BEST MODE FOR CARRYING OUT THE INVENTION
According to the present invention, the plated grid design component has a grid having a grid front face (design front face) facing a person and a grid side face (design side face) connected to the grid front face. The lattice can function as a design part. A metal plating layer is laminated so as to be thicker on the front side of the grid than on the side faces of the grid. Further, a smoke clear layer is laminated on the metal plating layer. For this reason, the light reflection on the grating side surface of the grating is suppressed, and although the grating side surface has a dark-colored transparency, the grating front surface of the grating reflects light intensively. Therefore, it is possible to intensively illuminate the front surface of the lattice that directly faces the person, with the lattice side that gives dark color transparency as a background. Therefore, the three-dimensional appearance of the grid of the plated grid design part is further enhanced.
[0011]
The term “plated grid design part” means a design part having a grid at least in part and having a resin as a base material. The lattice means a thin wall extending in a predetermined direction. The direction in which the lattice extends is not particularly limited, and may be a form extending only in the horizontal direction, a form extending only in the vertical direction, a form in which a vertically extending part intersects with a part extending in the horizontal direction, or a form extending in an oblique direction. But it's fine. The thickness of the wall forming the lattice is not particularly limited.
[0012]
A grill can be exemplified as a typical plated grid design part. Grill means a part having a lattice at least in part. As the grill, a makeup grill generally arranged in a public place can be adopted. As a typical grill, a radiator grill located at the front of the vehicle and covering the radiator can be exemplified. Further, examples of the grill include a grill for a deodorizing device, a grill for an air conditioner, a grill for an audio device such as a tape recorder and a radio cassette player, a grill for an electric / electronic device, and a grill for building parts. The resin serving as the base material constituting the plated grid design part is not particularly limited, and a thermoplastic resin or a thermosetting resin can be employed. Specifically, ABS resin, acrylic resin, polycarbonate, polypropylene, vinyl chloride, polyurethane and the like can be exemplified.
[0013]
The grid of a plated grid design component such as a grill has a grid front face that faces the person and is easily visible to the naked eye of a person, and a grid side face connected to the grid front face. The lattice front can function as a design front. The lattice side can function as a design side, and extends in a direction crossing the lattice front.
[0014]
According to the present invention, in the grid, the metal plating layer is laminated so as to be thicker on the front side of the grid than on the side faces of the grid. The case where the metal plating layer is not laminated on the side surface of the lattice is also included. Assuming that the average thickness of the metal plating layer laminated on the lattice front surface is 100, the average thickness of the metal plating layer laminated on the lattice side surface can be, for example, 50 or less, 30 or less, 20 or less, 10 or less. Can be 0.
[0015]
The average thickness of the metal plating layer laminated on the front surface of the lattice can be about 10 to 100 μm, particularly about 10 to 30 μm, but is not limited thereto.
[0016]
Any metal plating layer can be used as long as it can exhibit metallic luster, and examples thereof include a chromium plating layer, a nickel plating layer, a copper plating layer, a zinc plating layer, a gold plating layer, and a silver plating layer. Examples of the metal plating layer include a layer formed by electroplating and a layer formed by electroless plating.
[0017]
When applying a metal plating layer by applying an electroplating process to a resin-based grid design component main body, perform the electroplating directly because the grid design component body is a resin base material. Can not. For this reason, as a pretreatment, it is preferable to laminate a base plating layer made of a metal as a base material on the resin-made grid design component body by electroless plating or the like, thereby making the resin-made grid design component body conductive. The base plating layer may be a single layer or a plurality of layers. In the case of forming the base plating layer, a layer of the base plating layer which is directly laminated on the resin-made grid design component body can be an electroless plating layer.
