Description

[Detailed description of the invention] <Industrial field of application> The present invention relates to a stained glass-like decorative board made of synthetic resin. To provide something that can be kept thin.

<Prior art> The basic structure of the synthetic resin decorative board to which the present invention is applied is, for example, as shown in FIGS. 1 to 7.
A pattern layer 1 and a reinforcing layer 2 are made of synthetic resin, and a colored layer 4 is filled in an area surrounded by a raised raised border 3 of a predetermined pattern to form a pattern layer 1, and one side is made flat. This is a type in which the pattern layer 1 is bonded to the other surface of a light-transmitting reinforcing layer 2.

As a conventional example of this format, for example,
As shown in Publication No. 21112, the pattern layer is made of a thixotropic high-viscosity synthetic resin that hardens at room temperature.
In addition, each reinforcing layer is formed of a transparent synthetic resin plate such as polystyrene, and a border is formed by drawing an arbitrary design in a raised shape on the reinforcing layer using unsaturated polyester resin or the like having sag-preventing properties. The area surrounded by this border is filled with a colored synthetic resin to form a colored layer, and before the colored layer is completely dry, thin metal pieces or small pieces of metallized film are interspersed and adhered. There is.

<Problems to be solved by the invention> In the above-mentioned conventional technology, the thin metal plate etc. exhibits a beautiful appearance due to diffuse reflection, but the surface of the pattern layer is formed with many unevenness, and depending on the condition of the light beam, the unevenness may The surface is shiny, the edges are dull, and the design lacks clarity.

In particular, when the decorative board is used as stained glass, the colors of the border and colored layer are not vivid when viewed directly from the pattern side, and when the pattern layer is seen through the transparent reinforcing layer. In reality, the pattern was not very clear due to the uneven surface on the back.

In addition, the decorative board must have a certain level of strength, but this strength is determined by the thickness of the concave part of the pattern layer and the reinforcing layer, so the protruding part of the pattern layer will cover the entire decorative board. From that point of view, it was becoming bulkier, and the cost of materials was wasted accordingly.

Moreover, since the synthetic resins constituting the pattern layer and the reinforcing layer are different, the pattern layer often peels off from the reinforcing layer when the decorative board changes over time or is processed.

The technical problem of the present invention is to solve the above problems.

<Means for Solving the Problems> Means for solving the above problems will be described below with reference to FIGS. 1 to 7, which correspond to embodiments.

That is, the border portion 3 is made of the same synthetic resin that has thixotropy at room temperature, and the colored layer 4 and reinforcing layer 2 are made of the same kind of synthetic resin, and the surface 5 of the border portion 3 and the colored layer 4 is made flat. It is formed flush.

<Function> Since the surface 5 of the border portion 3 and the colored layer 4 is formed in a flat, flush shape, light is not diffusely reflected on the surface 5, and the colors of the border portion 3 and the color layer 4 appear vivid.

This also applies when the pattern layer 1 is seen through the transparent reinforcing layer 2, and since the surface 5 is flat, the pattern becomes clear.

Moreover, since the pattern layer 1 and the reinforcing layer 2, which constitute the colored layer 4 and the border portion 3, are formed of the same type of synthetic resin, the compatibility between both layers 1 and 2 is large, and the bonding strength can be maintained at a high level.

<Effect of the invention> The colors of the edges and colored layers are vivid even when the decorative board is viewed from both the front and back, so if it is used for something that can be viewed from either the front or the back, such as stained glass, for example, Particularly suitable.

Moreover, since the edges and the colored layer surfaces are made flat, the thickness of the entire decorative board is constant, and as long as the wall thickness necessary for the decorative board is formed, there will be no convex parts on the pattern part. The entire board does not become bulky due to the lack of it, and material costs can be reduced.

Furthermore, since the pattern layer and the reinforcing layer have a strong affinity, there is no risk that the pattern layer will peel off from the reinforcing layer even during processing or aging, making it possible to produce a decorative board with stable quality.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

Figure 1 is a vertical cross-sectional front view of the synthetic resin decorative board, Figure 2
The figure is a plan view of the decorative board, and FIGS. 3 to 7 are explanatory diagrams sequentially showing the manufacturing process of the decorative board. The decorative board 10 consists of a pattern layer 1 and a reinforcing layer 2. is composed of a border portion 3 and a colored layer 4.

