いえない。Conventionally, stainless steel itself has a good corrosion resistance and a good design appearance. On the other hand, since the adhesion of the coating film to the stainless steel is not good, the stainless steel surface is hardly coated. However, with the expansion of the field of use of stainless steel, it has recently been required to apply a coating film for the purpose of further improving the corrosion resistance, improving the design appearance, and other functions. In response to these demands, the application of a fluorine resin coating film has attracted particular attention as a coating for stainless steel. For example, it is being studied to be used as an outer wall material for buildings due to the high weather resistance and stain resistance of the fluororesin coating film, and as a roof material for snowy areas because of its low friction coefficient. However, since the metal surface of stainless steel is chemically extremely stable, the adhesion of the coating film is poor, and particularly the adhesion of the fluororesin coating film is poor. As a method for improving the coating film adhesion to the metal surface of stainless steel, a method of physically roughening the metal surface such as shot blasting and hairline processing is performed, but this is not enough for the coating film adhesion. Absent. A chromate-based coating is also known as a coating base agent, but it is not a preferable treatment method in view of the problem of work hygiene due to the toxicity of chromate.

以外の汎用塗料の場合に適用することも可能である。The stainless steel to which the present invention is applied is not particularly limited to the steel type, and can be applied to various martensitic, ferritic, and austenitic stainless steels containing about 10% by weight or more of chromium. The silane coupling agent having an amino group used in the present invention, H 2 NC 2 H 4 NHC 3 H 6 Si (OCH 3 ) 3 H 2 NC 2 H 4 NHC 3 H 6 Si (CH 3 ) (OCH 3 ) 2 H 2 NC 3 H 6 Si (OC 2 H 5 ) 3 or the like can be used. Other silane coupling agents such as vinyl silane, methacrylosilane, epoxy silane, etc. also contribute to improving the adhesion of the coating film, but silane coupling having an amino group is used to improve the adhesion of the fluorine resin coating film to stainless steel. The agent is optimal. The silane coupling agent having an amino group can be applied by dipping, spraying, electrostatically, rolling, brushing or the like.
The coating amount of the silane coupling agent having an amino group is 1 to 5
200 mg / m 2 preferably from 3 to 50 mg / m 2. 1 mg /
If it is m 2 or less and 500 mg / m 2 or more, the effect of adhesion of the coating film cannot be sufficiently exhibited. If it is 500 mg / m 2 or more, the adhesion of the coating film may be rather decreased. 1-5
In order to apply a coating amount of 00 mg / m 2 uniformly, it is diluted with a solvent and applied, but the degree of dilution is 1 to 5 g / m 2 or more as a solvent diluting solution, and then dried. It is sufficient to form a predetermined amount of uniform film.
The coating solution containing the silane coupling agent having an amino group may be dried as long as the solvent is removed, and may be naturally dried depending on the kind of the solvent, but it is usually 10 to 80 ° C at 200 to 200 ° C.
It is advantageous in terms of work to keep for 2 seconds to 3 minutes. The metal surface of the stainless steel to which the silane coupling agent having an amino group is applied needs to be clean and degreased beforehand. The fluororesin coating film applied to the present invention may be a commercially available coating material suitable for various purposes and is not particularly limited. It can also be applied to the case of sticking a fluororesin coating in the form of a pre-formed film. The silane coupling agent having an amino group can also be applied to general-purpose paints other than fluororesin paints.

The solution was applied on the surface of about 1.5 g / m 2 and dried in a hot air circulation oven at 130 ° C. for 3 minutes, and about 15 mg / m 2 of γ-aminopropyltriethoxysilane was uniformly applied on the metal surface of stainless steel. After that, coating was performed using the commercially available fluororesin paints shown in A to E of Table 1. Commercially available fluororesin paints A to E are resins having trade names (including registered trademark) Duraner, Fluoropon, Dufner, V Freon, and Neugermet (the above are not in the corresponding order with A to E). The fluororesin paint was applied by the bar coat method, and the film forming conditions were standard conditions according to the specifications of each paint.

The adhesion after boiling water is the boiling of the coated plate. The adhesion test was carried out immediately after immersion in deionized water for 1 hour, and the adhesion after immersion in warm water means the adhesion test immediately after immersion in deionized water at 40 ° C. for 20 days. Moreover, in Table 1, the cross-cut is 100 cross-cuts of 1 mm square on the coated plate, and after scratching until reaching the base with a cutter knife, the cellophane tape is attached to the coated surface and then peeled off. It is the adhesion of the coating film expressed by (the number of remaining coating grids) / (100 pieces), and the cross-grid Erichsen is the same method as the cross-grid.

In the same manner as in 5, apply about 0.5 mg / m 2 of γ-aminopropyltriethoxysilane so that it is evenly applied to the stainless steel surface, and keep the other conditions the same as 4 in Table 1, After forming the fluororesin coating film D on the surface of the steel, an adhesion test was conducted. The coating adhesion in this case is almost at the same level as in Table 1, and therefore a coating amount of γ-aminopropyltriethoxysilane of 1 mg / m 2 or less has a small effect of improving the coating adhesion.

The coating amount of γ-aminopropyltriethoxysilane was 500 mg / m 2 If it exceeds, the result shows that the performance is slightly lower than that, and the effect of improving the coating film adhesion is small.

実施することができる。 [Effect] As described above, when a fluororesin coating film is formed on the metal surface of stainless steel, by using an appropriate amount of a silane coupling agent having an amino group, the adhesion strength of the coating film can be significantly increased. , Thereby producing a coated stainless steel sheet in which the excellent weather resistance, antifouling property, and slippery coating film of the fluororesin coating film are formed with strong adhesion, while hardly changing the surface appearance of the stainless steel. Things are possible. In the examples, examples of stainless steel with hairline finish were shown, but the present invention is not limited to hairline finish, and it is possible to greatly improve coating adhesion even with brightly annealed finish stainless steel, Therefore, it is possible to manufacture colored coated stainless steel having excellent luster, which is extremely useful for expanding the range of designs to which stainless steel is applied. In addition, according to the method of the present invention, the work of roughening the surface of stainless steel by polishing or shot blasting, which has been conventionally performed to enhance the coating adhesion, can be reduced or omitted, and thus the outer wall of a building or a roofing material, etc. The manufacturing process can be streamlined. Since the method of the present invention does not use chromate or the like, it does not require special consideration in work hygiene and can be easily carried out.
