공용 현관의 문 손잡이, 엘리베이터의 버튼 등에 구리이온을 함유하는 시판 항균필름을 부착하는 방식이 적용되기도 하나, 평평하거나 원통형의 표면이 아니라면 부착에 어려움이 있거나, 사용하는 과정에서 필름이 찢어지는 등의 손상이 발생하는 문제점이 있다. 또한, 평평한 시트 형태로 시판되는 항균필름의 특성상, 복잡한 구조의 표면에는 적용이 실질적으로 어렵고, 버튼과 같이 움직이는 대상의 표면에 적용하면, 대상의 움직임을 일부 억제하거나, 쉽게 찢어진다는 단점도 있었다.A method of attaching a commercially available antibacterial film containing copper ions to common entrance doorknobs, elevator buttons, etc. is sometimes applied, but if it is not a flat or cylindrical surface, it is difficult to attach or the film is torn during use. There is a problem with damage. In addition, due to the nature of the commercially available antimicrobial film in the form of a flat sheet, it is practically difficult to apply to the surface of a complex structure, and when applied to the surface of a moving object such as a button, it partially suppresses the movement of the object or is easily torn.

The pyrrolidine-based polymer resin contains a pyrrolidine moiety in the molecule to improve the dispersibility of the polyurethane resin, and can help the surface to be quickly dried and cured in the process of forming a film through drying.
구체적으로, 상기 피롤리딘계 고분자 수지로, 폴리비닐피롤리딘이 적용될 수 있다. 상기 폴리비닐피롤리딘을 적용하면, 수용성이어서 분산이 용이하면서, 도포시 초기 건조 과정에 빠른 표면 경화를 유도할 수 있다.Specifically, as the pyrrolidine-based polymer resin, polyvinylpyrrolidine may be applied. When the polyvinylpyrrolidine is applied, it is water-soluble and thus easily dispersed, while rapid surface hardening can be induced during the initial drying process upon application.
상기 피롤리딘계 수지는 상기 폴리우레탄 수지 100 중량부를 기준으로 0.2 내지 2.5 중량부로 포함될 수 있고, 0.5 내지 2 중량부로 포함될 수 있으며, 0.6 내지 1.1 중량부로 포함될 수 있다. 상기 피롤리딘계 수지를 상기 폴리우레탄 수지 100 중량부를 기준으로 0.2 중량부 미만으로 포함하는 경우에는 표면 경화 속도가 늦어질 수 있고, 2.5 중량부 초과로 포함되는 경우에는 액상 항균 조성물의 안정성이 오히려 떨어지거나, 형성되는 항균필름막의 표면이 거칠어질 수 있다.The pyrrolidine-based resin may be included in 0.2 to 2.5 parts by weight, 0.5 to 2 parts by weight, or 0.6 to 1.1 parts by weight based on 100 parts by weight of the polyurethane resin. When the pyrrolidine-based resin is included in less than 0.2 parts by weight based on 100 parts by weight of the polyurethane resin, the surface curing rate may be slowed, and when it is included in more than 2.5 parts by weight, the stability of the liquid antimicrobial composition is rather deteriorated. Alternatively, the surface of the formed antibacterial film may be rough.

The fragrance may be included in the liquid antibacterial composition in an amount of 0.1 to 10 parts by weight based on 100 parts by weight of the polyurethane resin, and may be included in an amount of 0.1 to 7 parts by weight.
상기 액상 항균 조성물은 도포 후 상온 건조에 의해 항균 필름막을 형성하는 것을 특징으로 한다. 상기 도포는, 스폰지 등을 이용하여 진행하는 것이 좋은데, 표면 코팅에 용이하고 액상 조성물이 처리대상 외에 다른 곳에 불필요한 항균필름막을 형성하는 것을 실질적으로 막을 수 있다는 점에서 좋다.The liquid antimicrobial composition is characterized in that an antibacterial film is formed by drying at room temperature after application. The application is preferably carried out using a sponge or the like, which is good in that it is easy to coat the surface and can substantially prevent the liquid composition from forming an unnecessary antibacterial film film elsewhere other than the target to be treated.

상기 표면경화는 사용자가 일반적인 힘으로 접촉했을 때, 조성물이 묻어나지 않는 정도의 경화를 의미하며, 대략 5분 이내, 4분 이내, 구체적으로 2 내지 4분 내에 상기 표면경화가 진행된다.The surface hardening means hardening to the extent that the composition does not come off when the user contacts with a general force, and the surface hardening proceeds within about 5 minutes, within 4 minutes, and specifically within 2 to 4 minutes.
상기 내부경화는, 도막이 내부까지 완전히 경화되어 강한 힘을 가하여도 그 형태가 무너지지 않고, 항균필름막의 형태가 유지되는 상태를 말한다. 이러한 내부경화는 상기 도포 후 대략 3 내지 8시간, 좋게는 4 내지 6시간 내에 완료될 수 있다.The internal curing refers to a state in which the coating film is completely cured to the inside and does not collapse even when strong force is applied, and the shape of the antibacterial film is maintained.

