Definitions

  • the invention relates to a multilayer composite material with at least one layer formed by a film or film and at least one textile layer made of fibers.
  • Multilayer composite materials of the type mentioned at the outset are known and are used for simultaneous heat and / or sound insulation by means of a textile layer of fibers and at the same time sealing against moisture by means of a layer formed by a film or film.
  • a disadvantage of the known multilayer composite materials is that if the layer formed by a film or film is damaged, for example in the event of improper assembly or other mechanical influences, moisture can penetrate and this moisture penetrates the textile layer of fibers and in the long term leads to damage and Impairments such as rotting and / or frost damage.
  • a further disadvantage is that, depending on the amount of liquid that has entered, it passes through the textile layer, so that moisture protection is no longer guaranteed if the layer formed by a film or film is damaged.
  • the object of the invention is to improve a multilayer composite material of the type mentioned in such a way that, if the layer formed by a film or film is damaged, for example in the form of a Hole or a crack in this layer reliably prevents moisture from penetrating through the composite material.
  • This object is achieved according to the invention in that a multilayer composite material with at least one layer formed by a film or film and at least one textile layer made of fibers is further developed such that absorption particles are deposited and / or in the textile layer between and / or on the textile fibers are stored.
  • absorption particles are deposited and / or embedded between and / or on the textile fibers, the moisture entering the layer formed by a film or film is absorbed without the moisture entering it being able to wet the textile layer. This reliably prevents moisture from passing through the textile layer.
  • the absorptive particles attached or incorporated are preferably so-called superabsorbers, in particular polymers made of hydrophilic polymer chains. These have the property of binding liquid as a gel and can store many times their own mass of water. The water stored in the absorption particles is released back into the environment at a correspondingly low vapor pressure. The absorption and dispensing of liquid by the absorption particles is a reversible process.
  • the superabsorbent can store 30 times its own volume of liquid, or even 500 times for demineralized water.
  • the absorption particles can be in powder form, in particle form, in fiber form or as a mixture thereof.
  • the term absorption particle encompasses all different possible manifestations.
  • the textile layer (s) is a nonwoven, spunbond or fine fiber spunbond (meltblown) or a combination thereof.
  • the textile layer in particular meltblown, serves as a buffer due to its softness and flexibility.
  • the number of absorption particles per unit volume of the textile layer is constant. This uniform distribution of the absorption particles in the textile layer ensures constant material properties with regard to the ability to absorb and store moisture.
  • the number of absorption particles per unit volume of the textile layer increases in the direction of the film. This makes it possible to determine the material properties, i.e. the ability of the textile layer to absorb and store moisture in such a way that the ability to absorb and store moisture is greatest where the risk of moisture entry increases as a result of damage to the film.
  • At least one film of the multilayer composite material is preferably liquid-tight.
  • At least one film of the multilayer composite material is preferably vapor-tight.
  • At least one film of the multilayer composite material is vapor-permeable. This makes it possible to adapt the multilayer composite material as required to the fields of application and requirements, for example by providing a liquid-tight film to prevent the ingress of liquid, but on the other hand allowing vapor diffusion, which is essential for regulating the moisture content of the air.
  • ceramic particles and / or flying dust are applied to the outside of at least one film or film.
  • Ceramic particles can be applied as so-called ceramic bubbles, that is, vacuumized hollow spheres.
  • Airborne dust is a waste product from coal-fired power plants, and there are two types of airborne dust. On the one hand, fly dust from power plants with dry combustion using of lignite, producing glass spheres that are enriched with up to 50% carbon. These are solid spheres with a particle size of up to one millimeter, predominantly in the range 0.2 to 0.3 mm and the melting point is 1600 degrees Celsius. There is also flying dust from coal-fired power plants with smelting furnaces. This type of firing primarily burns hard coal.
  • Almost pure glass ball dust is produced in the form of hollow spheres (silicates, alkali silicates). Its grain size is much finer compared to the first-mentioned fly dust from power plants with dry combustion with a particle size of up to 20 micrometers. The melting point is also around 1600 degrees Celsius.
  • glass ball dust from the production of glass wool can be applied on the outside to at least one film or film. By applying these substances, depending on the spherical shape, different properties of the multilayer composite material are made possible.
  • a variable water vapor permeability can be achieved, ie the water vapor permeability can vary by a factor of 2 to 4 depending on the prevailing humidity climate.
  • a solar reflection of the multilayer composite material can be achieved with a high reflectance, in particular a reflectance of up to 0.84.
  • the application of ceramic particles and / or flying dust and / or glass ball dust can improve the UV resistance, the abrasion and the fire behavior.
  • the absorption particles preferably increase their volume with increasingly embedded moisture.
  • the leak is automatically sealed by the fact that the absorption particles in the immediate vicinity of the damage increase their volume in such a way that they damage the Close the area and prevent further moisture penetration.
  • the softness and flexibility of the textile layer in which the absorption particles are embedded or is ensured that the fiber composite of the textile layer and the layer composite of the different layers is not damaged by an increase in volume of the absorption particles as a result of moisture absorption, since this Changes in volume of stored absorption particles can be compensated for by the textile layer.
  • the textile layer in particular fine fiber spunbond layer (meltblown), is preferably hydrophilic and thereby ensures good and balanced moisture transfer or moisture distribution in the textile layer.

  • a layer 3 formed by a film 3 for sealing against moisture is applied to the outside of the fine fiber spunbonded nonwoven layer 2.
  • Absorbed particles 4 are embedded in the fine fiber spinning vias 2, with an even distribution, ie the number of absorbent particles 4 per Volume unit of the fine fiber spunbond layer 2 is constant. With this uniform distribution of the absorption particles 4 in the layer 2, constant material properties with regard to the ability to absorb and store moisture are ensured.
  • the representation is not to scale.
  • the absorption particles are actually powdery particles.
  • the absorption particles 4 are so-called super absorbers in the form of polymers in the form of hydrophilic polymer chains.
  • Ceramic particles 5 are applied to the outside of the film 3 in the form of so-called ceramic bubbles, i.e. in the form of vacuumized hollow spheres. This representation is also not to scale. These ceramic particles 5 increase the solar reflectance of the multilayer composite material when solar radiation is incident, indicated by the arrows 6A, 6B.
  • this damage 7 causes moisture to enter the multilayer composite material along the arrow 8.
  • This moisture which is introduced into the fine fiber spunbond layer 2 by the damage 7 in the film 3, is absorbed by the absorption particles 4 in the fine fiber spunbond layer 2, the absorption particles 4 changing their volume when absorbing moisture, indicated by the absorption particles 4A shown enlarged. Due to the increase in volume of the absorption particles 4 when absorbing moisture, the damaged area 7 of the film 3 is automatically sealed against the ingress of further moisture from below, by means of the increase in the volume of the absorption particles 4A.

  • FIG. 3 shows a third embodiment of the multilayer composite material according to the invention, which is formed in this exemplary embodiment by a base nonwoven 31, a microfiber nonwoven 32, a cover nonwoven 33 and a layer, not shown, of film which seals against moisture. Absorbed in the microfiber nonwoven layer 32 are absorption particles 4, which absorb moisture when there is a moisture input along the arrow 8 and increase their volume as a result of the moisture absorption, indicated by the absorption particles 4A after absorption of moisture.
