ABSTRACT:
High intensity yellow smoke and flame flare compositions are manufactured a procedure which closely parallels that of solid rocket propellants. These compositions use similar ingredients to those used in solid rocket propellants. These compositions are castable whereas conventional flares consist of pressed flare charges. Both colored flame and smoke are produced from the same composition. A liquid curable binder composition is selected from triethylene glycol succinate or carboxyl-terminated polybutadiene crosslinked with O,NN-tris(2,3-epoxypropyl)-4-aminophenol, and hydroxyl-terminated polybutadiene crosslinked with isophorone diisocyanate. The color producing ingredient is a first inorganic salt of lead iodide which can be further enhanced by an additive of a reactive source of iodine selected from iodine pentoxide and iodoform. A second inorganic salt is selected from inorganic oxidizing salts consisting of potassium perchlorate and amononium perchlorate. An optional additive of a magnesium metal is used where a good flame of yellow color is required. A large yellow-colored cloud produced from specific compositions is due to the condensation of the inorganic oxides and halides which produce submicron combustion particulates which do not undergo settling, or sedimentation. Their high specific surface area functions to enhance the color and to increase the size of the flare cloud.
