(Prior Art) Emulsion-type water-soluble cutting fluid is widely used for cutting and cutting metal materials, but it is recognized that it has a drawback that it easily rots. This type of cutting fluid contains mineral oil, animal and vegetable oils, ester oils, and other base oils with surfactants added, and extreme pressure additives with sulfur compounds, chlorine compounds, phosphorus compounds, and other rust inhibitors. It is used for cutting and grinding as an emulsion by making an undiluted solution and dispersing and emulsifying it in water.Since all of these ingredients are suitable nutrient sources for bacteria and mold, it is possible to use various types in this emulsion. It is a natural result that the above microorganisms grow.
The action of such microorganisms destroys the emulsion and
Deteriorates, the rust preventive property deteriorates, and finally a bad odor is emitted, and oil must be changed.

As a countermeasure for this, conventionally, a method by adding various preservatives has been used. For example, Japanese Examined Patent Publication No. 58-5960 discloses that a cation surfactant, palm alkyl dimethyl benzyl ammonium chloride, is added as an antiseptic and a bactericidal agent as a bactericidal agent, and in Japanese Examined Patent Publication No. 58-51039. Discloses the addition of heavy metal metal cobalt as a bactericide. However, these fungicides are Pseudomonas aeruginosa (Pseudomonas aeruginosa), which are resistant to fungicides, among which various microbes that propagate in cutting oils.
The osa) bacterium cannot be completely suppressed by a usual addition amount, and if it is added in an amount that can be completely suppressed, side effects such as increased stimulating property and deterioration of rust preventive property are not preferable.

(Problems to be Solved by the Invention) In the conventional method of suppressing decay of cutting oil by adding a bactericide, when a heavy metal is used as a bactericide, depending on the type and amount of the sterilizer, the stimulability to the human body is increased. If you use a cationic surfactant, it may hinder rust resistance and emulsion stability depending on the type and amount added, and it is difficult to select the type and amount added of bactericide, which causes side effects. In many cases, it cannot be an effective method for suppressing corruption, and this is a problem that needs to be solved.

(Means for Solving Problems) As means for solving such problems, the inventors of the present invention have antibacterial properties in all components constituting cutting oil, and combine them to form an oil agent. The idea was to obtain an emulsion water-soluble cutting fluid with antibacterial properties without relying on the addition of bactericides.

As the base oil, mineral oil, fats and oils, and synthetic oils such as ester oils are generally used. Among them, fats and oils and fatty acid lower alcohol esters which are esters of fatty acids and lower alcohols are easily hydrolyzed and are the main components in the present invention. It is not preferable to do. In the present invention, it has been found that a method of adding a small amount of a fatty acid higher alcohol ester having mineral oil as a main component and having excellent lubricity and relatively little hydrolyzability is suitable. Here, for mineral oil, essentially all refined mineral oils can be used, but as a result of research by the present inventors,
Since refined mineral oil having a sulfur content of 1.0% or more has poor antibacterial properties, refined mineral oil having a sulfur content of 1.0% or less is preferable as a base oil, and refined mineral oil having a sulfur content of 0.5% or less has the best antibacterial property and is the base oil of the present invention. Was found to be the most preferable.

Thus, it was found that a composition containing a base oil, a fatty acid higher alcohol ester, an alicyclic amine ethylene oxide adduct and an alkylamine ethylene oxide adduct can provide an emulsion composition having excellent antibacterial properties and lubricity. However, as a result of further research, it was found that there are problems in the persistence of the cationic activity of the surfactant component of the present invention, that is, the sustainability of the antibacterial property of the component and the compatibility of the above components. Therefore, we have made improvements in this respect as well, but by unintentionally adding the compound of formula (1) and adjusting the compounding ratio of the components to improve the balance, such drawbacks have been improved and antibacterial properties for long-term use have been improved. It has been found that the stability of the cutting oil composition is improved and the compatibility of the cutting oil composition is remarkably improved during long-term storage, and the present invention was completed here.
