Description

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

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

Unter dem Namen "Zodiac" verwendet die Bundeswehr einen gummierten Schutzanzug mit glatter, abspritzbarer Außenschicht. 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. Diese Laminate enthalten neben einer oder mehreren Folien mit Sperrwirkung auch textile Komponenten. Wegen der fehlenden Wasserdampfdurchlässigkeit können diese Anzüge nur kurze Zeit getragen werden (Hitzestau, Körperfeuchtigkeit kann nicht entweichen).The Bundeswehr uses a rubberized protective suit under the name "Zodiac" with smooth, sprayable outer layer. Furthermore describes the German patent application DE 38 29 501 A1 and the US patent 48 33 010 a multi-layer material for protective suits with a smooth surface. These laminates contain one or more foils with a barrier effect also textile components. Because of the lack of water vapor permeability these suits can only be worn for a short time (heat build-up, body moisture cannot 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. Ein solcher Schutzanzug kann nicht abgespritzt werden und schützt nicht gegen atomaren Fall-out. Furthermore, from the German patents P 29 51 827 C2 and P 28 29 599 C2 as well as from utility model G 84 05 127 protective suits known are permeable to air and therefore water vapor, but one on the outside rough, because textile, have surface. Such a protective suit cannot be hosed down and does not protect against atomic 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. Die aus dem Gebrauchsmuster G 84 05 127 bekannte mikroporöse Teflonmembran ist wegen ihrer hohen Verwundbarkeit ebenfalls als Außenmaterial ungeeignet.There are water vapor permeable foils, for example the Sympatex Akzo / Enka-Glanzstoff film or water vapor permeable polyurethane coatings, for example Impraperm AD-03 and LH-03 from Bayer AG, the could theoretically be applied to the outside of a protective suit, however, these absorb up to 60% of their weight in moisture, lose it and a considerable part of their mechanical strength therefore unsuitable for external application. The from the utility model G 84 05 127 known microporous Teflon membrane is because of its high vulnerability also unsuitable as outer material.

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 is based on the object to create a composite that is both water vapor permeable as is also smooth on 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. 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. Wie zu vernetzen ist, ist dem Fachmann bekannt. So ist beispielsweise aus dem Merkblatt der Bayer AG für Impranil EWN zu entnehmen, daß Desmodur-Additiv Z, ein Diisocyanat, ein geeigneter Vernetzer ist. Die für den Effekt benötigte Menge (1 bis wenige Prozente) muß der Fachmann experimentell ermitteln.This object is achieved with the features of claim 1 the strength of the fabric is achieved in that the occurring in the wet The swelling of the film is adequately suppressed by metered crosslinking and the film is fully welded to the textile backing. It it was found that with the help of a properly dimensioned cross-linking the Swelling of the water vapor-permeable polyurethanes mentioned is restricted can be (<30%, preferably <20%) that under influence good mechanical properties are obtained from wetness without the Water vapor permeability is reduced excessively. How to network is known to the person skilled in the art. For example, from Bayer AG's leaflet for Impranil EWN that Desmodur additive Z, a diisocyanate, is a suitable crosslinker. The amount required for the effect (1 to a few percent) the expert must determine 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 water vapor permeable layer, 10-100 μ, preferably 20 up to 70 µ is based on a compromise: films that are too thin wear out fast, too thick, on the other hand, slow down the passage of moisture too much.  

Für die ABC-Schutzanzüge empfiehlt es sich, das textile Trägermaterial als Hitzeschutz auszubilden. 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. Desweiteren bedarf ein ABC-Schutzanzug einer innenliegenden Adsorptionsschicht, um gegen hautgängige Kampfstoffe zu schützen. Solche Adsorptionsschichten sind ebenfalls in den beiden genannten Patenten beschrieben.For the ABC protective suits, it is recommended to use the textile backing material as Train heat protection. This can be done in the manner of the patent DE 29 51 827 C2 or DE 28 29 599 C2, or by using modern fibers such as aramids or benzimidazoles, which are known to the person skilled in the art. Furthermore, an ABC protective suit requires an internal adsorption layer, to protect against skin-penetrating warfare agents. Such adsorption layers are also described in the two patents mentioned.
