| 摘 要： | 采用连续浸提和半纤维素酶处理方法,从工业碱木质素（M1）中脱去糖类物质后得到纯度不等的木质素样品M2和M3,同时进行木质素脲醛树脂的制备。结果表明,木质素经过抽提和酶处理后得到木质素M3其纯度为97％,当其添加量为甲醛和尿素总量的35％时,合成的胶粘剂的粘结性能优良,具有资源环保意义。

| Abstract: | Alkaline lignin were removed the sugar by the continuous immersion and extraction processes and then treated with xylanase and got a kind of lignin which content 97 % "purified lignin".The results indicated that when the purified lignin were 35 % total weight of formaldehyde and urea,the performance of adhesive was satisfactory and it has great meaning of resource environmental protection. |
