Title (EN) FLAME RETARDANT IMPREGNATION SOLUTION AND THE USE OF THE SOLUTION
(FR) SOLUTION IGNIFUGE D'IMPREGNATION ET SON UTILISATION
Abstract:
(EN) A fireproofing solution and a method for obtaining fireproofed products using the fireproofing solution is described. In a preferred embodiment, the fireproofing solution comprises magnesium chloride and magnesium oxide, which are solubilized with an organic acid or an anhydride. The fireproofing solution can be incorporated in a porous material to render the entire material flame retardant.
(FR) Solution ignifuge et procédé de protection de produits contre le feu au moyen de la solution ignifuge. Dans un mode préférentiel de réalisation, la solution ignifuge comprend du chlorure de magnésium et de l'oxyde de magnésium solubilisés dans un acide organique ou un anhydride. On peut incorporer la solution ignifuge à un matériau poreux afin d'ignifuger tout le matériau.
