摘　　要：从造纸制浆废液中回收的木质素磺酸盐,价格低廉,来源广泛,又是一种天然的可再生资源,无疑是开发高效减水剂的理想原料,通过化学改性方法,可拓宽木质素的应用范围,并提高其附加值。主要探讨木质素的结构特点、化学反应性能和改性方法。结合制浆方法和原料种类,对制备改性减水剂的合理工艺进行分析总结,为绿色产业的发展和造纸废液治理做出贡献。Lignosulfonate features for lower cost, wider sources, and coming from recovery of pulping papermaking waste water.And it is ideal raw materials of natural regenerated resources in developing superplasticizer.The chemical modification broadened the application field of lignin and increased its economic value.The paper introduced structural characters, performance of chemical reaction, and modification methods in the field of lignin.Analysis and synthesis of rational preparation process of modified water reducers was reviewed combining pulping ways and sorts of making paper raw materials.Thus made developing green manufacturing industry and great contribution of harnessing papermaking waste water.