[0018]
Further, according to the present invention, the smoke clear layer is laminated on the metal plating layer laminated on the lattice. In this case, the smoke clear layer may be directly laminated on the metal plating layer, or may be laminated indirectly via another transparent layer. The smoke clear layer means a dark transparent layer in which a pigment is mixed in a transparent resin. An example of the transparent resin is an acrylic resin. As the pigment, one or more of a black pigment, a red pigment, and a blue pigment can be employed. In obtaining the smoke clear layer, the ratio of the pigment to the entire smoke clear layer can be 8% or less by weight. In particular, 5% or less, 3% or less, and 1% or less can be exemplified depending on the type of the pigment, the use of the plated grid design part, and the like.
[0019]
The average thickness of the smoke clear layer laminated on the front surface of the lattice can be about 10 to 50 μm, particularly about 20 to 30 μm, but is not limited thereto.

【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0021]
This embodiment is a case where the present invention is applied to a radiator grill 1 that covers a radiator mounted on a vehicle. FIG. 1 is an external view of the radiator grill viewed from diagonally above. FIG. 2 is a schematic cross-sectional view of a main part showing the stacking order of the plating process. Since the radiator grille 1 is mounted on the front part of the vehicle, it gives a design effect to the front part of the vehicle. A grid 25 is provided on almost the entire area of the radiator grill main body 2 (grid design component main body) constituting the radiator grill 1. As shown in FIG. 1, the lattice 25 has a number of vertical lattice portions 20 facing each other and a number of horizontal lattice portions 21 intersecting with the vertical lattice portions 20 and facing each other. Note that the vertical lattice portions 20 are arranged in parallel with each other. The horizontal lattice portions 21 are arranged in parallel with each other.
[0022]
The lattice 25 can function as a design part because it can be easily touched by human eyes. The lattice 25 has a lattice front surface 30 (design front surface) that is easily visible to the naked eye of a person because it directly faces a person, and a lattice side surface 33 (design side surface) connected to the lattice front surface 30. The lattice side surface 33 extends in a direction intersecting with the lattice front surface 30 and is not easily visually recognized by human eyes. The base material constituting the radiator grill main body 2 is made of resin (for example, ABS resin).
[0023]
In this embodiment, the radiator grill main body 2 has a base plating layer 2c laminated thereon. The metal plating layer 5 is laminated on the base plating layer 2c of the radiator grill main body 2. The metal plating layer 5 is laminated so as to be thicker on the lattice front surface 30 than on the lattice side surface 33. A chromium plating layer is employed as the metal plating layer 5. Assuming that the average thickness of the metal plating layer 5 laminated on the lattice front surface 30 is 100, the average thickness of the metal plating layer 5 laminated on the lattice side surface 33 is about 10 to 50 μm. The average thickness of the metal plating layer 5 laminated on the lattice front surface 30 is about 0.05 to 2.0 μm, particularly about 0.1 to 1.2 μm.
[0024]
Further, on the metal plating layer 5, a smoke clear layer 6 for giving a black transparent feeling is laminated by spray coating or the like. The smoke clear layer 6 means a dark transparent layer obtained by mixing a pigment with a transparent resin. Acrylic resin is used as the transparent resin. A black pigment (for example, carbon black) is used as the pigment. In the smoke clear layer 6, the ratio of the pigment to the entire smoke clear layer 6 is appropriately selected, and is, for example, about 5 to 20% by weight. The average thickness of the smoke clear layer 6 on the lattice front surface 30 is appropriately selected, and is, for example, about 15 to 30 μm.
[0025]
In manufacturing the radiator grill 1 according to the present embodiment, first, a resin radiator grill main body 2 having a grid 25 having a grid front surface 30 facing a person and a grid side surface 33 connected to the grid front surface 30 is used. . Since the radiator grill main body 2 is made of resin, it is not possible to directly perform the electroplating process. For this reason, as a pretreatment, a metal base plating layer 2c is laminated on the resin radiator grill main body 2 to make the resin radiator grill main body 2 conductive. The base plating layer 2c may be a single layer or a plurality of layers. Although the resin constituting the radiator grill main body 2 and the metal plating layer 5 have considerably different coefficients of thermal expansion and thermal contraction, a plurality of layers make it easier to absorb differences in thermal expansion and thermal contraction. When the base plating layer 2c has a plurality of layers, the layer directly laminated on the resin radiator grill main body 2 can be an electroless plating layer, and the remaining layers can be electroplating layers.
