Description

  The present invention relates to an underwater organism repellent, a paint, and an underwater structure constituted by using at least one of sea urchin or sea urchin shell.

  In recent years, "sea urchin" has been removed as one of the countermeasures against burning. Sea urchins that are removed are often crushed on land or in the sea, but sea urchin shells are sometimes used as organic fertilizers. However, the use of sea urchin shells as organic fertilizer has not progressed significantly due to odor and hygiene problems.

In addition to sea urchins (sea urchin shells) that are removed as part of the measures for burning sea urchin, many sea urchin shells are discarded from general sea urchin processing plants. In Japan, effective utilization of these sea urchin shells has not been found.
In other words, there is an urgent need to find an effective method for utilizing these “sea urchin shells” that are removed and discarded in large quantities in the sea urchin sea area and sea urchin processing plants.

  By the way, various organisms live in the water such as the sea. Among these organisms, barnacles, oysters, blue-necked tigers, blue-tailed seaweeds (hereinafter referred to as “underwater organisms”) grow on the bottom, buoys, harbor facilities, aquaculture nets, stationary nets, etc. It causes various problems.

  For example, when the underwater organisms adhere to the bottom of the ship, the performance (speed, etc.) of the ship is reduced, so that periodic treatment (treatment including removal of underwater organisms) is required for the bottom of the ship. Further, for example, when this underwater organism adheres to and grows in an underwater structure such as a buoy or a harbor facility, the underwater structure itself may be deteriorated. Further, for example, if the underwater organisms adhere to the aquaculture net etc., the durability of the aquaculture net etc. may deteriorate, the underwater adhering organism may block the mesh, and the fluidity of the seawater in the aquaculture net etc. may occur. . Thus, when the fluidity of seawater inside the aquaculture net or the like decreases, it may adversely affect the seafood in the aquaculture net.

  In other words, the adherent growth of attached organisms occurs on the bottom of the ship, aquaculture nets, underwater structures, etc. (hereinafter also referred to as “attached matter”), thereby deteriorating the attached matter itself or removing the attached organisms. Problems such as requiring complicated processing and adversely affecting fish and shellfish in the aquaculture net.

  For such underwater organisms, for example, a technique described in Patent Document 1 is known.

Hereinafter, embodiments of the present invention will be described.
In the present embodiment, the term “sea urchin” means all belonging to the Echinodermata sea urchin class, and other foods such as sea urchin, sea urchin, sea urchin, sea urchin, etc. It is a concept that includes. As a result of intensive studies, it has been found that it is particularly preferable to use “Gangazeuni” in the case of constructing the underwater organism repellent or the like according to this embodiment.
This will be specifically described below.

  The underwater organism repellent according to the present embodiment is configured using sea urchins (sea urchin shells), and here, a case where purple sea urchins and ganga sea urchins are used will be described. Further, as a comparative example, Sazae will be described.

  First, in this embodiment, the following crushed sea urchin shells (first underwater organism repellent M, second underwater organism repellent G) are prepared as an example of underwater organism repellent, and as Comparative Example S A ground tuna shell was prepared.

(1) First water adherent biological repellent M
Sea urchin sea urchin shell (M1: 10g, M2: 30g, M3: 50g)
(2) Second water-borne biological repellent G
Sea urchin shell of sea urchin (G1: 10g, G2: 30g, G3: 50g)
(3) Comparative Example S
Sazae shell (S1: 10g, S2: 30g, S3: 50g)

The first underwater organism repellent M and the second underwater organism repellent G described above are prepared by preparing sea urchin shells (purple sea urchin shells, urchin shell sea urchin shells) from which the contents have been removed and drying them. It is comprised by grind | pulverizing in. The particle diameter of the sea urchin shell after being pulverized is about 0.1 μm to 0.001 mm.
On the other hand, the Sazae husk which is the comparative example S has a very high hardness and is difficult to grind with a mixer. Therefore, in this embodiment, the Sazae shell was crushed with a sander. The grain size of the tuna shell after being pulverized is about 0.1 μm to 0.001 mm.

  Next, in the present embodiment, each of the above-described repellents ((1) to (3)) is mixed with the ship bottom paint (200 g) to form an underwater-attached biological repellent paint (corresponding to the “paint” of the present invention). Configured. In addition, as a comparative example other than the Sazae shell (Comparative Example S), a “ship paint only” one was also prepared. Specifically, it is as follows.

