Flame-proof agent-stabiliser combination for thermoplastic and duroplastic polymers

Abstract

The invention relates to a flameproof agent stabilizer combination containing, as component A 40-99 wt. % of a phosphinic acid salt of formula (I) and/or a diphosphinic acid salt of formula (II) and/or polymers thereof, wherein R, Rare the same or different and represent C-C-alkyl linear, branched or cyclic, C-C-aryl, C-C-arylalkyl and/or C-C-alkylaryl; Rrepresents C-C-alkylene, linear or branched, C-C-arylene, C-C-alkylarylene or C-C-arylalkylene; M represents Mg, Ca, Al, Sb, Sn, Ge, Ti, Zn, Fe, Zr, Ce, Bi, Sr, Mn, Li, Na, K and/or a protoned nitrogen base; m represents 1-4; n represents 1-4; x represents 1-4, as component B 1-60 wt. % of a phosphinic acid salt of general formula (III) wherein Rrepresents C-C-alkyl linear, branched or cyclic, C-C-aryl, C-C-arylalkyl or C-C-alkylaryl and M represents Mg, Ca, Al, Sb, Sn, Ge, Ti, Zn, Fe, Zr, Ce, Bi, Sr, Mn, Li, Na, K and/or a protonated nitrogen base, as component C 0-50 wt. % of a synergist containing nitrogen and/or a phosphorous/nitrogen flameproof agent, as component D 0-10 wt. % of a zinc salt and/or a basic or amphoteric oxide, hydroxide, carbonate, silicate, borate, stannate, mixed oxide-hydroxide, oxide-hydroxide-carbonate, hydroxide-silicate and/or hydroxide-borate and/or mixtures of said substances, as component E 0-10 wt. % phosphonite or phosphonite/phosphite-mixture and as component F 0-10 wt. % ester and/or salts of long-chained fatty acids having 14-40 C-atom, the total of the components always amounting to 100 wt. %, under the proviso that if Rrepresents C-C-alkyl, then at least one of the groups Rand/or Rrepresent C-C-aryl, C-C-arylalkyl and/or C-C-alkylaryl.