[0026]
Then, an electroplating process is performed on the radiator grill main body 2 on which the base plating layer 2c is laminated. In this case, the radiator grill main body 2 is immersed in the plating solution in the plating tank. Then, as schematically shown in FIG. 3, the grid front surface 30 of the radiator grill main body 2 faces the anode 100 in the plating solution, and the radiator grill main body 2 is electrically connected to the cathode 200. In this state, electricity is supplied between the cathode 200 and the anode 100 to perform an electroplating process. If the electroplating is performed in this manner, the lattice front surface 30 of the radiator grill main body 2 directly facing the anode 100 has a high lamination efficiency of the metal plating layer 5, but directly faces the anode 100. The lamination efficiency of the metal plating layer 5 is low on the lattice side 33 that is not formed. Therefore, the metal plating layer 5 is laminated so as to be thicker on the lattice front surface 30 than on the lattice side surface 33.
[0027]
In this embodiment, the smoke clear layer 6 is further laminated on the metal plating layer 5 by a coating method such as spray coating. Through the above-described steps, the radiator grill 1 having a metallic luster while using a resin as a base material is manufactured.
[0028]
As described above, in the radiator grill 1 according to the present embodiment, the metal plating layer 5 is laminated so as to be thicker on the lattice front surface 30 than on the lattice side surfaces 33 of the lattice 25. Further, a smoke clear layer 6 which is a black transparent layer is laminated on the metal plating layer 5.
[0029]
For this reason, as schematically shown in FIGS. 4 and 5, light reflection on the grating side surface 33 of the grating 25 of the radiator grill 1 is suppressed for a person located in front of the radiator grill 1, and the grating side surface 33 of the grating is It is visually perceived by the human eye in a dark color (black color). On the other hand, since the grating front surface 30 of the grating 25 reflects light with high light reflectance, the grating front surface 30 is visually perceived by the human eye as if concentratedly glowing. For this reason, the three-dimensional appearance of the lattice 25 is further enhanced as compared with the conventional radiator grill.
[0030]
That is, when the grid 25 of the radiator grill 1 is viewed from the front, the grid front surface 30 of the grid 25 of the radiator grill 1 is shining and visible, and the grid side surfaces 33 where the metal plating layer 5 is little attached are darker (black) due to the smoke color. It is visually recognized. For this reason, the three-dimensional appearance of the lattice 25 is further enhanced as compared with the conventional radiator grill.
[0031]

In addition, the present invention is not limited to only the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications without departing from the scope of the invention. The words and phrases described in the embodiments and examples can be described in each claim even if only a part. In some cases, the present invention can be applied to design parts (moulds, aluminum wheels, and the like) having no lattice, although this departs from the scope of the claims.

Representative plated design parts include emblems for vehicles and the like, marks for vehicles, grills such as radiator grills, moldings, aluminum wheels, and the like. This plated design component is made of resin as a base material, and has a design front face such as a grid front face facing a person and a design side face such as a grid side face connected to the design front face. Therefore, for a person located in front of the plated design part, light reflection on the front side of the design, such as the side of the lattice, is suppressed in the design portion, such as the lattice, and the side of the design, such as the side of the lattice, is visually recognized by a person in a dark color. On the other hand, among the design portions such as the lattice, the design front surface such as the lattice front surface directly facing the person reflects light with a high light reflectance, so that the person is visually recognized as intensively shining. . For this reason, the three-dimensional appearance of a design part such as a lattice of a plated design part such as a radiator grille is further enhanced as compared with a conventional plated design part. Therefore, although the base material is a resin, the metallic luster of the lattice is enhanced, and the design is improved.
