Description

  The present invention relates to a composite resin panel and a method for manufacturing the same, and more specifically, a three-dimensional gradation pattern that can exhibit a sufficient light shielding function or visibility control function and has a sense of depth due to the difference in color between the substrate and the band plate. The present invention relates to a composite resin panel having excellent design properties and excellent productivity, and a method for producing the same.

  Conventionally, it is generally known to use a resin panel in which the surface of a substrate is coated as an exterior material around a display screen of a television receiver or a personal computer. However, in this resin panel, since the surface pattern is formed by painting, a three-dimensional gradation pattern with a depth is not expressed and the design is low.

  Further, as a conventional method for producing a resin panel, a method for producing a resin panel by simultaneously extruding two different colors of resins has been proposed (see, for example, Patent Documents 1 and 2). Patent Documents 1 and 2 each include a resin panel that includes a substrate made of transparent resin and a plurality of strips made of opaque resin embedded in parallel in the substrate, and has a light shielding function or a visibility control function. It is disclosed.

  However, in the resin panels of Patent Documents 1 and 2, the substrate is made of a transparent resin, the plurality of strips are made of an opaque resin, and the edges of the plurality of strips are embedded without being exposed on the surface of the substrate. Therefore, the shading function or visibility control function by each strip is not sufficient, and when viewed from the surface of the substrate, the edge of each strip is a simple striped pattern, which also represents a three-dimensional gradation pattern with depth. The design was low.

The first embodiment exemplifies a form used as an outer frame of a television receiver (that is, an exterior material of a home appliance) as a “composite resin panel” according to the present invention. Moreover, in the present Example 2, the form used as a fence as a "composite resin panel" concerning the present invention is illustrated.

It is equipped with. The display unit main body 2 includes a display screen 4 a configured by the liquid crystal panel 4 and an outer frame 5 that covers the outer periphery of the display screen 4 a and supports the liquid crystal panel 4. As shown in FIG. 2, the outer frame 5 includes an outer frame body 7 (illustrated as a “decorative member” according to the present invention) and a flat plate-like composite resin attached to the front side of the outer frame body 7. And a panel 10. The outer frame body 7 is made of a black opaque acrylic resin to which carbon black is added as a black coloring material.

As shown in FIG. 3, the composite resin panel 10 includes a flat substrate 11 and a plurality of flat plates 11 (five in FIG. 3) provided on the substrate 11 so as to be inclined with respect to the plane of the substrate 11. The belt plate 12 is provided. The substrate 11 is made of a blue transparent acrylic resin (illustrated as “first resin” according to the present invention) obtained by adding ultramarine blue as a blue coloring material to a methyl methacrylate resin.
Each strip 12 is made of a white opaque acrylic resin (illustrated as “second resin” according to the present invention) in which titanium oxide is added as a white coloring material to a methyl methacrylate resin. ing. Further, the edge of each strip 12 is exposed on the surfaces on both sides of the substrate 11.

  The thickness t1 of the substrate 11 is about 2 mm. The inclination angle θ of each strip 12 with respect to the plane of the substrate 11 is about 40 degrees. The thickness t2 of each strip 12 is about 50 μm. Further, the adjacent end portions of the pair of adjacent strip plates 12 of the plurality of strip plates 12 are separated from each other in the plane direction of the substrate, and the separation interval s1 is about 1 mm.

  The composite resin panel 10 is formed by simultaneously extruding a blue transparent acrylic resin and a white opaque acrylic resin. Specifically, as shown in FIGS. 10 and 11, a blue transparent acrylic resin 51 a extruded from the first extruder 51 and a white opaque acrylic resin 52 a extruded from the second extruder 52 are placed in the mold 53. And the merged product 53a pushed out from the mold 53 is passed through a sizing die 54 and taken up by a known take-up device 55 (for example, a caterpillar take-up machine, etc.). The said composite resin panel 10 provided with the strip 12 will be obtained. The width of the passage opening of the sizing die is set to a value smaller than the width of the outlet of the mold (see FIG. 11).

