摘　　要：对脂肪族与木质素磺酸钠减水剂接枝共聚产物的性能进行了研究,并将共聚产物与脂肪族减水剂本身及脂肪族减水剂与木质素磺酸钠减水剂复配产品的性能进行了对比。结果表明,接枝共聚物在减水率与和易性方面都优于复配产品,而且掺接枝共聚减水剂的混凝土不易泌水、离析。This paper studies the acyclic water reducer and sodium lignosulfonate water reducing agent copolymerization prod- uct＇s properties,and these properties are compared to the acyclic water reducer＇s properties and the acyclic water reducer compound with the sodium lignosulfonate water reducer product＇s properties. The result shows that,the graft copolymerization product is superi- or to the compound product in water reducing rate and workability,moreover, the concrete that compound with the graft copolymer- ization product is less able to become segregating and bleeding.
