Description
본 발명은 낚시용 무게추 제조방법에 관한 것으로, 상세하게는 납이 포함되지 않은 소재를 사용하여 낚시용 무게추를 제조할 수 있는 친환경 낚시용 무게추 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a fishing weight, and more specifically, to a method of manufacturing an eco-friendly fishing weight that can manufacture a fishing weight using a material that does not contain lead.
레저 분야의 하나로 많은 대중이 즐기는 낚시에서 예전부터 낚시추는 대부분 납(Pb)으로 이루어진 것을 많이 사용했다.In fishing, which is enjoyed by many people as a leisure activity, fishing lures made of lead (Pb) have long been used.
이것은 납은 상대적으로 비중이 크고, 연성 및 전성이 우수하여 원하는 형상으로의 성형성이 뛰어나며, 가격도 저렴하여 낚시추의 재료로 대부분 활용되어 왔다.Lead has a relatively large specific gravity and is excellent in ductility and malleability, so it has excellent moldability into desired shapes and is inexpensive, so it has been mostly used as a material for fishing weights.
그런데 최근 우리나라 연근해 해역에서 등이 휜 물고기 등 기형어가 심심찮게 잡히고 있는 것은 각종 공해 탓도 있겠지만 이러한 납 소재의 낚시추가 수중에 버려져 연안을 심각하게 오염시킨 것도 한 요인이 됐을 것으로 환경단체는 보고 있다.However, environmental groups believe that the recent frequent occurrence of deformed fish, such as fish with curved backs, in the coastal waters of Korea may be due to various types of pollution, but the fact that these lead-based fishing weights were discarded in the water, seriously polluting the coast, may also have been a factor.
이와 같이 낚시추에 사용되는 납은 체내에 많은 양이 축적될 경우 각종 성인병은 물론 신체적,정신적 장애와 신경계 질환 등을 유발하는 것으로 알려져 있다.As such, lead used in fishing lures is known to cause various adult diseases as well as physical and mental disorders and nervous system diseases when accumulated in large amounts in the body.
이러한 납의 유해성이 알려짐에 따라, 실제 수중에서 납의 용해에 따른 유해성 여부를 떠나서 미국, 캐나다, 영국 등 해외 레저관련 선진 국가들에서도 환경보호를 위해 납이 함유된 낚시추의 사용이 엄격히 규제되어 왔고, 국내의 경우에도 2012년 9월 10일에 발효된 낚시 관리 및 육성법 제 8조에 의거하여 납 성분이 함유된 낚시추의 사용이 금지되게 되었다. As the harmfulness of lead became known, the use of lead-containing fishing weights has been strictly regulated to protect the environment in advanced leisure countries such as the United States, Canada, and the United Kingdom, regardless of whether lead is actually harmful due to dissolution in the water. In Korea, the use of fishing weights containing lead was banned pursuant to Article 8 of the Fishing Management and Promotion Act, which came into effect on September 10, 2012.
낚시추의 수입업자, 국내 제조업자 및 사용자를 위해 한정된 기간 동안 유예하는 조치가 있지만, 최근 이러한 납 낚시추의 사용규제에 대응하여 신규한 제품 대부분은 비중을 고려한 텅스텐계의 제품이거나, 가공성이 비교적 우수한 황동계의 소재를 사용하여 절삭가공한 제품이다. Although there are measures to delay the use of lead fishing lures for a limited period of time for importers, domestic manufacturers, and users of fishing lures, most of the new products in response to the recent regulations on the use of lead fishing lures are tungsten-based products that take specific gravity into account, or are relatively easy to process. This product is machined using excellent brass-based materials.
그런데 텅스텐이나 황동계의 소재는 상대적으로 비싼 단점이 있어서, 선행기술 대한민국 공개특허 10-2020-0022864(2020.3.4.)에 따르면, 기존 납소재로 만든 추의 외면에 고무를 코팅한 납은폐층이 형성된 구조의 낚시추가 제안되었다. However, tungsten or brass-based materials have the disadvantage of being relatively expensive, so according to the prior art Korean Patent Publication No. 10-2020-0022864 (March 4, 2020), a lead hiding layer coated with rubber on the outer surface of a weight made of existing lead material A fishing weight of this formed structure was proposed.
그러나 이러한 고무코팅층이 있어도 오래 사용하거나 물속에 장시간 침전되면 결국 고무코팅층이 벗겨져 납이 노출되기 때문에 큰 효과를 기대하기 어렵다.However, even if such a rubber coating layer is used for a long time or is submerged in water for a long time, the rubber coating layer will eventually peel off and the lead will be exposed, so it is difficult to expect a significant effect.

이하에서 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예를 상세하게 설명하기로 한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.
