Description

기화성 방청 흡습제 제조방법{Manufacturing method of Desiccant which has volatile corrosion inhibiting effect}Manufacturing method of desiccant which has volatile corrosion inhibiting effect}

본 발명은 기화성 방청 흡습제 제조방법에 관한 것으로, 특히 식품첨가물이나 식품추출물들로 이루어진 산소 흡습제, 응결제, 산화방지제 및 기화성 방청제를 사용하여 인체에 접촉되더라도 안전하고, 환경오염을 유발하지 않고, 흡습제를 응결시키는 응결제를 혼합하여 기화성 방청 흡습제의 수분 흡습률과 점도가 최적이 되도록 하여 수분 흡습시 기화성 방청 흡습제를 젤상태로 유지되도록 하여 기화성 방청 흡습제가 포장된 부직포 외부로 기화성 방청 흡습제가 유출되는 것을 방지하고, 산소 흡습제를 첨가하여 금속류의 포장 및 보관시 산소 흡습제에 의해 산소를 흡수하여 고온 및 다습한 악조건에서도 방청기능이 탁월한 기화성 방청 흡습제 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a vaporizable rust preventive desiccant, and in particular, using an oxygen absorbent composed of food additives or food extracts, a coagulant, an antioxidant, and a vaporizable rust inhibitor, it is safe even if it comes into contact with the human body, does not cause environmental pollution, and uses a desiccant. By mixing a condensing agent to make the moisture absorption rate and viscosity of the vaporizable rust preventive desiccant optimal, it keeps the vaporizable rust preventive desiccant in a gel state when moisture is absorbed to prevent the evaporative rust preventive desiccant from leaking out of the nonwoven fabric packed with the vaporizable rust preventive desiccant. And, the present invention relates to a method for producing a vaporizable rust-preventing desiccant having excellent rust-prevention function even under adverse conditions of high temperature and high humidity by absorbing oxygen by an oxygen desiccant when packing and storing metals by adding an oxygen desiccant.

금속산업이 발달함에 따라 철 또는 비철금속 등의 금속제품의 판매가 증가되고 있으며, 이러한 금속제품은 포장되어 보관 또는 운반된다. 금속제품의 운반 또는 보관시 금속제품은 부식이 야기되기가 쉬우며, 이로 인한 공업적 손실이 증대되고 있다.As the metal industry develops, sales of metal products such as ferrous or nonferrous metals are increasing, and these metal products are packaged and stored or transported. When transporting or storing metal products, metal products are easily corroded, and industrial losses are increasing.

종래의 경우 금속제품의 부식발생을 방지하기 위해 실리카겔과 같은 흡습제나 기화성 방청제를 사용하여 왔다.In the conventional case, in order to prevent the occurrence of corrosion of metal products, a desiccant such as silica gel or a vaporizable rust inhibitor has been used.

실리카겔은 수분 흡수율이 자기 중량의 20~30% 정도밖에 되지 못하며 또한 공업용의 경우 산도가 낮으므로 폐기시 토양의 산성화를 가져오게 되어 각종 환경오염을 유발하거나 생태계에 악영향을 미치는 문제점을 가지고 있다.Silica gel has a water absorption rate of only about 20 to 30% of its own weight, and in the case of industrial use, since it has a low acidity, it causes acidification of the soil when discarded, causing various environmental pollution or adversely affecting the ecosystem.

또한, 기화성 방청제의 경우 방청효과는 좋으나, 흡습기능은 미비하여 고온, 다습한 환경하에서의 사용시 수분에 대한 용해성이 높으므로 사용시 금속제품의 표면에 용해된 잔유물이 침착하여 사용 후에는 반드시 세정작업이 필요하며, 도장력의 약화를 초래하는 문제점을 가지고 있다.In addition, in the case of a vaporizable rust inhibitor, the rust prevention effect is good, but the moisture absorption function is insufficient, so it has high solubility in moisture when used in a high temperature and high humidity environment. And, it has a problem that causes weakening of the coating power.

이를 해결하기 위해 흡습제에 기화성 방청제를 혼합한 기화성 방청 흡습제가 개발되었다.To solve this problem, a vaporizable rust preventive desiccant was developed in which a vaporizable rust inhibitor was mixed with a desiccant.

이러한 기화성 방청 흡습제의 선행기술로는, 대한민국 공개특허공보 10-2009-0107296호 "기화성 방청기능을 가진 흡습제 제조방법"(공개일자 : 2009.10.13)과, 대한민국 공개특허공보 10-2016-0121855호 "방청흡습제 제조방법 및 그에 의하여 제조되는 방청흡습제"(공개일자 : 2016.10.21)가 개시되어 있다.As prior art of such a vaporizable rust preventive desiccant, Korean Patent Laid-Open Publication No. 10-2009-0107296 "Method of manufacturing a desiccant having a vaporizable rust preventive function" (published date: 2009.10.13) and Korean Patent Laid-Open No. 10-2016-0121855 "A method of manufacturing a rust-preventing desiccant and a rust-preventing desiccant manufactured thereby" (published date: 2016.10.21) is disclosed.

