Abstract

The invention belongs to the technical field of marine antifouling materials, and discloses a main chain degradable polyacrylic acid copper resin, a preparation method and application thereof. The main chain degradable copper polyacrylate resin is prepared from the following components in parts by weight: 100 parts of acrylate prepolymer, 5-50 parts of copper-containing compound, 0-75 parts of monocarboxylic acid, organic solvent 5-150 parts; the acrylate prepolymer is mainly prepared from the following components: solvent, cyclic monomer, vinyl monomer, (meth)acrylic acid, and initiator. The resin side chain copper ester bond and the main chain polyester segment of the present invention can be hydrolyzed under the attack of seawater, which solves the dependence of traditional self-polishing materials on the speed of the ship, and can make the coating surface self-sufficient through hydrolysis and degradation in static seawater. Update, effectively control the release of antifouling agent at a constant rate, meet the antifouling requirements of low-speed ships and offshore oil production platforms and other facilities; it has excellent drag reduction performance.

Description

technical field [0001] The invention belongs to the technical field of marine antifouling materials, and relates to a copper polyacrylate resin for marine antifouling coatings, in particular to a copper polyacrylate resin with degradable main chain and its preparation method and application; the resin is used for preparing Marine antifouling coatings. Background technique [0002] In recent years, limited land resources have been over-exploited, and people have gradually turned their attention and footprints to the ocean, which has also set off a wave of ocean fever. However, the serious problem of marine biofouling lies in front of people, and has been plaguing researchers all over the world. At present, the application of self-polishing marine antifouling coatings is the method with the highest commercial degree, the most mature technology and the longest service life. The main resins used for self-polishing antifouling coatings include polyacrylate silane resin, polyacr...
