DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a tuned polyester decorative board having on its surface a concavo-convex pattern matching a color pattern reproduced on a decorative board substrate.

[0002]

2. Description of the Related Art Conventionally, an unsaturated polyester resin is applied on a wooden base material, and thereafter, a shaping film having an uneven pattern is superimposed thereon to cure the unsaturated polyester resin, and thereafter, the forming film having the uneven pattern is applied. A method of manufacturing a decorative polyester sheet having an uneven surface by peeling a mold film is widely known as having a high reproducibility of the texture of a material.

In the method for producing a decorative polyester sheet having an uneven surface by the above-described method, a color pattern of a natural wood pattern is photographed to produce a printing master, and the color of the wood grain is printed by using the master. Duplicate the pattern on the decorative sheet. On the other hand, the unsaturated polyester resin is cured by using a mold made by molding a concave and convex pattern such as a conduit portion of a natural wooden pattern while synchronizing with the grain pattern of the decorative sheet, thereby forming the concave and convex pattern. There is a decorative board which is shaped and has a colorant adhered to the uneven surface to reproduce a natural woody texture by a wood grain color pattern printed on a decorative sheet and a shaped pipe pattern.

[0004]

However, in the above method, the color pattern of the grain of the natural wood replicated on the decorative sheet and the uneven pattern of the conduit portion or the like of one of the natural woods are matched. A method of manually registering the uneven pattern and the color pattern of the shaping film by hand from the back side of the shaping film and curing the unsaturated polyester resin in a state where the frame is fixed so that it does not shift is used. However, since the imprinting film is transparent or translucent, it is difficult to confirm the unevenness pattern of the conduit portion or the like. In particular, it is hardly observable when the film is adhered to the unsaturated polyester resin. Therefore, it is very difficult to completely align the color pattern with the concave and convex pattern such as the conduit portion, and there is a problem that it takes time and productivity is low. Alternatively,
Two circular holes are registered to one side of the natural wood manuscript.
At least one metal piece is provided, and these are integrated to form an original for a shaped film and a decorative sheet, and the projections formed on the shaped film are fitted into holes formed in a decorative plate material such as a decorative sheet. Accordingly, a method of matching the color pattern reproduced on the decorative sheet with the concave and convex pattern of the imprinting film has been proposed, but has a disadvantage that productivity is poor and the method is not suitable for mass production.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a synchronous pattern in which a color pattern reproduced on a decorative sheet and a concavo-convex pattern such as a conduit portion of a shaping film are well matched. A method of manufacturing a polyester decorative board, and a method of producing a tuned polyester decorative board, in which a color pattern reproduced on a decorative sheet and a concavo-convex pattern such as a conduit portion of a forming film can be accurately and quickly matched with each other. This is to provide a mold film.

[0006]

In order to achieve the above object, a method for producing a tuned polyester decorative board according to the present invention comprises:
An unsaturated polyester resin liquid is applied on a decorative material having a natural wood or natural veneer color pattern formed thereon, and the conduit groove pattern of the natural wood or natural veneer is formed on the surface of the unsaturated polyester resin liquid. In the method for producing a decorative polyester plate obtained by curing the molded film placed in contact with the irregular surface of the mold film and then peeling the molded film, as the molded film, at least two or more arbitrary locations By using a colored shaping film having a colored convex portion made of a colored silicone resin formed at a location, the color pattern of the natural wood or natural veneer matches the conduit groove pattern. is there.

The colored imprinting film used in the present invention is composed of a natural wood or a natural veneer having an uneven pattern on its surface as an original, and at least two or more concave portions on the uneven surface of the original. Only after applying a colored silicone resin, and then applying a transparent or translucent silicone resin to the entire surface including the applied colored silicone resin surface,
The colored silicone resin and the transparent or translucent silicone resin are cured and integrated, and thereafter, the cured and integrated silicone resin film is released from the mold to form a molded product.

[0008]

The colored film according to the present invention is provided with a colored portion on the convex portion of the film, so that when the film is overlaid on a color pattern, the uneven pattern of the film can be easily recognized. Therefore, it is easy to match the position of the color pattern on the decorative sheet. In addition, since there are two or more colored portions, alignment can be performed at the same time, and it is easy to completely match the whole.
