Surface treatment of mineral substance e.g. for private and public traffic area, highway, building exterior or safety floor uses 2-stage treatment with substances forming silicic acid in pores and on surface and added mineral particles

In surface treatment system for mineral substances and substances with mineral additives comprising (a) pretreatment and (b) second treatment substances and (c) pore fillers, added to or strewn on (a) and/or (b), (a) is an alcoholic-aqueous and/or aqueous solution of modified silicic acid and silicates, including colloidal silicic acid as dispersion colloid; (b) a mixture of alcoholic aqueous solution, modified silicic acid and modified polymeric silicic acid and/or solvent-free polymeric silicic acid; and (c) finely disperse minerals of particle size 5 mu m to 1.25 mm. In surface treatment system for mineral substances and substances with mineral additives comprising (a) pretreatment and (b) second treatment substances and (c) pore fillers, the components are: (a) an alcoholic-aqueous and/or aqueous solution mixture of modified silicic acid and silicates, consisting of 1-50% colloidal silicic acid as dispersion colloid component (I), 0-80% silicic ester as mono- and/or polysilicic ester, 0-90% potassium or sodium methylsiliconate, 0-90% alkali silicate and water and treated with 0.01-80% alcohol (preferably ethanol), 0-22% carboxymethylcellulose and/or 0-35% unsaturated fatty acid or ester component (II) and 0-35% organic and/or inorganic pigment, fluorescent or signal pigment component (III); (b) a mixture of alcoholic-aqueous solution, modified silicic acid and modified polymeric silicic acid and/or solvent-free polymeric silicic acid, consisting of 1-49% (I), 0.5-80% alkylalkoxysilane, treated with 0-80% alcohol, and charged with 0.1-35% (II), 0-35% (III) and/or 0-25% dissolved organic polymers, preferably polyurethanes and/or polymethacrylates, and water, together with 0-3.5% emulsifier used to prepare the emulsion; and (c) finely disperse minerals of particle size 5 mu m to 1.25 mm, which preferably consist of silicates, limestone, dolomite, basalt, kieselguhr, borosilicate, serpentine fines, rhyolite fines, amphibolite fines or rock fines containing nepheline, e.g. phonolite, which have over 5% pores and a structural pore diameter of over 20.0 mu m and are added to or strewn on (a) and/or (b). An independent claim is included for a process for surface treatment of mineral substances and substances with mineral additives by means of the surface treatment system.
