| titleOfInvention | Hard polyurethane foams preparation method |
| abstract | Hard polyurethane foams preparation method of the present invention is related to polyurethane industrial field, and in particular to hard polyurethane foams preparation method, comprises the following steps：The preparation of the methyl imidazolium tetrafluoroborate of 1 butyl of ionic liquid 3, by l methylimidazoles, n-bromide butane and potassium tetrafluoroborate mixing are added in 100mL flasks, stirring, 3 3.5h of the lower reaction of 80 degree of constant temperature, it is cooled to room temperature, with dilution in acetonitrile, KBr precipitation filtering, filtrate moves to Rotary Evaporators, pressurization removes acetonitrile, and is vacuum dried 8h under 80 85 degree；The preparation of the methylimidazole hexafluorophosphate of 1 butyl of ionic liquid 3; under nitrogen protection; n-bromide butane is added drop-wise in 1 methylimidazole; stirring; the present invention utilizes the high thermal stability of ionic liquid; the methyl imidazolium tetrafluoroborate of 1 butyl of ionic liquid 3 and the methylimidazole hexafluorophosphate of 1 butyl 3 are prepared for, are applied in hard polyurethane foam as fire retardant.The defect that flame retardant volatility is big, heat resistance is not relatively high of seeing not only is overcome, the big shortcoming of halogenated flame retardant smoke amount is also overcomed. |
