Problems solved by technology
Welding additives with a high specific gravity compared to synthetic materials have very unfavorable sedimentation properties in liquid or molten polymers, so that it is not always possible to ensure sufficient pigment retention in the polymer during processing and in the finished product. evenly distributed in
In addition, some welding additives cannot always avoid unfavorable chemical reactions with the polymers in question, which not only affect the viscosity of the polymers in liquid or molten liquid state, but also have peeling and shearing effects on synthetic materials and their composite structures Bonding in the
There are also soldering additives that have a detrimental effect on the dissipation factor curve over a wide temperature range of 50 to 500 Hz

Embodiment Construction
[0009] In an extremely simplified embodiment, the composite material according to the invention consists of two metal layers (covering layers) and a polymer layer containing sponge iron placed between the covering layers. The number of individual layers can be increased as required, so that, for example, a five-layer composite can be produced, consisting of three metal layers and each of a polymer layer containing sponge iron placed between the metal layers.

Description
technical field [0001] The invention relates to a composite material comprising at least two metal layers and comprising at least one polymer layer disposed between the metal layers, wherein the polymer layer contains at least one welding additive. Background technique [0002] Such composite materials are known in the prior art. The respondent under the trade name Volumetric sound-absorbing composites are marketed as consisting of two steel cover sheets and a polymer layer placed between them, wherein the polymer layer can be made, for example, of acrylate, silicone, polyamide and / or polyethylene, polyester materials or Epoxy resin composition. The connection of the body-sound-absorbing composite material to other components, for example by welding, in particular resistance welding, is generally problem-free. As disclosed in US Publication 2009 / 0142538, the polymer layer is added with welding additives in order to improve electrical conductivity and adjust resistance we...
