Abstract
Description
본 발명은 금속 표면 처리제에 관한 것으로, 보다 상세하게는 세정 및 탈지 효과 및 오염물질의 제거력이 높아 금속 표면의 산화방지 효과를 가지는 금속 표면 처리제 조성물에 관한 것이다.The present invention relates to a metal surface treatment agent, and more particularly, to a metal surface treatment agent composition having a cleaning and degreasing effect and a high removal power of a contaminant to prevent oxidation of a metal surface.
일반적으로, 공업용 금속 표면에는 동식물 유지, 그리이스, 광물유, 압연유, 절삭유, 프레스유 등의 유성 물질 등 오염물질이 부착되어 있고, 또한 금속가루 등이 상기 오염물질에 혼입되어 있는 경우도 있다. 이 오염물질들은 후공정을 통하여 제거해 둘 필요가 있으며, 일반적으로 금속용 알칼리성 세정제(금속 탈지제)로 상기 오염물질을 제거한다.In general, industrial metal surfaces are contaminated with pollutants such as animal or vegetable oil, grease, mineral oil, rolling oil, cutting oil, press oil and other oily substances, and metal powder or the like may be mixed into the contaminants. These contaminants need to be removed through a post-process, and generally the contaminants are removed with an alkaline detergent for metal (metal degreasing agent).
현재 일반적으로 사용 중인 금속 탈지제 조성들을 살펴보면 고농도의 수산화나트륨 및 수산화칼륨을 주제로 조성되어, 도유, 압연유, 절삭유 등의 지방과 결합하여 검화시켜 비누화로 만든 다음 제거하는 메카니즘 제품이 대부분이다. 그러나, 이러한 메커니즘을 사용하는 경우에는 탈지력은 있으나, 완전하게 제거하지 않으면 비누화에 의한 백태현상(white coating)이 발생되는 문제점이 있을 뿐 아니라, 이를 그대로 방치 시간이 경과되면 수산화 물질들이 수분을 흡수하여 금속표면에 산화를 발생시키는 단점이 있었다. 또한, 이를 제거하여 청결하게 하고자 하면 여러 차례 헹굼 작업을 실시해야 되기 때문에 용수의 사용량이 다량으로 소모되는 문제점도 있고 제품 생산의 원단위도 상승되는 문제점도 있었다.Most of the metal degreasing compositions currently in use are composed of high concentrations of sodium hydroxide and potassium hydroxide and are combined with fat such as castor oil, rolling oil and cutting oil to saponify and then remove them. However, when such a mechanism is used, there is a problem of degreasing force, but if not completely removed, white coating due to saponification may occur. In addition, when the time passes, the hydroxide absorbs moisture Thereby causing oxidation on the metal surface. Also, in order to clean the product, it is necessary to rinse the product several times, so that the amount of water consumed is large and the unit cost of product production is also increased.
또한, 현재 사용 중인 금속 탈지제 조성 중 인(P)을 함유한 제품들도 많이 존재하는데, 인(P)을 포함하면 폐수 처리장에서 부영양화 현상이 나타나게 되며 부하가 많이 걸려서 전체적으로 비용(cost) 상승을 야기하게 되는 문제점도 발생하였다.Also, there are many products containing P (P) in the composition of metal degreasing agent currently in use. If phosphorus (P) is included, eutrophication phenomenon appears in the wastewater treatment plant and the load is increased, There has also been a problem.
본 발명은 상기한 종래의 문제점을 해결하기 위하여 세정, 탈지 효과 및 오염물질의 제거력이 우수하여 금속 표면의 산화방지, 백태현상방지 효과를 가지고 수질환경의 녹조 발생 및 부영양화를 억제하는 금속 표면 처리제를 제공하는 것을 목적으로 한다.Disclosure of the Invention The present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a metal surface treatment agent having an effect of preventing oxidation and prevention of whitening of a metal surface, The purpose is to provide.

Particularly, the use of EDTA in the present invention is advantageous in that the production cost is low and the dispersibility of metal ionic strength is strong.
