Definitions

  • 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.
  • 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 based on ferrite, such as carbonyl iron ferrite.
  • 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.
  • ICP polymers intrasically conductive polymers
  • 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, Agfa-Gevaert NV, Mortsel, Belgium, just to name a few.
  • 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.
  • 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 dip bath, etc.
  • further additives can be added to the commercially available dispersions or solutions of said conductive polymers, such as wetting agents, thickeners, dispersants , Solvents, UV stabilizers, Color pigments, flame retardants, crosslinking agents to increase the water and solvent resistance of the final coating, etc.
  • 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.
  • 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.
  • 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.
  • 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%.
  • camouflage materials produced according to the invention have a conductivity of the order of about 300 ohms / sq to 35 k ohms / sq.
  • a camouflage net was used based on a polyester fabric or an aramid fabric having a weight of 120 to 150 g / m 2 .
  • the coating used was a dispersion from Agfa-Gevaert Ltd. labeled Orgacon S300, i. based on polyethylenedioxythiophone (PEDOT)
  • 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-4sulfonklare 0.5-1% to: water 60-80% Styrene / butyl / acrylate copolymer 1-5% polymethylmethacrylate 1-5% Silica (silica) 0.5-1%
  • 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.
  • the temperature must be increased to about 190-200 ° C in order to achieve a diffusion of the flame retardant in the polyester fiber.
  • polyurethane dispersion 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.
  • 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).
  • the measurement can be taken from the attached FIG. 1 in the diagram shown.
  • 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.
  • the coating process or the dipping process described is generally known processes for coating, for example, textile or non-textile fabrics or knitted fabrics.
  • 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.
