Description

[Detailed description of the invention] The present invention relates to an organic polymer composition for bait.

Squid, mackerel, horse mackerel, etc. are currently used as bait for longline fishing. Are fish such as saury and sardines used directly? These baits are unstable in supply and subject to large price fluctuations; freezing is required to preserve these fish; There are various problems such as the installation work is not necessarily efficient. Therefore, various attempts have been made to find inexpensive artificial baits that are easy to install and have a high shelf life, but no one has yet been found that has sufficient functionality as an artificial bait. For example, synthetic resins such as polyvinyl chloride and polyurethane, which are conventionally known as artificial baits. Shino, which is made from a mixture of fibers such as wool and cotton, is extremely hard and feels far from a true fishing bait, and is usually mixed into artificial bait. The attracting effect of the attracting substance could not be sufficiently exhibited. What is required as an artificial bait is one that approximates real fishing bait in terms of strength, flexibility, surface feel, etc., and that can release an attractive substance added as appropriate into the water for a long period of time. The object of the invention is to provide a composition having desirable functions as such a lure.

That is, the present invention relates to an organic polymer composition for bait, which contains a water-soluble organic polymer in a water-insoluble organic polymer.

Examples of the water-insoluble organic polymer of the present invention include resin-like or rubber-like polymers alone or a mixture thereof.

Examples of resinous polymers include polyvinyl chloride, polyvinyl citrate, polymethacrylate, polyvinylidene chloride, polyurethane, polystyrene, and ethylene-vinyl citrate copolymer, and examples of rubbery polymers include nitrile rubber and polychloroprene rubber. , epicchlordrin gum,
Particularly preferred are polar rubbers such as acrylic rubber, chlorinated polyethylene rubber, and chlorosulfonated polyethylene rubber.
Other non-polar rubbers such as natural rubber, isoprene rubber, ethylene-propylene rubber, styrene-acrylonitrile rubber and polybutadiene rubber are used.

Examples of water-soluble organic polymers include polyethylene oxide, polyacrylate, polyacrylamide, polyvinylpyrrolidone, water-soluble cellulose derivatives such as methylcellulose, and carboxylated methylcellulose, water-soluble starch derivatives, polyvinyl alcohol or its derivatives, etc. Any material that is compatible with the water-insoluble organic polymer may be used.

In addition to the above-mentioned polymers, the composition of the present invention may also have any other attracting effects such as fluorescent substances, fish oils, fishy odor chemical substances, etc. It is preferable that the effect as a lure is further enhanced by adding a product to the bait.

Also, strength and flexibility. In order to maintain processability, stability, and other properties as a pseudogroup, the composition of the present invention may further contain a softener and a plasticizer. Compounding agents such as crushing agents, fillers, processing aids, anti-aging agents, and preservatives can be added.

When the bait obtained from the composition of the present invention is dropped into water, it swells and becomes moderately flexible, and the water-soluble polymer gradually leaches out and dissolves on the surface. (Gives the surface of the artificial bait an appropriate level of stickiness and forms an appearance very similar to that of the real bait. In this case, if a substance that attracts fish is mixed in, the water-soluble organic polymer will leach and dissolve.) Along with this, the attractant substance diffuses into the water, making it even more effective as bait.

The rate of leaching of a water-soluble organic polymer in water influences its effectiveness as a bait, and this depends primarily on the molecular weight and content of the water-soluble organic polymer. The preferred range of the water-soluble organic polymer content varies depending on the combination of water-insoluble organic polymers used, and can be determined experimentally. Usually, the amount of the water-soluble organic polymer is suitably in the range of 1 to 70% by weight based on the total amount of the water-insoluble organic polymer and the water-soluble organic polymer.

The attracting substance that can be optionally added to the composition of the present invention can exhibit its effect by adding usually 50% by weight or less based on the total amount of the water-insoluble organic polymer and the water-soluble organic polymer. can. As mentioned above, since the composition of the present invention has a pattern of leaching into water due to the water-soluble organic polymer, the effect is small even if the amount of attractant added is very small.

As a processing method for forming the composition of the present invention into a lure, any commonly used processing means may be employed.

Examples include metal molding, extrusion, blowing, injection molding, and calendering. The composition of the present invention can also be used by coating or laminating a reinforcing material such as a nonwoven fabric or a woven fabric. Further, the molded product may be a crosslinked product or a non-crosslinked product.

The above will be explained using examples.

Example 1 Epichlorohydrin rubber (epichlorohydrin-ethylene oxide copolymer rubber) 100 parts by weight, molecular weight 40
30 parts by weight of polyethylene oxide, 1 part by weight of suderic acid, 10 parts by weight of luminescent material (7ηS type), squid oil (
In order to observe the state of a composition consisting of 10 parts by weight (commercially available) in water, this was extruded at 90°C, and a width of 30
A rectangular sheet with a length of 100 mm and a thickness of 2 mm was produced.

When this sheet was immersed in seawater and the weight increase over time was measured, the weight increase was 2.20 times after 3 hours and 2.8 times after 24 hours.
It has increased five times. After 24 hours had elapsed, the sheet was pulled out of the seawater and observed, and it was found that it had retained its elastic and flexible form and had sufficient strength to hold it even when hung on a fishing hook. It was confirmed that it had a sufficient slimy squid odor and had sufficient effectiveness to be used as an artificial bait.

Example 2 100 parts by weight of polyvinyl chloride for paste, 100 parts by weight of plasticizer (dioctyl phthalate), 1 part by weight of methylcellulose
00 parts by weight, 1.5 parts by weight of tin-based stabilizer, luminescent material (ZnS
A composition consisting of 5 parts by weight of solid fish oil and 5 parts by weight of solid fish oil
Molded in a mold for 5 minutes at 80℃, length 100mm, diameter 30mm.
A cylindrical object with a thickness of 1 mm and a thickness of 1 mm was prepared.

When this was immersed in seawater for 24 hours, the weight increased by 1.
The surface of the fish was 25 times larger and a slimy, fishy odor remained, confirming its continued effectiveness as a lure.

Example 3 100 parts by weight of medium-high nitrile rubber, 50 parts by weight of polyethylene oxide with a molecular weight of 3 million, 1 part by weight of stearic acid, 20 parts by weight of plasticizer (dioctyl phthalate), sodium polyacrylate with a degree of polymerization of 15,000 to 20,000. A composition consisting of 2 parts by weight and 10 parts by weight of fish meal was molded into a fish-shaped molded product with a length of 100 pieces.The state of the fish-shaped molded product 24 hours after it was put into seawater. When observed, the weight increase was 1.88 times, the surface had sufficient sliminess and fishy odor, and the molded product itself had sufficient strength to be used as a lure.
