Abstract
Description
Die vorliegende Erfindung betrifft einen mehrschichtigen Schlauch mit einer Innenschicht aus einer silanvernetzten Ethylen-Copolymeren-Zusammensetzung, geeignet als Befüllschlauch für medizinische Verpackungen, beispielsweise Beutel für Blut, Blutplasma oder Infusionslösungen. Ferner betrifft die Erfindung ein Verfahren zur Herstellung eines derartigen Befüllschlauches sowie eine Verwendung von diesem.The The present invention relates to a multilayer hose with an inner layer of a silane-crosslinked ethylene copolymer composition, suitable as filling hose for medical Packaging, for example bags for blood, blood plasma or infusion solutions. Furthermore, the invention relates to a method for producing a Such filling hose as well as a use of this.
Derartige Befüllschläuche müssen unter anderem folgende Anforderungen erfüllen: Sie müssen sterilisierbar, verklebbar mit einem Polycarbonat-Konnektor und mit dem Polypropylen-Beutel verschweißbar sein.such Filling hoses must be under meet the following requirements: They must be sterilizable, bondable with a polycarbonate connector and with the polypropylene bag weldable be.
Als Sterilisationsverfahren wird üblicherweise die Gamma-Strahlen-Sterilisation angewandt, zunehmend setzt sich jedoch die aus medizinischen Gründen und Umweltgründen bevorzugte Dampfsterilisation durch.When Sterilization procedure becomes common the gamma-ray sterilization is applied, increasingly settling however, for medical reasons and environmental reasons preferred steam sterilization by.
Befüllschläuche werden aus einer Vielzahl von Polymeren hergestellt. Im Bereich der Thermoplaste wird nach wie vor vor allem Poly(vinylchlorid) eingesetzt.Be filling hoses made from a variety of polymers. In the field of thermoplastics will still mainly poly (vinyl chloride) used.
PVC-Schläuche haben jedoch den Nachteil, dass sie in einer flexiblen Einstellung nicht dampfsterilisierbar sind, weiterhin dass sie Weichmacher enthalten, die ausgewaschen werden können und dass sie beispielsweise wegen der Entwicklung von Chlorwasserstoff – und gegebenenfalls Dioxin – nicht in herkömmlichen Müllverbrennungsanlagen entsorgt werden können.PVC hoses have however, the disadvantage that they are not in a flexible setting steam-sterilizable, furthermore that they contain plasticizers, which can be washed out and that, for example, because of the evolution of hydrogen chloride - and optionally Dioxin - not in conventional incinerators can be disposed of.

sind bekannt. In der
Ein
derartiger Mehrschichtschlauch kann gemäß
Strahlenvernetztes Ethylen-Vinylacetat-Copolymeres als Innenschicht in einem 2-Schichtschlauch zusammen mit einer Außenschicht aus einem compoundiertem Poly(propylen) wird in WO 97/41820 beschrieben.Reticulated Ethylene-vinyl acetate copolymer as an inner layer in a 2-layer hose together with an outer layer from a compounded poly (propylene) is described in WO 97/41820.
Die
Strahlenvernetzung der Mehrschichtschläuche nach
Aufgrund der geometrischen
Anordnung der Schläuche – aufgewickelt
als Schlauchbund auf Rollen – wird
bei der Strahlenvernetzung die Schlauchkrümmung durch die gleichzeitig
stattfindende Vernetzungsreaktion fixiert. Dies wirkt sich insbesondere
nachteilig bei der Weiterverarbeitung der Schläuche aus. Auch kommt es zu
einer unhomogenen Vernetzungsreaktion mit starken Schwankungen im
Vernetzungsgrad.The radiation crosslinking of the multilayer hoses after
Due to the geometric arrangement of the hoses - wound up as a coil on rolls - the tube curvature is fixed by the simultaneous cross-linking reaction during radiation cross-linking. This has a particularly detrimental effect on the further processing of the hoses. Also, there is an unhomogeneous crosslinking reaction with strong fluctuations in the degree of crosslinking.
Weiterhin: Da ein relativ hoher Vernetzungsgrad erreicht werden muss (80%) ist eine hohe Bestrahlungsdosis vorzugeben. Diese führt zu einer starken Abspaltung von Essigsäuremolekülen, so dass sich negative Auswirkungen auf die Infusionslösungen ergeben, insbesondere durch Reduzierung des pH-Wertes.Farther: Since a relatively high degree of networking must be achieved (80%) a high dose of radiation is required. This leads to a strong cleavage of acetic acid molecules, so that there are negative effects on the infusion solutions, in particular by reducing the pH.
