Description

Luminous beads for attracting fish {LUMINOUS FOR ATTRACTING FISH}

The present invention relates to luminous beads for attracting fish, and more particularly, to environmentally friendly luminescent beads that do not contain radioactive materials, and which emit light semi-permanently by concentrating light to maintain an afterglow for more than 8 hours, thereby easily attracting fish. will be.

In general, a photoluminescent pigment refers to a pigment having a property of absorbing and accumulating light emitted from almost any light source including sunlight or electric light and then slowly emitting and emitting light in a dark place.

Luminous pigments are additives used in the production of plastics, ceramics, glass, fibers, inks, paints, etc., and are used in transportation, aviation, ships, railways, construction, military, firefighting, and safety industries as well as clothing, shoes, hats, fancy goods, and watches. , toys, stationery and fishing products, etc. are being applied to various industries.

Among them, in fishing supplies, CaS:Bi (violet light emission), CaSrS:Bi (blue light emission), ZnS:Cu (green light emission), ZnCdS:Cu (yellow to orange light emission), etc. By applying the sulfide-based phosphorescent pigment to the float, it is possible to give a function that attracts fish or allows the user to easily check the operation of the float.

However, when the phosphorescent pigment is applied to the fishing float, it takes a lot of time for the phosphorescent pigment to harden, resulting in poor productivity. It is not suitable for use as a light emitting bead to attract fish due to its short time and poor light resistance.

For example, in the case of zinc sulfide-based ZnS:Cu among sulfide-based photoluminescent pigments, when moisture is present, photolysis occurs by ultraviolet rays, turning black or lowering brightness, so direct use in the sea or river where sunlight exists is limited. there is.

As a way to improve this, mixing promethium (Pm), a radioactive material, with photoluminescent pigments can extend the duration of emission, but due to strict handling regulations of radioactive materials in production and disposal, there are many restrictions on use and environmental pollution. There are unavoidable problems.

'High-brightness long-inertia phosphorescent material and manufacturing method thereof (registration number: 10-0329385)' discloses a phosphorescent material in which rare earth elements are added to non-sulfide-based alkaline earth metals. However, there is a problem in that the initial luminance is low and the luminance rapidly decreases after 30 minutes.

In the 'luminous pigment composition with long afterglow time (Registration No.: 10-0598144)', it is prepared by mixing SrAl ₂ O ₄ , which has a light green color, and Sr ₄ Al ₄ O ₂₅ , which has a blue light color, in a 2:1 ratio. A phosphorus photoluminescent pigment composition is disclosed. However, due to mixing only the inorganic phosphorescent pigment, which is alkaline earth metal aluminum oxide, a disadvantage in that it is vulnerable to alkalinity is caused. In addition, research on this is slow, so it is difficult to implement excellent luminescence and long afterglow characteristics, and accordingly, its use as a luminous bead is inevitably limited.

In this way, if the function of the photoluminescent pigment is deteriorated, it cannot be used for a long time, and the light reflection effect is weak in a dark place, in rainy weather, or especially at night, or even if the photoluminescence function is good, it is easily decomposed or oxidized by sunlight, oxygen, and heat over time. Because it peels off and does not fulfill its function, in the end, the light emitting function is lowered and the durability is also lowered.

Therefore, there is a demand for technology development for light-emitting beads that can easily attract fish by having better afterglow than sulfide-type and extending afterglow intensity or afterglow life without adding toxic radioactive materials.

Domestic Patent Registration No. 10-0329385, registered on 2002.03.07. Korean Registered Patent Publication No. 10-0598144, registered on June 30, 2006.

The present invention was invented to solve the above problems, and it is environmentally friendly because it does not contain radioactive materials, and the afterglow is maintained for more than 8 hours to provide a light-emitting bead that can easily attract fish by emitting semi-permanently. as a technical solution.

In order to solve the above technical problem, the present invention is a light-emitting bead connected to a fishing gear to attract fish, including a base resin, 0.01 to 0.03 parts by weight of a fluorescent pigment, and 5 parts by weight of a fluorescent pigment based on 100 parts by weight of the base resin. to 7 parts by weight, and the photoluminescent pigment is aluminum oxide (Al ₂ O ₃ ), strontium oxide (SrO ₃ ) and boron oxide (B ₂ O ₃ ) 2: It is made up of a weight ratio of 2: 1, so that the light-emitting beads accumulate light and then emit light so that the afterglow is maintained for 8 hours or more.

