Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above-described decorative member, after the reinforcing layer is laminated on the back surface of the punching plate by insert molding, a paint is applied to the surface of the punching plate. Therefore, when the thickness of the coating layer formed by painting is thin, a step is likely to occur around the through holes provided in the punching plate. Further, when the resin composition for forming the reinforcing layer leaks out to the surface of the punching plate through the through holes, the edge of the through hole may become indistinguishable. As a result, there is a problem that characters, patterns, etc. formed by the through holes become difficult to recognize.

[0005] One aspect of the present disclosure aims to provide a wood-grain decorative molded article having a structure in which characters, patterns, etc. are easily recognizable.

Means for Solving the Problems

[0006] One aspect of the present disclosure is a wood grain decorative molded product comprising a veneer, a transparent layer, a through-hole, and a base material. The veneer has a front surface and a back surface. The transparent layer is laminated on the front surface of the veneer and transmits light. The through-hole is provided so as to penetrate the veneer and is covered by the transparent layer. The base material is laminated on the back surface of the veneer so as to fill the through-hole and transmits light. The surface of the base material in contact with the transparent layer within the through-hole is flush with the front surface of the veneer.

[0007] In this configuration, a permeable layer is provided on the surface of the veneer to cover the penetration, and the base material is filled into the penetration. This prevents the formation of steps in the permeable layer near the penetration and prevents the base material from seeping out onto the veneer surface near the penetration. Therefore, in decorative molded products with wood grain, it becomes easier to recognize letters, patterns, etc., formed by the penetration.

[0008] One aspect of this disclosure may further include a reinforcing layer laminated between the veneer and the substrate to reinforce the veneer. The penetration portion may be provided so as to further penetrate the reinforcing layer. In such a configuration, the veneer, which is formed by thinly slicing wood, is reinforced by the reinforcing layer. For this reason, for example, if the reinforcing layer is laminated to the veneer before it is integrated with the substrate, damage to the veneer before integration with the substrate can be suppressed.

[0009] One aspect of this disclosure may further include a backing layer laminated between the reinforcing layer and the substrate to reinforce the reinforcing layer. The penetration portion may be provided so as to further penetrate the backing layer. In such a configuration, the reinforcing layer is constrained by the backing layer, so that deformation of the veneer on which the reinforcing layer is laminated is suppressed. For this reason, for example, if the reinforcing layer and the backing layer are laminated to the veneer before integration with the substrate, shrinkage of the veneer on which the reinforcing layer and the backing layer are laminated before integration with the substrate is less likely to occur, and changes in shape and dimensions can be suppressed. Furthermore, because the backing layer is laminated on the side on which the substrate is laminated, it is possible to directly integrate the substrate and the backing layer without the use of an adhesive. As a result, a large anchoring effect is ensured, so that the veneer on which the reinforcing layer and the backing layer are laminated and the substrate can be firmly integrated with each other. Therefore, peeling and lifting of the veneer on which the reinforcing layer and the backing layer are laminated from the substrate can be suppressed.

[0010] In one aspect of this disclosure, the permeable layer may be formed by painting. With such a configuration, a permeable layer can be suitably formed on the surface of the veneer.

[0011] One aspect of the present disclosure is a method for manufacturing a wood grain decorative molded product comprising a veneer having a front surface and a back surface, a light-transmitting transparent layer, a reinforcing layer, a backing layer, and a light-transmitting substrate. The method for manufacturing a wood grain decorative molded product comprises: laminating a transparent layer onto the front surface of a veneer with a reinforcing layer bonded to its back surface; forming a sheet member by laminating a backing layer onto the reinforcing layer; processing the sheet member from the backing layer side to provide a penetration portion in the sheet member that penetrates the backing layer, the reinforcing layer, and the veneer and is covered by the transparent layer; and laminating a substrate into the backing layer of the sheet member by insert molding so that the substrate is filled into the penetration portion.

