheet or plate made of polyurethane foam under simultaneous heat and pressure can be deformed in such a way that they at the pressing points assumes a lenticular cross-section and at the compressed Places is welded. This is the uniform shape of the panels on both sides.
Wegen der starken inneren Elastizität von Polyurethanschaumplatten glaubte man, daß die Ausformung nur einer Fläche dieser gleichmäßig dicken Platten in einer erhitzten Preßform auch zur Verformung der anderen Plattenseite führen würde, wenn letztere nicht an einer starren ebenen Fläche anlag. Aus diesem Grunde wurde es für unmöglich gehalten, auf diese Weise Deckpolster mit Anteilen von unterschiedlicher Stärke und Form herzustellen, wie sie z. B. für Sofalehnen oder Kraftwagensitze erwünscht sind. Because of the strong internal elasticity of polyurethane foam sheets it was believed that the formation of only one face of these uniformly thick plates in a heated mold also lead to the deformation of the other side of the plate would if the latter did not rest on a rigid flat surface. For this reason It was considered impossible in this way to produce deck pads with proportions of different Manufacture strength and shape, such as. B. for sofa arms or car seats are desired.
Nach dem Verfahren der Erfindung werden Folien oder Tafeln aus biegsamem Polyurethanschauinstoff gleichmäßiger Dicke durch einseitiges Eindrücken von bleibenden Vertiefungen in den zwischen einer ebenen Platte und einem die Vertiefungen bewirkenden Formglied befindlichen Schaumstoff unter Erhitzen der zusammengedrückten bzw. verdichteten Teile auf mindestens 1200 C dadurch versehen, daß der Schaumstoff an der von den Eindrückungen freien Fläche durch die auf die Verformungstemperatur erhitzte ebene Platte erwärmt wird. According to the method of the invention, sheets or sheets are made of flexible Polyurethane foam of uniform thickness by pressing on one side with permanent Wells in the between a flat plate and one causing the wells Molded member located foam under heating the compressed or compressed Parts provided to at least 1200 C by the fact that the foam at the of the Indentations free surface due to the plane heated to the deformation temperature Plate is heated.
Diese Hitzeeinwirkung ist unerwarteter Weise die Ursache, daß die ebene (Boden-) Fläche der Folie oder Tafel unverändert ihre glatte Form beibehält. This exposure to heat is unexpectedly the cause that the flat (floor) surface of the film or board retains its smooth shape unchanged.
Das erfindungsgemäße Verfahren sei an Hand der Zeichnungen erläutert. The method according to the invention will be explained with reference to the drawings.
Fig. 1 ist ein Teilquerschnitt im Aufriß und stellt eine Preßform mit Stahlschienen dar, in der sich ein Polyurethanschaumstoff befindet, der erfindungsgemäß geformt werden soll; Fig. 2 ist ein Teilquerschnitt im Aufriß, der die erste Phase des Formvorganges darstellt, indem der Stahlschienenstempel die Schaummasse an den gewünschten Stellen zusammendrückt; Fig. 3 ist eine perspektivische Teilansicht eines ausgeformten Gegenstandes aus Polyurethanschaumstoff; Fig. 4 ist ein vergrößerter Teilquerschnitt im Aufriß entlang der in Fig. 3 angegebenen Linie 4-4; Fig. 5 ist eine Teilseitenansicht im Aufriß und zeigt im Querschnitt einen Schichtstoffkörper aus Polyurethanschaumstoff mit einer dünnen Polyvinylchlorid-Deckschicht, von dem ein Teil entfernt ist; Fig. 6 ist ein vergrößerter Querschnitt im Aufriß entlang den in Fig. 5 angegebenen Linien; Fig. 7 ist ein seitlicher Aufriß eines Stahlschienenstempels mit einer dielektrischen Heizvorrichtung. Fig. 1 is a partial cross-section in elevation showing a die with steel rails in which there is a polyurethane foam according to the invention to be shaped; Fig. 2 is a partial cross-section in elevation showing the first phase of the molding process represents by the steel rail stamp the foam mass to the compress the desired places; Fig. 3 is a partial perspective view a molded article made of polyurethane foam; Fig. 4 is an enlarged one Partial cross-section in elevation along line 4-4 indicated in Figure 3; Fig. 5 is Fig. 3 is a partial side elevational view showing a laminate body in cross section made of polyurethane foam with a thin polyvinyl chloride top layer, of which part is removed; Fig. 6 is an enlarged cross section taken along in elevation the lines indicated in Figure 5; Figure 7 is a side elevation of a steel rail stamp with a dielectric heater.
