にした可撓性シートを提供することを目的とする。Zero-Hatsu Ijlihiro was created with this in mind, and is a flexible material whose transparency changes by mixing fine particles of a substance whose original absorption wavelength changes depending on the amount of ultraviolet rays in the glass. The purpose is to provide sex sheets.
以下、本発明を図面に基づいて説明する。Hereinafter, the present invention will be explained based on the drawings.

触がおきないようにしている。When fine particles of silver chloride are directly mixed into a flexible sheet, for example, a vinyl chloride sheet, the air that enters inside the flexible sheet 1 due to its breathability causes the fine particles of silver chloride to be mixed directly into the flexible sheet. When silver chloride is oxidized, it changes to a crystalline structure that reflects the original wavelength.
As a result, the transparency of the flexible sheet changes and does not become transparent again. Therefore, in the present invention, as shown in an enlarged view of the silver chloride fine particles 2 in FIG. 1, the silver chloride fine particles 2 have a structure covered with glass 3.
Air entering the sheet is prevented from coming into contact with the silver chloride fine particles 2.

ト内に混ぜ込むようにすればよい。In order to infiltrate the glass 3 with silver chloride particles 2 in this way, the company first mixed silver chloride particles into the glass to produce a glass plate, and then coated the glass plate with predetermined particles. The glass may be crushed or formed into granules (round beads) until it is obtained, and this powder may be mixed into the flexible sheet when it is produced.
１ｇ２図社本社本発明の実施例を示した図である。1g2 Zusha Head Office FIG. 1 is a diagram showing an embodiment of the present invention.
この実施例は、塩化銀の微粒子２を混在した塩化ビニー
ルシート１の両面に、通気性の低い可撓シート４を貼着
したう之ネート構造を有することを特徴とする。This embodiment is characterized by having a uniform structure in which flexible sheets 4 with low air permeability are attached to both sides of a vinyl chloride sheet 1 mixed with fine particles 2 of silver chloride.

子が酸化されることはない。According to this embodiment, the flexible sheet 1 containing the fine particles 2 of precipitated silver chloride is covered from both pages by the flexible sheet 4 with low air permeability.
Since there is almost no air circulation, the fine particles of silver chloride are not oxidized.

次に本発明による可撓シートの用途を説明する。Next, the use of the flexible sheet according to the present invention will be explained.

ものである。As explained above, according to the present invention, since fine particles of a substance whose absorption wavelength of light changes depending on the amount of ultraviolet rays absorbed are present inside the flexible sheet, when ultraviolet rays are absorbed, the ultraviolet rays The transparency changes depending on the amount, that is, it has a predetermined coloring effect that reduces visibility, and it can be applied to the window glass of a vehicle to prevent direct sunlight, or it can be applied to the window glass of a building or house to create a curtain. It can also be used as In particular, when used for vehicle window glass, it is completely transparent because it is not exposed to ultraviolet rays when driving at night.
Ensure sufficient visibility. Furthermore, it has an extremely excellent effect that it can be used for agriculture or commercial purposes.
