Description

Eco-friendly fishing rods and its manufacturing method {Environment friendly plummet for fishing gear and the manufacturing method of the same}

The present invention relates to an environmentally friendly fishing rod and a method for producing the same, and more particularly, at least one powder, ground powder or a mixture of powder and ground powder selected from metals, ceramics, and metal-ceramic composites; Sulfur and modified sulfur produced by using a composition containing dicyclo pentadiene as a starting material; environmentally friendly fishing rods manufactured by mixing, and at least one powder selected from metal, ceramic, and metal-ceramic composites Preparing a mixed composition by mixing a mixture of pulverized product or powder and pulverized product with sulfur and a modified sulfur produced using a composition containing sulfur and dicyclopentadiene as starting materials; Heating the mixed composition to melt reformed sulfur; And cooling and then molding the mixed composition or molding the modified sulfur in a molten state.

According to the present invention, compared to a method of directly processing a metal, ceramic, or metal-ceramic composite by mechanical and thermal methods in manufacturing fishing rods, the manufacturing cost can be reduced and the manufacturing process can be simplified, thereby achieving a process economy. In particular, the powder or pulverized material of the metal, ceramic, or metal-ceramic composite may be mixed with modified sulfur having a density of at least two times higher than that of the general resin, thereby producing a bumper, and thus a smaller amount of metal than that of the general resin. Alternatively, even if the ceramic or a low specific gravity metal or ceramic is used, the effect that can maintain the standard load of the pedestal is expected.

Bongdol, which is used for fishing gear, is mostly manufactured using lead, and is manufactured by molding into various shapes and shapes according to its use. Bongdol is a generic term for weights used for fishing weights, nets, etc., in other words, it is also called botdol or footdol. These boulders are frequently lost to rock during work or for various other reasons and settle down to the ocean shore or fresh water.

Bongdol submerged in the sea or fresh water is worn or eroded by hitting various seaweeds, sand, gravel or rocks.In this process, harmful heavy metals, lead, are eluted in excess and spread in the water. There was a problem that caused fatal harm to seafood.

In addition, Bondos made of lead are left in the air during the manufacturing process, but the amount of lead is volatilized due to heat when it is left to increase air pollution or by contact with the skin of the worker during the Bondo manufacturing work. There was also a problem that has a harmful effect on the human body, such as lead poisoning.

It is announced that lead-based products such as lead-based boulders will no longer be available as of 2012 as a global regulatory target.

In order to improve this problem, researches on various kinds of bondol have been conducted, and as a result, various techniques have been disclosed. In this regard, Korean Patent No. 626804 discloses a fishing weight (bongdol) in which metal powder is mixed with synthetic resin, and Korean Patent No. 393470 mixes tungsten, iron, ceramic powder and resin binder with water and press molding. Then, the method of manufacturing a ceramic fishing weight by heat-processing at 600 degreeC is disclosed.

However, all of the conventional rods manufactured by the aforementioned method used synthetic resin as a binder, and fishing rods manufactured using such synthetic resins have become a new marine pollution source under the influence of hardly degradable synthetic resins. In addition, since the synthetic resin exhibits a low specific gravity of 0.9 to 1.0 g / cm ³ , there is a problem in that it may not be able to maintain a suitable standard load as a fishing rod, depending on the amount of the resin when mixed with a metal or ceramic.

In addition, in the case of ceramic fishing weights, the specific gravity corresponding to lead has attracted attention as a new material that can replace fishing weights using lead, but the ceramic material is manufactured by separately molding the ceramic material into the shape of a stick and firing it at a high temperature. There is a problem that causes the unit price to rise, which is not practical. In addition, in the case of metal, for example, iron, a mechanical processing method should be used to process the shape of the pedestal, and the mechanical processing cost is not small, and there is still a problem in terms of practicality.

On the other hand, Korean Patent No. 798138 has recently provided a method for manufacturing an eco-friendly fishing gear hydrated bump using cement, but there are problems of specific gravity, strength, and corrosiveness, and cement is also known as a harmful composition to the environment, and thus its use is limited.

