０５〜５．０μｍの範囲が好ましい。[0006] Particulate fillers are added to prevent bubbling and pinhole-like defects after baking. In the baking step, the coating film is dried from the surface side, but in the case of a coating film using water as a solvent, water vapor tends to remain inside the coating film. This residual water vapor becomes bubbles, which causes foaming and pinhole-like defects. When the particulate filler is dispersed and mixed in the coating film, the water vapor remaining inside the coating film is easily radiated to the outside of the coating film along the filler particles, so that foaming and pinhole-like defects can be prevented. . The particulate filler that can be used in the present invention is not particularly limited as long as it is insoluble in an aqueous alkali silicate glass solution at room temperature, does not change its form such as melting or incineration at the baking temperature after coating, and can maintain its particle state. For example, colloidal alumina, glass powder particles, oxides containing metals (such as titanium oxide), boride substances, and the like can be used. These particulate fillers can be used alone or as a mixture of two or more kinds, and the average particle size of the particulate filler is 0.1.
The range of from 0.05 to 5.0 μm is preferred.

低下する。If the average particle size of the particulate filler is less than 0.05 μm, the effect of adding the particles is not recognized. If it exceeds 5.0 μm, secondary aggregates are easily formed. Workability and transferability to a metal plate during roll coating are deteriorated. The compounding amount of the particulate filler is 10 to 6 with respect to 100 parts by weight of the solid content of the aqueous alkali silicate glass solution.
0 parts by weight, preferably in the range of 20 to 50 parts by weight.
If the amount is less than 10 parts by weight, the effect of preventing foaming and pinhole-like defects is poor. If the amount is more than 60 parts by weight, the dispersibility of the coating material is deteriorated and the coating workability is affected. In addition, the amount of alkali silicate glass forming the composite film is insufficient, and the film strength and durability are reduced.

The ratio is 60 parts by weight. When the amount is less than 10 parts by weight, no improvement in non-adhesiveness is not recognized. When the amount is more than 70 parts by weight, the dispersibility of the coating material deteriorates and the coating becomes difficult. In addition, the hardness and heat resistance of the coating film decrease.

などを使用することができる。The composite coating prepared as described above is applied to a metal plate by a known method such as spraying, roll coating, and gravure coating so that the dry film thickness becomes 7 to 20 μm.
When the dry film thickness of the composite coating film is less than 7 μm, there is no concealing property, and the non-adhesiveness is inferior because a layer such as PTFE is not sufficiently formed. If the coating thickness exceeds 20 μm, not only is it difficult to apply a single coat, but also the adhesion and processability are reduced. In the present invention, the production can be performed by one coating, so that the cost can be reduced. The baking temperature after application is a temperature higher than the melting point of the tetrafluorinated fluororesin. For example, the melting point of PTFE is 327 ° C.
Since the melting points of other tetrafluoride-based fluororesins are similar, baking is performed at an ambient temperature of 350 to 400 ° C.
Color pigments are also added to the composite paint, but pigments that do not change color even at high temperatures, for example, a Cu—Fe—Mn-based composite oxide pigment can be used.

It was as high as -128 degrees, had water repellency, and showed good non-adhesiveness. Further, it was found that the coating film hardness was as high as 7H to 8H in pencil hardness, the heat resistance and the adhesion were good, and the coating film properties were excellent. On the other hand, in Comparative Example 1 in which PTFE was not blended and Comparative Example 2 in which the blending amount of PTFE was small, the pencil hardness, heat resistance and adhesion were good, but the non-adhesiveness was inferior. Conversely, Comparative Example 5 in which PTFE was excessively blended

Further, even when the amount of PTFE is within the range of the present invention, the non-adhesiveness is inferior in Comparative Example 3 in which the dry coating thickness is as thin as 5 μm, and conversely, in the Comparative Example 4 in which the dry coating thickness is as thick as 30 μm Sex was slightly inferior. The commercially available organic non-adhesive coated steel sheet (Comparative Example 10) has a pencil hardness of F in particular.

In Comparative Examples 6 and 8, in which no particulate filler was blended, poor appearance due to foaming or pinhole defects occurred after baking, and the blending amount of the particulate filler was within the range of the present invention. Even in Comparative Examples 7 and 9 having a large average particle diameter of 8 μm, coating was impossible due to aggregation of the composite coating.
