Definitions
- the invention relates to a flame-retardant carrier insert, which is in particular as a carrier insert for the production of roofing membranes, roofing underlays or suitable as a tarpaulin.
- Sufficient mechanical stability is required on the one hand, such as good perforation strength and good tensile strength, for example to the mechanical loads during further processing, such as bituminization or Embarrassed to withstand and on the other hand will have high resistance to thermal stress, for example when bituminizing or against radiating Warmth and resistance to wildfire are required.
- the present invention relates to a flame-retardant carrier insert at least one textile fabric and at least one powdered flame retardant material, optionally characterized in that the flame retardant material with or without additive by means of a meltable polymer, the adhesive temperature of which is below the softening temperature at least of the supporting fibers of the textile fabric and by means Exposure to heat and / or pressure up to the adhesive temperature of the meltable polymer on the Top of the fabric is attached.
- textile fabric is in the context of this description in to understand its broadest meaning. It can be all structures act from fibers, in particular from synthesized polymers, according to a surface-forming technology have been produced. Examples of such Structures are fabrics, knitted fabrics and preferably scrims, knitted fabrics and nonwovens.
- spunbonded fabrics which are produced by randomly depositing freshly melt-spun filaments are preferred. They consist of continuous synthetic fibers made of melt-spinnable polymer materials.
- Suitable polymer materials are, for example, polyamides, such as, for example, polyhexamethylene diadiparhide, poly-caprolactam, aromatic or partially aromatic polyamides (“aramids”), partially aromatic or fully aromatic polyesters, polyphenylene sulfide (PPS), polymers with ether and keto groups, such as, for example, polyether ketones (PEK ) and polyether ether ketone (PEEK), or polybenzimidazoles.
- PEK polyether ketones
- PEEK polyether ether ketone
- the spunbonded fabrics preferably consist of melt-spinnable polyesters.
- polyester material consist predominantly of building blocks which are derived from aromatic dicarboxylic acids and from aliphatic diols.
- Common aromatic dicarboxylic acid building blocks are the divalent residues of benzenedicarboxylic acids, especially terephthalic acid and isophthalic acid;
- Common diols have 2 to 4 carbon atoms, with the ethylene glycol being particularly suitable.
- Composites according to the invention are particularly advantageous, the nonwovens of which 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 specifically influence the physical and chemical properties of the filaments produced.
- dicarboxylic acid units are residues of isophthalic acid or of aliphatic dicarboxylic acid such as, for example, glutaric acid, adipic acid, sebacic acid;
- diol residues with a modifying action are those of longer-chain diols, for example of propanediol or butanedio, of di- or triethylene glycol or, if present in small amounts, of polyglycol with a molecular weight of approximately 500 to 2000.
- Polyesters are particularly preferred which contain at least 95 mol% Contain polyethylene terephthalate, especially those from unmodified Polyethylene terephthalate.
- the polyesters contained in the nonwovens usually have a Molecular weight corresponding to an intrinsic viscosity (IV) of 0.5 to 1.4 (dl / g), measured on solutions in dichloroacetic acid at 25 ° C.
- the textile fabrics made of fibers made of synthetic polymers for producing the carrier insert according to the invention have customary weights per unit area of 20 to 2000 g / m 2 , preferably 50 to 400 g / m 2 .
- the nonwovens are mechanically, for example, by Needling and / or chemically, for example, by melt binders are preferably introduced in fiber form, solidified.
- the textile Sheets made of fibers made of synthetic polymers also be melt-bond-bonded nonwoven, which carrier and binder fibers contains.
- the carrier and binding fibers can be any derive thermoplastic thread-forming polymers accordingly Requirement profile of the user.
- the proportion of the two types of fibers to each other can be chosen within wide limits, taking care is that the proportion of binding fibers is chosen so high that the nonwoven by gluing the carrier fibers with the binding fibers one for the desired one Application receives sufficient strength.
- the proportion of the from the binding fiber originating binder in the nonwoven is usually less than 50 wt .-%, based on the weight of the nonwoven fabric.
- Modified polyesters with a melting point which is lowered by 10 to 50 ° C., preferably 30 to 50 ° C., compared to the nonwoven raw material, are particularly suitable as melt binders.
- a binder are polypropylene, polybutylene terephthalate or by condensing longer-chain diols and / or polyethylene terephthalate modified by isophthalic acid or aliphatic dicarboxylic acids.
- the melt binders are preferably introduced into the nonwovens in the form of fibers, in particular in such a way that at least one surface - as a rule the surface to be equipped with the flame and / or fire protection materials - consists almost entirely of binding fibers, as is described in EP-A-0530769 describes.
- the individual fiber titers of the carrier and binding fibers are usually 1 to 16 dtex., Preferably 2 to 6 dtex.
- the nonwovens can be mechanical Solidification by needling and / or by means of fluid jets if necessary with the help of a chemical binder, for example based on a polyacrylate be solidified.
- Carrier inserts which are a combination of have preferred features.
