The present invention relates to a hypochlorous acid sterilizing water composition, and more particularly, by mixing a certain amount of sodium hypochlorite in a mixture of citric acid and vinegar to prepare hypochlorous acid sterilizing water, the generation of chlorine gas from hypochlorous acid sterilizing water Hypochlorite sterilized water composition that can be produced at high concentration and stable at pH value, as well as space spraying during operation, is easy to comprehensive hygiene management and can be manufactured at low manufacturing cost.

일반적으로, 강한 살균력을 필요로 하는 살균수는 살균과 동시에 인체나 환경에도 악영향을 끼치는 등 다양한 문제점이 발생하고 있다. In general, sterilizing water that requires strong sterilizing power has various problems such as adversely affecting the human body and the environment at the same time as sterilization.
이에, 살균수가 가지는 많은 문제점들을 해결하기 위하여 차아염소산계의 전해수 염산 혼합물 등이 개발되었고, 특히 차아염소산(hypochlorous acid)은 염소계 살균소독제로서 강력한 산화제로서, pH에 의해 그 존재 형태가 달라지기 때문에, 강산성차아염소산수(pH 2.7이하, 유효염소농도 20~60ppm)와, 미산성차아염소산수(pH 5.0~6.5, 유효염소농도 10~30ppm)로 분류하여 용도에 따라 사용이 이루어지고 있다. Thus, in order to solve many problems of sterilizing water, hypochlorous acid-based electrolytic water hydrochloric acid mixtures and the like have been developed. Especially, hypochlorous acid is a chlorine-based disinfectant, which is a powerful oxidizing agent, and its present form varies depending on pH. Strong acid hypochlorous acid (pH 2.7 or less, effective chlorine concentration 20 ~ 60ppm) and unacidic hypochlorous acid (pH 5.0 ~ 6.5, effective chlorine concentration 10 ~ 30ppm) is classified according to the purpose of use.
그런데 차아염소산수는 동일 유효 염소 농도의 차아염소산나트륨보다 살균력 및 표백력 등이 우수하나 지금까지 알려진 제조 설비를 이용한 차아염소산수의 제조 방법은 높은 비용을 요구하고 나아가 그러한 방법으로는 고농도의 차아염소산수 제조가 경제적 및 현실적으로 불가능하여 널리 사용될 수 없었다.Hypochlorite water has better sterilizing power and bleaching power than sodium hypochlorite at the same effective chlorine concentration.However, the method for producing hypochlorous water using the known manufacturing equipment requires a high cost, and further, such a method can be used with high concentration of hypochlorous acid. Water manufacture was economically and practically impossible and could not be widely used.
또한, 차아염소산수를 생성하기 위해서는 전기 분해 방법, 염산 혼합 방법, 탄산가스 혼합 방법 등이 주로 이용되고 있다. In addition, in order to generate hypochlorous water, an electrolysis method, a hydrochloric acid mixing method, a carbon dioxide gas mixing method, and the like are mainly used.
하지만, 전기 분해 방법의 경우에는 미반응의 전해질이 잔존하고 있어 살균, 소독을 위해 사용하였을 때 피소독물에서 잔류하여 피소독물의 변형을 유발하거나 얼룩을 발생시키는 등의 문제점이 있다.However, in the case of the electrolysis method, an unreacted electrolyte remains, and when used for sterilization and disinfection, there is a problem such as to remain in the toxin to cause deformation or staining of the toxin.
또한, 염산 혼합 방법의 경우에는 대량의 염소 가스가 발생하고, 염산의 첨가량에 따라 pH가 크게 변화하게 되어 정량으로 제조가 어려운 문제점이 있다. In addition, in the case of the hydrochloric acid mixing method, a large amount of chlorine gas is generated, the pH is greatly changed according to the amount of hydrochloric acid is added, there is a problem that it is difficult to quantitate.
또한, 탄산 가스 혼합 방법은 차아염소산수의 생성 후 탄산가스가 개방되면서 pH 값이 상승하기 때문에 차아염소산수의 보관이 매우 어려렵고, 특히 물과 혼합이 이루어질 때 탄산가스가 바로 물로 변화하기 때문에 살균 효과가 떨어지게 되며, 유기물에 접촉시 살균력이 현저하게 떨어지게 되는 문제점이 있다.In addition, the carbon dioxide gas mixing method is very difficult to store the hypochlorous acid water because the pH value rises as the carbon dioxide gas is opened after the generation of hypochlorous acid water, especially since the carbon dioxide gas is immediately converted to water when sterilized by sterilization. The effect is reduced, there is a problem that the sterilization power is significantly reduced when contacting the organic material.

Pure is known as glacial acetic acid because it has a high freezing point and easily becomes a solid in winter.
본 발명에서는 차아염소산 살균수를 제조하기 위한 주원료로 구연산(Citric acid)을 이용하며, 상기 구연산 70.0중량% ~ 97.0중량%와, 아세트산(acetic acid) 3.0중량% ~ 30.0 중량%를 혼합한 혼합물을 제조한다.In the present invention, citric acid is used as a main raw material for preparing hypochlorous acid sterilized water, and a mixture of 70.0 wt% to 97.0 wt% of citric acid and 3.0 wt% to 30.0 wt% of acetic acid is prepared. Manufacture.
