Description

Die Erfindung betrifft elektrische Isolierteile gemäß dem Oberbegriff des Anspruchs 1 und insbesondere Umhüllungen für elektrische Leiter und Kabel.The invention relates to electrical insulating parts according to the preamble of claim 1 and in particular sheaths for electrical conductors and cables.

Verschiedene Kunststoffarten werden als Isoliermaterial für elektrische Bauteile verwendet. Besonders geeignet sind Polyester, die gute elektrische Isoliereigenschaften auf­weisen. Das Isoliermaterial kann als Schlauch über ein elektrisches Kabel gezogen werden oder direkt auf das zu isolierende Teil aufgespritzt werden. Ebenso ist es möglich, den Isolierwerkstoff in Form einer Folie bzw. eines Films um den elektrischen Leiter zu wickeln. Dabei wird die Folie in mehreren Lagen übereinander gewickelt, um so eine möglichst gute elektrische Isolierung zu erreichen. Wird eine Polyesterfolie verwendet, lassen sich die einzelnen Lagen nicht verschweißen und nicht untereinander verbinden. Daher ist eine Beschichtung mit Zusatzstoffen notwendig, die hohe Kohäsionskräfte besitzen, um die einzelnen gewickelten Folien­lagen miteinander mechanisch verbinden zu können.Various types of plastic are used as insulation material for electrical components. Polyesters with good electrical insulation properties are particularly suitable. The insulating material can be pulled as a hose over an electrical cable or sprayed directly onto the part to be insulated. It is also possible to wind the insulating material around the electrical conductor in the form of a film. The film is wound in several layers on top of one another in order to achieve the best possible electrical insulation. If a polyester film is used, the individual layers cannot be welded and cannot be connected to one another. A coating with additives that have high cohesive forces is therefore necessary in order to be able to mechanically connect the individual wound film layers to one another.

Um das Altern oder Brüchigwerden der Polyesterfolie zu ver­hindern oder erheblich zu verlangsamen, wird diese Folie mit Stabilisatoren bzw. Alterungsschutzmitteln versehen. Weiter­hin ist es bekannt, die Polyesterfolie mit Farbzusätzen zu versehen.In order to prevent or considerably slow down the aging or breakage of the polyester film, this film is provided with stabilizers or anti-aging agents. It is also known to add color additives to the polyester film.

Da die Polyesterfolie leicht entzündlich und brennbar ist, wird sie mit flammhemmenden bzw. -widrigen Mitteln ausge­rüstet. Technisch wichtige Flammschutzmittel enthalten mindestens eines der folgenden Elemente:
Phosphor, Antimon, Chlor, Brom oder Stickstoff. Bekannte Flammschutzmittel für Kunststoffe sind chlorierte Paraffine, hochchlorierte bicyklische Verbindungen und Bromverbindun­gen. Die organischen Halogenverbindungen werden immer zusam­men mit Antimontrioxid angewandt. Auch anorganische Phosphor­verbindungen, organische Phosphonsäuren oder halogenierte Phosphorverbindungen sind in Flammschutzmitteln für Kunst­stoffe häufig anzutreffen.Since the polyester film is highly flammable and flammable, it is equipped with flame retardant or flame retardant agents. Technically important flame retardants included at least one of the following:
Phosphorus, antimony, chlorine, bromine or nitrogen. Known flame retardants for plastics are chlorinated paraffins, highly chlorinated bicyclic compounds and bromine compounds. The organic halogen compounds are always used together with antimony trioxide. Inorganic phosphorus compounds, organic phosphonic acids or halogenated phosphorus compounds are also frequently found in flame retardants for plastics.

Allerdings ist der Einsatz von solchen Flammschutzmitteln in Kunststoffen insofern nachteilig, als die halogenierten Flammschutzmittel bei der Verbrennung die Atmosphäre be­lasten und toxische und stark korrodierende Wirkungen be­sitzen.However, the use of such flame retardants in plastics is disadvantageous in that the halogenated flame retardants pollute the atmosphere during combustion and have toxic and highly corrosive effects.

