JP 2011-162042 A

  In the decorative panel as described above, there is a desire to switch between a metallic effect and a light effect depending on the lightness and darkness of the passenger compartment. For example, in order to be able to switch between these two effects by turning on and off the light to the decorative panel, it is necessary that the glitter pigment contained in the decorative panel can transmit light. Such a luster pigment can be obtained by pulverizing an extremely thin metal film set so as to transmit light. However, if the metal film is thin, the pulverized metal film is destroyed during pulverization or kneading with the molten resin after pulverization. Therefore, in the conventional decorative panel, it has been difficult to combine a metallic effect and a light effect.

  The present invention is intended to solve such a problem, and an object thereof is to provide a decorative panel for a vehicle capable of producing a metallic effect and a light effect.

  The present invention is for achieving the above-described object and is configured as follows.

  The decorative panel of the present invention is a decorative panel for producing light in a vehicle. This decorative panel is formed of a resin material that can transmit light and a luster pigment kneaded in the resin material. The glitter pigment is obtained by pulverizing a laminate comprising a transparent film and a metal film formed on the transparent film. The transparent film is set to a thickness that can maintain the shape of the pulverized metal film. The metal film is set to a thickness that allows light to pass through.

  In the present invention, the metal film for obtaining the glitter pigment is set to a thickness capable of transmitting light, and then the metal film is formed into a transparent film set to a thickness capable of maintaining the shape of the metal film after pulverization. It is formed against. Therefore, even though the metal film has a very thin thickness capable of transmitting light, the laminate including the metal film when producing the glitter pigment is pulverized, and the molten resin of the pulverized laminate is used. In the kneading and the like, the metal film pulverized with the pulverization of the laminate is not broken. Therefore, the pulverized metal film having a thickness capable of transmitting light can be reliably kneaded into the resin material forming the decorative panel. As a result, when the decorative panel of the present invention is not exposed to light, a metallic effect can be produced by the glittering pigment, and when the decorative panel is irradiated with light, the light is reflected by the glitter. Light can be produced by passing through the pigment.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. A high-luminance ornament 5 is attached to the lower part of the grab box 3 on the instrument panel 1 on the passenger seat side shown in FIG. The lower edge of the ornament 5 is trimmed by the decorative panel 20. The ornament 5 and the decorative panel 20 are both so-called decorative panels that decorate the passenger compartment. Here, only the panel that borders the ornament 5 is used as the decorative panel.

  As shown in FIGS. 2 to 4, the decorative panel 20 includes a back surface portion 22 disposed on the back surface side of the ornament 5, and an overhang portion 24 that protrudes from the back surface portion 22 toward the vehicle compartment. A front surface 24 a of the overhang portion 24 is exposed to the vehicle compartment along the lower edge of the ornament 5. Note that the inside of the overhang portion 24 is a continuous space between both side portions of the overhang portion 24. Both side portions of the overhanging portion 24 are covered with cover members C provided individually on both side portions of the decorative panel 20.

  The decorative panel 20 constitutes a part of the lighting device 10 shown in FIGS. In addition to the decorative panel 20, the illuminating device 10 is arranged at one end of the light guide 30 and a light guide 30 that is incorporated in the extension 24 and extends between both sides of the extension 24. For example, a light emitting source 40 such as a light emitting diode (LED) that makes light incident on the light guide 30 and a light shielding cover 50 that covers the light guide 30 from the back side are configured. These members 20, 30, 40 and 50 are fixed to the cover member C, for example, and are integrated. In the illuminating device 10, when the light source 40 emits light, the entire light guide 30 enters a light emitting state. Thereby, light is irradiated toward the front surface 24 a of the overhanging portion 24 of the decorative panel 20.

