FLAME RETARDANT FOR CELLULOSE BASED MATERIALS

摘要

Cellulose based insulation materials are treated with phosphate compounds to provide flame retardant properties and reduce or eliminate the propensity of the cellulose based materials to ignite and propagate flame or smolder. The phosphate compounds may be blended with the cellulose based material in a dry process. Alternatively, the phosphate compound may be dissolved or dispersed in water or other solvent and sprayed on the cellulosic material. The cellulose material is then dried prior to use. The treated cellulose materials may be further conditioned prior to use by heating to between 30°C and 100°C for 12 to 48 hours.
