Description
Herstellen von Folien aus härtbaren Kunstharzen Die Erfindung erstreckt sich auf die Anwendung einer Vorrichtung, bestehend aus einer umlaufenden Walze, deren Oberfläche von innen beheizt wird und auf die an einer Stelle des Umfanges ein zu verfestigendes Kunstharz aufgebracht wird und von der die so gebildete Folie nach einer nahezu vollständigen Umdrehung der Walze abgehoben wird, zum fortlaufenden Herstellen von Folien beliebiger Längen aus keine Kondensationsnebenprodukte abspaltenden härtbaren Kunstharzen. Manufacture of Curable Resin Sheets The invention extends refer to the use of a device consisting of a rotating roller, whose surface is heated from the inside and on one point of the circumference a synthetic resin to be solidified is applied and from which the film thus formed after a nearly complete revolution of the roller is lifted off, to the continuous Manufacture of foils of any length from no condensation byproducts curable synthetic resins.
Bisher wurde bei der Herstellung solcher Folien in der Weise verfahren, daß die aus den eventuell rnit Füllstoffen versehenen Harzen gegossenen Bahnen durch Wärmetunnel geleitet wurden. Hierbei wurde die Wärmeenergie entweder durch Strahlung oder Luftumwälzung von der Wärmequelle auf das zu härtende Harz übertragen. Diese Art der Wärmeübertragung ist unwirtschaftlich, und zwar wegen der auftretenden Energieverluste und weil die Härtung zu langsam verläuft. Die Erfindung zeigt einen vorteilhaften Weg zur Vermeidung dieser Nachteile und zeichnet sich dadurch aus, daß man eine an sich bekannte Vorrichtung verwendet, die aus einer umlaufenden Walze besteht, deren Oberfläche von innen beheizt wird und auf die an einer Stelle des Umfanges ein zu verfestigendes Kunstharz aufgebracht wird und von der die so gebildete Folie nach einer nahezu vollständigen Umdrehung der Walze abgehoben wird, und zwar zum fortlaufenden Herstellen von Folien beliebiger Längen aus keine Kondensationsnebenprodukte abspaltenden härtbaren Kunstharzen, die gegebenenfalls mit Füllstoffen und Farbmitteln versehen und auf verhältnismäßig kurze Aushärtedauer eingestellt sind. So far, the production of such foils has been carried out in the manner that the webs cast from the resins, which may have been filled with fillers, come through Heat tunnels were conducted. Here the thermal energy was either through radiation or air circulation transferred from the heat source to the resin to be hardened. These The type of heat transfer is uneconomical because of the energy losses that occur and because curing is too slow. The invention shows an advantageous Way to avoid these disadvantages and is characterized by the fact that one known device used, which consists of a rotating roller, whose surface is heated from the inside and on one point of the circumference a synthetic resin to be solidified is applied and from which the film thus formed is lifted after an almost complete revolution of the roller, namely for continuous production of films of any length from no condensation by-products separating hardenable synthetic resins, optionally with fillers and colorants provided and set to a relatively short curing time.
Von der beheizten Walzenoberfläche, auf der die zu härtenden Harze aufgetragen sind, geht Wärme durch unmittelbare Berührung von der Reaktionsfläche auf das Reaktionsgut über, so daß Energieverluste vermieden sind und eine kürzere Aushärtedauer erzielt ist. From the heated roller surface on which the resins to be hardened are placed are applied, heat is released through direct contact with the reaction surface on the reaction mixture over, so that energy losses are avoided and a shorter one Curing time is achieved.
Es ist auch möglich, die Kunststoffolie durch Verbindung mit einem Gewebestreifen zu armieren, indem man diesen Gewebestreifen, z. B. ein Gewebe aus Baumwolle, Seide, Glas oder einem anderen webfähigen Stoff, z. B. Drahtgewebe, auf die noch nicht ausgehärtete Fläche des Bandes aufpreßt. Man kann dabei das Gewebe noch mit einer weiteren Schicht Kunststoff bedecken. Auch eine andere Masse kann aufgetragen werden, z. B. Schaumstoff, als Isolier-oder Polsterschicht. It is also possible to attach the plastic film to a To reinforce fabric strips by this fabric strip, z. B. a fabric Cotton, silk, glass or another woven fabric, e.g. B. wire mesh the not yet hardened surface of the tape presses on. You can do the tissue cover with another layer of plastic. Another mass can be applied, e.g. B. foam, as an insulating or cushioning layer.
Um die Bedingungen für die Herstellung der Folien nach Bedarf verändern zu können, benutzt man eine Walze von großem Durchmesser, die innen beheizt oder gekühlt werden kann und außerhalb ihres Um- fanges von den verschiedenen für den Arbeitsgang notwendigen Einrichtungen so umgeben ist, daß diese Einrichtungen in ihrer Winkelstellung um die Drehachse der Trommel verstellt werden können. To change the conditions for the production of the foils as needed To be able to use a roller of large diameter that is heated or internally can be cooled and outside of their environment catch of the different for the Work necessary facilities is surrounded so that these facilities in their angular position can be adjusted about the axis of rotation of the drum.
Durch Einstellen der Trommeldrehzahl, der Tro.nmelbeheizung bzw. Kühlung und der Abstandswinkel zwischen den verschiedenen Außenvorrichtungen ist man in der Lage, die je nach der Art des Stoffes und nach den gewünschten Eigenschaften bestehenden Arbeitsbedingungen zu erfüllen. By setting the drum speed, the drum heating or Cooling and the angle of distance between the various external devices one will be able to do that depending on the type of substance and on the properties desired to meet existing working conditions.
Man kann die so hergestellten endlosen Kunststoffbänder noch im selben Arbeitsgang auf biegsame Platten aufbringen, deren Oberfläche durch den Kunststoff verbessert werden soll. Zu diesem Zweck wird die biegsame Platte von außen an die umlaufende Herstellungswalze herangeführt, so daß sie den Umfang der mit Kunststoff bedeckten Walze in einem vorgeschriebenen Winkelbereich berührt. The endless plastic belts produced in this way can still be used in the same Apply the operation to flexible plates, the surface of which is covered by the plastic should be improved. For this purpose, the flexible plate is attached to the outside of the revolving production roller brought up so that they the circumference of the plastic covered roller in a prescribed angular range.
Man kann aber auch den hinreichend ausgehärteten Kunststoff durch eine Abhebewalze von der Herstellungswalze abheben und ihn dann entweder aufrollen oder ihn auf eine Bahn leiten, auf der er in ununterbrochener Folge mit ebenen Platten aus anderem Werkstoff vereinigt wird. But you can also use the sufficiently hardened plastic lift a lift-off roller from the make roller and then either roll it up or guide him on a track, on which he in uninterrupted sequence with flat plates is combined from another material.
