The present invention relates to a process for producing flame-retardant porous materials comprising the following steps:
(a) reacting at least one polyfunctional isocyanate (a1) and at least one polyfunctional aromatic amine (a2) in an organic solvent optionally in the presence of water as component (a3) and optionally in the presence of at least one catalyst (a5); and then
(b) removing the organic solvent to obtain the organic porous material,
where step (a) is carried out in the presence of at least one organic flame retardant as component (a4), where this flame retardant is soluble in the solvent.
The invention further relates to the porous materials thus obtainable, and also to the use of the porous materials for thermal insulation.
本发明涉及一种生产阻燃多孔材料的工艺,包括以下步骤:
(a) 使至少一种多官能团
异氰酸酯(a1)和至少一种多官能团芳香胺(a2)在有机 溶剂中反应,可选择有
水作为组分(a3)存在,也可选择有至少一种催化剂 (a5)存在;然后
(b) 去除有机溶剂,得到有机多孔材料、
其中,步骤(a)是在至少一种有机阻燃剂作为组分(a4)存在的情况下进行的,这种阻燃剂可溶于溶剂。
本发明还涉及由此获得的多孔材料,以及多孔材料在隔热方面的用途。