[0012] In this configuration, a sheet member is laminated in the order of a permeable layer, veneer, reinforcing layer, and backing layer. By processing the sheet member from the backing layer side, a perforation is created while leaving the permeable layer intact, and then the base material is insert-molded into the sheet member. As a result, the permeable layer is provided so as to cover the perforation, and the base material is filled into the perforation. Therefore, it is possible to suppress the formation of a step in the permeable layer near the perforation and the seepage of the base material near the perforation on the surface of the veneer. Consequently, in decorative molded products with wood grain, it is possible to make letters, patterns, etc., formed by the perforation easier to recognize. [Brief explanation of the drawing]

[0013] [Figure 1] This is a schematic cross-sectional view of a wood grain decorated molded product. [Figure 2] This is a flowchart showing the manufacturing method for wood grain decorated molded products. [Figure 3] Figures 3A to 3F schematically illustrate the manufacturing method of wood grain decorated molded products. [Modes for carrying out the invention]

[0014] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. [1. Structure] <Wood grain decorative molded product> The wood grain decorative molded product 100 shown in Figure 1 is a decorative molded product that has a wood grain design and is used, for example, as an interior part of an automobile. The wood grain decorative molded product 100 comprises a veneer 1, a reinforcing layer 2, a transparent layer 3, an adhesive layer 4, a backing layer 5, a base material 6, a top coat layer 7, and a through-hole 10.

[0015] The wood grain decorative molded product 100 is a molded product in which, with the upper side of Figure 1 as the top, the top coat layer 7, the transparent layer 3, the veneer 1, the reinforcing layer 2, the adhesive layer 4, the backing layer 5, and the base material 6 are laminated in that order from top to bottom. Note that Figure 1 is a schematic representation of the structure of the wood grain decorative molded product 100, and therefore the exact arrangement, shape, size ratios, etc. may differ from those of the actual wood grain decorative molded product. The same applies to Figure 3. In the following description, the member in which the transparent layer 3, veneer 1, reinforcing layer 2, adhesive layer 4, and backing layer 5 are laminated will be referred to as the sheet member 110.

[0016] The through-holes 10 that penetrate the backing layer 5, adhesive layer 4, reinforcing layer 2, and veneer 1 of the sheet member 110 are configured to transmit light, and when the wood grain decorative molded product 100 is viewed from the design surface 101 described later, letters, patterns, etc. are formed. The surface on which the top coat layer 7 of the wood grain decorative molded product 100 is formed is the design surface 101 on which the wood grain and letters, etc. are displayed, and the surface on which the base material 6 of the wood grain decorative molded product 100 is formed is the non-design surface 102. The wood grain decorative molded product 100 is configured so that letters, patterns, etc. can be displayed within the wood grain by, for example, illuminating the wood grain decorative molded product 100 from the non-design surface 102 side with a light source 200 and transmitting light through the through-holes 10. In this embodiment, the wood grain decorative molded product 100 is configured so that letters, patterns, etc. within the wood grain can be recognized even when there is no illumination of light from the light source 200.

[0017] <Veneer> The veneer 1 is used to decorate the wood grain decorative molded product 100. In this embodiment, the veneer 1 is formed by thinly slicing solid wood such as maple or walnut. The veneer 1 has a thickness in the range of approximately 0.05 mm or more and approximately 2.0 mm or less. In this embodiment, the wood grain decorative molded product 100 uses a veneer 1 having a thickness of approximately 0.2 mm or more and approximately 0.3 mm or less. The veneer 1 has a surface 11 that faces the design surface 101 and a back surface 12 that faces the non-design surface 102.

[0018] <Reinforcement layer> The reinforcing layer 2 is laminated on the back surface 12 of the veneer 1 to reinforce the easily cracked veneer 1. In this embodiment, the reinforcing layer 2 is formed of a non-woven fabric. Although not shown, the reinforcing layer 2 is laminated on the back surface 12 of the veneer 1 by being adhered with a melamine-urea-based adhesive. The melamine-urea-based adhesive has thermosetting properties and cures when heated. Therefore, when heat pressing, for example, is performed from the front surface 11 of the veneer 1 in a state where the reinforcing layer 2 is laminated on the back surface 12 of the veneer 1 via the above adhesive, the adhesive cures and the veneer 1 and the reinforcing layer 2 are integrated. Note that the reinforcing layer may be adhered to the veneer 1 with, for example, an epoxy-based or olefin-based adhesive. The reinforcing layer 2 has a thickness within a range of about 0.05 mm or more and about 1.0 mm or less. The wood grain decorative molded product 100 of this embodiment uses a reinforcing layer 2 having a thickness of about 0.1 mm.