The edging portion 3 is made of a high viscosity synthetic resin that is thixotropic at room temperature, such as (1) unsaturated polyester resin (for example, polyethylene maleate copolymerized with styrene monomer), (2) epoxy resin, and (3) diallyl. Phthalate resin can be used, and transparent resin can also be used.
Preferably, it is colored black or dark.

This edging portion 3 is a member that constitutes the pattern of the pattern layer 1, and is also an important element that determines the basic thickness of the pattern layer 1.

The colored layer 4 is made of the same kind of synthetic resin as the edging part 3, but thixotropy is not required (more fluidity is preferable), and the colored layer 4 is made of a translucent material colored with a desired coloring agent. Therefore, it is preferable that the material has good air curability and a small shrinkage rate.

The reinforcing layer 2 is made of the same kind of synthetic resin as the colored layer 4, and may be formed colorless and transparent without using a colorant, or may be formed on a transparent surface with a pale yellow, blue, or red color, for example. There is no problem.

The actual method for manufacturing the decorative board will be described below.

(1) As shown in Fig. 3, a container 8 made of a transparent synthetic resin film is formed into a box shape by raising the four edges 7 on a picture paper 6 on which a predetermined picture, pattern, etc. is drawn. Put on.

The box-shaped film 8 has a property that it has some adhesive strength with the synthetic resin that is the material of the above-mentioned border portion 3 and the colored layer 4 before it is cured, and that it is easy to peel off from each other after it is cured. For example, (i) Tetron film, (ii) polyester film, and (iii) nylon film are preferred.

It goes without saying that the picture paper 6 is not required when a design is drawn directly on the box-shaped film 8.

(2) As shown in FIG. 4, the border portion 3 is formed to match the pattern on the picture paper 6.

That is, a edging material such as sol-formed unsaturated polyester is placed in a tube, for example, an inverted conical tube used for squeezing cream used when making cakes, and the edging material is squeezed out along the pattern of the picture paper 6 to form the edging portion. 3 onto the box-shaped film 8 in a raised shape (specifically, 2 to 3 mm).

Further, since the picture paper 6 becomes unnecessary upon completion of the edging work, it is removed from under the box-shaped film 8.

(3) As shown in FIG. 5, when the border 3 becomes gelled, the area 12 surrounded by the border
A colored layer 4 is formed by filling the colored synthetic resin material with a fluid color using a dropper, pipette, etc. until it reaches the same height as the border 3.

It should be noted that the colored synthetic resin material shrinks to some extent when cured, and the surface of the resin material exhibits a downwardly concave shape between the border portions 3.

(4) As shown in FIG. 6, once the colored layer 4 has hardened into a jelly-like state, a transparent synthetic resin material is poured over the pattern layer 1 consisting of the border 3 and the colored layer 4, and a box-shaped film is formed. A flat reinforcing layer 2 is formed on the entire inner wall of the cell 8.

Note that the thickness of the reinforcing layer 2 is approximately 1 mm.

(5) As shown in FIG. 7, when the reinforcing layer 2 is completely cured, the box-shaped film 8 is peeled off from the pattern layer 1 and the reinforcing layer 2 to obtain the desired synthetic resin decorative board 10.

This decorative board 10 has a pattern layer 1 made of a box-like film 8.
Since the pattern layer 1 is formed on the surface of There is no shine or the color of the colored layer 4 becomes unclear.

As mentioned above, this decorative board is flat on both the front and back sides, and the design is clearly displayed, and the same type of synthetic resin is used for the design layer and the reinforcing layer to ensure the adhesion of both layers. Because it is a decorative item, it is best placed in a frame as a decorative figurine, or used as an alternative to stained glass for window displays and indoor decorations.

In addition, since the entire product is made of synthetic resin, processing such as cutting, punching, and gluing is easy, and desired processing can be easily performed when used for jewelry boxes, umbrellas for desk lamps, and the like.
