Definitions

  • the invention relates to a flame resistant shingle, as well as roofs and roofs made therefrom.
  • Flame retardant shingles have to meet a variety of requirements. This is achieved by a multi-layered construction of the shingle.
  • Known flame retardant shingles which substantially meet the requirements, have a laminate-like construction of a plurality of discrete specialty bitumen and glass fiber nonwoven layers.
  • flame-retardant shingles are known, which contain only a heavy glass-fleece insert, so that the multilayer structure described above is simplified.
  • the above-mentioned heavy glass nonwoven inserts usually have a basis weight of at least 100 g / m 2 .
  • the above-described laminate-like construction or the heavy glass fleece insert give the shingle, on the one hand, sufficient mechanical stability and, on the other hand, high resistance to flying blasts and radiant heat.
  • the flame-retardant shingles must have a high dimensional stability, so that they have no deformations that would result in Dachundenburgenburgen even after prolonged use as intended.
  • the hitherto known flame-retardant shingles either show a laminate-type construction of discrete special bitumen and glass fiber nonwoven layers, which can only be realized in a relatively expensive manner, or they contain heavy glass fleece inserts which are relatively expensive.
  • Another disadvantage is that bitumen adhesion to glass fiber webs is problematic. Furthermore, due to the different physical properties of the individual layers, delamination can not be ruled out.
  • it is desirable that the shingles have a high Nagelausr dichfesttechnik, since the shingles are usually attached by nails on the roof construction.
  • EP-A-0 745 718 and EP-A-0 634 515 describe roofing membranes and the EP-A-0573363 Shingle, which are partially fire retardant equipped.

Examples of such structures are woven, knitted fabrics and preferably scrims, knitted fabrics and nonwovens.
  • Wool, cotton, flax, sisal, coconut, and / or cellulose fibers are understood in particular as natural fibers.
  • fibers are both fibers of finite length, so-called staple fibers, as well as endless fibers, so-called filaments understood.

Particularly advantageous are composites according to the invention whose nonwovens consist of a polyester material which consists of at least 85 mol% of polyethylene terephthalate.
  • dicarboxylic acid units and glycol units which act as so-called modifying agents and which allow the person skilled in the art to influence the physical and chemical properties of the filaments produced in a targeted manner.

  • the melt binders are preferably introduced into the nonwovens in fibrous form, in particular in such a way that at least one - usually to be equipped with the flame and / or fire protection materials - surface consists almost entirely of binder fibers, as the EP-A-0530769 describes.
  • the individual fiber titers of the carrier and binder fibers are usually 1 to 16 dtex, preferably 2 to 6 dtex.
  • the nonwovens may be finally solidified after mechanical consolidation by needling and / or by means of fluid jets optionally with the aid of a chemical binder, for example based on a polyacrylate.
  • Particularly preferred are also those textile fabrics which have a combination of preferred features.
  • the filaments or staple fibers constituting the nonwovens may have a practically round cross section or may have other shapes, such as dumbbell, kidney, triangular or tri or multilobal cross sections.
  • the binder fiber can also be used in the form of Bioder multicomponent fibers, it must be ensured that the binder is available for solidification. In the case of core / sheath bicomponent fibers this means that the sheath component is essentially built up from the melt binder.
  • the spunbonded filaments can be modified by conventional additives, for example by antistatic agents such as carbon black and / or water repellents.

  • the fabric contains a proportion of fibers which can act as melt binders, it is of particular advantage if these are used as in EP-A-0,530,769 are arranged described in detail. These adhesive fibers may also be present as bicomponent or heterofil fiber.
  • the flame retardant can also be incorporated into the bitumen and applied together with this.
  • this has the disadvantage that only a small amount of the flame retardant can be active and thus the consumption of flame retardant is much higher.

It is essential, however, that in this variant, the flame retardant in an amount of up to 20%, in particular 5 to 10%, based on the weight of the finished shingle, is introduced.
  • the flame retardant can be applied together with the optionally liquefied binder in the form of a dispersion or suspension.
  • the amount of binder required to fix the flame retardant depends essentially on the nature of the binder. If the binder is a fusible polymeric binder, it is applied to the textile fabric in an amount of from 5 to 120 g / m 2 , more preferably in an amount of from 10 to 40 g / m 2 , at least on one side.
  • the loaded with the flame retardant material and the binder fabric is treated by means of heat and / or pressure, so that the flame retardant material adheres to the top of the textile fabric.

  • the shape of the shingles is not limited, but classic forms such as beaver tail shingles are preferred for aesthetic reasons.
  • the punched shingle can be present as a single shingles or as Schindelbahn. In the latter case, it is due to the selection of the punch to a strip of several coexisting shingles, which are still connected to each other. Shingle shapes of this type are described in detail, for example, in product data sheets for ICOPAL shingles or ICOPAL shingles exclusively (Icopal-Siplast GmbH, Germany).

Furthermore, the processability can be improved if a fusible protective film is attached to the underside of the finished shingle. This prevents sticking together of the shingles during storage and transport and can be removed by flame if necessary. This is necessary in particular along all joints and connections, since a shingle adhesive is usually applied here.
