Title: AMMONIUM POLYPHOSPHATE BASED AND DIAMMONIUM PHOSPHATE BASED FIRE-RETARDANT COMPOSITIONS
Abstract:
An ammonium polyphosphate based fire-retardant composition comprises an ammonium polyphosphate or a diammonium phosphate, a suspending agent, a coloring agent, a surfactant, a thickening agent, and a corrosion inhibiting agent. The suspending agent may be a sheared clay. The sheared clay may be a sheared Attapulgite clay. The coloring agent may be iron oxide. The surfactant may be selected from the group of surfactants including sulfonates, carboxyl acids, carboxylates, carboxymethyl cellulose, and catechins. The surfactant may be an emulsifier. The thickening agent may be Xanthan gum with a weight average particle size diameter greater than 100 microns. The corrosion inhibiting agent may be potassium ferricyanide or potassium ferrocyanide.
