摘要
选用改性单体对传统氨基磺酸盐系高效减水剂进行改性,以提高减水剂的保水性、减小泌水率。主要介绍了氨基磺酸盐系高性能减水剂的合成过程,通过对反应体系的单体摩尔比、酸碱度、反应温度、反应时间等工艺参数的控制,合成了具有分散性好、泌水率小、流动度经时损失小的氨基磺酸盐系高性能减水剂。
Conventional sulphamate series superplasticizer is modified by modified monomer so as to improve the water retention and to reduce the bleeding rate of water reducing agent. It mainly introduced the synthetic process of sulphamate series superplasticizer. The sulphamate series superplasticizer can be synthesized by means of controlling process parameters such as monomer tool ratio, pH value, reaction temperature and reaction time, which has high dispersibility, low bleeding rate and less fluidity loss.
