Aufgabe der vorliegenden Erfindung war es daher, ein in seinen Trageeigenschaften verbesserten Material zur Verfügung zu stellen, welches bei guter Chemikalienbeständigkeit und Gasdichtheit auf einfache Weise herstellbar ist und einen breiten Anwendungsbereich besitzt.Object of the present invention it was therefore a material with improved wearing properties to disposal to provide, which with good chemical resistance and gas tightness on simple Can be manufactured and has a wide range of applications.
Die Aufgabe wird durch ein gasdichtes, chemikaliendichtes Laminat mit den Merkmalen des Anspruches 1 erfüllt. Dieses erfindungsgemäße Laminat besteht aus einem textilen Flächengebilde auf welches eine gegen Säuren und Alkalien sowie die meisten organischen Lösungsmittel beständige, gasdichte weichelastische Folie aufgetragen ist. Das textile Flächengebilde kann ein Gewirk, ein Gewebe, ein Vlies ein oder Multiaxialgelege sein, welches aus Synthesefasern oder nativen Fasern gebildet ist. Vorzugsweise wird das textile Flächengebilde aus einem Polyester hergestellt, das eine minimale Feuchte enthält.The task is performed by a gas-tight, Chemical-tight laminate with the features of claim 1 fulfilled. This laminate according to the invention consists of a textile fabric one against acids and alkalis as well as most organic solvents resistant, gastight soft elastic film is applied. The textile fabric can be a knitted fabric, a woven fabric, a fleece or a multi-axial scrim be, which is formed from synthetic fibers or native fibers. The textile fabric is preferred Made from a polyester that contains minimal moisture.
Auf dieses textile Flächengebilde wird einseitig oder beidseitig eine gasdichte, weichelastische Folie als Barrierefolie aufgetragen. Hierbei handelt es sich vorzugsweise um eine Coextrusionsfolie, die aus einer Schicht Polyurethan-Ether und einer Schicht Polyurethan-Ester besteht. Im Laminat bildet die Polyurethan-Ether-Schicht die äußere Schicht, d.h. die Schicht, die zuerst mit den aggressiven Medien in Kontakt kommt. Diese Polyurethan-Ether-Schicht ist insbesondere hydrolysestabil, d.h. sehr beständig gegen Säuren und Alkalien. Organische Flüssigkeiten, wie beispielsweise Triethylamin, können diese Polyurethan-Ether-Schicht jedoch durchdringen, werden dann von der darunterliegenden Polyurethan-Ester-Schicht, die eine hohe Beständigkeit gegen organische Lösungsmittel besitzt, aufgehalten.On this textile fabric becomes a gas-tight, soft-elastic film on one or both sides applied as a barrier film. This is preferably a coextrusion film made from a layer of polyurethane ether and a layer of polyurethane ester. In the laminate forms the Polyurethane ether layer the outer layer, i.e. the layer that comes into contact with the aggressive media first. This polyurethane ether layer is particularly stable to hydrolysis, i.e. very stable against acids and alkalis. Organic liquids, such as triethylamine, but can penetrate this polyurethane ether layer, are then covered by the underlying polyurethane ester layer high durability against organic solvents owns, stopped.
Die Coextrusionsfolie wird nach an sich bekannten Verfahren mit dem Polyester-Flächengebilde mittels Kalandrierbehandlung verbunden, wobei die Coextrusionsfolie stets so auf das Polyester-Flächengebilde aufgebracht wird, dass die Polyurethan-Ether-Schicht die äußere Schicht des entstehenden Laminats bildet und die Polyurethan-Ester-Schicht mit dem Polyester-Flächengebilde verbunden wird. Bei dieser Kalandrierbehandlung wird die Polyurethan-Ester-Schicht vorzugsweise in das textile Flächengebilde eingedrückt. Die äußere Polyurethan-Ether-Schicht bleibt dabei aufgrund des höheren Schmelzpunktes unverändert.The coextrusion film is after known methods with the polyester fabric connected by calendering treatment, the coextrusion film always so on the polyester fabric is applied that the polyurethane ether layer the outer layer of the resulting laminate and the polyurethane ester layer with the polyester fabric is connected. In this calendering treatment, the polyurethane ester layer preferably in the textile fabric pressed. The outer polyurethane ether layer remains doing because of the higher Melting point unchanged.
Des Weiteren kann das Laminat auch mittels eines Schmelzwalz-Kalanders, durch eine Direktextrusion der Folie auf das textile Flächengebilde hergestellt werden.The laminate can also by means of a melt rolling calender, by direct extrusion the film on the textile fabric getting produced.