Preferably, the light-emitting beads are characterized in that the highest luminance is 100 mcd/m 2 in a state where the light is blocked after irradiation of light, and the luminance is maintained at 5 mcd/m 2 or more after 8 hours.

Preferably, the fluorescent pigment is characterized in that an orange color series or a green gold color series color is expressed.

According to the present invention by means of solving the above problems, by mixing a base resin and a fluorescent pigment with a phosphorescent pigment composed of aluminum oxide, strontium oxide and boron oxide and molding them into a certain shape, radioactive substances such as promethium or heavy metals are not used. There is an effect of providing light-emitting beads that are harmless to humans and fish.

In addition, the luminescent beads of the present invention can easily attract fish by combining an orange- or gold-green fluorescent pigment having good reactivity or sensitivity to fish and a luminescent pigment having excellent luminous performance, and also improves user visibility. There is an effect that can be increased.

In addition, the phosphorescent pigment of the present invention is easy to mix with the base resin, and can be stably and repeatedly used for a long time by mixing with the base resin, so that the luminescent beads are not deformed from the maximum temperature of 500 ° C to the minimum temperature of -20 ° C. Since it does not occur and has excellent heat resistance and cold resistance, it has excellent durability against various chemical environments or weather changes.

In addition, the luminescent beads of the present invention are not easily decomposed or oxidized by light, oxygen, heat, etc., and can repeat the process of absorbing, accumulating, and emitting light indefinitely, so that the afterglow life lasts for more than 8 hours, and thus has a semi-permanent lifespan. There is an effect that can have.

In addition, biomass such as rice straw, corn cobs, and rice hulls that are not recycled and discarded are powdered and then combined with base resins, fluorescent pigments, phosphorescent pigments, and vegetable oils, thereby reducing the use of petroleum-derived resources and implementing eco-friendly policies. It has a matching effect.

In addition, since excess scrap generated in the process of manufacturing luminescent beads or used luminescent beads can be recovered, ground again into powder form, and then reshaped into luminous beads, the entire amount can be recycled and upcycled. , Accordingly, there is an effect of reducing the production cost of the light-emitting beads.

1 is an exemplary view showing a fishing gear to which the light-emitting beads of the present invention are applied.

Hereinafter, the present invention will be described in detail.

However, the phosphorescent light described in this specification absorbs and accumulates light energy from light or light sources in all areas including natural light and artificial light, converts the accumulated light energy into visible light, and emits light by itself, thereby changing the way the light emitting beads emit light. it means.

In addition, the afterglow means light emitted even after supply of natural light or artificial light to the light emitting beads is stopped.

In addition, the luminance is the degree of brightness per unit area of the light-emitting beads viewed from a certain direction, and means the amount of brightness of the surface of the light-emitting beads.

The present invention relates to a light-emitting bead connected to a fishing gear to attract fish, and the light-emitting bead of the present invention can emit light in a wavelength range of 400 to 600nm so that fish can easily detect it, and includes a base resin and a base resin. It is formed by mixing 0.01 to 0.03 parts by weight of a fluorescent pigment, 5 to 7 parts by weight of a phosphorescent pigment, 0.01 to 0.02 parts by weight of biomass, and 0.01 to 0.03 parts by weight of vegetable oil with respect to 100 parts by weight, and the phosphorescent pigment is aluminum oxide. , Al ₂ O ₃ ), strontium oxide (SrO ₃ ) and boron oxide (B ₂ O ₃ ) in a weight ratio of 2: 2: 1, the light-emitting beads accumulate light and then emit light to create an afterglow It is characterized in that it is maintained for more than 8 hours.

The luminescent beads having these characteristics contain 0.01 to 0.03 parts by weight of a fluorescent pigment, 5 to 7 parts by weight of a phosphorescent pigment, 0.01 to 0.02 parts by weight of biomass, and 0.01 to 0.03 parts by weight of vegetable oil, based on 100 parts by weight of a base resin, at a speed of 1,000 to 3,000 rpm. Viscosity can be adjusted by stirring.

When stirring at less than 1,000 rpm, it is difficult to adjust the appropriate viscosity in the process of mixing base resin, fluorescent pigment, luminescent pigment, biomass and vegetable oil, making it difficult to mold into light-emitting beads, and stirring at a speed exceeding 3,000 rpm In this case, there is a disadvantage in that sample loss occurs due to a pumping phenomenon while the base resin, fluorescent pigment, photoluminescent pigment, and biomass are mixed.

