Definitions

  • the invention relates to a mecanicnab Whylement for building.
  • the EP 2 349 707 B1 discloses a surface seal consisting of a Schott layer, a composite layer and a discontinuous between composite layer and Schott layer sealing means.
  • a Schott layer a flexible plastic film is used, while a felt or a nonwoven fabric is used as the composite layer.
  • the sealant is an adhesive or hot melt adhesive.
  • the fleece attached to the plastic film allows fresh concrete to partially penetrate.
  • the DE 692 13 507 T2 describes a surface seal with a carrier layer, on the entire surface of a pressure-sensitive adhesive layer is applied. On the adhesive layer, a fleece is arranged, which allows the fresh concrete to penetrate far enough to form a bond with the pressure-sensitive adhesive layer.
  • the present invention provides a surface sealing member for building.
  • Thecetnabêtlement has a flat carrier, wherein it is the sheet-like support is a plastic film, and arranged on the flat support, inseparably connected to the flat support, textile layer, wherein the textile layer is a nonwoven.
  • the textile layer is impregnated over its entire surface with a non-tacky adhesion promoter.
  • Thecetnabêtlement has a thickness I ⁇ 1.5 mm.
  • impregnation or “impregnation” is generally an infiltrating treatment of solid porous materials, such.
  • textiles, paper, wood or concrete with dissolved, emulsified or dispersed substances.
  • Such dissolved, emulsified or dispersed substances are referred to as impregnating agents.
  • the applied substances After evaporation or drying of the solvent or dispersion medium, the applied substances impart modified service properties to the treated materials.
  • the surface sealing element according to the invention for building has a textile layer which is impregnated over its entire surface with a non-tacky bonding agent.
  • a textile fabric is impregnated with an impregnating agent which contains a non-sticky adhesion promoter in the form of a solution, emulsion or dispersion.
  • the impregnating agent penetrates the fabric completely, penetrating into all pores, channels and openings of the textile. After evaporation or drying of the solvent or dispersion medium, the non-tacky adhesion promoter remains in the textile fabric or on all surfaces of the textile fabric.
  • a “primer” is generally understood to mean a substance which, by virtue of its properties, makes it possible to combine two materials which, owing to their chemical composition, can only be joined together very poorly by adhesives or which under poor environmental conditions are poorly bonded to one another can be connected. Bonding agents create a bond between the material and the adhesive in poorly bondable materials or surfaces or they improve the adhesion, if there are special requirements, such. As high wet / wet strength or temperature loads. Adhesion promoters are therefore used when different materials have to be glued together, which can not be connected to each other directly by an adhesive, or if a particular adhesive is to be used because of its special properties, but does not adhere well enough on one of the two adhesive partners.
  • the textile layer can be made thinner and thus less expensive. This too is due to the fact that no damage to the textile layer due to bonding occur on the construction site.
  • the adhesion promoter also increases the surface area of the fibers of the textile layer, as a result of which more adhesive surface area is available to the in-situ concrete, which at the same time improves the adhesion between fibers and concrete and thus between the area sealing element and concrete.
  • the foundednabêtlement invention also shows very excellent properties in the sealing of structures against water and gas.
  • the flat carrier prevents the penetration of gas and / or water, so it is a substantially gas- and / or waterproof flat carrier.
  • the nonwovens used according to the invention as a textile layer are available at favorable prices, have the required flexibility and provide a large specific surface area at which the adhesion promoter can adhere. Due to the very small perforations present in nonwovens, the impregnating agent can pass through and, after drying, is available as adhesion promoter on the surface facing away from the flat support for connection to the in-situ concrete. Since the textile layer is impregnated over its entire area with the non-tacky adhesion promoter, adhesion promoter is available over the entire surface of the surface sealing element, which bonds with the fresh concrete when casting the in-situ concrete.