The present invention has been made to solve the problems described above, the present invention is significantly higher than the resin-based material, by the production of eco-friendly bondol by using a modified sulfur that is easy to process through low temperature heat treatment with a low softening point The objective is to ensure that the peak load satisfies the standard load.

In addition, the present invention is to produce a condensate by thermal agglomeration of the modified sulfur and metal or ceramics, so as to simplify the manufacturing process of the convexity and lower the production cost compared to the production method of the convexity by mechanical and thermal methods such as metal or ceramics For other purposes.

In addition, the present invention is environmentally friendly because it does not cause pollution by oxidation, abrasion, erosion or dissolution, even if precipitated in salty seawater or fresh water, compared to the conventional bongdol made of lead, thus, management of water resources and aquatic resources It is another object of the present invention to manufacture environmentally friendly fishing buds, which are useful for, and in particular, can vary the weight of the boulders.

In order to achieve the object as described above, the present invention comprises at least one powder, ground powder or a mixture of powder and ground powder selected from metals, ceramics, and metal-ceramic composites; It provides an environmentally friendly fishing rod prepared by thermally coagulating; sulfur and a modified sulfur produced using a composition containing dicyclopentadiene as a starting material.

It is preferred that the bondol is prepared to have an average specific gravity of at least 4 g / cm ³ .

The metal includes at least one selected from iron, iron alloy, nickel, cobalt, molybdenum, stainless steel, copper, manganese and tungsten, and the ceramic includes bismuth oxide or a copper-based compound. desirable.

The metal, ceramic or metal-ceramic composite powder, ground powder or a mixture of powder and ground powder is preferably in the range of 0.05mm ~ 10mm based on the average size.

In another aspect, the present invention is a modification prepared by using a composition containing at least one powder, pulverized powder or a mixture of powder and pulverized powder, sulfur, dicyclopentadiene selected from a metal, a ceramic, and a metal-ceramic composite as a starting material Mixing sulfur to prepare a mixed composition; Heating the mixed composition to melt reformed sulfur; And cooling and then molding the mixed composition or molding the modified sulfur in a molten state.

In another aspect, the present invention comprises the steps of melting the modified sulfur produced by using a composition comprising sulfur, dicyclo pentadiene as a starting material; Preparing a mixed composition by mixing the molten modified sulfur with at least one powder, ground powder or a mixture of powder and ground powder selected from metals, ceramics, and metal-ceramic composites; And cooling and then molding the mixed composition or molding the modified sulfur in a molten state.

According to the present invention as described above, by using a modified sulfur having a similar softening point with a general resin and a relatively high density compared to the general resin, it is expected that the effect of producing the fishing rods that substantially satisfy the standard load.

In addition, by manufacturing the condensate for fishing gear by thermal coagulation of the modified sulfur and metal or ceramics, the process economics are simplified and the manufacturing cost is reduced compared to the method for producing the convex stones by the mechanical and thermal method of the metal or ceramic. Achievable effect is expected.

In addition, compared with the conventional barb made of lead, even if precipitated in salty seawater or fresh water, it is eco-friendly because it does not cause pollution by oxidation, abrasion, erosion or dissolution, etc. Therefore, it is useful for the management of water and aquatic resources. In particular, it is expected that the effect of the product can be diversified as the weight of the bondol can be changed in various ways.

The present invention is characterized in that the modified sulfur is thermally coagulated with powders or pulverized products of metals or ceramics or mixtures thereof to form and produce environmentally friendly fishing buds.

More specifically, in the present invention, a powder or a pulverized product such as a metal, a ceramic, a composite of a metal and a ceramic, such as a metal or ceramic, instead of being directly processed into a high-strength, high-hardness material such as a metal or a ceramic, or subjected to a heat treatment, to form a fishing rod. While devising a way to agglomerate without applying heat, the resin-based resin, which has a relatively low melting point as compared to metals, ceramics, metal-ceramic composites, etc., is melted by heating the material at low temperature, and then It is characterized in that the powder or the pulverized product is added, mixed uniformly and molded into the shape of a stick.

