Lubricating oils with a viscosity of are generally used, but when processing conditions become severe (e.g., increasing the processing speed and ironing rate in ironing, increasing the drawing height in deep drawing) Attempts have been made to use high-viscosity lubricating oils in order to improve processability. However, when a lubricating oil having a high viscosity is used, the degreasing property is reduced in the degreasing step of removing the lubricating oil after processing, and when performing painting or the like, there is a problem that unevenness in appearance occurs due to residual oil. there were. Regarding workability, even if a high-viscosity lubricating oil is used, the effect of improving workability is insufficient, and further improvement in workability has been expected.

る。Usually, metal soaps such as stearic acid and salts thereof are solid, and are commercially available as a lubricant dispersed in a surfactant or the like. When applied to the plate surface, lubricity is good, but metal soap is adsorbed on the aluminum plate surface, and degreasing with a common solvent or immersion in a weakly alkaline aqueous solution is sufficient. Cannot be completely degreased. However, by providing the above-mentioned water-soluble resin layer in advance, there is an effect of preventing the lubricant from directly adsorbing to the surface of the aluminum plate and improving the degreasing property.

るので好ましくない。However, the thickness of the water-soluble resin film layer must be in the range of 0.1 μm or more and 3 μm or less. 0.
If it is less than 1 μm, the surface is not sufficiently coated, and the lubricating film layer provided as the second layer partially adsorbs to the surface of the aluminum plate, and the degreasing property is reduced. Further, when the film thickness exceeds 3 μm, it takes time to elute and remove the resin of the first layer, and although the removability of the lubricating layer is good, the resin partially remains, and the steps after degreasing (for example, In the coating step), problems such as poor appearance occur, which is not preferable.

を主成分とした潤滑剤皮膜であれば良い。As described above, metal soaps such as stearic acid or calcium stearate, which is a salt thereof, are insoluble in water and are in a solid state. Therefore, those obtained by dispersing these as surfactants or resins as binders are commercially available. However, these can be used after being coated and dried as a lubricant film layer. In addition, it is of course possible to use the water-soluble resin used in the first layer as a binder in order to improve the film forming property of the lubricant film layer. In short, any lubricant film containing metal soap as a main component may be used.

好ましい。The thickness of the second lubricant film layer is not particularly limited, but is preferably 0.5 μm or more from the viewpoint of moldability and 2 μm or less from the viewpoint of preventing problems such as peeling.

さない利点がある。As a method of forming the first and second layers, an appropriate method can be used, and application by a bar coater or a roll coater is possible, but application by a brush or the like is also possible. Drying may be performed to the extent that both the first and second layers evaporate moisture (about 80 to 100 ° C.).
There is an advantage that long-time baking is not required and the material properties are not adversely affected.

The evaluation was made from 0 to 100%, where "100%" was when the film was completely removed by degreasing, and "0%" was when the film was not removed by degreasing. Furthermore, in order to clarify the residual resin or oil, an acrylic resin-based paint containing a blue dye of 1 μm is then baked.
The appearance was also evaluated.

In each case, the moldability is greatly improved as compared with the case where normal molding oil is used (No. 7), and the degreasing property is better than the case where high viscosity oil is used (No. 8), and the appearance is poor. Can not be seen. From these results, it is understood that the press oil and the lubricant film layer were completely removed by degreasing, and good degreasing properties were obtained.

The lubricant was partially adsorbed to the surface and the degreasing property was poor, and in the latter, the water-soluble resin remained even after immersion in water, and poor appearance was observed after painting.