상기 종래의 선행기술인 기화성 방청 흡습제의 경우, 흡습제로 제올라이트, 실리케이트 또는 벤토나이트를 사용하였으나, 이러한 흡습제만을 사용하는 경우, 기화성 방청 흡습제의 점도 조절이 쉽지 않고, 오히려 점도가 낮아 부직포에 기화성 방청 흡습제를 포장하여 사용하는 경우, 부직포 외부로 기화성 방청 흡습제가 유출되는 문제점이 있다.In the case of the conventional prior art vaporizable rust-preventing desiccant, zeolite, silicate, or bentonite was used as the desiccant, but when only such a desiccant is used, it is not easy to adjust the viscosity of the vaporizable rust-preventing desiccant. When used, there is a problem in that the vaporizable rust-preventing desiccant leaks out of the nonwoven fabric.

또한, 종래의 기화성 방청 흡습제의 경우, 산소흡습제를 사용하지 않아, 금속류 제품 주변의 산소 흡수 기능이 좋지 못하여 방청력이 감소되는 문제점을 가지고 있다. In addition, in the case of the conventional vaporizable rust preventive desiccant, since an oxygen absorbent is not used, the oxygen absorbing function around metal products is poor, and the rust preventive power is reduced.

또한, 기화성 방청 흡습제는 흡습제 1000중량부에 대해서 벤조산나트륨은 100중량부 내지 150중량부이고, 하이드로퀴논은 20중량부 내지 35중량부이고, 소르빈산칼륨은 20중량부 내지 35중량부이고, 산화아연은 20중량부 내지 30중량부이고, 옥탄산은 30중량부 내지 45중량부이고, 아황산나트륨은 50중량부 내지 70중량부이고, 벤조트리아졸은 50중량부 내지 70중량부로 구성된다.In addition, the vaporizable rust-preventing desiccant is 100 to 150 parts by weight of sodium benzoate, 20 to 35 parts by weight of hydroquinone, and 20 to 35 parts by weight of potassium sorbate, based on 1000 parts by weight of the desiccant, and zinc oxide.

또한, 흡습제 형성단계(S10)에서 흡습제의 점도는 170,000cP 내지 200,000cP 이고, 흡습률은 적어도 200% 이상을 갖도록 형성한다.In addition, in the desiccant forming step (S10), the viscosity of the desiccant is 170,000 cP to 200,000 cP, and the moisture absorption rate is formed to have at least 200% or more.

상기의 구성에 따른 본 발명인 기화성 방청 흡습제 제조방법의 동작은 다음과 같다.The operation of the method for manufacturing a vaporizable rust preventive desiccant according to the present invention according to the above configuration is as follows.

흡습제 형성단계(S10)는 통상적으로 흡습제로 알려진 염화칼슘(CaCl2)을 사용하고, 염화칼숨을 부직포(Breath Paper)에 포장하여 사용시 내용물이 부직포 외부로 유출되지 않도록 일정 농도의 점도를 갖도록 응결제인 잔탄검(Xanthan Gum)을 혼합한다.In the desiccant formation step (S10), calcium chloride (CaCl 2 ), which is commonly known as a desiccant, is used, and when the calcium chloride is wrapped in a nonwoven fabric (Breath Paper) and used, xanthan is a coagulant to have a viscosity of a certain concentration so that the contents do not leak out of the nonwoven fabric. Mix the gum (Xanthan Gum).

이때, 응결제인 잔탄검의 혼합시 잔탄검을 적게 혼합하는 경우, 점도가 낮아지게 되어 내용물이 부직포 외부로 유츨되며, 응결제인 잔탄검을 너무 많이 혼합하게 되면 수분 흡습률이 떨어지게 되고, 응결제의 가격이 비싸 비경제적이다.At this time, when a small amount of xanthan gum is mixed when mixing xanthan gum as a coagulant, the viscosity is lowered and the contents are spilled out of the nonwoven fabric, and if too much xanthan gum, a coagulant, is mixed, the moisture absorption rate decreases, and the cost of the coagulant is expensive. It is uneconomical.

다음의 표 1과 표 2는 본 발명의 흡습제 형성단계(S10)에서 염화칼슘과 응결제인 잔탄검을 일정 비율의 중량비로 혼합한 흡습제의 비율별 점도와 흡습률을 관찰한 것이다.The following Tables 1 and 2 show the viscosity and moisture absorption of a desiccant obtained by mixing calcium chloride and xanthan gum as a coagulant at a certain weight ratio in the desiccant forming step (S10) of the present invention.

상기 표 1과 표 2는 섭씨 25도에서 수분 90%, 168시간 동안 염화칼슘과 잔탄검으로 구성된 흡습제를 각기 다른 중량비로 혼합한 후, 혼합한 흡습제 100g을 부직포로 포장하여 각각에 대한 점도와 흡습률을 측정한 것이다.Tables 1 and 2 show that after mixing a desiccant composed of calcium chloride and xanthan gum at different weight ratios for 90% moisture at 25 degrees Celsius and 168 hours, 100 g of the mixed desiccant was wrapped in a nonwoven fabric, and the viscosity and moisture absorption for each Is measured.