Sehr nachteilig hat sich bei der Strahlenvernetzung der 2- oder 3-Schichtschläuche nach dem Stand der Technik die Bestrahlung der Außenschicht aus Poly(propylen) oder einem Poly(propylen)-Compound erwiesen. Hier kommt es zu einer starken Erwärmung – verbunden mit einem beginnenden Polymerabbau – an der Außenseite der Schläuche, so dass diese teilweise miteinander verschweißen. Daher sind Probleme bei der Weiterverarbeitung der Schläuche und dem Abwickeln von den Schlauchbunden unvermeidlich.The irradiation of the outer layer of poly (propylene) or a poly (propylene) compound has a very disadvantageous effect on the crosslinking of the 2 or 3-layer hoses according to the prior art grasslands. Here, there is a strong warming - associated with a beginning polymer degradation - on the outside of the hoses, so that they partially weld together. Therefore, problems in the further processing of the hoses and the unwinding of the hose collars are inevitable.
Nachteilig an diesem Stand der Technik ist, dass Ethylen-Copolymere mit einem Vinylacetatgehalt von größer 35 Gewichtsprozent keine oder nur eine sehr geringe Kristallinität, aufweisen, ihre Schmelzpunkte liegen unter 50°C, so dass eine effektive Vortrocknung unmöglich ist. Derartige Zusammensetzungen führen deshalb zu Vorvernetzungen und damit zu einer rauen Oberfläche, so dass diese für Befüllschläuche für Medizinprodukte nicht einsetzbar sind. Eine beispielsweise opake Ausführungsform mit einem einwandfreien Oberflächenausfall ist mit diesen Zusammensetzungen undenkbar.adversely In this state of the art is that ethylene copolymers with a Vinyl acetate content of greater than 35 weight percent have no or only a very low crystallinity, their melting points are below 50 ° C, so that effective pre-drying is impossible. Such compositions to lead therefore to pre-crosslinks and thus to a rough surface, so that this for Filling hoses for medical devices can not be used. An example opaque embodiment with a flawless surface failure is unthinkable with these compositions.

Aufgabe der vorliegenden Erfindung ist es daher, einen Befüllschlauch zur Verfügung zu stellen, der die Nachteile des Standes der Technik nicht aufweist und demgemäß dampfsterilisierbar und blutkompatibel ist, keine herstellungsbedingte, fixierte Schlauchkrümmung oder verklebte Oberfläche aufweist, der über eine einwandfreie Oberfläche verfügt, die frei von Einschlüssen oder Defekten, also stippenfrei ist und in transparenter bis opaker Ausführungsform hergestellt werden kann.task It is therefore the object of the present invention to provide a filling hose to disposal to provide that does not have the disadvantages of the prior art and steam sterilizable accordingly and blood compatible, no production-related, fixed tube curvature or glued surface that has over a perfect surface features, the free of inclusions or defects, so is speck-free and in transparent to opaque embodiment can be produced.
Erfindungsgemäß gelingt die Lösung der Aufgabe durch einen mehrschichtigen Befüllschlauch mit einer Außenschicht aus Polypropylen und einer Innenschicht aus einem silanvernetzten Ethylen-Copolymeren wobei die Innenschicht zusammengesetzt ist aus
- a) einer Polymerkomponente aus Ethylen-Vinylacetat-Copolymeren oder einem Ethylen-(Alkyl)acrylat-Copolymeren mit einem Comonomergehalt von 20-35 Gewichtsprozent und
- b) einer Silankomponente bestehend aus Vinyltriethoxysilan, einem organischen Peroxid mit einem Gehalt von kleiner/gleich 4,5 Gewichtsprozent bezogen auf Vinyltriethoxysilan, einem Kondensationskatalysator mit einem Gehalt von kleiner/gleich 1,0 Gewichtsprozent bezogen auf Vinyltriethoxysilan und einem Radikalüberträger mit einem Gehalt zwischen 0.25-0.50 Gewichtsprozent bezogen auf Vinyltriethoxysilan.
- a) a polymer component of ethylene-vinyl acetate copolymers or an ethylene (alkyl) acrylate copolymer having a comonomer content of 20-35 weight percent and
- b) a silane component consisting of vinyltriethoxysilane, an organic peroxide with a content of less than or equal to 4.5 percent by weight based on vinyltriethoxysilane, a condensation catalyst with a content of less than or equal to 1.0 percent by weight based on vinyltriethoxysilane and a radical transfer agent with a content between 0.25 -0.50 weight percent based on vinyltriethoxysilane.
