Problems solved by technology

[0006] Although a variety of technical solutions have been proposed for antifouling materials in the prior art, the existing antifouling coatings can only use traditional single low-toxic antifouling agents because they cannot use highly toxic antifouling agents. Marine attached animals such as barnacles, mussels, etc. have a certain killing effect, but are not very lethal to attached algae. These algae grow rapidly, and the individual plants are large, which seriously pollutes the cages; Most of them are woven by nylon wires. Due to the high hardness of traditional cage coatings, the adhesion to flexible materials such as nylon wires is poor. Cracking and falling off of the layer, resulting in short service life and high maintenance costs

Abstract

Aquaculture net cage antifouling paint comprises the following components of zinc acrylate resin, diisononyl phthalate, nano-silver powder, nonanoic acid vanillyl amide, zinc pyrithione, algaecide preventol A6, 10-35 parts of zinc oxide by weight, wetting dispersant, anti-settling agent, talcum powder and an organic solvent. The invention further discloses a preparation method of the antifouling paint. Compared with the prior art, the antifouling paint and the preparation method thereof have the advantages that the compounded antifouling agent has complementary advantages, the existing antifouling agent system is widened, excellent killing property for a plurality of marine fouling animals and algae is brought, no poison and no residue properties are realized. An antifouling coating has certain flexibility, and improves the adhesion, the mechanical performance and the durability.

Description

technical field [0001] The invention relates to a coating, in particular to an antifouling coating applied to net cages, which has the effect of killing marine attached animals and algae, so that the net cages have an antifouling function. The invention also discloses a preparation method of the paint. Background technique [0002] With the gradual decline of offshore fishery resources, the fishery resources obtained by traditional fishing operations are far from being able to meet the increasing demand for various seafood products in people's daily lives. The coastline of the country is developing rapidly, and the country is gradually increasing investment in scientific research and publicity for offshore cage culture. [0003] The cages used in offshore aquaculture are placed in seawater for a long time, and are easily fouled by marine organisms such as shellfish and algae. At the same time, a large number of marine organisms will accelerate the consumption of water-solub...
