Description

  The present invention relates to a repellent for aquatic organisms and a repelling method using a repellent for aquatic organisms.

As is well known, living organisms in seawater have a self-defense function such as constantly eluting various chemical substances, protecting their territory, and preventing (repelling) other organisms (vegetation). ing. Artificially created technology is considered a repellent and / or repellent solvent. These repellents are not all-purpose, but vary according to various plants (seaweeds) or animals (shellfish), and their repelling and elimination are said to be very difficult, and their research and experimentation are frequent. It became a situation to be done. Changes in the ecosystem of aquatic organisms due to air and / or sea pollution and shifts in the growth area of aquatic organisms have been screamed, and changes in the global environment are becoming a problem.
From the above situation, there are various related inventions.

  Document (1) is “Method of blending an aquatic organism adhesion inhibitor or adhesion promoter” in JP-A-6-346416, and the outline thereof is an aquatic organism adhesion inhibitor and accelerator in a fibrous, granular or granular form. It is a method of supporting a powdery carrier in an object or a coating material, characterized in that the ability to prevent or promote the adhesion of aquatic organisms is maintained. However, this invention is problematic because it cannot be expected to adopt a structure that is applied directly to an object used in seawater. Further, since the carrier is limited to a structure having a capillary action, there remains a problem that lacks versatility.

  Reference (2) is “Triphenylboron Derivatives and Their Uses” of JP-A No. 2002-302494, and the outline thereof is miscibility with water-repellent fouling organisms, miscibility with antifouling components and paint resins, and dissolution in solvents. An antifouling agent with improved properties, which is a raw material for triphenylboron-containing polymers showing an excellent anti-adhesion effect on varicella-fouling organisms such as coelenterate, shellfish, tubules and polychaetes, or antifouling ingredients It is useful as a feature. However, this invention is not a repellent for aquatic organisms, which does not employ a porous material for paint resin, so that it can be eluted and sustainedly released in seawater over time to maintain the repellent effect over a long period of time. .

  Document (3) is “Anti-fouling paint” disclosed in JP-A-8-85767, and its outline is to prevent adhesion of waterpox fouling organisms to the structure surface by forming a slime layer on the structure surface. It is an antifouling paint, characterized by having no adverse effects on useful organisms in the water and no risk of accumulation of harmful substances in seafood. However, the present invention has a structure in which the contaminated paint is gradually eluted by being scraped off by an external factor such as a wave, so that it is eluted and gradually released over time in seawater, and the repelling effect is maintained over a long period of time. It is not a possible repellent for aquatic life.

  Reference (4) is “Aquatic organism anti-adhesion paint” disclosed in JP-A-5-70716, and its outline is that an aquatic (aquatic) organism repellent substance is embedded or fixed in a porous fine powder, and the repellent component This is an aquatic organism adhesion prevention paint that can regulate the elution of the aquatic organisms, and controls the life of the repellent component by adjusting the elution rate of the repellent component for the paint that is applied to the bottom of the ship to prevent the aquatic organism from adhering. It is possible to do. However, the present invention is a configuration in which two or more kinds of metal powders or copper powders having different ionization tendencies and a water-absorbing resin are embedded or fixed in the porous fine powder, and the use of the metal powders is little in terms of environment. There seems to be a problem.

  Reference (5) is “collar containing a novel gel preparation for controlling the arthropod invasion of animals” of JP-A-2000-63206. The outline is a collar obtained by using a mixture of an active substance in an organic solvent and a gel containing a gelling agent, and a polymer material such as porous polyamide for the support membrane, which is harmful to the arthropods. It is characterized by protection from living things. However, it is considered that this invention is completely different from the aquatic organism repellent and has a number of problems in use.

