Galvanic anode system for corrosion protection of steel and method for production thereof

Abstract

The invention relates to a galvanic anode system for the corrosion protection of steel, comprised of a solid electrolyte and a galvanic anode material, preferably zinc and its alloys, glued to the solid electrolyte or embedded in the solid electrolyte. The solid electrolyte is characterised by a high ion conductivity and comprises at least one anionic and/or cationic polyelectrolyte and/or preferably at least one compound that forms complex compounds with the anode material, preferably with zinc. The solid electrolyte is produced by applying a coating agent, preferably as an aqueous dispersion or suspension, to the steel and/or to the mineral substructure, preferably to concrete. The anode material is characterised in that it forms a galvanic element in combination with the solid electrolyte and the steel to be protected, in which the steel forms the cathode. The inventive galvanic anode system is further characterised in that the anode material is applied to the surface of the solid electrolyte as a foil, network or grid, preferably by gluing, and/or is embedded in the solid electrolyte.