액상 항균 조성물은 경화 전에는 물로 쉽게 제거가 가능하고, 경화가 진행 중인 후에는 95 중량% 이상의 알코올로 제거가 가능하다. 즉, 이러한 방법을 이용해 의도하는 장소에 항균필름막의 형성 및 수정이 가능하다.The liquid antimicrobial composition can be easily removed with water before curing, and can be removed with 95% by weight or more of alcohol after curing is in progress. That is, it is possible to form and modify an antibacterial film film at an intended location using this method.

상기 폴리우레탄 수지, 상기 항균제, 상기 무기입자, 상기 피롤리딘계 수지 등에 대한 설명은 위에서 설명한 것과 동일하므로 그 기재를 생략한다.Descriptions of the polyurethane resin, the antibacterial agent, the inorganic particles, the pyrrolidine-based resin, and the like are the same as those described above, so descriptions thereof are omitted.

구현예의 다른 예인 항균필름막의 제조방법은, 준비단계, 도포단계, 그리고 경화단계를 포함한다.Another example of the embodiment, a method for manufacturing an antibacterial film, includes a preparation step, an application step, and a curing step.
상기 준비단계는 도포대상인 처리대상을 선정하는 단계이다. 항균필름막의 형성이 필요한 부분을 선정하고, 그 표면의 표면 이물질 등을 제거한다.The preparation step is a step of selecting a treatment target, which is an application target. Select the part where the antibacterial film needs to be formed, and remove foreign substances on the surface.

상기 액상 항균 조성물에 대한 구체적인 설명은 위에서 한 설명과 중복되므로 그 기재를 생략한다. A detailed description of the liquid antibacterial composition is omitted because it overlaps with the above description.
상기 도포는 액상 항균 조성물을 그대로 도포하는 경우, 흐름 등이 발생하여 의도하지 않은 곳에 조성물이 도포되는 등의 현상 발생할 수 있다. 이에, 스폰지와 같은 흡수체의 일면을 통해 상기 액상 항균 조성물을 흡수시킨 후에 그 일면을 도포대상(처리대상)의 표면에 도포하는 간접도포 방식을 적용하는 것이 좋다.When the liquid antibacterial composition is applied as it is, a flow or the like may occur, such that the composition is applied to an unintended place. Therefore, it is preferable to apply an indirect application method in which the liquid antibacterial composition is absorbed through one side of an absorbent such as a sponge and then applied to the surface of an application target (treatment target).
상기 간접도포 방식을 적용하는 것은 위에서 언급한 액상 항균 조성물의 의도하지 않는 도포 발생을 미연에 방지하고, 용매의 일부를 빠르게 제거하며, 이를 통해 보다 빠른 경화를 유도할 수 있다는 점에서 좋다. Applying the indirect application method is good in that it prevents unintentional application of the above-mentioned liquid antimicrobial composition in advance, quickly removes a part of the solvent, and induces faster curing through this.
이렇게 흡수체를 통한 간접도포 방식을 진행하는 경우, 도포대상의 표면이 평평하지 않은 경우에도 안정적으로 액상 항균 조성물의 도포가 가능하고, 보다 빠른 경화 유도가 가능하다. In the case of proceeding with the indirect application method through the absorber, even when the surface of the application target is not flat, it is possible to stably apply the liquid antibacterial composition and more rapidly induce curing.
이렇게 도포한 후에는 표면만의 경화가 진행된 항균 필름 전구체막을 얻을 수 있다. 상기 표면의 경화라 함은, 손으로 가할 수 있는 강한 압력을 가하면 그 형태가 변형되나 압력을 가하지 않는 접촉으로 액상 항균 조성물이 묻어나오지 않고 끈적임이 없는 정도의 경화를 의미한다. 이러한 경화까지는 통상 5분 이내, 좋게는 4분 이내의 시간이 소요되며 2 내지 4분에 표면경화가 완료되는 것이 좋다.After coating in this way, an antibacterial film precursor film in which only the surface is cured can be obtained. Curing of the surface means that when a strong pressure that can be applied by hand is applied, the shape is deformed, but curing to the extent that the liquid antimicrobial composition does not come out and is not sticky by contact without applying pressure. It usually takes less than 5 minutes, preferably less than 4 minutes, and it is preferable that the surface hardening is completed in 2 to 4 minutes.
상기 항균 필름 전구체막은, 상기 액상 항균 조성물에서 용매를 제거한 것과 유사한 구성을 갖는다. 다만, 용매인 물과 에틸피롤리디논이 일부 제거되어 그 함량이 줄어들어, 상대적으로 필름전구체, 피롤리딘계 고분자 수지, 금속염 그리고 무기입자의 함량이 늘어난다.The antimicrobial film precursor film has a configuration similar to that obtained by removing the solvent from the liquid antimicrobial composition. However, water and ethylpyrrolidinone, which are solvents, are partially removed and their contents are reduced, and the contents of the film precursor, pyrrolidine-based polymer resin, metal salt, and inorganic particles are relatively increased.
상기 경화단계는 상기 항균필름 전구체막을 실온 건조하여 항균필름막을 형성하는 단계이다. 상기 항균필름막에 대한 구체적인 설명은 위에서 한 설명과 중복되므로 그 기재를 생략한다. The curing step is a step of drying the antimicrobial film precursor film at room temperature to form an antimicrobial film film. Since the detailed description of the antibacterial film overlaps with the above description, the description thereof will be omitted.
상기 항균필름막은 항균제가 상기 항균필름막 내에 고르게 분포하여 지속적인 항균 특성을 나타낼 수 있다. The antibacterial film may exhibit continuous antibacterial properties by uniformly distributing the antimicrobial agent within the antimicrobial film.
은이온을 500 ppm과 1000 ppm으로 적용한 상기 액상 항균 조성물을 적용한 항균시험성적서에 의하면, 실온에서 10 내지 60분 동안의 접촉 시간에 유의미한 균 감소율을 보이며, 이는 액상 항균 조성물과 이로부터 형성되는 항균필름막 모두 우수한 항균 특성이 유지된다(TRYPTIC SOY AGAR 배지, Staphylococcus aureus ATTCC 6538 균 적용 실험).According to the antibacterial test report applying the liquid antibacterial composition to which silver ions were applied at 500 ppm and 1000 ppm, a significant bacterial reduction rate was shown at a contact time of 10 to 60 minutes at room temperature, which is a liquid antibacterial composition and an antibacterial film film formed therefrom All of them maintain excellent antibacterial properties (TRYPTIC SOY AGAR medium, Staphylococcus aureus ATTCC 6538 application test).
이하, 구체적인 실시예를 통해 보다 구체적으로 설명한다. 하기 실시예는 본 발명의 이해를 돕기 위한 예시에 불과하며, 본 발명의 범위가 이에 한정되는 것은 아니다.Hereinafter, it will be described in more detail through specific examples.

