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

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 40 wt. %, preferably between 5 and 30 wt. %, especially preferably between 10 and 20 wt. % (respectively in relation to the graft polymer B) of an envelope consisting of at least one vinyl monomer, and B.2 between 95 and 60 wt. %, preferably between 95 and 70 wt. %, especially preferably between 80 and 90 wt. % (respectively in relation to the graft polymer B) of at least one graft base consisting of silicone-acrylate-composite rubber, 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.