Erfindungsgemäß hat sich gezeigt, dass eine Reihe von Bedingungen zur Lösung der Aufgabe erforderlich sind:
- – Die Polymerkomponente in der Innenschicht des erfindungsgemäßen Befüllschlauches ist ein Ethylen-Vinylacetat-Copolymeres, Ethylen-Methylacrylat-Copolymeres, Ethylen-Butylacrylat-Copolymeres oder ein Ethylen-Ethylhexylacrylat-Copolymeres mit einem Comonomer-Gehalt von größer 20 Gewichtsprozent, insbesondere größer 25 Gewichtsprozent, jedoch nicht größer 35 Gewichtsprozent. Die erfindungsgemäße Beschränkung auf den Bereich des Comonomergehaltes zwischen 20 und 35 Gewichtsprozent hat mehrere Gründe: Schläuche mit einem Anteil an Comonomer kleiner 20 Gewichtsprozent weisen eine zu geringe Flexibilität auf. Ist der Comonomergehalt größer 35 Gewichtsprozent hat das Polymer viele Stellen, insbesondere im Bereich der tertiären C-Atome, die leicht Radikale bilden und daher eine Vorvernetzung stark begünstigen. Weiterhin macht der niedrige Schmelzpunkt eine effektive Vortrocknung schwierig. Zum Dritten und besonders gravierend wirkt die während der Verarbeitung abgespaltene Essigsäure als Kondensationskatalysator und führt zu starken Vorvernetzungen während der Verarbeitung.
- – Als Organosilan wird ausschließlich Vinyltriethoxysilan eingesetzt, da nur damit die katalysierte Kondensation während der Direktextrusion ohne unerwünschte Vorvernetzungserscheinungen im Extruder abläuft.
- – Die bevorzugten radikalerzeugenden Komponenten sind organische Alkylperoxide mit Halbwertszeiten von 0.1 h bei Temperaturen > 80°C, insbesondere 2,5-Dimethyl-2,5-di(tertbutylperoxo)hexan und/oder 2,5-Dimethyl-2,5-di(tertbutylperoxo)3-hexin und/oder Di(tertbutyl)peroxid und/oder 1,3-Di(tertbutyl-peroxoisopropyl)benzol und/oder Dicumylperoxid und/oder Tertbutylcumylperoxid und/oder Butyl-4,4-bis(tert-butylperoxy)valerat und/oder 1,1-Bis(tert-butylperoxy)-3,3,5-trimethoxycyclohexan und/oder Tert-butylperoxobenzoat. Aufgrund der Reaktivität der erfindungsgemäßen Ethylen-Copolymere muss der Gehalt an organischem Peroxid auf kleiner/gleich 4.5% bezogen auf Vinyltriethoxysilan reduziert werden.
- – Der bevorzugte Kondensationskatalysator ist ausgewählt aus der Gruppe Dibutyl zinndilaurat, Dibutylzinnoxid, Zinnoctoat, Dibutylzinnmaleat oder Titanylacetonat. Zur Steuerung der Reaktivität beträgt der Gehalt an Kondensationskatalysator kleiner/gleich 1.0% bezogen auf Vinyltriethoxysilan.
- – Weiterhin wird ein Radikalüberträger in der speziellen Silanzusammensetzung verwendet. Dieser reagiert wesentlich schneller mit den gebildeten Radikalstellen als dass es zu einer unerwünschten Kohlenstoff-Kohlenstoff-Bindungsbildung (peroxidische Vorvernetzung) kommen kann. Bevorzugte Radikalüberträger sind Wasserstoffdonatoren wie 4-Nonen, N,N-Dimethylanilin, 1-Dodecen oder Isopropylbenzol oder doppelbindungshaltige Substanzen wie Styrol. Der Gehalt an Radikalüberträger beträgt zwischen 0.25-0.50% bezogen auf Vinyltriethoxysilan.
- The polymer component in the inner layer of the filling hose according to the invention is an ethylene-vinyl acetate copolymer, ethylene-methyl acrylate copolymer, ethylene-butyl acrylate copolymer or an ethylene-ethylhexyl acrylate copolymer having a comonomer content of greater than 20 percent by weight, in particular greater than 25 percent by weight, but not greater than 35 weight percent. The inventive restriction to the range of comonomer content between 20 and 35 weight percent has several reasons: Hoses with a proportion of comonomer less than 20 percent by weight have too low flexibility. If the comonomer content is greater than 35 percent by weight, the polymer has many sites, in particular in the region of the tertiary C atoms, which readily form free radicals and therefore strongly favor precrosslinking. Furthermore, the low melting point makes effective pre-drying difficult. Thirdly and especially seriously, the acetic acid split off during processing acts as a condensation catalyst and leads to strong precrosslinking during processing.
- - As the organosilane only vinyltriethoxysilane is used, since only so that the catalyzed condensation during the direct extrusion takes place without unwanted Vorvernetzungserscheinungen in the extruder.
