본 발명은 방청흡습제 제조방법 및 그에 의하여 제조되는 방청흡습제에 관한 것으로서, 더욱 상세하게는 방청과 흡습을 동시에 수행함으로써 금속제품의 부식을 효과적으로 방지할 수 있는 방청흡습제 제조방법 및 그에 의하여 제조되는 방청흡습제에 관한 것이다. The present invention relates to a method for manufacturing a rust preventive desiccant and to a rust preventive desiccant produced thereby, and more particularly, to a method for manufacturing a rust preventive desiccant capable of effectively preventing corrosion of metal products by simultaneously performing rust prevention and moisture absorption, and a rust preventive desiccant manufactured thereby is about

산업이 발달함에 따라 금속을 재료로 하는 제품들이 생산되고 있으며, 이들 금속제품들은 부식에 취약하기 때문에 부식을 방지하기 위한 방청처리를 하고 있다. 그런데 최근 지구의 온난화로 인하여 온도가 상승하고 기후가 다습해짐에 따라 과거에 행하였던 방청처리보다 더 엄밀한 방청처리가 요구되고 있다. 통상 방청처리는 금속제품을 방청지로 포장하고, 이후 테이핑 또는 밴딩을 함으로써 이루어졌다. 이러한 방청처리를 위한 방청지에 관련된 선행기술이 특허공개번호 10-2001-94902호에 방청지란 명칭으로 개시되어 있다.As the industry develops, products made of metal are being produced, and since these metal products are vulnerable to corrosion, anti-corrosion treatment is used to prevent corrosion. However, as the temperature rises due to the recent global warming and the climate becomes humid, more rigorous rust prevention treatment than the rust prevention treatment performed in the past is required. In general, rust prevention treatment was made by packaging metal products with rust prevention paper, followed by taping or banding. A prior art related to anti-rust paper for such anti-rust treatment is disclosed in Patent Publication No. 10-2001-94902 under the name of anti-rust paper.

그런데 금속제품은 통상적으로 많은 중량이 나가기 때문에, 금속제품을 움직이면서 방청지로 포장한 후 테이핑 또는 밴딩하는 작업이 매우 어려웠고, 또한 포장 및 테이핑/벤딩과정에서 많은 시간이 소요되었다. 특히 방청과정에서 많은 시간이 소요됨으로서, 방청이 완료될때까지 부식환경에 그대로 노출되었다. However, since metal products typically weigh a lot, it was very difficult to tap or bend the metal products after packaging them with rust-preventing paper while moving, and also took a lot of time in the packaging and taping/bending processes. In particular, since it takes a lot of time in the rust prevention process, it was exposed to the corrosive environment until the rust prevention was completed.

또한 금속제품의 운송 및 보관이 완료된 후 금속제품으로부터 분리된 방청지는 재활용이 되지 않기 때문에 소각을 통하여 폐기하였다. In addition, since the rust-preventive paper separated from the metal product after transportation and storage of the metal product is completed cannot be recycled, it was disposed of through incineration.

그런데 방청지를 소각하는 과정에서 다이옥신과같은 독성물질이 발생하여 환경오염의 원인이 되었다. However, toxic substances such as dioxins were generated in the process of incineration of the rust prevention paper, which caused environmental pollution.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 방청과 흡습을동시에 수행함으로써 다습한 환경에서도 방청 효과를 배가할 수 있는 방청흡습제 제조방법 및 그에 의하여 제조되는 방청흡습제를 제공하는 것을 목적으로 한다.
본 발명의 다른 목적은, 방청지의 사용을 배제함으로써 그 방청지를 폐기하는 과정에서 발생될 수 있는 환경오염 원인을 근본적으로 방지할 수 있는 방청흡습제 제조방법 및 그에 의하여 제조되는 방청흡습제를 제공하는 것이다. The present invention was created to solve the above problems, and by performing both rust prevention and moisture absorption at the same time to provide a method for manufacturing a rust preventive desiccant that can double the rust prevention effect even in a humid environment, and to provide a rust preventive desiccant produced thereby do.
Another object of the present invention is to provide a method for manufacturing a rust preventive desiccant that can fundamentally prevent the cause of environmental pollution that may occur in the process of disposing of the rust preventive paper by excluding the use of the rust preventive paper, and a rust preventive desiccant produced thereby.

이하, 본 발명에 따른 방청흡습제 제조방법 및 그에 의하여 제조되는 방청흡습제를 상세히 설명한다. Hereinafter, a method for manufacturing a rust preventive desiccant according to the present invention and a rust preventive desiccant prepared thereby will be described in detail.

