摘要
将稻壳、液化剂和催化剂制备生物质液化多元醇,并以此生物质液化多元醇、辛酸亚锡、三乙烯二胺、有机硅匀泡剂、去离子水和多亚甲基多苯基异氰酸酯(PAPI)等为原料成功制备了生物质基聚氨酯泡沫(BPUF)。研究了PAPI用量对BPUF的密度、拉伸强度、吸油性能的影响。结果表明:随着PAPI用量的提高,BPUF的密度减小,拉伸强度提高,BPUF的吸油倍率增加,对于3种不同的油品:苯、甲苯和柴油,柴油最大吸油量最低,苯最大吸油量最高,达到18g/g。
The biomass polyol was prepared first by rice husk, liquefied agent and catalyst as raw materials, then the biomass polyurethane foams（BPUF） used for oil absorption in the rivers, lakes, seas et al were prepared by used the bio- mass polyol,stannous octoate, triethylene diamine, organosilicon foam stabilizer, deionized water and polymethylene poly- phenyl isocyanate（PAPI） as raw materials. The effects of the dosage of PAPI on the properties of BPUF such as density, tensile strength , oil absorbency were studied. The results showed that the density of BPUF was decreased while the tensile strength was increased with increased dosage of PAPI, and the oil absorption ratio also was increased. The diesel maximum absorption was the lowest in three different oil. Benzene, toluene and diesel, while benzene maximum absorption was the highest,which reached 18 g/g.
