Description
The present invention relates to an eco-friendly biodegradable fishing rod and a method of manufacturing the same, and more particularly, to a method of manufacturing an eco-friendly biodegradable fishing rod and a method of manufacturing the same, Friendly biodegradable fishing rod and a method of producing the same.
Generally, the bolls used for fishing are mainly produced by using lead as a main raw material, and they are manufactured by molding into various shapes and shapes according to their uses. Here, Bongdol is a collective term for weights used for fishing tackles and nets, and in other words, it is also called bolls or footstones. These bongles are often lost to rocks during operation or for other reasons, and sink into the coast or fresh water of the sea.
As such, Bongdol settles in seawater and fresh water is abraded or eroded by attacking various seaweeds, sand, gravel or rocks. In this process, excessive amount of lead, which is harmful heavy metal, dissolves in water and decomposes in water, There has been a case of catastrophic harm to seafood such as fish.
In addition, the lead made of lead is used as a main raw material in the process of producing lead in the atmosphere due to the volatilization of lead by volatile fine lead to heat or air pollution by the worker during the manufacturing process of the lead by the human body, such as lead poisoning There was a harmful effect.
In order to solve these problems, various types of bongles have been studied, and various techniques have been disclosed. In this connection, Korean Patent Laid-Open Publication No. 2004-75846 discloses a fishing tackle in which a metal powder is mixed with a synthetic resin. In domestic patent No. 393470, tungsten, iron, ceramic powder and resin binder are mixed with water, And then heat-treated at 600 ° C to produce a ceramic fishing tackle.
However, the conventional bengles produced by the above method have a number of problems. First, since both of them are manufactured by using synthetic resin as a binder, the fishing weights produced by the fishing weights do not decompose the synthetic resin, which causes new marine pollution. In addition, since ceramic fishing tackles require heat treatment at a high temperature, there is a problem in that the manufacturing cost is increased.
Accordingly, it is easy to manufacture at a relatively low cost and the weight can be changed in various ways. Therefore, not only practical but also environmental friendly bones are required. According to this demand, the present inventor can easily manufacture And the present invention has been completed.
The present invention provides an eco-friendly biodegradable fishing rod and a method of manufacturing the same, which can provide weight balance so that the bait can be placed at a desired position or at a certain depth of water by mixing synthetic resin and metal powder .
In addition, the present invention can replace the fishing rod manufactured from lead or the like as a raw material, and is environmentally friendly biodegradable which can prevent environmental pollution due to oxidation, abrasion, erosion or dissolution even if settled in seawater or freshwater And a method for manufacturing the same.
The various problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.
An eco-friendly biodegradable fishing rod for fishing according to the present invention comprises a metal powder; A synthetic resin to be mixed with the metal powder; And a filler mixed for reinforcing the strength of the synthetic resin, wherein the metal powder is selected from the group consisting of Fe, stainless steel, Ni, cobalt, molybdenum, bismuth, tungsten ), At least one selected from the group consisting of tungsten carbide, tungsten oxide, tin, tin oxide, zinc and manganese, or an alloy in which at least two of them are mixed, wherein the synthetic resin contains biodegradable polyester Wherein the filler is selected from the group consisting of talc, limestone, carbon black, calcium carbonate, titanium dioxide, cyanuric acid, mica, silica, boron nitride, clay, synthetic silicic acid or its salts, organic phosphorus metal salts and kaolin At least one of which is used.