본 발명에 따른 방청흡습제를 제조하기 위하여, 인산나트륨(Mono sodium phosphate), 소듐벤조에이트(Sodium Benzoate), 벤조트리아졸(Benzotriazol) 및 붕산(Boric acid)을 혼합하여 방청조성물을 제조하는 단계(S1)를 수행한다. In order to prepare the rust preventive desiccant according to the present invention, sodium phosphate (Mono sodium phosphate), sodium benzoate (Sodium Benzoate), benzotriazole (Benzotriazol) and boric acid (Boric acid) is mixed to prepare a rust preventive composition (S1) ) is performed.

상기 인산나트륨 및 소듐벤조에이트는 질산계통의 성분을 대체할 수 있는 방청성분으로서 금속제품의 부식을 방지하는 방청효과를 발휘하고, 상기 붕산 및 벤조트리아졸은 비철의 부식 또는 변색의 원인이 되는 이산화황 및 수증기를 제거하고 방청 촉매의 역할을 한다.The sodium phosphate and sodium benzoate are rust-preventive components that can replace nitric acid-based components, and exert a rust-preventing effect to prevent corrosion of metal products, and the boric acid and benzotriazole are sulfur dioxide that causes corrosion or discoloration of non-ferrous materials. And it removes water vapor and serves as a rust prevention catalyst.

상기 단계(S1)의 방청조성물에 있어서, 소듐벤조에이트는 인산나트륨 100 중량부를 기준으로 50 내지 1,000 중량부, 바람직하게는 300 내지 500 중량부를 가지고; 벤조트리아졸은 인산나트륨 100 중량부를 기준으로 5 내지 200 중량부, 바람직하게는 50 내지 100 중량부의 조성비를 가지며; 붕산은 인산나트륨 100 중량부를 기준으로 10 내지 400 중량부, 바람직하게는 100 내지 200 중량부인 조성비를 가진다. 상기 단계(S1)에 있어서, 상기한 조성비를 벗어날 경우, 다른 성분과의 적절한 조합이 이루어지지 않게 되어 방청효과가 미비해진다. In the rust preventive composition of step (S1), sodium benzoate has 50 to 1,000 parts by weight, preferably 300 to 500 parts by weight based on 100 parts by weight of sodium phosphate; Benzotriazole has a composition ratio of 5 to 200 parts by weight, preferably 50 to 100 parts by weight, based on 100 parts by weight of sodium phosphate; Boric acid has a composition ratio of 10 to 400 parts by weight, preferably 100 to 200 parts by weight, based on 100 parts by weight of sodium phosphate. In the step (S1), when the composition ratio is out of the above, an appropriate combination with other components is not made and the rust prevention effect is insufficient.

다음, 프로페놀(propanol)과 폴리에틸렌글리콜(Polyethylene glycol)을 혼합하여 유기용제를 제조하는 단계(S2)를 수행한다. 이때 상기 단계(S2)의 유기용제에 있어서, 프로페놀은 인산나트륨 100 중량부를 기준으로 40 내지 200 중량부, 바람직하게는 80 내지 120 중량부의 조성비를 가지고; 폴리에틸렌글리콜(Polyethylene glycol)은 인산나트륨 100 중량부를 기준으로 5 내지 30 중량부, 바람직하게는 10 내지 20 중량부의 조성비를 가진다. Next, a step (S2) of preparing an organic solvent by mixing propanol and polyethylene glycol is performed.

여기서 프로페놀 및 폴리에틸렌글리콜은, 방청조성액과 혼합되어 상온에서 방청조성물이 급격히 기화되는 것을 방지함과 동시에, 금속표면이 산소와의 직접 접촉하는 것을 차단하기 위한 유기막을 형성한다. Here, propphenol and polyethylene glycol are mixed with the anti-rust composition to prevent rapid vaporization of the anti-rust composition at room temperature, and at the same time form an organic film for blocking direct contact of the metal surface with oxygen.

다음, 방청조성물과 유기용제를 혼합하여 방청유기조성액을 제조하는 단계(S3)를 수행한다. 상기 단계(S3)의 방청유기조성액에 있어서, 방청조성물은 그 방청조성물 100 중량부를 기준으로 유기용제 50 내지 1,000 중량부의 조성비를 가진다. Next, a step (S3) of preparing a rust-preventing organic composition by mixing the rust-preventing composition and an organic solvent is performed. In the rust preventive organic composition of the step (S3), the rust preventive composition has a composition ratio of 50 to 1,000 parts by weight of the organic solvent based on 100 parts by weight of the rust preventive composition.