However, since the general resin has a very low density as described above, the resin has a low melting point and a relatively high density, so that it can sink more easily in water, and there is almost no problem of environmental pollution even if broken in water, and can be recycled. Another feature is the use of reformed sulfur.

Herein, the metal is a concept including all of a single metal, a metal compound, and a metal mixture having one component thereof, and the ceramic is also a concept including both a ceramic single body, a ceramic compound, and a mixture of ceramics having one component thereof. .

In addition, the powder here means a metal, ceramic, or metal-ceramic composite powder obtained by a method such as synthesis, the pulverized product is obtained by grinding the prepared metal, ceramic or metal-ceramic composite by a mechanical grinding method, etc. do.

Hereinafter, the present invention will be described in detail with reference to the preferred embodiments and drawings.

1 is a manufacturing process diagram of the environmentally friendly fishing rods containing modified sulfur according to an embodiment of the present invention, Figure 2 is a manufacturing process diagram of the environmentally friendly fishing rods according to another embodiment of the present invention.

As shown, environmentally friendly fishing rods according to the present invention can be produced by two processes. That is, one is a method of melting the reformed sulfur by first mixing and heating the reformed sulfur and the metal, ceramic, or metal-ceramic composite powder or pulverized powder, and the other is a metal, A method of mixing ceramics or metal-ceramic composite powders or ground products, the latter being more preferred than on the difficulty of the process.

Hereinafter, the type, size, etc. of the modified sulfur, such as metal, ceramic, and the like, which are components of the bondol according to the embodiment of the present invention, will be divided.

<Types and sizes of metals, ceramics, etc.>

Here, the metal is not particularly limited as a metal that can replace lead, but the density of the reformed sulfur is low, so that the density is a metal having a predetermined value or more so as to have an appropriate weight as a bump when mixed with the reformed sulfur. It is good to be selected. This is the same for both ceramic and metal-ceramic composites.

As a result, in the present invention, the specific gravity of the metal, ceramic, and metal-ceramic composites, which can retain the form of the pedestal while retaining the form of the pedestal, must have a certain value or more, so that the specific gravity of the pedestal produced by combining with modified sulfur It was judged that at least 4g / cm ³ or more can be secured.

As such, the specific gravity of the bondol is 4 g / cm ³ Examples of the target metal that can be ensured above include iron (Fe, specific gravity of 7.9 g / cm ³ ), and its price is low, and it is evaluated as an advantageous material for producing a bondol. Iron alloys alloying other metals with the iron may also be used, and the other metals may include nickel, cobalt, molybdenum, stainless steel, copper, manganese, tungsten, and the like, but are not particularly limited thereto.

However, considering the manufacturing cost and environmental friendliness, double iron or iron alloy is preferred. Such iron or iron alloys also have the advantage of supporting the photosynthesis of marine life.

In the case of ceramics, bismuth oxide (specific gravity 8.9 g / cm ³ ) is typically included, and the same type of compound is included. Such bismuth oxide-based material is appropriately evaluated as a material of a bump in terms of price. do.

Examples of the bismuth oxide-based compound include compounds with cobalt, silicon, iron, vanadium, gallium, zinc, germanium, gallium, chromium, hafnium, aluminum, and the like. The above materials were found to have specific gravity of 8.9 g / cm ³ or more.

In the case of a metal-ceramic composite, for example, a complex of iron and bismuth oxide may be used.

However, it will be apparent that the above metal, ceramic, and metal-ceramic composites are not limited to only the materials listed above.

However, when using multiple metals, ceramics or metal-ceramic composites simultaneously, each metal, ceramic or metal-ceramic composite may satisfy the above specific gravity, but the specific gravity of each constituent metal, ceramic or metal-ceramic composite It is also possible to add the averaged value to represent the specific gravity value as described above.