[0019] <Transmission layer> The transmission layer 3 is laminated on the front surface 11 of the veneer 1 to protect the design surface 101 of the wood grain decorative molded product 100. In this embodiment, the transmission layer 3 is formed by coating the veneer 1 with a polyester paint and transmits light. The transmission layer 3 is preferably transparent. The transmission layer 3 is formed by successively coating a primer layer, a coloring layer, and a thick coating layer on the front surface 11 of the veneer 1.

[0020] <Adhesive layer> The adhesive layer 4 is laminated on the reinforcing layer 2 and is for adhering a backing layer 5 described later to the reinforcing layer 2. In this embodiment, the adhesive layer 4 is formed of an aqueous vinyl urethane-based adhesive.

[0021] <Backing layer> The backing layer 5 is laminated to the reinforcing layer 2 by bonding with the adhesive layer 4 described above, and its purpose is to reinforce the reinforcing layer 2 so that it does not tear, shrink, or deform. The backing layer 5 also functions as an anchoring layer when the base material 6, which will be laminated to the backing layer 5 later, is joined and integrated by insert molding. In this embodiment, the backing layer 5 is formed from a woven fabric using natural fibers. The backing layer 5 has a thickness in the range of approximately 0.05 mm or more and approximately 2.0 mm or less. In the wood grain decorated molded product 100 of this embodiment, a backing layer 5 with a thickness of approximately 0.2 mm is used.

[0022] <Base material> The base material 6 is laminated onto the backing layer 5 to provide strength and rigidity to the wood grain decorative molded product 100. Specifically, the base material 6 is integrated with the sheet member 110 by insert molding. In this embodiment, the base material 6 is formed from a resin material suitable for insert molding and having excellent strength, heat resistance, and dimensional stability, such as polycarbonate, and is light-transmitting. The base material 6 is transparent or translucent (for example, milky white). In this embodiment, the base material 6 has a thickness of approximately 1.9 mm.

[0023] <Top coat layer> The topcoat layer 7 is laminated on the transparent layer 3 and is intended to improve the appearance of the design surface 101 of the wood grain decorative molded product 100. The topcoat layer 7 is formed of a paint that can be given a mirror finish or a matte finish and transmits light. The topcoat layer 7 is preferably transparent.

[0024] <Penetration section> The through-hole 10 is a through-hole in the sheet member 110 that penetrates the backing layer 5, adhesive layer 4, reinforcing layer 2, and veneer 1. The opening of the through-hole 10 on the surface 11 side of the veneer 1 is covered by the permeable layer 3. The base material 6 is filled into the through-hole 10 from the opening on the back surface 12 side of the veneer 1 in the through-hole 10. The surface of the base material 6 in the through-hole 10 that abuts the permeable layer 3 is flush with the surface 11 of the veneer 1. In other words, the through-hole 10 is not filled with the permeable layer 3, only with the base material 6. That is, the permeable layer 3 does not penetrate into the through-hole 10. As a result, the flat lower surface of the permeable layer 3 on the through-hole 10 and the flat upper surface of the base material 6 in the through-hole 10 abut at the opening on the surface 11 side of the veneer 1 in the through-hole 10. As described above, the through-hole 10 forms characters, patterns, etc. to be displayed in the wood grain decorative molded product 100. In this embodiment, the through-hole 10 is formed by irradiating the sheet member 110 with laser light and partially removing the backing layer 5, adhesive layer 4, reinforcing layer 2, and veneer 1. In this embodiment, a CO2 laser with a wavelength of 10.6 μm is used for laser irradiation. Note that the type of laser and laser wavelength are not limited to the conditions described above, and various types of lasers can be used at any wavelength.