다음, 상기 방청유기조성액에 벤토나이트를 함침시킨 후 교반하는 단계(S4)를 수행한다. 이때 벤토나이트는 방청유기조성액 100 중량부를 기준으로 150 내지 1,000 중량부, 바람직하게는 300 내지 600 중량부의 조성비를 가진다. Next, the step (S4) of stirring after impregnating bentonite in the rust-preventing organic composition is performed. At this time, the bentonite has a composition ratio of 150 to 1,000 parts by weight, preferably 300 to 600 parts by weight, based on 100 parts by weight of the rust preventive organic composition.

상기 벤토나이트는 천연광물로서 흡습율을 높이기 위하여 다공화처리를 수행한다. 이러한 다공화처리는 벤토나이트를 섭씨 700 내지 1,000 도에서 30 내지 60 분 범위에서 열처리한 후 실온에서 냉각시키고, 이후 50 내지 200 메시 크기로 분쇄함으로써 이루어진다. The bentonite is a natural mineral, and porous treatment is performed to increase moisture absorption. The porous treatment is performed by heat-treating bentonite at 700 to 1,000 degrees Celsius for 30 to 60 minutes, cooling it at room temperature, and then pulverizing it to a size of 50 to 200 mesh.

상기 단계(S4)는, 교반용기에 수용된 방청유기조성액에 50 내지 200 메시크기의 벤토나이트를 함침시킨 후, 교반기를 이용하여 고르게 교반함으로써 이루어진다. The step (S4) is made by impregnating the bentonite of 50 to 200 mesh size in the rust-preventing organic composition solution accommodated in the stirring vessel, and then stirring evenly using a stirrer.

한편 단계(S4)는, 벤토나이트와 교반되는 방청유기조성액에 초음파를 인가하는 초음파인가단계(S4-1)를 더 포함할 수 있다. 이러한 초음파인가단계(S4-1)는 교반용기에 설치된 초음파발생기를 통하여 방청유기조성액에 초음파를 인가하는 것이며, 이에 따라 초음파는 벤토나이트의 다공 내부의 공기가 빠져나오게 함과 동시에 그 다공으로 방청유기조성액이 효과적으로 흡수될 수 있도록 한다Meanwhile, the step (S4) may further include an ultrasonic application step (S4-1) of applying ultrasonic waves to the bentonite and the stirred antirust organic composition. This ultrasonic application step (S4-1) is to apply ultrasonic waves to the anti-rust organic composition through the ultrasonic generator installed in the stirring vessel, and accordingly, the ultrasonic waves cause the air inside the pores of the bentonite to escape and at the same time, the anti-rust organic composition liquid through the pores. to be effectively absorbed

다음, 방청유기조성액이 흡수된 벤토나이트를 상온에서 건조함으로써 방청흡습제를 완성하는 단계(S5)를 수행한다.Next, the step (S5) of completing the rust preventive desiccant is performed by drying the bentonite in which the rust preventive organic composition has been absorbed at room temperature.

상기 [표 1]에서 흡습율은, ((방청흡습제의 중량변화) - (방청흡습제 최초의 중량 게의 변화)) × 100으로 계산되면, 예를 들어 72 시간 경과시 방청흡습제의 중량이 142 이 되었다면, 흡습율은 (142 - 100 ) × 100 = 42% 가 된다.In [Table 1], the moisture absorption rate is ((change in weight of rust preventive desiccant) - (change in initial weight of rust preventive desiccant)) × 100, for example, the weight of the rust preventive desiccant is 142 Then, the moisture absorption would be (142 - 100 ) × 100 = 42%.

이와 같이 본 발명에 따르면, 방청과 흡습을 동시에 수행함으로써 별도의 흡습제의 사용을 배제할 수 있고, 다습한 환경에서도 방청 효과를 배가할 수 있다. As described above, according to the present invention, the use of a separate desiccant can be excluded by performing rust prevention and moisture absorption at the same time, and the rust prevention effect can be doubled even in a humid environment.

또한 금속제품의 방청과정에서 방청지의 사용을 배제할 수 있고, 이에 따라 만약 방청지를 사용하였을 때 그 방청지를 폐기하는 과정에서 발생될 수 있는 환경오염 원인을 근본적으로 방지할 수 있다.In addition, it is possible to exclude the use of anti-rust paper in the rust-preventing process of metal products, and accordingly, when the anti-rust paper is used, the cause of environmental pollution that may occur in the process of disposing of the anti-rust paper can be fundamentally prevented.

본 발명은 도면에 도시된 일 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 본 기술 분야의 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