- The preferred free radical generating components are organic alkyl peroxides having half lives of 0.1 h at temperatures> 80 ° C, in particular 2,5-dimethyl-2,5-di (tert-butylperoxo) hexane and / or 2,5-dimethyl-2,5-di (tert-butylperoxo) 3-hexyne and / or di (tert-butyl) peroxide and / or 1,3-di (tert-butylperoxoisopropyl) benzene and / or dicumyl peroxide and / or tert-butylcumyl peroxide and / or butyl-4,4-bis (tert-butylperoxy ) valerate and / or 1,1-bis (tert-butylperoxy) -3,3,5-trimethoxycyclohexane and / or tert-butylperoxobenzoate. Due to the reactivity of the ethylene copolymers of the invention must Content of organic peroxide reduced to less than or equal to 4.5% based on vinyltriethoxysilane.
- The preferred condensation catalyst is selected from the group consisting of dibutyltin dilaurate, dibutyltin oxide, tin octoate, dibutyltin maleate or titanylacetonate. To control the reactivity of the content of condensation catalyst is less than or equal to 1.0% based on vinyltriethoxysilane.
- Furthermore, a radical transfer agent is used in the specific silane composition. This reacts much faster with the formed radical sites than that it can lead to an undesirable carbon-carbon bond formation (peroxidic pre-crosslinking). Preferred radical transfer agents are hydrogen donors such as 4-nonene, N, N-dimethylaniline, 1-dodecene or isopropylbenzene or double bond-containing substances such as styrene. The content of radical transfer is between 0.25-0.50% based on vinyltriethoxysilane.
Durch Verwendung der polaren Ethylen-Copolymeren mit einem Comonomergehalt von 20-35 Gewichtsprozent in Kombination mit der in Art und Menge erfindungsgemäßen Silanzusammensetzung in der Innenschicht des Befüllschlauches können die im Stand der Technik beschriebenen Schwierigkeiten wie Fixierung der Schlauchkrümmung, schwankender Vernetzungsgrad oder das Zusammenkleben der Schläuche vermieden werden. Es ist ein dampfsterilisierbarer und blutkompatibler Befüllschlauch in transparenter bis opaker Ausführungsform herstellbar.By Use of the polar ethylene copolymers having a comonomer content from 20-35% by weight in combination with in kind and quantity silane composition according to the invention in the inner layer of the filling hose can the difficulties described in the prior art, such as fixation the hose bend, fluctuating degree of crosslinking or sticking of the tubes avoided become. It is a steam sterilizable and blood compatible filling tube in transparent to opaque embodiment produced.
Erfindungsgemäß weist der Innenschlauch aus der silanvernetzten Ethylen-Copolymeren-Zusammensetzung einen Gelgehalt zwischen 50 und 70 %, insbesondere zwischen 50 und 60 % auf.According to the invention the inner tube of the silane-crosslinked ethylene copolymer composition a gel content between 50 and 70%, in particular between 50 and 60% up.
Die eingangs genannte Aufgabe wird, was das Herstellungsverfahren betrifft, dadurch gelöst, dass bei der Herstellung des erfindungsgemäßen Befüllschlauches eine Propfungsreaktion des Vinyltriethoxysilans auf das Ethylen-Copolymere, eine Formgebung und eine Aufbringung der Außenschicht über einen Zuspritzextruder in einem Verarbeitungsschritt gleichzeitig erfolgt (Direktextrusion) und dabei ein Einschneckenextruder mit Barriereschnecke als Verarbeitungsaggregat zum Einsatz kommt.The the object mentioned at the outset becomes, with regard to the manufacturing process, solved by that in the preparation of the filling tube according to the invention, a grafting reaction Vinyltriethoxysilans on the ethylene copolymer, a molding and a Application of the outer layer over a Injection extruder in a single processing step takes place simultaneously (Direct extrusion) and a single-screw extruder with barrier screw is used as a processing unit.
Der Befüllschlauch kann durch Coextrusion der Polypropylen-Außenschicht mit der Innenschicht hergestellt werden, wobei zur Herstellung der Innenschicht im Extruder Vinyltriethoxysilan auf das Ethylen-Copolymere unter Zugabe eines organischen Peroxids, eines Kondensationskatalysators und eines Radikalüberträgers in der beschriebenen Zusammensetzung aufgepfropft, der Befüllschlauch gleichzeitig ausgeformt (Direktextrusion) und anschließend – in einem separaten Arbeitsgang – mittels Feuchtigkeit vernetzt wird.Of the filling hose can be achieved by coextrusion of the polypropylene outer layer with the inner layer are prepared, wherein for the production of the inner layer in the extruder Vinyltriethoxysilane on the ethylene copolymer with the addition of a organic peroxide, a condensation catalyst and a Radical transfer agent in grafted the described composition, the filling tube molded simultaneously (direct extrusion) and then - in one separate operation - by Moisture is crosslinked.
