Description

The present invention relates to a ship bottom paint for preventing shellfish such as Fuji oysters and oysters from adhering to the ship bottom, and a method for manufacturing the same. Although there are many types of Fuji and oysters, sticking to the bottom of the ship increases water resistance, lowering the speed of the ship and reducing fuel consumption.
However, since conventional ship bottom paints have added toxic repellents such as inptyl acetate, xylene, and lead components, they have had an impact on marine pollution and marine ecosystems.

The inventor of the present application, as disclosed in Japanese Patent Laid-Open No. 6-80908, mixed a liquid obtained by applying a quail potato with a juicer mixer in a ratio of 5 or 3 to the marine paint 10, and applied it to a metal plate for an underwater experiment. As a result, it was possible to achieve a good result that even one 15 months passed, no one Fuji moth was attached.
JP-A-6-80908

The “Kuwazu-imo” is a Japanese name, which is called “Ego-Mam”, “Egon-mu”, “Hachikon-mu”, “Nambashi”, etc. in the Okinawa dialect, and its scientific name is “Alocasia Odora Spach”. It is distributed from southern Shikoku to northern India. In Okinawa, it grows naturally under trees.

When this kuwa-imo was pulverized with a juicer mixer, mixed with paint (paint), and coated on a test piece, the repellent effect of Fuji-an was confirmed. The technique of mixing with the paint as it is is not necessarily effective in terms of paintability. Smooth mixing of mulberry crushed liquid and paint is difficult, poor adhesion to the bottom of the ship, and easy to peel off or fade in a short time. Also, painting is not easy.
In other words, if you mix water-soluble pulverized liquid made with a juicer mixer and oil-based ship bottom paint and apply to the bottom of the ship, the oily part and the part that is not compatible with oil tend to separate, and the part that is not compatible with oil in seawater It will melt out. Since the part that is not familiar with this oil contains Kuwa-zuimo's Fuji repellent component, the repellent effect as a ship bottom paint may be reduced. In addition, it seems that the reason why the coating property is poor is that the viscosity as a paint is also hindered.

The technical problem of the present invention is to pay attention to such a problem, and to be able to effectively mix the mulberry potato, which is excellent in the repellent effect of shellfish such as Fuji Pass, with the ship bottom paint, and to be able to be effectively applied to the ship bottom. is there.

The technical problem of the present invention is solved by the following means. The first aspect of the present invention is a ship bottom paint obtained by mixing dry powder of mulberry potato with a paint.
Thus, when the dried powder of mulberry is mixed with non-repellent or non-toxic paint and applied to the bottom of the ship as a bottom paint, it is clear from the test results in Table 1. It can fully demonstrate the repellent effect of Fuji oysters and oysters and is promising as a ship bottom paint. In particular, it does not contain harmful substances that pollute seawater, and there is no fear of marine pollution.
In addition, since the toxicity of mulberry is a plant-derived organic substance, it is decomposed by microorganisms in the sea and eventually disappears.

Claim 2 is the ship bottom paint according to claim 1, wherein the dry powder of mulberry is mixed at a ratio of 2.5% to 0.5% with respect to 100% of the paint. .
Thus, when the above-mentioned dry powder of mulberry is mixed at a rate of 2.5% to 0.5% with respect to 100% of the paint, the results of the test show that the repellent effect of Fuji oysters and oysters is sufficient. Recognized.

Claim 3 is a ship bottom paint according to claim 1 or 2, wherein a dry powder of chili is also mixed.
As described above, when mixing the dried powder of mulberry potato with the paint, mixing with the dried powder of chili pepper in this way also adds stimulation by capsaicin contained in the chili pepper, and is expected to repel shellfish such as Fuji cocoon. it can.

According to a fourth aspect of the present invention, there is provided a method for manufacturing a ship bottom paint, characterized in that a kuwa-imo is dried and powdered and uniformly mixed with the paint.
In order to produce a ship bottom paint containing the dried mulberry dried powder according to claim 1, it is effective to uniformly mix with a paint that does not contain or contain a toxic substance in a state where the dried mulberry is in a dry powder form. It is. When the mulberry potato is made into a dry powder and then mixed with the paint, the quail potato powder does not contain any water, which is likely to increase the affinity with the paint. Therefore, it can be easily applied as a ship bottom paint, has no problems such as peeling or separation, and has a long life.

A fifth aspect of the present invention is the method of manufacturing a ship bottom paint according to claim 4, wherein the pepper is mixed with the paint in a dry powder state.
In order to produce a ship bottom paint mixed with dry powder of chili as in claim 3, the paint is uniform with the paint mixed with dry powder of kuwaimo as in claim 4 in a state where the chili is also dry powdered as described above. According to the method of mixing, since the dried pepper powder does not contain moisture, it is possible to produce a paint having good affinity with the paint and rich in viscosity. It should be noted that either the dried kuwa-imo powder or the dried chili powder may be mixed with the coating material first, or both powders may be mixed with the coating material before mixing with the coating material.