Es besteht daher ein Bedürfnis an flammwidrigen Beschich­tungen für Isoliermaterialien interessiert, die halogenfrei sind. Es werden bereits einige halogenfreie Flammschutzmittel eingesetzt. Jedoch haben diese den Nachteil, daß die Menge an Flammschutzmittel beträchtlich erhöht werden muß, um die gleiche flammhemmende Wirkung zu erbringen wie die halogen­haltigen Flammschutzmittel. Die Forderung nach Schwerent­flammbarkeit führt in diesen Fällen zu einem Verzicht auf einige der typischen Eigenschaften, zum Beispiel der Güte der mecha­nischen Eigenschaften.There is therefore a need for flame retardant coatings for insulating materials that are halogen free. Some halogen-free flame retardants are already used. However, these have the disadvantage that the amount of flame retardant must be increased considerably in order to produce the same flame retardant effect as the halogen-containing flame retardants. In these cases, the requirement for flame retardancy means that some of the typical properties, for example the quality of the mechanical properties, are dispensed with.

Der Erfindung liegt die Aufgabe zugrunde, elektrische Isolier­teile verfügbar zu machen, die mit einer flammwidrigen Be­schichtung versehen sind. Die flammwidrige Beschichtung soll dabei nicht zu einer Beeinträchtigung der
Eigenschaften des Isoliermaterials führen.The invention has for its object to make available electrical insulating parts which are provided with a flame-retardant coating. The flame-retardant coating is not intended to impair the
Properties of the insulating material.

Eine weitere Aufgabe der Erfindung ist es, Verbindungen für eine flammfeste Beschichtung zu verwenden, die im Brandfall nicht zu toxischen oder korrodierend wir­kenden Produkten führen.Another object of the invention is to use connections for a flame-resistant coating, that do not lead to toxic or corrosive products in the event of fire.

Eine Lösung dieser Aufgabe ist im Anspruch 1 angegeben und kann den weiteren Ansprüchen gemäß vorteilhaft weitergebil­det werden.A solution to this problem is specified in claim 1 and can advantageously be developed according to the other claims.

Die elektrischen Isolierteile, die aus der Polyesterfolie und der erfindungsgemäßen halogenfreien vernetzbaren Be­schichtung hergestellt sind, zeichnen sich durch verbes­serte mechanische Eigenschaften, stark verminderte Rauch­gasdichte und durch eine bessere adhäsive Verbindung der einzelnen gewickelten Polyesterlagen aus. Bei Anwendung dieser Beschichtung auf dem Polyester wird eine umfassende Sicherheit erreicht, da im Brandfall die Toxizität und die Korrosivität der Rauchgase erheblich vermindert wird.The electrical insulating parts which are produced from the polyester film and the halogen-free crosslinkable coating according to the invention are distinguished by improved mechanical properties, greatly reduced smoke density and by a better adhesive bond between the individual wound polyester layers. Comprehensive safety is achieved when this coating is applied to the polyester, since the toxicity and corrosiveness of the flue gases are significantly reduced in the event of a fire.

Die erfindungsgemäßen elektrischen Isolierteile sind aus Polyester, vorzugsweise in Folienform, und einer flammwidri­gen Beschichtung hergestellt, die eine vernetzte halogenfreie Mischung von ungesättigtem Polyesterharz, Ver­netzern bzw. Kettenverlängerern, Katalysatoren, Stabilisa­toren bzw. Alterungsschutzmitteln, Farbstoffen und Flamm­schutzmitteln enthält.The electrical insulating parts according to the invention are made of polyester, preferably in the form of a film, and a flame-retardant coating which contains a crosslinked halogen-free mixture of unsaturated polyester resin, crosslinking agents or chain extenders, catalysts, stabilizers or antiaging agents, dyes and flame retardants.

Die mit der Polyesterfolie und der halogenfreien Beschich­tung isolierten elektrischen Teile, insbesondere elektri­sche Leiter und Kabel zeichnen sich durch hohe Abriebfestig­keit, Kerbfestigkeit, Spannungsfestigkeit, Zugfestigkeit und Temperaturbeständigkeit bis etwa 150° C aus. Die Zusatzstoffe der Beschichtung müssen nicht in einer wesent­lich erhöhten Konzentration zugegeben werden, um zu einer ausreichenden Flammwidrigkeit zu führen.The electrical parts insulated with the polyester film and the halogen-free coating, in particular electrical conductors and cables, are characterized by high abrasion resistance, notch resistance, dielectric strength, tensile strength and temperature resistance up to approximately 150 ° C. The additives of the coating do not have to be added in a significantly increased concentration in order to lead to sufficient flame retardancy.

