摘要
The present invention relates to a method for preparing a water-in-oil (W/O) type emulsion coagulant which comprises: a first step of preparing a first solution by dissolving a compound containing a nonionic water-soluble monomer and a cross linker in deionized water; a second step of preparing a second solution by dissolving dimethyl aminoethyl acrylate (DMAEA) which is a cationic monomer and a water-soluble monomer in the first solution; and a third step of injecting cationic water-dispersible polyacrylamide copolymer particles after injecting the second solution into an oil-phase aliphatic solvent and then heating, stirring and polymerizing the mixture. Provided are a preparing method of a coagulant having the characteristic where much of the cationic water-dispersible polyacrylamide copolymer particles prepared by using kosmotropic salt is contained in the emulsion coagulant, and the coagulant.
