공업용으로 사용되는 금속 부품들은 그 가공공정 중에 그리이스, 광물유, 압연유, 절삭유, 방청유, 금속가루와 같은 다양한 이물질들이 혼입된다. 이러한 이물질은 금속 부품을 이용한 완제품의 조립 이전에 완벽하게 제거되어야 하며, 이물질의 제거가 충분히 이루어지지 않았을 경우에 정밀성 저하, 오염 문제와 같은 여러 가지 문제점을 야기할 수 있다.Metal parts used for industrial use include various foreign substances such as grease, mineral oil, rolling oil, cutting oil, rust preventive oil and metal powder during the processing. Such foreign matter should be completely removed prior to assembly of the finished product using metal parts, and if the removal of the foreign matter is insufficient, it may cause various problems such as deterioration of precision and contamination.
종래에는 정밀 금속 부품에 부착된 유기물 및 무기물로 구성된 오염을 제거하는데 염화 불화 탄소(chloro fluoro carbon; CFC) 및 유기염소계를 사용하였다. 상기 CFC 및 유기염소계는 독성이 없고, 화학적 안정성 및 열역학적인 특성이 우수하여 전 산업 분야에 걸쳐 널리 사용되어 왔다. 그러나, 상기 물질들이 지구 성층권의 오존층을 파괴하는 물질로 밝혀짐에 따라 지구환경의 보호를 위해 1987 년 몬 트리올 의정서 협약의 체결과 동시에 선진국을 비롯한 여러 나라에서는 1996 년부터 이러한 물질의 사용을 전면규제 하였으며, 개발도상국의 경우에는 2010 년 이후부터 사용금지 품목으로 결정하였다.Conventionally, chloro fluorocarbon (CFC) and an organic chlorine system have been used to remove contamination composed of organic and inorganic substances attached to precision metal parts. The CFCs and organochlorine systems are non-toxic, have excellent chemical stability and thermodynamic properties, and thus have been widely used throughout the industry. However, as these substances have been identified as destroying the ozone layer in the global stratosphere, in addition to the conclusion of the Montreal Protocol of 1987 in order to protect the global environment, many countries, including developed countries, have been using these substances since 1996. In the case of developing countries, it was decided to be banned after 2010.
이에 따라 CFC 및 유기염소계를 대체할 세정제로 오존층 파괴의 위험이 없는 수계 세정제가 제시되었다. 일반적으로 수계 세정제는 알칼리 빌더, 비이온 계면활성제, 비이온 및 음이온 계면활성제의 혼합물, 및 킬레이트를 주성분으로 포함한다. 상기 수계 세정제의 알칼리 빌더로는 수산화 나트륨, 수산화 칼륨, 오르토 규산 나트륨, 메타 규산나트륨, 또는 인산 나트륨을 사용할 수 있으며, 상기 알칼리 빌더와 동물유 및 유지의 비누화 반응을 통하여 이물질을 제거하게 된다. Accordingly, a water-based cleaner that has no risk of destroying the ozone layer has been proposed as a cleaner to replace CFCs and organochlorine systems. Aqueous cleaners generally comprise, as main components, alkali builders, nonionic surfactants, mixtures of nonionic and anionic surfactants, and chelates. As the alkali builder of the aqueous cleaner, sodium hydroxide, potassium hydroxide, sodium ortho silicate, sodium metasilicate, or sodium phosphate may be used, and foreign substances are removed through saponification of the alkali builder with animal oil and fats and oils.
상기 계면활성제는 이물질에 대해 침투, 유화, 및 분산작용을 통해 이물질을 제거하는데 사용되며, 비이온성 계면활성제 단독으로 또는 비이온과 음이온 계면활성제를 병용하여 사용하고 있다. The surfactant is used to remove foreign substances through permeation, emulsification, and dispersion of foreign substances, and is used alone or in combination with nonionic surfactants.
상기 킬레이트제는 음이온 계면활성제가 공업용수 중의 칼슘, 마그네슘 등의 경수 성분에 의해 계면활성 작용이 저하되는 것을 방지하기 위해서, 그리고 금속 부품의 가공공정에서 발생하는 금속분의 제거하기 위해 사용한다. The chelating agent is used to prevent the anionic surfactant from degrading the surfactant activity due to hard water components such as calcium and magnesium in industrial water, and to remove metal powder generated in the metal parts processing step.
이 같은 종래의 알칼리 세정제를 무기물과 비이온 계면활성제를 이용하여 일액형의 수용액을 제조할 때, 고농도인 무기물의 염석 작용에 의해 상분리가 일어난다. 염석 작용에 의한 상분리를 방지하기 위한 방법으로 분말 또는 무기물과 계면활성제를 나누어 판매 사용하는 방법을 택하기도 한다. When the conventional alkaline detergent is prepared using an inorganic substance and a nonionic surfactant to prepare a one-component aqueous solution, phase separation occurs by the salting action of a high concentration of the inorganic substance. As a method for preventing phase separation due to salting action, a powder or inorganic substance and a surfactant may be used for sale.
