The invention relates to a fatty diamide comprising or consisting of a reaction product obtained from:
a) at least one cycloaliphatic diamine comprising a ring of 6 carbon atoms,
b) a fatty hydroxy acid chosen from 12-hydroxystearic acid (12-HSA), 9-hydroxystearic acid (9-HSA), 10-hydroxystearic acid (10-HSA), 14-hydroxyeicosanoic acid (14-HEA) or binary or ternary or quaternary mixtures thereof,
c) at least a second diamine chosen from linear aliphatic C2 to C12 primary diamines,
d) optionally, at least one monoacid chosen from saturated and non-hydroxylated linear C6 to C16 carboxylic acids,
e) optionally, at least a third primary diamine different from c) chosen from linear aliphatic C2 to C12 diamines.
f) at least one aromatic amine chosen from xylylenediamines, said aromatic diamine possibly being partially or totally replaced with said diamine a).
The invention also covers the use of this diamide as an organogelling agent, in particular as a rheology additive, for coating, glue, adhesive or cosmetic, stripping, molding, mastic or sealing compositions.
本发明涉及一种脂肪二酰胺,它包含或由以下物质的反应产物组成:

b) 脂肪羟基酸,选自 12-羟基硬脂酸 (12-HSA)、9-羟基硬脂酸 (9-HSA)、10-羟基硬脂酸 (10-HSA)、14-羟基二十烷酸 (14-HEA) 或它们的二元、三元或四元混合物、
c) 至少第二种二胺,选自线性脂肪族 C2 至 C12 伯二胺、
d) 可选的至少一种单酸,选自饱和且非羟化的线性 C6 至 C16 羧酸、
e) 可选地,至少一种不同于 c) 的第三种伯二胺,选自线性脂肪族 C2 至 C12 二胺。
f) 至少一种芳香族胺,选自二元乙二胺,所述芳香族二胺可能部分或全部被所述二元胺 a) 取代。
本发明还包括将这种二酰胺用作有机胶凝剂,特别是作为流变添加剂,用于涂料、胶水、粘合剂或化妆品、剥离、成型、胶泥或密封组合物。