  Document (6) is “Repellent active sustained-release porous microparticles and applications thereof” disclosed in JP-A-2002-308705. An example of the outline is an ink (solution) containing sustained-release inorganic porous microparticles, or a paper. -A long-term repellent activity effect due to sustained-release inorganic porous microparticles carrying a repellent active substance, such as a repellent active effect of sanitary pests such as cockroaches and mites, etc. Features. However, since the present invention employs an organic solvent, there is room for improvement in environmental problems, and it is a sanitary pest repellent and has a repellent effect in a certain field, or a sustained-release inorganic It is a sustained release in the air by porous microparticles, and it is not a repellent for aquatic organisms that can be dissolved and released in seawater over time to maintain the repellent effect over a long period of time.

FIG. 4 is a chart (diagram) showing the results of the underwater test of FIGS. 1 and 2 and FIG. Based on these materials, the superiority or inferiority of the features of the present invention will be described below.

  FIGS. 1-1 to 1-7 are schematic diagrams in which a specific algae and a porous paint as a repellent substance are used as an example of the repellent A of the present invention on the seaweed X attached to the block 1. FIG. Reference numeral -1 denotes an underwater block 1 (an underwater object such as a stone or an undersea object). Fig. 1-2 is intended to prevent reproduction and / or planting (reproduction) of seaweed X to this block 1, and the repellent A for seaweed X is applied to the entire block 1 on land. And place it in the sea. FIG. 1-3 shows a state in which the required time has elapsed in the sea, and shows the situation where the spore X1 of the seaweed X has floated toward the block 1, and the repellent A is included in the spore X1. Multiple things that react instantaneously (with a repellent effect) to the repellent (not shown), and to a certain extent reproductive and / or vegetative (reproductive) suppression (lead to death) It can be considered as multiple things. 1-4 shows the seaweed X that can reproduce to some extent. However, it was the situation before the applied repellent A eroded the living body and suppressed growth, and in this example, three locations (three strains) were shown. As shown in the figure, the grown one can observe the growth of the stem X3 and / or the leaf body X4. However, as shown in FIG. 1-5, this reproduction is temporary, and after a few days, the applied repellent A acts to suppress the action of the root X2 of the seaweed X, And the depletion or atrophy of the stem X3 and / or the leaf body X4 progresses, and a part of the stem X3 falls off due to a decline in reproductive function. In this example, it is in the state where about 2 shares were peeled off. After that, as shown in FIG. 1-6, after several days, all three strains are peeled off by the same reasoning as described above, and the already dried dead seaweed X is separated from the block 1 It is floating in the sea. Moreover, FIGS. 1-7 shows the condition after exfoliation of the seaweed X. For example, the surface of the block 1 with the repellent A can be visually observed. The block 1 is in the initial state with no seaweed X attached. Then, after several years, the repellent A fades away and, for example, the surface of the block 1 becomes visible. As described above, this repellent A is composed of an anti-algae agent and a porous polyamide resin paint and / or a porous paint such as a porous polymer paint having continuous porous or open cell characteristics at an appropriate mixing ratio. Create by mixing with stirring. The mixing ratio is not limited. For example, the mixing ratio is adjusted according to the length of elution time (long and short of repellent effect), the amount of propagation of seaweed X and the like (hereinafter, the same applies to other examples). Further, the adjustment of the application amount of the repellent A and / or the adjustment of the mixing ratio can be adjusted according to the length of the elution time, the size of the propagation amount, and the like. Further, the length of the elution time and the like is adjusted in consideration of the application amount of the repellent A and / or the water quality and climatic conditions such as seawater and fresh water and / or the state and material of the object such as the block 1.

