A conventional method for manufacturing artificial wood of this kind is disclosed in Korean Patent Publication No. 1981-0000871.

The manufacturing method of the artificial wood disclosed in the Korean Patent Publication No. 1981-0000871 is a manufacturing method of the water-resistant tough artificial wood made to form a water-resistant, tough water-resistant artificial wood using a straw mainly harvested in rural areas In the pulverizer, a straw-shaped straw straw having a diameter of 1-2 mm and a length of 3-4 cm is made into capillary powder, and then 60% by weight of the capillary powder and 40% by weight powder of synthetic resin raw materials such as polyethylene vinyl or PVC and nylon are mixed. The mixture was heated and kneaded at 150-180 ° C. in a vacuum furnace in which the mixture was not burned, and then rolled with a three-stage roller to form a high pressure mold in a predetermined mold.

By the way, the artificial wood produced by the conventional artificial wood manufacturing method contains 60% by weight of the capillary powder made by grinding the crest, the elasticity is good, but it can be burned, the durability is weak, etc. In addition to the problems, there are various problems, such as the production of large panels by twisting, heavy, poor workability.

In addition, the artificial wood produced by the conventional artificial wood manufacturing method contains powder synthetic resin raw materials such as nylon type, there is a problem that not only can not prevent the development of atopic syndrome, but also can cause respiratory diseases, In addition, there is a variety of problems, such as non-combustible material can not prevent the fire, and can not maintain the health of the human body because it does not emit negative ions and far infrared rays.

Accordingly, the present invention has been made to solve the above various problems, and an object of the present invention is to provide a method of manufacturing an artificial ceramic panel that can be used as a substitute for wood.

Another object of the present invention is to provide a method of manufacturing an artificial ceramic panel that can maintain the health of the human body by emitting anion and far infrared rays.

Another object of the present invention is to provide a method of manufacturing an artificial ceramic panel that can prevent the development of atopic syndrome (birdhouse syndrome).

Another object of the present invention is to provide a method of manufacturing an artificial ceramic panel that can preserve the natural ecosystem and protect the natural environment.

Still another object of the present invention is to provide a method of manufacturing an artificial ceramic panel which can prevent fire as a nonflammable material.
