［産業上の利用分野］
本発明は切削、研削加工時に使用する水溶性切削油剤が
腐敗した時に発生する悪臭を除去する方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for removing the bad odor generated when a water-soluble cutting fluid used during cutting and grinding goes bad.
［従来の技術］
切削油剤は防火対策、作業環境の改善、省資源、油剤コ

、腐敗し易いため、種々の好ましくない変化を起こす。[Prior Art] Water-soluble cutting fluids are being used instead of water-insoluble cutting fluids from the viewpoints of fire prevention measures, improvement of working environment, resource saving, and cost of oil. Although aqueous solutions of water-soluble cutting fluids have many advantages over water-insoluble ones, they tend to breed bacteria and fungi and are susceptible to putrefaction, resulting in various undesirable changes.

敗が進行して、悪臭の発する液は、更新を余儀なくされ
る。There are various types of bacteria and mold, including aerobic bacteria, anaerobic bacteria, cocci, rods, spore bacteria, and yeast. In particular, the generation of hydrogen sulfide and the like by anaerobic sulfate-reducing bacteria has an adverse effect on the working environment due to its foul odor, making it difficult to carry out work. On days such as the day after a holiday, anaerobic bacteria increase due to lack of oxygen in the liquid, making the odor even worse. Due to the growth of other bacteria and mold, decomposition progresses and the foul-smelling liquid must be replaced.

よる悪臭を直接除去する方法については、研究は進んで
いない。Conventionally, as a method to prevent spoilage of water-soluble cutting fluids, a few percent of chemicals such as 0-phenylphenol, tetrachlorophenol, P-chloro-m-xylenol, hexahydrotriazine, and tribromosalicylanilide are added to the cutting fluid in advance. However, research has not progressed on methods to directly remove the foul odor caused by rotting water-soluble cutting fluids.

成した。[Problems to be Solved by the Invention] The present inventor completed the present invention as a result of repeated research to develop a method for efficiently removing the bad odor generated from putrid water-soluble cutting fluid.
［問題を解決するための手段］
即ち、本発明は腐敗した水溶性切削油剤に有機過酸を主
体とする製剤を添加し悪臭を除去する方法に間する。[Means for Solving the Problems] That is, the present invention provides a method for removing bad odors by adding a preparation mainly containing an organic peracid to a spoiled water-soluble cutting fluid.

るためである。The organic peracids used in the present invention include performic acid, peracetic acid, perpropionic acid, perisobutyric acid, perpivalic acid, perethylhexanoic acid, perneodecanoic acid, perbenzoic acid, m-chloroperbenzoic acid, p- - ditroperbenzoic acid, perphthalic acid, and metal salts thereof, or methyl, ethyl, propyl,
There are isopropyl and butyl esters. The reason for the spoilage of aqueous solutions of water-soluble cutting fluids is that they contain carbohydrates, minerals, and proteins that are food sources for bacteria and mold, and the liquid temperature is suitable for the growth of bacteria and mold. It's for a reason.
有機過酸は 悪臭の原因物質である硫化水素、及びメル
カプタンと反応しこれを無臭の硫酸とする。水溶性切削

化水素、及びメルカプタンと反応させ悪臭を除去するこ
とが出来る。水溶性切削油剤は通常１０〜１００倍に水
で希釈し、水溶液として使用する。The organic peracid reacts with hydrogen sulfide and mercaptan, which are the substances responsible for bad odors, to form odorless sulfuric acid. By adding a very small amount of organic peracid to a water-soluble cutting fluid, it is possible to react with hydrogen sulfide and mercaptan and remove bad odors. Water-soluble cutting fluids are usually diluted 10 to 100 times with water and used as an aqueous solution.
添加量は水溶性切削油剤の水溶液に対して２０ｐｐｍ以
上で悪臭を除去することが出来た。しかし１１０００ｐ
ｐを超えて添加することは勿論悪臭除去作用はあるが逆
に水溶液は有機過酸臭のため作業環境に好ましくない影
響与え実用に適しなくなる場合もある。添加量は２０〜
１０１０００ｐｐ好ましくは１１００ｐｐ〜２００ｐｐ
ｍである。実用上は、作業環境、液温によるが、液量に
対し１１００ｐｐ程度の有機過酸を添加することにより
悪臭を除去することが出来る。When the amount added was 20 ppm or more based on the aqueous solution of water-soluble cutting fluid, bad odors could be removed. But 11000p
Adding more than p will of course have the effect of removing bad odors, but conversely, the aqueous solution will have an unfavorable effect on the working environment due to the organic peracid odor, and may become unsuitable for practical use. The amount added is 20~
101000pp preferably 1100pp to 200pp
It is m. In practice, it is possible to remove bad odors by adding about 1100 pp of organic peracid to the amount of liquid, although it depends on the working environment and liquid temperature.

The aqueous solution was put into a flask with an air cooler and the flask was immersed in a constant temperature water bath at 35° C. for 3 days to spoil the aqueous solution. To this putrid aqueous solution, various amounts of a preparation containing peracetic acid, ie, 15% peracetic acid, 14% hydrogen peroxide, 28% acetic acid, and the remaining water were added, and the effectiveness was determined based on the odor. . The results are shown in Table 1.

Increase in costs due to disposal can be prevented. In addition, after the organic peracid acts, it decomposes into organic acid, water, and oxygen, and becomes a substance that is safe and harmless to the human body.
