이하에서는, 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, a preferred embodiment according to the present invention will be described in more detail.
본 발명에 따른 항균기능을 갖는 친환경 동분 PVC 필름 제조방법은 항균자속력이 우수한 구리분말(동분)을 함유시켜 항균지속성을 늘리되, 특히 내오염성, 내부착성을 높여 오염원이 쉽게 부착되지 않도록 하여 위생성을 현저히 높인 필름 제조방법을 제공한다.The method of manufacturing an eco-friendly copper powder PVC film having an antibacterial function according to the present invention increases the antibacterial persistence by containing copper powder (copper powder) having excellent antimicrobial magnetic flux, and in particular, increases contamination resistance and adhesion, so that a source of contamination is not easily attached. Provided is a method of manufacturing a film with significantly improved hygiene.
본 발명에 따른 제조방법은 구리를 포함하는 제1펠릿 성형단계; 아연을 포함하는 제2펠릿 성형단계; 제1,2펠릿 및 필름원료 혼합단계; 용융 성형단계;를 포함한다.The manufacturing method according to the present invention includes a first pellet forming step comprising copper; A second pellet forming step comprising zinc; Mixing the first and second pellet and film raw materials; Melt molding step; includes.
이때, 상기 제1펠릿 성형단계는 구리분말과 PVC졸(PVC sol)을 3:7의 중량비로 혼합한 후 압출성형하여 펠릿 형태로 만드는 단계이다.At this time, the first pellet forming step is a step of mixing the copper powder and PVC sol (PVC sol) in a weight ratio of 3:7 and then extruding to form a pellet.
여기에서, 상기 구리분말은 구리 증기응축법(copper vapor condensation)에 의해 제조된 것을 사용하며, 구리 증기응축법이란 고온에서 구리 증기를 만들고 이를 낮은 온도에 분출시켜 구리 증기를 응축시킴으로써 분말화하는 방법을 말한다.Here, the copper powder is produced by copper vapor condensation (copper vapor condensation) method, and copper vapor condensation method is a method of pulverizing copper vapor by making it at high temperature and spraying it at a low temperature to condense copper vapor. Says
이러한 구리분말은 거의 나노크기의 입도를 갖는 분말로서, 전통적으로 알려진 바와 같이 매우 강력한 항균력을 갖는다.Such a copper powder is a powder having a particle size of almost nano-sized, and, as conventionally known, has a very strong antibacterial activity.
특히, 구리는 연성이 있기 때문에 필름으로 제조시 플렉시블한 성질을 유지하는데도 매우 유리하다.In particular, since copper is ductile, it is very advantageous to maintain flexible properties when manufacturing a film.
그리고, 상기 제2펠릿 성형단계는 40nm의 입도를 갖는 산화아연분말과 PVC졸을 4:6의 중량비로 혼합한 후 압출성형하여 펠릿 형태로 만드는 단계이다.In addition, the second pellet forming step is a step in which zinc oxide powder having a particle size of 40 nm and PVC sol are mixed in a weight ratio of 4:6 and then extruded to form pellets.
여기에서, 상기 산화아연분말은 고대로부터 청동합금, 황동합금 등에 사용되어온 천연항균성을 갖는 아연성분을 포함하는 분말로 특히 포도상구균, 폐렴간균 등을 살균하는데 매우 효과적인 것으로 보고되어 있다.Here, the zinc oxide powder has been reported to be very effective in sterilizing staphylococcus aureus, pneumonia, etc. as a powder containing a zinc component having natural antibacterial properties, which has been used for bronze alloys, brass alloys, etc. since ancient times.
이와 같이, 본 발명에서 두 개의 성분을 따로 따로 펠릿화시키는 이유는 균질한 상태로 최대 분산되게 하고, 배합 비율의 정량화를 통해 항균 효과를 극대화시키기 위함이다.As such, the reason for pelletizing the two components separately in the present invention is to maximize the dispersion in a homogeneous state and maximize the antibacterial effect through quantification of the blending ratio.
이것은 추후 카렌다링을 통해 필름 형태로 성형되기 때문에 분산 균일성이 확보되지 않으면 균일한 항균 효과를 나타낼 수 없다. 즉, 그냥 단순히 분말을 정량 배합 후 믹싱하여 카렌다링하게 되면 분말이 국부적으로 쏠리거나 한 쪽에 뭉치는 현상이 발생하는데 이를 해소하기 위함이다.Since it is later formed into a film form through calendaring, it cannot exhibit a uniform antibacterial effect unless dispersion uniformity is secured. In other words, if the powder is simply mixed after quantitative mixing and then calendered, the powder may be localized or aggregated on one side to solve this.