(2) Operation of Television Receiver Next, the operation of the television receiver 1 having the above configuration will be described.
When a user who uses the television receiver 1 sees the outer frame 5 from the front (indicated by a broken line arrow in FIG. 3), in the composite resin panel 10, sufficient visibility control is performed by a plurality of inclined strips 12. The function is exhibited and the outer frame body 7 is hidden from the user's view. Then, due to the overlap between the blue transparent substrate 11 and the inclined white opaque strips 12, the amount of the substrate 11 on the view side of the strip 12 is increased for each strip 12 when the substrate 11 is viewed from the surface. A gradation pattern m1 (see FIGS. 3 and 4) that gradually increases toward P is displayed.

  Further, as shown in FIG. 4A, when the composite resin panel 10 is viewed straight from the front, the black opaque outer frame body 7 is formed through a gap s1 formed between a pair of adjacent strips 12. In addition, a black stripe pattern m2 is displayed as a surface pattern in addition to the gradation pattern m1. On the other hand, as shown in FIG. 4B, when the composite resin panel 10 is looked down from the front or slightly above, the gap between the strips 12 disappears and only the gradation pattern m1 is displayed as the surface pattern.

(3) Effects of Example As described above, according to the composite resin panel 10 of this example, the white opaque strip 12 is provided on the substrate 11 so that the edge thereof is exposed on the surface of the blue transparent substrate 11. Therefore, by overlapping the blue transparent substrate 11 and the white opaque strip 12, it is possible to exert a sufficient visibility control function when the substrate 11 is viewed from the surface, and the depth sensation due to the difference in color between the substrate 11 and the strip 12. The three-dimensional and clear gradation pattern m1 is expressed and has excellent design. In particular, in the present embodiment, a plurality of strip plates 12 are provided on the substrate 11 so as to be inclined in the plane of the substrate 11 and in parallel with each other. It can be expressed and the design can be further enhanced.

  In this embodiment, since the black opaque outer frame body 7 is laminated on the surface of the substrate 11, a gap formed between a pair of adjacent strips 12 depending on the angle when viewing the composite resin panel 10. The outer frame body 7 can be seen through and a black stripe pattern m2 is displayed as a surface pattern in addition to the gradation pattern m1. Therefore, the design of the surface pattern can be further improved.

  In this embodiment, since the blue transparent acrylic resin and the white opaque acrylic resin are simultaneously extruded to obtain the composite resin panel 10, the productivity can be further increased.

  In this embodiment, since the acrylic resin is used as the substrate 11 and each strip 12, the composite resin panel 10 having excellent weather resistance as the outer frame 5 of the television receiver 1 can be obtained.

  In the embodiment, since the thickness t1 of the substrate 11 is about 2 mm and the thickness t2 of each strip 12 is about 50 μm, a clearer gradation pattern can be expressed while suppressing the amount of resin used.

  Further, in this embodiment, the adjacent end portions of the pair of adjacent strip plates 12 of the plurality of strip plates 12 are separated in the plane direction of the substrate 11, and the separation interval s1 is about 1 mm. By separating the end portions of the strips, the light shielding effect can be suppressed and the visual effect can be further enhanced.

  Furthermore, in this embodiment, since the inclination angle θ of the band plate 12 with respect to the plane of the substrate 11 is about 40 degrees, each band plate 12 can exhibit a more sufficient visibility control function.

  In the present embodiment, the blue transparent acrylic resin 51 a extruded from the first extruder 51 and the white opaque acrylic resin extruded from the second extruder 52 are merged in the mold 53. Since the merged material 53a to be extruded is allowed to pass through the sizing die 54, the odd-shaped composite resin panel 10 can be obtained.

On the other hand, as shown in FIG. 6B, when the fence 1 ′, that is, the composite resin panel 10 ′ is looked up from the front or slightly below, a large amount of light is taken in through gaps formed between the strips 12. At the same time, the other side of the fence 1 'can be seen.

(3) Effects of Example As described above, according to the composite resin panel 10 ′ of the present example, the adjacent end portions of a pair of adjacent strip plates 12 ′ of the plurality of strip plates 12 ′ are arranged on the substrate 11. Since they are overlapped in the plane direction and the overlap interval s2 is set to about 0.1 mm, the visible effect can be suppressed and the light shielding effect can be further enhanced by the overlap of the end portions of the strips 12 '.

