Abstract
The invention relates to flame-retardant polyamide compositions containing a polyamide having a melting point of less than or equal to 290 DEG C as component A, fillers and/or reinforcing materials ascomponent B, phosphinic acid salt of formula (I) as component C, wherein R1 and R2 represent ethyl, M represents Al, Fe, TiOp or Zn, m represents 2 to 3, and p = (4 - m) / 2, a compound selected fromthe group of Al, Fe, TiOp or Zn salts of ethyl butylphosphinic acid, dibutylphosphinic acid, ethylhexylphosphinic acid, butylhexylphosphinic acid and/or dihexylphosphinic acid as component D, phosphonic acid salt of formula (II) as component E, wherein R3 represents ethyl, Met represents Al, Fe, TiOq or Zn, n represents 2 to 3, and q = (4 - n) / 2, a melamine polyphosphate having an average degree of condensation of between 2 to 100 as component F, a sterically hindered phenolic antioxidant as component G, and/or an organic phosphite and/or organic phosphonite as component H. The polyamide compositions can be used to produce fibers, films, and moulded bodies, in particular for applications in the electrical and electronics fields.
Description
technical field [0001] The present invention relates to flame-retardant polyamide compositions and moldings produced therefrom. Background technique [0002] Combustible plastics generally have to be equipped with flame retardants in order to be able to meet the high flame retardancy requirements required by plastics processors and in some cases by legislators. Preferably, also for ecological reasons, non-halogenated flame retardant systems are used which form little or no smoke. [0003] Among these flame retardants, the salts of phosphinic acid (phosphinates) have proven to be particularly effective for thermoplastic polymers (DE 2 252 258 A and DE 2 447 727 A). [0004] It is also known that synergistic combinations of phosphinates with specific nitrogen-containing compounds are more effective as flame retardants in a series of polymers than phosphinates alone (WO-2002 / 28953 A1 and DE 197 34 437 A1 and DE 197 37727 A1). [0005] From US 7,420,007 B2 it is known that di...
