    • Sulfonated condensation products that are stable in storage and have increased thermal stability are based on aminoplastic formers having at least two amino groups or naphthalene and formaldehyde and, optionally include organic nitrogen bases which additionally contain, as nitrogenous formulation auxiliary agents, compounds of general formula (I) R1—NH—X—Y—R2, wherein R1 and R2 independently represent H, —CH3, —C2H5, —C3H7, —(CH2)n—CH2—; X═—CH2, CO, CS; Y═S, NH, —(CH2)m—; n=0 to 9; m=1 to 4; and/or compounds of general formula (II), wherein Z═—OCH3, —SO3—H, —SO3Na+, —NO2, —NH2, —NH—NH2, —CO2—Na+, —CHO. The mole ratio of aminoplastic formers: formaldehyde: sulfite: nitrogenous formulation auxiliary agents rangin from 1:1.9 to 6.0:1.0 to 2.0:0.01 to 1.5 and/or the mole ratio of naphthalene sulfonic acid: formaldehyde; nitrogenous formulation auxiliary agents equals 1:0.7 to 3.0:0.01 to 1.5. Method for preparing these condensation products of using them, e.g., as additives for inorganic binding agents and for hydraulically setting dry mixtures that contain inorganic binding agents are also disclosed.
    • 在储存中稳定并且具有增加的热稳定性的磺化缩合产物基于具有至少两个氨基或萘和甲醛的氨基成型剂,并且任选地包括另外含有作为含氮制剂助剂的有机氮碱,通式( I)R 1 -NH-XYR 2,其中R 1和R 2独立地表示H,-CH 3,-C 2 H 5,-C 3 H 7, - (CH 2)n -CH 2 - ; X = -CH 2,CO,CS; Y = S,NH, - (CH 2)m - ; n = 0〜9; m = 1〜4; 和/或通式(II)的化合物,其中Z = -OCH 3,-SO 3 -H,-SO 3 Na +,-NO 2,-NH 2,-NH-NH 2,-CO 2 -NO +,-CHO。 氨基甲酸甲酯:甲醛:亚硫酸盐:含氮配方助剂的摩尔比为1:1.9至6.0:1.0至2.0:0.01至1.5和/或萘磺酸:甲醛的摩尔比; 含氮制剂助剂为1:0.7至3.0:0.01至1.5。 还公开了制备这些使用它们的缩合产物的方法,例如作为无机粘合剂的添加剂和用于水凝固化含有无机粘合剂的干混合物的方法。
