Abstract

Device for camouflaging objects and persons, comprises a knitted or woven material, which is provided with a coating that exhibits or comprises a conductive polymer (intrinsically conductive polymer (ICP)). An independent claim is included for producing a camouflaging device comprising coating a fabric or interlaced yarn based on a synthetic polymer with a formulation based on ICP, like polyaniline, polypyrrole or polythiophene, by spraying with the help of a squeegee in an immersion bath.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Tarnen von Objekten und/oder Personen gemäss dem Oberbegriff nach Anspruch 1 sowie ein Verfahren zu deren Herstellung.The present invention relates to a device for camouflaging objects and / or persons according to the preamble of claim 1 and to a method for the production thereof.

Die Tarnung von Objekten wird durch den Einsatz von neueren Technologien, wie Radar, Infrarotnachtsichtgeräten und dgl. immer schwieriger, so dass herkömmliche Tarnnetze, Tarnanzüge und dgl. kaum noch Schutz vor dem Erkennen bieten. Es sind wohl Massnahmen bekannt, insbesondere um Radarerkennung zu verhindern, wie beispielsweise Beschichtung von Tarnnetzen oder von zu tarnenden Objekten auf Basis von metallenen Füllstoffen, wie beispielsweise auf Basis von Metallpulvern oder Metallfasern bzw. auf Basis von Ferrit, wie beispielsweise Karbonyleisenferrit.Camouflaging objects becomes more and more difficult through the use of newer technologies such as radar, infrared night vision devices and the like, so that conventional camouflage nets, camouflage suits and the like barely provide protection against detection. Measures are well known, in particular to prevent radar detection, such as coating camouflage nets or camouflaged objects based on metal fillers, such as based on metal powders or metal fibers or on the basis of ferrite, such as carbonyl iron ferrite.

Insbesondere Beschichtungen auf Basis von Ferrit haben den Nachteil, dass sie relativ schwer sind und der Beschichtungsvorgang nicht unproblematisch ist. Auch eine individuelle Farbgebung ist infolge des Füllstoffes auf Basis von Eisen nicht immer möglich.In particular, coatings based on ferrite have the disadvantage that they are relatively heavy and the coating process is not without problems. An individual coloring is not always possible due to the filler based on iron.

In der EP 1703247 wird ein Radarabschirmendes textiles Material beschrieben, welches mindestens zweilagig ist sowie eine Distanzschicht aufweist. Das vorgeschlagene Gewebe ist relativ aufwendig, insbesondere in der Herstellung, sowie relativ schwer.In the EP 1703247 a Radarabschirmendes the textile material is described, which is at least two-ply and has a spacer layer. The proposed fabric is relatively expensive, especially in the production, and relatively heavy.

Es ist daher eine Aufgabe der vorliegenden Erfindung, eine Massnahme zur Tarnung von Objekten und/oder Personen gegen Erkennung durch Radar vorzuschlagen.It is therefore an object of the present invention to propose a measure for camouflaging objects and / or persons against detection by radar.

Erfindungsgemäss wird eine Vorrichtung gemäss dem Wortlaut nach Anspruch 1 vorgeschlagen.According to the invention, a device according to the wording of claim 1 is proposed.

Es hat sich gezeigt, dass überraschenderweise Beschichtungen auf Basis der neuerdings bekannten sogenannten ICP-Polymeren (intrinsically conductiv polymers) verwendet werden können, um einen ähnlichen Effekt zu erzielen wie bei Verwendung von herkömmlichen Polymeren, welche als Füllstoffe Metallfasern oder Metallpulver enthalten.It has been found that, surprisingly, coatings based on the newly known so-called ICP polymers (intrinsically conductive polymers) can be used in order to achieve a similar effect as when using conventional polymers which contain metal fibers or metal powders as fillers.

Mit anderen Worten wird erfindungsgemäss vorgeschlagen ein Gewirk oder Gewebe, wie es heute allgemein üblich für Tarnzwecke verwendet wird, mit einer Beschichtung auf Basis eines sogenannten ICPs wie insbesondere von Polythiophene zu versehen.In other words, according to the invention, it is proposed to provide a knit or fabric, as is generally used today for camouflage purposes, with a coating based on a so-called ICP, such as, in particular, polythiophene.

