Description
본 발명은 배터리 분리막 스크랩을 이용한 윤활유용 플라스틱 용기 및 이의 제조방법에 관한 것으로서, 더욱 상세하게는 전기자동차용 배터리 분리막 스크랩을 포함하여 윤활유용 플라스틱 용기의 물성을 향상시킨, 배터리 분리막 스크랩을 이용한 윤활유용 플라스틱 용기 및 이의 제조방법에 관한 것이다.The present invention relates to a plastic container for lubricating oil using battery separator scrap and a method for manufacturing the same, and more particularly, to a plastic container for lubricating oil using battery separator scrap, which improves the physical properties of a plastic container for lubricating oil, including battery separator scrap for electric vehicles It relates to a plastic container and a manufacturing method thereof.
종래의 내연기관 자동차에는 납축전지 또는 납산 배터리(Lead-acid battery)라 불리는 2차전지가 들어가며, 배터리는 몇가지 독성 화학물질과 중금속을 함유하고 있어 다른 쓰레기와 동일한 과정으로 폐기하는 경우, 환경오염을 유발하므로 폐배터리는 지정된 폐기물 처리공장에서 파쇄와 분리과정을 거쳐 재활용되며, 납산 배터리는 현재 기술력으로 광범위한 분야에서 재활용이 가능하다.Conventional internal combustion engine vehicles contain secondary batteries called lead-acid batteries or lead-acid batteries. Batteries contain several toxic chemicals and heavy metals, which cause environmental pollution when disposed of in the same process as other garbage. Therefore, waste batteries are recycled through crushing and separation processes at designated waste treatment plants, and lead-acid batteries can be recycled in a wide range of fields with current technology.
그러나, 최근 판매량이 증가하고 있는 전기 자동차에 핵심 소재인 리튬이온 배터리는, 작고 가벼운 무게와 메모리 현상이 없는 장점으로 2차전지 시장을 주도하고 있음에도 불구하고, 이러한 리튬계 배터리는 배터리 재활용 공정이 에너지 집약적인 공정으로 재활용된 배터리의 금속을 회수하는데 광업 보다 6배에서 10배 더 많은 에너지가 필요하다.However, despite the fact that lithium-ion batteries, which are a key material for electric vehicles whose sales are increasing recently, lead the secondary battery market with their small size, light weight and no memory phenomenon, these lithium-based batteries require a battery recycling process. The intensive process requires six to ten times more energy than mining to recover metals from recycled batteries.
또한, 리튬계 배터리는 크게 양극, 음극, 전해질, 배터리 분리막으로 구성되며, 여기서, 배터리 분리막은 2차전지 내 두 전극(양극/음극)을 격리시켜 물리적 접촉에 의한 전기적 단락을 차단하며, 미세기공 내에 담지된 전해액을 통해 이온이 두 전극 사이로 이동할 수 있는 통로를 제공함으로써 이온 전도성을 가지도록 하는 기능을 가진 필름소재이며, 이러한 배터리 분리막은 미세한 상처로도 상품성이 쉽게 훼손되고, 산업특성상 과잉생산으로 인하여 매달 100㎡의 재고가 발생하고 있으나, 재활용이 어려워 폐기 처리되고 있는 실정이다.In addition, a lithium-based battery is largely composed of an anode, a cathode, an electrolyte, and a battery separator. Here, the battery separator isolates two electrodes (anode/cathode) in a secondary battery to block electrical shorts caused by physical contact, and micropores It is a film material that has the function of having ionic conductivity by providing a passage through which ions can move between two electrodes through the electrolyte contained in the battery. As a result, 100㎡ of inventory is generated every month, but it is difficult to recycle and is being disposed of.
또한, 배터리 분리막은 불순물이 양극/음극 분리 유지 및 리튬 이온 통과 효율에 영향을 줄 수 있어, 잔여 불순물 함량이 낮은, 순도가 높은 분자량이 큰 고밀도 폴리에틸렌(HDPE, High Density Polyethylene) 계통을 주성분으로 사용한다.In addition, the battery separator uses high-density polyethylene (HDPE) as its main component, which has a low residual impurity content and high molecular weight, as impurities can affect the maintenance of anode/cathode separation and lithium ion passage efficiency. do.
