Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire having a pollution preventing function, and more particularly to a wire having a pollution preventing function capable of preventing adhesion of pollutants such as algae and dust used in water.

[0002]

2. Description of the Related Art Generally,
For fishing gear installed in the sea such as cages and seaweed nets,
Contaminants such as algae and dust adhere to nets and ropes, worsening the habitat environment of fish in cages, causing diseases in seaweed, and seaweed from which algae as impurities other than seaweed are harvested There was an inconvenience such as being included in.

For this reason, various proposals have been made to prevent the adhesion of these pollutants, and as a typical example thereof, fine particles or fine powders of photocatalyst such as titanium oxide are contained in resin fibers. A mixed wire is proposed.

However, since the resin skin layer is formed on the surface of the wire and the photocatalyst mixed in the wire is not exposed on the surface, the essential antifouling function is not exerted or is exerted. However, it was insufficient.

The present invention has been made in view of these points, and the function of preventing pollution by an antifouling agent is surely exhibited in water, and by being used as a part of fishing gear, etc., the adhesion of algae and dust is ensured. It is an object of the present invention to provide a wire rod having a pollution prevention function that can prevent the above.

[0006]

In order to achieve the above-mentioned object, a wire rod having a pollution preventing function of the present invention is a resin wire rod containing an antifouling agent for preventing adhesion of contaminants,
The surface is roughened so that the antifouling agent is exposed.

According to the present invention having such a configuration, the antifouling agent exposed on the surface of the resin wire exerts its antifouling function, and the adhesion of contaminants is surely prevented. .

Further, in the present invention, the resin wire is a mixture of polypropylene and polyethylene, and contains 65% by weight or more of the polypropylene and is roughened by burring the surface. Characterize.

According to the present invention thus constructed, a wire made of a resin made of a mixture of polypropylene and polyethylene, in which if the content of polypropylene is 65% by weight or more, the surface of the wire is apt to fray. Therefore, the surface is roughened and the antifouling agent is exposed from the surface, so that the antifouling function is surely exhibited, and the adherence of the pollutant is surely prevented.

In the present invention, as the antifouling agent, one or more of photocatalyst, magnesium oxide, magnesium hydroxide, copper, silver, acidic material, alkaline material, and high concentration sodium chloride may be used. . Since each of these antifouling agents has an excellent antifouling function,
Adherence of contaminants is reliably prevented.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIG.
Will be described.

FIG. 1 shows a wire rod according to one embodiment of the present invention.

In the wire rod 1 of this embodiment, the particulate and / or powdery antifouling agent 3 is mixed and melted in the resin material 2 in the same manner as in the ordinary process for producing resin fibers, and thereafter, It is formed by spinning as a long fiber and then roughening the surface of the fiber to expose the antifouling agent 3 on the surface.

The resin material as the material of the wire 1 may have any composition as long as the surface can be easily roughened. For example, when the wire 3 is made of a mixture of polypropylene and polyethylene and has a composition containing 65% by weight or more of polypropylene, the fibers can be split and the surface can be roughened to roughen the surface. If the polypropylene content is less than 65% by weight, the surface cannot be roughened even if the fibers are split.

As the antifouling agent, any component can be used as long as it can prevent the attachment of contaminants such as algae and dust. Examples of such an antifouling agent include a photocatalyst made of a material known as a material having an antifouling function, magnesium oxide, magnesium hydroxide, copper, silver, an acidic material (for example, sulfonic acid), an alkaline material (for example, , Borax, etc.) and one or more of high-concentration sodium chloride.

Next, examples of the present invention will be described.

Examples 1 and 2 and Comparative Example In Examples 1 and 2 and Comparative Example, polypropylene and polyethylene were 7: 3 as the resin composition of the wire.
Mixing in a weight ratio of 8: 2 and 4: 6, mixing 3 to 20 parts by weight of magnesium oxide having an average particle size of about 2.1 μm as an antifouling agent with respect to the resin, and spinning the fibers to form a wire rod. Created, tested to see if each wire can be split to roughen the surface of the wire, and then each wire is immersed in the sea for 60 days to test the adhesion state of algae and dust. The results are shown in Table 1.

[0018]

[Table 1]

From Table 1, in Examples 1 and 2 in which the mixing weight ratio of polypropylene and polyethylene was 7: 3 and 8: 2, the wire could be sufficiently split, and the surface of the wire was blunted. It has been found that it can be roughened, and as a result, an antifouling agent can be exposed on the surface, which can reliably prevent adhesion of pollutants such as algae.

On the other hand, in the comparative example in which the mixing weight ratio of polypropylene and polyethylene was 4: 6, splitting of the wire could not be performed, and adhesion of algae was observed 10 days after the start of immersion, It was found that the attachment of pollutants cannot be prevented.

[0021]

The wire having the function of preventing pollution of the present invention is
With this structure and function, the antifouling agent exposed on the surface of the resin wire exhibits its antifouling function, and the adhesion of contaminants is reliably prevented. Therefore, by creating a net thread such as a nori net to be installed in the sea using the wire material of the present invention as a raw material, it is possible to reliably prevent the adhesion and propagation of algae other than the seaweed, and to propagate only the seaweed. Since it is possible to reliably prevent the adhesion of dirt and dust, it is possible to reliably prevent the occurrence of nori disease, and it is possible to culture good-quality nori.

Further, in the present invention, the resin constituting the wire is mixed with polypropylene and polyethylene, and the content of polypropylene is 65% by weight or more, so that the surface of the wire is easily rubbed and the surface is prevented from being roughened. The fouling agent is exposed from the surface, the antifouling function is reliably exerted, and the adhesion of contaminants is reliably prevented.

When one or more kinds of photocatalyst, magnesium oxide, magnesium hydroxide, copper, and silver are used as the antifouling agent in the present invention, each of these antifouling agents has an excellent antifouling function. Therefore, the adherence of pollutants is reliably prevented.

The present invention is not limited to the above-described embodiments and examples, but can be modified as necessary.
