Among others, dimethyl methyl phosphate (DMMP) was applied in flame retarding of polyurethane owing to its so much merit. However, the water-soluble property of DMMP restricted its application in textile fabric. The flame retarding system containing DMMP will be microencapsulated to form a novel flame retardant that could be used in textiles. We have studied the built–up effect of DMMP with some inorganic compounds to improve the afterflame and afterglow suppression in the flame retarding system. The experimental data indicated that inorganic compounds containing various non-metal elements P, N, B and metal ions Mg2+, Al3+, Ca2+, Zn2+, Cu2+, Mn4+ could be applied in flame retarding systems as additives to effectively suppress afterflame or afterglow.展开更多