FIG. 2-2 intends to prevent the reproduction of the shellfish Y on the hull 2, and the repellent B for the shellfish Y is applied to the entire hull 2 on land. FIG. 2-3 shows a state in which the required time has elapsed in the sea, and shows a situation in which the shellfish Y climbs up toward the hull 2, and the shellfish Y includes the repellent B. In contrast, there are a plurality of things that react instantaneously (with a repellent effect) and repel (not shown), and a plurality of things that are suppressed to a certain extent and reproductive and / or vegetative (reproductive) shown as an example. Conceivable. However, as shown in FIG. 2-4, this reproduction is temporary, and after a few days, the applied repellent B acts, suppresses the action of the limb Y1 of the shellfish Y, and The extremity Y1 is killed or attenuated, and the shellfish Y is separated from the hull 2. Thereafter, as shown in FIGS. 2-5 and 2-6, all shellfish Y are peeled off, and the peeled dead shellfish Y is separated from the hull 2 and retreats from the seabed. Moreover, FIG. 2-7 shows the situation after the shellfish Y is peeled off. For example, the surface of the hull 2 with the repellent B is visible. The hull 2 is in an initial state without the attachment of shellfish Y. Then, after a few years, the repellent B fades away and, for example, the surface of the hull 2 is visible. The repellent B is created by stirring and mixing a specific inorganic acid and a porous paint at an appropriate mixing ratio. The mixing ratio is not limited. For example, the mixing ratio is adjusted according to the length of elution time (long and short of repelling effect), the amount of breeding of shellfish Y and the like. Furthermore, the adjustment of the application amount of the repellent B and / or the adjustment of the mixing ratio can be adjusted according to the length of the elution time, the size of the propagation amount, and the like. Further, the length of the elution time and the like is adjusted in consideration of the application amount of the repellent B and / or the water quality and climatic conditions such as seawater and fresh water and / or the state and material of the object such as the hull 2.

  In the present invention, since the specific inorganic acid which is a repellent substance elutes from the porous paint over time, it was confirmed from the test results described later that at least this state lasts for one year to several years. Here, as a specific inorganic acid which is a repellent substance, “sulfamic acid (inorganic acid)” can be mentioned.

FIGS. 13-1 to 13-9 show specific inorganic acid and porous paint F (repellant) which are the repellent substance E of the present invention, the permeating repellent substance E, the shellfish Y attached to the hull 2, and the like. It is a schematic diagram explaining the relationship.

  FIGS. 12-1 to 12-9 are schematic diagrams in which a specific algae that is the repellent C of the present invention is used for the seaweed X attached to the block 1, and FIG. 12-1 is a block 1 (stone, seabed). An underwater object such as an object). FIG. 12-2 intends to prevent the reproduction of the seaweed X to the block 1, and a specific algae that is a repellent C for seaweed is applied to the entire block 1 on land. After the application, the applied repellent substance C penetrates into the block 1 as time elapses. This state of penetration is shown in FIGS. 12-3 to 12-4. FIG. 12-3 shows the state of penetration, and FIG. 12-4 shows the state of penetration. Thereafter, the permeated repellent substance C is concealed with a porous paint D such as a porous polyamide resin paint and / or a porous polymer paint. Therefore, even if the block 1 is washed with seawater, under this condition, the repellent substance C cannot be diffused rapidly, and elution / sustained release (from the inside) through the porous body of the porous paint D Elution to the surface and / or sustained release) keeps the efficacy (the repellent properties and sustainability of the repellent can be secured. Other examples are the same). And even if the spore X1 of the seaweed X has floated toward the block 1 in the state where the required time has passed as shown in FIG. 12-5, the spore X1 contains the repellent substance C in the spore X1. There are a plurality of things that react instantaneously (having a repellent effect) and repel (not shown), and a plurality of things that are repressed to a certain extent (resulting in death) as shown as an example. FIG. 12-6 shows a state in which a small number of spores X1 that have passed through the repellent substance C have regenerated and become seaweeds X. However, since the applied repellent substance C is eluted and gradually released toward the surface of the block 1 through the porous body, it enters the living body of the seaweed X that reproduces in the block 1, and this seaweed This is the situation before the growth of X was eroded (penetrated) and the growth was suppressed. In this example, three locations (three strains) were shown. As shown in the figure, the grown one can observe the growth of the stem X3 and / or the leaf body X4. However, as shown in FIG. 12-7, this reproduction is temporary, and after a few days, the repellent substance C that has been eluted and released gradually acts, and the action of the root X2 of the seaweed X And the stem X3 and / or the leaf body X4 is depleted or attenuated, and a part of the stem X3 falls off due to a decline in reproductive function. In this example, it is in the state where about 2 shares were peeled off. After that, after several days as shown in FIG. 12-8, all three strains are peeled off due to the same reasoning as described above, and the dead seaweed X already peeled off is separated from the block 1 in the sea. The situation is floating. Moreover, FIG. 12-9 shows the situation after exfoliation of the seaweed X. For example, the surface of the block 1 containing the repellent substance C becomes visible. The block 1 is in the initial state with no seaweed X attached. Then, after a few years, the repellent substance C fades away and, for example, the surface of the block 1 becomes visible. And in this invention, since the specific algae which is the repellent substance C is eluted and sustained-released from the porous coating material D over time, it is a test mentioned later that at least this state continues for one year to several years. It was confirmed by the result. The length of elution time (the length of the repellent effect) is adjusted by adjusting the penetration depth of the repellent substance C, adjusting the amount of the repellent substance C to be permeated, and adjusting the coating amount of the porous paint D concealing the repellent substance C. Adjustment is performed by one or more elution adjustment means among the adjustment means.

