Abstract

<P>PROBLEM TO BE SOLVED: To provide a fluororesin-coated frying pan capable of preventing release of silk printing on the surface of the fluororesin coating and improving the mold releasing property and abrasive resistance of the fluororesin coating. <P>SOLUTION: The three-layer fluororesin-coated frying pan has an improved design with silk screen printing and pat printing with a special ink d between a fluororesin intermediate coating layer c and a top coating layer e, and the surface of the flying pan is smoothed by embedding the special ink d in the intermediate coating layer c with high-pressure pressing. The mold releasing property and the abrasive resistance, which are characteristics of fluororesin, are strengthened. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to printing on the inner surface fluororesin of a frying pan main body, and fluororesin reinforcement.

  Conventional inner surface fluororesins of a frying pan body are non-adhesive in nature.

However, according to the conventional technique, when silk printing is applied to the surface of the fluororesin, the abrasion resistance is remarkably deteriorated, and the silk printing is immediately peeled off in normal use.

  In the present invention, first, special ink is applied between a fluororesin intermediate coat and a topcoat of a three-layer fluororesin coat frying pan by silk screen printing and pad printing, and the surface of the fluororesin is colored and designed. Secondly, by embedding special ink together with the first in the intermediate coat, it is possible to smooth the plane, and to greatly improve the releasability and strengthen the wear resistance which are the characteristics of fluororesin. To do.

  In the present invention, the surface of the fluororesin is designed and the releasability is greatly improved by utilizing the characteristics of the conventional fluororesin by the following production method.

1. Sand is applied to the aluminum circle plate to roughen the surface.
2. Apply primer coat to the surface.
3. Firing for about 15 minutes at a furnace temperature of 120 to 150 degrees.
4. Spray an intermediate coat on the surface.
5. Baking for about 15 minutes at a furnace temperature of 120 to 150 degrees.
6. Special silk screen on the surface.
7. Bake for 15 minutes at 150 ° C furnace temperature
8. Press work.
9. Spray top coat.
10. Firing for 15 minutes at a furnace temperature of 380 to 410 degrees.
11. Apply pressure to the fluororesin surface again with a 1000 ton press.

  By putting silk screen printing between the middle coat and top coat of the three-layer fluororesin, and applying pressure after top coating with a 1000 ton press, the surface of the fluororesin has no projections and becomes smooth, Furthermore, when pressure is applied by pressing, the surface of the fluororesin is tightened and the characteristics are greatly improved.

  In FIG. 1a in the above process chart, b fluorine resin undercoat c intermediate coating is performed. Fig. 2c The design is formed by applying d special ink on the surface of the intermediate coat. Apply e-top coat on top of the surface from Figure 3d. FIG. 4 Press with a high-pressure press, d ink is embedded in the c intermediate coat, and the surface is smoothed.
