Summary of the Invention

Problems to be Solved by the Invention

[0005] However, for example, when forming a base material by injection molding on a decorative layer by inkjet printing, such as when creating a decorative panel, due to dimensional changes, the surface material that protects the decorative layer may peel off together with the decorative layer from a portion where the adhesive force is weak.

[0006] In addition, when laminating a decorative layer and a resin in a conventional decorated decorative panel, there is a method of applying an adhesive, but in that case, the number of steps for laminating the adhesive increases, resulting in a large amount of man-hours.

[0007] The present invention has been made in view of the above problems, and an object thereof is to provide a resin laminate and a method for manufacturing the resin laminate capable of ensuring adhesive strength with a small number of man-hours.

Means for Solving the Problems

[0008] In order to achieve the above object, the resin laminate according to the first invention includes a surface material, a base material, and a decorative layer. The surface material is formed of a transparent resin material. The base material is formed of a resin material. The decorative layer is disposed between the surface material and the base material and has ink. At least a part of the surface material is in direct contact with the base material.

[0009] Here, since the adhesion between the base material and the surface material is greater than that between the base material and the decorative layer, peeling of the surface material from the base material can be suppressed by bringing at least a part of the surface material into contact with the base material without contacting the decorative layer.

[0010] By partially removing the ink without laminating an adhesive as in the prior art, the adhesive strength can be ensured with a small number of man-hours.

[0011] The resin laminate according to the second invention is the resin laminate according to the first invention, wherein the peripheral portion of the surface material is in direct contact with the base material.

[0012] By bringing the peripheral portion of the surface material into contact with the base material without contacting the decorative layer, peeling of the surface material from the base material at the peripheral portion can be suppressed.

[0013] The resin laminate according to the third invention is the resin laminate according to the second invention, wherein the width of the peripheral portion is 5 mm or less.

[0014] Thereby, peeling of the surface material can be suppressed while ensuring the decorativeness. Thereby, the decoration can be visually recognized.

[0015] The resin laminate according to the fourth invention is the resin laminate according to the second or third invention, wherein the surface material has a plate-shaped main body portion. The peripheral portion is formed outside the main body portion. The peripheral portion is formed to incline outward or vertically from the main body portion toward the base material side.

[0016] As a result, when viewed perpendicularly to the surface of the surface material, the peripheral portion where the decorative layer is not formed becomes difficult to visually recognize, so that the decorativeness can be ensured.

[0017] The method for manufacturing a resin laminate according to the fifth invention includes a decorative layer forming step and a base material forming step. The decorative layer forming step discharges ink onto the surface of a surface material formed of a transparent resin material and forms a decorative layer by leaving at least a part of the surface material. The base material forming step injects a resin material onto at least a part of the surface material and on the decorative layer to form a base material.

[0018] Here, since the adhesion between the base material and the surface material is greater than that between the base material and the decorative layer, peeling of the surface material from the base material can be suppressed by bringing the base material into contact with at least a part of the surface material without bringing the decorative layer into contact therewith.

[0019] By partially removing the ink without laminating an adhesive as in the conventional case, the adhesive strength can be ensured with a small number of man-hours.

Effect of the Invention

[0020] According to the present invention, it is possible to provide a resin laminate capable of suppressing peeling of a surface material and a method for manufacturing the resin laminate.

Mode for Carrying Out the Invention

[0022] Hereinafter, a decorative panel, which is an example of the resin laminate of the present invention, and a manufacturing method of the decorative panel will be described in detail with reference to the drawings.

[0023] <1. Configuration> (1-1. Outline of the decorative panel 10) FIG. 1 is a perspective view of the decorative panel 10 of the present embodiment. FIG. 2 is a cross-sectional view of the decorative panel 10 of the present embodiment. Note that the perspective view of FIG. 1 includes a partial cross-sectional view.

[0024] Also, in the following description, the up-down direction coincides with the up-down direction in FIG. 2, but is not limited thereto, and the direction may change depending on the position where the decorative panel 10 is disposed.

[0025] The decorative panel 10 (an example of a resin laminate) of the present embodiment is used, for example, for floor materials and the like. The decorative panel 10 includes a surface material 1, a decorative layer 2, and a base material 3. The surface material 1 is formed of a transparent resin material. The base material 3 is formed of a resin material. The decorative layer 2 is disposed between the surface material 1 and the base material 3.

