Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von verstreckbaren Monofilen durch Extrusion einer ternären Formmasse auf Basis thermoplastischer Kunststoffe und hieraus durch Extrusion mit anschließender Verstreckung hergestellte Monofile.The invention relates to a process for the production of stretchable monofilaments by extrusion of a ternary molding compound based on thermoplastic materials and monofilaments produced therefrom by extrusion with subsequent stretching.
Wegen der vielseitigen Eigenschaften der linearen Polyarylen-oxide und -sulfide, insbesondere ihrer ausgezeichneten Hitzebeständigkeit, guten mechanischen Eigenschaften, hervorragenden Hydrolyse- und chemischen Beständigkeit, flammenhemmenden Eigenschaft, guten elektrischen Eigenschaften und geringen Wasseraufnahme ist auch ihr Einsatz in Gestalt von Monofilen gefordert.Because of the versatile properties of the linear polyarylene oxides and sulfides, in particular their excellent heat resistance, good mechanical properties, excellent hydrolysis and chemical resistance, flame retardant property, good electrical properties and low water absorption, their use in the form of monofilaments is also required.
Die Erfindung befaßt sich insbesondere mit der Herstellung von hochtemperaturfesten Monofilen auf Basis geeigneter thermoplastischer Kunststoffe, wie beispielsweise Polyphenylensulfid, das einen Kristallit-Schmelzpunkt von etwa 285°C aufweist, siehe auch Zeitschrift Kunststoffe, 77 (1987), S. 1023-1027. Wegen ihrer hohen Kristallinität neigen jedoch Fasern und Monofile von Polyarylensulfiden und -oxiden zur Brüchigkeit. Man hat daher bereits versucht, die Geschmeidigkeit und Verarbeitbarkeit von Polyphenylensulfid zum Herstellen von Monofilen durch Zugabe von Polyfluorcarbonen, insbesondere Polytetrafluorethylen zu verbessern, wie beispielsweise aus der EP-OS 0221 691 oder US-PS 4493 917 bekannt geworden. Es hat sich jedoch herausgestellt, daß die Verarbeitung der binären Mischungen von Polyarylensulfiden oder -oxiden mit Polyfluorcarbonen auch bei Einhalten vorgebener Extrusionsbedingungen zu Monofilen noch verbesserungsbedürftig sind, da die Dimensionsstabilität infolge hoher Toleranzen und auch ein hoher und ungleichmäßiger Schrumpf und nicht glatte Oberflächen sowie Aufspleißen der Monofile bei dickeren Durchmessern als nachteilig empfunden werden.The invention is particularly concerned with the production of high-temperature-resistant monofilaments based on suitable thermoplastics, such as polyphenylene sulfide, which has a crystallite melting point of about 285 ° C., see also Zeitschrift Kunststoffe, 77 (1987), pp. 1023-1027. Because of their high crystallinity, however, fibers and monofilaments of polyarylene sulfides and oxides tend to be brittle. Attempts have therefore already been made to improve the suppleness and processability of polyphenylene sulfide for producing monofilaments by adding polyfluorocarbons, in particular polytetrafluoroethylene, as has become known, for example, from EP-OS 0221 691 or US Pat. No. 4,493,917. However, it has been found that the Processing the binary mixtures of polyarylene sulfides or oxides with polyfluorocarbons, even if the specified extrusion conditions for monofilaments, are still in need of improvement, since the dimensional stability due to high tolerances and also a high and uneven shrinkage and non-smooth surfaces and fanning out of the monofilaments are perceived as disadvantageous in the case of thicker diameters .
Aus der US-PS 4528 335 ist eine Formmasse aus Polyarylensulfiden mit Zusatz von amorphen Polyamiden, worunter im wesentlichen nichtkristalline Polyamide mit einer Kristallinität unter 20 %, bevorzugt unter 5 %, verstanden werden, bekannt, die sich auf Grund des breiten Schmelzbereiches insbesondere für die Herstellung von Artikeln durch Spritzguß eignet.From US-PS 4528 335 a molding compound made of polyarylene sulfides with the addition of amorphous polyamides, which are understood to be essentially non-crystalline polyamides with a crystallinity of less than 20%, preferably less than 5%, are known, which are particularly suitable for the Production of articles by injection molding is suitable.
