摘　　要：以聚醚多元醇和甲苯二异氰酸酯为原料,合成了两种孔径大小和开孔率不同的软质聚氨酯泡沫塑料(PUF),研究了它们对3号喷气燃料、甲苯和军用柴油的吸油倍率。结果表明,PUF的孔径大小和开孔率直接影响其吸油性能,孔径越大,开孔率越高,对油品的吸油倍率越大;同时,油品分子的大小也会影响其吸油性能,甲苯分子最小,其吸油倍率最高,3号喷气燃料中因含有较多的较大分子的环烷烃,其吸油倍率最小。Using polyether polyol and toluene diisocyanate （TDI）, two kinds of flexible polyurethane foam with different pore size and the cell-opening rate were synthesized, and their oil absorption ratio for No.3 jet fuel, toluene and military diesel were also studied. The results showed that the pore size and cell-opening rate of PUF directly affect the oil absorption properties. The oil absorption rate was increased when the pore size and the cell opening rate increased. The size of the oil molecules could also affect its oil absorption properties. Toluene had the smallest molecule, and its oil absorption rate was the highest, while the molecules of No.3 jet fuel was large and its oil absorption rate was the lowest because of containing more cyclane.