Als ICPs kommen Polymere auf Basis von Polyanalin, Polypyrrol oder Polythiophene in Frage, wobei diese leitenden Polymere in der Regel auf Basis von Lösungen oder Dispersionen im Markt erhältlich sind. Angeboten werden diese Polymere bzw. Lösungen oder Dispersionen davon von unter anderem Ormecon GmbH in Ammersbeck; Panipol, Finnland; DSM, Holland; BASF AG, Ludwigshafen und H.C. Starck GmbH, Leverkusen, um nur einige zu nennen.Suitable ICPs are polymers based on polyanaline, polypyrrole or polythiophene, these conductive polymers generally being obtainable on the basis of solutions or dispersions on the market. These polymers or solutions or dispersions thereof are offered by inter alia Ormecon GmbH in Ammersbeck; Panipol, Finland; DSM, Holland; BASF AG, Ludwigshafen and H.C. Starck GmbH, Leverkusen, just to name a few.

Als Tarnmaterialen können Gewebe oder gewirkte Textilien verwendet werden, wie beispielsweise auf Basis von Polyestern, Polyamid, Aramid (aromatische Polyamide) sowie Polypropylen oder Mischgewebe aus den genannten Materialen.As camouflage materials woven or knitted textiles may be used, such as based on polyesters, polyamide, aramid (aromatic polyamides) and polypropylene or blended fabric of the materials mentioned.

Das vorgeschlagene Tarnmaterial ist auf einer Wirkware oder einem offenen Gewebe aufgebaut. Zur Abschirmung von Radarbereichen von 8 bis 12 GHz können zusätzlich Metallfäden wie beispielsweise auf Basis Konstantan oder Silber in einem Abstand von ca. 3 bis 5 mm in das Textil eingearbeitet werden, horizontal und vertikal bzw. Kette und Schuss.The proposed camouflage material is constructed on a knitted fabric or an open fabric. For shielding radar ranges from 8 to 12 GHz, metal filaments, such as, for example, based on constantan or silver, can also be incorporated into the textile at a distance of about 3 to 5 mm, horizontally and vertically, or warp and weft.

Zur Erhöhung der Abschirmung wird vorgeschlagen das Gewebe wie oben erwähnt mittels zusätzlich einer Beschichtung zu versehen.To increase the shield is proposed to provide the tissue as mentioned above by means of an additional coating.

Die Beschichtung des Gewebes oder Gewirkes kann mittels üblichen Beschichtungsmethoden erfolgen, wie Aufsprühen, Auftragen mittels eines Rakels, Tauchen in ein Tauchbad, etc. Dabei können den handelsüblich erhältlichen Dispersionen oder Lösungen der genannten leitenden Polymere weitere Additive beigefügt werden, wie Benetzungsmittel, Verdicker, Dispergiermittel, Lösungsmittel, UV-Stabilisatoren, Farbpigmente, Flammschutzmittel, Vernetzungsmittel um die Wasser- und Lösungsbeständigkeit der schlussendlichen Beschichtung zu erhöhen, etc.The coating of the fabric or knitted fabric can be effected by means of customary coating methods, such as spraying, application by means of a doctor blade, immersion in a dipping bath, etc. The commercially available dispersions or solutions of said conductive polymers may be accompanied by further additives, such as wetting agents, thickeners, dispersants , Solvents, UV stabilizers, color pigments, flame retardants, crosslinking agents to increase the water and solution resistance of the final coating, etc.

Je nach zu erzielender Leitfähigkeit der Beschichtung ist es zudem möglich weitere, die Leitfähigkeit zu erhöhende Additive, wie Kohlenstofffasern, Metallfasern, etc. der zu beschichtenden Formulierung beizufügen.Depending on the conductivity of the coating to be achieved, it is also possible to add further additives to be increased in conductivity, such as carbon fibers, metal fibers, etc., to the formulation to be coated.

Die zu applizierende Formulierung ist je nach verwendetem Gewebe oder Gewirk anzupassen, wie auch in Bezug der zu erzielenden Leitfähigkeit bzw. Fähigkeit der Abschirmung gegenüber Radarstrahlung.The formulation to be applied is to be adapted depending on the fabric or knitted fabric used, as well as with regard to the conductivity or capability of the shielding against radar radiation to be achieved.

Das erfindungsgemäss hergestellte, beschichtete Tarnmaterial kann für beliebigen Einsatz, insbesondere zu militärischen Zwecken, verwendet werden, wo Objekte, Personen oder Tiere gegen Radarerkennung zu schützen sind. Seien dies Fahrzeuge, Gebäude, schwere Waffen oder verwendet als Tarnanzüge für Truppenverbände.The coated camouflage material produced according to the invention can be used for any purpose, in particular for military purposes, where objects, persons or animals are to be protected against radar detection. Be it vehicles, buildings, heavy weapons or used as camouflage suits for troops.

