Description

       

  



  Verfahren zur Herstellung von Gebilden, wie   Sehiehtèn,    Folien, Platten und Filmen aus Kunstharz.



   Bei der   Bsserstellung    von Schichten, Folien, Platten und F'ilmen aus   thermoplasti-    schen   Eunstharz-Weichmachermassen    werden entsprechende Mischungen entweder durch Druck und erhöhte Temperatur oder durch Temperaturerhöhung allein gelatiniert, wobei die verschiedensten bekannten Kunstharze und Weichmacher, wie z. B. P'olyvinylchlorid, Vinylchlorid/Vinylacetat,   Vinylchlorid/Vi-    nylidenchlorid,   Vinylchlorid/Acrylsaureester,      VinylchloridlMethacrylsäureesber, Vinylchlo-      rid/Vinylcarbazol    usw., in den verschiedensten Mischungsverhältnissen verwendet werden.



   Bei der Einstellung und Konstanthaltung der notwendigen optimalen   Gelatinier-Tem-    peratur haben sich Schwierigkeiten besonders in der raschen Regulierung der   Wärmezu-oder-abfuhrgezeigt. Dadie    physikalischen und chemischen Eigenschaften derartiger Gebilde weitgehend von einer gleichmässigen Gelatinier-Temperatur abhängen, war es wiinschenswert, eine besser regulierbare und rascher wirkende Wärmequelle zu finden.



   Gegenstand vorliegender Erfindung ist nun ein Verfahren, das als Wärmequelle allein oder als leicht steuerbare Ergänzang der gebräuchlichen Heizungsmethoden für solche Zwecke infrarote Strahlen verwendet.



   Die   infrarote    Bestrahlung kann an verschiedenen Stellen als FabrikationsprozeB eingeschaltet werden, z.   B.    bei den Walzwerken, bei den Kalandern, bei den Streichmaschinen, bei den   Gelatinieranlagen,    bei den Spritzmaschinen usw.



   Während in der bisher üblichen industriellen Verwendung von infraroten Strahlen zur Trocknung von Lackschichten durch die Temperaturerhöhung lediglich ein Verdampfen der Losungsmittel bewirkt wird, ist im vorliegenden Falle eine Beschleunigung der Uberführung vom grobdispersen Zustand in den kolloidalen Gelzustand erzielt worden.



  Besonders bewährt hat sich das. hier vorge  schlagene    Verfahren zur   Gelatinierung    von dünnen Filmen aus Pblyvinylverbindungen mit Weichmachern auf Trägern wie Papier, Kleidungsstücken usw. Ausser der leichten  Temperaturregulierung und genauen Dosierung in der Wärmezufuhr besteht ein weiterer Vorteil darin, daB es möglich ist, nur die zu gelatinierende Schicht zu erwärmen, ohne dass   temperaturempfindliches    Trägermaterial (Textilien, Papier usw.) auch bei   Gelatiniertemperaturen    von 200  und darüber gefährdet ist.



   Beispiel :
Ein Zellwollgewebe wird auf einer   Streichmaschine    mit einem Film von zirka 100 g pro m2 einer Polyvinylchlorid-Butylphtalat-Paste   1    :   1    belegt. Der   Eunstharzfilm    auf dem bestrichenen Sboff ist weich,   prak-    tisch ohne Festigkeit und wasserdurchlässig.



  Wird nun diese Polyvinylchlorid-Butylphtalat-Schicht während zirka 40 Sek. der Infra  rotbestrahlung    ausgesetzt, so wird ein   mecha-    nisch sehr hochwertiger, elastischer, flexibler   Kunstharzfilm    erzeugt. Der nun   wasserun-    durchlässige Stoff eignet sich   ausgezeich-    net zur Herstellung von Regenbekleidung aller Art.



  



  Process for the production of structures such as glasses, foils, plates and films made of synthetic resin.



   In the production of layers, foils, plates and films from thermoplastic synthetic resin plasticizer compositions, corresponding mixtures are gelatinized either by pressure and increased temperature or by increasing the temperature alone, using a wide variety of known synthetic resins and plasticizers, such as e.g. B. polyvinyl chloride, vinyl chloride / vinyl acetate, vinyl chloride / vinylidene chloride, vinyl chloride / acrylic acid ester, vinyl chloride / methacrylic acid, vinyl chloride / vinyl carbazole etc., can be used in a wide variety of mixing ratios.



   When setting the necessary optimal gelatinizing temperature and keeping it constant, difficulties have arisen particularly in the rapid regulation of the heat supply or removal. Since the physical and chemical properties of such structures largely depend on a uniform gelatinization temperature, it was desirable to find a more controllable and faster acting heat source.



   The present invention now relates to a method which uses infrared rays as a heat source alone or as an easily controllable supplement to the conventional heating methods for such purposes.



   The infrared radiation can be switched on at various points as a fabrication process, e.g. B. in the rolling mills, in the calenders, in the coating machines, in the gelatinizing plants, in the injection molding machines, etc.



   While in the previously customary industrial use of infrared rays to dry paint layers, the temperature increase only causes the solvent to evaporate, in the present case an acceleration of the conversion from the coarsely dispersed state to the colloidal gel state has been achieved.



  The method proposed here for the gelatinization of thin films of polyvinyl compounds with plasticizers on substrates such as paper, clothing, etc. In addition to the easy temperature regulation and precise metering of the heat supply, another advantage is that it is possible to use only the to heat the layer to be gelatinized without endangering temperature-sensitive carrier material (textiles, paper, etc.) even at gelatinizing temperatures of 200 and above.



   Example:
A cellular wool fabric is coated on a coating machine with a film of around 100 g per m2 of a polyvinyl chloride butyl phthalate paste 1: 1. The synthetic resin film on the coated Sboff is soft, practically without strength and permeable to water.



  If this polyvinyl chloride-butyl phthalate layer is exposed to infrared radiation for about 40 seconds, a mechanically very high-quality, elastic, flexible synthetic resin film is produced. The now water-impermeable material is ideal for the manufacture of rainwear of all kinds.