The photoluminescent composition composed of a base resin, a fluorescent pigment, a photoluminescent pigment, biomass and vegetable oil stirred at a speed of 1,000 to 3,000 rpm may have a viscosity in the range of 5,000 to 8,000 cps. When the viscosity of the photoluminescent composition is less than 5,000 cps, the viscosity is too low and the photoluminescent composition resembles a liquid state, making it difficult to mold into light emitting beads. If the viscosity of the photoluminescent composition exceeds 8,000cps, the viscosity is too high and the visibility and photoluminescent performance of the light emitting beads are deteriorated.

Accordingly, the light-emitting beads of the present invention can be stably molded into a predetermined shape by mixing a base resin, a fluorescent pigment, a phosphorescent pigment composed of aluminum oxide, strontium oxide, and boron oxide, biomass, and vegetable oil.

In the present invention, the base resin is composed of a polymer resin that forms a luminous composition together with a fluorescent pigment and a luminescent pigment, and allows the fluorescent pigment and luminescent pigment in powder form to be combined with the base resin to be molded into a luminescent bead having a predetermined shape. is a composition

The base resin excludes the use of aliphatic hydrocarbon resins, aromatic hydrocarbon resins, ester resins, ether resins and ketone resins, and polystyrene (PS), polyethylene (PE), polypropylene (PP), polycarbonate ( At least one kind may be selected from the group consisting of polycarbonate (PC), polyvinyl alcohol (PVA), and polyvinyl chloride (PVC).

In the present invention, the fluorescent pigment improves the visibility of the light-emitting beads, emits an afterglow for a long time when receiving light energy having a certain wavelength ranging from ultraviolet to visible light, and emits light in a dark place after receiving light. , It is a composition that expresses synergistic effects with photoluminescent pigments.

The fluorescent pigment may be a phthalocyanine-based fluorescent pigment that is highly sensitive to fish and exhibits an orange-based or green-gold color-based color that is easy to attract fish.

The fluorescent pigment may be mixed in the range of 0.01 to 0.03 parts by weight based on 100 parts by weight of the base resin. If the fluorescent pigment is less than 0.01 parts by weight, it is difficult to express the color and there is a disadvantage in that a synergistic effect with the phosphorescent pigment cannot be derived. On the other hand, if the fluorescent pigment exceeds 0.03 parts by weight, there is a concern that contamination of the light-emitting beads may occur.

The particle size of the fluorescent pigment may be formed in the range of 3.5 to 4.5 μm. If the particle size of the fluorescent pigment is less than 3.5 μm, the visibility of the light-emitting beads deteriorates, so an amount exceeding 0.03 parts by weight must be added. In this case, the product quality of the light-emitting beads may be deteriorated. If the particle size of the fluorescent pigment exceeds 4.5 μm, it has a disadvantage in that the moldability of the light-emitting beads is deteriorated because the mixing ability with the phosphorescent pigment is not good.

Since the fluorescent pigment is softened at 120 to 200 ° C., it is preferable to set the mold temperature to at least 120 ° C. or higher when molding the photoluminescent composition including the base resin, the fluorescent pigment and the photoluminescent pigment into a mold.

In the present invention, the phosphorescent pigment has a powder form in which light-emitting beads emit light regardless of day and night.

Luminescent pigment absorbs high-energy light from the luminescent beads when light is applied to the luminous beads, and when the light is removed, the absorbed light is slowly re-emitted as low-energy light. let it have

The photoluminescent pigment may be composed of aluminum oxide, strontium oxide having a function of extending the afterglow time, and boron oxide increasing the luminous intensity and luminous duration. Preferably, aluminum oxide, strontium oxide and boron oxide may be mixed in a weight ratio of 2:2:1. By mixing aluminum oxide, strontium oxide, and boron oxide in a weight ratio of 2:2:1, it is possible to prevent decomposition of the base resin while improving the phosphorescent performance of the light-emitting beads. That is, the base resin can be easily decomposed when exposed to sunlight for a long time. Therefore, the base resin is decomposed by adding a photoluminescent pigment in which aluminum oxide, strontium oxide, and boron oxide are mixed in a weight ratio of 2: 2: 1 to the base resin. it is possible to prevent

In addition, the photoluminescent pigment can withstand a temperature of up to 500 ° C and a minimum of -20 ° C, and thus has excellent heat resistance and cold resistance, so that the light emitting beads can have excellent durability against various chemical environments or weather changes.

