摘要：A flame retardant composition and process which is particularly useful forrebonded foam products. The composition of the present invention includes a solidcomponent of magnesium sulfate, boric acid, decabromodiphenylethylene oxide (DECA)and antimony trioxide and a liquid component of halogenated phosphorous. The presentinvention is based upon the discovery of the synergism between boric acid and DECA. Theprocess, according to the present invention, includes the steps of forming a dispersion ofthe solid portion of the flame retardant composition along with a small amount of waterbased adhesive to a mass of foam chips. The treated chips are then dried to permithandling and storage. The dried foam chips subsequently are mixed with a conventionalurethane prepolymer binder and the liquid halogenated phosphorous flame retardantcompound. After mixing the foam mass is transferred to molds and steamed to allow thebinder to cure. Rebonded foam manufactured by this process displays excellent physicalproperties while, at the same time, exhibits a Flame Spread Index I.sub.s value of less thanabout 25.