  As shown in FIG. 5, the decorative panel 20 is made of a resin material J capable of transmitting light and a luster pigment G kneaded in the resin material J, and is molded into a predetermined shape by, for example, injection molding. Yes. The glitter pigment G has a glitter and can transmit light. The diameter of the glitter pigment G is 10 to 180 mμ, and more preferably 10 to 40 mμ. Further, the glitter pigment G is contained by 0.3 to 0.5% by weight with respect to the total weight of the decorative panel 20 including the glitter pigment G itself and the resin material J.

  The glitter pigment G is obtained by pulverizing the laminate 70 shown in FIG. In forming the laminated body 70, first, the transparent film 80 is formed on the surface of a substrate (not shown). Then, a metal film 90 is formed on the surface of the transparent film 80. Further, a transparent film 80 is formed on the surface of the metal film 90. In this laminated body 70, both transparent films 80 are the base films of the metal film 90. In forming the metal film 90, a vacuum vapor deposition method, a reactive vapor deposition method, an ion plating method, a reactive ion plating method, a sputtering method, a reactive sputtering method, or the like is used.

  The transparent film 80 of the stacked body 70 is made of, for example, silicon resin. Further, the transparent film 80 is set to a thickness that can maintain the shape of the metal film 90 that is pulverized when the laminate 70 is pulverized. The specific thickness of the transparent film 80 is 5 to 500 mμ. The material of the transparent film 80 is not limited to silicon resin.

  The metal film 90 of the stacked body 70 is made of, for example, aluminum. The metal film 90 is set to a thickness that allows light to pass through. The specific thickness of the metal film 90 is 5 to 100 mμ. The material of the metal film 90 is not limited to aluminum.

  In the production of a conventional bright pigment (for example, aluminum flakes), only the metal film is formed without providing the transparent film 80 shown in FIG. 6, and the metal film is pulverized. For this reason, the metal film cannot be made thinner than a predetermined thickness (about 1 μm) due to the restriction of preventing the metal film from being broken during the pulverization of the metal film. As a result, the glitter pigment transmits light. It was extremely difficult to make it possible.

  On the other hand, in the present invention, the metal film 90 for obtaining the luster pigment G is set to a thickness capable of transmitting light, and the metal film 90 has the shape of the metal film 90 after pulverization. It is formed with respect to the transparent film 80 set to a thickness that can be held. From this fact, the laminated body 70 including the metal film 90 when the glittering pigment G is manufactured, or the pulverized laminated film, although the metal film 90 has a very thin thickness capable of transmitting light. During kneading of the body 70 with the molten resin, the pulverized metal film 90 is not destroyed along with the pulverization of the laminated body 70.

  Therefore, in the present invention, the pulverized product of the metal film 90 having a thickness capable of transmitting light can be reliably kneaded with the resin material J forming the decorative panel 20. As a result, in the decorative panel 20, when the light emitting source 40 of the lighting device 10 is not caused to emit light, the glittering pigment G can produce a metallic effect, and when the light emitting source 40 of the lighting device 10 is caused to emit light. The light emitted from the light guide 30 can be transmitted through the glitter pigment G to produce light.

  The best mode for carrying out the present invention has been described above with reference to the drawings. However, this embodiment can be easily changed or modified without departing from the gist of the present invention. ) To (3) will be described next.

  (1) The lighting device 10 including the decorative panel 20 includes a portion (for example, a center cluster) other than that shown in FIG. 1 in the instrument panel 1, vehicle interior such as a door trim, a center console, an overhead console, and a bumper. It may be incorporated in an appropriate location on the exterior of the vehicle to form a border or various designs (for example, a line pattern).

  (2) The illuminating device 10 may change the light guide 30 and the light emission source 40 shown in FIG. 4 as follows. That is, a rod-shaped light source that extends between both side portions of the overhanging portion 24 may be disposed inside the overhanging portion 24 of the decorative panel 20. In addition, a plurality of point light sources may be arranged at arbitrary intervals between both side portions of the overhanging portion 24 inside the overhanging portion 24 of the decorative panel 20.

  (3) In the laminated body 70, the transparent film 80 serving as the base film of the metal film 90 may be formed on only one of the front and back surfaces of the metal film 90.