Die verhältnismäßig dicke Tafel 1 aus einem zelligen Polyurethanelastomeren befindet sich in einer Preßform mit Stahlschienen. Die Preßform besitzt eine Bodenplatte 5 und eine bewegliche Platte 6 mit zahlreichen Formgliedern 7, die mit dem Stempel in Verbindung stehen, die alle eine verhältnismäßig kleine Vorderfläche8 zur Berührung mit dem zelligen Polyurethankunststoff haben. Zwecks Verkürzung der Dauer der Ausformung auf eine günstige Zeit von etwa 2 bis 6 Minuten werden Teile des Polyurethanschaumstoffes, deren Dicke verringert werden soll, auf eine Temperaur von mindestens etwa 1200 C, vorzugsweise von etwa 150 bis 24aO C, erwärmt. Die Erwärmung kann beispielsweise durch Dampf erfolgen, der durch ein Zuführungsrohr 13 in den Dampfraum 12 unterhalb der Bodenplatte eintritt. Die mit dem Stempel verbundenen Glieder können ebenfalls mittels Dampf erwärmt werden, der in den Dampfraum 15 der Platte 6 durch ein Einlaßrohr 16 eintritt. The relatively thick panel 1 made of a cellular polyurethane elastomer is in a press mold with steel rails. The mold has a bottom plate 5 and a movable plate 6 with numerous mold members 7, which with the punch are connected, all of which have a relatively small front surface8 for contact with the cellular polyurethane plastic. For the sake of shortening the Parts are molded in a convenient time of about 2 to 6 minutes of the polyurethane foam, the thickness of which is to be reduced, to a temperature of at least about 1200 ° C, preferably from about 150 to 24aO C, heated. The warming can be done, for example, by steam flowing through a feed pipe 13 into the Steam space 12 enters below the bottom plate. Those associated with the stamp Links can also be heated by means of steam flowing into the steam space 15 of the Plate 6 enters through an inlet tube 16.
Die Wärmeeinwirkung soll so lange erfolgen, bis der Schaumstoff seine Neigung verliert, nach dem Abkühlen wieder in seinen ursprünglichen Zustand zurückzukehren. Der verformte Körper kann aus der Form entfernt werden, ohne daß abgekühlt oder überschüssiges Material an den Seitenkanten abgeschnitten wird. The heat should continue until the foam has its Loses its tendency to return to its original state after cooling. The deformed body can be removed from the mold without cooling or excess material is cut off at the side edges.
Die Oberflächen23, 24 des verformten Schaumstoffes stellen verhältnismäßig große, flach gewölbte Flächen dar, deren Einschnitte 25 sich allmählich von oben nach unten verengen. Die untere Seite bzw. der Boden 26 des Formkörpers ist infolge der Wärmeeinwirkung unverändert eben als bleibende Kontur. Der Schaumstoff und der Preßstempel oder die Formglieder können auch auf andere Weise erwärmt werden, z. B. durch dielektrische Erwärmung, wie es in Fig. 7 gezeigt ist. Hierbei bilden die Formglieder mit den schmalen Flächen 7a, die mit der oberen Platte 6a verbunden sind, die eine Elektrode, während die untere Platte 5a die Gegenelektrode ist. The surfaces 23, 24 of the deformed foam represent relatively large, flat curved surfaces, the incisions 25 gradually from above narrow down. The lower side or the bottom 26 of the shaped body is due to the effect of heat unchanged as a permanent contour. The foam and the The ram or the mold members can also be heated in other ways, e.g. By dielectric heating as shown in FIG. Here are the Form members with the narrow surfaces 7a, which are connected to the top plate 6a are the one electrode, while the lower plate 5a is the counter electrode.
