Fujibbo is applied to parts that are in constant contact with seawater, such as the bottom of ships, equipment placed in seawater such as buoys, underwater structures such as dam auxiliary equipment, cooling water intake channels for thermal power plants and various industries, etc.
Animal organisms such as oysters, mussels, water bugs, celluloids, bryozoans, and sea squirts, as well as plant organisms such as sea lettuce and blue seaweed, propagate on ships, so ships need to reduce their sailing speed, increase fuel consumption, and clean the bottom of the ship. In the case of offshore structures, it causes inconvenience in handling and operation, and in the case of intake channels, intake channels become blocked and the amount of water intake decreases. This causes problems.

に関しては使用禁止の措置が取られている。Therefore, antifouling paints containing organic tin compounds such as copper oxide and bistributyltin oxide have conventionally been used to prevent problems caused by the adhesion and propagation of seawater and freshwater harmful organisms. Organotin compounds such as bistributyltin oxide have already become a social problem due to their toxicity and tendency to accumulate in fish bodies, and measures have been taken to ban their use in fishing nets.
また、銅酸化物及び銅の化合物は広く、取水路及び船底
部用の防汚塗料として広く使用されているが、重金属で
ある銅を含有しているため、その毒性が強く、好ましい
防汚塗料とは言えない。In addition, copper oxides and copper compounds are widely used as antifouling paints for intake channels and ship bottoms, but since they contain copper, a heavy metal, they are highly toxic and are preferred as antifouling paints. It can not be said.
本発明は有機スズ化合物及び銅化合物を含まず、安全性
が高い防汚剤を開発し、漁網、船舶の底部、海洋構築物
等に藻類、貝類の付着を防止するものである。The present invention aims to develop a highly safe antifouling agent that does not contain organic tin compounds or copper compounds, and prevents algae and shellfish from adhering to fishing nets, the bottoms of ships, marine structures, etc.

とにより得られる。Zinc 2-mercaptobenzothiazole is used to prevent aquatic biofouling by mixing the compound with synthetic resins such as acrylic resin, vinyl acetate resin, and chlorinated rubber, and solvents to make paints that can be used on fishing nets, the bottom of ships, and the ocean. Apply to the construct. This coating material is obtained by mixing 2 to 30 parts by weight of zinc 2-mercaptobenzothiazole, 5 to 30 parts by weight of the above-mentioned synthetic resin, 40 to 80 parts by weight of a solvent, and appropriate amounts of other pigments.
