Preparation method for modified starch comb-shaped copolymer
The invention discloses a preparation method for a modified starch comb-shaped copolymer. The preparation method comprises: sulfonated starch is prepared, an esterification reaction with maleic anhydride is carried out, esterified starch is prepared, finally, a copolymerization reaction is carried out and a modified starch comb-shaped copolymer product is obtained. The prepared comb-shaped copolymer forms strong steric hindrance on outer surfaces of cement particles, is beneficial for dispersion effects, and has a high water-reducing rate and shrinkage ratio.
