Abstract

The invention discloses an anti-cracking zinc acrylate antifouling paint and a preparation method thereof, and the antifouling paint comprises the following raw materials by weight: 30-40 parts of zinc acrylate resin, 15-20 parts of a pigment, 10-15 parts of an organic solvent, 25-35 parts of a modified antifouling agent, 4-8 parts of an auxiliary agent, and 8-10 parts of amino silicone oil. The modified antifouling agent is mainly prepared by reacting modified graphene, modified montmorillonite, isopropanol, titanium tetrachloride, sodium citrate, a copper acetate solution, sodium hydroxide and hydrazine hydrate. According to the anti-cracking zinc acrylate antifouling paint and the preparation method thereof, the process design is reasonable, the operation is simple, the prepared antifouling paint not only has excellent bactericidal antifouling performance, but also has excellent flexibility and anti-cracking performance, can be applied to the field of marine antifouling, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of antifouling coatings, in particular to an anti-cracking acrylate zinc antifouling coating and a preparation method thereof. Background technique [0002] Marine biofouling is ubiquitous in the marine environment and is a major problem facing the shipping industry. The most common marine fouling organisms are algae, hydra, barnacles, oysters, etc. Their attachment will lead to increased hull weight and navigation friction, increased power and fuel consumption, blockage of marine pipelines, and failure of marine instruments, etc. , which brings great inconvenience to actual navigation. [0003] Based on this situation, research on antifouling coatings has gradually become a hot spot of our attention. Antifouling coatings are coatings used to prevent marine organisms from attaching, decaying, and fouling, and to keep water-soaked structures such as ships, docks, and sonars clean and free. , Antifouling coa...
