DETAILED DESCRIPTION OF THE INVENTION The present invention provides various inconveniences when fishing nets, that is, fishing nets and ropes for aquaculture (hereinafter simply referred to as fishing nets and ropes) become dirty due to adhesion of algae and shellfish in the sea. However, in view of the fact that many of the techniques that have been proposed as means for preventing this phenomenon are unsatisfactory, the present invention aims to eliminate the shortcomings of the conventional means and provide an excellent product that satisfies the users. be. To explain this in more detail, in the past, fishing nets and ropes were coated with metals such as copper and tin in some way as a means of preventing (antifouling) the adhesion of algae, oysters, barnacles, and other shellfish to fishing nets and ropes. Measures have been taken to prevent fouling by causing metal ions to adhere to the seawater, or to coat fishing nets and ropes with paints mixed with various poisons and to dissolve them to prevent fouling. It is having an effect. but,
Both the use of metals and the application of poisonous substances lack sustainability, and the antifouling effect wears off in a short period of time, and algae and shellfish begin to attach, so it is sometimes necessary to pull up fishing nets and ropes to remove algae and shellfish. In addition, if the timing of removal is delayed, the flow of seawater will deteriorate in the case of fixed nets, creating an emergency situation of oxygen deficiency within the fishing nets, which will lead to large losses, so it is difficult to maintain sustainability. Some antifouling means are highly desired. The present invention has an extremely long-lasting antifouling effect and has succeeded in achieving a large effect with a small amount of metal.

(Prior Art) Fishing nets and ropes have traditionally been coated with various antifouling agents or made from materials in which extremely thin copper wire is mixed into the fishing net thread. However, the former type of paint has no antifouling effect unless the drug dissolves in seawater, so the paint itself must be soluble, making it difficult to maintain it for more than six months. In the latter type, the metal wires are easily cut and there is a risk of injury to hands, etc., and the fishing nets and ropes are heavy, making them inconvenient to handle. Apart from these, there is also a method of applying paint mixed with metal powder such as copper or tin, but most of the metal powder is buried in the paint and very little contributes to the generation of metal ions, so in practice effect cannot be obtained. There have also been attempts to make fishing nets using synthetic fibers mixed with fine metal particles, but in this case too, most of the particles are buried during maintenance, so the ion generation effect cannot be obtained, and the drawbacks are that they are heavy and that spinning technology is difficult. It had the disadvantage of being bulky and expensive.

(Problems to be Solved by the Present Invention) As mentioned above, there are several types of spun dirty fishing nets and ropes, but since the antifouling effect does not last long,
It is necessary to take the net out of the sea several times a year and remove attached algae and shellfish. In addition, items that have metal powder embedded or kneaded into them,
Since the number of metal powders that emit metal ions is extremely small, it becomes unnecessarily heavy and has no practical effect. Those that use thin metal wires are also less effective,
There is a problem that the cost is high. Conversely,
The problem is that there is still no one that is easy to produce, has long-lasting effects, is low cost, lightweight, and convenient to handle.

Another serious problem has recently come to the fore. Among the various metals and chemicals used to make fishing nets and ropes antifouling, some are extremely toxic, creating a situation that cannot be overlooked from a health and hygiene perspective. For example, there are reports of a sudden increase in malformations in fish caused by tin compounds and toxic drugs such as tributyltin oxide, and there is a need to use safer substances.

The above-mentioned primer material is made into a liquid like an ordinary paint, and is applied to fishing nets and ropes with a brush or spray. The undercoating material itself may be of any type as long as it is resistant to freshwater or seawater and has a suitable adhesion to fishing nets or ropes, and can be of any type, such as oil-based or solvent-based. This property is determined by the resin and solvent that make up the primer material, so the selection is important.

When the above-mentioned primer material is applied to fishing nets and ropes,
Since a film is formed covering the entire surface, it is difficult to peel off, and there is no need to consider the adhesion as strictly as compared to an undercoat material when metal is thermally sprayed onto a flat surface.

The preferred method for metal spraying is so-called low-temperature spraying; high-temperature spraying risks weakening fishing nets and ropes or causing them to catch fire. In low-temperature thermal spraying, the temperature of the sprayed metal particles is as low as 25 degrees Celsius when they adhere to the object, so they do not have any adverse effects on fishing nets or ropes.

(Function) As shown in FIG. 1, the fishing net or rope of the present invention is characterized by having a thin layer 6' of fine metal particles formed by thermally spraying copper or a copper alloy on its surface. Normally, it is impossible to spray metal onto fishing nets or ropes made of natural or synthetic fibers, but the present invention has made this possible, and the reason for this is explained with reference to Figures 2 and 3. By applying an undercoat material made of the coating material 5 mixed with ceramic particles 4 to the surface of the thread 1 constituting the fishing net, a film 2 is formed when the coating material dries. When this film is enlarged, it is formed by randomly laminating metal powder or ceramic particles 4 adhered to the coating material 5, often in a pyramid shape, and the shape varies depending on the mixing ratio of the coating material and particles. Although it is different, it is adhered to the legs 3 and knots 7 of the fishing net in the state shown in FIG. Alternatively, it will be physically strongly bonded to the ceramic particles 4. Moreover, since the metal or ceramic particles 4 themselves are fixed onto the fishing net by the coating material 5, the sprayed metal particles 6 are eventually firmly fixed onto the fishing net, forming a thin metal layer 6'.

Now, as is well known, the thermally sprayed copper particles 6 have a very complicated shape and are usually said to be dendritic, but their surface area is extremely large. Furthermore, as shown in FIG. 4, the surface 6a of the thin metal layer 6' is in such a shape that the entire surface is in contact with the outside world without being blocked by anything else, so when such a fishing net A is put into the sea, a large amount of Copper ions are generated, and the antifouling effect is tremendous.
