Definitions

  • the present invention relates to a nonwoven fabric, which preferably consists of polyester filaments and is suitable for use in roofing membranes that are resistant to flying flames and radiant heat.
  • These roofing sheets are usually provided with a bitumen layer, but can also have a coating of elastomers or plastomers.
  • Such carriers for roofing membranes are known per se from German Patent 28 27 136. They consist of a nonwoven, e.g. made of polyester filaments and one punctiform e.g. metal foil fastened by needles, for example a folded aluminum foil. Such a metal foil is preserved as an undamaged layer in a local flying fire and thereby prevents the fire from spreading into the lower layers of a roof waterproofing.
  • the above-mentioned laminate made of a fleece and a metal foil is effective against flying fire and radiant heat, but it can only be produced with great effort.
  • German Offenlegungsschrift 26 55 038 describes a process for the production of flame-retardant bitumen corrugated sheets.
  • the raw cardboard used for this purpose is to be impregnated with an aqueous solution of a mixture of a wide variety of flame retardants. After the cardboard thus impregnated has been shaped and dried, it is then impregnated with bitumen.
  • the use of such a mixture in a nonwoven also does not lead to the desired success.
  • there are processing difficulties which include are based on the significantly lower absorbency and swelling capacity of the nonwoven used and on the substantially higher flexibility of the nonwoven as a reinforcing material.
  • nonwovens made of synthetic fibers and / or filaments meet the desired requirements if, according to the present invention, they are equipped with a flame retardant prior to coating, which is inert up to temperatures well above the melting point of the coating material, and higher Temperatures but forms a largely closed layer on the nonwoven.
  • the closed layer which forms should preferably have a foam-like character. If the nonwoven is coated with bitumen, this should be done according to the invention required fire protection agents are inert at least up to temperatures of about 220 ° C, preferably 250 t or even 300 ° C, but then form a largely closed layer at slightly higher temperatures.
  • these flame retardant finishes can be applied to the nonwoven directly during the formation of the nonwoven or simultaneously with binders or other finishing agents.
  • this equipment can be integrated into the normal nonwoven manufacturing process and requires no further process steps and no additional devices for its production.
  • the equipment can also be used according to known methods such as e.g. passing through an immersion bath, splashing or spraying e.g. in the form of aqueous dispersions, if appropriate, be applied immediately before the actual bitumen coating, provided that it is ensured that the dispersant is largely removed again before the actual coating.
  • a surface-covering, preferably foam-like layer should form at high temperatures in accordance with the invention, which cannot flow off through non-melting nonwoven layers, but, like the metal foil according to the prior art, spread the fire into the nonwoven layers and bitumen layers underneath as well as the others Roof structure prevented.