또한 본 발명의 활성 킬레이트제는 전체 조성물 100중량부를 기준으로 5 ~ 6 중량부, 바람직하게는 5.5 중량부를 사용할 수 있다. 5 중량부 미만으로 사용하면 피세척물에서 분산되거나 용해되었던 오염물질들이 피세척물 금속표면에 재 부착되는 문제점이 발생할 수 있고, 6 중량부를 초과하면 생산 원단위의 상승으로 공급 측면에서 약세를 면하기 어려운 문제점이 발생할 수 있다.The active chelating agent of the present invention may be used in an amount of 5 to 6 parts by weight, preferably 5.5 parts by weight, based on 100 parts by weight of the total composition. If it is used in an amount less than 5 parts by weight, contaminants which have been dispersed or dissolved in the material to be washed may be reattached to the surface of the object to be cleaned. If the amount is more than 6 parts by weight, A difficult problem may arise.

If it is used in an amount of less than 68.5 parts by weight, the concentration of the substance may be increased, and if it exceeds 76 parts by weight, the removal of the fat may be weakened.
본 발명의 금속 표면 처리제 조성물의 바람직한 예를 구체적으로 설명하면, 전체 조성물 100중량부를 기준으로 EDTA 5 ~ 6중량부, 계면활성제 2 ~ 3중량부, 구연산 나트륨 3 ~ 4 중량부, 메타규산소다 8 ~ 20 중량부, 수산화칼륨 0.5 ~ 1 중량부, BTG 3 ~ 4 중량부, 구연산 2.5 ~ 3.5 중량부, 증류수 68.5 ~ 76 중량부로 포함되는 것을 특징으로 하는 금속 표면 처리제일 수 있다.A preferable example of the metal surface treatment composition of the present invention is specifically exemplified by 5 to 6 parts by weight of EDTA, 2 to 3 parts by weight of a surfactant, 3 to 4 parts by weight of sodium citrate, 8 parts by weight of sodium metasilicate 8 To 20 parts by weight, potassium hydroxide 0.5-1 parts by weight, BTG 3-4 parts by weight, citric acid 2.5-3.5 parts by weight and distilled water 68.5 76 parts by weight.

뿐만 아니라, 본 발명의 금속 표면 처리제는 수산화칼륨(KOH)이 고농도로 포함되는 종래의 금속표면 처리제, 탈지제들과 다르게 수산화칼륨(KOH)이 저농도로 포함되기 때문에, 탈지력이 우수할 뿐 아니라 금속으로부터 완전하게 제거하는 것이 가능하여 비누화에 의한 백태현상(white coating)을 예방할 수 있다는 점에서도 우수하다. 또한, 금속 표면으로부터 처리제를 제거하기 위해 실시하는 헹굼 작업의 횟수도 종래의 처리제의 경우보다 더 적게 필요하므로, 헹굼작업에 소요되는 용수의 사용량도 줄일 수 있다는 점에서도 우수하다. In addition, since the metal surface treatment agent of the present invention contains potassium hydroxide (KOH) at a low concentration in contrast to conventional metal surface treatment agents and degreasing agents, which contain potassium hydroxide (KOH) at a high concentration, It is excellent in that white coating due to saponification can be prevented. In addition, since the number of rinsing operations performed to remove the treating agent from the metal surface is less than that of the conventional treating agent, it is also excellent in that the amount of the water used for the rinsing operation can be reduced.
뿐만 아니라, 본 발명의 금속 표면 처리제는 인(P) 함유량이 낮아, 종래에 인(P)을 다량 함유하는 금속 표면 처리제에 비하여 부영양화 현상이 현저히 줄어들게 되므로 전체적으로 비용(cost) 절감 효과도 얻을 수 있다.In addition, since the content of phosphorus (P) is low in the metal surface treatment agent of the present invention, the phenomenon of eutrophication is remarkably reduced compared to a metal surface treatment agent which conventionally contains phosphorus (P) in a large amount, .