Der Erfindung liegt die Aufgabe zugrunde, eine Formmasse zu schaffen, mit der Monofile auf Basis von linearen Polyarylenoxiden bzw. -sulfiden mit guten Extrusionseigenschaften und verringerter Sprödigkeit hergestellt werden können. Im Gegensatz zu für das Spritzgießen oder normale Extrudieren geeigneten Formmassen müssen solche für das Extrudieren von Monofilen auch noch verstreckbar sein.The invention has for its object to provide a molding composition with which monofilaments based on linear polyarylene oxides or sulfides can be produced with good extrusion properties and reduced brittleness. In contrast to molding compositions suitable for injection molding or normal extrusion, those for the extrusion of monofilaments must also be stretchable.
Die Erfindung löst die gestellte Aufgabe mit einem Verfahren und einer ternären Formmasse wobei als Komponente A teilkristalline Polyarylensulfide oder -oxide, als Komponente B kristalline bzw. teilkristalline Polyamide und als Komponente C apolare Polyfluorolefine verwendet werden, die Mischungen in Extrudern bei Temperaturen oberhalb 270°C aufgeschmolzen und homogenisiert werden und die extrudierten Monofile im Verhältnis 1 zu 3 bis 1 zu 8 bei Raumtemperatur bzw. Temperaturen bis 110°C verstreckt werden. Mit der ausgewählten ternären Formmasse gelingt es, einerseits die guten Eigenschaften der Polyarylensulfide bzw. -oxide zu erhalten und gleichzeitig die Verarbeitbarkeit zu verbessern und die Sprödigkeit bzw. Kälteempfindlichkeit herabzusetzen. Mit der erfindungsgemäßen ternären Formmasse gelingt eine Optimierung der herzustellenden Produkte, insbesondere der durch Extrusion herzustellenden Monofile, die nachfolgend verstreckt werden, die überraschenderweise nicht zu Lasten einzelner Eigenschaften geht. Während bei Einsatz von binären Formmassen stets die Verbesserung einer Eigenschaft direkt verbunden ist mit einer deutlichen Verschlechterung anderer Eigenschaften, gelingt es durch die Erfindung in überraschender Weise bei Ausgleich negativer Eigenschaften die vorhandenen positiven Eigenschaften zu erhalten.The invention solves the stated problem with a process and a ternary molding composition wherein partially crystalline polyarylene sulfides or oxides are used as component A, crystalline or partially crystalline polyamides as component B and apolar polyfluoroolefins as component C, the mixtures in extruders at temperatures above 270 ° C. are melted and homogenized and the extruded monofilaments are drawn in a ratio of 1 to 3 to 1 to 8 at room temperature or temperatures up to 110 ° C. With the selected ternary molding compound, it is possible on the one hand to maintain the good properties of the polyarylene sulfides or oxides and at the same time to improve the processability and to reduce the brittleness or sensitivity to cold. Optimization is achieved with the ternary molding composition according to the invention the products to be produced, in particular the monofilaments to be produced by extrusion, which are subsequently stretched and which, surprisingly, does not come at the expense of individual properties. While the use of binary molding compositions always directly improves the property with a significant deterioration of other properties, the present invention surprisingly succeeds in maintaining the existing positive properties by compensating negative properties.

Als Komponente B werden insbesondere die kristallinen Polyamid 6, Polyamid 66 und Polyamid 610, aber auch halbaromatische teilkristalline Polyamide, wie das Poly-m-Xylylenadipamid, eingesetzt. Von den Polyamiden ist das Polyamid 66 das bevorzugt, es ergibt eine Verbesserung der Oberfläche und günstigeres Dehnungs- und Festigkeitsverhalten der Monofile.According to the invention, component A uses polyphenylene sulfide (PPS), polyphenylene oxide (PPO) or polyether ether ketones (PEEK), of which PPS is preferred. The component B used are, in particular, the crystalline polyamide 6, polyamide 66 and polyamide 610, but also semi-aromatic semi-crystalline polyamides, such as the poly-m-xylylene adipamide. Of the polyamides, the polyamide 66 is the preferred, it results in an improvement of the surface and more favorable elongation and strength behavior of the monofilaments.
