Definitions

  • the invention relates to a heat tarpaulin according to the preamble of claim 1.
  • camouflage nets For military camouflage of fixed and mobile military equipment, such as motor vehicles, tanks and the like, camouflage nets are used.
  • the camouflage nets should generate not only a camouflage in front of infrared cameras or thermal imaging detectors, but also before radar detection.
  • the camouflage net is intended to prevent microwaves impinging on an object from being reflected back by it. Furthermore, it should be prevented that an identification by sensors in the infrared or thermal imaging is possible.
  • a camouflage net in a certain material composition has a suitably adapted hole structure of the net to provide both visible and near infrared protection, good damping values to generate a broad spectrum of the microwave range and to be low imitating in the thermal image area (see eg DE 40 23 287 C2 ).
  • Such camouflage nets generally serve their purpose.
  • Camouflage becomes problematic, however, if a hot spot is present locally under the camouflage net, eg by the engine of a vehicle or else by a stationary engine. Due to the network structure, this local hot spot can be located in the infrared range, eg in the far infrared range.
  • tarpaulins are already known from practice, with which the hot spot is covered.
  • the known tarpaulins have various disadvantages, such as e.g. poor mechanical strength and a limited temperature range with the risk of combustion at too high a temperature. This means a limited handling for the rough practice operation.
  • the generic document describes a Wärmarnplane to cover heat sources, which has significant improvements in terms of the above-mentioned prior art.
  • the generic heat tarpaulin has on the side facing the object to be covered a coating with a silicone elastomer containing aluminum powder on.
  • the other side is provided with a silicone elastomer containing metal pigments whose reflectance values are within the range of visual-optical camouflage.
  • the heat tarpaulin is within a wide temperature range effective, at the same time given an improved mechanical strength and a high temperature resistance.
  • the surface of the heat tarpaulin coated by the silicone elastomer shines, thereby increasing the risk of detection.
  • a disadvantage is also that can not be adhered to the silicone elastomer coated surface of the heat tarpaulin article numbers.
  • the present invention is therefore an object of the invention to solve the above-mentioned disadvantages of the prior art, in particular to further improve the generic Wärmarnplane, so that the usefulness and storability of the Wärmarnplane is increased, as far as possible all occurring in nature colors are modeled can be achieved, largely values in the infrared corresponding to those of nature, as well as a matte surface is achievable.
  • the coating comprising color pigments ie the colored side of the heat tarpaulin facing away from the object to be covered, has a polyurethane coating (or polyurethane elastomers) or a polyvinylidene fluoride coating (or polyvinylidene fluoride), all the colors occurring in nature can be used Reproduce.
  • the generic Wärmarnplane could be generated due to the silicone elastomer coating only in a very limited color palette. Now it is possible, in addition to the usual green optics, which was used especially for use under Woodland camouflage nets, also one of the desert (sand color) or one of the Arctic (white) adapted to realize optics.
  • the heat tarpaulin according to the invention is incombustible. This means that it can be safely placed directly on hot spots.
  • the carrier textile is formed as a glass filament fabric, preferably as a cross twill.
  • the generic heat tarpaulin based warp knitted fabric had a, compared to the other prior art, already increased strength of 1,900 N / 5 cm in the warp and weft directions.
  • the invention Wärmarnplane based Buchköper 01 02 has a strength of 4,000 N / 5 cm in the warp and 3,000 N / 5 cm in the weft.
  • the coating containing aluminum powder is formed as a silicone elastomer coating and / or as a polyurethane coating.
  • the aluminum powder in combination with the silicone elastomers and / or the polyurethane ensures a correspondingly high heat radiation
  • the polyurethane or the polyvinylidene fluoride in conjunction with the color pigments ensures a reduction in recognition in the visible and in the infrared range.
  • the color pigments and the polyurethane coating or the Polyvinylidenfluoridbe Anlagenung can be achieved a surface color design that is adapted to the environment and / or a camouflage net lying above.
  • the coating containing aluminum powder and / or the color pigments is applied by means of a transfer coating method.
  • the advantage of the transfer coating process is that it does not directly coat the glass fibers. This results in a softer, more flexible material which is less susceptible to cracking. The surface becomes smoother as it is applied only superficially, yet the entire glass fiber is covered. In contrast to the principle also possible Direct coating creates no "valleys and heights" through the tissue.
  • the aluminum layer has an optical density of 2.9 to 3.5%. It has also proved to be advantageous if the coating of the aluminum side has a weight of 40 to 50 g / m 2 .
  • the carrier fabric is formed of warp knit fabric, wherein each a glass filament performing warp and a weft thread are bound to each other by means of a plastic thread system.
