More specifically, it relates to molded products such as anti-algae monofilaments, films, sheets, and coating materials that have high corrosion resistance and are non-toxic to fish (and can remain algae-resistant even after being laid for a long time). be.

く、従って１年に４〜５回の組替、洗浄。<Prior art> Fish culture nets and fixed nets, which have become popular in recent years, require immersion of fishing nets in seawater for a long period of time, during which time aquatic organisms such as snails, diatoms, mussels, and Fujibbo are removed. is iS! ii and the ropes that form it, clogging the mesh, resulting in insufficient seawater movement and adversely affecting the survival of fish due to lack of oxygen, etc.
Or it reduces the stickiness of the net. Particularly in yellowtail and yellowtail farming, the fish attach themselves to the fish and suck blood, so the fish have a habit of rubbing it with a fishing net to remove it, but if Fujibushi attaches to the fish during this process, the outer skin is cut, and the area becomes infected with pyogenes. They contracted a purulent disease, which spread further and led to mass deaths. In addition, in fixed nets, increased resistance to ocean currents may lead to poor line formation, and increased weight may cause difficulties in erection and lowering. For this reason, fishing nets are dipped in algaecide containing highly toxic copper compounds or tin compounds to prevent aquatic organisms from adhering to them. However, the algae-preventing effect of such algae-preventing agents only lasts about 2 to 3 months, so they must be replaced and cleaned 4-5 times a year.
乾燥、防藻処理の繰返しである。このための人件費は真
人なものでこれらのことが漁業経営者を圧迫している現
状である。Drying and anti-algae treatments are repeated. The labor costs for this are substantial, and these are putting pressure on fishery managers.

摩耗性等の特性をも考慮し、亜鉛メツキ鋼線製の網生簀
が用いられていた。In addition, as the net for such fish cages, metal net fish cages with good shape retention properties are used.Furthermore, considering properties such as algae resistance, corrosion resistance, and abrasion resistance, mesh fish cages made of galvanized steel wire are used. Net cages were used.

電蝕作用により耐蝕性が低下するという欠点があった。However, although the mesh fish cage made of galvanized steel wire has good shape retention properties against waves, the material itself is exposed due to the sliding movement of the contact parts of the wires, especially the fish cage wire material. If is made of metal,
There was a drawback that corrosion resistance was reduced due to galvanic corrosion.
従って防藻性。Therefore, it is algae resistant.
海水に対する耐蝕性、耐摩耗性の点において今一つ満足

価値の高い高級魚の養殖が盛んに行われている。The corrosion resistance and abrasion resistance of the galvanized steel wire are not satisfactory in terms of corrosion resistance and abrasion resistance.Also, the zinc in the galvanized steel wire dissolves in the seawater, and the residual zinc in farmed fish becomes 2.
It was also found that there were more than twice as many. Also, in recent years, farming of high-grade fish with high added value has been actively carried out.

２〜３日は餌喰いがわるくなり発育の遅れと共に魚病の
原因になっている。又かかる養殖用水槽としてビニルシ
ートのいらないコンクリート製水槽が用いられている。For example, most flounder farming is carried out on land in aquariums. In this case, a wooden or metal panel is used to surround the area and a vinyl sheet is placed on the inside. However, since the vinyl sheet has no algae-preventing effect, it takes about 20 days for the aquarium to grow, such as Kasane Kanzaki, diatoms, Fujibbo, etc. It adheres to the entire surface. In the case of flounder, they have a habit of settling on the bottom, so when they get cut by Fujibbo etc., Pseudomonas enters the cut area and causes a suppurative disease, which spreads and leads to mass mortality. To prevent this, it is necessary to remove the deposits every 10 to 13 days, and each time the fish moves in front of it, it causes stress, which makes it difficult to eat food for 2 to 3 days, slows growth, and causes fish diseases. It has become. Furthermore, concrete aquariums that do not require vinyl sheets are used as aquaculture tanks.
しかしながら上記コンクリート製水槽にも防藻性は全く
ないため、前記木製または金属製パネル水槽と同じよう

になっている。However, since the above-mentioned concrete aquarium also has no algae-proofing properties, it is necessary to remove the deposits every 10 to 13 days, just like the above-mentioned wooden or metal panel aquariums. Moreover, after about three years of use, pathogenic bacteria grow on the surface of concrete aquariums, causing delayed growth and fish diseases.
これらのことが養殖業者の経営を更に圧迫しているのも
また事実である。It is also true that these things are putting even more pressure on the management of fish farmers.

施例を挙げその成果を述べる。Next, there are several methods for producing the molded article of the present invention, for example, as follows. That is, 100 parts by weight of the thermoplastic synthetic resin is mixed with 0.1 to 7.0 parts by weight of sodium propionate or thiabendazole, and the mixture is approximately 180 to 7.0 parts by weight.
Heat and knead at 260°C to give a diameter of about 2.0 to 4. Q m m
The pellets are extruded into a string shape, cooled, and then cut into lengths of about 3 to 4 mm to produce pellets. After heating and kneading this at 180 to 260°C and extruding it into a plate shape, use a calendar roll to obtain a film or sheet of any thickness. I mixed thiabendazole in a proportion of 0.1 to 7.0 parts by weight, heated it to about 180 to 280°C, and made a mold with a diameter of about 1.6 to 4.
．． This is obtained by extrusion coating onto a galvanized steel wire of Q mm. Hereinafter, several examples of the present invention will be given and the results will be described.

It was also found that depending on the time of year, algae could be observed due to the tidal currents, but it quickly dried up and fell off. Furthermore, no deterioration was observed in the exposed portion above the sea surface, and the corrosion resistance and strength properties were also good. In contrast, the comparative wire mesh without additives showed deterioration in the exposed portion above the sea surface.
