Description

납성분이 불포함된 낚시용 무게추 제조 방법{method for producing fishing weights free of lead}Method for producing fishing weights free of lead

본 발명은 낚시용 무게추 제조 방법에 관한 것으로, 더욱더 상세하게는 납성분이 포함되지 않는 낚시용 무게추에 관한 것이다.The present invention relates to a method of manufacturing a weight for fishing, and more particularly, to a weight for fishing that does not contain a lead component.

레저 분야의 하나로 많은 대중이 즐기는 낚시에서도 예전부터 납(Pb)이 비중이 크고, 연성 및 전성이 우수하여 원하는 형상으로의 성형성이 뛰어나며, 가격도 저렴하여 낚시추의 재료로 대부분 활용되어 왔다.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. 이와 같이 낚시추에 사용되는 납은 체내에 많은 양이 축적될 경우 각종 성인병은 물론 신체적,정신적 장애와 신경계 질환 등을 유발하는 것으로 알려져 있다. 이와 같이 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 왔다. 국내의 경우에도 2012년 9월 10일에 발효된 낚시 관리 및 육성법 제 8조에 의거하여 납 성분이 함유된 낚시추의 사용이 금지되게 되었다. 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. 선행 기술로는 실용신안 공개번호 20 2012-0002037 "공기를 이용한 부력조절 낚시 황동추"가 있다. As one of the leisure fields, lead (Pb) has been widely used in fishing enjoyed by many public from the past, and it has excellent formability into a desired shape due to its excellent ductility and malleability, and its price is low, so it has been mostly used as a material for fishing weights. The fact that deformed fish, such as fish with curved backs, are being caught in the coastal waters of Korea in recent years may be due to various pollution, but it is believed that lead-based fishing additives were thrown in the water and seriously polluted the coast, according to environmental organizations. As such, lead used for fishing weight is known to cause various adult diseases, as well as physical and mental disorders, and nervous system diseases, when a large amount of lead is accumulated in the body. As the harmfulness of lead is known in this way, the use of lead-containing fishing weights has been strictly regulated in advanced countries related to overseas leisure such as the United States, Canada, and the United Kingdom, regardless of whether it is harmful due to the dissolution of lead in the water. . In Korea, according to Article 8 of the Fishing Management and Fostering Act, which entered into force on September 10, 2012, the use of fishing weights containing lead was prohibited. There are measures to be deferred for a limited period for importers, domestic manufacturers, and users of fishing weights, but in response to the recent restrictions on the use of lead fishing weights, most of the new products are tungsten-based products considering the specific gravity, or relatively workability. It is a product processed by using excellent brass-based materials. As a prior art, there is Utility Model Publication No. 20 2012-0002037 "Buoyancy control fishing brass weight using air".

납성분이 포함되지 않는 낚시추인 경우 텅스텐이나 황동계 소재를 사용하는 경우가 있으나, 텅스텐의 경우 비중이 납 보다 더 높기 때문에 기능상으로는 우수할 수 있으나, 원재료가 매우 고가이고 제조공정 또한 어려운 단점이 있고, 황동계 소재인 경우 절삭가공하게 되면 재료의 손실과 함께 가공비가 높은 단점이 있다.For fishing weights that do not contain lead, tungsten or brass-based materials may be used.However, since tungsten has a higher specific gravity than lead, it can be excellent in function, but the raw material is very expensive and the manufacturing process is also difficult. In the case of a brass-based material, there is a disadvantage of high processing cost as well as loss of material when cutting is performed.

본 발명은 상기 문제점을 해결하기 위하여 발명된 것으로,The present invention is invented to solve the above problem,

에틸렌프로필렌 고무(ethylene-propylene rubber) 20 중량％, 페라이트 (ferrite) 77 중량%, 징크스테아레이트(ZINC stearate) 1.5 중량％, 사막 엔비스 (SAMAC-NBS) 1.5 중량 중량％를 배합기에 넣어 1차 혼합물을 제조하는 배합 단계; 배합 단계에서 배합된 1차 혼합물에 70℃~75℃가 유지되는 혼합기에서 20분~30분간 믹서하여 2차 혼합물을 제조하는 혼련 단계; 혼련 단계에서 혼련된 2차 혼합물을 규격에 맞게 원하는 크기로 제단하는 제단 단계; 재단 단계에서 제단된 2차 혼합물을 170℃~175℃가 유지되는 프레스 금형틀에 넣어 10분 ~ 15분 동안 압축 성형하는 성형 단계; 성형 단계에서 압축 성형된 제조물을 외관을 검사하여 필요없는 부위는 절단 및 제거하는 사상 검사단계; 사상검사 단계에서 완성된 제조물을 규격에 맞게 소포장 및 출하는 출하 단계;로 이루어진다.First, put 20% by weight of ethylene-propylene rubber, 77% by weight of ferrite, 1.5% by weight of ZINC stearate, and 1.5% by weight of SAMAC-NBS in a blender. A blending step to prepare a mixture; A kneading step of mixing the first mixture blended in the blending step for 20 to 30 minutes in a mixer maintained at 70° C. to 75° C. to prepare a second mixture; A cutting step of cutting the secondary mixture kneaded in the kneading step into a desired size according to the standard; A molding step of compression molding for 10 to 15 minutes by putting the second mixture cut in the cutting step into a press mold maintained at 170°C to 175°C; A finishing inspection step of cutting and removing unnecessary parts by inspecting the appearance of the compression-molded product in the molding step; It consists of a shipment step of packing and shipping the finished product in accordance with the standard in the finishing inspection step.

본 발명은 에틸렌프로필렌 고무, 페라이트, 징크스테아레이, 사막 엔비스와 같은 재료로 성형되기에 납성분이 전혀 없어 친환경적인 낚시용 무게추를 생산할 수 있으며, 생산비용 또한 기존의 텅스텐, 황동계 소재보다 저렴하여 제품 경재력이 있는 효과가 있다. The present invention is made of materials such as ethylene propylene rubber, ferrite, zinc stearray, and desert envis, so it is completely free of lead and can produce eco-friendly weights for fishing, and the production cost is also cheaper than conventional tungsten and brass-based materials. Thus, there is an effect with product economic power.
