Description
SPECIFICATION TITLE OF THE INVENTION: ANTIFOULING COATING COMPOSITION, AND FISHING NET, FISHING NET GEAR, AND UNDERWATER STRUCTURE COATED 5 WITH ANTIFOULING COATING COMPOSITION TECHNICAL FIELD [0001] The present invention relates to an antifouling coating composition for .0 preventing, over a long period, aquatic fouling organisms from attaching to fishing nets for cultivation or fixed nets, fishing net equipments used for the fishing nets such as float and rope (hereinafter, collectively referred to as fishing net-related substances), underwater structures such as coolant conduit raceway tubes in power plants, and relates to fishing net-related substances and [5 underwater structures with the antifouling coating composition applied thereon. BACKGROUND ART [0002] When fishing net-related substances and underwater structures are used ,0 without applying thereon an antifouling coating composition, various aquatic fouling organisms, such as seaweeds, barnacle, serpula, sea moss, mollusks and the like attach thereto, since they are placed in seawater for a long time. This would inhibit water from penetrating through the fishing nets, causing mass death of fish due to shortage of oxygen and outbreak of infectious disease. Then, 25 the fish cannot be shipped and result in heavy damage, In addition, if such organisms attach to the cultivation nets or to the fixed nets, the nets would become heavy. This would become problematic since the fish may swim away if the nets sink, and the nets itself may flow out, Therefore, frequent replacement 1.
of the nets would become necessary, and such maintenance would require large amount of labor and cost. [0003] In order to prevent these aquatic fouling organisms from attaching, various 5 antifouling coating compositions have been widely applied to the fishing net-related substances and to the underwater structures. Among the antifouling coating compositions, antifouling coating compositions containing copper-based chemical agents such as copper oxide (1}, copper glass, copper pyrithione and the like show a certain degree of effect to prevent shellfish such as tO mussels, barnacle and serpula from attaching, Therefore, they have been widely used. [0004] As an example of antifouling coating composition which show excellent effect against animals such as barnacles and serpula and coelenterates such as 15 hydrozan, a composition which is formulated with copper oxide (I) and a particular polyether modified silicone oil has been disclosed (Patent Document 1). In addition, an antifouling coating composition which is formulated with copper pyrithione in addition to the copper oxide (I) and the particular polyether modified silicone oil has also been disclosed (Patent Document 2). 20 [0005] However, since copper oxide (1) employed for these antifouling coating compositions is difficult to dissolve in water, they are difficult to ionize. Therefore, repellent effect against aquatic fouling organisms was not sufficient, and the antifouling effects of the antifouling coating compositions were not 25 sufficient. [00061 Here, an antifouling coating composition which employs monovalent copper-containing soluble copper glass in place of the copper oxide (1), and employs a metal pyrithione in combination, has been disclosed (Patent 2 Document 3). Although the amount of copper ion eluted from the monovalent copper-containing soluble copper glass employed in the antifouling coating composition is larger than that eluted from the copper oxide (I), such amount is still insufficient to exhibit sufficient repelling effect against aquatic fouling 5 organisms. Therefore, the market still remains unsatisfied. [0007] Furthermore, an antifouling coating composition which employs divalent copper-containing copper glass has also been disclosed (Patent Document 4). However, the repelling effect of such antifouling coating composition was still to insufficient. [00081 Therefore, there has been desired development of an antifouling coating composition which shows superior physical properties, possesses excellent workability when applying the coating composition to fishing nets, and exhibits 15 long-term antifouling effect in the sea area where animals such as barnacles and serpula, and coelenterates such as hydrozan show high activity PRIOR ART REFERENCE PATENT DOCUMENT 20 [0009] Patent Document 1: JP-A-Hei 8- 252533 Patent Document 2: JP-A- 2002 265849 Patent Document 3: JP-A- 2000-264804 Patent Document 4: JP-A- 2004-203774 25 SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION [0010] 3 The present invention has been made concerning the afore-mentioned problems, An object of the present invention is to provide an antifouling coating composition which can exhibit long-term antifouling effect in the sea area where animals such as barnacles and serpula, and coelenterates such as hydrozan 5 show high activity. MEANS FOR SOLVING