| titleOfInvention | Structure flame retardant Rosin-based Polyol and its preparation method and application for hard polyurethane foams |
| abstract | Structure flame retardant Rosin-based Polyol and its preparation method and application for hard polyurethane foams, by rosin through obtaining fire-retardant rosin derivative monomer with diethyl phosphate open loop again after epoxidation reaction, structure flame retardant Rosin-based Polyol is made in last and ethylene oxide or propylene oxide ring-opening polymerization.Flame-retardant phosphate esters group is introduced into rosin structure using epoxy ring opening reaction, structure flame retardant Rosin-based Polyol is synthesized, fire-retardant cost is reduced, contains regulatable ester bond and ehter bond in polyol structure and commercial polyesters, polyether polyol compatibility is preferable；And reactivity is higher, phosphorus content is up to 8.0%；With the flame retarded polyurethane-foam that it is prepared, oxygen index (OI) can reach 24 ~ 27%, has the advantages that product No drip type when burning, holding shape, smoke density is small, is with a wide range of applications in some special occasions such as building heat preservation, pipeline transportation. |
