Abstract
The invention relates to plastics composite moldings obtainable via welding in an alternating electromagnetic field, in which the weld is obtained with the aid of a plastics material which comprises nano-scale, magnetic oxidic particles, which are composed of aggregated primary particles, and where the primary particles are composed of magnetic metal oxide domains whose diameter is from 2 to 100 nm in a non-magnetic metal oxide matrix or non-magnetic metalloid oxide matrix.
Claims18
A plastics composite molding, obtained by a process comprising welding in an alternating electromagnetic field,
- wherein a weld is obtained with the aid of a plastics material which comprises a nano-scale, magnetic oxidic particle, and
- wherein the plastics material that generates the weld is thermoplastically softenable,
- wherein the nano-scale, magnetic oxidic particle comprises aggregated primary particles, and
- wherein the primary particles comprise (i) magnetic metal oxide domains whose diameter is from 2 to 100 nm, in (ii) a non-magnetic metal oxide matrix or non-magnetic metalloid oxide matrix.
