Disclosed is a method for producing an ocher-coated interior plate material for preventing the cracks and desorption of an ocher layer which is coated on an interior plate material installed on the surface of an indoor living space wall. To this end, in the present invention, fine ocher powder and ceramic powder for compensating for the brittleness of the ocher powder are dissolved and made to permeate into a base material at high pressure, so that the interior plate material is coated while pure ocher is exposed on the surface thereof. In the present invention, ocher powder which is pulverized to have a minute particle size is used as a main material, and ceramic powder for controlling brittleness is used as a sub-material or tourmaline powder is added, so as to be provided to a spraying gun which sprays a flame by means of a combustible gas along with compressed air. Accordingly, when the flame reaches the surface of the base material, ocher and ceramic are dissolved in order to permeate into the surface of the interior plate material at high pressure, so that a film layer is formed at an appropriate thickness and an ocher-coated interior plate material which does not have cracks or desorption can be produced. |
