Abstract

The invention relates to a synthesis technology of zinc acrylate or copper acrylate self-polishing anti-fouling resin. The synthesis technology comprises the following steps: firstly, zinc acrylate or copper acrylate micromolecular monomer is generated; and secondly, zinc acrylate monomer or copper acrylate monomer and acrylic soft-hard monomers are used to perform radical polymerization in mixed solvent under the action of initiator and prepare zinc acrylate or copper acrylate self-polishing anti-fouling resin with a certain hydrolysis ratio. By adopting the synthesis technology, the reaction time can be greatly shortened, thus the production cost can be reduced by 20-30% and the synthesis technology can be optimized. The technology belongs to the technical field of the ocean ship anti-fouling paint. The zinc acrylate or copper acrylate resin prepared by the technology has good adhesion to the substrate and has scratch resistance; the pencil hardness of the resin is above 4H; and the resin has a certain self-polishing rate and can be used as the main film forming material of the ocean ship anti-fouling paint.

Description

Technical field [0001] The present invention involves a synthetic process of a zinc acrylic or acrylic self -polishing resin, which is a small molecule of a zinc forml acrylic or acrylic copper.In the hybrid solvent, the spontaneous polymerization of acrylics or copper -polishing anti -dine -proof resins with a certain hydrolysis rate caused by a certain hydrolysis rate belongs to the field of marine ship's anti -dirt -proof coating technology. Background technique [0002] The main growth of marine dirty creatures is mainly growing under the watershed section, buoyant, coastal factory cooling water pipelines, coastal facilities, submarine cables, floating bridges, and fishery facilities.The service life will also significantly increase the quality of the hull, resulting in a decline in the actual loading capacity of the ship.In addition, they can make the friction coefficient on the surface of the hull, which seriously affects the speed of the ship and increases fuel consumption...
