Definitions

  • the present invention relates to a flame retardant carrier insert, especially for Bitumen membranes, which provide improved adhesion of the bitumen on the liner guaranteed.
  • a flame-retardant carrier insert is known, at least a textile fabric and at least one powdered flame retardant material and / or a powdered additive, wherein the flame retardant material and / or additive by means of a fusible polymer is attached, whose adhesive temperature below the Softening temperature of at least the load-bearing fibers of the textile fabric is.
  • bitumen is then later on the already covered with the flame retardant side applied to the textile fabric, so that in the resulting bituminous membranes, the Flame retardant layer between the bitumen and the textile fabric is arranged. This can lead to a reduction in the adhesion of the later applied bitumen layer come because these are not so good on the flame retardant sticks like directly on the textile fabric.
  • the object of the present invention is therefore to provide a flame retardant
  • a carrier insert which is a textile fabric with applied Flame retardant layer comprises and on which a later applied bituminous layer with adhering to the same or almost the same strength as on the textile fabric alone.
  • the object is achieved in that the fabric has a coverage between 30% and 90% of its surface area in the case of a medium, ie over the entire surface of the textile averaged order of flame retardants in the range of 20 to 100 g / m 2 , ie in that the flame retardant is applied only to partial areas of the surface, while the remaining partial areas of the surface of the textile fabric remain completely uncovered by the flame retardant.
  • textile fabric is to be understood in its broadest meaning. It can consequently all structures made of fibers, in particular of synthetic polymers, which have been produced by a surface-forming technique. Examples of such structures are woven, knitted fabrics and preferably scrims, knitted fabrics and nonwovens.
  • spunbonds preferred, which are produced by a Wirrablage freshly melt spun filaments. They consist of continuous synthetic fibers of fusible polymer materials.
  • suitable Polymeric materials are, for example, polyamides, e.g. Polyhexamethylene diadipamide, Poly-caprolactam, aromatic or partially aromatic polyamides ("aramids"), partially aromatic or wholly aromatic polyesters, polyphenylene sulfide (PPS), polymers with ether and Keto groups, e.g. Polyether ketones (PEK) and polyetheretherketone (PEEK), or Polybenzimidazoles.
  • the flame or fire protection material is applied in an amount of 20 to 100 g / m 2 on the top of the fabric of synthetic polymer fibers, wherein the application of the flame or fire protection material before, simultaneously or after the application of a fusible polymer, as Adhesive acts, can be done. Flame or fire protection materials which are activated only above the temperatures of 180 ° C. customary in bituminizing are particularly preferred.
  • the fusible polymer used as the adhesive has an adhesive temperature which is below the Softening temperature of at least the load-bearing fibers of the textile fabric is. If the fabric of synthetic polymer fibers a meltbond-strengthened nonwoven fabric, the softening temperatures of the fusible polymer and the binder fibers of the meltbinder-bonded nonwoven fabric as well be almost the same or even overlap.
  • the meltable polymer can be applied in the form of powders, granules, staple fibers, continuous fibers, film or as a textile fabric.
  • Suitable fusible polymers are thermoplastic polymers or resins.
  • Suitable thermoplastic polymers are polyolefins such as polypropylene, polyethylene, as well as polyamides and polybutylene terephthalate and modified polyethylene terephthalates - using aliphatic dicarboxylic acids or isophthalic acid.
  • the meltable polymer is applied in an amount of 5 to 120 g / m 2 , more preferably in an amount of 10 to 40 g / m 2, to the upper surface of the synthetic polymer fiber fabric.
  • the Duromers can condense.
  • Particularly preferred for the attachment of Flame retardant on the sheet are crosslinking resins such as e.g. Melamine-, Epoxy or phenolic resins or mixtures thereof.
  • adhesive temperature is meant the temperature at which the meltable polymer is the Base insert and the flame retardant and / or the additive wetted, so that a sufficient adhesion of the flame retardant and / or the additive on the carrier insert results and subsequent operations, such as winding or bituminizing, without detachment of the flame retardant and / or additive.
  • this is applied to the textile fabric Flame retardant a regular pattern.
  • Particularly preferred are as a pattern contiguous or completely separated polygons, e.g. Triangles, squares or diamonds.
  • the Flame retardants instead of an order in regular patterns also in the form of Be applied to company logos or lettering.
  • the flame retardant in the form of transverse, diagonal or arranged longitudinal strips are also in the form of transverse, diagonal or arranged longitudinal strips.
  • bitumen adhesion ensures that the flame retardant only parts of the surface covered by the textile area, totaling between 30% and 90%, while the remaining parts are uncovered and can provide increased bitumen adhesion.
  • this showed the bitumen adhesion on the textile fabric even then equal or almost equal to the bitumen adhesion on a with Flame retardant uncovered backing was when the fabric was 30% until 90% of its total surface was covered with flame retardant, being covered and uncovered portions preferably distributed over the entire surface regularly.
  • the partial covering of the surface according to the invention is preferably via the targeted Arrangement of the flame retardant in the form of a pattern achieved. Although that Flame retardant then no more contiguous surface areas covered, but instead the cover is interrupted by exposed surface areas, remains nevertheless adequate flame protection ensured.
  • Example 1 (Comparative Example )
  • the nonwoven fabric used was a needled and bonded with a chemical binder bonded filament nonwoven fabric made of polyester with a basis weight of 160 g / m 2 (trade name Trevira® Spunbond Type 033) intended as a support for Bitumendach- and geomembranes.
  • the infrared radiator was adjusted to a surface temperature of 150 ° C with a radiation pyrometer. After passing through the squeeze roller pair, the surface temperature was 35-45 ° C.
  • the coated carrier was on a conventional plant for the production of roofing Geomembranes processed with polymer modified bitumen. At the finished Dachund Geomembrane only a low bitumen adhesion could be determined.
  • Example 1 The experiment of Example 1 was repeated, except that the powder mixture made of expandable graphite and adhesive was spread in strips on the nonwoven fabric.
  • the coated strips had a width of 8 mm and uncoated graphite-free Strip a width of 4 mm.
  • the coated area was 67% of the total area.
  • the used powder was, as in Example 1, a mixture of an expandable graphite with a average particle size of 0.1 to 0.3 mm and the adhesive powder in a weight ratio of 1: 1.
  • the total area average of the mixture was 85 g / m 2 , ie 85 g was effectively distributed over 0.67 m 2 area, resulting in an application of 63 g / m 2 of flame retardant to the coated strips revealed. On the bitumen roofing membrane a satisfactory bitumen adhesion could be determined.