도 1은 본 발명의 일 실시 예를 따른 친환경 낚시용 무게추 제조방법을 나타내는 순서도이다.Figure 1 is a flowchart showing a method of manufacturing an eco-friendly fishing weight according to an embodiment of the present invention.
본 발명에 따라 낚시용 무게추를 제조하는 방법은 크게, 배합단계, 혼련단계, 재단단계, 성형단계, 사상 검사단계, 출하단계로 진행된다.The method of manufacturing a fishing weight according to the present invention largely progresses into a mixing step, a kneading step, a cutting step, a forming step, a finishing inspection step, and a shipping step.
먼저, 상기 배합단계에 대해 설명한다.First, the mixing step will be described.
상기 배합단계는 소재를 모두 배합하여 1차혼합물을 제조하는 공정이다.The mixing step is a process of mixing all materials to produce a primary mixture.
1차 혼합물은 에틸렌프로필렌 고무(ethylene-propylene rubber) 20 중량％, 페라이트 분말 (ferrite) 77 중량%, 징크스테아레이트(ZINC stearate) 15 중량％, Sulfenamide 계의 고무가황촉진제 NBS(NOBS) 15 중량％를 배합기에 넣어 배합하여 제조한다.The first mixture is 20% by weight of ethylene-propylene rubber, 77% by weight of ferrite powder, 15% by weight of zinc stearate, and 15% by weight of NBS (NOBS), a sulfenamide-based rubber vulcanization accelerator. It is manufactured by mixing in a blender.
여기서, 상기 에틸렌프로필렌 고무(EPDM)는 100 중량부에 대하여 카본블랙 50 중량부와, 산화제 5 중량부와, 노화방지제 5 중량부와, 촉진제 4.6 중량부와, 점착제 3 중량부와, 이형제 1.5 중량부를 배합하여 만들어진다.Here, the ethylene propylene rubber (EPDM) contains 50 parts by weight of carbon black, 5 parts by weight of an oxidizing agent, 5 parts by weight of an anti-aging agent, 4.6 parts by weight of an accelerator, 3 parts by weight of an adhesive, and 1.5 parts by weight of a mold release agent, based on 100 parts by weight of the ethylene propylene rubber (EPDM). It is made by combining parts.
우선, 카본블랙은 고무합성시 사용되는 보강제로서, 탄소를 포함하는 물질을 불완전연소시켜 제조할 수 있으며 그을음과 같은 검은 탄소미립자를 말한다.First of all, carbon black is a reinforcing agent used in rubber synthesis. It can be manufactured by incomplete combustion of materials containing carbon and refers to black carbon particles resembling soot.
카본블랙을 혼합하면 고무의 경도가 증가하고 강도, 내구성, 내마모성이 크게 향상된다. 입자가 작은 카본블랙을 사용하면 강도와 내마모성이 커지고, 큰 입자를 사용하면 유연성이 있는 고무가 만들어진다.Mixing carbon black increases the hardness of rubber and significantly improves strength, durability, and wear resistance. Using carbon black with small particles increases strength and wear resistance, and using large particles creates flexible rubber.
카본블랙은 SAF, ISAF, HAF, MAF, FEF, SRF, GPF, APF, FF, CF, SCF 및 ECF와 같은 퍼니스 블랙(퍼니스 카본 블랙); 아세틸렌 블랙(아세틸렌 카본 블랙); FT 및 MT와 같은 서멀 블랙(서멀 카본 블랙); EPC, MPC 및 CC와 같은 채널 블랙(채널 카본 블랙); 그래파이트일 수 있으나 바람직하게는 HAF(High Abrasion Furnace) 카본블랙과 FEF(Fast Extrusion Furnace)일 수 있다.Carbon black includes furnace blacks such as SAF, ISAF, HAF, MAF, FEF, SRF, GPF, APF, FF, CF, SCF and ECF; Acetylene black (acetylene carbon black); thermal blacks such as FT and MT (thermal carbon black); Channel Black (Channel Carbon Black) such as EPC, MPC and CC; It may be graphite, but preferably HAF (High Abrasion Furnace) carbon black and FEF (Fast Extrusion Furnace) may be used.

It is used for high hardness products and is good for increasing tensile strength.
FEF(Fast Extrusion Furnace)는 내부의 발열이 적고, 열전도성이 좋고 압출용에 적합하다. 즉, 성형성이 향상되고 경도를 조절한다. FEF (Fast Extrusion Furnace) generates little internal heat, has good thermal conductivity, and is suitable for extrusion. In other words, formability is improved and hardness is controlled.
다음으로 산화아연은 에틸렌프로필렌 100 중량부에 대해 5 중량부가 배합된다. Next, 5 parts by weight of zinc oxide is mixed with 100 parts by weight of ethylene propylene.