The particle size of the photoluminescent pigment in powder form is preferably in the range of 5 to 150 μm. If the size of the photoluminescent pigment particle is less than 5 μm, there is a disadvantage in that a satisfactory level of light emission is not achieved due to a decrease in photoluminescence performance and afterglow luminance is also reduced. On the other hand, if the particle size of the photoluminescent pigment exceeds 150 μm, it is difficult to repeatedly absorb, accumulate, and emit light because the irradiation time of a light source such as natural light or artificial light must be increased.

The Mohs hardness of the photoluminescent pigment may range from 6.5 to 7.0. If the Mohs hardness of the phosphorescent pigment powder is less than 6, the abrasion resistance of the luminescent beads cannot be improved and durability is inevitably reduced, and if it exceeds 7.0, mixing power with the fluorescent pigment cannot be obtained.

In such a photoluminescent pigment, it is preferable that less than 0.03% by weight of water is contained in the total weight of the photoluminescent pigment, which is to prevent aggregation of the photoluminescent pigment when mixed and dispersed with a base resin.

In the present invention, biomass can be additionally added, and is composed of sustainable resources produced from water and carbon dioxide by photosynthesis.

Biomass is for adding an eco-friendly aspect by using discarded resources instead of excluding the use of heavy metals or radioactive materials in light emitting beads. Since it is the same as the carbon dioxide absorbed, it has carbon neutral properties that do not increase the concentration of carbon dioxide in the atmosphere in its life cycle.

Such biomass can be obtained from discarded plants, trees, etc., and can be formed in a powder form by pulverizing one or more of rice straw, cornstalks, and rice hulls that have been discarded and not recycled.

Biomass in powder form, such as rice straw, corn cob, and rice hull, may be mixed in an amount of 0.01 to 0.02 parts by weight based on 100 parts by weight of the base resin. If biomass is added in an amount of less than 0.01 parts by weight with respect to 100 parts by weight of the base resin, the bonding force with the base resin cannot be expected, so the eco-friendly aspect is not highlighted. It is not preferable because it may be an obstacle to expression.

In the present invention, the vegetable oil controls the fluidity of the phosphorescent composition so that it can be stably formed into light-emitting beads.

That is, the vegetable oil lowers the mixing viscosity of the photoluminescent composition so that it can be easily molded into a light-emitting bead, and the vegetable oil is one kind from the group consisting of olive oil, camellia oil, jojoba oil, castor oil, almond oil, green tea oil, and argan oil. More can be selected.

Vegetable oil may be mixed in the range of 0.01 to 0.03 parts by weight based on 100 parts by weight of the base resin. If the vegetable oil is less than 0.01 parts by weight, since the viscosity of the photoluminescent composition is lowered, the effect is insignificant, making it difficult to stably form a light-emitting bead. On the other hand, if the vegetable oil exceeds 0.03 parts by weight, the photoluminescent composition becomes excessively slippery, and this also has a disadvantage in that formability is lowered.

As described above, a phosphorescent composition in which 0.01 to 0.03 parts by weight of a fluorescent pigment, 5 to 7 parts by weight of a phosphorescent pigment, 0.01 to 0.02 parts by weight of biomass, and 0.01 to 0.03 parts by weight of vegetable oil are mixed with respect to 100 parts by weight of the base resin is prepared in a certain shape ( For example, in the light-emitting bead 22 manufactured by molding into a sphere), it can be confirmed through FIG. 1 showing a fishing equipment to which the light-emitting bead 22 of the present invention is applied.

1 shows a fishing rig equipped with a light-emitting bead 22 having a phosphorescent performance of the present invention, and the fishing rig is a main line 10 and a branch line connected and installed at predetermined intervals along the longitudinal direction of the main line 10. It may include 20, a fishing hook 21 installed at the end of the branch line 20, and a connector 30 installed on both sides of the main line 10 to connect the weight or main line 10.

In particular, the light-emitting beads 22 of the present invention are connected to branch wires 20 installed at predetermined intervals along the longitudinal direction of the main wire 10. That is, the light-emitting bead 22 is movably installed on the branch line 20, and when the fishing hook 21 is put into the sea, it is moved to a position adjacent to the fishing hook 21, so that the fish detects the light-emitting bead 22 and , There is an advantage in that the fish moving in the direction of the hook 21 can be easily hooked to the hook 21.

