Description of the Related Art Since a stainless steel plate is hard, when it is processed into a building material such as a shutter slat or a spandrel by roll forming or the like, galling occurs at a portion where a forming roll is hit. In particular, this galling is caused by the shutter
In the case of slats, processing is severe, and the surface of a stainless steel plate is beautiful, so that it stands out and significantly impairs the appearance. In addition, if the above-mentioned molded article is handled with bare hands at the time of construction, fingerprints adhere and become very conspicuous, and when used outdoors, rust is easily generated by chlorine ions.

This is a transparent vinylidene fluoride resin paint with excellent durability. However, since the vinylidene fluoride resin coating film is soft, the coating film is easily scratched at the time of molding processing, at the time of handling or transporting the molded product, and impairs the appearance and corrosion resistance. As a countermeasure, it has been attempted to improve lubricity by adding modified polyethylene particles to the coating film, but the abrasion resistance, scratch resistance is not sufficient, and the coating film adhesion is unstable. there were.

Although it is provided to ensure corrosion resistance, in the case of the present invention, since the vinylidene fluoride resin coating is transparent, if the chromate coating is colored, it appears in the appearance.
Therefore, in the present invention, the total Cr content of the chromate film is set to 40%.
mg / m 2 or less so as not to impair the appearance. However, if the total Cr content is reduced, the adhesion of the coating film and the corrosion resistance decrease, so the total Cr content was set to 5 mg / m 2 or more.

) Is excellent in slipperiness (low friction), so when the powder is added to a transparent vinylidene fluoride resin coating film, it acts as a lubricant to improve the wear resistance and scratch resistance of the coating film. Improve. Further, since it is a resin of the same type as the vinylidene fluoride resin, the adhesion to the coating film is good, and the addition does not impair the adhesion of the coating film. In addition, the transparent vinylidene fluoride resin coating film to which PTFE powder is added may not be completely transparent, and may be translucent enough to show the base of a stainless steel plate.

When the particle size is larger than 20 μm, the unevenness of the coating film becomes large and the appearance is deteriorated. And the particle size is 3 to 20 μm. If the amount is less than 1% by weight, the abrasion resistance and scratch resistance are inferior, and if it exceeds 20% by weight, the coating film adhesion and processability are reduced. .

When the amount of E powder added is increased, the gloss of the coating film is reduced and the glittering feeling peculiar to the stainless steel plate is impaired.

ましい。The thickness of the transparent vinylidene fluoride resin coating film is determined depending on the application, but if it is less than 3 μm, the abrasion resistance and corrosion resistance are reduced. However, vinylidene fluoride resin is expensive, and if the coating film is made thicker, the coating cost becomes higher. Therefore, the thickness is preferably 25 μm or less.

リン酸亜鉛処理液で十分である。In the production of the transparent fluororesin-coated stainless steel sheet of the present invention, the stainless steel sheet is generally subjected to a degreasing treatment and a phosphate treatment sequentially, followed by a chromate treatment, and then to a P steel treatment.
This is performed by applying a transparent vinylidene fluoride resin paint containing TFE powder. When a phosphate treatment is performed before the chromate treatment, in the case of a stainless steel plate, the wettability to the chromate treatment liquid is inferior, and a uniform chromate film cannot be formed only by the degreasing treatment. Because. For this phosphating treatment, the zinc phosphate treatment liquid used for the pre-coating treatment is sufficient.

It is preferable to use one containing silica as disclosed in No. 6057. This treatment solution is roll coated on a stainless steel plate.
It is preferable to apply by a tar, curtain flow coater or dipping and pulling, squeeze with a roll or the like, and then dry at 80 to 200 ° C. without washing with water.

Although it is advisable to use a known method such as a drying method, it is necessary that the drying be higher than the melting point of the vinylidene fluoride resin and lower than the melting point of the PTFE resin so that the PTFE powder remains in the coating film even after the drying. Therefore, it is performed at 240 to 270 ° C.
