Definitions

  • the invention relates to a composite tarpaulin with a waterproof, preferably flexible outer layer, an inner layer and a spacer material arranged between the inner layer and the outer layer.
  • the invention further relates to a tent arrangement with a supporting structure and the composite tent tarpaulin described above, which is held by the supporting structure.
  • tarpaulins of films and fabrics are known, which are essentially intended as a waterproof outer skin.
  • Such tarpaulins are characterized by a low weight and can also be very compact folded or rolled up.
  • a thin coating is provided only on one side of the spacer fabric, which is windproof and waterproof. This coating does not contribute significantly to the stability of the tarpaulin. Only if the spacer textile is extremely close mesh, a significant heat transfer can be avoided by convection, but then a correspondingly high basis weight of the spacer textile must be taken into account.
  • a metallization is attached to at least one side of the spacer fabric.
  • the spacer fabric provided on both sides with a thin film can be joined to another textile, so that this further textile then forms a surface whose resistance is in need of improvement.
  • the present invention has for its object to provide a composite tarpaulin, which is characterized by a particularly high resistance, an insulating effect and good handling. Furthermore, a tent arrangement is to be specified with such a composite tent.
  • the object of the invention and solution of the problem are a composite tent according to claim 1 and a tent arrangement according to claim 17.
  • the outer layer and the inner layer have a thickness ratio of at least 2: 1, wherein the outer layer has a thickness between 200 ⁇ and 800 ⁇ and the inner layer has a thickness between 20 ⁇ and 200 ⁇ have, and that the spacer material has a thickness between 2 mm and 20 mm, in particular 2 mm to 10 mm.
  • the composite tarpaulin has an asymmetric layer structure, wherein the waterproof outer layer has at least twice the thickness of the inner layer.
  • the outer layer thus serves not only a watertight closure, but also significantly to an increase in the total
  • the outer layer is preferably a flexible, relatively thick outer film, which may readily be a fabric film and / or a fiber-reinforced film.
  • the composite tarpaulin obtains its stability mainly through the outer layer and the spacer textile, whereby it is precisely the composite properties of the different materials that can be optimally utilized. Due to the specified layer thickness of at least 200 ⁇ and at most 800 ⁇ the outer layer already has a good stability and resistance on its own. By the spacer material, the total load capacity can be further increased, with just the spacer material is also suitable to achieve a uniform force distribution and to distribute, for example, selective forces on a larger area.
  • the spacer material is preferably flexible and more preferably also has gaps filled with air or another gas, thereby resulting in an insulating effect.
  • the spacer material is also elastic in the direction of its thickness, in order to be able to be deformed on the one hand without being impaired and, on the other hand, to be set up again after a loss of force.
  • the spacer material may, for example, be a foam, a non-woven fabric or preferably a spacer textile.
  • the density of the spacer material is preferably below 0.5 g / cm 3 , more preferably below 0.2 g / cm 3 , wherein the density refers to the total extent of the spacer material.
  • the specified density refers to the total volume occupied by the spacer material (including the voids) and not to the density of the particular polymer.
  • both closed cavities and interconnected cavities may be present.
  • interconnected cavities results in a structure similar to a sponge.
  • convection of gas in the spacer material can be largely avoided, resulting in particularly advantageous elastic properties.
  • the spacer material made of nonwoven is to be noted that a layer separation within the web must be avoided even under load of the composite tarpaulin. It is therefore to select a fleece, which already has sufficient strength by its production.
  • the strength of a nonwoven fabric can be increased, for example, by needling or twisting of the individual fiber types by means of water jets.
  • regions and / or embossings for solidification may also be provided in regions, such regions having an increased strength being able to be punctiform or linear in shape without limitation.
  • the basis weight is preferably between 100 and 500 g / m 2 .
  • the spacing material used is preferably a spacer textile, which will be explained further below.
  • the spacer fabric initially causes an insulation, because between the outer layer and the inner layer, an insulating air cushion is formed. Due to the elastic properties of the spacer textile, the composite tarpaulin remains well deformable despite the multi-layered construction.
  • the material can also be rolled up and folded, because the comparatively thin inner layer and the
  • the properties described also cause some protection of the comparatively thick-walled outer layer against accidental buckling during handling.
  • the inner layer can contribute to some extent to the bond strength, the main function is to avoid convection on the inside and thus protect the insulating layer of air inside the spacer fabric from exchange with the environment.
  • the inner layer does not necessarily have to be completely impermeable.
  • textiles into consideration.
  • an airtight finish can optionally be achieved by means of a plastic coating.
  • a coating can be formed, for example, based on acrylate, polyurethane (PUR), silicone or a mixture of the materials mentioned.
  • the inner layer can also be designed as a coating, for which purpose the abovementioned materials can be applied directly to the corresponding textile layer. Furthermore, it is also possible to extrude thermoplastic material directly onto the corresponding textile layer.
  • plastic tapes may then either strip-like in the outer layer or preferably be woven together, which then usually crosses a first group of plastic tapes at a right angle with a second group of plastic tapes. Stretched plastic tapes are characterized by a very high load capacity, with a fabric structure and individual local damage can not lead to a continuous crack.
  • a fabric of plastic tapes can be provided in the outer layer one or more layers.
  • a fabric formed from stretched plastic tape can be compacted under the action of pressure and temperature and thereby fused to some extent, be provided by extrusion lamination with a further film layer and / or laminated with at least one further film layer.
  • the measures described not only the tightness of the outer layer is guaranteed.
  • a closed and relatively smooth surface is formed, which can also be easily cleaned.
  • the outer layer is not only in all circumstances tight against rain, but also easy to clean with water, for example, a high-pressure cleaner.
  • the outer layer should be flexible to some extent, preferably also a rolling or
  • Wrinkles should be possible.
  • the composite tent sheets in the form of individual flexible panels which are then suitably connected to one another in a tent arrangement.
  • a material web made of plastic is suitable, which has stretched ribbons, in particular highly stretched ribbons of polypropylene and / or polyester.
  • stretched ribbons in particular highly stretched ribbons of polypropylene and / or polyester.
  • such ribbons preferably woven together, can be superficially melted at a suitable temperature and pressed together. The temperature during the pressing is adjusted so that the polymer does not melt completely and the structure of the polymer chains achieved by stretching the ribbons is at least largely retained.
  • Suitable materials are available under the brand name Curv®.
  • the preparation of a particularly suitable polymer film material is described, for example, in EP 1 453 647 B1.
  • fiber reinforcement may also be provided.
  • at least one layer of the outer layer may contain carbon fibers, mineral fibers such as glass fibers, polymer fibers, natural fibers or the like.
  • the outer layer may preferably also have at least one filler selected from the group of color pigments and UV stabilizers.
  • Color pigments control the absorption of sunlight. For example, heating can be minimized by a white batch such as titanium dioxide.
  • UV stabilizers may be useful to avoid decomposition of the polymer chains by sunlight during long-term use.
  • the inner layer and the outer layer may also contain other fillers in order to influence the mechanical properties or to reduce the material costs.
  • the outer layer and / or the inner layer may also have a metallization. If the outer layer or the inner layer are laminated multilayered, such a metallization can also be arranged protected within the respective layer.
  • reflecting particles for example aluminum particles, can also be integrated into individual layers of the outer layer and / or the inner layer as a type of color pigment as described above during extrusion.