In addition, after recovering the excess scrap generated in the process of manufacturing the light-emitting beads 22 or the light-emitting beads 22 that are movably installed on the branch line 20 of the fishing gear and used up, they are crushed and recycled. Since it can be up-cycled in a powder form as much as possible, there is an advantage in securing product competitiveness through reducing the production cost of the light-emitting beads 22.

Hereinafter, an embodiment of the present invention will be described in more detail. However, the following examples are merely illustrative to aid understanding of the present invention, and the scope of the present invention is not limited thereby.

<Test Example 1>

In this test example, after light was irradiated to the light-emitting beads prepared in Examples 1 to 4 and the light-emitting beads prepared in Comparative Examples 1 to 3, the afterglow luminance was measured according to the time when the afterglow was expressed in a state in which the light was blocked. .

In this regard, the light emitting beads molded in Examples 1 to 4 and Comparative Examples 1 to 3 were placed in a box having a size of 50 × 50 × 10 cm to block contact with light for more than 10 hours, and then a D65 standard light source of 200 lux (JIS K5120 ) After irradiation for 20 minutes with an illuminance of 20 minutes, the luminance over time was measured using a TOPCON BM-5 lens in a state where light was blocked, and the results are shown in Table 2 below.

As shown in Table 2, in the afterglow luminance over time, aluminum oxide, strontium oxide, and boron oxide were mixed with a phosphorescent pigment composed of aluminum oxide, strontium oxide, and boron oxide in a weight ratio of 2: 2: 1 along with an orange fluorescent pigment in polyvinyl chloride. It was confirmed that the afterglow luminance value of the luminescent beads according to Example 1 was higher than that of Comparative Examples 1 to 3. Example 2, Example 3, and Example 4 also showed high afterglow luminance values similar to Example 1.

In the initial afterglow luminance, Examples 1 to 4 were 100 mcd/m 2 , which was higher than 48 mcd/m 2 of Comparative Example 1, 60 mcd/m 2 of Comparative Example 2, and 58 mcd/m 2 of Comparative Example 3.

The afterglow luminance after 8 hours in a state where the light was blocked after light irradiation was 44 mcd/m2 in Example 1, 40 mcd/m2 in Example 2, 41 mcd/m 2 in Example 3, and 42 mcd/m 2 in Example 4. Unlike that, Comparative Example 1 is 19mcd/m2, Comparative Example 2 is 24mcd/m2, and Comparative Example 3 is 21mcd/m2, and in the case of Examples 1 to 4, it can be seen that most of the afterglow luminance has a certain amount at 8 hours.

In the case of Comparative Example 1, the afterglow luminance was measured up to 60 hours, in the case of Comparative Examples 2 and 3, the afterglow luminance was measured up to 120 hours, whereas in the case of Examples 1 to 4, the afterglow luminance was measured up to 180 hours. The luminescent beads can be confirmed to have a semi-permanent lifespan.

That is, in Examples 1 to 4, the highest luminance was 100 mcd / m 2 corresponding to the initial value in a state where light was irradiated to the light-emitting beads and then the light was blocked again, and after 8 hours, the luminance was maintained at least 5 mcd / m 2 or more. . In particular, by having an afterglow luminance of 5 mcd/㎡ or higher even after 180 hours from the time when the light was blocked, it absorbs and accumulates light energy from the light source, converts the accumulated light energy into visible light, and can recognize that it repeatedly emits itself. there is.

Therefore, the luminescent beads of the present invention are easy to attract fish because they have good sensitivity to fish through fluorescent pigments that express orange or green gold colors, and emit light through phosphorescent pigments composed of aluminum oxide, strontium oxide, and boron oxide. Since the processes of absorption, accumulation and light emission can be repeated, the afterglow life can be maintained for more than 8 hours.

In summary, the present invention relates to a luminescent bead for attracting fish, which includes a fluorescent pigment that expresses orange or green gold color on a base resin, a luminescent pigment composed of aluminum oxide, strontium oxide, and boron oxide, biomass, By forming a mixture of vegetable oil, users can visually identify even at night when there is no light, and color-identifiable rockfish, heat, rockfish perch, mullet, rockfish, yellowtail, stone bream, halibut, black sea bream and trout It has a feature that can easily attract fish such as the back.

The luminescent beads of the present invention having such characteristics are not easily decomposed or oxidized by light, oxygen, heat, etc., and have a semi-permanent lifespan by maintaining an afterglow life of 8 hours or more by repeating the process of absorbing, accumulating, and emitting light. It is expected that there will be