(A) First repellent paint TM (ship bottom paint (200 g) + first underwater biological repellent M)
(Here, the first repellent paint TM is expressed as the first repellent paint TM1 to TM3 according to the amount (M1 to M3) of the first underwater attached biological repellent M).
(B) Second repellent paint TG (ship bottom paint (200 g) + second underwater adhesion biological repellent G)
(Here, the second repellent paint TG is expressed as the second repellent paint TG1 to TG3 in accordance with the amount (G1 to G3) of the second underwater attached biological repellent G.)
(C) First comparative paint TS (ship bottom paint (200 g) + comparative example S)
(Here, the first comparison paint TS is expressed as the first comparison paints TS1 to TS3 according to the amount (S1 to S3) of the comparative example S (crushed Sazae shell).)
(D) Second comparative paint TT (ship bottom paint (200 g) only)

  Known ship bottom paints include hydration-decomposition paints, self-polishing paints, and hydrolysable paints. In the present embodiment, a hydrolytic copolymer antifouling antifouling paint is used as the basic ship bottom paint described above (a ship bottom paint for mixing ground sea urchin shells and the like).

  Next, in the present embodiment, each of the above-described repellent paints ((A) to (D)) is applied to the surface of a material that is substantially the same as the material used to configure the ship bottom to form an underwater structure. did. That is, the underwater structure was configured to confirm the effect of the paint or the like according to the present embodiment.

  Subsequently, the above-mentioned underwater structure was thrown into the sea, and the underwater organisms attached to the surface of the underwater structure were observed. The results are as follows. In this observation result, a case where a relatively large number of underwater organisms such as oysters adhere to the surface of the underwater structure (when about 60% or more of the surface of the underwater structure is observed) is indicated by “x”. When a small amount of oysters or other underwater organisms adhere to the surface of the object (when 10% to 59% of the surface of the underwater structure is observed to adhere) is indicated by “△”, the surface of the underwater structure such as oysters The case where the attached organism is hardly attached (when attachment is recognized on less than about 10% of the surface of the underwater structure) is indicated by “◯”.

  As described above, some effects are also observed for the underwater structure in which the first comparative paint TS is applied to the surface. In addition, it was revealed that the effect of repelling underwater organisms was large in the order of TS1 <TS2 <TS3. However, compared with the second repellent paint TG, there is a great difference in the repellent effect of organisms attached to the water. Specifically, it has been clarified that the second repellent paint TG has a much higher repellent effect on organisms attached to water than the first comparative paint TS.

  Now, since the underwater adhesion biological repellent (the first underwater adhesion biological repellent M, the second underwater adhesion biological repellent G) and the like according to the present embodiment are configured as described above, the following operations are performed. An effect can be obtained. Hereinafter, the configuration, operational effects, and the like will be specifically described.

The underwater organism repellent according to the embodiment of the present invention is characterized by being configured using at least one of sea urchin or sea urchin shell. According to the water-repellent biological repellent configured in this way, by putting this repellent in any place or by applying this repellent to an article, it adheres to the place or the article in water. Biological adhesion can be effectively prevented.
Moreover, it is preferable to use "Gangazeuni" as the sea urchin for this underwater organism repellent. According to this preferable configuration, it is possible to obtain an effect of repelling aquatic organisms for a long time with a smaller amount.

The underwater adhesion biological repellent paint according to the embodiment of the present invention (corresponding to the “paint” of the present invention) is characterized by containing at least one of sea urchin or sea urchin shell. More specifically, this underwater adhered biological repellent paint can be obtained by mixing ground sea urchin shell and the like with ship bottom paint or the like. If it is the underwater adhesion organism repellent paint comprised in this way, based on a comparatively simple manufacturing method and structure, adhesion of underwater adhesion organisms to a ship bottom etc. can be prevented effectively.
Moreover, when this underwater adhesion organism repellent paint is comprised, it is preferable to use "Gangazeuni" as a sea urchin. According to this preferable configuration, it is possible to obtain a paint having an effect of avoiding organisms attached to water for a long time with a smaller coating amount.

