The invention belongs to the technical field of cation exchange resin, and particularly relates to a preparation method of a solvent-free gel type styrene cation exchange resin. Carrying out suspension polymerization on styrene, divinylbenzene and a third monomer under the action of an initiator to prepare white balls; and (3) carrying out sulfonation reaction on the white balls and sulfuric acid, and carrying out post-treatment after the reaction is finished to obtain the solvent-free gel type styrene cation exchange resin. The preparation method of the solvent-free gel type styrene cation exchange resin does not use a white ball swelling reagent 1, 2-dichloroethane, improves the safety of resin products, simplifies the refining process and reduces the refining cost of enterprises. |
