Description
Die Erfindung betrifft eine Schlauchleitung, insbesondere für Trinkwasseranwendungen, mit
- - einer polymeren elastischen Schicht, die ein thermoplastisches Elastomer (TPE) mit einer thermoplastischen Komponente (TK) und einer elastomeren Komponente (EK) enthält,
- - einer die elastische Schicht umgebenden Armierungsschicht und
- - einer die Armierungsschicht umgebenden äußeren Schicht aus polymerem Material.
- - a polymeric elastic layer containing a thermoplastic elastomer (TPE) with a thermoplastic component (TK) and an elastomeric component (EK),
- - A reinforcement layer surrounding the elastic layer and
- - An outer layer of polymeric material surrounding the reinforcement layer.
Schläuche für Trinkwasser wurden früher aus Weich-PVC oder Gummimaterialien hergestellt, um die gewünschte Flexibilität sicherstellen zu können. Seit geraumer Zeit kommen jedoch spezielle Polyolefin-Materialien bzw. spezielle thermoplastische Elastomere (TPE) zum Einsatz, z.B. thermoplastische Elastomere auf Styrolbasis (TPE-S). Es können weitere Rezepturkomponenten vorgesehen sein, sowie ggf. Füllstoffe und Stabilisatoren, um die Anforderungen der von der Deutschen Trinkwasserverordnung als „allgemein anerkannte Regeln der Technik“ abzuleitenden Hygienestandards „technische Regel Arbeitsblatt W 270“ (DIN EN 16421 - Verfahren 2) des DVGW, sowie „Leitlinie zur hygienischen Beurteilung von anorganischen Materialien im Kontakt mit Trinkwasser (KTW-Leitlinie)“ des Deutschen Umweltbundesamtes zu erfüllen.Hoses for drinking water used to be made of soft PVC or rubber materials in order to be able to ensure the desired flexibility. For some time now, however, special polyolefin materials or special thermoplastic elastomers (TPE) have been used, e.g. thermoplastic elastomers based on styrene (TPE-S). Further formulation components can be provided, as well as fillers and stabilizers, if necessary, in order to meet the requirements of the hygiene standards "technical rule worksheet W 270" (DIN EN 16421 - method 2) of the DVGW, which are to be derived from the German Drinking Water Ordinance as "generally recognized rules of technology", as well as "Guideline for the hygienic assessment of inorganic materials in contact with drinking water (KTW guideline)" of the German Federal Environment Agency.
Die
Die
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Schlauchleitung mit den eingangs beschriebenen Merkmalen anzugeben, welche sich durch eine hohe chemische Beständigkeit auszeichnet, eine geringe Verschmutzungsneigung an ihrer inneren, mit dem zu transportierenden Fluid beaufschlagten Oberfläche aufweist und die sich darüber hinaus kostengünstig herstellen lässt.Against this background, the invention is based on the object of specifying a hose line with the features described above, which is characterized by high chemical resistance, has a low tendency to soiling on its inner surface exposed to the fluid to be transported and which can also be produced inexpensively leaves.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass an der Innenseite der elastischen Schicht eine vergleichsweise harte polymere Innenschicht vorgesehen ist, deren innere Oberfläche einen freien Querschnitt für den Transport eines zu führenden Fluids begrenzt, dass die Innenschicht eine Härte Shore A von mehr als 85, z.B. mindestens 86 oder mindestens 87 aufweist, und dass die äußere Schicht aus mindestens zwei Teilschichten aufgebaut ist. Die Härte Shore A wird hierbei zweckmäßigerweise nach
Zweckmäßigerweise enthält die Innenschicht ein TPE und/oder ein Polyolefin (vorzugsweise ein Ethylen- oder Propylen-Homopolymer) und/oder ein Polyolefin-Copolymer (vorzugsweise ein Ethylen- oder Propylen-Copolymer) bzw. besteht daraus. Im Falle eines Polyolefin-Copolymers enthält dieses vorzugsweise Alpha-Olefine und/oder Vinylacetat-Comonomere und/oder Alkylacrylat-Comonomere.The inner layer expediently contains or consists of a TPE and / or a polyolefin (preferably an ethylene or propylene homopolymer) and / or a polyolefin copolymer (preferably an ethylene or propylene copolymer). In the case of a polyolefin copolymer, this preferably contains alpha-olefins and / or vinyl acetate comonomers and / or alkyl acrylate comonomers.
