Description
Die Erfindung betrifft ein Kunststoffrohr insbesondere für Fußbodenheizungen und/oder die Heizkörperanbindung.The invention relates to a plastic pipe, in particular for underfloor heating and/or radiator connections.
Ein Mehrschichtrohr, wie es Gegenstand der Erfindung ist, ist z. B. aus DE 296 06 533 Ul bekannt. Dieses bekannte Rohr weist ein Basisrohr, eine Sauerstoffdiffusionssperrschicht und ein Außenrohr als Schutz für die Sauerstoffdiffusionssperrschicht auf. Zwischen dem Basisrohr und der Sauerstoffsperrschicht sowie zwischen dieser und dem Außenrohr ist jeweils eine Schicht aus Haftvermittler angeordnet.A multilayer pipe, as is the subject of the invention, is known, for example, from DE 296 06 533 Ul. This known pipe has a base pipe, an oxygen diffusion barrier layer and an outer pipe as protection for the oxygen diffusion barrier layer. A layer of adhesion promoter is arranged between the base pipe and the oxygen barrier layer and between this and the outer pipe.
Das bekannte Fünfschichtrohr hat sich in der Praxis grundsätzlich bewährt, ist jedoch relativ biegesteif.The well-known five-layer pipe has basically proven itself in practice, but is relatively rigid.
Der Erfindung liegt die Aufgabe zu Grunde, ein Mehrschicht-Kunststoffrohr zu schaffen, das trotz seines Mehrschichtaufbaus noch relativ flexibel ist.The invention is based on the object of creating a multi-layer plastic pipe which, despite its multi-layer structure, is still relatively flexible.
Zur Lösung dieser Aufgabe wird mit der Erfindung ein Mehrschicht-Kunststoffrohr vorgeschlagen, das zumindest versehen ist mitTo solve this problem, the invention proposes a multilayer plastic pipe which is provided with at least
- einem Basisrohr,- a base tube,
einer auf das Basisrohr aufgebrachten ersten Haftvermittlerschicht,
einer auf der ersten Haftvermittlerschicht aufgebrachten Diffusionssperrschicht,
einer zweiten Haftvermittlerschicht auf der Diffusionssperrschicht unda first adhesion promoter layer applied to the base tube,
a diffusion barrier layer applied to the first adhesion promoter layer,
a second adhesion promoter layer on the diffusion barrier layer and
- einem Außenrohr, das sich auf der zweiten Haftvermittlerschicht befindet, wobei
das Basisrohr und das Außenrohr aus einem MD-PE Material bestehen.- an outer tube located on the second bonding layer, wherein
the base pipe and the outer pipe are made of an MD-PE material.
Nach der Erfindung handelt es sich bei dem Material für das Basis- oder Innenrohr und das Außenrohr um MD-PE, also um ein PE mit einer Dichte im Bereich von etwa 0,932 bis 0,939 g/cm3. Die Haftvermittlerschichten basieren vorzugsweise ebenfalls auf einem PE-Material mit zusätzlichen Polymeren bzw. Copolymeren. Durch die Verwendung von MD-PE für das Basis- und das Außenrohr wird dem erfindungsgemäßen mindestens fünf Kunststoffschichten aufweisenden Rohr eine erhöhte Flexibilität verliehen.According to the invention, the material for the base or inner pipe and the outer pipe is MD-PE, i.e. a PE with a density in the range of about 0.932 to 0.939 g/cm 3 . The adhesion promoter layers are preferably also based on a PE material with additional polymers or copolymers. By using MD-PE for the base and outer pipe, the pipe according to the invention, which has at least five plastic layers, is given increased flexibility.
Vorzugsweise wird als Material für die Sauerstoffsperrschicht EVOH eingesetzt. Zweckmäßigerweise ist das gesamte Rohr, zumindest jedoch das Basisrohr vernetzt, und zwar zumindest teilweise, und zwar zu etwa 50% bis 60%. Die Vernetzung erfolgt dabei vorteilhafterweise mittels Elektronenstrahlen.EVOH is preferably used as the material for the oxygen barrier layer. The entire pipe, or at least the base pipe, is expediently cross-linked, at least partially, namely by about 50% to 60%. Cross-linking is advantageously carried out using electron beams.
Nachfolgend wird anhand der Zeichnung ein Ausführungsbeispiel der Erfindung näher erläutert. In der Zeichnung ist ein Querschnitt durch ein Fünf-Schicht-Kunststoffrohr mit in der neutralen Zone angeordneter Sauerstoffdiffusions-Sperrschicht dargestellt, was zwar vorteilhaft, für die Erfindung aber nicht zwingend notwendig ist.An embodiment of the invention is explained in more detail below with reference to the drawing. The drawing shows a cross section through a five-layer plastic pipe with an oxygen diffusion barrier layer arranged in the neutral zone, which is advantageous but not absolutely necessary for the invention.
Es sei vorausgeschickt, dass die Schichtdicken des in der Zeichnung im Querschnitt gezeigten Rohres weder relativ zueinander noch absolut maßstabsgerecht gezeichnet sind.It should be noted that the layer thicknesses of the pipe shown in cross-section in the drawing are neither relative to each other nor absolutely to scale.
Die Zeichnung zeigt im Querschnitt ein Kunststoffrohr 30 mit einem bezüglich der Anordnung der Sperrschicht symmetrischen Wandaufbau. Auf die Innenschicht (Basisrohr 32) am MD-PE ist eine Haftvermittlerschicht 34 aufgebracht, die das Basisrohr 32 mit einer Sauerstoffdiffusionssperrschicht 36 aus EVOH verbindet. Außen auf der Sperrschicht 36 befindet sich eine weitere Haftvermittlerschicht 38. Diese Schicht 38 ist von einer Außenschicht (Außenrohr 40) aus MD-PE umgeben, die über die Haftvermittlerschicht 38 mit der Sperr-The drawing shows a cross-section of a plastic pipe 30 with a wall structure that is symmetrical with respect to the arrangement of the barrier layer. An adhesion promoter layer 34 is applied to the inner layer (base pipe 32) on the MD-PE, which connects the base pipe 32 to an oxygen diffusion barrier layer 36 made of EVOH. On the outside of the barrier layer 36 there is another adhesion promoter layer 38. This layer 38 is surrounded by an outer layer (outer pipe 40) made of MD-PE, which is connected to the barrier layer 36 via the adhesion promoter layer 38.
schicht 36 verbunden ist Die beiden Schichten 38 und 40 bilden eine mehrlagige Schutzschicht 42 zum Schutz der Sperrschicht 36.layer 36 is connected. The two layers 38 and 40 form a multi-layer protective layer 42 to protect the barrier layer 36.
Die Summe der Dicken d32 und d34 von Basisrohr 32 und Haftvermittlerschicht 34 ist im wesentlichen gleich der Summe der Dicken d38 und d40 von Haftvermittlerschicht 38 und Außenschicht 40. Die Teildicken der Wandung des Kunststoffrohres 30 zu beiden Seiten der Sperrschicht 36 sind also im wesentlichen gleich.The sum of the thicknesses d 32 and d 34 of the base pipe 32 and the adhesion promoter layer 34 is essentially equal to the sum of the thicknesses d 38 and d 40 of the adhesion promoter layer 38 and the outer layer 40. The partial thicknesses of the wall of the plastic pipe 30 on both sides of the barrier layer 36 are therefore essentially equal.