항균물필름 물성평가Evaluation of antibacterial film properties
(1)액상 항균 조성물의 항균 작용 평가(1) Evaluation of antibacterial action of liquid antibacterial composition
액상 항균 조성물의 살균력 테스트(ASTM E2315 - 16, TIME KILL TEST)를 진행했다.A bactericidal power test (ASTM E2315 - 16, TIME KILL TEST) of the liquid antibacterial composition was conducted.
액상 항균 조성물의 살균력테스트는 D/E NEUTRALIZING BROTH 중화방법, 25 ℃, 은이온 농도가 500/1000ppm인 액상 항균 조성물 원액을 TRYPTIC SOY AGAR 배지에 배양되는 Staphylococcus aureus ATTCC 6538 균에 접촉시키고 시간의 경과에 따른 균수를 확인하여 진행했다. 각각 접촉 전, 접촉 10분후, 30분후, 60분후의 균수를 각각 측정했고, 상용대수감소치 및 균감소율을 평가하여 액상 항균 조성물(또는 이를 이용해 형성된 항균필름막)의 살균력을 항균 작용을 평가하였다. The bactericidal power test of the liquid antibacterial composition was performed by contacting Staphylococcus aureus ATTCC 6538 bacteria cultured in the TRYPTIC SOY AGAR medium with the stock solution of the liquid antimicrobial composition having a silver ion concentration of 500/1000ppm at 25 ℃ by the D/E NEUTRALIZING BROTH neutralization method, and over time It was carried out by checking the number of bacteria. The number of bacteria was measured before contact, 10 minutes after contact, 30 minutes after, and 60 minutes after contact, respectively, and the antibacterial activity of the liquid antibacterial composition (or the antibacterial film formed using the same) was evaluated by evaluating the normal log reduction value and the bacteria reduction rate.
상기 표 1의 결과를 참조하면, 500ppm의 은이온이 함유된 액상 항균 조성물 및 1000ppm의 은이온이 함유된 액상 항균 조성물의 살균 효과를 평가했을 때, 실시예 1-2에 비해 실시예 1-1에서, 은이온의 함유량이 더 적을 때, 시간 경과에 따른 살균 효과가 보다 우수한 점을 확인했다. 이는 농도 의존적인 항균 특성을 보여주는 결과로, 액상 항균 조성물(또는 이를 적용하여 형성된 항균 필름막) 내에서도 은이온의 항균력이 잘 발휘된다는 것을 확인할 수 있었다.Referring to the results of Table 1, when the sterilization effect of the liquid antimicrobial composition containing 500 ppm of silver ions and the liquid antimicrobial composition containing 1000 ppm of silver ions was evaluated, Example 1-1 compared to Example 1-2 In, it was confirmed that when the content of silver ions is smaller, the sterilization effect over time is more excellent. As a result of showing concentration-dependent antibacterial properties, it was confirmed that the antibacterial power of silver ions is well exhibited even in the liquid antimicrobial composition (or the antibacterial film formed by applying the same).