An underwater structure according to an embodiment of the present invention includes a composition having at least one of sea urchin or sea urchin shell on at least one of a surface and an inside thereof. More specifically, for example, this underwater structure is constituted by applying a composition having a ground sea urchin shell or the like (such as an underwater biologically repellent paint) on its surface. Further, for example, this underwater structure may be formed by mixing ground sea urchin shells or the like in the forming material and using the forming material. If it is an underwater structure constituted in this way, adhesion of an underwater attachment organism to an underwater structure can be prevented effectively based on a comparatively simple manufacturing method and composition.
Moreover, when this underwater structure is comprised, it is preferable to use "Gangazeuni" as a sea urchin. According to this preferable configuration, it is possible to obtain an underwater structure having an effect of repelling aquatic organisms in a smaller amount for a long period of time.

By the way, it has been clarified that the first comparative paint TS constituted by using the above-described Sazae husk also has an effect of repelling aquatic organisms.
However, this tuna shell has a number of problems that it takes time to dry, it takes time to make a powder because it is hard, and a processing device such as a sander is necessary and difficult to process.

On the other hand, there is no problem as described above with respect to the underwater adhered biological repellent, paint, and the like that are configured using “at least one of sea urchin or sea urchin shell” according to the embodiment of the present invention.
That is, according to this embodiment, since it is a sea urchin, drying time is short and can be easily made into a powder (it is possible with a simple device such as a home food processor). A water-repellent biorepellent and paint can be obtained easily and in a short time.

  Furthermore, when using "Gangazeuni", it has a very large repellent effect even in a small amount as compared with the case using Sazae husk. Therefore, according to this embodiment, by using “Gangazeuni”, it is possible to obtain an underwater-attached biorepellent and an underwater-attached biorepellent paint having very high performance in a short time.

It should be noted that the present invention is not limited to the above-described embodiment, and can be implemented with various modifications as necessary within the scope that can meet the spirit of the present invention. It is included in the technical scope of the invention.

  In the above-described embodiment, the case where the underwater adhered biological repellent is configured by pulverizing the “sea urchin shell” is described, but the present invention is not limited to this configuration. Therefore, for example, without removing the contents of the sea urchin sea urchin, it may be dried as it is, and the dried sea urchin sea urchin itself may be pulverized with a mixer to constitute an underwater organism repellent.

  In the above embodiment, a case has been described in which a sea urchin shell from which the contents have been removed (a sea urchin shell of a sea urchin sea urchin) is prepared, and this is dried and then pulverized by a mixer to constitute an underwater-adherent biological repellent. In this case, the “drying” method is not particularly limited to any method. Therefore, for example, when drying sea urchin shells, sun drying or heating means may be used. In the present invention, when drying the sea urchin shell, a gas stove or a gas burner may be used as the heating means. More specifically, it is preferable to perform the drying process by baking sea urchin shells using a gas stove or a gas burner and heating them to about 1000 degrees.

  Moreover, in the said embodiment, when comprising the underwater structure, the case where the underwater adhesion biological repellent coating material was apply | coated to the surface was demonstrated, but this invention is not limited to this structure. Therefore, for example, the underwater structure may be constituted by using a material containing the underwater adhesion biological repellent by mixing and mixing the underwater adhesion biological repellent in a material such as a resin.

  Furthermore, in the said embodiment, although the structure grind | pulverized after drying a sea urchin shell was demonstrated, this invention is not limited to this structure. Therefore, for example, the sea urchin shell from which the contents have been taken out may be pulverized in an undried state to constitute an underwater organism repellent or the like. In addition, for example, sea urchins (Gangazeuni, etc.) whose contents have not been taken out may be pulverized in an undried state to constitute an underwater organism repellent.

The present invention has been made in order to solve the problems of the prior art (the problem that there is no method for utilizing sea urchin shells and the problem related to underwater organisms).
ADVANTAGE OF THE INVENTION According to this invention, the underwater adhesion biological repellent comprised using at least one of a sea urchin or a sea urchin shell can be obtained. Moreover, according to this invention, the coating material containing at least one of a sea urchin or a sea urchin shell can be obtained. Furthermore, according to this invention, the underwater structure which contains the composition which has at least one of a sea urchin or a sea urchin shell in the surface or at least one inside can be obtained.
That is, according to the present invention, while solving the problems of the prior art, it is possible to obtain an underwater organism repellent, a paint (an underwater organism repellent paint), and an underwater structure that are highly effective in repelling underwater organisms. Can do.