Von den apolaren Fluorolefinen werden insbesondere Polytetrafluorethylen (PTFE), Tetrafluorethylen-Perfluorpropylen-Copolymere (FEP) mit 15 bis 25 % Mol-% Hexafluorpropylen, Copolymere von Fluorethylen mit ca. 5 % Perfluoralkylvinylether (PFA), Ethylen-Chlortrifluorethylen-Copolymere (ECTFE) und/oder Ethylen-Tetrafluorethylen-Copolymere (ETFE) eingesetzt, von denen ETFE bevorzugt ist. Die eingesetzten apolaren Polyfluorolefine zeichnen sich durch extrem niedrige dielektrische Verlustfaktoren aus. Gleichzeitig verbessern sie das Extrusions- und Streckverhalten der Formmasse und die chemischen Eigenschaftswerte sowie Elastizität der Monofile u. aThe apolar fluoroolefins include, in particular, polytetrafluoroethylene (PTFE), tetrafluoroethylene-perfluoropropylene copolymers (FEP) with 15 to 25% mol% hexafluoropropylene, copolymers of fluorethylene with approx. 5% perfluoroalkyl vinyl ether (PFA), ethylene-chlorotrifluoroethylene copolymers (ECTFE) and / or ethylene-tetrafluoroethylene copolymers (ETFE) are used, of which ETFE is preferred. The apolar used Polyfluoroolefins are characterized by extremely low dielectric loss factors. At the same time, they improve the extrusion and stretching behavior of the molding compound and the chemical property values and elasticity of the monofilaments and the like. a
Monofile mit einem ausgewogenen Eigenschaftsbild erhält man erfindungsgemäß durch Einsatz PPS, PA 66 und ETFE, wobei eine Zusammensetzung gemäß den Merkmalen des Anspruchs 10 bevorzugt ist.According to the invention, monofilaments with a balanced property profile are obtained by using PPS, PA 66 and ETFE, a composition according to the features of claim 10 being preferred.
Überraschend hat sich herausgestellt, daß zur Erhöhung der Flexibilität der erfindungsgemäß hergestellten Monofile bereits geringe Mengen ausgewählter Polyamide ausreichen, die gleichzeitig die Kältefestigkeit der Formmasse verbessern und der Sprödigkeit der Polyarylensulfide bzw. -oxide entgegenwirken. Insbesondere wird auch die rauhe Oberfläche von Polyarylensulfiden durch PA geglättet.Surprisingly, it has been found that even small amounts of selected polyamides are sufficient to increase the flexibility of the monofilaments produced according to the invention, which at the same time improve the cold resistance of the molding composition and counteract the brittleness of the polyarylene sulfides or oxides. In particular, the rough surface of polyarylene sulfides is smoothed by PA.
Bei dem erfindungsgemäßen Verfahren werden bevorzugt Formmassen zum Herstellen von Monofilen mit 65 bis 84, insbesondere mit 72 bis 82 Gew.-% der Komponente A, 1 bis 10, insbesondere 1 bis 5 Gew.-% der Komponente B und 15 bis 25, insbesondere 17 bis 23 Gew.-% der Komponente C verwendet. Bei einem Gehalt von 80 bis 74 Gew.-% PPS, 2 bis 4 Gew.-% PA 66 und 22 bis 18 Gew.-% ETFE werden Monofile auf Basis PPS mit einem ausgewogenen Eigenschaftsbild bei Erhalt der wesentlichen Eigenschaften von PPS erhalten.In the process according to the invention, preference is given to molding compositions for producing monofilaments with 65 to 84, in particular 72 to 82% by weight of component A, 1 to 10, in particular 1 to 5% by weight of component B and 15 to 25, in particular 17 to 23 wt .-% of component C used.

Um hochtemperaturfeste Monofile durch Extrusion mit nachfolgender Verstreckung zu erhalten, werden bevorzugt (teil-)kristalline Thermoplaste eingesetzt, deren Kristallit-Schmelzpunkt oberhalb 240°C liegt.In order to obtain high-temperature-resistant monofilaments by extrusion with subsequent stretching, preference is given to using (partially) crystalline thermoplastics whose crystallite melting point is above 240 ° C.
Das Aufschmelzen und Homogenisieren der ternären Formmassen erfolgt bevorzugt bei Temperaturen in Bereichen zwischen 285 und 305°C, ggf. auch darüber.The melting and homogenization of the ternary molding compositions is preferably carried out at temperatures in the range between 285 and 305 ° C., possibly also above this.