상기 표 1에서 나타난 바와 같이, 흡습제의 점도가 170,000cP ~ 200,000cP 이고, 흡습률은 적어도 200% 이상인 흡습제를 부직포에 포장하여 사용하는 경우 수분을 흡습하더라도 물기가 발생하지 않고 흡습제는 젤(gel) 상태로 유지할 수 있어, 부직포 내부의 내용물이 외부로 유츨되지 않는 것을 확인할 수 있다.As shown in Table 1, when a desiccant with a viscosity of 170,000 cP ~ 200,000 cP and a moisture absorption rate of at least 200% is packaged in a nonwoven fabric, moisture does not occur even when moisture is absorbed, and the desiccant is a gel. It can be maintained in a state, so it can be confirmed that the contents of the nonwoven fabric do not leak to the outside.

따라서, 흡습제 형성단계(S10)에서 염화칼슘과 잔탄검을 중량비 7:3 비율로 혼합한 흡습제를 선택하여 사용한다.Therefore, in the desiccant forming step (S10), a desiccant obtained by mixing calcium chloride and xanthan gum in a weight ratio of 7:3 is selected and used.

다음의 표 3은 1000ml beaker에 증류수 100ml를 넣고 루사이트에 상기 샘플1 내지 샘플8 각각에 대해서 100g을 부직포로 포장한 후 열봉합하여 밀봉된 각각의 부직포를 섭씨 50도, 습도 90%에서 168시간동안 오븐에 넣은후 수분 흡습률을 측정한 것이다.Table 3 below shows that 100 ml of distilled water was added to a 1000 ml beaker, and 100 g of each of the samples 1 to 8 was wrapped in a non-woven fabric in lucite, and then heat-sealed to seal each non-woven fabric at 50 degrees Celsius and 90% humidity for 168 hours. The moisture absorption rate was measured after putting it in the oven.

상기 표 3의 수분 흡습률에서 샘플4의 경우 수분 흡습률이 200% 미만으로 측정되었고, 나머지 샘플들에 대해서는 수분 흡습률은 200%이상인 것으로, 이는 염화칼슘(CaCl2)과 응결제인 잔탄검(Xanthan Gum)을 7:3으로 혼합하였으므로, 앞에 표 1에서와 같이 200% 이상의 수분 흡습률을 얻을 수 있으며, 샘플 4의 경우에는 기화성 방청제로 사용된 산화아연(Zinc Oxide)은 수분을 흡수하지 못하므로, 수분 흡습률이 다른 샘플들에 비해 상대적으로 낮은 것을 알 수 있다.In the moisture absorption rate of Table 3, in the case of Sample 4, the moisture absorption rate was measured to be less than 200%, and the moisture absorption rate for the remaining samples was 200% or more, which is calcium chloride (CaCl 2 ) and xanthan gum (Xanthan) as a coagulant. Gum) was mixed at 7:3, so it is possible to obtain a moisture absorption rate of 200% or more as shown in Table 1 above, and in the case of Sample 4, zinc oxide used as a vaporizable rust inhibitor cannot absorb moisture. , It can be seen that the moisture absorption rate is relatively low compared to other samples.

다음의 표 4는 상기 샘플1 내지 샘플8 각각에 대해서 100g을 부직포로 포장한 후 열봉합하여 밀봉된 각각의 부직포를 200리터의 용기에 넣고, 섭씨 25도 실온에서 48시간 경과 후 산소측정기를 사용하여 용기 내부의 산소 농도를 측정한 것이다.Table 4 below shows that 100g of each of Samples 1 to 8 was wrapped in a nonwoven fabric, then heat-sealed and sealed in a 200 liter container, and an oxygen meter was used after 48 hours at room temperature at 25 degrees Celsius. Thus, the oxygen concentration inside the container was measured.

상기 표 4의 샘플7을 제외한 나머지 샘플들의 경우, 용기 내의 산소 농도가 초기치 18.9%에서 16.1% 또는 16.2%로 감소되는데 반해, 샘플7의 경우 용기 내의 산소 농도는 18.9%이다.In the case of the samples other than Sample 7 in Table 4, the oxygen concentration in the container is reduced from 18.9% to 16.1% or 16.2% from the initial value, whereas in the case of Sample 7, the oxygen concentration in the container is 18.9%.

이는 샘플7의 기화성 방청 흡습제는 산소흡습제 역활을 하는 아황산나트륨과 벤조트리아졸을 혼합하지 않지 않아, 용기 내부의 산소를 제대로 흡습하지 못해 용기 내부의 산소 농도가 다른 샘플들에 비해 높은 것을 확인할 수 있다.It can be seen that the vaporizable rust-preventing desiccant of Sample 7 does not mix sodium sulfite and benzotriazole, which act as oxygen absorbents, so it does not properly absorb oxygen inside the container, so the oxygen concentration inside the container is higher than that of other samples. .
