MATERIALE DA COSTRUZIONE INIBITORE DI FIAMMA E PROCEDIMENTO PER LA SUA PREPARAZIONE |
摘要 |
<p>The building material of the invention, which is in a disintegrated fluffy form and suitable for shaping into a board for walls and ceilings or as a blow-on or blow-in insulating material having excellent performance as heat and sound insulation, comprises essentially a disintegrated organic fibrous material, e.g. disintegrated scrapped paper and gel-like aluminum hydroxide uniformly blended with the fibrous material together with a flame retardant agent which is preferably an inorganic phosphate such as sodium phosphate and disodium hydrogen phosphate and, optionally, with a waterproofing agent. The building material is prepared by first mixing the organic fibrous material with an aqueous solution of the phosphate and then with an aluminum hydroxide sludge obtained as a noxious industrial waste in aluminum-processing industries employing surface anodization followed by drying and disintegration.</p> |
