The present application relates to an ocher board which is provided as a building interior material by impregnating an ocher component in a nonwoven fabric.

Since ancient times, our ancestors wanted to find and use the building materials needed to build a house in nature, mainly using wood, soil, and stone. Tiles were made by baking soil, thatched roofs were made by weaving straw, walls were made of ocher, and floors. The ondol structure has been favored by a thin stone plate with a large area as a saddle field.

Ocher absorbs moisture when humidity is high, and when it dries, it absorbs moisture and automatically adjusts the surrounding humidity. It also quickly absorbs harmful odors such as food, tobacco, and other deodorant effects. It is known to have the function of preventing the habitat of various fungi harmful to the fungus and the human body, and absorbing and neutralizing the harmful substances to the human body.

In addition, ocher is a substance that emits far-infrared rays that act to stimulate the circulation of blood, promote metabolism, activate cellular functions, and promote growth while purifying the surrounding environment while living and breathing microorganisms that are beneficial to the human body. Im known.

However, despite the excellent function as mentioned above, ocher has relatively low strength, and after drying, it is relatively weak instead of ocher soil or wood because it is broken or cracked due to weak bonding strength with other materials. High strength and high binding strength cements and steels are being used. Furthermore, in order to give durability and adhesion to interior building materials, modern volatile organic compounds are used. It has been found to be the cause of indoor syndromes such as headache, vomiting and allergies (heaven, atopy) .In the cement used in Korea, a large amount of hexavalent chromium is detected, and harmful substances in the cement can cause fatal harm to humans. As the contents of the report are reported through the media, Has surprised people, but at the moment it does not provide materials to replace cement or existing interior materials.

In addition to cement, which is the basic material in modern buildings, building materials that have been used for building flooring, walling, and ceiling materials have been found to be the cause of so-called sick house syndrome. This newly mentioned, ocher ondol room, ocher wallpaper, ocher boards, etc. are beginning to spread, but have not yet provided a product that satisfies the needs of consumers in reality.

We started with the task of providing ocher board products that can be used as eco-friendly building materials while absorbing and eliminating the causative agents causing house syndrome as building interior materials and solving the toxicity problems of cement. It is an eco-friendly building material with easy insulation and flame retardancy. The ocher board is provided by impregnating, coating, laminating and drying ocher on a non-woven fabric in the process of experimenting the possibility of using it as a substitute for indoor wallpaper or as a ceiling material. It was confirmed that the expected effect can be obtained to complete the invention.
