Problems solved by technology

[0005] At present, in the research of biodegradable antifouling coatings, degradable polyurethane is used. However, due to the uncontrollable degradation rate of the resin itself and the physical and mechanical properties of degradable polyurethane, the antifouling agent in the coating cannot be released stably. , short antifouling period, and poor resistance to seawater immersion

Abstract

The present invention relates to the technical field of marine antifouling coatings, in particular to a preparation method and application of a degradable antifouling resin, including: the step of synthesizing a degradable polylactic acid block polymer P1, whose raw materials are lactic acid, polyol and / or Or polyester polyol, catalyst, A solvent; the step of synthesizing polylactic acid block polymer base acrylate P2, its raw material is P1, triethylamine, methacryloyl chloride, B solvent; synthetic degradable acrylate polymer P3 The step, its raw material is P2, methacrylate monomer, initiator, C solvent. The degradable antifouling resin prepared by the invention can be applied to the preparation of degradable antifouling coatings, and the prepared antifouling coatings have excellent resistance to seawater immersion and controllable degradation, thereby controlling the release of antifouling agents and obtaining long-term antifouling effects.

Description

technical field [0001] The invention relates to the technical field of marine antifouling coatings, in particular to a preparation method and application of a degradable antifouling resin. Background technique [0002] At present, tin-free self-polishing coatings occupy a dominant position. It overcomes the disadvantages of high toxicity of traditional organotin self-polishing antifouling coatings, and at the same time has the advantages of self-polishing antifouling coatings. The coating dissolves polymers through ion exchange in seawater. , release antifouling agent, and then play an antifouling effect. Such polymers mainly include copper acrylate polymers and zinc acrylate polymers. Another class of polymers are silicone acrylate polymers, which are anti-fouling by silane hydrolysis. Their principles are that only the resin on the surface of the coating that is in contact with seawater is hydrolyzed and water cannot penetrate the interior of the coating film. When the s...