본 발명의 금속 표면 처리제는 pH 12.0 ± 0.5의 특징을 가진다. 이는 종래의 금속 표면 탈지제들에 비하여 더 낮은 pH를 가지는 것으로서, 취급과 작업안전성 측면에서 장점을 가질 수 있다. The metal surface treatment agent of the present invention has a pH of 12.0 ± 0.5. This has a lower pH than conventional metal surface degreasing agents and can have advantages in handling and operational safety.
또한, 본 발명의 금속 표면 처리제는 고형분(%) 15 ~ 20%의 특징을 가진다. 이는 종래의 금속 표면 탈지제들에 비하여 더 낮은 고형분(%)를 가지는 것으로서, 폐수처리 비용을 낮추는 장점을 가질 수 있다. In addition, the metal surface treatment agent of the present invention has a solid content (%) of 15 to 20%. This has the advantage of lowering the cost of wastewater treatment, as it has lower solids (%) than conventional metal surface degreasing agents.

본 발명의 금속 표면 처리제에 포함되는 수산화칼륨(KOH) 함량이 약 5% 미만에 해당한다(도 2). 수산화칼륨(KOH) 함량이 5%이상이 되면 유독물에 해당하게 되어 유해화학물질관리법에 준하여 환경청의 관리, 감독을 받아야 하는데, 본 발명의 금속 표면 처리제는 수산화칼륨(KOH) 함량이 5% 미만이므로 유독물에 해당하지 않는다.The content of potassium hydroxide (KOH) contained in the metal surface treatment agent of the present invention is less than about 5% (FIG. 2). When the content of potassium hydroxide (KOH) is 5% or more, it becomes a toxic substance and it is required to be managed and supervised by the Environmental Agency according to the Toxic Chemicals Control Act. The potassium hydroxide (KOH) content of the metal surface treatment agent of the present invention is less than 5% It is not toxic.
본 발명의 금속 표면 처리제에 포함되는 수산화칼륨(KOH) 함량이 약 5% 미만에 해당한다(도 2). 수산화칼륨(KOH)이 함량이 5%이상이 되면 유독물에 해당하게 되어 유해화학물질관리법에 준하여 환경청의 관리, 감독을 받아야 하는데(도 5 참고), 본 발명의 금속 표면 처리제는 수산화칼륨(KOH)이 함량이 5% 미만이므로 유독물에 해당하지 않는다.The content of potassium hydroxide (KOH) contained in the metal surface treatment agent of the present invention is less than about 5% (FIG. 2). When the content of potassium hydroxide (KOH) is 5% or more, it corresponds to a toxic substance, and it is required to be managed and supervised by the Environmental Agency according to the Toxic Chemicals Control Act (see FIG. 5) This content is less than 5%, so it is not toxic.
도 5에 기재된 바와 같이, 수산화칼륨(KOH, Potasium hydroxide)을 5% 이상 함유한 혼합물은 환경청의 규제대상 물질에 해당하게 된다 (출처-국립환경과학원 화학물질 정보시스템).As shown in FIG. 5, a mixture containing 5% or more of potassium hydroxide (KOH) corresponds to a substance to be regulated by the Environment Agency (source: Chemical Information System of National Institute of Environmental Science).
또한, 본 발명의 금속 표면 처리제의 구성성분 함량을 측정한 결과 인(P)에 해당하는 구성성분 함량 값이 단독으로 나타나지 않아 인(P)의 함유량이 낮은 것을 알 수 있다(도 2). 이에 따라, 폐수 처리장에서 부영양화 현상이 줄어들게 되어 전체적으로 비용(cost) 절감 효과도 얻을 수 있다. In addition, as a result of measuring the content of constituent components of the metal surface treatment agent of the present invention, it can be seen that the content of phosphorus (P) is low because the component content value corresponding to phosphorus (P) does not appear alone. As a result, the eutrophication phenomenon is reduced in the wastewater treatment plant, and the cost reduction effect can be obtained as a whole.