THE PROBLEMS [0011] An aspect according to the present invention provides an antifouling coating 1o composition, including (A) divalent copper-containing copper glass, (B) a metal pyrithione and (C) titanium oxide, wherein the metal pyrithione contains copper or zinc as the metal, the antifouling coating composition further comprises a spreading resin, the copper glass (A) contains CuO by 25 to 40 % by mol, the content of the copper glass (A) by solid is 1 to 20 % by mass with respect to the 1.5 solids of the antifouling coating composition, the content of the metal pyrithione (B) by solid is 25 to 150 parts by mass with respect to 100 parts by mass of the copper glass (A), and the content of titanium oxide (C) by solid is 50 to 300 parts by mass with respect to 100 parts by mass of the copper glass (A). [0012] 20 The present inventors have conducted intensive research to develop an antifouling coating composition which exhibits long-term antifouling effect, and have found that when the antifouling coating composition contains three components of (A) divalent copper-containing copper glass, (B) a metal pyrithione, and (C) titanium oxide by a certain ratio, the antifouling coating 25 composition exhibits an extremely excellent long-term antifouling effect, and thus have accomplished the present invention. [0013] The mechanism on how the antifouling coating composition according to the present invention exhibits an excellent long-term antifouling effect remains 4 unclear, Here, in the experiments, antifouling coating compositions containing only the divalent copper-containing copper glass or antifouling coating compositions containing the divalent copper-containing copper glass and a metal pyrithione were not able to maintain the antifouling effect for a long time. 5 The antifouling coating compositions were able to exhibit an excellent long-term antifouling effect only when they contained all of the afore-mentioned three components. Since the active substance which provides the composition with the antifouling effect is the copper glass and the metal pyrithione, it is assumed that titanium oxide desirably controls the elution speed of the copper glass and 10 the metal pyrithione, and thus the active substances are eluted at a stable speed for a long period. [0014] Here, coating compositions containing the three components of monovalent copper-containing copper glass, a metal pyrithione and titanium oxide, and 15 coating compositions containing the three components of copper oxide (I), a metal pyrithione and titanium oxide were also investigated. However, both compositions were inferior in long-term antifouling effect when compared with the coating composition according to the present invention. Accordingly, it became obvious that the extremely excellent long-term antifou'ling effect 20 exhibited by the coating composition according to the present invention can be achieved only by allowing the antifouling coating composition to contain three components of (A) divalent copper-containing copper glass, (B) a metal pyrithione and (C) titanium oxide at a certain ratio, and thus the present invention has been accomplished. 25 ADVANTAGEOUS EFFECTS OF THE INVENTION [0015) Embodiments of the present invention provide an antifouling coating composition which can exhibit a long-term antifouling effect even in the sea area 5 where animals such as barnacles and serpula, and coelenterates such as hydrozan show high activity. DESCRIPTION OF EMBODIMENTS 5 [0016] The antifouling coating composition according to the present invention contains (A) divalent copper-containing copper glass, (B) a metal pyrithione and (C) titanium oxide, wherein the metal pyrithione contains copper or zinc as the metal, the antifouling coating composition further comprises a spreading resin, 10 the copper glass (A) contains CuO by 25 to 40 % by mol, the content of the copper glass (A) by solid is 1 to 20 % by mass with respect to the solids of the antifouling coating composition, the content of the metal pyrithione (B) by solid is 25 to 150 parts by mass with respect to 100 parts by mass of the copper glass (A), and the content of titanium oxide (C) by solid is 50 to 300 parts by mass with respect to 15 100 parts by mass of the copper glass (A). [00171 <Copper Glass (A)> The copper glass (A) employed in the present invention is a glass containing divalent copper, and the copper glass contains CuO by 25 to 40 % by mol. 20 There is no limitation to the composition of the glass so long as the glass can dissolve and elute copper at a desirable speed, Here, phosphate glass (glass containing P 2 0 5 as major component) is preferable, and P 2 0 5 -Na20-CuO-based glass is further preferable, When phosphate glass is employed, the amount of copper eluted with respect to the amount of glass dissolved can be increased, 25 compared with the case where silica glass is employed. The phosphate