  FIGS. 13-1 to 13-9 are schematic diagrams using a specific inorganic acid that is the repellent substance E of the present invention that prevents the shellfish Y attached to the hull 2 (with permeability) from attaching. FIG. 13A shows a hull 2 (a marine object such as a stone or a submarine object). FIG. 13-2 intends to prevent the reproduction of the shellfish Y on the hull 2, and the repellent substance E for the shellfish Y is applied to the entire hull 2 on land. After the application, the applied repellent substance E penetrates into the hull 2 as time elapses. This infiltration state is shown in FIGS. 13-3 to 13-4. FIG. 13-3 shows a state in which the repellent substance E is infiltrated, and FIG. 13-4 shows an infiltration state of the repellent substance E. It is in a state. Thereafter, the permeated repellent substance E is concealed with a porous paint F such as a porous polyamide resin paint and / or a porous polymer paint. Therefore, even if the hull 2 is washed with seawater, the repellent substance E is unlikely to diffuse rapidly under these conditions, and is effective because it is eluted and gradually released through the porous body of the porous paint F. continue. Even in a situation where the shellfish Y competes against the hull 2 while the required time has passed, the shellfish Y reacts instantaneously to the repellent substance E (the repellent effect is Yes, there are multiple things to avoid (not shown), and several things that are shown as an example to suppress reproduction. The repellent applied in this way is the situation before the growth was suppressed by contact with the shellfish Y and / or penetration (erosion) into the outer shell (shell), etc. (FIG. 13-5). The grown ones can observe the action of the limb Y1 of the shellfish Y as shown. However, as shown in FIGS. 13-6 and 13-7, this reproduction is temporary, and after a few days, the applied repellent E acts and the action of the limb Y1 of the shellfish Y And the extremity Y1 is killed or deflated, and the shellfish Y is separated from the hull 2. Thereafter, as shown in FIGS. 13-8, all shellfish Y are peeled off, and the peeled dead shellfish Y is separated from the hull 2 and retreats from the seabed. FIG. 13-9 shows the situation after the shellfish Y is peeled off. For example, the surface of the hull 2 containing the repellent substance E is visible. The hull 2 is in an initial state without the attachment of shellfish Y. Then, after a few years, the repellent substance E fades away and, for example, the surface of the hull 2 can be visually observed. And in this invention, since the specific inorganic acid which is the repellent substance E is eluted and sustained-released from the porous coating material F over time, it is a test result mentioned later that at least this state continues for one year to several years. It was confirmed by. The length of the elution time (long and short of repellent effect) consists of adjusting the penetration depth of the repellent substance E, adjusting the amount of the repellent substance E to be permeated, and adjusting the coating amount of the porous paint F concealing the repellent substance E. Adjustment is performed by one or more elution adjustment means among the adjustment means.

