樹脂で表面被覆を施した大谷石に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention is directed to the use of Oya stone, which is used as a building material and a decorative material, whose surface is coated with a transparent synthetic resin in order to maintain its original beauty and prevent it from weathering. Regarding Oyaishi.

門柱、玄関、池等、多方面に使用されている。Oya stone is a famous stone that is cut from underground layers in the Okama region of Tochigi Prefecture, and its origins date back to a time when most of the Japanese archipelago was underwater, with some parts protruding above the sea. Oya stone is said to be the result of a large number of rhyolitic breccias (quartz trachyte) volcanic ash and gravel ejected from the eye, settling in seawater and solidifying. The stone is fireproof,
It has strong earthquake resistance, excellent dryness and moisture resistance, is light and heavy (specific gravity 1.99), and is easy to process, making it extremely versatile as a stone for civil engineering and construction. In particular, the bluish pattern immediately after it is produced from the underground layer is elegant and highly preferred as a building material and decorative material, and is used for civil engineering construction, sports facilities, stone walls, etc.
It is used for many purposes such as gateposts, entrances, and ponds.

耐久性及びその美感が要求されていた。The highly decorative pattern of Oya stone is caused by the presence of bluish ferric iron (Fe SO4, nH, o) in the white tuff, but it is also caused by the presence of underground layers. After being mined and exposed to the air, its color changes over time and undergoes a process of weathering, so it is required to be durable and beautiful as a building and decorative material.

る。[Means and effects for solving the problems] The present invention has been made in view of the above, and is intended to maintain the color tone of the surface of Oya stone that has already been constructed or cut out to the user's preference, or to change the color tone as desired. In order to stop the color change at these points and prevent the Oya stone block from weathering when oxidation progresses, a transparent synthetic resin was applied to the surface of the Oya stone at any point during the color change process. It provides Oya stone.
以下本発明による表面被覆を施した大谷石を説明する。 Oya stone with a surface coating according to the present invention will be explained below.

維持できなくなる。The block-shaped Oya stone, which is mined by open pit or inland trenches from pewter or Yoguchi laminated rocks buried underground, contains a large amount of water, and has a bluish ferric tuff to the white tuff described above. (Fe -8o4·nH□0) is scattered. When this mottled pattern comes into contact with the air, the moisture dries and changes over time to brownish-brown ferric (Fe(Of)). As the oxidation progresses further, ferric iron changes to Fe (OH).

As the surrounding tuff weathers, the original shape of the block material cannot be maintained.
