ストが嵩むという問題があった。2. Description of the Related Art Recently, attention has been paid to the photocatalytic function of titanium oxide, and the photocatalytic function of titanium oxide is used to decompose organic substances such as dirt and germs in the air and NOx to purify the air. Has been attempted in various fields. For example, in a pavement block mainly composed of cement, titanium oxide is blended in cement mortar constituting the pavement block. However,
In the pavement block, dust and sand easily adhere to the surface,
In addition, since sunlight is blocked by people and buildings, there is a problem that titanium oxide in the pavement block cannot exert its photocatalytic function sufficiently. Further, it is known to apply a paint containing titanium oxide to the surface of a cement-based wall material constituting an outer wall of a building. However, in this case, there is a problem that the process becomes complicated and the cost increases.

Cement tiles and slate are common, and the roofing material of the present invention may be any of them. The titanium oxide powder may be uniformly contained in the cement-based kneaded material constituting the roofing material, or may be contained only in the kneaded material constituting the surface layer. If you want to include it in the whole,
When the manufacturing process is simplified and only the surface layer is contained, the amount of titanium oxide used can be saved.

えると不経済である。In the present invention, it is sufficient that the thickness of the surface layer is at least 0.5 mm. If the thickness is less than 0.5 mm, it becomes difficult to form the surface layer uniformly, and the amount of titanium oxide is insufficient, so that the photocatalyst is insufficient. The function cannot be performed. In addition, in both cases where the titanium oxide is contained only in the surface layer and when the titanium oxide is contained in the entire roofing material, the amount of titanium oxide is 5 to 5 parts per 100 parts by weight of cement in the portion corresponding to the surface layer. Preferably 50 parts by weight
If it is less than 50 parts by weight, it is difficult to achieve the object, and if it exceeds 50 parts by weight, it is uneconomical.

The kneaded material (mortar) mixed at a weight ratio of 2 is filled in a mold, pressed and steam-cured. In the present invention, the titanium oxide is added to the entire kneaded material filled in the mold. Alternatively, a kneaded material for the surface layer may be separately prepared, and titanium oxide may be added to only this. Also, instead of preparing the kneaded material for the surface layer, prepare a mixed powder of cement and titanium oxide, spray it, and press it with a roller to absorb water from the lower kneaded material or separate water. May be replenished. When a pigment or pottery component is formed on the surface of the cement tile together with the base material, titanium oxide can be added to the pigment or pottery component.

And
The roof is less likely to accumulate dust than a pavement, and even if it accumulates, it is easy to wash away due to rain because it has a slope, and people and cars do not pass, and sunlight is less blocked in other buildings, so The photocatalytic function of titanium oxide works efficiently to purify the atmosphere.
