る。The metal plate on which the above-mentioned adhesive film is laminated can be finished to a predetermined shape by a molding process. However, depending on the characteristics of the metal plate, the formability can be improved by applying a press oil. (Scratch resistance) in some cases. When applying the press oil, sufficient attention must be paid to the application of the press oil because the adhesive force is reduced when the press oil adheres to the surface of the adhesive. If the press oil adheres to the adhesive surface by mistake, a problem arises as a reduction in the yield of the material. Therefore,
Although it is conceivable to add a step of cleaning the adhered press oil, equipment for this is required, which increases the cost.

From 10 to 100% of the melting peak of differential scanning calorimetry of the material cured by cooling to room temperature is preferably used.
If it is less than 10%, normal non-adhesiveness cannot be obtained. If the molecular weight is less than 5,000, the moldability is poor, and if the molecular weight exceeds 80,000, the blocking resistance decreases. Therefore, it is desirable to use nylon having a molecular weight of 5,000 to 80,000.

Therefore, it is desired that the adhesive surface and the lubricating surface do not adhere in a temperature range from −10 ° C. to the melting point of the resin or under a pressure of 50 kg / cm 2 . For this reason, it is necessary to appropriately select the type of resin and the baking temperature range according to the use conditions so that the adhesive surface of the product does not stick.

It is an ester type urethane resin, and the weight ratio of the polyether skeleton to the polyester skeleton is 10:90 to 7
0:30 is desirable. If the ratio of the polyester is higher than this range, the lubricity is adversely affected, and if the ratio of the polyether is high, the elongation is deteriorated although it is tough.
The amount of the carboxyl group is suitably from 10 to 50 in terms of acid value per urethane solid. If less than 10,
Poor adhesion and poor workability and corrosion resistance. If it exceeds 50, the corrosion resistance is reduced due to poor water resistance and alkali resistance.

It is desirable to mix at a ratio that reacts with 0 to 100%.
If it is less than 20%, the compounding effect is poor, and if it exceeds 100%, the epoxy resin plays a role of a plasticizer, so that a high degree of processability is reduced.

性を低下させるので高度の加工性は得られない。The melting point of the polyolefin wax is preferably from 70 to 160 ° C., because the film temperature rises due to the heat of deformation and frictional heat of the material during metal plate processing. If the temperature is lower than 70 ° C., the material softens and melts during processing, and excellent characteristics as a solid lubricating additive cannot be exhibited. On the other hand, if the melting point exceeds 160 ° C., hard particles are present on the surface and the frictional characteristics are reduced, so that high workability cannot be obtained.

Those having a saponification value of more than 30 have a large polarity and are easily compatible with the resin, so that they are less likely to be present on the resin surface during film formation. Therefore, it is not appropriate when a high processing performance level is required.

High workability and corrosion resistance cannot be obtained. If the addition amount is less than 10%, the effect is insufficient, and if it exceeds 40%, the binder effect of the resin is reduced, the corrosion resistance is reduced, and the elongation and strength of the resin are reduced.

The baking temperature is appropriately selected for the adhesive organic substance within a range that conforms to the above-described DSC melting peak intensity condition.
About 300 ° C. If the baking temperature of the lubricating organic material is less than 80 ° C, the resin reflow and cross-linking reaction will be insufficient, resulting in a film with a rough surface and many defects, and if it exceeds 200 ° C, the resin and lubricant will undergo thermal decomposition and thermal oxidation, resulting in performance. 80 to 200 ° C. is desirable.

覆鋼板について、以下に示す性能試験を行った。As shown in Table 1, as an adhesive organic substance, a nylon-based resin (crystallinity: DSC melting peak strength) was 90% of the DSC peak strength of the nylon-based resin cured by cooling from 170 ° C. to room temperature. The molecular weight was about 50.
000) resin and a polyolefin-based (non-crystalline, molecular weight of about 50,000) resin, and as a lubricating organic material, an ether ester urethane resin having a molecular weight of 5,000 (bisphenol A ether: oxidation 8, ether / ester ratio 30/70, The sum total of isocyanate content 8) and propylene glycol epoxy resin (epoxy equivalent 220) was 66% by weight based on the total solid content, 21% by weight of silica sol having an average of 8 nm, and polyethylene wax having a particle diameter of 0.6 to 20 μm (specific gravity 0). .93, softening point of 120 ° C.) was prepared in 13% by weight. Next, an adhesive organic substance was applied to the front of the hot-dip galvanized steel sheet that had been subjected to the coating type chromate treatment, and a lubricating organic substance was applied to the back side with a bar coater, and baked at the baking temperature shown in Table 1 and immediately cooled with water. Then, the steel sheet of the present invention example shown in Table 1 was manufactured. In addition, as a comparative example, a hot-dip galvanized steel sheet in which only the adhesive organic substance was applied to the front surface was manufactured. The obtained organic coated steel sheet was subjected to the following performance tests.

ンを図り得る。The organic coated metal plate of the present invention can be press-formed without using a press oil which adversely affects the adhesive, so that the user of the metal plate can not only omit the press oil application step but also mistakenly As a result, there is no need to worry about a decrease in the yield due to the adhesion of the press oil to the adhesive surface. Also,
There is no need to wash the press oil. That is, by using the organic-coated metal plate of the present invention, the user of the metal plate can complete the bonding by omitting all of the adhesive application step, the press oil application step, and the cleaning step. Further, the bonding can be performed in a short time of about several seconds, and the cost can be reduced in fields such as building materials, home appliances, sundries, and automobiles.
