Dispergiermittel für anorganische Partikel
Dispersing agent for inorganic particles, preferably inorganic hydraulic binders, comprises (i) at least one, preferably 1 or 2 triazine structural units, preferably 1,3,5-triazine structural units, (ii) at least one, preferably 1 polyalkylene glycol structural unit, and (iii) at least two, preferably 2-4 phosphoric acid ester structural units. Independent claims are also included for: (1) preparing the dispersing agent for inorganic particles using (a) at least one trihalo-triazine, preferably 2,4,6-trihalo-1,3,5-triazine, preferably 2,4,6-trichloro-1,3,5-triazine, (b) at least one compound, which is reactive with the halo substituents of the trihalo-triazine, and comprises at least one polyalkylene glycol unit, preferably nucleophilic compound, which comprises only one nucleophilic group that is reactive with the halo substituents of the trihalo-triazine, (c1) at least one compound, which comprises primary and/or secondary amino alcohols, preferably primary and/or secondary alkanolamines having greater than one hydroxy groups and only one primary or secondary amino group, preferably diethanolamine, and (c2) at least one phosphating agent for phosphating hydroxy groups, preferably phosphoric acid, phosphorus pentoxide, phosphorus pentachloride, phosphorus oxychloride and/or polyphosphoric acid (preferred), or using the reactants (a), (b) and (d) at least one primary and/or secondary aminoalcohol, which is phosphated at the hydroxy group, preferably phosphated primary and/or secondary alkanolamine having greater than one phosphated hydroxy group and only one primary or secondary amino group, preferably diphosphated and/or monophosphated diethanolamine; and (2) a building material mixture comprising at least one above dispersing agent and at least one inorganic binder, which comprises Portland cement, alpha -calcium sulfate hemihydrate, beta -calcium sulfate hemihydrate, calcium sulfate in the form of anhydrite, slag sand, fly ash, silica fume, blast furnace slag, natural pozzolan and/or burnt oil shale, preferably Portland cement in an amount of greater than 40 wt.%, based on the total amount of inorganic binder.
