。However, as applications have diversified in recent years, the problem has arisen that these lubrication treatment methods may not be satisfactory when cold working conditions are severe. Furthermore, resin-based lubricants used after being diluted with organic solvents have had the problem of not being suitable for processing sites because the residual film cannot be easily removed with an alkaline cleaner after cold working.

As a result of intensive research aimed at developing a method, the method described above was developed, in which a lubricating film was formed by applying an aqueous solution containing polyethyleneimine and a thermoplastic water-soluble resin to the metal surface, and then lubricating oil was further applied on top of the lubricating film. The present invention was completed based on the discovery that it is a lubrication treatment method that can solve the following problems.

oo, but preferably 30.000 to 100.0
It is 00. If the molecular weight is less than 1,000, the toughness of the resin film decreases and the film breaks during processing, which is not preferable. If it is more than 100,000, there will be no change in lubricity, but the viscosity will become too high and workability will deteriorate, which is not preferable. Examples of the thermoplastic resin include polymers of acrylic esters, polyacrylamide, polyvinylpyrrolidone, polymers of ethyleneimine and other vinyl compounds, and saponified polymodified vinyl acetate. Other vinyl compounds copolymerized with ethyleneimine include, for example, vinyl acetate, styrene, methyl vinyl ether, acrylamide, vinyl bi-Olidone, and the like.

Depending on the cold working method, a solid lubricant may be added to the aqueous solution of polyethyleneimine and thermoplastic water-soluble resin. Examples of the solid lubricant include graphite, molybdenum disulfide, talc, Teflon, boron nitride, calcium carbonate, and melamine-isocyanuric acid adduct.

It is squeezed out, and this clogs the mold tool, which actually reduces workability! influence Therefore, preferably 0.5 to 15 g/m is appropriate for the dry film, but more preferably 0.5 to 15 g/m in the case of pressing, rolling, etc.
．． 5 to 39 g/m, and in the case of cold working such as wire rod, tube, and cold forging, it is 5 to 10 g/Td.

Barium salts of oil sulfonates may also be added. However, even if a lubricating oil is blended into the aqueous solution of polyethyleneimine and thermoplastic water-soluble resin in the present invention, it is not possible to obtain the performance that would fail to achieve the object of the present invention. The reason is,
This is because it reduces the adhesion of the film of polyethyleneimine and thermoplastic water-soluble resin to metal, and causes peeling and seizure during cold working.

焼付現象が起きない。In the practice of the present invention, in the initial stage of cold working, the film of polyethyleneimine and thermoplastic water-soluble resin cannot be peeled off even during ironing, and therefore the film remains on the surface of the processed metal, so that the metal and mold tool cannot be separated. contact can be prevented. In the deformation processing stage, the metal surface increases by 100 to 150 degrees Celsius due to metal deformation heat and frictional heat, improving the elongation of the resin film.
In order to follow the deformation of metal well and prevent film breakage,
No burn-in phenomenon occurs.

でそれだけ潤滑性が優っているという事ができる。As is clear from Table 3, the lubricating film formed on the surface of the steel plate by the lubrication treatment method of the present invention exhibited superior lubricating effects in the deep drawing test compared to the comparative example (commercially available lubricating oil). In particular, Examples 1 to 3 were all able to be squeezed out, and their lubricating effects were exhibited to the maximum. In Examples 4 to 7, it was not possible to draw out the material, so the drawing ratio values are shown, but since all of the values are higher than those in the comparative example, it can be said that the lubricity is that much better.

The removability of the lubricant film remaining on the surface of the four plates was excellent in all examples as it was completely removed, whereas in the comparative example the removability was extremely poor and the results were far inferior.

。As explained above, the metal surface lubrication treatment method according to the present invention first forms a dry film of 0.5 to 159/ci consisting of polyethyleneimine and a thermoplastic water-soluble resin on the metal surface, and then applies lubricating oil. Because it is a coating method,
It provides sufficient lubricity even during severe cold working conditions, and the residual film can be easily removed with an alkaline cleaner after cold working, making it suitable for workability at the processing site. It has a great effect.
