４）。2. Description of the Related Art In the field of construction and paints, contamination of architectural exterior materials, outdoor buildings and coating films thereof has become a problem due to environmental pollution. Dust and particles suspended in the air accumulate on the roof and outer walls of buildings in fine weather. Sediment is washed away by rainwater as it rains and flows down the building's outer walls. Furthermore, in the rain, the floating dust is carried by the rain and flows down on the outer wall of the building or the surface of the outdoor building. As a result, pollutants adhere to the surface along the path of rainwater. When the surface dries, striped stains appear on the surface. Dirt on building exterior materials and coatings consists of combustion products such as carbon black, and inorganic pollutants such as urban dust and clay particles. It is thought that such a variety of contaminants complicates antifouling measures (Yoshinori Tachibana, "Method for Accelerated Testing of Contamination of Exterior Wall Finishing Materials", Proc. No., October 1989, p.15-2
4).

Although water-repellent paints such as FE) were considered preferable, recently it has been considered that it is desirable to make the surface of the paint film as hydrophilic as possible for urban dust containing a large amount of hydrophobic components. (Polymer, Vol. 44, May 1995, p. 307). Therefore, it has been proposed to paint a building with a hydrophilic graft polymer (newspaper "Chemical Industry Daily", January 30, 1995). According to reports, this coating exhibits a hydrophilicity of 30 to 40 ° in contact angle with water. However, the contact angle of inorganic dust represented by clay minerals with water is from 20 ° to 50 °, and has an affinity for the graft polymer having a contact angle with water of 30 to 40 ° and adheres to the surface. Therefore, it is considered that this graft polymer coating film cannot prevent contamination by inorganic dust.

Although there are proposals that can be made, the effect was not sufficient because the surface could not be maintained at a high degree of hydrophilicity for a long time. In view of the above circumstances, an object of the present invention is to provide a member capable of maintaining a surface with a high degree of hydrophilicity for a long period of time.

る。According to the present invention, a surface layer containing photocatalytic titanium oxide particles having an average crystallite diameter of less than 800 nm, more preferably an average crystallite diameter of 300 nm or less is formed on the surface of a substrate. And a photocatalytic hydrophilic tile, wherein the surface layer exhibits hydrophilicity in response to photoexcitation of the photocatalytic titanium oxide. By doing so, when the photocatalytic titanium oxide particles are photoexcited, the surface of the tile becomes hydrophilic. This phenomenon is considered to proceed by the following mechanism. That is, when light having energy equal to or more than the energy gap between the upper end of the valence band of the photocatalyst and the lower end of the conduction electron band is irradiated on the photocatalytic oxide, the electrons in the valence band of the photocatalyst are excited to become conductive electrons and positive electrons. Pores are created, and either or both actions may possibly impart polarity to the surface, collecting polar components such as water and hydroxyl groups. Then, one or both of the conduction electrons and holes and the above-mentioned polar components cooperate to cut the chemical bond between the adsorption surface and the contaminant chemically adsorbed on the surface, and the chemically adsorbed water on the surface. It adsorbs and a physisorbed water layer is formed on it.

An oxide that can generate conduction electrons and holes by the excitation of electrons (photoexcitation) in the band. Anatase-type titanium oxide, rutile-type titanium oxide, tin oxide, zinc oxide, bismuth trioxide, tungsten trioxide, Ferric oxide, strontium titanate and the like can be suitably used. Here, as a light source used for photoexcitation of the photocatalytic oxide, indoor lighting such as a fluorescent lamp, an incandescent lamp, a metal halide lamp, and a mercury lamp, the sun, and a light source in which light from those light sources is guided by a low-loss fiber are used. It can be suitably used. In order for the substrate surface to be highly hydrophilized by photoexcitation of the photocatalytic oxide, the illuminance of the excitation light is 0.001 m

物質の分解を促進する。The thickness of the surface layer is preferably 200 nm or less, especially when the substrate is transparent. Then, it is possible to prevent the surface layer from being colored by light interference. Also, the thinner the surface layer, the more transparent the member can be. Further, when the film thickness is reduced, the wear resistance of the surface layer is improved. The surface of the surface layer may be further provided with a wear-resistant or corrosion-resistant protective layer capable of being made hydrophilic and other functional films. Preferably, the surface layer does not have a very high refractive index as compared to the substrate. Preferably, the refractive index of the surface layer is 2 or less. Then, light reflection at the interface between the base material and the surface layer can be suppressed. When the substrate is a glass or glazed tile containing an alkali network modifying ion such as sodium, an intermediate layer such as silica may be formed between the substrate and the surface layer. Then, the diffusion of the alkali network modifying ions from the base material to the surface layer during the firing is prevented, and the photocatalytic function is more effectively exhibited. Metals such as Ag, Cu, and Zn can be added to the surface layer. The surface layer to which the metal is added can kill bacteria adhering to the surface. Furthermore, this surface layer
Inhibits the growth of microorganisms such as mold, algae and moss. Therefore,
Adhesion of dirt on the member surface due to microorganisms is more effectively suppressed. Pt, Pd, Rh, R
A platinum group metal such as u, Os, Ir can be added. The surface layer to which the metal is added can enhance the oxidizing activity of the photocatalyst, and promote the decomposition of contaminants attached to the member surface.

As shown in FIG. After the obtained sample was left in a dark place for one week, a black light blue (BLB) lamp of Sankyo Electric Co., Ltd. was irradiated with an ultraviolet illuminance of 0.3 m.
Irradiation was carried out at W / cm 2 , and the change in contact angle with water with respect to the irradiation time was measured. The measurement of the contact angle with water was determined by a contact angle measuring device (Kyowa Interface Science, CA-X150) at a value 30 seconds after a water droplet was dropped from a micro syringe. For comparison, a normal glazed tile was similarly irradiated with a BLB lamp having an ultraviolet illuminance of 0.3 mW / cm 2 , and the change in the contact angle with water with respect to the irradiation time was measured.

が好ましいといえる。Table 1 shows the average crystallite diameter of anatase type titanium oxide (A-6) in the sample fired at 110 to 900 ° C. Here, the average crystallite diameter was calculated by obtaining the integral width of the strongest peak of anatase-type titanium oxide by powder X-ray diffraction method and substituting the obtained value into the Scherrer equation. As a result, at 900 ° C., the average crystallite diameter was 800 nm.
It is thought that this weakened the hydrophilicity restoring power. Therefore, it can be said that the average crystallite diameter of titanium oxide constituting the member after firing is preferably less than 800 nm.

At 900 ° C., it was found that good hydrophilicity restoring property was exhibited even though the average crystallite diameter had grown to about 300 nm. Therefore, if the average crystallite diameter of the titanium oxide constituting the fired member is at least 300 nm or less, it can be said that good hydrophilicity recovery properties are exhibited.