Selbstverständlich ist es vorteilhaft, wenn das verwendete Tarnmaterial durch entsprechende Farbgebung bzw. Oberflächenstrukturierung mit den heute üblichen und bekannten Tarnmuster bzw. Tarnfarbgebungen versehen ist, um zusätzlich eine gute Tarnung gegenüber visuelle Erkennung zu gewährleisten. Zudem ist es vorteilhaft, wenn das verwendete Gewebe bzw. Gewirk eine gewisse optische Transparenz aufweist, in der Grössenordnung von ca. 10 bis 40%, vorzugsweise 15 bis 35%.Of course, it is advantageous if the camouflage material used is provided by appropriate coloring or surface structuring with the camouflage patterns or camouflage colors customary today and in order to additionally ensure good camouflage vis-a-vis visual recognition. In addition, it is advantageous if the woven or knitted fabric used has a certain optical transparency, of the order of magnitude of approximately 10 to 40%, preferably 15 to 35%.

Erfindungsgemäss hergestellte Tarnmaterialien weisen so schliesslich eine Leitfähigkeit auf, in der Grössenordnung von ca. 300 Ohm/sq bis zu 35kg Ohm/sq.Finally, camouflage materials prepared according to the invention have a conductivity of the order of about 300 ohms / sq to 35 kg ohms / sq.

Wie bereits oben erwähnt ist das vorgeschlagene Tarnmaterial auf einer Wirkware oder einem offenen Gewebe aufgebaut. Zur Abschirmung im Radarbereich von 8 bis 12 GHz sind vorzugsweise Metallfäden wie beispielsweise auf Basis Konstantan oder Silber in einem Abstand von 3 bis 5 mm in das Textil eingearbeitet. Die Wirkung dieser Fäden ist in den Abbildungen 1 und 2 dargestellt. Wie insbesondere auf Abbildung 2 zu ersehen ist zeigt diese Anordnung bei sehr hohen Frequenzen wenig Wirkung. Deswegen wird das Gewebe zusätzlich, wie Erfindungsgemäss vorgeschlagen, noch mit einem leitfähigen Material wie auf Basis von Polythiophene beschichtet. Die Wirkung dieser Beschichtung ist in den Abbildungen 3 und 4 dargestellt. Die Oberflächenleitfähigkeit soll ca. 1000 Ohm/sq betragen. Die Wirkung dieser Beschichtung ist unter Auslassung des sogenannten Skineffektes über die Frequenz unabhängig. Wie in dem Artikel z.B. " Simple Formulas for estimating the microwave shielding effectiveness of EC-coated optical windows",Claude A. Klein, SPIE Volume 1112, Window and Dome Technologies and Materials, 234 (1989 ) beschrieben, nimmt die Abschirmwirkung aufgrund des Skineffektes bei dünnen Schichten mit zunehmendem Oberflächenwiederstand stark ab. Deshalb wird mit einer solchen Schicht bei 10 GHz nur eine geringe Wirkung erzielt, bei 94 GHz jedoch wird die Wirkung wie in Abbildung 4 dargestellt erreicht. Durch Kombination vom Einbau von dünnen Fäden in einem offenen Gewebe bzw. Wirkware und Beschichtung mit Leitfähigen Materialien kann ein Material hergestellt werden, welches über einen grossen Frequenzbereich Mikrowellen optimal abschirmt. Der Vorteil dieser Methode gegenüber dem Einsatz einer leitfähigen Schicht mit sehr viel geringerem Oberflächenwiderstand liegt im sparsameren Einsatz der sehr kostspieligen leitfähigen Polymere.As already mentioned above, the proposed camouflage material is constructed on a knitted fabric or an open fabric. For shielding in the radar range of 8 to 12 GHz preferably metal threads such as based on constantan or silver at a distance of 3 to 5 mm are incorporated into the textile. The effect of these threads is shown in Figures 1 and 2. As in particular Figure 2 As can be seen, this arrangement shows little effect at very high frequencies. Therefore, the fabric is additionally, as proposed in the invention, nor with a conductive material such as based on polythiophene coated. The effect of this coating is shown in Figures 3 and 4. The surface conductivity should be about 1000 ohms / sq. The effect of this coating is independent of the frequency, omitting the so-called skin effect. As in the article eg " Simple Formulas for estimating the microwave shielding effectiveness of EC-coated optical windows ", Claude A. Klein, SPIE Volume 1112, Window and Dome Technologies and Materials, 234 (1989 ), the shielding effect due to the skin effect in thin layers with increasing surface resistance decreases sharply. Therefore, with such a layer, only a small effect is achieved at 10 GHz, but at 94 GHz, the effect is as in Figure 4 achieved reached. By combining the incorporation of thin threads in an open fabric or knitted fabric and coating with conductive materials, a material can be produced which optimally shields microwaves over a wide frequency range. The advantage of this method over the use of a conductive layer with much lower surface resistance is the more economical use of the very expensive conductive polymers.