glass can also achieve stable elution. Therefore, the effect of the coating composition according to the present invention can be further improved when the composition is prepared with phosphate glass containing divalent copper In addition, since Na2O has a nature to break the bond between the phosphorus 6 atom and the oxygen atom of the phosphoric acid, the solubility of the glass component in water can be enhanced by adding Na2O to the phosphate glass. There is no limitation to the content of P 2 0 5 , Na 2 O and CuO. It is further preferable that the content of CuO is 30 to 40 % by mol, since Cu can be eluted 5 stably and desirably when the content is such. The molar ratio of P 2 0 5 to Na2O can substantially be the same (that is, P 2 03/Na 2 O=0.8 to 1.2) or can be different. Specific composition of the glass (molar ratio) is, for example, P20 3 /Na2O/CuO =35/35/30 or P20/Na20/CuO=30/30/40. [0018] .0 The copper glass (A) can be manufactured by formulating and blending the raw materials for the composition such as sodium phosphate, copper oxide (II) and the like, and then melting them at 1000 to 1200*C for 30 minutes to 2 hours. The molten glass is then poured onto an iron plate, cooled, and pulverized to 1 to 100 pm by a planetary ball mill. 5 [0019] The content of the copper glass (A) by solid is 1 to 20 % by mass with respect to the solids of the composition according to the present invention. For example, the content is 1., 2, 5, 10, 15 or 20 % by mass, or may be in the range between any of the two values referred herein. 20 [0020] <Metal Pyrithione (B)> Examples of the metal pyrithione (B) employed in the present invention include bis(2-sulfidepyridine- 1 -olato)copper (copper pyrithione), bis(2-sulfidepyridine-1-olato)zine (zinc pyrithione) and the like. Among these, 25 metal bis-pyrithiones (pyrithiones of divalent metals such as copper pyrithione and zinc pyrithione) are preferable, and copper pyrithione is particularly preferable. Ones that are commercially available can be employed as metal pyrithiones. Examples of such commercially available metal pyrithiones 7 include Copper Omadine Powder, Zinc Omadine Powder (both available from Arch Chemicals Japan, Inc) and the like. [0021] The content of the metal pyrithione (B) by solid is 25 to 150 parts by mass 5 with respect to 100 parts by mass of the copper glass (A), For example, the content is 25, 50, 100, 150, 200 or 250 parts by mass, or may be in the range between any of the two values referred herein, When the content is in such range, the antifouling effect against animals such as barnacles and serpula, and coelenterates such as hydrozan is particularly excellent. [0 [0022] Titanium Oxide (C)> Examples of the titanium oxide (C) employed in the present invention include titanium oxide of rutile type, anatase type or brookite type. These titanium oxides can be employed alone, or two or more kinds of the titanium 15 oxides can be employed in combination.

As the titanium oxide employed in the present invention, titanium oxide having an average particle diameter of 0.001 pm to 10 pm is preferable, and titanium oxide having an average particle diameter of 0, 1 pm to 3 pm is 25 particularly preferable. [0024] Here, the average particle diameter of the afore-mentioned titanium oxide is a value of a median diameter (50% cumulative particle diameter) calculated from volume average diameter measured by laser diffraction/ scattering method 8 Specifically, it is a value obtained when the laser diffraction/ scattering particle size analyzer, optical equipment of MT3300 available from NIKKISO CO., LTD was employed with methanol as the dispersion solvent, and the measurement was conducted at 25 *C. 5 [0025] As the titanium oxide employed in the present invention, titanium oxide having an oil absorption of 1mI/100g to 1000ml/100g is preferable, and titanium oxide having an oil absorption of 3mlO/100g to 50ml/100g is particularly preferable, to [0026] The surface of the titanium oxide employed in the present invention may be treated.

For example, the content is 50, 100, 150, 200, 250 or 300 parts by mass, or may be in the range between any of the two values referred herein. When the content is in such range, the effect 25 according to the present invention can be further enhanced. 10028] <0ther Additional Component> The antifouling coating composition employed in the present invention contains a spreading resin, and further contains eluting adjuvant, other 9 antifoulant, antisettling agent, anti-sagging agent, plasticizer, surfactant, antifoaming agents, dyes, pigments, organic solvent, water and the like, arbitrarily at an arbitrary ratio, so long as it does not alter the purpose of the present invention. 5 [0029] (Eluting Adjuvant) Examples of the eluting adjuvant include silicone oil, ethylene/ci-olefin copolymer, polybutenes, paraffins, vaselines, dialkylsulfide compound and the like.

