Description

Die Erfindung betrifft einen Verbundwerkstoff für atmungsaktive Schutzanzüge, insbesondere ABC-Schutzanzüge. The invention relates to a composite material for breathable protective suits, in particular ABC protective suits.

Bereits nach dem ersten Weltkrieg war es klar, daß der Soldat eine persönliche Schutzausrüstung gegen chemische Kampfstoffe benötigt. Already after the first World War, it was clear that the soldier needs a personal protection against chemical warfare agents. Zuerst wurden Masken entwickelt, die Atemwege und Augen schützen, während der Hautschutz vernachlässigt wurde und lediglich der schwere Uniformstoff einen gewissen Schutz bot. First, masks are designed to protect the respiratory tract and eyes, while the skin protection was neglected and only the heavy uniform fabric offered some protection. Auch wurden spezielle luftdichte Planen verwendet, um sich gegen Gasangriffe, insbesondere Sprühangriffe, zu schützen. Special airtight tarpaulins were used to guard against gas attacks, especially Sprühangriffe.

Unter dem Namen "Zodiac" verwendet die Bundeswehr einen gummierten Schutzanzug mit glatter, abspritzbarer Außenschicht. Under the name "Zodiac" The Bundeswehr uses a rubberized suit with smooth, abspritzbarer outer layer. Desweiteren beschreibt die deutsche Offenlegungsschrift DE 38 29 501 A1 sowie die US-Patentschrift 48 33 010 ein mehrlagiges Material für Schutzanzüge mit glatter Oberfläche. Further, the German Offenlegungsschrift DE 38 29 501 A1 and the US patent 48 33 010 describes a multilayer material for protective clothing with a smooth surface. Diese Laminate enthalten neben einer oder mehreren Folien mit Sperrwirkung auch textile Komponenten. These laminates also contain textile components besides one or more films having a barrier effect. Wegen der fehlenden Wasserdampfdurchlässigkeit können diese Anzüge nur kurze Zeit getragen werden (Hitzestau, Körperfeuchtigkeit kann nicht entweichen). Because of the lack of water vapor permeability, these suits can be worn for a short time (accumulation of heat, body moisture can not escape).

Desweiteren sind aus den deutschen Patenten P 29 51 827 C2 und P 28 29 599 C2 sowie aus dem Gebrauchsmuster G 84 05 127 Schutzanzüge bekannt, die zwar luft- und somit wasserdampfdurchlässig sind, jedoch an der Außenseite eine rauhe, weil textile, Oberfläche haben. Furthermore, 84 05127 protective suits are known from German patent P 29 51 827 C2 and P 28 29 599 C2 as well as the utility model G known that, while air and thus permeable to water vapor, but a rough, because textile, have surface on the outside. Ein solcher Schutzanzug kann nicht abgespritzt werden und schützt nicht gegen atomaren Fall-out. Such protection suit can not be washed down does not protect against nuclear fall-out.

Es gibt zwar wasserdampfdurchlässige Folien, beispielsweise die Sympatex- Folie von Akzo/Enka-Glanzstoff, bzw. wasserdampfdurchlässige Polyurethanbeschichtungen, beispielsweise Impraperm AD-03 und LH-03 der Bayer AG, die theoretisch an der Außenseite eines Schutzanzuges aufgebracht werden könnten, jedoch nehmen diese bis zu 60% ihres Gewichts an Feuchtigkeit auf, verlieren dabei einen beträchtlichen Teil ihrer mechanischen Festigkeit und sind deshalb für eine äußere Applikation ungeeignet. While there is water vapor permeable films, such as Sympatex foil from Akzo / Enka-gloss material, or water vapor permeable polyurethane coatings, for example Impraperm AD-03 and LH-03 from Bayer AG, which could theoretically be applied to the outside of a protective suit, but take this up to 60% of its weight in moisture, thereby losing a considerable part of their mechanical strength and are therefore unsuitable for external application. Die aus dem Gebrauchsmuster G 84 05 127 bekannte mikroporöse Teflonmembran ist wegen ihrer hohen Verwundbarkeit ebenfalls als Außenmaterial ungeeignet. 84 05 127 known microporous Teflon membrane of the Utility Model G is also suitable as an exterior material due to their high vulnerability.