On the other hand, the metal, ceramic, metal-ceramic composite is used in the form of a powder, a pulverized powder or a mixture of the powder and the pulverized powder, it is preferable that the powder or pulverized powder has a size of 0.05mm ~ 10mm, which is mixed with modified sulfur In this case, the size of the powder or the pulverized product is smaller than the lower limit, and the mixing with the modified sulfur is not easy due to the coagulation between particles, and the size is larger than the upper limit. In larger cases, since it is difficult to form the shape of the pedestal, the powder or the pulverized product of the metal, ceramic, and metal-ceramic composite has its critical meaning in the above size range.

At this time, the metal, ceramic, metal-ceramic composite is preferably used in the form of a mixture of powder and pulverized, in particular, in order to achieve a high packing density is preferably a mixture consisting of granulation and fine grains.

In addition, the powder, or pulverized product of the metal, ceramic, metal-ceramic composite is preferably rounded or spherical, preferably as long as the size is limited as described above, but also in other shapes. .

<Types and Properties of Reformed Sulfur>

The modified sulfur used as a constituent of the bondol according to one embodiment of the present invention is manufactured by using sulfur and a dicyclopentadiene-based modifier as a basic starting composition, and has a melting point of 110 to 130 ° C., It is possible to thermally bond with metal or ceramics, and has specific gravity of 1.7 ~ 1.9g / cm ³ , so it can be used to produce metals and ceramics with low specific gravity resin (0.9 ~ 1.0g / cm ³ ). There is a wide range of choices in specific gravity of the back material.

Such reformed sulfur can be produced in a more improved form. In the present invention, the modified sulfur was further included in the starting composition by further comprising an amino acid compound which is inexpensive and has no decomposition products and thus does not harm odor and health.

When the reformed sulfur is prepared as described above, it becomes a low melting point modified sulfur that can be remelted at a temperature of 100 ° C. or lower so that it can be used with a hydraulic material. After melting the low melting point modified sulfur, the hydraulic material and water are added thereto. When the mixture is reacted chemically, it hardens at room temperature to show the expression of strength, and finally it is manufactured into a very dense and hard cured product.

In addition, a hydrophilic group (radical) should be combined to allow the surfactant to react well with the reformed sulfur so that it can be well dispersed in water and exhibit a homogeneous property.

 The low-melting sulfur modifier used in the present invention is an amino acid compound, which is an organic compound having a basic amino group (-NH) and an acidic carboxyl group (-COOH), which lowers the melting point by reacting with sulfur to weaken the bond. It forms a hydrophilic group, and it is safe because most of them are not decomposed in the manufacturing temperature or use temperature range, and even if some decomposition is done, the price is low.

Amino acid compounds are divided into neutral amino acids, acidic amino acids and basic amino acids according to the number of amino groups and carboxyl groups in the molecule, and are classified into aliphatic amino acids, sulfur-containing amino acids, aromatic amino acids, cyclic amino acids, etc. according to the type of R as a side chain. And amino acid compounds related thereto.

In addition, the major amino acid compounds include glycine, alanine, valine, leucine, threonine, serine, cysteine, methionine, aspartic acid, glutamic acid, glutamine, lysine, lanin, histidine, tyrosine, proline, etc. It forms proteins with polypeptides through and includes amino acid compounds associated with them.

In addition, a low melting point modifier may be used to include one or more ammonium salt compounds in the amino acid compound, the ammonium salt compound is a compound having an ammonia group (NH ₄ ⁺ ), which reacts with sulfur to weaken the bond to reduce the melting point Can be lowered.

Ammonium salts are compounds produced by reaction of an ammonia group with an acid and include organic salts such as ammonium oleate and ammonium stearate as well as general salts such as ammonium acetate, ammonium formate, ammonium sulfate and ammonium phosphate.

If at least one or more of the above amino acid compounds are used in combination with a dicyclopentadiene-based modifier, the melting point is lowered depending on the amount added.

<Production example of modified sulfur>

A two-necked flask was placed in a magnetic stirrer that could be heated, insulated, and stirred, and 60 to 100 g (60 to 80% by weight) of industrial powder sulfur was added to the flask to melt sulfur at about 120 to 130 ° C. 15 to 20 g (12 to 20 wt%) of a dicyclopentadiene solution, in which 10 to 20 wt% of methylcyclopentadiene was added, was slowly added to promote reaction with stirring. At this time, while maintaining the temperature of the reaction between 120 ~ 160 ℃ while maintaining a sharp increase in temperature due to the exothermic reaction was stirred for 30 to 40 minutes.

