とができなかった。[Detailed Description of the Invention] It is known to form a heat-resistant resin film such as fluororesin on the surface of cooking utensils for the purpose of imparting releasability and facilitating cleaning and removal of adhering cooking materials. . However, since stainless steel has poor adhesion with this type of resin and peels off during use of the cooking utensil, it has not been possible to form the resin film as described above.

We conducted research on a method for forming a resin film with excellent removability, and arrived at the present invention.

。In general, silicone-based paint resins are used to form films that require heat resistance on stainless steel cookware.
The main types are fluororesin and polyester, but polyether sulfone has the advantage of being hard, resistant to scratches, and easy to paint. However, it has poor heat-resistant adhesion and has not been put to practical use.As a result of numerous experiments aimed at improving this point, we have found that the stainless steel surface can be roughened to a certain range of surface roughness by blasting or helical processing. It was found that the problem could be solved by surface processing.

粗面加工する。In this case, the more complex the cross-sectional shape of the rough surface, the better the adhesion (,
It has been found that it is important that each of the maximum height Rmax, the 10-point average roughness Rz, and the center line average roughness Ra fall within a certain range. That is, Rmax is 90 to 30
Micron, Rz is 70-25 micron, Ra is 10-2
It is important that it is in the micron range. For this purpose, the surface to which the paint is to be applied is roughened by sandblasting or shotblasting, or by spiral finishing.

安全である。A stainless steel frying pan is treated with resin according to the present invention,
When a practical test was conducted, no abnormality was found in adhesion, hardness, stain resistance, etc. even after 3 months of use. Additionally, when water droplets are dropped onto a heated stainless steel plate that does not have a resin film, they scatter violently, but stainless steel plates coated with polyether sulfone paint containing fluororesin do not have this phenomenon and can be cooked easily. There is no danger of burns etc.
It's safe.
