Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a top material made of a sheet material that is fixed to the top surface of a ski for protection and decoration, and to a method for manufacturing the same.

[Conventional technology]

As is well known, a sheet-like upper material is fixed to the upper surface of a ski for protection and decoration of the upper surface of the ski. As this top material, a sheet material containing a pigment in acrylonitrile-butadiene-styrene resin (hereinafter abbreviated as ABS resin) is used.

FIG. 4 shows an enlarged view of the main parts of a conventional general ski, and 1 indicates the ski.

An ABS resin sheet 3 colored with a pigment is fixed to the upper surface 2 of the ski 1 as an upper surface material. This ABS
A design ink 4 is painted on the resin sheet 3, and a transparent paint 5 is applied on the upper layer of the design ink 4 to protect the design ink 4 and to give a beautiful finish. I am finishing it.

However, the upper surface material using the ABS resin sheet 3 colored with the pigment mentioned above has a problem in that it cannot obtain the vividness compared to the one colored with dye because it is colored with the pigment. .

Therefore, instead of fine dyes, we used fluorescent dyes. When the ABS resin sheet 3 is colored with a general dye, the solvent in the design ink 4 causes the dye in the ABS resin sheet 3 to melt into the design ink 4 (hereinafter abbreviated as bleed). )
, there is a problem that the original color of the design ink 4 cannot be expressed.

This will be explained based on FIG. Figure 5 is A of Figure 4.
A case is shown in which the sheet 3 made of BS resin is colored with dye. A solvent is mixed in the design ink 4, and the solvent melts the ABS resin sheet 3 to some extent, causing the dye 6 in the ABS resin sheet 3 to spread as shown by the arrow. It gets mixed into the design ink 4 until the design ink 4 finishes drying. Therefore, if AB
If the color of the S resin sheet 3 is fluorescent red and the design ink 4 is white, then the design ink 4
The actual display color is close to pink, and the desired white color cannot be displayed. Incidentally, the above-mentioned bleeding is a phenomenon that occurs even after the design ink 4 is once cured. Therefore, in the past, in order to provide brightness, fluorescent dyes or dye-containing paints were painted on general ABS resin sheets, and in order to avoid bleeding from the paint.
After applying transparent paint, design ink was applied. This will be explained based on Figure 6. An ABS resin sheet 7 is fixed to the upper surface 2 of the ski 1. This sheet 7 made of ABS resin is usually used when the paint film is scratched, because if there is a significant difference in hue from the fluorescent paint 9, it will give a strange feeling, so the sheet 7 should not be colored.
adopt. Fluorescent paint 9 is applied on the ABS resin sheet 7.
In order to improve the color development, a normally white paint 8 is applied, and a fluorescent paint 9 is applied thereon. Then, in order to prevent the same problem as explained in FIG. 5 from occurring, a transparent paint 10 to prevent bleeding is applied, a silk work is applied to the design ink 11, and a final transparent paint 12 is applied to complete the process. [Problem to be solved by the invention] However, as mentioned above, when trying to solve the problem by painting, there are three layers of painting process in the lower layer of the design ink l1,
The problem is that it takes a lot of man-hours. Therefore, labor costs. This resulted in an increase in material costs and an increase in manufacturing costs.

In addition, the brittleness of the surface of the coating film caused by painting sometimes became a problem. Furthermore, the painting process is often prone to defects and requires many man-hours for corrections.

However, even the transparent paint 10 that prevents bleeding cannot completely prevent bleeding due to the amount of solvent in it and the amount of solvent in the design ink 11. The present invention was made to solve these conventional problems, and its purpose is to reduce manufacturing costs, eliminate rework of defects caused by painting, shorten process period, and The object of the present invention is to provide a ski top material that can express the colors desired by the intended user and a method for manufacturing the same. [Means for Solving the Problem] The ski upper material according to claim 1 comprises a lower layer made of a dye-containing acrylonitrile-butadiene-styrene resin sheet, and an upper layer made of a transparent acrylonitrile-butadiene-styrene resin sheet.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a ski top material 20 according to an embodiment of the present invention.

This ski upper material 20 is made of ABS containing fluorescent dye.
It is formed by integrally laminating a lower layer sheet 21 made of a resin sheet and an upper layer sheet 22 made of an ABS resin sheet containing no dye.

The ski upper surface material 20 configured in this way has, for example, a second
As shown in the figure, the ski 30 is fixed on the upper surface 31, and a design ink 23 is applied thereon, and a transparent paint 24 is applied thereon to protect the design ink 23 and to give a beautiful finish. give

According to the ski upper material 20 as described above, the lower layer sheet 21 made of an ABS resin sheet containing a dye is different from the upper layer sheet 21 made of an ABS resin sheet containing no dye.
Since it is integrally protected by 2, it never comes into contact with the solvent of the design ink 23 applied to the upper surface.

Therefore, bleeding due to the solvent contained in the design ink 23 does not occur. Therefore, it becomes possible to arbitrarily select a desired color for the design ink 23 as well. Furthermore, there is no need to apply multiple coats, which reduces manufacturing costs.

In the above embodiment, both the lower sheet 21 and the upper sheet 22 are made of ABS resin, but the present invention is not limited to this. For example, the lower sheet 21 and the upper sheet Both sheets 22 and 22 may be made of polyurethane resin, or the lower sheet 21 may be made of ABS resin and the upper sheet 22 may be made of polyurethane resin. In particular, polyurethane resin has good transparency, so if the upper sheet 22 is made of polyurethane resin, the designs and patterns colored with dyes can be made more clearly than those made of ABS resin. It becomes possible to express it. FIG. 3 shows the manufacturing principle of the method for manufacturing a ski top material according to the present invention.

ABS resin 42 containing dye and ABS resin containing no dye are produced through orifices 41 of two extrusion molding machines 40, 40.
The resin 43 is molded into a sheet in a molten state and sent out, and is compressed by pressing rollers 44 and then wound up.

Then, the coil 45 is cut into a desired length and used as the ski upper material 20.

According to the above embodiment, two ABS extruded at the same time
Since the resins 42 and 43 are integrally pressed by the pressure rollers 44, 44, a desired laminate can be obtained without using adhesive. In the method for manufacturing the ski upper material described above, a case has been described in which the ABS resin 42 containing a dye and the ABS resin 43 not containing a dye are molded into a sheet shape in a molten state. For example, both of the ABS resins 42 and 43 may be replaced with a polyurethane resin, or only the ABS resin 43 that does not contain dye may be replaced with a polyurethane resin.
