| titleOfInvention | A kind of method for preparing cationic polyacrylamide emulsion by water dispersion polymerization |
| abstract | The invention discloses a method for preparing cationic polyacrylamide emulsion by water dispersion polymerization. In the preparation method, nonionic monomers, cationic monomers, dispersion stabilizers, some inorganic salts and auxiliary agents are dissolved in deionized water, stirred in a constant temperature water bath at 40-70° C. to form a homogeneous system, and nitrogen is passed to remove oxygen at the same time. The initiator, which accounts for 50 to 80% of the total mass of the initiator raw material, is continuously reacted for 3 to 6 hours, and then the remaining initiator is added, and then reacted, and the remaining inorganic salt is added, and the stirring is continued to obtain a cationic polyacrylamide emulsion; A novel redox initiator system uses graphene oxide as reducing agent and persulfate as oxidant to prepare cationic polyacrylamide emulsion by water dispersion polymerization. The emulsion prepared by the invention has the characteristics of instant solubility, high molecular weight, good fluidity and stability, hardly adding organic solvent in the polymerization process, green and non-toxic, and can absorb trace heavy metal ions and the like. |
