Preservatives and anti-mold agents (containing fungicides, etc. are included as constituent components and are manufactured by appropriately mixing them depending on the purpose. Such water-soluble cutting fluids are usually diluted 10 to 100 times with water and used as a coolant. This coolant has performance related to machinability and grindability (for example, improved surface finish accuracy, extended tool life, etc., hereinafter referred to as "-order performance").
and performance related to workability (for example, good rust prevention, resistant to deterioration and easy to manage, harmless to the human body, low foaming, etc.)

きた。Hereinafter, these will be referred to as "secondary performance." ) is required. Among the performances required of coolants, "prevention of microbial deterioration" is particularly important in preventing: - Decrease in primary performance and secondary performance and generation of bad odors due to the progress of coolant decay; - Prevention of mold from coolant. This is very important in order to prevent the deterioration of primary performance and secondary performance and clogging of pipes in the circulation system due to the occurrence of this phenomenon. For this reason, bactericidal agents have traditionally been added to water-soluble cutting fluids for the purpose of preventing microbial deterioration.

、多くの手間や経費がかかるという問題点もあった。However, in the conventional water-soluble cutting fluids mentioned above, the disinfectant may be effective only against specific microorganisms, so it generally lacks versatility, and the disinfectant decomposes or becomes inactive in a short period of time. However, there was a problem that the bactericidal effect was significantly reduced. Furthermore, if a large amount of disinfectant is used, it may cause severe irritation to the skin, causing rough skin or dermatitis, and may have adverse effects on the human body. For this reason, the concentration of the disinfectant must be controlled so that it is always contained in an optimum amount, which poses the problem of requiring a lot of effort and expense.

は満足する効果が得られないのが実情であった。Furthermore, when using the latter special amine, it is widely effective against bacteria and fungi, but among fungi, it has weak antibacterial properties against yeast fungi, and yeast fungi are the culprit. The reality is that no satisfactory effect can be obtained against the deterioration of water-soluble cutting fluids that occurs in the process.

We have discovered that it has extremely good antibacterial properties against a wide range of microorganisms, including fungi, and has the effect of improving cutting performance, and that it significantly improves the microbial deterioration resistance and cutting performance of water-soluble cutting fluids. The invention was completed.

'pcs/unit~lX1O8/1n1, especially comparative example 3.
In addition, regarding the number of filamentous or yeast fungi, the number of filamentous fungi in the sample of Example 4 was 17 pieces/ml!, and all the others were less than 10 pieces/ml. On the other hand, most of the comparative samples showed a significant increase, and after 21 days, the number of filamentous fungi increased significantly from 6X10' to 3X105/ml, and the number of yeast fungi significantly increased from 2X10' to 7X10'/ml. In particular, the number of yeast fungi was large, indicating that the antibacterial properties against yeast fungi were weak.

From Tables 5 and 6, it can be seen that the water-soluble cutting fluid of the present invention has superior microbial deterioration resistance in practical use as well as improved cutting performance compared to conventional water-soluble cutting fluids. Is recognized. That is, even after 6 months had passed, the number of viable bacteria and fungi in the oil preparation of Example 2 were both extremely low, and in particular, the number of fungi was 5×10′/aII! The number is extremely low at 10/rn1 or less, indicating that it is highly effective in antibacterial properties. Furthermore, the precision of the workpiece has improved by about 50% after 6 months.
