Abstract

The invention relates to a waterborne acrylic macromolecular compound and salts thereof, as well as preparation methods and applications thereof. The method comprises the following steps of: dissolving hydrophilic acrylic monomers containing amino, acrylic monomers containing hydroxyl, acrylic monomers containing quaternary ammonium salts and acrylic monomers containing carboxyl in water, then adding a water-soluble azo compound as an initiator, and dropwise adding the monomer hybrid solution containing the initiator to water or alcohol-water solution for copolymerization reaction. Stain-proof paints prepared by using metal salts of the waterborne acrylic macromolecular compound can effectively prevent adhesion of fouling organism in seawater, and have the advantage of being environment-friendly.

Description

【Technical field】 [0001] The invention belongs to the technical field of polymer materials. More specifically, the present invention relates to a water-based acrylic polymer compound, a preparation method of the compound, and an application of the compound. 【Background technique】 [0002] The surface of marine facilities immersed in seawater will form a complex biofouling layer due to biological action. This phenomenon of organisms attaching to the surface of marine installations and causing them to be adversely affected is called marine biofouling. Marine biofouling is extremely harmful. As far as ships are concerned, on the one hand, it will accelerate the corrosion of the hull and shorten the service life of the ship; on the other hand, it will increase the weight of the hull itself, which will increase the resistance of the ship's navigation, thereby reducing the speed of the ship and increasing fuel consumption. . According to statistics, when the marine biofouling r...
