Preparation method of anti-clay type polycarboxylate superplasticizer
The invention discloses a preparation method of an anti-clay type polycarboxylate superplasticizer. The method is characterized in that: itaconic acid and diethylaminoethyl methacrylate are taken as the monomers, ammonium persulfate is adopted as the initiating agent, and mercaptopropionic acid is employed as the conditioning agent to carry out copolymerization in water so as to obtain the anti-clay type polycarboxylate superplasticizer. The preparation method provided by the invention has the characteristics of cheap raw materials, mild preparation condition and low cost, and the obtained polycarboxylate superplasticizer has a high water-reducing rate and also has good anti-clay property.