Anhand eines nachfolgend beschriebenen Ausführungsbeispiels soll die vorliegende Erfindung beispielsweise näher erläutert werden.Reference to an embodiment described below, the present invention will be explained in more detail, for example.

Verwendet wurde ein Tarnnetz, basierend auf einem Polyestergewebe oder einem Aramidgewebe mit einem Gewicht von 120 bis 150gr/m2.A camouflage net was used based on a polyester fabric or an aramid fabric having a weight of 120 to 150 g / m 2 .

Für die Beschichtung verwendet wurde eine Dispersion der Firma Agfa-Gevaert Ltd. mit der Bezeichnung Orgacon S300, d.h. auf Basis von Polyethylendioxythiophon (PEDOT).The coating used was a dispersion from Agfa-Gevaert Ltd. with the designation Orgacon S300, ie based on Polyethylendioxythiophon (PEDOT).

Vor der Beschichung mittels Polyethylendioxythiophon wird das Textil vorzugsweise mit einer dünnen Polyurethanbeschichtung überzogen. Diese Vorbeschichtung schliesst etwas die Oberfläche und sorgt dafür, dass im nachfolgend beschriebenen Tauchbad weniger PEDOT vom Textil aufgenommen wird.Before coating by means of Polyethylendioxythiophon the textile is preferably coated with a thin polyurethane coating. This pre-coating closes the surface slightly and ensures that less PEDOT is absorbed by the textile in the immersion bath described below.

Die Beschichtung des Polyestergewebes oder des Aramitgewebes erfolgte mittels Tauchbeschichtung in einem Bad auf Basis von Orgacon S300 gelöst bzw. dispergiert in folgender Zusammensetzung: N-Methyl-2-2pyrrolidon 5-10% Diethylen-Glykol 1-5% 2-Heptadecylbenzimidazole-4sulfonsäure 0.5-1% dazu: Wasser 60-80% Styrol/butyl/acrylat-copolymer 1-5% Polymethylmethacrylat 1-5% Silica (Kieselsäure) 0.5-1% The coating of the polyester fabric or the Aramitgewebes was carried out by dip coating in a bath based on Orgacon S300 dissolved or dispersed in the following composition: N-methyl-2-2pyrrolidon 5-10% Diethylene glycol 1-5% 2-Heptadecylbenzimidazole-4sulfonsäure 0.5-1% to: water 60-80% Styrene / butyl / acrylate copolymer 1-5% polymethylmethacrylate 1-5% Silica (silica) 0.5-1%

Die Beschichtung erfolgt im oben genannten Bad gemäss allgemein bekannt üblichen Tauchbeschichtungsverfahren, wobei vorzugsweise die Beschichtung zweifach im Tauchverfahren erfolgt. Der Verbrauch dieser Lösung ergibt ca. 2 x 145ml/m2 Gewebes.The coating takes place in the abovementioned bath in accordance with the generally known dip-coating method, the coating preferably taking place twice in the dipping process. The consumption of this solution gives about 2 x 145ml / m 2 tissue.

Zusätzlich für die Beschichtung können folgende Chemikalien verwendet werden:

  • Urepol (Polyurethan)
  • Ammoniak
  • Flammschutzmittel
  • Dispergiermittel
  • Flammschutzmittel
  • und gegebenenfalls Verdicker (nicht unbedingt nötig)
Additionally for the coating the following chemicals can be used:
  • Urepol (polyurethane)
  • ammonia
  • Flame retardants
  • dispersants
  • Flame retardants
  • and optionally thickener (not absolutely necessary)

Das so mit Orgacon getränkte bzw. beschichtete Polyestergewebe wurde leicht abgequetscht und beispielsweise bei 160°C mittels Heissluft oder -strahler während ca. 120 sec. getrocknet, wobei durch die Verwendung beispielsweise eines Vernetzungsmittels eine zusätzliche Vernetzung in der Beschichtung stattfinden kann.The so impregnated with Orgacon or coated polyester fabric was easily squeezed and dried, for example, at 160 ° C by means of hot air or radiator for about 120 sec., With the use of, for example, a crosslinking agent can take place an additional crosslinking in the coating.

