Description

Manufacturing method of eco-friendly fishing gear bongdol and hydrated fishing bongdol manufactured by the method {Manufacturing method of fishing sinker and fishing sinker by the method}

The present invention relates to an environmentally friendly fishing rod, which can replace a fishing rod, which is manufactured by using lead as a raw material, even if precipitated in salty seawater or fresh water, and thus, pollutants in the process due to oxidation, abrasion, erosion or dissolution. The present invention relates to a manufacturing method of an eco-friendly fishing bag hydrated buddle and a hydrated fishing bag prepared by the method, which are environmentally friendly and are not induced, thereby making it possible to variously change the weight of the budding with the reduction of the production cost.

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, the harmful heavy metals lead to excessive elution and spread in the water, adding to the sea pollution and fish. There was a deadly harm to seafood.

In addition, it is harmful to the human body, such as lead poisoning, which is made of lead as a main material, which increases the air pollution due to volatilization of fine lead when heat is left in the air during the manufacturing process, or by contact with worker's skin during the operation There was a disability affected.

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 Publication No. 2004-75846 provides a fishing weight in which metal powder is mixed with a synthetic resin, and Korean Patent No. 393470 mixes tungsten, iron, ceramic powder, and a resin binder with water, followed by press molding. After the heat treatment at 600 ℃ discloses a method for producing a ceramic fishing weight.

However, conventional bumpers produced by the above method have a number of problems. First, as both are manufactured using synthetic resin as a binder, the manufactured fishing rod acts as a cause of new marine pollution because the synthetic resin is not decomposed well. In addition, in the case of the ceramic fishing weight requires a high heat treatment, there is a problem that causes a rise in the manufacturing cost, which is not currently practical.

Accordingly, the manufacturing is easy and the weight can be varied at a relatively low cost, and thus the practicality and environmentally friendly bumper are required. According to such a demand, the present inventors can easily manufacture at an environmentally friendly and low cost. The present invention was completed after studying hydrate-based boulders.

Therefore, the present invention can replace the fishing rods prepared by using lead as a raw material, even if precipitated in salty seawater or fresh water, it is environmentally friendly because it does not cause pollution during oxidation, abrasion, erosion or dissolution. It is an object of the present invention to provide a method for manufacturing an eco-friendly fishing bag bongdol to reduce the cost of production and to vary the weight of the bondol.

In another aspect, the present invention is produced by the above manufacturing method, there is another object to provide an environmentally friendly luggage-based fishing rods.

In order to achieve the above object, the present invention adds and mixes 30 to 300 parts by weight of powdered iron or iron oxide (Fe ₂ O ₃ ) or a mixture thereof and 0.5 to 5 parts by weight of a reducing agent based on 100 parts by weight of a hydrate-based binder, Provided herein is a method for producing an eco-friendly hydrate-based fishing rod, characterized in that the paste is made by adding water, and then molded and dried.

In another aspect, the present invention provides an environmentally-friendly hydrate-based fishing rods, characterized in that produced by the above production method.

Hereinafter, the fishing rods according to the present invention will be described in more detail through the manufacturing method as follows.

The fishing rods according to the present invention are mixed with 30 to 300 parts by weight of powdered iron or iron oxide (Fe ₂ O ₃ ) or a mixture thereof and 0.5 to 5 parts by weight of a reducing agent based on 100 parts by weight of a hydrate-based binder, and It is obtained by adding water to make a paste and then putting it in a mold to form and drying. In other words, the present invention has the greatest feature of using powdered iron or iron oxide or a mixture thereof as an additive for securing sufficient specific gravity while using a hydrate-based binder as a binder for the production of a bodol.

As such, when the hydrate-based binder is used as the binder for producing the boulders, it exhibits excellent environmental friendliness as compared to using a synthetic resin as a conventional binder. In other words, the bongdol prepared using a hydrate-based adhesive does not contaminate the water even if it is used in the water or lost or damaged due to loss in the water, there is an advantage that it is safe as there is no pollution factor even when a person handles.

As the hydrate-based binder, one selected from well-known hydrate-based compounds may be used, and cement which is widely used may be used. Among the cements, it is preferable to use ordinary Portland cement.

Powdered iron or iron oxide or a mixture of iron and iron oxide added to the hydrate-based binder is added to increase the specific gravity of the bongdol, the addition amount is 30 to 300 parts by weight based on 100 parts by weight of the hydrate-based binder . At this time, if the added amount is less than 30 parts by weight, the specific gravity of the manufactured bends is not high enough, so the role of the bends cannot be sufficiently fulfilled, and there is a problem that the use sensitivity, such as the satisfaction on use, falls, and the added amount exceeds 300 parts by weight. Although there is an advantage that the specific gravity of the manufactured boulders is sufficiently high, there is a problem in that the strength is lowered because the amount of the binder is relatively small. Therefore, it is preferable to add iron or iron oxide or a mixture thereof within the above range.

Here, iron or iron oxide can be replaced with non-hazardous stainless steel, nickel (Ni), cobalt (Co), molybdenum (Mo) and tungsten (W), but the iron or iron oxide described above in consideration of manufacturing cost This is preferred. In addition, iron also plays a role in helping photosynthesis of marine organisms, and in view of this, it is highly recommended to use iron or iron oxide or a mixture thereof which is very environmentally friendly.

In this case, iron or iron oxide is preferably used in the form of powder having a particle size of 10㎛ to 100㎛ in consideration of the properties that can be mixed homogeneously with the cement.

The sensitizer added to the hydrate-based binder is generally added in order to secure sufficient strength, and can be added within a conventional addition range. In the present invention, 0.5 to 5 parts by weight is added. At this time, the sensitizer can be selected and used from the well-known, but in consideration of environmental friendliness was used to select methyl cellulose that is easily decomposed without pollution.

In addition to the water reducing agent, a pigment may be further added to enhance the catch by adding color to the manufactured boulders to enhance the appearance of the fish and attracting the fish.

As described above, iron or iron oxide and a water reducing agent in powder form are added to the hydrate-based binder, and then water is added thereto to form a paste. The addition amount of water is not necessarily limited to this, it is good to make a paste using the minimum amount of water possible. Molding may be carried out by pouring the above paste into a mold having a shape of a pedestal to be produced, and if sufficiently dried after molding, the environmentally friendly fishing pedestal according to the present invention may be produced.

The manufactured pedestals have sufficient strength and exhibit high specific gravity, so that they can be substituted for the prepared pedestals based on the existing lead, and also the oxidation, abrasion, There is an advantage of being environmentally friendly because no pollutants are induced in the process by erosion or dissolution. In addition, the use of inexpensive materials has the advantage of reducing the production cost.

Hereinafter, the present invention will be described in more detail with reference to the following examples, which are only presented to aid the understanding of the present invention, but the present invention is not limited thereto.
