摘　　要：以聚醚多元醇、亲油性二元醇、三乙烯二胺、辛酸亚锡、有机硅匀泡剂、去离子水、可膨胀石墨(EG)、三(2-氯乙基)磷酸酯(TCEP)、甲苯二异氰酸酯(TDI)为原料制备了阻燃吸油型聚氨酯泡沫,研究了EG用量对该阻燃型聚氨酯泡沫的泡孔结构、吸油性能和阻燃性能的影响。结果表明:随着EG用量的增加,聚氨酯泡沫的吸油性能呈下降趋势;EG和TCEP并用可以产生协同阻燃效应,聚氨酯泡沫的极限氧指数最高可达36%。A series of flame retardant oil-absorbing polyurethane foams（PUF） were prepared by using polyether polyols, lipophilic dihydric alcohol, triethylene diamine, stannous octoate, organosilicon foam stabilizer, deionized water, expandable graphite（EG）, tris（2-chloroethyl） phosphate（TECP） and toluene diisocyanate（TDI） as raw material. The effects of EG content on tensile strength, oil absorption and flame resistant property of the PUF were investigated. The results show that the oil absorption ratio of the PUF decreases by increasing the content of EG. The limited oxygen index of the PUF reaches 36% owe to EG and TCEP producing flame retardant synergistic effect.
