Prior interior panels, which are manufactured by soaking asbestos and chemical additives in water and drying the soaked materials, are sensitive to changes in the weather. Thus, these interior panels have many problems in that the inside thereof gets moist with the passage of time, and thus the appearance thereof is deteriorated, the strength thereof is reduced, materials harmful to the human body are emitted from the panels, and additional finishing operations are carried out after the construction of the panels, leading to an increase in the construction period. In addition, the interior panels cause environmental contamination when they are discarded after use. Moreover, prior interior panels, which are manufactured according to methods other than the above- described method, have problems in that they are heavy, thus increasing the load on buildings, leading to an increase in the building construction costs.

Best Mode for Carrying Out the Invention
[8] Hereinafter, a preferred embodiment of the present invention will be described in detail.
[9] The inventive method for manufacturing an interior panel for building non-bearing walls or partitions comprises a step of heating 35 wt% of an expandable mineral perlite at 1100 0 C to expand it about 12 times (specific gravity of 0.18), heating 25 wt% of flexible vermiculite at 600-700 0 C to expand it about 40-50 times (specific gravity of 0.05), grinding the expanded perlite and vermiculite to a particle size of less than 2.5 mm, and then adding 10 wt% of woody fiber and 5 wt% of activated fiber to the particles (step 1).
[10] Herein, the perlite that is used in the present invention is obsidian formed when volcanic rocks are rapidly cooled. When the perlite is heated to a high temperature, water contained in the perlite evaporates, while the perlite expands, so that it becomes a fine, porous white mineral. The perlite has a neutral pH and contains little or no nutrients, and weeds, seeds, germs and noxious insects do not inhabit the perlite.
[11] Also, the vermiculite that is used in the present invention is a mineral produced by the weathering or hydrothermal alteration of biotite, and is divided, according to quality, into vermiculite gold and vermiculite silver. It contains water molecules bound therein, and thus when it is heated to a high temperature, innunerable pores are formed therein due to air bubbles formed during the evaporation of water in the mineral, and it expands to a volune 40-50 times that of the raw ore.
[12] The environment- friendly perlite and vermiculite are three-layered mica- like minerals, and contain water between the layers thereof. Thus, when they are heated, dehydration between the layers thereof occurs, and they thermally expand, so that they serve as a thermally insulating, soundproof inorganic material having innunerable pores therein.
[13] Then, 8 wt% of ore powder, 5 wt% of pulp and 2 wt% of starch powder are mixed with a 2.5-fold weight of water and heated at 100 0 C to obtain a material having excellent flame-retardant properties (step 2).
[14] Then, the mixture of step 1 and the mixture of step 2 are mixed and kneaded with 10 wt% of an inorganic adhesive, and are molded with a vibrating press. Then, the molded board-shaped product is pressed and dried in a hot press at 160-180 0 C at a pressure of 5 kg/cm 2 .
[15] Then, a step of treating the surface of the dried interior panel is carried out. In this step, a solution consisting of powder, obtained by grinding pulp and perlite to a size of 130 mesh, starch powder, various ore powders, a neutral dye such as plant dye, and an inorganic adhesive, is sprayed on the outer surface of the interior panel. The sprayed material is cured and dried, the surface of the resulting interior panel is polished, and the polished interior panel is packaged. In this way, the interior panel can be manufactured.
[16] Herein, the solution has a function of increasing strength and a heat sink function, when it is dried in contact with air. Thus, the solution can effectively prevent the chemical corrosion or thermal deformation of the constructed interior panel, and can improve the aesthetics of the interior panel such that additional finishing operations are not required.