그러나, 무기물과 계면활성제를 소량 함유하는 경우에 알칼리 세정제의 안정 성은 확보할 수 있지만, 세정력, 및 지속력이 떨어진다는 단점이 있다. 또한, 음이온 계면활성제를 사용할 경우 세척성은 뛰어난 반면 기포 발생이 많아 산업 현장에서 작업성이 좋지 않은 단점을 지니고 있다.However, in the case of containing a small amount of inorganic matter and surfactant, the stability of the alkaline cleaner can be secured, but there is a disadvantage in that the cleaning power and the sustaining power are poor. In addition, when anionic surfactants are used, the washability is excellent, but a lot of bubbles are generated, which has a disadvantage of poor workability in an industrial site.
상기와 같은 종래 기술에서의 문제점을 고려하여, 본 발명은 저온에서의 상안정성이 우수한 고농축 알칼리 세정제 조성물을 제공하는 것을 목적으로 한다.In view of the problems in the prior art as described above, an object of the present invention is to provide a highly concentrated alkaline detergent composition excellent in phase stability at low temperatures.

Next, the time taken for the solutions to be 100% degreased was measured.
(노화성)(Aging)
상기 실시예 1 내지 4, 및 비교예 1 내지 4의 알칼리 세정제 조성물을 희석시켜 3% 용액 1 ℓ에 오일(한국 하우톤 클린-420 방청유)을 10 ㎖(10,000 ppm), 및 7 ㎝ ×12 ㎝ ×2 ㎜의 금속시편을 1 분 동안 초음파 세척을 실시하였다. 초음파 세척 뒤의 시편에 대하여 물퍼짐의 면적을 육안으로 판별하였다.10 ml (10,000 ppm) of oil (Korean Hawthorne Clean-420 rust preventive oil) and 1 cm of 3% solution were diluted by diluting the alkali cleaning composition of Examples 1 to 4 and Comparative Examples 1 to 4, and 7 cm x 12 cm Ultrasonic cleaning of metal specimens of 2 mm was performed for 1 minute. The area of water spread was visually determined on the specimen after ultrasonic cleaning.
또한, 오일의 양을 15㎖(15000 ppm)로 한 것을 제외하고는 상기한 노화성 실험과 동일하게 수행하여, 각 조성물들의 물퍼짐 면적을 관찰하였다.In addition, except that the amount of oil to 15ml (15000 ppm) was carried out in the same manner as the aging test described above, the water spread area of each composition was observed.
상기 실시예 1 내지 4, 및 비교예 1 내지 4의 알칼리 세정제 조성물에 대한 성능 평가 결과를 하기 표 2에 기재하였다. The evaluation results of the alkali cleaner compositions of Examples 1 to 4 and Comparative Examples 1 to 4 are shown in Table 2 below.

또한, 상기 실시예 1 내지 4의 알칼리 세정제 조성물은 비교예 1 내지 4의 세정제 조성물에 비하여 100 % 탈지에 소요되는 시간이 짧아 세정능력이 우수함을 확인할 수 있다. In addition, the alkali cleaning composition of Examples 1 to 4 has a short time required for 100% degreasing as compared to the cleaning composition of Comparative Examples 1 to 4 it can be confirmed that the cleaning ability is excellent.
3% 희석 용액으로 시행한 노화성 실험에서도, 상기 실시예 1 내지 4의 알칼리 세정제 조성물이 비교예 1 내지 4의 세정제 조성물에 비하여 노화성이 우수함을 알 수 있다. 특히, 상기 실시예 1 내지 4의 알칼리 세정제 조성물은 오일 노화 10,000 ppm까지 100%의 탈지력을 나타내어, 세정액 사용기간을 증가시킬 수 있음을 알 수 있다.Also in the aging test conducted with a 3% dilution solution, it can be seen that the alkaline cleaning composition of Examples 1 to 4 is superior to the cleaning composition of Comparative Examples 1 to 4. In particular, it can be seen that the alkali detergent composition of Examples 1 to 4 exhibits 100% degreasing power up to 10,000 ppm of oil aging, thereby increasing the service life of the cleaning liquid.
이에 반하여, 상기 비교예 1은 알칼리 빌더의 함량이 10 중량% 미만이므로 저온 안정성은 우수하게 나타나나, 탈지성 및 노화성이 본 발명의 실시예에 비하여 현저하게 저하됨을 확인할 수 있다. 또한, 비교예 2 내지 3은 저온 안정성, 탈지성 및 노화성 모두 낮게 나타났다. On the contrary, Comparative Example 1 has an excellent low temperature stability because the content of the alkali builder is less than 10% by weight, it can be seen that the degreasing and aging properties are significantly lower than the embodiment of the present invention. In addition, Comparative Examples 2 to 3 showed low low temperature stability, degreasing property, and aging.
