Abstract

Flame-resistant, thermoplastic polymer mixtures are described which contain two ethylene vinyl acetate copolymers having different vinyl acetate contents, an ethylene-propylene copolymer and an acrylate copolymer. The flame resistance of the mixtures is effected by aluminium hydroxide as filler, which has a specific surface area of less than 10 m<2>/g.

Description

Die Erfindung bezieht sich auf eine thermoplastische Polymermischung gemäß dem Oberbegriff des Hauptanspruchs.The invention relates to a thermoplastic polymer mixture according to the preamble of the main claim.

Derartige Polymermischungen sind aus der DE-PS 30 47 269 bekannt. Sie enthalten ein Äthylen Vinylacetat-Copolymer, mit mindestens 38% Vinylacetat-Anteil, ein weiteres Äthylencopolymer mit mindestens 70% Äthylen-Anteil sowie Flammwidrigkeit bewirkende Füllstoffe mit hohem Füllgrad und weitere Zusatzstoffe.Such polymer mixtures are from DE-PS 30 47 269 known. They contain an ethylene vinyl acetate copolymer, with at least 38% vinyl acetate, another ethylene copolymer with at least 70% ethylene content as well Flame-retardant fillers with a high degree of filling and other additives.

Es ist die Aufgabe der Erfindung eine halogenfreie, flammwidrige Polymermischung anzugeben, die den Anforderungen der VDE-Norm 0207 Teil 24 entspricht, aber trotz hohem Füllgrad eine relativ niedrige Schmelzviskosität besitzt.It is the object of the invention a halogen-free, flame-retardant Polymer blend to specify the requirements complies with VDE standard 0207 part 24, but despite high Filling degree has a relatively low melt viscosity.

Diese Aufgabe ist durch eine Polymermischung gemäß dem Hauptanspruch gelöst. In den Unteransprüchen sind vorteilhafte Ausgestaltungen enthalten. This object is achieved by a polymer mixture according to the Main claim solved. In the subclaims are advantageous Refinements included.  

Die neuen Polymermischungen besitzen gegenüber der bekannten Polymermischung eine verbessere Verarbeitbarkeit, da sie eine niedrigere Schmelzviskosität besitzen. Dies wird durch den Zusatz eines Acrylat-Copolymers bewirkt, das durch seine Hydrophobie der Mischung außerdem eine hohe Widerstandsfähigkeit gegen Feuchtigkeit, insbesondere auch bei höheren Temperaturen verleiht. Die mechanischen und die Isolationseigenschaften werden dadurch nicht negativ beeinflußt.The new polymer mixtures have compared to the known Polymer blend an improved processability, because they have a lower melt viscosity. this will caused by the addition of an acrylate copolymer that due to the hydrophobicity of the mixture, it is Resistance to moisture, especially gives at higher temperatures. The mechanical and this does not make the insulation properties negative influenced.

Ferner besitzen die neuen Polymermischungen aufgrund des Zusatzes des Acrylat-Copolymers und eines Äthylen-Propylen- Copolymers höhere Festigkeitswerte ohne eine Verschlechterung der Reißdehnung, und ohne ein schlechteres Brandverhalten in Kauf nehmen zu müssen. Der Zusatz des Äthylen-Propylen-Copolymers bewirkt außerdem eine Verbesserung der elektrischen Eigenschaften der Polymermischung.Furthermore, the new polymer blends have due to the Addition of the acrylate copolymer and an ethylene-propylene Copolymers have higher strength values without deterioration the elongation at break, and without a worse one Having to put up with fire behavior. The addition of the Ethylene-propylene copolymer also brings about an improvement the electrical properties of the polymer blend.

Die Erfindung wird nachstehend anhand zweier Beispiele erläutert. In beiden Beispielen enthalten die Polymermischungen zwei verschiedene Äthylenvinylacetat(EVA)-Copolymere mit unterschiedlichen Vinylacetat-Anteilen (VA), ein Äthylen-Propylen-Copolymer (EPR) und/ohne ein Äthylen- Propylen-Dien-Copolymer (EPDM), ein Acrylat-Copolymer und Aluminiumhydroxid als die Flammwidrigkeit bewirkenden Füllstoff. Die spezifische Oberfläche des Aluminiumhydroxyds beträgt vorteilhafterweise weniger als 10 m2/g, da sonst die Schmelzviskosität der Polymermischung zu groß ist. Die Copolymere sind so aufeinander abgestimmt, daß ein hoher Füllgrad möglich ist, und die Mischungen trotzdem gut verarbeitbar sind. Ferner enthalten die Mischungen Zusatzstoffe, wie beispielsweise Alterungsschutzmittel, Haftvermittler o. ä.The invention is explained below using two examples. In both examples, the polymer blends contain two different ethylene vinyl acetate (EVA) copolymers with different vinyl acetate proportions (VA), an ethylene-propylene copolymer (EPR) and / without an ethylene-propylene-diene copolymer (EPDM), an acrylate Copolymer and aluminum hydroxide as the flame retardant filler. The specific surface area of the aluminum hydroxide is advantageously less than 10 m 2 / g, since otherwise the melt viscosity of the polymer mixture is too high. The copolymers are matched to one another in such a way that a high degree of filling is possible and the mixtures are nevertheless easy to process. The mixtures also contain additives, such as anti-aging agents, adhesion promoters or the like.