Claim 6 is a shellfish repellent method characterized in that the adhesion of shellfish is prevented by applying to the bottom of the ship a paint prepared by mixing dried powder of mulberry potato or dry powder of chillies and mulberry potato.
In this way, according to the method to prevent the adhesion of shellfish such as Fuji oysters and oysters by applying paint that is mixed with dried powder of mulberry potato or dry powder of mulberry and quail potato, It seems that they can avoid the adhesion to the bottom of the ship. In addition, when it contains dried powder of chili pepper, in addition to the toxicity of quail potato, the irritation peculiar to capsaicin contained in chili pepper is also added, and it seems that shellfish such as Fuji potatoes will not adhere to the bottom of the ship.

When the dried powder of mulberry is mixed with non-toxic or non-toxic paint and applied to the bottom of the ship as a ship bottom paint as in claim 1, it is also apparent from the test results in Table 1. As such, it can fully exhibit the repellent effect of Fuji oysters and oysters and is promising as a ship bottom paint. In particular, it does not contain harmful substances that pollute seawater, and there is no fear of marine pollution.
In addition, since the toxicity of mulberry is a plant-derived organic substance, it is decomposed by microorganisms in the sea and eventually disappears.

When the dry powder of the mulberry is mixed at a ratio of 2.5% to 0.5% with respect to 100% of the paint as in claim 2, the test results show that the repellency of Fuji oysters and oysters is avoided. The effect is fully recognized.

As described above, when the dried powder of mulberry is mixed with the paint, the dry powder of chili pepper is also mixed as described in claim 3 to add the stimulation by capsaicin contained in the chili pepper, thereby avoiding shellfish such as Fuji cocoon. The effect can be expected.

In order to produce a ship bottom paint containing the dried mulberry dried powder according to claim 1, as in claim 4, the mixed powder is uniformly mixed with a paint not containing or containing a poisonous substance in a dried powdered state. Is effective. When the mulberry potato is made into a dry powder and then mixed with the paint, the quail potato powder does not contain any water, which is likely to increase the affinity with the paint. Therefore, it can be easily applied as a ship bottom paint, has no problems such as peeling or separation, and has a long life.

In order to produce a ship bottom paint mixed with a dry powder of chili as in claim 3, the dry powder of kuwa-imo is mixed as in claim 4 with the dry powder of chili as in claim 5. According to the method of uniformly mixing with the paint, since the dried chili powder does not contain moisture, it is possible to produce a paint having good affinity with the paint and rich in viscosity.

According to the method for preventing adhesion of shellfish such as Fuji oysters and oysters by applying a paint obtained by mixing dried powder of mulberry potatoes or dry powder of pepper and mulberry potatoes to the ship bottom as in claim 6, I hate the toxicity of, and seems to be able to avoid adhesion to the bottom of the ship. In addition, when it contains dried powder of chili pepper, in addition to the toxicity of mulberry potatoes, the irritation unique to capsaicin contained in the chili pepper is also added, and shellfish such as Fuji cocoon will not adhere to the bottom of the ship.

Next, an embodiment of how the ship bottom paint and the manufacturing method thereof according to the present invention are practically described will be described. FIG. 1 is a flowchart showing a first embodiment of a method for producing a mulberry potato-containing ship bottom paint according to the present invention.
Step S1 is a mulberry potato as a raw material, that is, a rhizome of a quail potato dug out of the ground, which is washed in step S2 to wash off the adhering earth and sand. Subsequently, in step S3, it is sufficiently pulverized by a pulverizing means such as a juicer mixer to obtain a quail potato pulverized liquid. In step S4, when this mulberry crushed liquid is dried by sun drying or another drying method, it remains as a powder as in step S5.

In step S6, the mulberry moss powder is mixed with a non-toxic paint that pollutes the ocean, thereby completing the bottling powder-containing ship bottom paint in step S7. As a result of borrowing an acquaintance's ship and applying this bottom paint to the bottom of the ship and testing the efficacy, it was confirmed that it has the effect of preventing the adhesion of Fuji oysters and oysters as shown in Table 1.
Table 1 shows a blending ratio of a repellent-containing paint called “Tatsumi” manufactured by Sakai Co., Ltd. and a dried mulberry dried powder (the blended quantity (g) and blended ratio (%) of the dried mulberry dried powder with respect to 100 g of paint)), It is the result of actually applying each ship bottom paint to the ship bottom and testing the efficacy.

As is apparent from the results in Table 1, when 100 g of paint is used as a ship bottom paint by blending 2.50 g (2.5%) to 1.00 g (1.0%) of quail dried powder, Even after months, Fuji oysters and oysters were not attached at all, so they are marked with a good mark. Therefore, it can be said that the mixing ratio is optimum. On the other hand, when 0.50 g (0.5%) of Kuwazuimo dry powder was blended with 100 g of paint and used as a ship bottom paint, the adhesion of Fuji oysters and oysters was confirmed from the 12th month. △ mark indicating that there is an effect to some extent.

