| titleOfInvention | A kind of hyperbranched polymer flocculant and preparation method thereof |
| abstract | The invention provides a hyperbranched polymer flocculant and a preparation method thereof, and relates to the technical field of sewage treatment. The method comprises: combining bis(2-hydroxyethyl)amino(trimethylol)methane with 2,4,6 ‑Trihydroxybenzoic acid is reacted to obtain hyperbranched intermediates; hyperbranched intermediates and halogenated olefins are subjected to quaternization reactions to obtain hyperbranched monomers; anionic monomers, cationic monomers, amide monomers, hyperbranched The monomer is added into deionized water, and a polymerization assistant is added under a nitrogen atmosphere to initiate a polymerization reaction to obtain a hyperbranched polymer flocculant. The hyperbranched polymer flocculant prepared by the invention has a hyperbranched three-dimensional network structure, and the end of the branched structure contains a large number of hydroxyl groups, has strong complexation ability with pollutants, large loading capacity, remarkable flocculation effect, and high clarity of the treatment liquid. |
