Description
【０００１】[0001]
本考案は遮光装置に関し、もっと詳しくは光活性触媒の酸化作用により大気汚 染物を分解することができる遮光装置に関する。 The present invention relates to a light shielding device, and more particularly, to a light shielding device capable of decomposing atmospheric pollutants by an oxidizing action of a photoactive catalyst.
【０００２】[0002]
従来、建物や車内などへの日光の直接的照射を防止するために、建物や車内な ど、特に窓ガラスの内側に、日よけやカーテンなどの遮光装置が取り付けられる ことがあり、この遮光装置により、日光を遮る機能を果たすことができる。 Conventionally, in order to prevent direct irradiation of sunlight on buildings and vehicles, light-shielding devices such as sunshades and curtains have been attached to buildings and vehicles, especially inside the window glass. The device can perform the function of blocking sunlight.
【０００３】[0003]
しかしながら、大気汚染が酷い今日では、室内の通気の要路にある遮光装置は 、大気における水分や塵などの汚染物に付着されやすいので、人間の体に悪い影 響をもたらす細菌や黴が繁殖しやすく、またホルムアルデヒド・二酸化硫黄・ア ンモニアなどの有害物質や他の環境ホルモンも発生、蓄積しやすいと言う欠点が ある。 However, today, when air pollution is severe, the light-shielding device in the main ventilation path of the room easily adheres to contaminants such as moisture and dust in the atmosphere, and bacteria and fungi that have a bad effect on the human body grow. It has the drawback that it is easy to produce and accumulates harmful substances such as formaldehyde, sulfur dioxide, ammonia and other environmental hormones.
【０００４】 上記に鑑み、本考案の目的は、大気汚染物を酸化分解させることができる遮光 装置を提供しようとすることにある。[0004] In view of the above, an object of the present invention is to provide a light shielding device capable of oxidizing and decomposing air pollutants.
【０００５】[0005]
上記目的を達成するために、本考案は、窓ガラスの内側に取り付けて光を遮る ためのものであって、光に面する前面部と、該前面部と反対する側にある背面部 とからなる遮光装置において、前記前面部と前記背面部とのうちの少なくとも一 つには、大気汚染物を酸化分解させる光活性触媒を含有する光触媒皮膜層が形成 してあることを特徴とする遮光装置を提供する。 In order to achieve the above object, the present invention is mounted on the inside of a window glass to block light, and comprises a front part facing light and a rear part on the side opposite to the front part. A light-shielding device comprising a photocatalyst film layer containing a photoactive catalyst for oxidizing and decomposing air pollutants on at least one of the front part and the rear part. I will provide a.
【０００６】 上記構成によると、本考案の遮光装置面上における光触媒皮膜層に含有する光 活性触媒は、日光中の紫外線によって刺激されて光活性を発揮し、汚染物を酸化 させることができるので、前記遮光装置に付着した大気汚染物を分解することが できる。According to the above configuration, the photoactive catalyst contained in the photocatalytic film layer on the light-shielding device surface of the present invention can be activated by ultraviolet rays in sunlight to exhibit photoactivity and oxidize contaminants. In addition, air pollutants attached to the light shielding device can be decomposed.
【０００７】[0007]
先ず、図１及び図２を参照しながら、本考案に係る遮光装置の好ましい実施形 態を説明する。本実施形態において、遮光装置１は車の窓ガラスＡに取り付けら れているが、建物における窓ガラスの内側に取り付けられてもよい。且つ、前記 遮光装置１は発泡材からなる波形シート１０をその本体とし、且つ光に面する前 面部１１と、該前面部１１と反対する側にある背面部１２とを有する。 First, a preferred embodiment of the light shielding device according to the present invention will be described with reference to FIGS. In the present embodiment, the light shielding device 1 is attached to the window glass A of the car, but may be attached to the inside of the window glass in the building. The light-shielding device 1 has a corrugated sheet 10 made of a foam material as its main body, and has a front surface portion 11 facing light, and a back surface portion 12 on a side opposite to the front surface portion 11.
