FLAME-PROTECTED IMPACT-MODIFIED BATTERY HOUSING BASED ON POLYCARBONATES II.

摘要

The invention relates to a battery housing comprising compositions containing A) between 70.0 and 90.0 wt. parts (in relation to the sum of the wt. parts of the constituents A+B+C) of a linear and/or branched aromatic polycarbonate and/or aromatic polyester carbonate, B) between 6.0 and 15.0 wt. parts (in relation to the sum of the wt. parts of the constituents A+B+C) of at least one graft polymer with B.1) between 5 and 95, preferably between 30 and 80 wt. parts, of a mixture consisting of B. l. l) between 50 and 95 wt. parts of styrol, α-methyl styrene, methyl nuclear-substituted styrene, C1-C8 alkyl methacrylate, especially methyl methacrylate, C1-C8 alkyl acrylate, especially methylacrylate, or mixtures of said compounds and B.1.2) between 5 and 50 wt. parts of acrylonitrile, methacrylonitrile C1-C8 alkyl methacrylates, especially methyl methacrylate, C1-C8 alkylacrylate, especially methylacrylate, maleic acid anhydride, C1-C4 alkyl or phenyl-N-substituted maleinimide or mixtures of said compounds on B.2) between 5 and 95, preferably between 20 and 70 wt. parts of a rubber-containing graft base based on butadiene or acrylate, C) between 2.0 and 15.0 wt. parts (in relation to the sum of the wt. parts of the constituents A+B+C) of phosphorus compounds selected from the groups of the monomer and oligomer phosphoric and phosphonic acid esters, phosphonate amines, phosphazenes and phosphinates, and mixtures of said compounds, D) between 0 and 3.0 wt. parts (in relation to the sum of the wt. parts of the constituents A+B+C) of anti-drip means, E) between 0 and 3.0 wt. parts (in relation to the sum of the wt. parts of the constituents A+B+C) of thermoplastic vinyl(co)polymer (E.1) and/or polyalkyl enterephthalate (E.2), and F) between 0 and 20.0 wt. parts (in relation to the sum of the wt. parts of the constituents A+B+C) of other additives, the compositions preferably being free of rubber-free polyalkyl(alkyl)acrylate, and all weight part indications being standardised in the present application such that the sum of the weight parts of the constituents A+B+C in the composition amount to 100.