한편, 윤활유용 플라스틱 용기는 HDPE(High Density Polyethylene)가 100% 주원료로 마스터 배치를 첨가하여 색상을 내고, 블로우 몰딩(blow molding) 성형기의 압출기에서 170~200℃의 스크류 실린더를 통한 용해과정을 거친 후, 성형기 헤드에서 사출되어 금형(mould)을 이용하여 사출성형하는 공법으로 제조되는 것이 일반적이다.On the other hand, the plastic container for lubricating oil is 100% HDPE (High Density Polyethylene) as the main raw material, adding a master batch to give color, and going through a melting process through a screw cylinder at 170 ~ 200 ℃ in the extruder of a blow molding molding machine. After that, it is generally manufactured by a method of injection molding using a mold by being injected from a molding machine head.
또한, 국내 주요 윤활유 업체인 SK Rubricant, S-Oil, GS칼텍스 등을 비롯하여 외국계 윤활유 업체인 EXXON MOBIL, SHELL, BP CASTROL 등을 포함하는 대부분의 윤활유 업체는, 윤활유를 1 리터, 4 리터, 6 리터 등 플라스틱 소량 용기에 충진시킨 후 포장하여 중국, 동남아 등에 수출하고 있다.In addition, most lubricant companies, including major domestic lubricant companies such as SK Rubricant, S-Oil, and GS Caltex, as well as foreign lubricant companies such as EXXON MOBIL, SHELL, and BP CASTROL, sell lubricants in 1 liter, 4 liter, and 6 liter sizes. It is exported to China, Southeast Asia, etc. after being filled in a small amount of plastic containers such as
이때, 윤활유 제품은 윤활유를 충진시킨 플라스틱 용기를 3~12개씩 종이박스에 포장하여 수출하는 것이 일반적이며, 종이박스에 포장됨에 따라, 외부충격 등에 의해 플라스틱 용기에 균열이 발생하여 윤활유가 누출되어 종이박스가 오염되는 문제점이 있음은 물론, 오염된 박스를 대체할 박스 및 대체할 용기 마련, 불량용기의 회수 및 현지 처리비용 등 경제적 손실이 발생하고 있다.At this time, it is common for lubricating oil products to be exported by packing 3 to 12 plastic containers filled with lubricating oil in a paper box. In addition to the problem of contamination of the box, economic losses such as preparing a box and a container to replace the contaminated box, recovery of defective containers, and local treatment costs occur.
아울러, 최근 ESG(환경ㆍ사회적 가치ㆍ거버넌스 : Environmental, Social and Governance)와 같은 비재무적인 가치의 중요성이 증가하여, 플라스틱 등 인체에 유해하거나 재활용이 어려운 제품에 대한 규제와 사용량에 대한 제재가 강화되는 추세이며, 이에 따라, 윤활유 용기 제조에 사용되는 HDPE(High Density Polyethylene)의 용기당 사용량을 줄임으로써 전반적인 플라스틱 사용량 감소를 통해 ESG 흐름에 부응할 수 있다.In addition, as the importance of non-financial values such as ESG (Environmental, Social and Governance) has recently increased, regulations on products that are harmful to the human body or difficult to recycle, such as plastics, and restrictions on usage are being strengthened. Accordingly, by reducing the amount per container of HDPE (High Density Polyethylene) used in manufacturing lubricant containers, it is possible to respond to the ESG trend through a reduction in overall plastic consumption.
본 발명은 상기의 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은 내마모성, 내화학성, 내후성, 내흡수성 등의 물성이 향상된 윤활유용 플라스틱 용기를 제공하여, 종래의 윤활유용 플라스틱 용기가 금형에 접합되는 과정에서 열화로 인하여 접합부가 충분히 접합되지 않아 접합부가 갈라지거나 미세한 균열이 발생하는 것을 방지하는 것이다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a plastic container for lubricating oil with improved physical properties such as abrasion resistance, chemical resistance, weather resistance, and water absorption resistance, so that the conventional plastic container for lubricating oil can be used in a mold This is to prevent cracking of the joint or occurrence of fine cracks due to insufficient bonding of the joint due to deterioration during the joining process.