A third example will be described.
14-1 to 14-9 are a specific algae that is the repellent G of the present invention, the repellent H of the algae and the porous paint, and the seaweed X adhering to the block 1. It is a schematic diagram explaining regarding the relationship. 15-1 to 15-9 are schematic diagrams for explaining the relationship between a specific inorganic acid which is the repellent substance I of the present invention, the inorganic acid and the porous paint, and the shellfish Y adhering to the hull 2. It is.

  FIGS. 14-1 to 14-9 are schematic diagrams using the seaweed X adhering to the block 1 using a specific algae that is the repellent G of the present invention, and a repellent H composed of the repellent G and a porous paint. FIG. 14A shows a block 1 (a marine object such as a stone or a submarine object). From FIG. 14-2, it is intended to prevent the reproduction of the seaweed X to the block 1, and the repellent H composed of the seaweed repellent substance G, the repellent substance G, and the porous paint is added to the entire block 1. Apply on land sequentially after a while. In these application states, the repellent substance G is applied, and when the repellent substance G penetrates and is dried, the repellent H (consisting of the repellent substance G and the porous paint) is applied to the entire block 1. This characteristic (repellent property / sustainability of repellent H and protective property / sustainability of porous paint, etc.) can be maximized. Then, after the application, after a lapse of time, the applied repellent substance G penetrates into the block 1, and the surface of the block 1 is concealed with the repellent H composed of the repellent substance G and the porous paint. . This state of penetration and concealment is shown in FIGS. 14-3 to 14-4. FIG. 14-3 shows the state of penetration, and FIG. Is concealed by a repellent G and a repellent H composed of a porous paint. Therefore, even if the block 1 is washed with seawater, the repellent substance G is concealed by the repellent H composed of the repellent substance G and the porous paint. Elution and sustained release (elution from the inside to the surface and / or sustained release) through the porosity of the material maintains its efficacy. And even if the spore X1 of the seaweed X has floated toward the block 1 in the state where the required time has passed as shown in FIG. 14-5, the spore X1 contains the repellent substance G in the spore X1. There are a plurality of things that react instantaneously (having a repellent effect) and repel (not shown), and a plurality of things that are repressed to a certain extent (resulting in death) as shown as an example. Further, in the configuration example in which the porous coating material has easy slipperiness, adhesion of the spore X1 can be prevented as much as possible. However, as shown in FIG. 14-6, a small number of spores X1 passing through the repellent substance G may be regenerated and become seaweed X. However, the applied repellent substance G is the repellent substance G and the porous substance. Since it passes through the repellent H made of a water-soluble paint and is gradually released toward the surface of the block 1, it invades into the living body of the seaweed X that reproduces in the block 1, and erodes and grows the seaweed X In this example, three locations (three stocks) were shown. As shown in the figure, the grown one can observe the growth of the stem X3 and / or the leaf body X4. However, as shown in FIG. 14-7, this reproduction is temporary, and after a few days, the repellent substance G that has been eluted and released gradually acts, and the action of the root X2 of the seaweed X And the stem X3 and / or the leaf body X4 is depleted or attenuated, and a part of the stem X3 falls off due to a decline in reproductive function. In this example, it is in the state where about 2 shares were peeled off. After that, after several days as shown in FIG. 14-8, all three strains are peeled off by the same reasoning as described above, and the already dried dead seaweed X is separated from the block 1 It is floating in the sea. 14-9 shows the situation after the seaweed X is peeled off. For example, the surface of the block 1 with the repellent H is visible. The block 1 is in an initial state without adhesion of seaweed X, and its surface is concealed with a porous paint. Then, after several years, the repellent H fades away and, for example, the surface of the block 1 becomes visible. In the present invention, since the repellent substance G is eluted and gradually released from the porous paint over time, it was confirmed from the test results described later that at least this state continues for one year to several years. The repellent H is created by stirring and mixing a specific algae that is the repellent G and a porous paint at an appropriate mixing ratio. The mixing ratio is not limited. For example, the mixing ratio is adjusted according to the length of elution time (long or short of repelling effect), the amount of reproduction, and the like. The length of the elution time of the repellent substance G is adjusted by adjusting the penetration depth of the repellent substance G, adjusting the amount of the repellent substance G to penetrate, adjusting the application amount of the porous paint of the repellent H that conceals the repellent substance G, Adjustment is performed by any one or more elution adjustment means among elution adjustment means including adjustment of the mixing ratio of the repellent substance G of the repellent H that conceals the repellent substance G.

