Abstract (en)

[origin: WO2020109469A1] The invention relates to flame-retardant mixtures containing: a) salt of a phosphinic acid of the formula (I), wherein R1 and R2 mean, independently of each other, alkyl-, cycloalkyl-, aryl- or aralkyl, which are substituted as applicable, M is an m-valent cation, and m means 1 to 4, b) salt of a phosphinic acid of the formula (II), which differs from component a), wherein R3 means substituted, as applicable, alkyl-, cycloalkyl-, cycloalkyl-alkyl, aryl- or aralkyl, preferably with alkyl radicals as substituents, R4 is alkyl having an even number of carbon atoms, provided that, in the case that R1 and/or R2 are alkyl, R4 has double, triple or quadruple the number of carbon atoms of R1 or R2, M is an n-valent cation and n means 1 to 4, c) organylphosphonate, d) phosphite, e) as applicable, a representative selected from the group consisting of triazine complex, polyphosphate, hypophosphite, nitrogenous diphosphate, organophosphate, phosphazene and/or polyphosphonate, f) as applicable, a representative selected from the group consisting of metal hydroxide, metal carbonate, metal borate, zinc stannate and/or intumescence additive, and g) as applicable, pigment, wherein at least one of components e) and/or f) must be present in the mixture. The mixtures can use thermoplastic and elastomeric polymers in order to produce flame-retardant polymer compositions, which are exceptionally suitable for producing cable sheathing or cable insulation.