[0025] [2. Method for manufacturing wood grain decorated molded products] Next, the manufacturing method of the wood grain decorated molded product 100 will be explained using Figures 2 and 3A to 3F. As shown in Figure 2, the manufacturing method of the wood grain decorative molded product 100 comprises: laminating a reinforcing layer 2 to the back surface 12 of the veneer 1 (S1); laminating a transparent layer 3 to the front surface 11 of the veneer 1 (S2); forming a sheet member 110 by laminating a backing layer 5 to the reinforcing layer 2 (S3); providing a through portion 10 in the sheet member 110 by processing the sheet member 110 from the backing layer 5 side (S4); joining a base material 6 to the backing layer 5 of the sheet member 110 by insert molding (S5); and laminating a top coat layer 7 to the transparent layer 3 of the sheet member 110 (S6).

[0026] Specifically, in step S1, as shown in Figure 3A, a nonwoven fabric is bonded to the back surface 12 of the veneer 1 using an adhesive (not shown), thereby bonding the reinforcing layer 2 to the back surface 12 of the veneer 1. Next, in step S2, as shown in Figure 3B, a polyester paint is applied to the surface 11 of the veneer 1, which already has the reinforcing layer 2 bonded to its back surface 12, thereby laminating the permeable layer 3 to the surface 11 of the veneer 1. Next, in step S3, as shown in Figure 3C, after bonding the adhesive layer 4 to the reinforcing layer 2, a woven fabric of natural fibers is bonded to the adhesive layer 4, thereby bonding the backing layer 5 to the reinforcing layer 2. In this way, the sheet member 110 is formed by completing steps S1 to S3.

[0027] Next, in S4, as shown in Figure 3D, laser light is irradiated from the backing layer 5 side, and a portion of the backing layer 5, adhesive layer 4, reinforcing layer 2, and veneer 1 of the sheet member 110 is removed, leaving the transparent layer 3 of the sheet member 110, thereby creating a through-hole 10 in the sheet member 110. By creating the through-hole 10 in the sheet member 110 in this way, characters, patterns, etc. that will be displayed on the wood grain decorative molded product 100 are formed.

[0028] Next, in S5, as shown in Figure 3E, the base material 6 is joined to the backing layer 5 of the sheet member 110 by insert molding. At this time, the base material 6 is filled into the through-hole 10. Specifically, the sheet member 110 is set in a mold (not shown), and molten resin material is injected into the backing layer 5 side of the sheet member 110, thereby integrating the sheet member 110 and the base material 6 and molding the whole into a predetermined shape.

[0029] Finally, in S6, as shown in Figure 3F, the topcoat layer 7 is laminated onto the transparent layer 3 of the sheet member 110 by applying a paint that allows for a mirror finish or a matte finish, thereby completing the manufacturing of the wood grain decorated molded product 100.

[0030] [3. Effects] According to the embodiments described in detail above, the following effects can be obtained. (3a) In this embodiment, a transparent layer 3 is provided on the surface 11 of the veneer 1 so as to cover the opening on the surface 11 side of the through-hole 10. In addition, the base material 6 is filled into the through-hole 10 from the opening on the back surface 12 side of the veneer 1 in the through-hole 10. This prevents the formation of steps in the transparent layer 3 near the through-hole 10 and prevents the base material 6 from seeping out onto the surface 11 of the veneer 1 near the through-hole 10. This makes it less likely for the letters and patterns formed by the through-hole 10 to be obscured by steps, and less likely for the letters and patterns to be blurred due to the edges of the through-hole 10 being cut off. Therefore, in the wood grain decorated molded product 100, the letters and patterns formed by the through-hole 10 can be easily recognized.

[0031] (3b) In this embodiment, the wood grain decorative molded product 100 is provided with a through-hole 10, and the top coat layer 7, the transparent layer 3, and the base material 6 are configured to transmit light. Therefore, when a light source 200 is placed on the base material 6 side of the wood grain decorative molded product 100, the light source 200 irradiates light, and by transmitting light through the through-hole 10, letters, patterns, etc. can be illuminated and displayed on the design surface 101 of the wood grain decorative molded product 100. Furthermore, since the through-hole 10 penetrates a veneer 1 or the like that does not transmit light, in a bright environment, letters, patterns, etc. can be recognized on the design surface 101 of the wood grain decorative molded product 100 even without irradiating light from the base material 6 side by the light source 200. In other words, letters, patterns, etc. can be easily recognized on the wood grain decorative molded product 100 regardless of the ambient brightness. Also, the through-hole 10 penetrates the veneer 1. Therefore, compared to a configuration where the through-hole does not penetrate the veneer and letters or other elements are illuminated to display them, the wood grain decorative molded product 100 makes it easier to recognize letters, patterns, etc., regardless of the type of wood used for the veneer.