  Note that the present invention is not limited to the first and second embodiments, and various modifications can be made within the scope of the present invention depending on the purpose and application. That is, in the first embodiment, the composite resin panel 10 in which the adjacent end portions of the pair of adjacent strips 12 are separated by a predetermined separation interval s1 in the plane direction of the substrate 11 is exemplified. For example, as shown in FIG. 5, the adjacent end portions of a pair of adjacent strips 12 'are adjacent to each other at a predetermined overlap interval s2 (for example, about 0.1 mm) in the plane direction of the substrate 11'. It is good also as the composite resin panel 10 'which overlaps. In this case, in addition to the effects and effects similar to those of the first embodiment, when the composite resin panel 10 is viewed straight from the front as shown in FIG. Since there is no gap, only the gradation pattern m1 is displayed as the surface pattern. On the other hand, as shown in FIG. 6B, when the composite resin panel 10 is looked up slightly from the front, it is formed between the strips 12. A black opaque outer frame body 7 is seen through the gap, and a black stripe pattern m2 is displayed as a surface pattern in addition to the gradation pattern m1.

  Moreover, in the said Example 1 and 2, although the composite resin panel 10 which provided the some strip 12 in the board | substrate 11 was illustrated, it is not limited to this, For example, as shown in FIG. A composite resin panel 30 provided with two strips 32 may be used. Even in this case, the overlapping of the colored transparent substrate 31 and the colored opaque strip 32 allows the substrate 31 to exhibit a sufficient light shielding function or visibility control function when viewed from the surface, and has a three-dimensional depth. A clear gradation pattern m1 is expressed and the design is excellent.

  Moreover, in the said Example 1 and 2, although the form which provides a strip | belt board over the substantially full length of the thickness direction of a board | substrate was illustrated, it is not limited to this, For example, as shown in FIG. A band plate 42 is provided on one surface side 41a in the direction, and the other surface side 41b in the thickness direction of the base material 41 is guided to guide light from a light source (for example, a light emitting diode) provided at the side edge of the panel. It is good also as the composite resin panel 40 used as an optical part. Thereby, a composite resin panel can be used conveniently as an illumination member. In this case, it is preferable to provide the light shielding layer 43 on the surface of the other surface side 41b used as the light guide. This is because the illumination effect can be further enhanced.

  Furthermore, in the said Example 1, although the composite resin panel 10 formed by laminating | stacking the black opaque outer frame main body 7 (decorative member) on the surface of the board | substrate 11 was illustrated, it is not limited to this, On the surface of the board | substrate 11 It is good also as the composite resin panel 10 in which a decorating member is not laminated | stacked.

  As the composite resin panel of the reference example, for example, as shown in FIG. 9, a first substrate 21 made of a colored transparent first resin and an inclined surface that abuts on an inclined surface 21 a formed on the first substrate 21. A composite resin panel 20 having a surface 22a and a second substrate 22 made of an opaque or colored transparent second resin can be given. Accordingly, a sufficient light shielding function or visibility control function can be exhibited by the first and second substrates 21 and 22. Further, when the first substrate is viewed from the plane due to the overlap between the colored transparent first substrate and the opaque or colored transparent second substrate, the thickness of the first substrate 21 increases gradually in the direction P. A gradation pattern m1 is displayed. Therefore, the design property of the surface pattern can be enhanced. Furthermore, since it can shape | mold by extrusion molding etc., it is excellent in productivity, without requiring a complicated coating operation like the past. As the first resin and the second resin, for example, the first embodiment described above. The configurations of the first resin and the second resin of the composite resin panel can be applied.

  In the reference example, the second resin is preferably an opaque resin. In addition, the first and second substrates 21 and 22 are right triangles having the same vertical cross section, and the inclined angles of the inclined surfaces 21a and 22a of the first and second substrates 21 and 22 with respect to the planes of the substrates 21 and 22 are, respectively. It is preferable that S is 1 to 20 degrees (preferably 1 to 10 degrees, particularly 2 to 4 degrees). This is because when the first substrate 21 is viewed from the surface, a clear gradation pattern is displayed, and the design of the surface pattern can be further enhanced.
