摘要
分析了脂肪族磺酸盐减水剂的合成机理,概述了脂肪族磺酸盐减水剂的合成方法及其性能。提出今后应充分重视引入酸性基团化合物对脂肪族缩合物进行接枝改良处理的研究,加大对微波和无热源法合成脂肪族减水剂工艺和性能的研究,并尝试研究用苯乙酮作为原料生产脂肪族减水剂。并就SAF型脂肪族减水剂的加料顺序、磺化剂种类、溶液pH值对减水剂减水率的影响进行了对比试验。
Synthetic mechanism of sulfonated aliphatic series water reducer is analyzed, and the synthetic method and performance is summarized. It is suggested that we should pay attention to the research of introducing acid groups compound to graft and improving aliphatic series condensation compound in future, microwave method and py- rogen free method to compound aliphatie series should be increased, and try to use acetophenone as the material to produce the aliphatic series water-reducer. Effect of water reducing ratio of SAF sulfonated aliphatic series water re- ducer by arranging the sequence of adding material, the type of sulfonating agent and the pH value of solution were contrasted.