In the case of ship bottom paint blended with 0.33 g (0.33%) of dried mulberry powder and ship bottom paint blended with 0.25 g (0.25%), it was confirmed that the fried rice was attached in 6 months. Judging from practical use, it is marked with ▲. In the case where the blending amount of Kuwazuimo dry powder is 0.20 g (0.2%) and when it is not blended at all, the adhesion of Fuji oysters and oysters was confirmed in the third month. , X mark is attached.
In this way, the paint used in the test contains a repellent, but the attachment of Fuji oysters and oysters in the third month seems to be a paint with a weak repellent effect or very little repellent. It is. Therefore, it can be said that the repellent effect of Kuwazuimo dry powder is sufficient.
On the contrary, when 5g (5.0%) or more of the dried mulberry powder was blended, Fuji moths and oysters did not adhere at all even after 15 months and the repellent effect was high. Since the blending amount is too large, it is difficult to apply the brush with a rough texture, so it is not suitable as a ship bottom paint. Therefore, it is marked with *.

As described above, when the kuwaimo dried powder was blended at a ratio of 2.5% to 1.0% with respect to the amount of paint (100%), the repellent effect for at least 15 months could be confirmed. Further, when 0.5% was added, there was a repellent effect for 12 months, so it could be judged that there was a temporary effect.
As described above, the dried powder of mulberry potatoes was found to have a repellent effect on shellfish such as Fuji oysters and oysters, but its toxicity is calcium oxalate and dioscholine, which is an organic matter, so it is a microorganism in seawater. As it is decomposed and eventually disappears, the impact of marine pollution is extremely small.

In addition to dry powder of kuwaimo, we also tried dry powder of pepper that can be easily cultivated in Okinawa, and confirmed the repellent effect of Fuji oysters and oysters as well as dry powder of kuwaimo.
As shown in FIG. 2, the manufacturing method prepares peppers (fruits) collected in step S1. Red ripe fruits are suitable, but the pungent component of capsaicin is sufficient even if it shows a green color before ripeness.

Subsequently, although it dries in step S2, it may be sun drying or mechanical drying.
When it is sufficiently dried, it is pulverized by a pulverizing means such as a juicer mixer in step S3, and becomes a dry powder of chili as in step S4. When this dry powder of chili is mixed with a paint having no toxicity in step S5, the ship bottom paint in step S6 is completed.

As a result of producing various ship bottom paints containing dried chili powder thus prepared, applying them to the ship bottom, and testing the efficacy, as shown in Table 1, it was confirmed that the same effect as the ship bottom paint blended with the dried powder of kuwaimo was confirmed.
That is, when 2.50 g to 0.50 g of pepper powder was added to 100 g of the paint, Fuji oysters and oysters did not adhere for 12 to 15 months. Thus, although it was quite a coincidence, the result was exactly the same as the case of using Kuwazu imo fine powder, so the table showing the test results when using pepper fine powder was omitted.

The same repellent effect was confirmed with dry powder of chilli pepper as with dry powder of kuwaimo, so even when both dry powder of chrysanthemum and dry powder of chilli were used together and blended into paint, the repellent effect was also achieved. There seems to be.
In FIG. 1, the raw rhizome of mulberry potato was pulverized and then dried. As in the case of producing the dried pepper powder of FIG. 2, May be finely pulverized into a fine powder. In this case, if it is possible to dry effectively, it is possible to uniformly dry in a shorter time, and to smooth the next pulverization process, if the rhizome of mulberry potato is cut in a circle or cut or crushed into chips. .

As described above, a household juicer mixer was used as a pulverizing means, but it is needless to say that large-scale high-performance equipment for mass production should be prepared when industrializing a large amount of mulberry potatoes and chili peppers. Yes. Mechanical drying may also be used as the drying means.
In addition, the paint used in Table 1 is due to the fact that only a paint containing a conventional repellent was available. In practical use, the conventional repellent was not contained and a conventional chemical was not used. By using a paint with no or little toxicity derived from substances, problems such as marine pollution are prevented as much as possible.

As mentioned above, when the mulberry potato is made into a dry powder and then mixed with the paint and used as a ship bottom paint, the repellent effect of Fuji oysters and oysters has been recognized. Preservation of the global environment is possible by preventing the influence of marine organisms on the ecosystem, and because of its good compatibility with paints, mixing and application to the bottom of the ship will be smooth and expected to spread. Moreover, in recent years when the fuel of ships has soared, the application of the ship bottom paint according to the present invention can prevent the attachment of shellfish and suppress the deterioration of fuel consumption due to an increase in water resistance, so the effect is extremely great.

It is a flowchart which shows embodiment of the manufacturing method of the ship bottom coating material containing a mulberry potato powder by this invention. It is a flowchart which shows embodiment of the manufacturing method of the ship bottom coating material containing the dry powder of chili by this invention.
