[Industrial Field of Application] The present invention can be applied to the submerged surfaces of structures such as fishery and aquaculture nets, ships, bridges, and cooling water pipes of thermal power plants to protect against aquatic organisms such as shellfish such as barnacles and blue seaweed. The present invention relates to an antifouling paint composition that is effective in preventing the attachment and parasitism of algae and the like. In recent years, antifouling agents have been widely used as paints to prevent seaweed and shellfish from adhering to fishing nets and boat bottoms, as organic tin compounds such as tributyltin oxide have antibacterial and antifouling properties. Recently, regulations on its use have been considered because it is poorly degradable by microorganisms, accumulates frequently in the environment, and is toxic. [Problems to be Solved by the Invention] The object of the present invention is to provide an underwater antifouling paint that does not cause environmental pollution under such conditions. [Means for Solving the Problems] The present invention was created as a result of intensive studies in view of the above-mentioned actual situation, and the outline thereof is as follows. 15 to 30 parts by weight of acrylic resin, 5 to 10 parts by weight of rosin, 10 to 30 parts by weight of cuprous oxide, and 10 to 30 parts by weight of copper powder shown below.
The paint consists of 30 parts by weight, 5 to 10 parts by weight of patina, and an appropriate amount of solvent. (In the formula, R and R' represent a hydrogen atom or a methyl group.) One or more compounds represented by 1 to 10
It is a copolymer obtained by copolymerizing 90 to 99 parts by weight of one or more unsaturated compounds consisting of acrylic esters and methacrylic esters. [Function] Examples of the compound (monomer) represented by the above general formula include hydroxyethyl methacrylate, hydroxyethyl acrylate, hydroxypropyl methacrylate, and hydroxypropyl acrylate. Examples of unsaturated compounds to be copolymerized with these monomers include methyl acrylate, ethyl acrylate, α-chloroethyl acrylate, propyl acrylate, butyl acrylate, amyl acrylate, hexyl acrylate, and cyclohexyl acrylate. , octyl acrylate,
Dodecyl acrylate, octadecyl acrylate,
Examples include acrylic esters such as benzyl acrylate and phenyl acrylate, and methacrylic esters such as methyl methacrylate, ethyl methacrylate, butyl methacrylate, hexyl methacrylate, octyl methacrylate, and octadecyl methacrylate. Furthermore, when used as a marine paint, it forms a smooth coating film and has little resistance to movement underwater. And this acrylic resin is used for coating film formation.
~30 parts by weight is preferable; if it is less than 15 parts by weight, the amount of adhesion to the object will be too small and a tough film will not be obtained, and if it exceeds 30 parts by weight, the resin component will be too large and a tough film will not be obtained. A film cannot be obtained. In addition, rosin gradually dissolves into seawater due to its alkalinity, helping the elution of copper ions.
If the amount is less than 5 parts by weight, the elution rate will be slow, and if it exceeds 10 parts by weight, the elution rate will be too fast, resulting in a decrease in antifouling performance. This is not desirable as it increases. Next, cuprous oxide, copper powder, and patina all turn into copper ions in water, and the secretions produced when organisms attach to them prevent the adhesion and propagation of the secretions due to the copper ion effect, especially when Cu + →Cu ++. It exhibits an antifouling effect, including changes in The reason why three types of copper-based substances, cuprous oxide, copper powder, and verdigris, are used together is that the elution rate of Cu ions into water is different, and copper powder has a lower initial rate than seawater.
The initial antifouling effect can be enhanced due to the large amount of Cu + eluted, and cuprous oxide has a higher leaching effect than copper powder due to the large amount of Cu ++ eluted and the change from Cu + to Cu ++ in water.
Since the generation of Cu ++ is slow, an initial antifouling effect cannot be expected, but after a certain period of time, Cu ++ gradually forms in the water, achieving a sustained antifouling effect. Furthermore, the patina has extremely low elution of Cu + in seawater, and is formulated to achieve a long-lasting antifouling effect. The copper powder used in the present invention may be any of electrolytic copper powder, sprayed copper powder, and ground copper powder, but ground copper powder is usually used for paints. As the patina, copper salts such as basic copper carbonate, basic copper acetate, basic copper chloride, and basic copper sulfate can be used alone or in the form of a mixture. If the content of copper powder and cuprous oxide is less than 10 parts by weight, the contact area of copper with seawater per unit area will be insufficient and the antifouling effect will be insufficient, and if the content exceeds 30 parts by weight, copper ions will be produced. The amount of elution is too large, making it impossible to obtain a normal coating film condition. If the patina is less than 5 parts by weight, the amount of copper ions eluted will be too small and the long-term antifouling effect will be insufficient, and if it exceeds 10 parts by weight, it will be difficult to obtain a normal coating.

In other words, the three copper-based components of the present invention achieve a long-term antifouling effect through the gradual elution of Cu + and Cu ++ . Effects of the Invention As is clear from the above specific effectiveness test, the product according to the present invention exhibits an antifouling effect for a very long period of time.
Furthermore, there is no risk of causing any pollution.