  FIGS. 15-1 to 15-9 show that the shellfish Y attached to the hull 2 (wood, hull 2 made of porous resin or the like or hull 2 provided with a porous body) is the repellent substance I of the present invention. 15-1 is a schematic diagram using a repellent J composed of an inorganic acid and a repellent substance I and a porous paint. FIG. From FIG. 15-2, it is intended to prevent the reproduction of the shellfish Y to the hull 2, and the entire hull 2 includes a specific inorganic acid / repellent material I and a porous paint, which are repellent materials I for shellfish. The repellent J is applied on land one after another (in the dry process). This repellent substance I and repellent J exert a repellent effect on the shellfish Y adhering to the hull 2. That is, as time elapses after this application, the applied repellent substance I and / or repellent J comprising the repellent substance I and the porous paint penetrates into the hull 2. This state of permeation is shown in FIGS. 15-3 to 15-4. FIG. 15-3 shows the state of permeation, and FIG. 15-4 shows the state of permeation. The surface of the hull 2 is in a state of being concealed with a repellent J comprising repellent substance I and porous paint. Therefore, even if the hull 2 is washed with seawater, it is concealed by the repellent J composed of the repellent substance I and the porous paint, so that the repellent substance I cannot be diffused rapidly, and elution / slow Since it is released, characteristics such as repelling characteristics and sustainability similar to those of the examples of FIGS. 14-1 to 14-9 can be exhibited. And even in the situation where the shellfish Y competes against the hull 2 while the required time has passed, the shellfish Y reacts instantaneously to the repellent substance I (the repellent effect is Yes, there are multiple things to avoid (not shown), and several things that are shown as an example to suppress reproduction. The repellent substance I applied in this way is in a state before the growth is suppressed by contacting the shellfish Y and / or penetrating into the outer shell (shell), and in this example, two are attached. The grown ones can observe the action of the limb Y1 of the shellfish Y as shown. However, as shown in FIGS. 15-6 and 15-7, this reproduction is temporary, and after a few days, the applied repellent substance I acts through the porous paint, The action of the limb Y1 of the shellfish Y is suppressed, and the limb Y1 is killed or deflated, so that the shellfish Y is separated from the hull 2. Thereafter, as shown in FIGS. 15-8, all the shellfish Y are peeled off, and the peeled dead shellfish Y is separated from the hull 2 and retreats from the seabed. 15-9 shows the situation after the shellfish Y is peeled off. For example, the surface of the hull 2 with the repellent J is visible. The hull 2 is in an initial state without the attachment of shellfish Y. Moreover, although the surface is concealed with the porous coating material, after several years, the repellent J fades away, and, for example, the surface of the hull 2 becomes visible. In the present invention, since the inorganic acid (repellent substance I) is eluted and gradually released from the porous paint over time, it can be confirmed from the test results described later that at least this state continues for one year to several years. It was. The repellent J is created by stirring and mixing the repellent substance I and the porous paint at an appropriate mixing ratio. The mixing ratio is not limited. For example, the mixing ratio is adjusted according to the length of elution time (long or short of repelling effect), the amount of reproduction, and the like. The elution time of repellent substance I is adjusted by adjusting the penetration depth of repellent substance I, adjusting the amount of repellent substance I permeating, adjusting the amount of repellent J porous coating applied to hide repellent substance I, Adjustment is performed by any one or more elution adjustment means among elution adjustment means consisting of adjustment of the mixing ratio of the repellent substance I to the repellent J which conceals the repellent substance I.

