Abstract

See full text

Disclosed are a core-shell structure membrane scale inhibitor and a preparation method therefor, wherein the core-shell structure membrane scale inhibitor has a core emulsion obtained via emulsion polymerization, and a shell structure obtained via ultraviolet-light grafting functional monomers. The preparation method has first preparing a core by using an emulsion polymerization process, adding a reactive photo-initiator in the later stage of polymerization, so that the reactive photo-initiator is grafted on the surface of the core, and finally initiating the polymerization of functional monomers by means of ultraviolet light to obtain a core-shell structure membrane scale inhibitor. The surface structure of the core is modified, such that a large number of ionizable groups are grafted on the surface thereof, and thus, a large number of scaling ions such as Ca2+, Mg2+ and Al3+ can be adsorbed.
