More Information
Summary:The present invention provides a soft (dispersant) and hard (nano clay) composite dispersant (water reducing agent), which can effectively control the gathering behavior of cement particles. The present invention mainly uses the styrene-co-maleic anhydride as the main chain and is grafted with methyl-polyethylene glycol. Further, the montmorillonite after being modified is treated as nano dispersant, such that the methyl-polyethylene glycol is the high polymer hydrophilic group and the montmorillonite is the lipophilic group. Therefore, the gathering behavior of electrostatic interaction can be efficiently avoided, and the intervals between cement particles can be raised and, at the same time, the fluidity and working property can be improved.