Ein geeigneter Hochfrequenzgenerator36 wird mit den Elektroden verbunden und erzeugt ein hochfrequentes elektrostatisches Feld, das auf die Punkte konzentriert ist, an denen die Tafel zwischen den Formgliedern am stärksten zusammengepreßt wird.A suitable high frequency generator 36 is connected to the electrodes and creates a high frequency electrostatic field that focuses on the points is where the panel is most compressed between the mold members.
Ist die Bodenplatte verhältnismäßig kühl, wenn sie mit dem Schaum stoff und dem Stempel oder den Formgliedern in Berührung steht, so quillt, wie gefunden wurde und wie in Fig. 5 angegeben ist, der Schaumstoff auf beiden Seiten heraus. Dieses Verfahren ist für die Herstellung von z. B. Kissen geeignet. The bottom plate is relatively cool when it is covered with the foam substance and the stamp or the molded elements is in contact, so swells, as found and as indicated in Fig. 5, the foam out on both sides. This method is suitable for the production of e.g. B. Suitable for pillows.
Die Formteile7 sind im allgemeinen Streifen aus gut leitendem Material, z.B. aus Aluminium oder Kupfer. Ihre Länge erstreckt sich vorzugsweise über die Schaumstofftafel, und ihre Höhe ist groß genug, um eine Berührung der oberen Platte mit der Oberfläche der Tafel zu vermeiden. Die Breite der berührenden Teile der Formglieder 7 ist gering, vorzugsweise etwa 1,55 bis 12,5 mm, so daß Wärme und Druck im Inneren auf eine kleine Fläche des Kissens begrenzt bleiben. The molded parts7 are generally strips of highly conductive material, e.g. made of aluminum or copper. Their length extends preferably over the foam board, and their height is large enough to allow the top plate to contact the surface to avoid the blackboard. The width of the contacting parts of the molded members 7 is small, preferably about 1.55 to 12.5 mm, so that heat and pressure inside to a little The area of the pillow remains limited.
Erfindungsgemäß kann auch eine verhältnismäßig dünne, biegsame Schicht 30 (Fig. 6) aus einem Kunststoff, z.B. aus Polyvinylchlorid, über den Schaumstoff gelegt und über der Oberseite23 des Materials so geformt werden, daß sie im wesentlichen den Umrissen der Oberseite23 folgt. Die thermoplastische Polyvinylchloridschicht und der Polyurethanschaumstoff werden während des Erwärmens durchVerschmelzen teilweise miteinander verbunden, und jede Schicht neigt dazu, die Kriecheigenschaften der anderen zu verändern, wodurch sie die Haltbarkeit der gewünschten Kontur begünstigt. Das Verschweißen der Polyvinylchloridschicht mit der Polyurethanschaumstoffschicht kann durch ein geeignetes Bindemittel, z.B. ein Epoxydharz und ein Vinylchloridpolymerisat enthaltendes Bindemittel, erleichtert werden. According to the invention, a relatively thin, flexible layer can also be used 30 (Fig. 6) made of a plastic such as polyvinyl chloride over the foam and shaped over the top 23 of the material so that they are essentially follows the outlines of the upper side23. The thermoplastic polyvinyl chloride layer and the polyurethane foam are partially melted while being heated interconnected, and each layer tends to reduce the creep properties of the to change others, thereby favoring the durability of the desired contour. The welding of the polyvinyl chloride layer to the polyurethane foam layer can by a suitable binder, e.g. an epoxy resin and a vinyl chloride polymer containing binder.
Der Decküberzug aus Polyvinylchlorid liefert ein Polstermaterial, das leicht zu reinigen ist, feuer- und feuchtigkeitsbeständig ist und mittels leuchtenden Farben gefärbt werden kann. The top coat made of polyvinyl chloride provides a cushioning material, that is easy to clean, fire and moisture resistant and has luminous Colors can be colored.