Vorzugsweise weist die Innenschicht eine Härte Shore A von mehr als 85 bis 90, z.B. 87 bis 90 auf. Zweckmäßigerweise ist die Härte Shore A der Innenschicht mindestens 3, vorzugsweise mindestens 5 höher als die Härte Shore A der elastischen Schicht. Wenn beispielsweise also die Härte Shore A der Innenschicht 86 beträgt, so weist in diesem Fall die elastische Schicht dann eine Härte Shore A von maximal 81 auf.The inner layer preferably has a Shore A hardness of more than 85 to 90, e.g. 87 to 90. The Shore A hardness of the inner layer is expediently at least 3, preferably at least 5 higher than the Shore A hardness of the elastic layer. If, for example, the hardness is Shore A of the inner layer 86, then in this case the elastic layer then has a hardness Shore A of a maximum of 81.
Die Innenschicht ist zweckmäßigerweise vergleichsweise dünn und weist z.B. eine Schichtdicke von 0,1 bis 0,5 mm, vorzugsweise 0,2 bis 0,4 mm, auf. Die Armierungsschicht kann, vorzugsweise diagonal gewickelte und/oder geflochtene, Filamente aufweisen.The inner layer is expediently comparatively thin and has, for example, a layer thickness of 0.1 to 0.5 mm, preferably 0.2 to 0.4 mm. The reinforcement layer can have filaments, preferably diagonally wound and / or braided.
Gemäß einer bevorzugten Ausführungsform der Erfindung beträgt der Gewichtsanteil der elastischen Komponente (EK) in der elastischen Schicht
Die Innenschicht kann je nach Bedarf zusätzlich Stabilisatoren, z.B. chemische Stabilisatoren und/oder Thermostabilisatoren und/oder UV-Stabilisatoren enthalten.The inner layer can additionally contain stabilizers, e.g. chemical stabilizers and / or thermal stabilizers and / or UV stabilizers, as required.
Die polymeren Schichten werden zweckmäßigerweise mittels eines Polymerverarbeitungsverfahren, insbesondere mittels Extrusion hergestellt. Im Rahmen der Erfindung liegt hierbei insbesondere, dass die elastische Schicht und die Innenschicht coextrudiert sind.The polymeric layers are expediently produced by means of a polymer processing method, in particular by means of extrusion. In this context, the scope of the invention lies particularly in the fact that the elastic layer and the inner layer are coextruded.
Zweckmäßigerweise enthält mindestens eine der Teilschichten der äußeren Schicht ein TPE. Insbesondere können beide Teilschichten aus einem TPE bestehen.At least one of the sub-layers of the outer layer expediently contains a TPE. In particular, both sub-layers can consist of a TPE.
Im Rahmen der Erfindung liegt es ferner, dass mindestens eine der Teilschichten Farbpigmente enthält und/oder einen Farbauftrag aufweist und/oder einen Transmissionsgrad > 0, vorzugsweise > 10 %, insbesondere > 20 % aufweist. Durch einen Transmissionsgrad > 0 zumindest in Bezug auf die äußerste Teilschicht kann ein optischer Tiefeneffekt bei der erfindungsgemäßen Schlauchleitung erzielt werden. Der Transmissionsgrad gibt an, wie groß der Anteil der durchgelassenen Lichtwellen durch die entsprechende Teilschicht im Verhältnis zu den auf die Teilschicht auftreffenden Lichtwellen ist.It is also within the scope of the invention that at least one of the partial layers contains color pigments and / or has an application of color and / or has a transmittance> 0, preferably> 10%, in particular> 20%. With a degree of transmission> 0, at least with respect to the outermost partial layer, an optical depth effect can be achieved in the hose line according to the invention. The degree of transmission indicates how large the proportion of the light waves transmitted through the corresponding sublayer is in relation to the light waves incident on the sublayer.