[0026] (1-2. Surface Material 1) FIG. 3 is a perspective view of the surface material 1 viewed from above. FIG. 4 is a perspective view of the surface material 1 viewed from below. FIG. 5 is a cross-sectional view of the surface material.

[0027] The surface material 1 has a plate-shaped main body portion 11 and side wall portions 12 (an example of a peripheral portion). The main body portion 11 is formed in a rectangular shape. The side wall portions 12 are formed to incline in a flared manner from the periphery of the main body portion 11. The side wall portions 12 form the peripheral portion of the surface material 1. The main body portion 11 and the side wall portions 12 are integrally formed. The surface material 1 has an upper surface 1a (which can also be said to be the surface) and a lower surface 1b (which can also be said to be the back surface).

[0028] A recess 1c surrounded by the lower surface 11b (which can also be said to be the back surface) of the main body portion 11 and the inner wall surface 12b of the side wall portions 12 is formed on the lower surface 1b of the surface material 1.

[0029] From the viewpoints of wear and cost, the thickness W1 of the surface material 1 is preferably, for example, 0.1 mm or more and 5 mm or less. More preferably, it is 0.5 mm or more and 5 mm or less.

[0030] The surface material 1 is not particularly limited as long as it is formed of a transparent resin material, and it is more preferable to be formed of a resin material with high transparency.

[0031] As the material of the surface material 1, for example, it can be formed from at least one selected from acrylic resins such as acrylonitrile-styrene copolymers, polyolefin resins such as polyethylene, polycarbonate resins, polycarbonate resins, or polyester resins such as polyethylene terephthalate.

[0032] (1-3. Decorative layer) The decorative layer 2 is formed by various patterns, colors, etc., and decorates the decorative panel 10. As shown in FIG. 2, the decorative layer 2 is formed on the lower surface 11b of the main body portion 11 of the surface material 1. The decoration by the decorative layer 2 can be visually recognized from the outside through the transparent surface material 1. Also, the decorative layer 2 is not formed on the inner wall surface 12b of the side wall portion 12.

[0033] The decorative layer 2 can be printed non - contact on the lower surface 11b of the main body portion 11 of the surface material 1 by an inkjet printer.

[0034] In this case, it may be printed directly on the lower surface 11b of the surface material 1, or may be printed after performing a primer treatment or a discharge treatment on the lower surface 11b of the surface material 1 to improve adhesiveness. Also, these treatments may be performed on the decorative layer 2 after printing.

[0035] The ink ejected by the inkjet printer uses ink according to known techniques. For example, UV or EB curable ink containing a monomer as the main component and one or more of other additives such as oligomers, colorants, dispersants, photoinitiators, surfactants (citation: Journal of the Japan Society for Imaging Science, Vol. 49, No. 5, Hardening characteristics of UV inkjet and Polymer, Vol. 34, November issue (1985), Electron beam curable resin).

[0036] Alternatively, for example, penetration, evaporation, drying, acid - polymerization drying, or thermosetting ink obtained by dissolving (or dispersing) a known colorant (dye or pigment) together with a binder resin in a solvent (or dispersion medium) may be used. These may be used in combination. The decorative layer 2 is formed by being printed on the lower surface 11b of the surface material 1 by an inkjet printer.

[0037] The film pressure W2 of the decorative layer 2 is preferably 10 μm or more. FIG. 6 is a perspective view of the surface material 1 and the decorative layer 2 as viewed from the decorative layer 2 side. FIG. 6 is a plan view showing a state in which the base material 3 is removed from the decorative panel 10.

[0038] As shown in FIGS. 2 and 6, the decorative layer 2 is not formed on the inner wall surface 12b of the side wall portion 12 of the surface material 1. The side wall portion 12 is a region at a distance L1 along the surface material 1 from the end of the surface material 1. The distance L1 is a distance parallel to the lower surface 11b of the surface material 1.

[0039] In other words, the decorative layer 2 is disposed on the lower surface 1b of the surface material 1 with a predetermined distance L1 from the end 1e of the surface material 1. If the distance L1 is too large, the appearance will be deteriorated. Therefore, for aesthetic reasons, it is set to, for example, 5 mm or less. Note that the distance L1 does not have to be constant over the entire circumference.

