Abstract:
The invention relates to a composite component consisting of a plastic support and a multi-ply metal layer applied in a galvanizing operation, the plastic support being made of a thermoplastic composition consisting of A) 50 to 90 parts by weight of at least one aromatic polycarbonate, B) 10 to 50 parts by weight of at least one graft polymer comprising a diene-containing, rubber-elastic, particulate graft base and a vinyl (co)polymer shell, C) 0 to 15 parts by weight of at least one additive, where the sum of the parts by weight of components A) and B) in the composition is standardized to 100, (i) characterized in that the rubber content from component B in the composition is at least 6 wt %, (ii) characterized in that the ratio K/S of the weight fractions of butadiene-containing, rubber-elastic, particulate graft base from component B) in the composition (viz. K) to the sum of free—that is, not bound covalently to the rubber base in the graft polymer of component B)—vinyl (co)polymer from component B) and of any free vinyl (co)polymer from component C) in the composition (viz. S) is at least 1.5, (iii) characterized in that component A) comprises at least one monomer unit selected from the group consisting of monomer units described by the general formula (2) in which R 4  is H, linear or branched C 1 -C 10  alkyl, and R 5  is linear or branched C 1 -C 10  alkyl, and monomer units derived from bis(4-hydroxyphenyl) compounds and bridged via the 1,1′-position of a cyclic, optionally heteroatom-substituted hydrocarbon, (iv) characterized in that the fraction (A cyc ) of monomer units derived from bis(4-hydroxyphenyl) compounds and bridged via the 1,1′-position of a cyclic, optionally heteroatom-substituted hydrocarbon, based on the sum of all bisphenol-derived monomer units in component A), is in the range from 0 to 40 wt %, and, if the fraction of monomer units derived from bis(4-hydroxyphenyl) compounds and bridged via the 1,1′-position of a cyclic, optionally heteroatom-substituted hydrocarbon, based on the sum of all bisphenol-derived monomer units in component A), is in the range <5 wt %, the amount of component A) in the composition is 75 to 87 parts by weight and the amount of component B) in the composition is 13 to 25 parts by weight, and also to the use of the composite component as part of motor vehicles, electrically operated devices, household articles, solar collectors or light reflectors or as a functional element for removing heat. The composite component has high dimensional stability and good metal-to-substrate adhesion even at high service temperatures and under severe temperature fluctuations.

Claim (Index 17):
