摘要
A series of waterborne polyurethane(WPU) emulsions,which were modified with organic phosphorus(P) of flame retardant,were synthesized by changing the amount of FRC-6.Polyether 210(N-210),isophorone diisocyanate(IPDI),[(bis(2hydroxyethyl) amino) methyl] diethyl(FRC-6) and(diethylene) glycol(EX),dimethylol propionic acid(DMPA),and 3-(2-aminoethyl) aminopropyl methyl(dimethoxy) silane(KH-602) were used as the basic monomer,chain extender,hydrophilic chain extender(and a kind) of chain extenders which was added after emulsifing,respectively.The results showed that both thermal decomposition temperature and heat release rate of polyurethane(PU) were reduced,while the flame retardant of PU was improved greatly with the increase of FRC-6.The oxygen index was 28% and vertical burn test indicated that the flame retardancy of polyurethane had reached UL-94V-2,when the P content within FRC-6 was 2.31% in the prepolymer.