[0032] (3c) In this embodiment, the sheet member 110 is processed from the backing layer 5 side so that the through portion 10 is provided while leaving the permeable layer 3 intact, and then the base material 6 is joined to the sheet member 110 by insert molding. As a result, the through portion 10 is formed while leaving the permeable layer 3 intact. Therefore, for example, designs that have a portion that is completely surrounded by the through portion 10, such as the letter A, or designs that require fine detail can be easily formed.

[0033] Furthermore, the base material 6 is filled into the through-hole 10 by insert molding while leaving the transparent layer 3 intact. This prevents the base material 6 from seeping out near the through-hole 10 on the surface 11 of the veneer 1, making it less likely for the edges of the through-hole 10 to be cut off and for letters or patterns to become blurred. As a result, it is possible to express the wood grain up to the edges of the letters or patterns formed by the through-hole 10. Also, even if the thickness of the transparent layer 3 is thin, it is possible to prevent the formation of steps in the transparent layer 3 near the through-hole 10, making it easier to obtain a flat surface for the design 101. For example, when a transparent layer is laminated after a through-hole is provided in a veneer, it is necessary to paint until the steps that tend to occur near the through-hole disappear in order to make the design surface flat. On the other hand, in the configuration of this embodiment, it is possible to prevent the formation of steps in the transparent layer 3 near the through-hole 10, so it is not necessary to paint until the steps that tend to occur near the through-hole 10 disappear.

[0034] (3d) In this embodiment, the veneer 1, which is formed by thinly slicing wood, is reinforced by the reinforcing layer 2. This makes it possible to suppress damage to the veneer 1 before it is integrated with the base material 6. In addition, because the veneer 1 is made of wood, the effects of its inherent anisotropy are reduced, which makes it possible to suppress warping and twisting of the wood grain decorated molded product 100.

[0035] (3e) In this embodiment, the reinforcing layer 2 is constrained by the backing layer 5, so deformation of the veneer 1 with the reinforcing layer 2 laminated on it is suppressed. As a result, shrinkage of the sheet member 110, on which the reinforcing layer 2 and the backing layer 5 are laminated, before integration with the base material 6 is less likely to occur, and changes in shape and dimensions can be suppressed. Furthermore, since the backing layer 5 is laminated on the side of the sheet member 110 on which the base material 6 is laminated, it is possible to directly integrate the base material 6 and the backing layer 5 without the use of an adhesive. Moreover, since the backing layer 5 is made of natural fibers, when the base material 6 is integrated with the sheet member 110 by insert molding, the molten resin material enters into the fine irregularities on the surface of the backing layer 5. As a result, a large anchoring effect is secured between the sheet member 110 and the base material 6, so that the sheet member 110 and the base material 6 can be firmly integrated with each other. Therefore, peeling and lifting of the sheet member 110 from the base material 6 can be suppressed.

[0036] (3f) In this embodiment, a transparent layer 3 and a topcoat layer 7 are laminated on the surface 11 of the veneer 1. As a result, the smoothness of the design surface 101 is increased, resulting in a more beautifully finished wood grain decorative molded product 100, and the durability of the wood grain decorative molded product 100 is increased by protecting the design surface 101.

[0037] (3g) In this embodiment, the permeable layer 3 and the topcoat layer 7 are formed by painting. Therefore, even if the surface of the veneer 1 has a complex shape because it is formed from natural wood, the permeable layer 3 is painted to fill the gaps on the surface caused by the pores of the veneer 1, making the letters and patterns formed by the through-holes 10 stand out more. In addition, in the process of laminating the permeable layer 3 and the topcoat layer 7, the process of painting, grinding, and painting is repeated, so that sink marks and unevenness of the pores of the veneer 1 that may occur in the wood grain decorative molded product 100 by insert molding can be made flat.

[0038] [4. Other Embodiments] While embodiments of this disclosure have been described above, it goes without saying that this disclosure is not limited to the embodiments described above and can take various forms.