 When the reaction product is gradually darkened by the reaction, when the reaction is further performed for 10 to 20 minutes, the viscosity increases and the color becomes dark brown. At this time, 10-20 g of low melting point modifiers such as glycine, ammonium formate and glue are used. 8 to 20% by weight) to continue the reaction for about 30 minutes.

When the viscosity is increased by the reaction of sulfur and the modifier, the rotational speed of the magnet bar is remarkably decreased. At this time, the reaction is terminated and cooled to room temperature to prepare a solid low melting point modified sulfur.

Table 1 shows the compositions and remelting temperatures for the low melting point modified sulfur obtained above. In particular, the modifiers in the composition of the low-melting-modified sulfur were mixed with each other or sweet, and the remelting temperature for the low-melting-point reforming sulfur was confirmed by increasing the temperature to 60 ~ 110 ℃ using an oven capable of temperature control.

When only dicyclopentadiene solution was added to sulfur as in Comparative Example 1, the color of the reactant was brown. However, when the amino acid-based compound was included, the reaction product was dark brown in the molten state. In addition, as the content of glycine, a low melting point modifier, was increased to 5 to 15 g (4 to 11.2 wt%), the remelting temperature was decreased. In particular, even when ammonium formate, which is an ammonium salt, is contained in glycine, low melting point reformed sulfur can be produced.

<Production example of ecological fishing sticks>

Hereinafter, an example of manufacturing an environmentally friendly fishing rod according to the present invention using the modified sulfur such as metal, ceramic, etc. will be described.

Iron powder (Gitech Co., Ltd.) and iron pulverized product (wire cut pieces) are prepared respectively or mixed in the ratios shown in Table 1 below, and mixed and mixed compositions using modified sulfur produced according to an embodiment of the present invention. After preparing for 1 hour in an oven set to 110 ℃ mixed well with a spoon and put into a paper mold of 5cm in diameter, chopped by hand, held again in the oven for 30 minutes and then taken out to cool. After leaving for 6 hours or more, the paper was peeled off to prepare a bumper.

In this embodiment, the reformed sulfur and the iron powder and the like are mixed and melted in advance, but the reformed sulfur may be melted first and then mixed with the addition of the iron powder.

The specific gravity of the prepared boulders was measured and the results are shown in Table 1 below. The numerical values corresponding to the following iron powders, iron powders, and modified sulfur indicate weight ratios.

Example Iron Grind (4mm) Iron powder (0.5mm) Iron Powder (70um) Reformed sulfur Packing density Remarks   One   -   -   85   15  4.4   2   -   -   75   25  4.1   3   -   -   60   40  3.8   4   -   90   -   10  4.9   5   -   85   -   15  4.8   6   -   80   -   20  4.4   7   -   33   47   20  4.7   8   -   47.5   40   12.5  4.9   9   -   67.5   20    12.5  5.0   10   -   70   20   10  5.1   11   33   33   24   10  5.4   12   40   30   20   10  5.5   13   60   10   20   10  5.7   14   60   20   10   10  5.8   15   65   25    5   5  5.9

As can be seen from Table 1, it can be seen that the specific gravity increases as the content of iron (specific gravity 7.9) having a large specific gravity increases, and it can be seen that the specific gravity increases as the volume of iron pulverized with a small volume increases. have. In addition, when the iron pulverized powder and iron powders of different sizes are mixed together, the packing density (average specific gravity) is increased, and when the reforming sulfur is too small, there is a problem in that the bonding is insufficient and breakage. It can be seen that the amount of sulfur is in the range of 10 to 25% by weight.

However, the weight percent of the reformed sulfur as described above is calculated in the case of iron, if the use of a high specific weight metal, ceramic, metal-ceramic composite other than iron may vary the weight percent of the modified sulfur.
