It is formed. Since the pigment (41) having a photocatalytic function is present in the uppermost layer (4), the catalytic activity is increased by irradiation of ultraviolet rays, oxidation is promoted, and the surface of the uppermost layer (4) is made hydrophilic. As a result, when water flows or the water flows, the surface of the uppermost layer (4) is washed, and dirt on the surface is washed away.

の変褪色がより確実に防止される。On the other hand, as described above, there is a problem that the decorative layer (3) formed on the inorganic coated plate is deteriorated by such an oxidizing action of the substance having a photocatalytic function. In the painted board, since the decorative layer (3) has an inorganic coating at least on the uppermost part, the inorganic coating prevents the invasion of the oxidizing action and realizes the oxidation and hydrophilicity of only the surface layer. . This inorganic coating is also strong and reliably protects the decorative layer (3). Even when the colored layer (31) of the decorative layer (3) is formed from an organic paint, the deterioration is sufficiently suppressed. In order to more reliably protect the decorative layer (3), it is effective to include an ultraviolet absorber in at least the uppermost inorganic coating film. The UV absorber prevents ultraviolet rays from entering the interior of the decorative layer (3), and the colored layer (31) of the decorative layer (3).
Is more reliably prevented.

Further, the inorganic coated plate of the invention of the present application can prevent the decorative layer (3) from deteriorating and can maintain a beautiful state.

はないからである。Incidentally, the inorganic coating plate is mainly used as an exterior material of a building. When the inorganic coated plate of the invention of this application is used as such an exterior material, the uppermost layer (4) on its surface is oxidized by ultraviolet rays existing under a general environment and becomes hydrophilic. However, if early hydrophilization is desired, in the inorganic coated plate of the invention of this application, the uppermost layer (4) can be irradiated with ultraviolet rays in the final step of the production to be activated in advance.
This pre-activation treatment is absolutely necessary for an inorganic coated plate used as an interior material. because,
This is because when used as an interior material, the uppermost layer (4) is not exposed to ultraviolet rays as much as when it is constructed outdoors as an exterior material.

It is manufactured as follows. That is, in the method for producing an inorganic coated plate of the invention of this application, after forming a decorative layer (3) having an inorganic coating film at least on the uppermost portion via a waterproof sealer layer (2) on the surface of an inorganic substrate (1). Then, a dispersion containing a pigment (41) having a photocatalytic function is applied and baked on the decorative layer (3) to form an uppermost layer (4).

It is possible to use one containing one or more photocatalysts such as O 3 , FeTiO 3 , SrTiO 3, etc., or one that itself becomes a pigment.

As the inorganic coating, for example, an inorganic coating applicable to the inorganic coating film of the decorative layer (3) can be similarly applied. There is no particular limitation on the type of the solvent.

決めることができる。In the dispersion, the mixing ratio of the pigment (41) is generally 10 to 20 parts by weight. Therefore, the mixing ratio of the inorganic paint can be determined with respect to the pigment (41).
【００２２】以下の表１は分散体の試験例である。Table 1 below is a test example of the dispersion.

無機塗料はバインダーとしても機能するのである。As can be seen from Table 1, when the amount of the pigment (41) is 10 to 20 parts by weight, and when the amount of the inorganic coating is less than 5 parts by weight, the dispersibility of the pigment (41) is considerably deteriorated, and It becomes difficult to obtain a proper dispersion. In this case, the performance of the formed uppermost layer (4) is reduced. On the other hand, when the amount of the inorganic paint exceeds 30 parts by weight, the hydrophilicity of the uppermost layer (4) decreases. This is probably because the pigment (41) is buried and fixed in the inorganic paint, and the oxidizing action is not promoted. Thus, the inorganic paint contributes to the dispersibility of the pigment (41). Further, by using the inorganic paint, the uppermost layer (4) is well bonded to the inorganic coating film of the decorative layer (3) formed immediately below. That is, the inorganic coating compounded in the dispersion also functions as a binder.

The dispersibility of 1) can be improved by a dispersant. The effect is 1 to 10 to 20 parts by weight of pigment (41).
A mixing ratio of 5 parts by weight is sufficient. There is no particular limitation on the dispersant that can be used, and any suitable dispersant including conventionally known dispersants can be used. The dispersant is also applicable when using an inorganic paint, and shortens the dispersion time.

When such a fine particle dispersion is used, the compounding ratio of the pigment (41) is converted into the solid content of the fine particle dispersion, and the compounding ratio of the solvent is defined as the compounding amount of the solvent contained in the fine particle dispersion. It is necessary to consider.

The top layer (4) can be formed by painting and baking the decorative layer (3). Specifically, the baking of the dispersion is preferably performed when the decorative layer (3) is in a dry state to the touch.

散体の塗装焼付の試験例である。The baking time of the dispersion also affects the hydrophilicity of the uppermost layer (4) to be formed. Table 2 below is a test example of paint baking of the dispersion.

【表２】 [Table 2]
【００３０】この表２から明らかなように、化粧層

（３）が湿潤状態にある時に塗装焼付すると、親水度は
さほどとはならない。これは、分散体中の顔料（４１）

促進されないためと考えられる。As is clear from Table 2, when the dispersion is painted and baked when the decorative layer (3) is in a dry-to-touch state, the hydrophilicity of the uppermost layer (4) is sufficiently high. On the other hand, if the paint is baked when the decorative layer (3) is in a wet state, the hydrophilicity is not so high. This is because the pigment (41) in the dispersion
Is likely to sink into the wet decorative layer (3), and the oxidizing action is not promoted.
【００３１】なお、分散体の塗装方法については特に制

ても特に制限はない。The method for coating the dispersion is not particularly limited, and various methods such as spraying, roll coating, and flow coating can be appropriately employed. There is no particular limitation on the printing method.
