摘　　要：通过对固化后PAE以及本色湿强废纸在蒸煮中的行为表现进行探讨,研究了树脂本色湿强废纸的再制浆工艺。研究结果显示:利用蒸煮法通过改变纤维表面残留木素状态,能有效对利用PAE树脂增湿强处理的本色湿强废纸进行再制浆;在温度160℃,AQ用量0.05%,液比1∶6,保温30min,用碱量1%的情况下,再制浆后无残渣;不使用碱进行蒸煮时,延长保温时间有利于减少再制浆后残渣量。The performance of cooking for the solidified PAE and the unbleached waste paper were discussed. The cooking schedule for the unbleached waste paper was studied. It was showed that, the distribution of the fiber surface lignin was changed by the cooking. It can be efficiency to repulping the unbleached waste paper used PAE. Under the conditions：temperature 160℃,AQ usage 0.05%, liquor ratio 1：6, time at maximum 30min, alkali usage reached 1%, the waste paper can be completely repulped. When not used the alkali on cooking, the railings can be reduced by prolonged the time at maximum.
