Abstract
A flame retardant or fire retardant preparation can be employed with fibrous material containing either cellulosic fibers, non-absorbent fibers, or blends thereof. The preparation is formed of an aqueous solution of ammonium sulfate, a metasilicate salt serving as a binder, and ammonium phosphate (MAP or DAP). An ultraviolet inhibitor is preferably included in the solution. A wetting agent promotes penetration of the solution into cellulosic fibers. An ultraviolet fluorescent agent permits non-destructive testing of articles after treatment.
Claims16
A flame-retardant or fire-retardant preparation that consists essentially of an aqueous solution of ammonium sulfate, a metasilicate salt serving as a binder, ammonium phosphate, and an effective amount of a wetting agent which promotes penetration of the aqueous solution into fibrous material.
A flame-retardant or fire-retardant preparation that consists essentially of an aqueous solution of ammonium sulfate, a metasilicate salt serving as a binder, ammonium phosphate, and an effective amount of a fluorescent agent which is invisible under normal visible light but clearly visible under ultraviolet illumination.
A flame-retardant or fire-retardant preparation that consists essentially of an aqueous solution of ammonium sulfate, a metasilicate salt serving as a binder, ammonium phosphate, an ultraviolet inhibitor, and an effective amount of a wetting agent which promotes penetration of the aqueous solution into fibrous material.
A flame-retardant or fire-retardant preparation that consists essentially of an aqueous solution of ammonium sulfate, a metasilicate salt serving as a binder, ammonium phosphate, an ultraviolet inhibitor, an effective amount of a wetting agent which promotes penetration of the aqueous solution into fibrous materials, and an effective amount of a fluorescent agent which is invisible under normal visible light but is clearly visible under ultraviolet illumination.
A flame-retardant or fire-retardant preparation that consists essentially of an aqueous solution of ammonium sulfate, a metasilicate salt serving as a binder, ammonium phosphate, an ultraviolet inhibitor, and an effective amount of a fluorescent agent which is invisible under normal visible light but clearly visible under ultraviolet illumination.
A flame-retardant or fire-retardant preparation that comprises an aqueous solution of a water soluble inorganic salt, a water-soluble binder agent for bonding the inorganic salt to cellulosic fibers, and an effective amount of an ultraviolet fluorescent agent which is invisible under normal visible light, but clearly visible under ultraviolet illumination.
