A salt-like, hydrophobic structured silicate is disclosed. The cation of the salt-like structured silicate is a low-molecular organic cation or a combination thereof with an NH4<+>, H3O<+>, alkali metal, alkaline earth metal, earth metal and/or transition metal ion. The anion of the salt-like structured silicate is an island, ring, group, chain, band, layer or tectosilicate, or a combination thereof. The structured silicate is produced by (a) reacting a structured silicate whose cation is an NH4<+>, H3O<+>, alkali metal, alkaline earth metal, earth metal and/or transition metal ion or a combination thereof, and whose ion is an island, ring, group, chain, band, layer or tectosilicate, or a combination thereof, in an aqueous dispersion with a low-molecular organic cation; by (b) adding to and intensively blending with the aqueous structured silicate dispersion a hydrophobic compound from the group of waxes and metal soaps, in a quantity ranging from 0.2 to 200 % by weight of the salt-like structured silicate in step (a), before, during and/or after step (a) is carried out; and by (c) optionally removing, drying and isolating in the form of a powder the salt-like, hydrophobic structured silicate produced during step (b). |