Zur gleichzeitigen Flammschutzausrüstung sind ca. 100g/l Flammschutz (beispielsweise zyklische Phosphorverbindung) und ca. 5g/l Ammoniak notwendig (Flammschutz bewirkt einen deutlich weicheren Griff). Dabei muss die Temperatur auf ca. 190-200°C erhöht werden, um ein Diffundieren des Flammschutzes in die Polyesterfaser zu erreichen.For simultaneous flame retardancy, approx. 100g / l flame retardancy (eg cyclic phosphorus compound) and approx. 5g / l ammonia are necessary (flame retardation causes a much softer feel). In this case, the temperature must be increased to about 190-200 ° C in order to achieve a diffusion of the flame retardant in the polyester fiber.

Sollte ein etwas stabilerer Griff erzielt werden sind 50-100g/l Polyurethan-Dispersion und ca. 10g/l Melamin einzusetzen. Dieser Zusatz an Polyurethan reicht ebenfalls aus, um beispielsweise das Aufbringen bzw. Ankleben von Farbstoffen zu unterstützen.If a slightly more stable grip is achieved use 50-100g / l polyurethane dispersion and approx. 10g / l melamine. This addition of polyurethane is also sufficient to support, for example, the application or sticking of dyes.

Eine geringe Viskositätserhöhung bewirkt ein besseres Wasserrückhaltevermögen.A small increase in viscosity causes a better water retention.

Anschliessend an die Beschichtung wurde die Effizienz gegen Radarstrahlung des erfindungsgemäss hergestellten Tarnmaterials gemessen und ergab ein reflektiertes Radarsignal, bezogen auf eine Metallplatte (0:100% Reflektion, -18db: 1,6% Reflektion)Subsequent to the coating, the radar radiation efficiency of the camouflage material produced according to the invention was measured and yielded a reflected radar signal, based on a metal plate (0: 100% reflection, -18 dB: 1.6% reflection).

Die Messung ist der beigefügten Figur 5 im dargestellten Diagramm zu entnehmen.The measurement is attached FIG. 5 to take in the diagram shown.

Grundsätzlich ist auszuführen, dass die Beschichtung des Gewebes oder Gewirkes mittels irgendeines bekannten Beschichtungsverfahren erfolgen kann, wie insbesondere mittels eines Tauchverfahrens. Mit anderen Worten handelt es sich bei den Beschichtungs- bzw. dem beschriebenen Tauchverfahren um allgemein üblich bekannte Verfahren zum Beschichten von beispielsweise textilen oder nicht textilen Geweben bzw. Gewirken.In principle, it should be stated that the coating of the fabric or knitted fabric can be effected by means of any known coating method, in particular by means of a dipping method. In other words, the coating process or the dipping process described is generally known processes for coating, for example, textile or non-textile fabrics or knitted fabrics.

Die vorliegende Erfindung ist selbstverständlich keinesfalls auf einfache Gewebe beschränkt, wie sie üblicherweise für Tarnnetze verwendet werden, sondern die Beschichtung mittels eines elektrisch leitenden Polymers kann für irgendein textiles bzw. technisches Gewebe oder Gewirk angewendet werden, wie beispielsweise auch für sogenannte zweilagige, dreidimensionale Gewirke bzw. Raschelware. Es hat sich beispielsweise gezeigt, dass durch die Verwendung von sogenannten zweilagigen Geweben bzw. Gewirken die radarabschirmenden Eigenschaften durch den zwischen den Lagen ausgebildeten Zwischenraum erhöht werden kann.Of course, the present invention is by no means limited to simple fabrics such as are commonly used for camouflage nets, but the coating by means of an electrically conductive polymer can be applied to any textile or knit fabric, such as so-called two-ply, three-dimensional knits or knit fabrics Raschelware. It has been found, for example, that the radar-shielding properties can be increased by the use of so-called two-ply fabrics or knitted fabrics by the intermediate space formed between the layers.