[0040] (1-4. Base material 3) FIG. 7 is a perspective view of only the base material 3 as viewed from above. FIG. 8 is a perspective view of the base material 3 as viewed from below.

[0041] As shown in the figure, the base material 3 supports the surface material 1. The base material 3 is disposed on the surface 2b opposite to the surface 2a on the surface material 1 side of the decorative layer 2 as shown in FIG. 2.

[0042] The base material 3 is disposed on the surface 1b side of the surface material 1 via the decorative layer 2 in the portion where the decorative layer 2 is disposed, and is disposed in direct contact with the side wall portion 12 of the surface material 1 outside the decorative layer 2. The base material 3 is formed by insert molding.

[0043] The base material 3 has a base portion 31 and a convex portion 32. The base portion 31 is formed in a rectangular plate shape. The convex portion 32 is rectangular and is formed on the upper surface of the base portion 31.

[0044] The convex portion 32 is formed in a shape that fits into the concave portion 1c of the surface material 1, and is formed in a trapezoidal shape in a cross-sectional view. The convex portion 32 has an upper surface 321 having the same shape as the lower surface 11b of the main body portion 11 of the surface material 1, and side surfaces 322 that extend downward in a flared manner from the upper surface 321.

[0045] The side surfaces 322 are formed in the same shape as the inner wall surface 12b of the side wall portion 12 of the surface material 1. Such a convex portion 32 and the concave portion 1c of the surface material 1 form a raised portion on the decorative panel 10.

[0046] The base material 3 is formed of a resin material, and this resin material is not particularly limited. However, for example, a material that is easily elastically deformed to absorb the impact received by the decorative panel 10 is preferable.

[0047] As such a material, for example, it can be formed from at least one resin material selected from vinyl chloride resins such as PVC, olefin resins such as polyethylene, acrylic resins such as acrylonitrile-styrene copolymers and acrylonitrile-ethylene-styrene copolymers, or ABS resin. Also, from the viewpoint of the adhesiveness with the ink of the decorative layer 2, it is preferably formed of a resin material having polarity.

[0048] <2. Manufacturing method of the decorative panel 10> Next, the manufacturing method of the decorative panel 10 of the present embodiment will be described.

[0049] FIG. 9 is a flowchart showing the manufacturing method of the decorative panel 10 of the present embodiment. FIGS. 10(a), 10(b), 11(a), 11(b), and 12 are cross-sectional views for explaining the manufacturing method of the decorative panel 10.

[0050] First, in step S10, as shown in FIG. 10(a), ink 130 is ejected from an inkjet printer 120 onto the lower surface 11b of the main body portion 11 of the surface material 1, and the ink is applied to the lower surface 11b, and as shown in FIG. 10(b), a decorative layer 2 is formed. Here, the ink 130 is ejected so that the decorative layer 2 is not formed on the inner wall surface 12b of the side wall portion 12 of the surface material 1.

[0051] Next, in step S20, a base material 3 is formed by insert molding on the decorative layer 2 and the side wall portion 12 of the surface material 1.

[0052] Specifically, as shown in FIG. 11(a), the surface material 1 and the decorative layer 2 are arranged in a mold 200. The mold 200 has a first mold 201 and a second mold 202. A gate 210 for injecting a resin material into the mold is formed in the first mold 201. The surface material 1 and the decorative layer 2 are arranged in the second mold 202. In the present embodiment, two gates 210 are formed.

[0053] As shown in FIG. 11(b), after the surface material 1 and the decorative layer 2 are arranged in the second mold 202, the first mold 201 and the second mold 202 are closed. Then, the resin material is injected into the mold 200 from the gate 210, and as shown in FIG. 12, the base material 3 is formed. Then, the produced decorative panel 10 is taken out from the mold 200.

[0054] <3. Example> Next, the decorative panel of the present embodiment will be described using an example.

[0055] A three-point bending test was performed using the decorative panel 10 described in the above embodiment and, as a comparative example, the decorative panel 100 shown in FIG. 13. The decorative panel 100 has a configuration in which a decorative layer 2 is formed on the entire lower surface 1b of the surface material 1 (the decorative layer 2 is formed on the inner wall surface 12b of the side wall portion 12), and a base material 3 is arranged on the lower surface 2b of the decorative layer 2.

