Abstract

The cool water tube (1) comprises an internal layer (9) made of a first polymer material that is completely free from fibers, and an external layer (10) made of second polymer materials that are mixed with glass fibers.

Description

Die Erfindung betrifft ein Rohr, insbesondere ein Kühlwasserrohr, aus einem polymeren Werkstoff.The The invention relates to a pipe, in particular a cooling water pipe, made of a polymer material.

Ein Rohr der oben genannten Art wird insbesondere im Fahrzeugbau, in der Sanitärtechnik und auf dem Bausektor eingesetzt. Dabei wird bislang nur eine Materialkomponente, nämlich glasfasergefülltes Polyamid, insbesondere PA6.6, verwendet ( WO 03/106558 A1 ). Die Herstellung erfolgt dabei nach der Gasinjektionstechnik (GIT), Projektilinjektionstechnik (PIT) und Wasserinjektionstechnik (WIT).A tube of the type mentioned above is used in particular in vehicle construction, in sanitary engineering and in the construction sector. Only one material component, namely glass fiber-filled polyamide, in particular PA6.6, has hitherto been used ( WO 03/106558 A1 ). They are manufactured using gas injection technology (GIT), projectile injection technology (PIT) and water injection technology (WIT).

Das bislang eingesetzte Material ist nicht vollständig hydrolysebeständig. Hinzu kommt, dass die Innenoberfläche des Rohres rau ausgebildet ist, da die Glasfasern hervorstehen. Dies führt zum Auswaschen der Glasfasern im Einsatzfall und zu erhöhtem Druckverlust bei der Durchströmung von Wasser, beispielsweise von Kühlwasser im Fahrzeug.The previously used material is not completely hydrolysis resistant. In addition, the inner surface of the tube is made rough is because the glass fibers protrude. This leads to washing out the glass fibers in the application and to increased pressure loss in the flow of water, such as cooling water in the vehicle.

Zur Lösung dieser Problematik zeichnet sich das neue Rohr, insbesondere Kühlwasserrohr, gemäß Kennzeichen des Patentanspruches 1 durch wenigstens folgenden Schichtenaufbau aus:

  • – eine Innenschicht aus einem ersten polymeren Werkstoff A, der frei von Glasfasern ist; sowie
  • – eine Außenschicht aus einem zweiten polymeren Werkstoff B, dem Fasern beigemischt sind.
To solve this problem, the new pipe, in particular cooling water pipe, characterized according to the characterizing part of claim 1 by at least the following layer structure:
  • An inner layer of a first polymeric material A which is free of glass fibers; such as
  • - An outer layer of a second polymeric material B, the fibers are admixed.

Zweckmäßige Ausgestaltungen des neuen Rohres werden in den Patentansprüchen 2 bis 8 genannt.expedient Embodiments of the new tube are in the claims 2 to 8 called.

Die Erfindung wird nun anhand eines Ausführungsbeispieles unter Bezugnahme auf schematische Zeichnungen erläutert. Es zeigen:The Invention will now be based on an embodiment below Referring to schematic drawings explained. Show it:

1 ein Kühlwasserrohr für den Fahrzeugbau; 1 a cooling water pipe for vehicle construction;

2 einen Querschnitt durch ein Kühlwasserrohr mit einer Innen- und Außenschicht. 2 a cross section through a cooling water pipe with an inner and outer layer.

1 zeigt ein Kühlwasserrohr 1 aus einem polymeren Werkstoff mit einem geraden Rohrbereich 2, einem gekrümmten Rohrbereich 3, einem Rohrabzweig 4, drei Anschlüssen 5, 6 und 7 sowie einer Halterung 8. Auf die drei Anschlüsse werden beispielsweise Schläuche aus einem elastomeren Werkstoff aufgezogen und verklemmt, beispielsweise nach der Patentschrift EP 1 208 322 B1 . 1 shows a cooling water pipe 1 made of a polymer material with a straight tube area 2 , a curved pipe section 3 a pipe branch 4 , three connections 5 . 6 and 7 as well as a holder 8th , For example, hoses made of an elastomeric material are mounted on the three connections and clamped, for example according to the patent EP 1 208 322 B1 ,

Nach 2 besteht das Kühlwasserrohr 1 ausschließlich aus einer Innenschicht 9 und Außenschicht 10, und zwar unter folgenden Werkstoffkriterien:To 2 is the cooling water pipe 1 exclusively from an inner layer 9 and outer layer 10 , under the following material criteria:

Innenschichtinner layer

Die Innenschicht 9 besteht aus einem ersten polymeren Werkstoff A, der frei von Glasfasern ist. Zweckmäßigerweise ist dieser Werkstoff vollständig frei von Fasern. Eingesetzt wird insbesondere ein Polyolefin, insbesondere wiederum ein Polypropylen (PP). Die Innenschicht ist nun hydrolysebeständig, wobei sich zudem eine glatte Innenoberfläche realisieren lässt.The inner layer 9 consists of a first polymeric material A, which is free of glass fibers. Conveniently, this material is completely free of fibers. In particular, a polyolefin, in particular a polypropylene (PP), is used. The inner layer is now resistant to hydrolysis, whereby in addition a smooth inner surface can be realized.

Außenschichtouter layer

Die Außenschicht 10 besteht aus einem zweiten polymeren Werkstoff B, dem Fasern beigemischt sind, vorzugsweise Glasfasern. Eingesetzt wird insbesondere ein Polyamid (PA), das insbesondere wiederum ausgewählt ist aus folgenden Gruppen, nämlich PA6, PA6.6, PA11, PA12, PA6.10, PA6.12 oder einem Copolyamid.The outer layer 10 consists of a second polymeric material B, the fibers are mixed, preferably glass fibers. In particular, a polyamide (PA) is used which, in turn, is selected from the following groups, namely PA6, PA6.6, PA11, PA12, PA6.10, PA6.12 or a copolyamide.
