The present invention relates to a water-soluble cutting and grinding fluid, and particularly a water-soluble cutting and grinding fluid that contains an alkali metal salt or amine salt of a ricinoleic acid polycondensate and has excellent machinability, grindability, antifoaming properties, and other various performances. This is what we provide. (Prior Art) Conventionally, compositions containing chlorine and sulfur, or compositions containing an alkali metal salt or amine salt of a higher carboxylic acid have been frequently used as water-soluble cutting and grinding fluids. Although these compositions have excellent cutting and grinding properties, they have the following drawbacks. (1) There is a strong odor. In particular, those containing sulfur-based extreme pressure additives have a pronounced odor. (2) Perishable. Items containing sulfur-based extreme pressure additives are particularly susceptible to spoilage. (3) Easily deteriorated. It is susceptible to deterioration during use, especially a decrease in rust prevention properties. (4) Easy to foam. This tendency is particularly noticeable when using salts of higher fatty acids. (Objective of the present invention) In view of the above-mentioned current situation, it is an object of the present invention to provide a cutting and grinding fluid that has excellent machinability and grindability, is odorless, is resistant to rotting, is resistant to deterioration, and has good antifoaming properties. As a result of extensive research to achieve this objective, the present inventors have found that a composition containing an alkali metal salt or amine salt of a ricinoleic acid polycondensate is excellent as a water-soluble cutting and grinding fluid. The present invention has been achieved based on the discovery that the present invention has the following effects. (Structure of the present invention) That is, the present invention is a water-soluble cutting and grinding fluid characterized by containing an alkali metal salt or amine salt of a ricinoleic acid polycondensate (having an acid value of 40 to 145). In the water-soluble cutting and grinding fluid of the present invention, an alkali metal salt or amine salt of ricinoleic acid polycondensate (acid value of 40 to 145) may be used alone as is, and mineral oil or surfactant may be added to this. , an anticorrosive agent, a preservative, etc. may be added to form an emulsion type or soluble type by conventional means. At this time, ricinoleic acid polycondensate (acid value 40
The effective composition ratio of the alkali metal salt or amine salt (145 to 145) is difficult to uniformly determine in relation to other components used in combination, and is appropriately selected depending on the purpose of use, usage conditions, etc. In addition, ricinoleic acid polycondensate (acid value 40-145
Sodium or potassium is practically used as the alkali metal used in the alkali metal salt or amine salt of Among these, alkanolamines are particularly effective in the present invention. Ricinoleic acid polycondensate used in the present invention (acid value:
40 to 145) is obtained by dehydration condensation of ricinoleic acid by heating it to 150 to 240°C in a nitrogen stream according to a conventional method, but the degree of polycondensation of the polycondensate is defined using the acid value as an index. Bye. The appropriate value of the acid value of the ricinoleic acid polycondensate varies depending on the composition of the cutting and grinding fluid, and cannot be determined uniformly, but may be appropriately selected with reference to the following trends. That is, in general, the lower the acid value, the more advantageous it is in machinability and grindability, and if the acid value is 145 or more, the intended effects of the present invention cannot be obtained. On the other hand, if the acid value is too low, the emulsion will melt and the solubility of the solubles will deteriorate. Generally speaking, the preferred acid value of the ricinoleic acid polycondensate is 40-145. In addition, ricinoleic acid polycondensate (acid value 40-145
In the case of alkali metal salts or amine salts, as with ordinary cutting and grinding fluids, it is important to add alkali or amine in a slightly excess amount than the neutralization equivalent in order to improve the rust prevention and deterioration resistance of the diluted liquid. preferable. (Effects of the present invention) As mentioned above, the cutting and grinding fluid of the present invention contains an alkali metal salt or amine salt of a ricinoleic acid polycondensate (having an acid value of 40 to 145), and has excellent cutting and grinding properties. It has many effects such as being odorless, resistant to decay, resistant to deterioration, and has good antifoaming properties. (Examples) Next, the present invention will be described in more detail by describing Examples of the present invention, but the present invention is not limited to the following Examples. Examples 1 to 10, Comparative Examples A to D (1) Production of ricinoleic acid polycondensate Ricinoleic acid was heated to 200±10°C in a nitrogen stream,

From the results shown in Figure 1, the cutting and grinding fluid of the present invention has the same cutting properties as the cutting and grinding fluid containing a large amount of chlorine and sulfur (Comparative Example B), and the cutting and grinding fluid containing higher fatty acid salts (Comparative Example It is clear that the machinability is superior to C). Furthermore, among the compositions of the present invention, it can be said that ricinoleic acid polycondensates with a lower acid value, that is, those with a higher degree of polycondensation, are superior in machinability. FIG. 2 shows that the machinability improves as the concentration of P 50 in the diluent increases up to about 4 wt%. (b) Grindability Figures 3 and 4 show the results for the sample oils in Table 4. Figure 3 shows that at a sample oil concentration of 1wt%,
Figure 4 shows a comparison of the grinding resistance when the number of strokes was kept constant (500) and the concentration of the sample oil was varied. It is clear from the test results that the grinding fluid of the present invention is superior to conventional grinding fluids in terms of grindability. (c) Resistance to spoilage and sales Table 6 shows the results of measurements over time.
