摘要： A flame retardant composition and process which is particularly useful for rebonded foam products. The composition of the present invention includes a solid component of magnesium sulfate, boric acid, decabromodiphenylethylene oxide (DECA) and antimony trioxide and a liquid component of halogenated phosphorous. The present invention is based upon the discovery of the synergism between boric acid and DECA. The process, according to the present invention, includes the steps of forming a dispersion of the solid portion of the flame retardant composition along with a small amount of water based adhesive to a mass of foam chips. The treated chips are then dried to permit handling and storage. The dried foam chips subsequently are mixed with a conventional urethane prepolymer binder and the liquid halogenated phosphorous flame retardant compound. After mixing the foam mass is transferred to molds and steamed to allow the binder to cure. Rebonded foam manufactured by this process displays excellent physical properties while, at the same time, exhibits a Flame Spread Index I.sub.s value of less than about 25.

摘要翻译： 阻燃组合物和方法，其特别适用于重新粘合的泡沫产品。 本发明的组合物包括硫酸镁，硼酸，十溴二苯醚环氧乙烷（DECA）和三氧化锑的固体组分和卤化磷的液体组分。 本发明基于硼酸与DECA之间的协同作用的发现。 根据本发明的方法包括以下步骤：将阻燃剂组合物的固体部分与少量的水基粘合剂一起分散在一块泡沫芯片上。 然后将经处理的碎片干燥以允许处理和储存。 随后将干燥的泡沫碎片与常规的氨基甲酸酯预聚物粘合剂和液体卤化磷阻燃化合物混合。 混合后，将泡沫块转移到模具中并蒸汽，以使粘合剂固化。 通过该方法制造的再结合泡沫显示出优异的物理性质，同时表现出小于约25的火焰蔓延指数Is值。