[0039] (4a) In the above embodiment, the wood grain decorative molded product 100 was exemplified as being used as an interior part of an automobile, but the uses of the wood grain decorative molded product 100 are not limited to this. For example, the wood grain decorative molded product may be used for furniture, home appliances, etc. Also, for example, the wood grain decorative molded product may be used in a way that a sensor is embedded in the through-hole so that the sensor reacts when the through-hole is touched, and the through-hole acts as a switch. Also, for example, if a light source is placed on the base material side of the wood grain decorative molded product, it is possible to achieve a variety of expressions in the letters, patterns, etc. formed by the through-hole by changing the color of the light source.

[0040] (4b) In the above embodiment, a wood grain decorative molded product 100 was illustrated in which a top coat layer 7, a transparent layer 3, a veneer 1, a reinforcing layer 2, an adhesive layer 4, a backing layer 5, and a base material 6 were laminated in that order from top to bottom. However, the configuration of the wood grain decorative molded product is not limited to this. For example, the wood grain decorative molded product may have a configuration that includes at least a transparent layer 3, a veneer 1, and a base material 6. In other words, the wood grain decorative molded product may have a configuration that does not include at least one or all of the top coat layer 7, the reinforcing layer 2, the adhesive layer 4, and the backing layer 5.

[0041] (4c) In the above embodiment, the veneer 1 was formed from a solid base material, but the veneer may be subjected to, for example, bleaching or dyeing treatment. By bleaching the veneer, its color is lightened, making it possible to obtain a veneer with less color unevenness. By dyeing the veneer, the veneer is colored, and its color tone can be easily adjusted to a desired color tone. Furthermore, if the veneer is subjected to both bleaching and dyeing treatments, it is possible to easily obtain a veneer with less color unevenness and a desired color tone.

[0042] (4d) In the above embodiment, the reinforcing layer 2 was formed of a nonwoven fabric, but the reinforcing layer may be formed of, for example, ordinary paper, Japanese paper, or chemical fibers.

[0043] (4e) In the above embodiment, the permeable layer 3 was formed by coating the veneer 1 with polyester paint, but the permeable layer may be formed with, for example, acrylic paint. Furthermore, the permeable layer is not limited to being formed by coating, but may also be formed by bonding a plate material such as a polycarbonate resin plate or an acrylic resin plate to the veneer 1 using, for example, an epoxy-based, olefin-based adhesive or a UV-curing adhesive.

[0044] (4f) In the above embodiment, the adhesive layer 4 was formed with an aqueous vinyl urethane adhesive, but the adhesive layer may be formed with, for example, an epoxy or olefin adhesive.

[0045] (4g) In the above embodiment, the backing layer 5 was formed from a woven fabric using natural fibers, but the backing layer may be formed from, for example, ordinary paper, Japanese paper, chemical fibers, wood-based materials such as veneer, etc. Also, for example, a light-shielding material may be used for the backing layer. When the backing layer is formed from a light-shielding material in this way, light is less likely to pass through in parts other than the light-transmitting through-holes 10, so it is possible to make the characters etc. formed by the through-holes 10 stand out more.

[0046] (4h) In the above embodiment, the base material 6 was formed of polycarbonate resin, but the base material may be formed of, for example, ABS resin or PP resin.

[0047] (4i) In the above embodiment, a top coat layer 7 formed by paint was provided on the outer surface of the wood grain decorated molded product 100, but the wood grain decorated molded product may be configured without a top coat layer 7. In that case, the appearance of the design surface of the wood grain decorated molded product may be improved by polishing the transparent layer 3.

[0048] (4j) In the above embodiment, the through-hole 10 was formed by irradiation with laser light, but the through-hole may also be formed, for example, by removing the backing layer 5, adhesive layer 4, reinforcing layer 2 and veneer 1 of the sheet member 110 with a cutting tool or the like.

[0049] (4k) The functions of one component in the above embodiment may be distributed among multiple components, or the functions of multiple components may be integrated into one component. Also, some parts of the configuration of the above embodiment may be omitted. Also, at least some parts of the configuration of the above embodiment may be added to, replaced with, etc., the configuration of other above embodiments. [Explanation of symbols]