Preparation was conducted so that 100 parts by mass of the fishing nets would be applied with 15 parts by mass of the antifouling coating composition. Here, the mass was based on dry coating, The fishing nets thus obtained were fixed onto an SUS frame with the size of 40x60 cm, and were immersed in the sea to of Owase-shi, Mie-prefecture, where the activity of aquatic fouling organisms is high, with the depth at the draft level using a raft. The antifouling properties were evaluated over 12 months by periodic observation. [0064] The evaluation was conducted by the following method. The area with the 1,5 aquatic organism attached (%) was evaluated by taking a picture of the fishing nets from above, after the predetermined time of the test (2, 4, 6, 8, 10 or 12 months) have passed, and then evaluating the area of the fishing nets occupied with the aqueous organism by visual observation, A: Area with the aquatic organism attached is 0% 20 B: Area with the aquatic organism attached is above 0% and less than 10% C: Area with the aquatic organism attached is 10% or more and less than 50% D: Area with the aquatic organism attached is 50% or more Results are shown in Table 2. 25 [00651 [Table 2] 22 Table 2 Antifouling Exampie Comparative Example Effect 2 3 4 5 6 12 3 4 5 6 7 8 | 9 1011 12 2nd month A A A A A A A A A A A A A - A |A- AI A 4th month A A A A A A C A A B A A A A 1 C B 6th month A A A A A A D B B C A A B 6 D D C C 8th month A A A A A A D C C D B B B C D D D D 1Oth month A A A A A A DDDD D D D D 12th month A A B B A B D D D D ID D D D [0066] It can be seen from Table 2 that the antifouling coating compositions of Examples I to 6 are excellent in long-term antifouling effect when compared with 5 any of the antifouling coating compositions of the Comparative Examples of 1 to 12. Examples 1 to 6 contain three components of divalent copper-containing copper glass, a metal pyrithione and titanium oxide. On the other hand, Comparative Example I contains only the divalent copper-containing copper 10 glass, and Comparative Examples 2 and 3 contain on ly the divalent copper-containing copper glass and a metal pyrithione, and Comparative Example 4 contains the divalent copper-containing copper glass and titanium oxide. The long-term antifouling effects of Comparative Examples 1 to 4 were far lower than those of Examples 1 to 6. These results revealed that it is 15 essential for the antifouling coating composition to include all of the three components mentioned above, in order to exhibit an excellent long-term antifouling effect. When the antifouling coating composition lacks any one of the three components, the long-term antifouling effect lowers drastically. In addition, in Comparative Examples 5 to 8, long-term antifouling effect was 20 studied for the antifouling coating composition containing the three components of monovalent copper-containing copper glass, a metal pyrithione and titanium oxide, or the antifouling coating composition containing the three components of copper oxide (1), a metal pyrithione and titanium oxide. Here, the long-term antifouling effect observed for all of the Comparative Examples 5 to 8 were far 23 lower than those of Examples I to 6. Accordingly, it became apparent that the long-term antifouling effect is highly improved only when divalent copper-containing copper glass was used with a metal pyrithione and titanium oxide. Therefore, similar result cannot be obtained when the monovalent t5 copper-containing copper glass or copper oxide (1) was employed. Comparative Example 9 is directed to an antifouling coating composition containing pyrithione and titanium oxide, but not the monovalent copper-containing copper glass. According to the results of the evaluation of antifouling effect for Comparative Example 9, attachment of aquatic organism to was observed when observation was conducted in the fourth month. The long-term antifouling effect was far lower than those of the Examples. The antifouling coating composition of Comparative Example 10 is obtained by adding zinc oxide to the antifouling coating composition of Comparative Example 9. According to the results of the evaluation of antifouling effect for 15 Comparative Example 10, attachment of aquatic organism was observed when observation was conducted in the fourth month. Therefore, it became apparent that the long-term antifouling effect cannot be improved by the addition of zinc oxide. The antifouling coating composition of Comparative Example 11 is obtained 2O by adding zinc dimethyldithiocarbamate to the antifouling coating composition of Comparative Example 9. According to the results of the evaluation of antifouling effect for Comparative Example 11, the long-term antifouling effect was improved by some extent, however, attachment of aquatic organism was observed when observation was conducted in the fourth month, Therefore, it 25 became apparent that the long-term antifouling effect cannot be improved considerably by the addition of zinc dimethyldithiocarbamate. The antifouling coating composition of Comparative Example 12 is obtained by adding tetraethylthiuram disulfide to the antifouling coating composition of Comparative Example 9. According to the results of the evaluation of 24 antifouling effect for Comparative Example 12, attachment of aquatic organism was observed when observation was conducted in the fourth month. Therefore, it became apparent that the long-term antifouling effect was hardly improved by the addition of tetraethylthiuram disufide. 5 Furthermore, it became apparent that Examples 1, 2 and 5 which contain copper pyrithione were high in long-term antifouling effect when compared with Examples 3, 4 and 6 which contain zinc pyrithione, 25