  FIG. 3 shows a list of porous paints and repellent substances used in the test of the present invention and the presence or absence of the repellent effect of FIGS. 4 to 10-2. FIGS. 4 to 10-2 are tables (diagrams) showing the results of the sea test shown in FIGS. 1-1 to 2-7 and FIG. Based on these materials, the superiority or inferiority of the features of the present invention will be described below. In addition, it demonstrates as an example the result of having tested in the place which divided the underwater for the test (it was set as the test areas 1-10).

  In the attached weight after 6 to 12 months shown in FIG. 3, the repellent of seaweed (plant) is “trade name Hopzin IR (algaeproofing agent)” in Test Zone 1 and in Test Zone 3 "Pelargonic acid (fatty acid)", "Nicotine (organic substance)" in test section 6, "Natrium chloride (base)" in test section 8, and "Trade name fucodyne (organic substance)" in test section 10 were effective. It was. As a guide, it is shown as the weight attached (total weight attached to the block 1) in the chart of FIG. 4 and the bar graph of FIG. That is, the numerical values of the test sections 1, 3, 6, 8, and 10 are subsided at about 0.29 to 3.00 g after 12 months and are considered to be sufficiently effective. This result shows a low numerical value even with the adhesion weight shown in FIG. 4, and also appears low in the bar graph display of FIG. After observing the effective repellent effect on seaweeds, it was a period of about 12 months, but a continuous repellent effect was confirmed.

  3 to 12 months, the repellents of shellfish (animals) are “trade name undecyl acid (fatty acid)” in test section 2 and “trade name sulfamic acid in test section 4”. (Inorganic acid) ”,“ trade name nicotinamide (organic substance) ”in test section 5,“ nicotine (organic substance) ”in test section 6,“ sodium hydroxide (base) ”in test section 7, “Natrium chloride (base)” in section 8, “alginic acid (organic substance)” in test section 9, and “trade name fucodyne (organic substance)” in test section 10 were effective. As a rule of thumb, it is shown as the number of attachments in FIGS. 6-1 to 6-3 and FIGS. 7 and 8, that is, in the test sections 2, 4, 5, 6, 7, 8, 9, 10. After 12 months, the range of 133 to 326 on the side of the lower draft in FIG. 6-1, the range of 13 to 131 on the outer surface of the bottom of FIG. Overall, the range is from 148 to 378, which is considered to be sufficiently effective. After observing the effective repellent effect on shellfish, it was a period of about 12 months, but a continuous repellent effect was confirmed. The line graph shows that “sulfamic acid (inorganic acid)” in test section 4 of FIGS. 7 and 8 is most effective.

  3 and 12 months later, the repellents of shellfish (animals) are “trade name undecyl acid (fatty acid)” in test section 2 and “trade name sulfamic acid in test section 4”. (Inorganic acid) "," trade name nicotinic acid amide (organic substance) "in test section 5," nicotine (organic substance) "in test section 6, and" sodium hydroxide (base) "in test section 7: "Natrium chloride (base)" in test group 8, "alginic acid (organic substance)" in test group 9, and "trade name fucodyne (organic substance)" in test group 10 were effective. As a tentative guide, the adhesion weight is shown in FIGS. 9-1 to 9-3 and FIGS. 10-1 and 10-2, that is, the test sections 2, 4, 5, 6, 7, 8, 9・ After 10 months, the value of 10 is in the range of 6.65 to 25.74 g (excluding some) on the side of the draft in FIG. 9-1, and 0 on the outer surface of the bottom of FIG. 9-2. It is in the range of 0.08 to 3.68 g, and in FIG. 9-3 as a whole, it is settled in the range of 7.68 to 25.85 g, which is considered to be sufficiently effective. In addition, the chart (Figure) shows that the corresponding test plots in FIGS. 10-1 and 10-2 are effective. In this example, the effective repellent effect on the shellfish Y by adopting the organic repellent B was observed, which was a period of about 12 months, but a continuous repellent effect could be confirmed. The bar graph shows that “sulfamic acid (inorganic acid)” in the test section 4 of FIGS. 7 and 8 is most effective.

