Description

Manufacturing method for an Ocher plate member}

The present invention relates to a loess plate used in the construction of residential buildings such as apartments, restaurants, oriental hospitals, jjimjilbang, sauna, etc., in particular, can prevent the sick house syndrome, excellent thermal insulation, soundproofing and flame retardant and natural-friendly loess It relates to a method for producing a plate.

Ocher boards widely used as building materials for residential buildings take advantage of scientifically proven loess, which emits large amounts of far-infrared radiation, which stimulates and activates molecules in the living body when it is absorbed in biochen. Efficacy in warming the living body and maintaining the freshness of foods.It contains catalase that removes hydrogen peroxide, neutralizing lipid peroxide, which is a toxin in the body, and also contains a protease that hydrolyzes proteins into amino acids. It also has efficacy.

By utilizing the efficacy of such loess, the loess has been used in various construction materials as well as real life products and health appliances.

In addition, wood and gypsum board are used as materials for walls, ceilings, and floors in buildings, but wood is easily deformed due to weakness of moisture, and is highly flammable, which makes it difficult to extinguish during fire. As it is manufactured, indoor air cannot be moved to the outside due to the limit of insulation and ventilation, and it contains harmful ingredients such as asbestos, and it causes problems of environmental pollution such as soil and water when treating waste.

Therefore, in recent years, various attempts have been made to use ocher as a building finishing material. For example, it is a product in the form of a dough that is applied to the floor, ceiling, or wall of an ocher room, an ocher jjimjilbang, an ocher sauna, and the like. However, such conventional ocher products have a lot of cracks after construction and easily fall off from the construction surface, and they are inconvenient in construction.As a solution to this, ocher and back cement or ocher and resin (adhesive) and I am using mixed products.

Mixing chemicals to prevent cracking in such conventional ocher products would detract from the original purpose of the loess for health and would rather benefit from not using such ocher.

In addition, in traditional buildings, it is widely used as a finishing material for walls or roofs by utilizing the peculiar properties of ocher. However, due to its weak bonding strength, it is usually weak to moisture and has a high surface strength. The work using plaster was required to compensate for the low weathering easily, and the technique of blending seaweed grass as an adhesive material was developed to improve strength and adhesion in building materials using ocher. The problem that the adhesive force is damaged by the corruption still occurred.

Moreover, recently, carcinogenic substances such as benzene, toloene, chloroform, acetone, and formaldehyde are emitted from building materials and wallpaper used in the construction of residential apartments, and contaminants such as asbestos, fine dust, and floating bacteria generated during construction The substance is also not released to the outside and accumulates indoors, causing so-called Sick House syndrome. When a person is exposed to such pollution, various diseases and dizziness are caused.

The present invention has been made to solve the various problems in the prior art as described above and problems occurring in the construction of new apartments, such as sick house syndrome, can reduce the weight of the ocher plate, improve the strength and maintain excellent adhesion to crack It is an object of the present invention to provide a method for producing ocher plate material which can eliminate occurrence.

In addition, the present invention has another object to provide an environmentally friendly ocher plate manufacturing method that can prevent the sick house syndrome occurs when moving into a new apartment.

In order to achieve the objects of the present invention as described above, in the present invention, ocher powder and fly ash (Fly Ash) in the range of 45 to 55% by weight and 32 to 38% by weight, respectively, and bentonite 8 to 12% by weight Supplying and mixing 2.5% to 3.5% by weight of kaolin;