- the filaments or staple fibers that make up the nonwovens can be one have practically round cross-section or have other shapes, such as dumbbell, kidney-shaped, triangular, tri or multilobal cross-sections. It hollow fibers can also be used. Furthermore, the binding fiber can also be in the form use of bicomponent or multicomponent fibers.
- the filaments forming the spunbonded nonwoven can be modified by conventional additives be, for example, by antistatic agents such as carbon black.
- the flame or fire protection material is preferably applied in an amount of 10 to 120 g / m 2 , particularly preferably in an amount of 20 to 80 g / m 2, to the top of the textile fabric made of fibers made of synthetic polymers, the application of the flame - or fire protection material before, at the same time or after the application of the meltable polymer, which acts as an adhesive, can take place.
- Flame or fire protection materials which are activated only above the usual temperatures of 180 ° C for bituminizing are particularly preferred.
- the additives used are preferably herbicides and / or fungicides which permanently prevent plant roots from penetrating the carrier insert. These additives are added in an amount determined by the subsequent use, usually between 0.0005 and 1 g / m 2 . Activated carbon is also possible as a further additive, so that the carrier insert according to the invention can also be used as a filter material.
- the meltable polymer has an adhesive temperature that is below the Softening temperature of at least the supporting fibers of the textile Fabric lies. If the fabric is made of fibers synthetic polymers is a melt-bond-bonded nonwoven, the Softening temperatures of the meltable polymer and the binding fibers of the melt-bond-bonded nonwoven also 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.

Description
Sie bestehen aus Endlos-Synthesefasern aus schmelzspinnbaren Polymermatierialien. Geeignete Polymermaterialien sind beispielsweise Polyamide, wie z.B. Polyhexamethylen-diadiparhid, Poly-caprolactam, aromatische oder teilaromatische Polyamide ("Aramide"), teilaromatische oder vollaromatische Polyester, Polyphenylensulfid (PPS), Polymere mit Ether- und Keto-gruppen, wie z.B. Polyetherketone (PEK) und Polyetheretherketon (PEEK), oder Polybenzimidazole.
Als Polyestermaterial kommen im Prinzip alle zur Faserherstellung geeigneten bekannten Typen in Betracht. Derartige Polyester bestehen überwiegend aus Bausteinen, die sich von aromatischen Dicarbonsäuren und von aliphatischen Diolen ableiten. Gängige aromatische Dicarbonsäurebausteine sind die zweiwertigen Reste von Benzoldicarbonsäuren, insbesondere der Terephthalsäure und der Isophthalsäure; gängige Diole haben 2 bis 4 C-Atome, wobei das Ethylenglycol besonders geeignet ist. Besonders vorteilhaft sind erfindungsgemäße Verbundstoffe, deren Vliese aus einem Polyestermaterial bestehen, das zu mindestens 85 mol% aus Polyethylenterephthalat besteht. Die restlichen 15 mol% bauen sich dann aus Dicarbonsäureeinheiten und Glycoleinheiten auf, die als sogenannte Modifizierungsmittel wirken und die es dem Fachmann gestatten, die physikalischen und chemischen Eigenschaften der hergestellten Filamente gezielt zu beeinflussen. Beispiele für solche Dicarbonsäureeinheiten sind Reste der Isophthalsäure oder von aliphatischen Dicarbonsäure wie z.B. Glutarsäure, Adipinsäure, Sebazinsäure; Beispiele für modifizierend wirkende Diolreste sind solche von längerkettigen Diolen, z.B. von Propandiol oder Butandio, von Di- oder Triethylenglycol oder, sofern in geringer Menge vorhanden, von Polyglycol mit einem Molgewicht von ca. 500 bis 2000.
Die Schmelzbinder werden vorzugsweise in Faserform in die Vliese eingebracht, insbesondere in einer solchen Weise, daß mindenstens eine - in der Regel die mit dem Flamm- und/oder Brandschutzmaterialien auszurüstende - Oberfläche nahezu vollständig aus Bindefasern besteht, wie dies die EP-A-0530769 beschreibt.
Die Einzelfasertiter der Träger- und der Bindefasern betragen üblicherweise 1 bis 16 dtex., vorzugsweise 2 bis 6 dtex.
Anschließend wird das mit dem Flammschutzmaterial und, gegebenenfalls Additiv und dem schmelzbaren Polymer beladene textile Flächengebilde aus Fasern aus synthetischen Polymeren mittels Wärmeeinwirkung und/oder Druck bis zur Klebetemperatur des schmelzbaren Polymeren behandelt, so daß das Flammschutzmaterial und, gegebenenfalls das Additiv auf der Oberseite des textilen Flächengebildes aus Fasern aus synthetischen Polymeren anhaftet.
Bevorzugt werden die Verstärkungsschichten in Form eines Gewebe oder Geleges angeordnet, wobei die Fadendichte zwischen 0,1 und 10 Fäden pro cm beträgt.
Es ist gleichermaßen bevorzugt, das erfindungsgemäße Verfahren mit dem Flächenbildungsprozess zu kombinieren oder das Verfahren nach dem Flächenbildungsprozess zu unterbrechen.