이때, 상기 구연산이 70.0중량% 보다 미만으로 혼합되는 경우에는 충분한 살균력을 제공하지 못할 우려가 있고, 97.0중량%를 초과하여 혼합되는 경우에는 구연산이 가지는 특유의 냄새가 살균수로부터 발생하게 되어 사용상 불편함을 제공할 우려가 있으며, 이와 동시에 아세트산의 함유량이 일정량 함유되지 못하게 되어 살균 효과가 저하되어 높은 살균력을 제공하지 못할 수 있다.At this time, when the citric acid is mixed less than 70.0% by weight may not provide sufficient sterilization power, when the mixture is more than 97.0% by weight, the characteristic smell of citric acid is generated from the sterilized water, inconvenience in use At the same time, there is a fear that the content of acetic acid is not contained in a certain amount, so that the sterilization effect is lowered, it may not provide a high sterilization power.
이에, 본 발명에서는 구연산 및 아세트산의 혼합시 상기 구연산은 총 중량에 있어서 70.0중량% ~ 97.0중량%의 범위 내에서 혼합됨이 바람직하다.Thus, in the present invention, when the citric acid and acetic acid are mixed, the citric acid is preferably mixed within the range of 70.0% by weight to 97.0% by weight.
또한, 본 발명에서는 차아염소산 살균수를 제조하기 위해 구연산과 혼합되는 아세트산(acetic acid)이 3.0중량% ~ 30.0 중량%의 범위 내에서 혼합이 이루어짐이 바람직하다. In addition, in the present invention, the acetic acid (acetic acid) mixed with citric acid to prepare hypochlorous acid sterilized water is preferably mixed within the range of 3.0% by weight to 30.0% by weight.
이는, 상기 아세트산이 산성으로 이루어져 있고, 강력한 방부제임과 동시에 살균제의 역할을 수행하므로, 그 혼합량이 3.0 중량% 미만일 경우에는 각종 세균에 대한 살균력이 충분하게 제공되지 못할 뿐만 아니라, 방부제의 역할을 충분히 하지 못하는 문제가 발생할 수 있고, 30.0 중량%를 초과하여 할 경우에는 아세트산이 가지는 고유의 향이 너무 진하여 제조된 소독제의 향에도 영향을 미칠 수 있는 문제가 있다.Since the acetic acid is acidic and is a strong preservative and at the same time plays a role of a disinfectant, when the mixed amount is less than 3.0% by weight, not only the sterilizing power for various bacteria is provided but also a sufficient role of the preservative. If you do not have a problem, and if it exceeds 30.0% by weight, there is a problem that the inherent aroma of acetic acid is too thick can affect the aroma of the prepared disinfectant.
이때, 본 발명에서는 상기 아세트산의 경우, 양조식초, 현미식초, 양파식초 뿐만 아니라, 과일식초 중 어느 하나, 또는 그 이상을 선택하여 구연산과 혼합하여게 사용될 수 있다.At this time, in the present invention, in the case of acetic acid, not only brewing vinegar, brown rice vinegar, onion vinegar, but also any one or more of fruit vinegar can be used to be mixed with citric acid.
한편, 본 발명은 상기 구연산 및 아세트산이 중량비로 혼합된 혼합물에 차아염소산 나트륨(NaClO)을 일정 중량비로 더 혼합하여 차아염소산수를 제조하게 된다. On the other hand, the present invention is further prepared by mixing sodium hypochlorite (NaClO) in a certain weight ratio to the mixture of citric acid and acetic acid in a weight ratio to produce hypochlorous acid water.
여기서, 차아염소산 나트륨(NaClO)은 물 속에서 반응에 의해 산소가 발생하고 산소를 이용하여 폐수 내에 존재하는 시안을 시안산으로 만든다. 그 후 시안산을 다시 질소와 탄산가스로 분해하여 무해화 한다. 낮은 pH를 갖을수록 살균력이 강하고, 단백질, 당분, 아미노산 등에 의해 살균력이 감소된다. 살균력은 100ppm 농도로 희석 후 pH8-9로 조절한 것이 가장 높다. 차아염소산 나트륨은 엷은 녹황색 또는 무색의 액체이고, 염소냄새가 나며, 수용액을 오래 저장하면 분해되어 염소가스로 변환되면서 살균제로서의 효력이 사라진다.Here, sodium hypochlorite (NaClO) generates oxygen by reaction in water and uses cyanogen to make cyanic acid present in the wastewater. After that, the cyanic acid is decomposed again into nitrogen and carbon dioxide to be harmless. The lower the pH, the stronger the bactericidal power, and the lower the bactericidal power by protein, sugar, amino acid and the like. The sterilizing power is best adjusted to pH8-9 after dilution to 100ppm concentration. Sodium hypochlorite is a pale greenish yellow or colorless liquid, smells of chlorine, and when stored for a long time, it is decomposed and converted into chlorine gas, which loses its effect as a disinfectant.
이와 같은 차아염소산 나트륨은 식품의 부패균 또는 병원균을 제거를 위한 살균제로서 사용되며 살균 소독제, 표백제, 산화제로서 사용한다. 이 물질은 분해되면서 산소를 방출한다. 물에 용해가 잘 되며, 저장 중 수용액이 분해되어 염소가스가 생기기 때문에 장기간 보관 시 살균제로서 효력이 떨어진다.Such sodium hypochlorite is used as a disinfectant for removing rot or pathogens of food and is used as a disinfectant disinfectant, bleach and oxidant. This substance breaks down and releases oxygen. It dissolves well in water and decomposes as a disinfectant when stored for a long time because aqueous solution decomposes during storage to generate chlorine gas.