FIGS. 11A to 11C illustrate the relationship between the repellent substances and the continuous pores (bubbles) of the porous polyamide resin paint and porous polymer paint exemplified in the second example. . In FIG. 11-1, a repellent was applied to the specimen, and the specimen was covered with a porous polyamide resin paint, and the elution degree in water was examined. As shown in the figure, the mixing ratio of the porous polyamide resin paint was shown as 5 wt%, 10 wt%, and 15 wt%. And although it is a little difference, when the degree of elution was tested over the 1st to 7th days, the mixing ratio was 5% by weight, and the dissolution rate was higher than 15% by weight. Has been. The difference in pH value at 5%, 10%, and 15% by weight of the mixing ratio suggests that the elution time of the repellent substance can be adjusted by adjusting the mixing ratio. Further, in FIG. 11-2, a repellent substance was applied to the specimen, and coated with “Nanocoat (trade name)” which is an example of a porous polymer paint, and the elution degree in water was examined. As shown in the figure, the mixing ratio of the polymer coating F is shown as 50 g / m ² , 70 g / m ² , and 100 g / m ² . Then, it is closely, treatment was tested degree of elution over a 1 day to 7 days, the percentage of it is dissolved from 100 g / m ² of the mixing ratio is 50 g / m ² is a number, the result is pH numeric Is displayed. When the mixing ratio is 50 g / m ² , 70 g / m ² , or 100 g / m ² , the difference in pH value suggests that the elution time of the repellent substance can be adjusted by adjusting the mixing ratio. Furthermore, in FIG. 11-3, a repellent substance was apply | coated to the test piece, and it coat | covered with "Terios coat (brand name)" which is an example of a porous polymer coating material, and examined the elution degree in water. As shown in the figure, the mixing ratio of the polymer paint was shown as 50 g / m ² , 70 g / m ² , and 100 g / m ² . Then, it is closely, treatment was tested degree of elution over a 1 day to 7 days, the percentage of it is dissolved from 100 g / m ² of the mixing ratio is 50 g / m ² is a number, the result is pH numeric Is displayed. When the mixing ratio is 50 g / m ² , 70 g / m ² , or 100 g / m ² , the difference in pH value suggests that the elution time of the base agent can be achieved by adjusting the mixing ratio.

  Porous polyamide resin paint has weather resistance and is useful, for example, because it can be used in shallow places in seawater and in water tanks (for business use, household use, etc.), ponds, rivers, etc. It is. And in this invention, since the repellent effect of a repellent substance can be ensured for a long term, it has the characteristics, such as being useful, being economical, and providing convenience. Furthermore, there are characteristics such as being useful for environmental protection in the case of specific anti-algae and inorganic acid among repellents.

  In order to demonstrate the repellent effect, it has been found from the test results that the color is also related. An example of this will be described. White, green and black paints are applied to the base of the block 1 or the hull 2 on land. After applying, the treatment according to each of the above-mentioned inventions (Claims 1 to 6) is similarly performed, and the results of testing in the sea show that there is a difference in the repellent effect on this seaweed X etc. (plant) and shellfish Y (animal) I found out. That is, in an example employing white, green, and black (selected based on the judgment that the heat absorption is high and the repellent effect can be expected), there is a higher repellent effect in the test section where the black porous paint was applied. It was. The reason for this is considered to be a synergistic effect between the high absorption of heat by this black color and the repellent effect of this repellent substance.
