Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for making artificial wood or an inorganic building material, more specifically, the front and back surfaces of artificial wood, etc. having a color that is in tune with the pattern of a transfer paper, the mouth surface,
The present invention relates to a makeup method for artificial wood or an inorganic building material in which a pattern is transferred to a groove and a curved surface portion.

[0002]

2. Description of the Related Art Conventionally, the surface makeup method of artificial wood or inorganic building materials mainly composed of inorganic calcium silicate is
Laminating, router moulder processing, etc. Also,
Conventionally, in the makeup method of synthetic wood mainly composed of wood powder, the surface of the synthetic wood is preheated and the transfer paper is overlapped and cold pressed to transfer the pattern, and then the surface from which the transfer paper is peeled off is wiped. There is provided a method of filling ink in a recess or the like and applying a top coat if necessary (Japanese Patent Laid-Open No. 61-274933). This makeup method is
The purpose is to eliminate the surface irregularities of synthetic wood. In addition to this, as a makeup method for building materials, natural wood veneer pasting or natural stone slice pasting is performed.

[0003]

However, in the conventional makeup method for artificial wood and inorganic building materials, the surface coating,
Due to the laminating process and the like, it is difficult to express the subtle unevenness of the surface and the expression of wood and stone tones, and the thickness of the coating film and the sheet becomes thick, which may cause fire trouble. Further, in the method of applying the transfer paper to the synthetic wood, when transferring the transfer paper, the transfer paper is placed on the preheated base material, the transfer paper is pressure-transferred by the cold press, and the release paper is peeled off. In addition, there is a drawback that the preheat zone must be long in order to keep the substrate temperature of 100 ° C. or higher.

In addition, when natural wood veneer is stuck or natural stone is sliced, cracking and peeling are likely to occur, and the base color of artificial wood and inorganic building materials is exposed due to impact and scratches on the surface. The current situation is that it involves a lot of work, such as replacing. Therefore, an object of the present invention is to three-dimensionally express a pattern on the front and back surfaces of artificial wood or an inorganic building material, a wood mouth surface, a groove and a curved surface to give a real feeling and to preliminarily synchronize the surface color with a transfer paper pattern. It is an object of the present invention to provide a makeup method for artificial wood or an inorganic building material which is colored with the above-mentioned color and requires almost no repair or the like due to its unsightly appearance which is likely to occur due to impact or scratch on the surface.

[0006]

In the present invention, when a transfer paper pattern is transferred to the surface of an inorganic building material which is relatively difficult to make up under vacuum heat and pressure, and makeup is applied, a subtle unevenness, wood grain and stone tone are applied to the surface. Appears clearly. Further, the pattern from the transfer paper is thinly formed unlike painting or laminating, and there is almost no problem in fire prevention such as generation of dangerous gas due to fire or the like. Furthermore, when a colorant is uniformly mixed with the inorganic building material, it is possible to color the color in synchronization with the design of the transfer paper, and it is difficult for the appearance to be bad.
