Definitions

  • the invention relates to a sound-absorbing and thermally insulating component of the type mentioned in claim 1.
  • a non-woven thermal insulation layer is on one side with a dimensionally stable support layer, e.g. a metallic or plastic part, and on the opposite side with an open-pore protective covering made of e.g. covered with a zinc alloy, which has low thermal insulation properties.
  • a sound insulation composite that can be used for automobiles is known (DE-A-41 31 394), of which a layer consists of an air-permeable nonwoven fabric with a basis weight of less than 200 g / m 2, which has a core layer of honeycomb-like cavities on one side and partitions connected and covered on the opposite side with a membrane film.
  • a layer consists of an air-permeable nonwoven fabric with a basis weight of less than 200 g / m 2, which has a core layer of honeycomb-like cavities on one side and partitions connected and covered on the opposite side with a membrane film.
  • a component is known (DE-A-38 41 187), in which the absorption layer is connected to a relatively thin, flexible barrier layer made of, for example, polypropylene to improve the sound-insulating properties.
  • a relatively thin, flexible barrier layer made of, for example, polypropylene to improve the sound-insulating properties.
  • sound-absorbing components are used in motor vehicles, for example, as floor pillar cladding in the interior.
  • the invention has for its object to improve a soundproofing component of the type mentioned in a simple manner in terms of its insulation and insulation properties. It is also desirable to use the soundproofing component, in particular for building construction and expand installations at this one. Another wish is that the component can be better disposed of.
  • the fleece of the absorption layer has a heat or cold insulation density between 5 and 150 kg / m3 in particular.
  • Nonwovens are textile composites that are not created by weaving or knitting, but by intertwining and / or by cohesive and / or adhesive bonding of textile fibers and / or by needling and / or by an air layer process (whirled up by air and then loosely layered Fibers, in particular with a preferred orientation) are produced.
  • the density or density is 5-40 kg / m3, in particular up to 20 kg / m3, while in an embodiment of the invention manufactured as a rigid press plate, the density or the Density between 10 and 150 kg / m3, in particular more than 50 kg / m3.
  • the fleece should have a thermal conductivity between 0.03 and 0.07 W / mK.
  • Polyester fibers which are formed from saturated linear aliphatic / aromatic polyesters or fibers made from PET (polyethylene terephthalate) or PBT (polybutylene terephthalate) are particularly preferably used for the nonwoven. Copolyester fibers and BIKO (bicomponent) fibers made from different polymers can also be used.
  • the invention is therefore particularly suitable for sound and thermal insulation of buildings, pipelines, systems, stationary machines and containers, including soundproof booths, as are preferably used in measuring rooms.
  • the present invention provides a good replacement for the currently. used mineral fiber products, which represents a significant improvement in production, application and disposal due to the carcinogenicity of mineral fibers.
  • the layer thickness of the component should be between 1 and 4 cm for impact sound insulation purposes, whereas thicker components between 2 and 50 cm are preferred for conventional thermal insulation purposes.
  • the layer thickness is largely determined by the fleece, whereas the barrier layer is comparatively thin with a thickness between 0.1 and 5 mm.
  • non-flammable fibers to the plastic fibers and, if appropriate, add flame-retardant particles, including in particular aluminum hydroxide with a particle size between 0.5 and 100 ⁇ m.
  • flame-retardant particles including in particular aluminum hydroxide with a particle size between 0.5 and 100 ⁇ m.
  • aluminum hydroxide as a flame-retardant finish is already known per se (rubber, asbestos, plastics, 1978, pages 863-866). It is understood that other flame retardant and fire retardant additives, such as phosphorus compounds, are applicable and the fleece can also be provided with such coatings on the surface, provided that the soundproofing properties are not significantly impaired.
  • the soundproofing component is equipped at least according to fire class B2.
  • the oleophobic and / or hydrophobic finishing of the fleece is recommended.
  • the use of herbicides and insecticides as surface protection or storage in the porous absorption layer is also suitable, provided that there are no disposal problems.
  • the barrier layer expediently also consists of polyester in the form of a film with a layer thickness between 0.1 and 1 mm.
  • a vapor barrier can also consist of metal, in particular an aluminum foil, and even of carrier papers, provided that these are sufficiently designed as vapor barriers. It is recommended to cover the fleece with the barrier layer on only one side.
  • a fleece 1 has more than 80%, in particular between 85 and 100%, polyester fibers PES with a fiber length of at least 5 mm.
  • the layer thickness is between 0.2 and 20 cm and the density or density is between 5 and 150 kg / m3.
  • the plastic fibers 1a made of PES are accordingly arranged in a substantially confused distribution.
  • the fleece 1 is covered on one side with a barrier layer 2 made of a polyester film with a layer thickness of 0.1 and 1.0 mm, which is shown partially raised in FIG. 1.
  • the barrier layer 2 can also be a lamination with a textile layer in order to promote the appearance and / or the fastening.
  • the combination of the fleece 1 with the barrier layer 2 serving as a vapor barrier serves as a roof insulation component instead of the previously used mineral wool and aluminum coating.
  • an edge 2a of the barrier layer 2 projects over the fleece 1 for connection to other components or to neighboring components.
  • the edge 2a can e.g. 2 to 10 cm wide.
  • the fleece 1 which has hollow plastic fibers 1 made of PES on the inside, is bendable in such a way that it is placed like a bandage on the outside around the pipe 3 as thermal and also sound-insulating insulation.
  • the winding material 10 collides at the joint 10a and for this purpose forms the annular jacket around the tube 3.
  • this tube jacket is designed as a molded part and can be laminated on the outside with an aluminum foil.
  • the fleece 1 is compressed much more strongly to a density or a density between in particular 50 and 150 kg / m3, so that a substantially rigid press plate 11 is formed, which is preferably used for impact sound insulation in the floor area of buildings and in addition to the plastic fibers 1a also contains flame-retardant particles 4 made of aluminum hydroxide.
  • the product is not hygroscopic; there are no corrosive or toxic combustion products in the event of a fire, so that even in the event of disposal there is no risk of environmental damage, although the pressure plate 11 is thereby designed to be flame-retardant in accordance with the conditions of fire class B2a.
  • a lamination layer made of textile layer parts is also attached to the fleece 1 as a barrier layer 2 with a projecting edge 2a.
  • the component according to the invention is used primarily as cavity sound insulation of e.g. Blind beams for wooden beam ceilings, stud walls, suspended ceilings, as an acoustic element, e.g. self-supporting decorative surfaces for grid ceilings, as a mobile soundproofing partition in e.g. Offices and used as intermediate barrier insulation.
  • cavity sound insulation e.g. Blind beams for wooden beam ceilings, stud walls, suspended ceilings
  • an acoustic element e.g. self-supporting decorative surfaces for grid ceilings
  • a mobile soundproofing partition in e.g. Offices and used as intermediate barrier insulation.