아울러, 상기 제1,2펠릿 및 필름원료 혼합단계는 필름 성형을 위한 원료를 배합하는 단계로서, 제1펠릿과 제2펠릿과 PVC졸 및 옥타메틸사이클로테트라실록산을 2:2:4:2의 중량비로 혼합하는 단계이다.In addition, the first and second pellet and film raw material mixing step is a step of blending the raw materials for film forming, the first pellet and the second pellet and PVC sol and octamethylcyclotetrasiloxane of 2:2:4:2 It is a step of mixing in a weight ratio.
이때, 상기 옥타메틸사이클로테트라실록산(octamethylcyclotetrasiloxane)은 방수성 유기물로서 발수성을 증대시키면서 접촉각을 크게 하여 미끄럼성을 높임으로써 내지문성을 강화시키기 위해 첨가된다.At this time, the octamethylcyclotetrasiloxane (octamethylcyclotetrasiloxane) is a waterproof organic material is added to enhance the anti-fingerprint by increasing the sliding angle by increasing the contact angle while increasing the water repellency.
즉, 지문과 얼룩의 성분은 표면과의 사이에서 활동하는 분자간의 힘으로 부착되는데, 상기 옥타메틸사이클로테트라실록산이 함유되면 얼룩부착력이 약해져서 얼룩성분이 잘 묻지 않아 지문도 남지 않게 되어 필름 표면에 세균을 비롯한 오염물질이 쉽게 부착되지 않음으로써 전염성을 억제, 차단하는데 매우 효과적으로 기여하게 된다.In other words, the components of the fingerprint and the stain are attached by the intermolecular force acting between the surfaces, and when the octamethylcyclotetrasiloxane is contained, the stain adhesion is weakened so that the stain components are not easily adhered and the fingerprint is not left, so that the bacteria on the film surface Contaminants, including, are not easily attached, thereby contributing very effectively to suppressing and blocking infectivity.
그리고, 용융 성형단계는 이렇게 혼합된 원료를 공지의 필름 제조방식으로 성형하여 필름으로 만드는 단계이다.In addition, the melt molding step is a step of molding the mixed raw materials into a film by a known film production method.
여기에서, 본 발명은 상기 제1,2펠릿 및 필름원료 혼합단계에서, 필름 성형을 위한 상기 필름 원료 100중량부에 대해 옴모크롬(ommochrome) 20중량부를 더 첨가할 수 있다.Here, in the present invention, in the first and second pellet and film raw material mixing step, 20 parts by weight of ommochrome may be further added to 100 parts by weight of the film raw material for film forming.
상기 옴모크롬은 아미노산인 트립토판이 붕괴되어 생긴 생물학적 색소그룹으로서 천연방부 기능 및 천연 항바이러스 특성을 제공한다. 이것은 인체에 무해하면서도 효과적인 방어 기작을 유도하며, 필름 표면에서 오랫동안 잔류되는 특성이 있어 항균지속성을 유지하는데 도움을 준다.The ommochrome is a group of biological pigments formed by the breakdown of the amino acid tryptophan, providing natural antiseptic function and natural antiviral properties. This induces an effective defense mechanism that is harmless to the human body, and helps to maintain antibacterial persistence due to its long-standing properties on the film surface.
특히, 상기 옴모크롬은 리스테리아 모노사이토제니스와 살모넬라 엔테리카, 황색포도상구균, 헤모필루스 인플루엔자, 그리고 칸디다 알비칸스 같은 진균 등에 첨가하면 미생물의 성장을 억제하고 사멸시키는데 효과적인 것으로 보고되어 있다.In particular, it has been reported that the OMMO chrome is effective in inhibiting and killing the growth of microorganisms when added to Listeria monocytogenes and Salmonella enterica, Staphylococcus aureus, Haemophilus influenza, and fungi such as Candida albicans.
뿐만 아니라, 본 발명은 상기 제1,2펠릿 및 필름원료 혼합단계에서, 필름 성형을 위한 상기 필름 원료 100중량부에 대해 20nm 입도를 갖는 이산화티탄 분말 30중량부를 더 첨가할 수도 있다.In addition, the present invention may further add 30 parts by weight of titanium dioxide powder having a particle size of 20 nm with respect to 100 parts by weight of the film raw material for film forming in the first and second pellet and film raw material mixing steps.
