Definitions
- the present invention relates to a water-soluble metal working oil which can be used widely in various fields, being usable both for cutting and for grinding. More particularly, the present invention relates to a water-soluble metal working oil which can be suitably used in various metal working fields, for example, in the fields of cutting, grinding, forming, drawing, and rolling.
- the kind of metal working has determined the types of working oils to be used in each metal working; for instance, emulsion or soluble working oils have been used for cutting, and solution working oils for grinding.
- the reasons for using different working oils are as follows.
- conventional metal working oils for cutting and grinding have a problem that, as mentioned above, the oils for cutting and the oils for grinding need to be different, and therefore, there has been a demand for development of metal working oils which are usable both for cutting and for grinding.
- the conventional metal working oils have more problems. For example, even in case the conventional metal working oils for cutting are used for cutting, or the conventional metal working oils for grinding are used for grinding, their effects in improving working efficiency are insufficient, that is, in particular, the machined surfaces of the processed articles are not sufficiently accurate or the tool life tends to be decreased. Further, the conventional metal working oils still require improvement in anti-putrefaction property. Moreover, particularly in their use for grinding, there is another problem that it is difficult to extend the intervals between dressings sufficiently.
- An object of the present invention is to provide a water-soluble metal working oil which has excellent advantages in that when used for cutting, it can extend tool lives and improve the quality of the machined surfaces, and as well, when used even for grinding, it causes no loading of grindstones, thereby enabling dressing intervals to be extended, and therefore, it can also be used suitably as a working oil both for cutting and for grinding.
- Another object of the present invention is to provide a water-soluble metal working oil which hardly putrefies, thereby preventing coolants from putrefying more effectively.
- the object of the present invention is to provide a water-soluble metal working oil which is so extremely advantageous in practical use that it can be suitably used in various metal working fields.
- a water-soluble metal working oil which comprises a specific synthetic oil, i.e. an oligomer of an a -olefin having a specific number of carbon atoms or a hydrogenated derivative of the oligomer in place of or together with conventional mineral oils or synthetic oils.
- the present invention provides a water-soluble metal working oil, comprising: an oligomer component selected from the group consisting of oligomers of a -olefins of 6 to 14 carbon atoms and hydrogenation derivatives of the oligomers.
- the present invention further provides a water-soluble metal working oil, comprising:
- the present invention further provides a water-soluble metal working oil, comprising:
- the water-soluble metal working oil of the present invention comprises at least an oligomer component (component (A)) selected from the group consisting of oligomers of a -olefins of 6 to 14 carbon atoms and hydrogenation derivatives of the oligomers, and in addition to the component (A), it may further contain various kinds of additive components or diluents according to demand.
- component (A) selected from the group consisting of oligomers of a -olefins of 6 to 14 carbon atoms and hydrogenation derivatives of the oligomers, and in addition to the component (A), it may further contain various kinds of additive components or diluents according to demand.
- water-soluble metal working oil of the present invention In preparation of the water-soluble metal working oil of the present invention, there is no particular limitation in the order and method of adding each component.
- the water-soluble metal working oil of the present invention will be disclosed in detail as to its composition, etc.
- water-soluble metal working oils containing no diluent diiluting solvent such as water

- a proper emulsifier in addition to the above-described component (A). Any emulsifier, for example, any one selected from various known emulsifiers may be used in the present invention.
- anionic emulsifiers are preferably used, and it is particularly preferable to use the anionic emulsifiers (component (B)) together with nonionic emulsifiers (component (C)).
- oligomers of a -olefins of 6 to 14 carbon atoms to be used in the present invention include homopolymers (oligomers) of a -olefins of 6 to 14 carbon atoms, copolymers each consisting of two or more of the a -olefins, and mixtures thereof.
- the oligomer component (A) may further contain oligomers which contain monomer units of olefins other than the above-described a -olefins so long as the accomplishment of the object of the present invention is not disturbed.
- the a -olefins of 6 to 14 carbon atoms include aliphatic a -olefins, alicyclic a -olefins, and aromatic a - olefins.

- the suitable content of the anionic emulsifier to be used as the component (B) in the water-soluble metal working oil of the present invention is generally at least 5 % by weight, preferably from 25 to 80 % by weight, when the amount of the base liquid being defined above and comprising the component (B), the component (A), etc. (i.e., the total amount of all components excluding the diluents such as water) is defined to be 100 % by weight.
- the emulsion stability may become poor.
- the nonionic emulsifiers to be used as the component (C) in the present invention may be of various kinds.
