摘　　要：我国利用废旧书刊纸脱墨,存在脱墨不净,白度不够,墨点较多等问题。本文报道了对现有脱墨剂配方的筛选,加入AEO表面活性剂,并改进工艺条件:NaOH质量分数2%,Na2SiO3质量分数3%,H2O2质量分数1%,AEO-10质量分数0.2%,AEO-35质量分数0.2%,十二烷基苯磺酸钠质量分数0.4%,熟化时间65 min,熟化温度55℃。Deinking papers generally used in our country are defected in unclear, whiteness insufficient, and over-dotted. This paper reports the improvement of domestic deinking prescriptions by adding surface active agent AEO and modifying the technology conditions as follows： NaOH, 2%, Na2 SiO3, 3%, H2O2,1%, AEO10,0.2%, AEO-35,0.2%, LSA,0.4%. Curing time 60, minutes, Curing temperature, 55 ℃.
