LAYER MATERIAL FOR CORROSION PROTECTION AND SOLAR RECEIVER HAVING SUCH A LAYER MATERIAL

摘要

A layer material for corrosion protection and to a solar receiver having such a layer material is provided. The layer material comprises a binding agent consisting of a resin containing at least one of the following substances: oligo- or polysiloxane, silicone resin, silicone, silicate, polyphosphate, and which is dissolved in a solvent, a pigment consisting of zinc microparticles having an average diameter of at least 1 um, wherein a further pigment consisting of titanium oxide or silicon oxide nanoparticles having an average diameter of no more than 100 nm is present in the layer material. The layer advantageously has a self-healing effect in addition to the corrosion protection effect thereof owing to the use of zinc particles.
