| titleOfInvention | The preparation method for the cation polyacrylamide emulsion that viscosity is low, stability is high |
| abstract | A kind of preparation method for the cation polyacrylamide emulsion that the present invention relates to viscositys is low, stability is high, the following steps are included: being separately added into polyethylene glycol, acrylamide, cationic monomer acrylamido (2- hydroxyl) hydroxypropyltrimonium chloride, dimethyl diallyl ammonium chloride and auxiliary agent β-dimethylaminopropionitrile, urea in (1) deionized water, stirring and dissolving is uniformly mixed；It (2) is 2~5 with the pH value of solution system in dust technology regulating step (1)；(3) dissolved oxygen being passed through in high pure nitrogen expeling solution, is added initiator ammonium persulfate, formaldehyde Sodium Thiosulfate and V-50, is stirred to react 2h~5h at 30 DEG C~50 DEG C, obtains polymer emulsion product.The beneficial effects of the present invention are:, by aqueous two-phase dispersion copolymerization method, the cation polyacrylamide emulsion product that production cost is low, viscosity is low, particle diameter distribution is uniform, stability is high is prepared using novel cation monomer. |
