Part, equal infusion 0.5-2 parts and water 3-4 parts；Wherein, the composite catalyst is the compound of amines catalyst and tin catalyst.
This is by synergistic effect caused by the proportion of adjusting formula and the different proportion of each based flame retardant, to improve sponge product
Flame retardant property and reduce influence of the fire retardant to the physical properties of sponge product, but still to solve be used for a long time
Cheng Zhong, the migration of fire retardant, precipitation, the last properties of product of flexibel polyurethane bubble have the problem of change.
Under conditions of not interfering with the mechanical performance of sponge product, the exploitation for having the fire proofing of the functions such as anti-mite is ground
Study carefully flame-retardant sponge and need most and one of solves the problems, such as.
