摘　　要：以剑麻纤维废弃物麻糠和麻头为基本原料,以氢氧化钠、脲、水为溶剂体系制备了纤维素溶液,以Na2SO4为成孔剂,利用纤维素易于再生的特性制备了纤维素海绵。研究了氢氧化钠、脲的低温溶液对纤维素的溶解能力以及成孔剂的用量对海绵的吸水性及力学性能的影响。结果表明,制备剑麻纤维素海绵的最佳条件为每100mL溶液中NaOH和脲的质量分别为12g和8g,纤维素的质量分数为4.5%左右,成孔剂的用量为35g左右。The bran and hemp sisal hemp waste head as the basic raw material, sodium hydroxide, urea, water as solvent system prepared cellulose solution,to the Na2SO4 as pore forming agent, using easily regenerated cellulose characteristics, prepared cellulose sponge. Study of NaOH, urea solution at low temperature and the solubility of ce- llulose amount of pore-{orming agent absorbent sponge and mechanical properties. The results show that the optimal preparation conditions for sisal cellulose sponges for each 100mL solution of NaOH and urea, respectively 12g and the quality of 8g; cellulose mass fraction of around 4. 5% the amount of pore-forming agent is about 35g.
