【Abstract】 Flame-retardant mechanism of haloalkyl phosphate was discussed.Brominated phosphate(BP60) was selected as an additive flame retardant of semi-rigid integral-skin polyurethane foam(SRISPUF) and successefully added to the component of polyether.The samples with tight skin layer were prepared.The influences of different BP60 contents on horizontal flame retardency of SRISPUF were investigated.更多还原
