Beschreibung description
Die Erfindung betrifft schwerentflammbare Polyamide und daraus hergestellte Formkörper. The invention relates to flame-retardant polyamides and molded articles made therefrom.
Als flammhemmende Additive für Polymere, speziell für Polyamide gehören zum wohlbekannten Stand der Technik Melaminverbindungen, speziell Melamincyanurat, Magnesium- und Aluminium-Hydroxyd, halogenierte, speziell bromierte organische Verbindungen, besonders in Kombination mit Schwermetallsalzen, Phosphor allein und in Kombination mit halogenhaltigen Verbindungen. As flame retardant additives for polymers, especially for polyamides, the well-known prior art includes melamine compounds, especially melamine cyanurate, magnesium and aluminum hydroxide, halogenated, especially brominated organic compounds, especially in combination with heavy metal salts, phosphorus alone and in combination with halogen-containing compounds.
Diese Additive sind für Polyamide nur bedingt geeignet, da sie in sehr hohen Mengen eingesetzt werden müssen, um z.B. den Standard-Verbrennungstest UL 94-Wert Vo zu erreichen. Dadurch werden die mechanischen Eigenschaften verändert. These additives are only suitable to a limited extent for polyamides, since they have to be used in very large quantities, e.g. to achieve the standard UL 94 combustion test Vo. This changes the mechanical properties.
Aufgabe war daher, ein schwerentflammbares Polyamid zur Verfügung zu stellen, das diesen Nachteil überwindet und eine kostengünstige Flammfest-Modifizierung erlaubt. The task was therefore to provide a flame-retardant polyamide that overcomes this disadvantage and allows inexpensive flame-resistant modification.
Sie wird gelöst durch die Polyamide des Anspruchs 1. It is solved by the polyamides of claim 1.
Besonders vorteilhaft für die erfindungsgemässen Polyamide ist, dass die gelösten Phosphorsäurever-bindungen nicht migrieren und dass damit auf den Formkörpern aus den erfindungsgemässen Polyamiden keine störende Belagsbildung auftritt. It is particularly advantageous for the polyamides according to the invention that the dissolved phosphoric acid compounds do not migrate and that there is therefore no disruptive formation of deposits on the moldings made from the polyamides according to the invention.
Ein weiterer Vorteil sind die durch die gelösten flammhemmenden Additive praktisch unveränderten mechanischen Eigenschaften der Polyamide respektive ihrer Formkörper. Another advantage are the mechanical properties of the polyamides and their molded bodies, which are practically unchanged due to the dissolved flame-retardant additives.
Besonders vorteilhaft ist auch, dass die erfindungsgemässen Polyamide bereits mit Additiv-Anteilen um 4 bis 10 Gew.-% flammhemmend modifiziert sind. It is also particularly advantageous that the polyamides according to the invention have already been modified to be flame-retardant with additive components of 4 to 10% by weight.
Für ein Standardpolyamid vom Typ PA 6 oder PA 12 genügen z.B. 5 Gew.-% des flammhemmenden Additivs um den Vo-Wert im Verbrennungstest UL 94 zu erreichen. For a standard polyamide of type PA 6 or PA 12, e.g. 5% by weight of the flame retardant additive to achieve the Vo value in the UL 94 combustion test.
Als Polyamide sind alle semikristallinen Po-lyamid-Typen, ihre Mischungen und Blends zu verstehen, speziell die Homopolyamide PA 6, PA 11, PA 12, PA 66, PA 69, PA 610, PA 612, PA 1212, PA 46 aber auch solche deren Monomere ausgewählt sind aus der Gruppe aliphatische Diamine mit 4 bis 12 C-Atomen, cycloaliphatische Diamine mit 7 bis 22 C-Atomen und aromatischen Diamine mit 6 bis 22 C-Atomen in Kombination mit Monomeren der Gruppe aliphatischen Dicarbonsäuren mit 4 bis 12 C-Atomen, cycloaliphatischen Dicarbonsäuren mit 8 bis 24 C-Atomen und aromatischen Dicarbonsäuren mit 8 bis 20 C-Atomen, bevorzugt solche aus Hexamethylen und seinen Derivaten, NDT und PACM und seinen Derivaten und Homologen mit aliphatischen oder aromatischen Dicarbonsäuren mit 4 bis 36 respektive 8 bis 20 C-Atomen. All semicrystalline polyamide types, their mixtures and blends are to be understood as polyamides, especially the homopolyamides PA 6, PA 11, PA 12, PA 66, PA 69, PA 610, PA 612, PA 1212, PA 46, but also those whose monomers are selected from the group of aliphatic diamines with 4 to 12 carbon atoms, cycloaliphatic diamines with 7 to 22 carbon atoms and aromatic diamines with 6 to 22 carbon atoms in combination with monomers from the group aliphatic dicarboxylic acids with 4 to 12 carbon atoms Atoms, cycloaliphatic dicarboxylic acids with 8 to 24 C atoms and aromatic dicarboxylic acids with 8 to 20 C atoms, preferably those made from hexamethylene and its derivatives, NDT and PACM and its derivatives and homologues with aliphatic or aromatic dicarboxylic acids with 4 to 36 or 8 to 20 carbon atoms.
Das flammhemmende Additiv ist ein aliphatischer Polyolester einer alkylierten Phosphorsäure. The flame retardant additive is an aliphatic polyol ester of an alkylated phosphoric acid.
Bevorzugt ist der Trimethylpropanolester der Methylphosphorsäure. The trimethylpropanol ester of methylphosphoric acid is preferred.
Die schwerentflammbaren Formkörper aus den erfindungsgemässen Polyamiden sind in Form, Gestaltung und Grösse nicht begrenzt. The flame-retardant molded articles made from the polyamides according to the invention are not limited in shape, design and size.
