以下、本発明についてさらに詳細に説明する。   Hereinafter, the present invention will be described in more detail.

本発明で用い得る天然石としては、石灰石、大理石、御影石、凝灰石、砂岩、蛇紋石などが例示されるが、これらに限定されるものではない。   Examples of natural stones that can be used in the present invention include, but are not limited to, limestone, marble, granite, tuff, sandstone, and serpentine.

この天然石は、1辺が10〜200cmの正方形ないし長方形の板状に切断加工され、必要に応じ研磨されて建材本体とされる。建材本体の厚さは1〜5cm程度が好適である。   This natural stone is cut into a square or rectangular plate shape with a side of 10 to 200 cm, and is polished as necessary to form a building material body. The thickness of the building material body is preferably about 1 to 5 cm.

建材本体の表面には、例えば図1に示すように、面積割合として0.5〜10%程度となるように多数の穴1があいていることが好ましい。穴の深さは1mm以上であることが好ましい。穴は建材本体を貫通していないことが望ましい。   For example, as shown in FIG. 1, it is preferable that a large number of holes 1 are formed on the surface of the building material main body so that the area ratio is about 0.5 to 10%. The depth of the hole is preferably 1 mm or more. It is desirable that the hole does not penetrate the building material body.

この建材本体の穴に保持させる蓄光材としては、各種希土類系蓄光材(アルミン酸ストロンチウム+ユーロピウム,ネオジムドープ。アルミン酸カルシウム+ユーロピウム,ジスプロシウムドープなど。)や、硫化亜鉛+銅ドープなどを用いることができる。蛍光材としてはフルオレセイン系、スチルベンゼン系、各種希土類蛍光材などを用いることができる。   Use various rare earth-based phosphorescent materials (strontium aluminate + europium, neodymium doped, calcium aluminate + europium, dysprosium doped, etc.), zinc sulfide + copper doped, etc. Can do. As the fluorescent material, fluorescein-based, stilbene-based, various rare earth fluorescent materials, and the like can be used.

蓄光材及び/又は蛍光材は、穴の内面にのみ担持されてもよく、目止め材に混合されて目止め材と共に穴に充填されてもよい。穴の内面にのみ担持されている場合、明るい場所における外観に通常の天然石建材と変わりなく、夜間もしくは光照射した時のみ穴が光る。したがって、天然石の穴の奥行き、つまり立体感を損なうことなく、蓄光材及び/又は蛍光材を使用できる。   The phosphorescent material and / or the fluorescent material may be supported only on the inner surface of the hole, or may be mixed with the sealing material and filled in the hole together with the sealing material. When it is carried only on the inner surface of the hole, the appearance in a bright place is the same as a normal natural stone building material, and the hole shines only at night or when irradiated with light. Therefore, the phosphorescent material and / or the fluorescent material can be used without impairing the depth of the natural stone hole, that is, the three-dimensional effect.

蓄光材及び/又は蛍光材を例えば図2(a)のように、穴の内面にのみ担持させるには、蓄光材及び/又は蛍光材のスラリーをスプレー、刷毛塗り、ディッピングなどにより建材本体の表面に付着させた後、穴以外の建材本体の前面の平坦部に付着したスラリーを拭き取るのが好適である。   In order to carry the phosphorescent material and / or fluorescent material only on the inner surface of the hole as shown in FIG. 2 (a), for example, the surface of the building material main body is sprayed, brushed, dipped, etc. by slurrying the phosphorescent material and / or fluorescent material It is preferable to wipe off the slurry adhering to the flat part of the front surface of the building material main body other than the holes after being attached to the surface.

なお、例えば図2(b)のように、蓄光材及び/又は蛍光材の乾粉を穴に充填し、表面の余剰の乾粉を拭き取ることにより、穴に蓄光材及び/又は蛍光材の乾粉を充填してもよい。   For example, as shown in FIG. 2B, the hole is filled with dry powder of phosphorescent material and / or fluorescent material, and the dry powder on the surface is wiped off to fill the hole with dry powder of phosphorescent material and / or fluorescent material. May be.

蓄光材及び/又は蛍光材を例えば図2(c)のように、目止め材に混合しておく場合、目止め材としてはポルトランドセメント、白色セメント、ポリマーセメント、ポリスチレンなどを用いることができるが、これに限定されない。目止め材中には、蓄光材及び/又は蛍光材を乾燥時の重量%として3〜30重量%程度含有させておくことが望ましい。   When the phosphorescent material and / or the fluorescent material is mixed in the sealing material as shown in FIG. 2C, for example, Portland cement, white cement, polymer cement, polystyrene, or the like can be used as the sealing material. However, the present invention is not limited to this. In the sealing material, it is desirable to contain a phosphorescent material and / or a fluorescent material in an amount of about 3 to 30% by weight as a dry weight.

目止め材に蓄光材及び/又は蛍光材を添加してペースト状に混練した後、建材本体の前面の全体に塗り付けて建材本体の穴に充填し、次いで表面の余剰のペーストを拭き取ることが好ましい。   After adding a phosphorescent material and / or fluorescent material to the sealing material and kneading it into a paste, it can be applied to the entire front surface of the building material body, filled in the holes in the building material body, and then the excess paste on the surface can be wiped off. preferable.

上記のように蓄光材及び/又は蛍光材を穴内面に担持ないし充填させるか、又は蓄光材及び/又は蛍光材含有目止め材を穴に充填した後、乾燥させ、次いで透明コーティング層形成用の液を塗布して透明コーティング層3を形成するのが好ましい。この透明コーティング層を設けることにより、蓄光材及び/又は蛍光材や目止め材の保持の耐久性が向上する。透明コーティング層形成用の液としては、シリコン系コーティング液や、水ガラス、フッ素樹脂系コーティング剤、アクリル樹脂系コーティング剤、シラン系コーティング剤、ウレタン系コーティング剤、各種UV硬化樹脂コーティング剤などを用いることができるが、これに限定されない。   As described above, the phosphorescent material and / or the fluorescent material is supported or filled on the inner surface of the hole, or the phosphorescent material and / or the fluorescent material-containing sealing material is filled in the hole, and then dried, and then the transparent coating layer is formed. It is preferable to form the transparent coating layer 3 by applying a liquid. By providing this transparent coating layer, durability of holding the phosphorescent material and / or the fluorescent material and the sealing material is improved. As the liquid for forming the transparent coating layer, silicon-based coating liquid, water glass, fluororesin-based coating agent, acrylic resin-based coating agent, silane-based coating agent, urethane-based coating agent, various UV curable resin coating agents, etc. are used. However, the present invention is not limited to this.

なお、穴に蓄光材及び/又は蛍光材の乾粉を充填した場合には、通常は、この透明コーティング層を設けることにより乾粉の脱落を防止することが必要となる。   In addition, when the hole is filled with dry powder of phosphorescent material and / or fluorescent material, it is usually necessary to prevent the dry powder from falling off by providing this transparent coating layer.
