Preparation method of olefin ether and unsaturated carboxylic acid copolymer anti-sludging agent

The present invention belongs to the technical field of water treatment, there is provided a process for preparing an olefin and an unsaturated carboxylic acid ether copolymer scale inhibitor, scale inhibitor of the synthesis of the following steps: (1) an olefin basified ether, to the reaction system halo acid was added, heating the reaction, filtration, distillation, and dried in vacuo to give ether carboxylate reaction of an olefin monomer; (2) an ether carboxylic acid monomer and an olefin-unsaturated carboxylic acid under the action of an initiator system, after warming the reaction, cooled to room temperature, ether and an olefin unsaturated carboxylic acid copolymer scale inhibitor. Scale inhibitor containing strongly hydrophilic polyether structure and a large number of carboxyl groups, water solubility, easy to effect with calcium ions present in the circulating water system occurs, has excellent scale inhibition performance of calcium carbonate, calcium sulfate and calcium phosphate.