  • the warp knitted fabric can be designed so that the strength of fabric or a desired elasticity is achieved, with greater elasticity breaking the Sutextilie and thus wear of the heat tarpaulin is reduced.
  • the end property of the polyurethane elastomers can be tailored. If silicone elastomers are used instead of the polyurethane on the side provided with the aluminum powder, these may also be crosslinkable.
  • the color pigments admixed to the polyurethane or polyvinylidene fluoride on the other side should advantageously be selected such that 10 to 50% of color pigments, preferably 30% of color pigments, are contained on the outside in the polyurethane or polyvinylidene fluoride. Due to the color pigments and the polyurethane coating or the Polyvinylidenfluoridbe Anlagenung All colors occurring in nature can be reshaped in terms of appearance.
  • color pigments are present in the polyurethane or polyvinylidene fluoride, whose remission values are in the range light green to dark green, for which the color pigments may have metal pigments which preferably contain chromium oxides, which have been found to be particularly suitable.
  • a carrier textile which has a weight per unit area of 300 to 450 g / m 2 , preferably 400 g / m 2 .
  • the coating should have a weight of 70 to 80 g / m 2 ,
  • the edges of the heat tarpaulin are sealed with cold-crosslinking polyurethane.
  • the heat tarpaulin invention is made up in a prescribed size.
  • the heat tarpaulin is cut conventionally.
  • fraying the heat tarpaulin is prevented. In a particularly advantageous manner, this avoids frayed light spots of the coating containing aluminum powder or uncoated areas of the inside of the fiber from escaping to the outside and thus adversely affecting discoverability.
  • Wärmarnplanen are already well known in terms of their purpose and in terms of their basic structure as knitted or warp knitted fabric and as a fabric, including on the DE 297 16 362 Reference is made, therefore, only the essential features of the invention will be described in more detail below.
  • a carrier textile 1 which is formed as a glass filament fabric in a twill weave, preferably as a cross twill with a basis weight of 400 g / m 2 is used.
  • Fig. 2 In this case, the vertical columns of the binding cartridge shown represent the warp threads 2, the horizontal rows of weft threads 3.
  • the warp thread 2 When the warp thread 2 is on the surface, which is in Fig. 2 filled field of the binding cartridge filled when the weft yarn 3 is on top, the field is empty.
  • carrier fabric 1 has on the side facing away from the object to be covered, namely the outside, which is directed upward, a polyurethane coating 4.
  • the outside is provided with the polyurethane coating 4 in the direct coating process or transfer coating process.
  • the polyurethane coating 4 is a proportion of 10 to 50% of color pigments 5, preferably 30% of color pigments 5, admixed.
  • the color pigments 5 in this case have metal pigments, not shown, which may contain chromium oxides.
  • the polyurethane coating 4 may, for example, have a basis weight of 30 to 90 g / m 2 .
  • a formation of the metal pigments as chromium oxides is particularly advantageous if good remission values in the range from light green to dark green and thus camouflage in the visible and in the near infrared should be achieved.
  • the remission values may be dark green color e.g. at 400 nm 8, at 550 nm 10, at 600 nm 8, at 650 nm 8, at 750 nm 37, at 800 nm 46, at 1200 nm 44 and at 1800 nm 44.
  • the large increase at 750 nm is called chlorophyll jump and is modeled on the behavior of deciduous trees in this wave range.
  • carrier fabric 1 is also coated on the object to be covered facing side with a polyurethane coating 6, the 15 to 40 weight percent aluminum powder 7 is mixed.
  • the polyurethane coating 6 can also be applied by direct coating.
  • a crosslinkable polyurethane coating 6 is particularly suitable.
  • the polyurethane coating 4 may be formed as a crosslinkable polyurethane coating.
  • the polyurethane coating 6 provided with the aluminum powder 7 may, in an alternative embodiment, also be embodied as a silicone elastomer coating provided with aluminum powder 7, since on this side of the carrier textile 1 the reflectance alone is significant.
  • the reflection values of the heat tarpaulin according to the invention are in the range of 0.4 to 2.5 nm over 50%.
  • the silicone elastomer used instead of the polyurethane coating 6 can also be applied by direct coating and be formed as a crosslinkable silicone elastomer.
  • crosslinker a hydrogenpolysiloxane having a high content of reactive Si-H can be used. 2% by weight are mixed with the silicone elastomer.
  • the vulcanization should be heated to approx. 150 ° for a period of three minutes.
  • the vulcanization time depends on the temperature used. This means that at higher temperatures results in a lower vulcanization time and vice versa.
  • the heat tarpaulin can be exposed to a temperature range of more than 1,000 ° C for several minutes without damaging it, resulting in the heat tarpaulin is practically incombustible.