Zur Fertigung des Laminates sind auch Streich- oder Beschichtungsverfahren denkbar, bei denen zuerst die Polyurethan-Ester-Schicht und anschließend die Polyurethan-Ether-Schicht auf das Trägertextil aufgebracht werden oder umgekehrt.To manufacture the laminate are coating or coating processes are also conceivable, in which case first the polyurethane ester layer and then the polyurethane ether layer on the backing textile be applied or vice versa.
In einer besonders bevorzugten Ausführungsform wird das Laminat durch ein Laminierverfahren hergestellt, wo die Coextrusionsfolien zusammen oder einzeln mit dem textilen Flächengebilde in eine Laminiervorrichtung einlaufen und sich um eine beheizte Trommel, die sich dreht, bewegen. Durch einen Flächendruck, der zwischen der Trommel und einem als Transportband mitlaufenden Silikonband aufgebaut wird, und die von der beheizten Trommel ausgehende Wärme beginnt die leichter schmelzbare Polyurethan-Ester-Schicht zu schmelzen und lässt sich in das textile Flächengebilde drücken.In a particularly preferred embodiment the laminate is made by a lamination process where the Coextrusion films together or individually with the textile fabric run into a laminator and a heated one Move the drum that is rotating. A surface pressure between the Drum and a silicone belt running as a conveyor belt and the heat from the heated drum begins to melt the more easily meltable polyurethane ester layer and can be into the textile fabric to press.
Das auf diese Weise gebildete Laminat weist eine gute Beständigkeit gegen eine Reihe von Chemikalien auf. Die Medienbeständigkeit gegenüber den Chemikalien kann durch den polymeren Aufbau der Coextrusionsfolie verstärkt werden. So ist der Grad der Permeation abhängig vom Kristallisationsgrad, vom durchschnittlichen Polymerisationsgrad und vom strukturellen Aufbau des Polymers. Ein kristallines Polyurethan-Ether-Polymer besitzt damit eine höhere Beständigkeit gegen Säuren, als ein weniger kristallines Polyurethan-Ether-Polymer, d.h. durch den Kristallisationsgrad lässt sich beeinflussen, welche Zeit beispielsweise Schwefelsäure benötigt, um die Polyurethan-Ether-Schicht zu durchdringen. Der Kristallisationsgrad kann jedoch nicht beliebig hoch gewählt werden, da mit dem Erhöhen des Kristallisationsgrades die Dehnung und Elastizität der Schicht verringert wird. Für eine Verwendung des Laminats, beispielsweise für Schutzanzüge, ist jedoch eine ausreichende Elastizität Voraussetzung.The laminate formed in this way has good resistance to a number of Che micro on. The media resistance to the chemicals can be increased by the polymer structure of the coextrusion film. The degree of permeation depends on the degree of crystallization, the average degree of polymerization and the structural structure of the polymer. A crystalline polyurethane ether polymer thus has a higher resistance to acids than a less crystalline polyurethane ether polymer, ie the degree of crystallization can influence what time, for example, sulfuric acid takes to penetrate the polyurethane ether layer. However, the degree of crystallization cannot be chosen to be arbitrarily high, since the increase in the degree of crystallization reduces the elongation and elasticity of the layer. However, sufficient elasticity is a prerequisite for using the laminate, for example for protective suits.
Das erfindungsgemäße Laminat kann im medizinischen Bereich eingesetzt werden, da es physiologisch unbedenklich ist. Wird es als Abdeckmaterial eingesetzt reicht es aus, ein textiles Flächengebilde mit einer einseitig aufgebrachten Coextrusionsfolie zu benutzen. Zur Herstellung von Schutzanzügen mit Barrierewirkung ist jedoch eine beidseitige Beschichtung des textilen Flächengebildes mit einer Coextrusionsfolie notwendig. Bei solchen Schutzanzügen kann es sich beispielsweise auch um Taucheranzüge handeln. Für die Anwendung als Schutzbekleidung ist es vorteilhaft, dass das Laminat schweißbar ist, beispielsweise durch Hochfrequenzschweißen, durch Impulswärmeschweißen oder Heißluftschweißen.The laminate according to the invention can be used in medical Be used because it is physiologically harmless. If it is used as a covering material, a textile is sufficient sheet to be used with a coextrusion film applied on one side. For the production of protective suits with However, the barrier effect is a double-sided coating of the textile sheet necessary with a coextrusion film. With such protective suits for example, it is also a diving suit. For the application as protective clothing it is advantageous that the laminate is weldable, for example by high-frequency welding, by pulse heat welding or Hot air welding.
