| titleOfInvention | A kind of preparation method of cationic flocculant |
| abstract | The invention discloses a kind of preparation methods of cationic flocculant, the described method comprises the following steps：(1) following reactant is mixed：Monomer, water, organic solvent, cosolvent and complexing agent, the monomer includes monomer A and monomer B, the monomer A are at least one of dimethyl diallyl ammonium chloride, dimethylaminoethyl methacrylate chloromethanes salt, and the monomer B is acrylamide；(2) 35~40 DEG C are warming up to, under nitrogen or inert gas shielding, initiator A is added, reacts 1~3 hour, unsaturated carboxylic acid and initiator B is added, reacts 2~3 hours；(3) 60~70 DEG C are warming up to, water is added, is reacted 1~6 hour.Preparation method of the present invention is simple for process, efficient；The cationic flocculant viscosity that is prepared is higher, cationic degree and theoretical cationic degree are close, has the effect of in terms of the processing of low turbidity water, sludge dewatering, animal waste etc. more significant. |
