Use of naphthalene sulfonic acid polycondensates as plasticizers in building compositions and building compositions
The naphthalene sulfonic acid polycondensate is used as a plasticizer in a building composition comprising sand and at least one cementitious binder. The naphthalenesulfonic acid polycondensate is obtainable by the condensation reaction of i) naphthalenesulfonic acid, ii) an alkoxylated hydroxyaryl compound having a polyoxyalkylene chain having 3 to 130 oxyalkylene units, and iii) formaldehyde, the weight ratio of i) to ii) being 95: 5 to 60: 40, preferably 95: 5 to 75: 25, more preferably 95: 5 to 85: 15, the sand having a methylene blue value according to DIN EN 933-9 of at least 10 g/kg. The naphthalene sulfonic acid polycondensate is insensitive to clay to a great extent, and the dispersity of the naphthalene sulfonic acid polycondensate is irrelevant to the quality of sand.
萘磺酸缩聚物在包含砂和至少一种水泥基粘合剂的建筑组合物中用作增塑剂。萘磺酸缩聚物可通过以下组分的缩合反应获得：i)萘磺酸、ii)具有含3至130个氧基亚烷基单元的聚氧基亚烷基链的烷氧基化的羟基芳基化合物和iii)甲醛，i)与ii)的重量比为95:5至60:40、优选为95:5至75:25，更优选为95:5至85:15，其中砂具有根据DIN EN 933-9的至少10g/kg的亚甲基蓝值。萘磺酸缩聚物在很大程度上对粘土不敏感，并且其分散性与砂的质量无关。
