The disclosure relates to compositions for imparting flame retardant properties to various substrates including cellulosic materials, such as paper, cotton and wood, and plastics, such as fabrics made from synthetic polymeric fibers. Aqueous based compositions of the invention particularly suited to application to cellulosic substrates are multi-component compositions comprising a surfactant, a combination of ammonium iodide, ammonium bromide, ammonium monophosphate, ammonium sulphate, borax, boric acid, sodium silicate and a moistening agent. Another aqueous- based system especially adapted to the treatment of fabrics made from a combination of cellulosic and synthetic fibers comprises a surfactant, hydroxy propyl methyl cellulosic, tripropylene glycol, sodium metaborate, chlorinated paraffin hydrocarbon, ammonium diphosphate, ammonium lauryl sulphate, ammonium iodide and other ingredients. An aqueous-based composition comprising an acrylic polymer emulsion base is also disclosed as a flame retardant paint or enamel. Finally, a flame retardant composition having a polyvinyl chloride (PVC) paste base is described for use in providing polymeric materials with flame retardant properties. |