【０００８】 そして、図１及び図３それぞれに示す符号３は前記前面部１１に形成されてい る光触媒皮膜層である。この光触媒皮膜層３は、光活性触媒としてのＴｉＯ2 を バインダとしてのアルカリ珪酸塩、例えば、カリウム系珪酸塩に添加混合してな る被覆組成物を前記前面部１１に塗布．乾燥してなるものである。なお、前記光 活性触媒としては、前記ＴｉＯ2 に代えて、ＺｒＯ2 、ＺｎＯ、ＷＯ3 、または ＳｒＴｉＯ3 を使用してもよい。更に、光を反射するよう、前記前面部１１と前 記光触媒皮膜層３との間には反射層１３が設けられている。Reference numeral 3 shown in each of FIGS. 1 and 3 denotes a photocatalytic film layer formed on the front surface portion 11. The photocatalyst coating layer 3 is formed by applying a coating composition obtained by adding and mixing TiO 2 as a photoactive catalyst to an alkali silicate as a binder, for example, a potassium silicate. It is made by drying. As the photoactive catalyst, ZrO 2 , ZnO, WO 3 , or SrTiO 3 may be used instead of TiO 2 . Further, a reflection layer 13 is provided between the front surface portion 11 and the photocatalytic film layer 3 so as to reflect light.
【０００９】 そして、図４に示すように、日光中の紫外線が前記光触媒皮膜層３に照射する と、前記光触媒皮膜層３に含有するＴｉＯ2 は刺激されて正孔が形成されるので 、この正孔による酸化−還元の作用により、前記遮光装置１に付着した大気汚染 物が酸化分解され得る。Then, as shown in FIG. 4, when ultraviolet rays in sunlight irradiate the photocatalyst coating layer 3, the TiO 2 contained in the photocatalyst coating layer 3 is stimulated to form holes. The air pollutants attached to the light shielding device 1 can be oxidized and decomposed by the action of oxidation-reduction by holes.
【００１０】 また、遮光装置の本体として、本実施形態においては、発泡材からなる波形の シートが使用されているが、これに代えて、網状のシート、鎧板などを使用して もよい。以下、本考案に係る遮光装置の他の好ましい実施形態を説明する。In this embodiment, a corrugated sheet made of a foam material is used as the main body of the light-shielding device, but a net-like sheet, armor plate, or the like may be used instead. Hereinafter, other preferred embodiments of the light shielding device according to the present invention will be described.
【００１１】 図５に示す実施形態における遮光装置２は複数枚の遮光装置本体としての鎧板 ２０からなるブラインドである。前記鎧板２０は前記実施形態と同様に、光に面 する前面部２１と、該前面部２１と反対する側にある背面部２２とを有する。前 記実施形態と同様な方法で前記鎧板２０の前面部２１及び背面部２２の両面には すべて光触媒皮膜層３が形成されている。このように、日光中の紫外線が前記鎧 板２０に照射すると、前記光触媒皮膜層３に含有する光活性触媒は刺激されて正 孔を形成するので、この正孔により、前記遮光装置２に付着した大気汚染物が酸 化分解され得る。The light shielding device 2 in the embodiment shown in FIG. 5 is a blind including a plurality of armor plates 20 as light shielding device main bodies. The armor plate 20 has a front part 21 facing the light and a back part 22 on the side opposite to the front part 21, as in the embodiment. The photocatalyst coating layer 3 is formed on both surfaces of the front part 21 and the back part 22 of the armor plate 20 in the same manner as in the above embodiment. As described above, when ultraviolet rays in sunlight irradiate the armor plate 20, the photoactive catalyst contained in the photocatalytic film layer 3 is stimulated to form holes. Air pollutants can be oxidatively decomposed.