Die oben beschriebenen Nachteile einer verminderten Flammschutz­wirkung bzw. einer verminderten Festigkeit werden durch die Ver­wendung verschiedener Kombinationen von Flammschutzmitteln aus zwei unterschiedlichen Verbindungsgruppen eliminiert. Die erste Verbindungsgruppe enthält anorganische Phosphatester, phosphonierte Polyole, roten Phosphor und organische Phosphate. Von den organischen Phos­phaten werden vorzugsweise Alkylphosphate, Allylphosphate, Aryl­phosphate und insbesondere Trioctylphosphat, Kresylphosphat, Phenylphosphat, Kresylphenylphosphat und Ethylacetylhydroxybenzyl­phosphat eingesetzt. Verbindungen dieser ersten Gruppe werden mit Verbindungen einer zweiten Gruppe kombiniert. Diese zweite Ver­bindungsgruppe enthält Borsäure, Amoniumsulfonamide, anorganische Phosphate, Polyphosphate, Borate und Metallhydroxide. Besonders geeignete Borate sind Bariummetaborate, Zinkborate und Ammonium­borate, vorzugsweise verwendete Metallhydroxide sind Aluminium-­und Magnesiumhydroxide. Zu den geeigneten anorganischen Phosphaten sind die Borsphosphate zu zählen, zu den Polyphos­phaten die Ammoniumpolyphosphate.The above-described disadvantages of reduced flame retardancy or reduced strength are eliminated by using different combinations of flame retardants from two different connecting groups. The first linking group contains inorganic phosphate esters, phosphonated polyols, red phosphorus and organic phosphates. Of the organic phosphates, alkyl phosphates, allyl phosphates, aryl phosphates and in particular trioctyl phosphate, cresyl phosphate, phenyl phosphate, cresyl phenyl phosphate and ethyl acetyl hydroxybenzyl phosphate are preferably used. Connections from this first group are combined with connections from a second group. This second group of compounds contains boric acid, ammonium sulfonamides, inorganic phosphates, polyphosphates, borates and metal hydroxides. Particularly suitable borates are barium metaborates, zinc borates and ammonium borates; metal hydroxides which are preferably used are aluminum and magnesium hydroxides. Suitable inorganic phosphates include boron phosphates, and polyphosphates include ammonium polyphosphates.

Die verbesserte Flammwidrigkeit beruht auf einer synergisti­schen Wirkung des aus den beiden genannten Gruppen herge­stellten Flammschutzsystems. Dadurch ist eine Erhöhung der Dosierung der Flammschutzmittel nicht notwendig. Die Menge an Flammschutzmitteln aus der ersten Gruppe liegt im Bereich von 0 - 80 Gew.-%, die Menge an Flammschutzmitteln aus der zweiten Gruppe im Bereich von 0 - 70 Gew.-%. Es reichen bereits geringe Mengen an Flammschutzmitteln aus diesen beiden Grup­pen aus, um zu einer hohen Flammwidrigkeit zu gelangen. Vorzugs­weise werden 10 - 40 Gew.-% an Flammschutzmitteln aus der ersten Gruppe und 20 - 60 Gew.-% an Flammschutzmitteln aus der zweiten Gruppe eingesetzt.The improved flame retardancy is based on a synergistic effect of the flame protection system produced from the two groups mentioned. It is therefore not necessary to increase the dosage of the flame retardants. The amount of flame retardants from the first group is in the range from 0 to 80% by weight, the amount of flame retardants from the second group in the range from 0 to 70% by weight. Even small amounts of flame retardants from these two groups are sufficient to achieve high flame retardancy. Preferably 10-40% by weight of flame retardants from the first group and 20-60% by weight of flame retardants from the second group are used.

For crosslinking, at least one compound from the group of aryl or alkyl diisocyanates, the blocked polyiso cyanate, the fatty acid-modified polyisocyanate or isophorone diisocyanate or triisocyanatophenyl triphosphate selected.

Als Stabilisatoren bzw. Alterungsschutzmittel werden vor­zugsweise Verbindungen der in Ortho- oder Para-Stellung substituierten Einkern- oder Mehrkernphenole, der Bis­benzooxazole, der Cumarinderivate, Polycarbodiimide, der aromatischen Amine, Thioether, oder der Phosphite ausgewählt. Durch die Zugabe dieser Stoffe wird die un­erwünschte Änderung der chemischen und physikalischen Struktur des Isolierteils während des Gebrauchs vermie­den.Compounds of the mononuclear or polynuclear phenols substituted in the ortho or para position, the bisbenzooxazoles, the coumarin derivatives, polycarbodiimides, the aromatic amines, thioethers or the phosphites are preferably selected as stabilizers or anti-aging agents. The addition of these substances avoids the undesirable change in the chemical and physical structure of the insulating part during use.