이때, 이산화티탄은 광화학적 촉매 작용을 통해 항균성을 강화시킬 수 있다.At this time, titanium dioxide can enhance antimicrobial activity through photochemical catalysis.
덧붙여, 본 발명에서는 용융 성형단계 후 제조된 필름이 침지액에 침지된 다음 건조 후 롤 형태로 권취되는 단계가 더 수행될 수 있는데, 연속라인에서 침지액이 담긴 용액팬(PAN)을 일정한 공정속도로 서서히 지나가면서 자동 침지되게 하고, 침지 후 상온 건조구간을 주행한 후 건조로를 거쳐 건조되도록 수행될 수 있다.In addition, in the present invention, the film produced after the melt molding step is immersed in an immersion liquid and then dried and then wound up in a roll form may be further performed, and the solution pan (PAN) containing the immersion liquid in a continuous line is at a constant process speed. It can be carried out to be automatically immersed as it slowly passes through, and then dried through a drying furnace after driving at a normal temperature drying section.
이때, 상온 건조구간을 일정거리 주행시키는 이유는 침지액이 안정화되게 하기 위한 시간을 갖도록 하는 것이며, 이후 30-40℃로 유지되는 건조로를 아주 서서히 통과하면서 건조되도록 구성될 수 있다.At this time, the reason for running the normal temperature drying section for a certain distance is to have time for the immersion solution to stabilize, and then may be configured to dry while passing through the drying furnace maintained at 30-40°C very slowly.
여기에서, 상기 침지액은 루틴 40중량%, 데옥시포도필로톡신 20중량%, 셀레늄 10중량%, 로진 10중량% 및 나머지 수용성 우레탄수지로 이루어진다.Here, the immersion liquid is composed of 40% by weight of rutin, 20% by weight of deoxypodophyllotoxin, 10% by weight of selenium, 10% by weight of rosin and the remaining water-soluble urethane resin.
이 경우, 루틴(Rutin)은 피부 접촉시 염증을 억제하기 위해 첨가되고, 데옥시포도필로톡신(Deoxypodophyllotoxin)은 항알레르기 및 항천식 특성이 있는 것으로 보고된 물질로서, 신체 접촉이 주로 일어나는 부위에 대한 알레르기 발생을 억제하기 위해 첨가된다.In this case, Rutin is added to suppress inflammation upon skin contact, and Deoxypodophyllotoxin is a substance that has been reported to have anti-allergic and anti-asthmatic properties. It is added to suppress the occurrence of allergies.
뿐만 아니라, 셀레늄은 접착계면에서의 표면 산화를 막고, 살균기능도 수행하도록 첨가되며, 로진은 점도 조절 및 침지면 평탄화를 위해 첨가되고, 수용성 우레탄수지는 부착력을 높이기 위한 베이스수지이다.In addition, selenium is added to prevent surface oxidation at the adhesion interface, and to perform sterilization function, and rosin is added for viscosity control and leveling of the immersion surface, and water-soluble urethane resin is a base resin for increasing adhesion.
이와 같은 구성에 따른 항균성을 테스트한 결과, 리스테리아 모노사이토제니스와 살모넬라 엔테리카, 황색포도상구균, 헤모필루스 인플루엔자, 칸디다 알비칸스, 폐렴간균, 곰팡이 등에 대해 항균성이 발현됨을 확인하였다.As a result of testing the antibacterial properties according to this configuration, it was confirmed that the antibacterial properties were expressed against Listeria monocytogenes and Salmonella enterica, Staphylococcus aureus, Haemophilus influenza, Candida albicans, pneumococcal fungi, and fungi.
또한, 내지문성, 내오염성, 이물부착 방지성을 확인하기 위해 필름 표면의 마찰계수를 계측할 결과, 0.06으로서 매우 낮는 저마찰계수를 가짐을 확인하였다.In addition, as a result of measuring the friction coefficient of the film surface in order to check the anti-fingerprint, stain resistance, and anti-adhesive properties, it was confirmed that it has a very low low friction coefficient as 0.06.
이는 표면 미끄럼저항성이 아주 낮아 지문이 묻지 않고, 먼지 등도 부착되지 않을 정도의 수치로서 오염방지특성이 매우 우수한 것이다.This is a level that the surface slip resistance is very low so that fingerprints do not adhere, and no dust, etc., is attached.
이를 통해 병원균의 전염을 예방할 수 있으며, 항균지속성도 유지시키는 것으로 확인되었다.Through this, it was confirmed that the transmission of pathogens can be prevented and the antibacterial persistence is maintained.
