Description
본 발명은 수성의 투명 절삭유 조성물에 관한 것이다.The present invention relates to an aqueous transparent cutting oil composition.
절삭유란 금속 재료 등을 절삭할 때 절삭부위 또는 절삭공구부위를 냉각시키고 윤활하게 하여, 공구의 수명을 연장하고 절삭 효율을 높이기 위한 오일을 의미한다. 절삭유는 성상에 따라 크게 유성과 수성으로 나뉜다. 상기 유성 절삭유는 석유계 오일, 광물유 등을 포함하여, 악취가 강하여 작업자에게 두통 및 메스꺼움을 유발하여 작업효율을 떨어뜨리고 안전사고를 유발하는 문제점이 있고, 피부병, 암 등을 유발하는 것을 알려져 있다. 또한, 절삭 작업 후 이들 잔존물을 세정하기 위한 별도의 세정 공정을 수행해야 한다. 절삭유 세정 공정에서 사용되는 세정제에 함유된 용매들은 인체에 강한 독성을 가지며, 인화성이 강하여 화재 위험이 높다. Cutting oil refers to oil that cools and lubricates the cutting area or cutting tool area when cutting metal materials, etc., thereby extending the life of the tool and increasing cutting efficiency. Cutting oil is largely divided into oil-based and water-based depending on its properties. The oil-based cutting oil, including petroleum oil and mineral oil, has a strong odor and causes headaches and nausea in workers, reducing work efficiency and causing safety accidents, and is known to cause skin diseases, cancer, etc. In addition, a separate cleaning process must be performed to clean these residues after the cutting operation. Solvents contained in detergents used in the cutting oil cleaning process are highly toxic to the human body and are highly flammable, raising the risk of fire.
반면, 수성 절삭유는 절삭 작업 후 세정 공정이 수월하고, 인체 독성이 적어 최근사용 빈도가 증가하는 추세이다. 그러나, 현재까지 개발된 수성 절삭유는 절삭유로서 기본적인 기능인 절삭능이 낮을 뿐더러, 절삭 원액와 물을 혼합하여 유화한 후 색깔이 유백색 불투명으로 변하여 절삭 작업시 작업자가 절삭면을 정확히 볼 수 없어 작업 능률이 떨어지고, 안전사고 발생률이 높다는 문제점이 있다. 또한, 수성 절삭유는 물과 혼합한 이후에는 생화학적 안정성이 급격히 저하되어 저장 안정성이 낮다는 문제가 있다.On the other hand, water-based cutting oil is easy to clean after cutting work and has low toxicity to the human body, so the frequency of use is increasing recently. However, the water-based cutting fluids developed to date not only have low cutting performance, which is a basic feature of cutting fluids, but their color changes to milky white and opaque after emulsifying by mixing the cutting fluid with water, so the operator cannot clearly see the cutting surface during cutting work, which reduces work efficiency. There is a problem with the high rate of safety accidents. In addition, water-based cutting oil has a problem of low storage stability because its biochemical stability rapidly decreases after mixing with water.

Transparency was assigned a score of 1 to 10. Specifically, the more transparent the score, the higher the score, and the more opaque the score, the lower the score.
비교예는, 혼합시 혼합물에 가온하지 않은 경우(비교예 1), 약 40℃로 가온한 경우(비교예 2), 약 100℃로 가온한 경우(비교예 3), 성분의 함량을 제조예와 달리한 경우(비교예 4~비교예 11, 표 1 참조)를 사용하였다.In comparative examples, when the mixture was not heated during mixing (Comparative Example 1), when heated to about 40°C (Comparative Example 2), and when heated to about 100°C (Comparative Example 3), the content of the ingredients was calculated as Preparation Example. A case different from (Comparative Example 4 to Comparative Example 11, see Table 1) was used.
그 결과, 본 발명의 경우 투명도가 10점으로 투명하나, 비교예들은 투명도가 낮아 불투명함을 확인할 수 있었다(표 2).As a result, in the case of the present invention, it was confirmed that the transparency was transparent with a score of 10, but the comparative examples were opaque due to low transparency (Table 2).
[실험예 2] 제형 안정성 테스트[Experimental Example 2] Formulation stability test
제조된 본 발명의 희석액과 비교예들을 약 30일 동안 상온에서 보관하면서, 상분리가 발생하는지 여부를 관찰하고 점수화하였다. 상분리나, 부유물이 발생하지 않을 경우 10점 만점을 기준으로 높은 점수를 부여하였고, 상분리 또는 부유물 등이 발생한 경우 제형 안정성이 낮은것으로 보아 낮은 점수를 부여하였다.The prepared diluted solution of the present invention and the comparative examples were stored at room temperature for about 30 days, and whether phase separation occurred was observed and scored. If phase separation or suspended solids did not occur, a high score was given out of 10, and if phase separation or suspended solids occurred, a low score was given because the formulation stability was considered low.
그 결과, 본 발명의 절삭유 희석액의 경우 제형 안정성이 우수한 반면, 비교예들은 제형 안정성이 떨어짐을 확인할 수 있었다(표 3).As a result, it was confirmed that the cutting oil diluent of the present invention had excellent formulation stability, while the comparative examples had poor formulation stability (Table 3).
