| abstract |
The present invention is a method for producing a porous material, the step of preparing a mixture (I), wherein the mixture (I) is a composition (A) as a component (ai) Polymeric polyfunctional isocyanate, comprising at least an isocyanate composition (A *) comprising monomer polyfunctional isocyanate as component (aii) and at least one catalyst as component (ac), substantially comprising an aromatic amine A step containing the composition (A) and the solvent (B) not contained in the step, a step of reacting the components in the composition (A) to obtain an organic gel, and a step of drying the gel obtained in the step b) At least. The invention further relates to a porous material that can be obtained in this way and to a method of using the porous material as a thermal insulation material and in a vacuum insulation panel. |
