Abstract

Provided is an antifouling coating composition capable of exhibiting an antifouling effect for a long period of time even in ocean water containing highly active barnacles, serpula, and other animal species, as well as hydrozoans and other coelenterates. This antifouling coating composition comprises (A) copper glass containing divalent copper, (B) metal pyrithiones, and (C) titanium oxide, wherein the metal of the metal pyrithiones is copper or zinc; the composition further contains a spreading resin; the content of copper in the copper glass (A) is 24-40 mol%; the content of the copper glass (A), in terms of solid content, is 1-20 mass% of the solid content of the antifouling coating composition; the content of the metal pyrithiones (B), in terms of solid content, is 25-150 parts by mass per 100 parts by mass of the copper glass (A); and the content of the titanium oxide (C), in terms of solid content, is 50-300 parts by mass per 100 parts by mass of the copper glass (A).

Description

【Technical field】 [0001] The present invention relates to equipment for long-term prevention of attachment of aquatic fouling organisms to fishing nets for cultivation or fixed nets, buoys and ropes used in them (hereinafter, they are sometimes collectively referred to as fishing nets) and power stations An antifouling coating composition on underwater structures such as cooling water conduits; and fishing nets and underwater structures coated with the antifouling coating composition. 【Background technique】 [0002] Since fishing nets and underwater structures have been installed in the sea for a long time, they will adhere to various aquatic fouling such as seaweed, barnacles, worms, bryozoans, and molluscs when they are used without an antifouling coating composition. biology. As a result, the circulation of seawater between the inside and outside of the fishing net becomes poor, resulting in large losses such as a large number of farmed fish dying due to lack of oxygen, ...
