つある。For this reason, paints have been developed that can be applied to the bottom of ships to prevent these aquatic organisms from adhering to them. However, the effectiveness of these paints in controlling aquatic organisms is not always satisfactory, and in addition, many of these paints contain tin compounds, which may cause depletion in the surrounding area due to their elution and diffusion. Contamination of the ocean and marine life is also being pointed out.
開発を試みた技術的事項
本発明者はこのような背景から、いわゆる無公害で且つ
充分に優れた水生生物の付着防止効果が得られる物質の
開発を試みたものである。Technical matters attempted to be developed Against this background, the present inventor attempted to develop a substance that is so-called non-polluting and has a sufficiently excellent effect of preventing adhesion of aquatic organisms.

みたものである。In other words, as a result of first attempting to investigate the principle of preventing this type of aquatic organisms from adhering, we found that the most likely countermeasures are to use antibacterial properties of substances that aquatic organisms do not try to approach, or to use electrochemical methods using electrical compounds. Based on the knowledge that there may be a clue to solving these problems, we are developing a specific method to obtain a repellent effect by utilizing the properties of adhesion, and to make it difficult to adhere to by improving the properties of the surface to which it is intended to adhere. I tried it.

みたものである。As a result, tannins, which are widely present in the plant kingdom and have antibacterial and bactericidal effects, bind with astringent and water-soluble proteins and become insolubilized, and saponins, which have hemolytic effects, are mucosal irritations, and have poisonous effects on fish. With this in mind, we attempted to develop a material that prevents the adhesion of aquatic organisms using these substances as a substantial protective component.

消泡剤などの補助添加剤を含んだ塗料であってもよい。In the present invention, such tannins or saponins are dispersed in a paint and used as a material for preventing adhesion of aquatic organisms. Vehicles for dispersing tannins or saponins that have been commonly used in the past are used.For example, drying oils, natural resins, synthetic resins, cellulose derivatives, etc. are used as binders, and toluene, xylene, thinners, etc. are used as solvent components. One example is the use of organic solvents. Of course, it may be a binder that does not contain a solvent, or it may be a binder that does not contain a solvent, a pigment, a dispersant, a binder,
The paint may also contain auxiliary additives such as antifoaming agents.

表面に形成されるようにして使用する。A paint containing tannin or saponin as a component is prepared by mixing tannin or saponin with 90 parts of such paint by a conventionally known method, preferably around 10 parts, preferably 1 to several tens of parts. Manufacture. Paints containing such tannins or saponins as ingredients can be applied directly to the object by known coating methods such as applying them directly, or if such paints have been applied to a plate or sheet in advance. These paints can be attached to objects, or even fibers can be impregnated with these paints and fishing nets can be made using the fibers.In short, paints that contain tannins or saponins as part of their components can be used to protect objects. Use it so that it forms on the surface.

か或いは幾つかがなされているものと推察される。Although the principle of operation of the invention has not necessarily been elucidated, when the above-mentioned aquatic organism adhesion prevention material is applied, as will be described in the effect section below, aquatic organisms can avoid adhering to the applied area. This has been confirmed, and as a result, if it contains tannin as an ingredient, it may be due to the bactericidal effect of tannin,
When saponin is included as a component to have one or more of the astringent and water-soluble protein insolubilizing effects, one or more of saponin's hemolytic, mucosal irritating, and toxic effects are also performed. It is presumed that this is the case.

As shown in the drawings, this test method was carried out on an acrylic FRP substrate of appropriate dimensions using the aquatic organisms adhesion prevention material M of the present invention.
was applied in a circular shape with a diameter of 5 cm, and a film length of 3 cm was applied approximately in the center of the circle.
The purpose of this test is to fix a mussel A of m length horizontally and to determine where byssus thread a attaches (plants) to this mussel. Additionally, mussels are typical aquatic organisms used in adhesion tests, along with Fujibbo.
This creature was adopted for the experiment because it easily attaches to marine structures and because it is easy to obtain objective data by counting the number of byssus threads in table tests. The specific method for fixing the mussels is to attach the mussels directly to the central part coated with the anti-adhesion material M, or, as in this experiment, with a piece of rubber about 2 mm thick interposed between the mussels and the mussels with instant adhesive. The byssus was fixed in place, and the byssus was placed in a seawater tank to observe how the byssus threads landed. What this reveals is that if the byssus threads extend beyond the anti-adhesion material M and onto the outer acrylic FRP substrate l, the byssus threads of the purple mussel clearly avoid the anti-adhesion material M. Therefore, it is inferred that the greater the ratio (%) of the byssus threads exposed outside the adhesion prevention material to the number of grown byssus threads, the more the adhesion prevention effect is obtained.

指摘されているものであった。According to this, in Example 1, 92 out of 96 certified threads in sample 1, 34 out of 44 in total in sample 2, and 20 out of 26 in total in sample 3 have a diameter of δem. Byssus threads were extended outside the coated surface, and the average repellency rate was 83%. In addition, in Example 2, both samples 1 and 2.3 died,
It was determined that 100% avoidance was achieved. On the other hand, as a comparative example, in the paint disclosed in JP-A-53-102340 in which powdered oyster shells were mixed into the paint, the average percentage was 28%, and in the paint mixed with chili peppers, the paint was mixed with powdered oyster shells. On average, paints containing no antifouling components (31%) (actually Acrydic A-made by Dainippon Ink and Chemicals
198-XB), the average value was 28%, confirming the remarkable effects of the above two examples. Incidentally, the two reagents cited as comparative examples have already been pointed out as having pesticidal effects in other literature.
