| 摘要 |
The present invention relates to a method for producing flame-proofed porous polyurea-based 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 subsequently (b) removing the organic solvent so as to obtain the organic porous material, wherein step (a) is carried out in the presence of at least one organic flame-proofing agent as component (a4), which is soluble in the solvent. The invention relates to the porous materials which can thus be obtained and to the use of the porous materials for thermal insulation. |