Gegenüber diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Verbundstoff zu schaffen, der sowohl wasserdampfdurchlässig ist als auch an der Oberfläche glatt ist, unter Einfluß von Nässe kaum quillt und mechanisch fest ist. Compared to this prior art, the invention has for its object to provide a composite material which is both permeable to water vapor than is smooth at the surface, hardly swells under the influence of moisture and is mechanically strong.

Diese Aufgabe wird gelöst mit den Merkmalen des Anspruchs 1. Hierbei wird die Festigkeit des Stoffes dadurch erreicht, daß die in Nässe auftretende Quellung der Folie durch eine dosierte Vernetzung ausreichend zurückgedrängt wird und die Folie mit dem textilen Träger vollflächig verschweißt wird. This object is achieved with the features of claim 1. Here, the strength of the fabric is achieved that the occurring in wet swelling of the film is sufficiently suppressed by a metered crosslinking and the film with the textile support is welded over the entire surface. Es wurde gefunden, daß mit Hilfe einer richtig bemessenen Quervernetzung die Quellung der genannten wasserdampfdurchlässigen Polyurethane so eingeschränkt werden kann (<30%, vorzugsweise <20%), daß auch unter Einfluß von Nässe gute mechanische Eigenschaften erhalten werden, ohne daß dabei die Wasserdampfdurchlässigkeit über Gebühr reduziert wird. It has been found that by using a properly sized crosslinking the swelling of said water vapor permeable polyurethanes can be restricted (<30%, preferably <20%) to be obtained even under the influence of moisture with good mechanical properties, without causing the water vapor permeability on fee is reduced. Wie zu vernetzen ist, ist dem Fachmann bekannt. How to link to the person skilled in the art. So ist beispielsweise aus dem Merkblatt der Bayer AG für Impranil EWN zu entnehmen, daß Desmodur-Additiv Z, ein Diisocyanat, ein geeigneter Vernetzer ist. For example, from the data sheet of Bayer AG for Impranil EWN seen that Desmodur Z-additive, a diisocyanate, a crosslinker is suitable. Die für den Effekt benötigte Menge (1 bis wenige Prozente) muß der Fachmann experimentell ermitteln. The amount needed for the effect (1 to a few percent) the expert must be determined experimentally.

Die Dicke der wasserdampfdurchlässigen Schicht, 10 - 100 µ, vorzugsweise 20 bis 70 µ beruht auf einen Kompromiß: zu dünne Folien verschleißen zu schnell, zu dicke hingegen bremsen den Feuchtedurchgang zu stark. The thickness of the moisture vapor permeable layer, 10-100 μ, preferably 20 to 70 μ is based on a compromise to thin films wear out too fast, too thick, however, slow down the moisture passage to strong.

Für die ABC-Schutzanzüge empfiehlt es sich, das textile Trägermaterial als Hitzeschutz auszubilden. For the NBC protective suits, it is recommended to form the textile backing material as a heat shield. Das kann in der Art des Patents DE 29 51 827 C2 oder DE 28 29 599 C2 geschehen, oder aber durch Verwendung moderner Fasern wie Aramide oder Benzimidazole, die dem Fachmann bekannt sind. This can be done 29 51 827 C2 or DE 28 29 599 C2 in the manner of patent DE, or by using modern fibers such as aramids or benzimidazoles, which are known in the art. Desweiteren bedarf ein ABC-Schutzanzug einer innenliegenden Adsorptionsschicht, um gegen hautgängige Kampfstoffe zu schützen. Furthermore, requires an NBC protective suit an internal adsorption layer to protect against skin continuous warfare agents. Solche Adsorptionsschichten sind ebenfalls in den beiden genannten Patenten beschrieben. Such adsorption layers are also described in the two mentioned patents.