[0056] In the cosmetic panels of Example 1 and Comparative Example 1, 1.1 mm of PMMA resin (polymethyl methacrylate resin) was used as the surface material 1, and AES resin (acrylonitrile·ethylene·styrene copolymer) was used as the base material 3.

[0057] For the three-point bending test, as shown in FIGS. 11(a) and 11(b) for example, using a cosmetic panel with a side length of 150 mm, the cosmetic panel was supported by a pair of fulcrums 300, a 12.5R load cell was installed at the midpoint with a distance of 125 mm, and the three-point bending test was carried out. Then, the load at the time of fracture (peeling) when a load was applied to the center of the cosmetic panel was measured. Here, peeling means peeling between the surface material and the decorative layer, or between the decorative layer and the base material.

[0058] FIG. 15 is a diagram showing a table of the results of Examples 1 to 4 and Comparative Examples 1 to 4. In Example 1, the load was 771 N, and in Comparative Example 1, the load was 359 N.

[0059] In the cosmetic panels of Example 2 and Comparative Example 2, 0.5 mm of PMMA resin (polymethyl methacrylate resin) was used as the surface material 1, and AES resin (acrylonitrile·ethylene·styrene copolymer) was used as the base material 3. In Example 2, the load was 1284 N, and in Comparative Example 2, the load was 376 N.

[0060] In the cosmetic panels of Example 3 and Comparative Example 3, 1.1 mm of PC resin (polycarbonate resin) was used as the surface material 1, and AES resin (acrylonitrile·ethylene·styrene copolymer) was used as the base material 3. In Example 3, the load was 989 N, and in Comparative Example 3, the load was 376 N.

[0061] In the cosmetic panels of Example 4 and Comparative Example 4, 0.7 mm of PC resin (polycarbonate resin) was used as the surface material 1, and AES resin (acrylonitrile·ethylene·styrene copolymer) was used as the base material 3. In Example 4, the load was 1655 N, and in Comparative Example 4, the load was 370 N.

[0062] From the above, it can be seen that when the base material 3 is directly contacted with the side wall portion 12 of the surface material 1 without providing the decorative layer 2, it has higher rigidity and can suppress peeling compared to arranging the base material 3 via the decorative layer 2 on the side wall portion 12 of the surface material 1.

[0063] <4. Features, etc.> (4-1) The decorative panel 10 (an example of a resin laminate) of the present embodiment includes a surface material 1, a base material 3, and a decorative layer 2. The surface material 1 is formed of a transparent resin material. The base material 3 is formed of a resin material. The decorative layer 2 is disposed between the surface material 1 and the base material 3 and has ink. At least a part of the surface material 1 is in direct contact with the base material 3.

[0064] Here, since the adhesion between the base material 3 and the surface material 1 is greater than that between the base material 3 and the decorative layer 2, peeling of the surface material 1 from the base material 3 can be suppressed by bringing the base material 3 into contact with the side wall portion 12 of the surface material 1 without bringing it into contact with the decorative layer 2.

[0065] By partially removing the ink without laminating an adhesive as in the prior art, the adhesive strength can be ensured with fewer man-hours.

[0066] (4―2) In the decorative panel 10 (an example of a resin laminate) of the present embodiment, the side wall portion 12 (an example of a peripheral portion) of the surface material 1 is in direct contact with the base material 3.

[0067] By bringing the base material 3 into contact with the side wall portion 12, which is the peripheral portion of the surface material 1, without bringing it into contact with the decorative layer 2, peeling of the surface material 1 from the base material 3 at its peripheral portion can be suppressed.

[0068] (4-3) In the decorative panel 10 (an example of a resin laminate) of the present embodiment, the width L1 of the side wall portion 12 is 5 mm or less. Thereby, peeling of the surface material 1 can be suppressed while ensuring decorativeness.

[0069] (4-4) In the decorative panel 10 (an example of a resin laminate) of the present embodiment, the surface material 1 has a plate-shaped main body portion 11. A side wall portion 12 (an example of a peripheral portion) is formed outside the main body portion 11. The side wall portion 12 is formed to incline outward from the main body portion 11 toward the base material 3 side.

[0070] As a result, when viewed perpendicular to the surface 1a of the surface material 1, the side wall portion 12 where the decorative layer 2 is not formed becomes difficult to visually recognize, so that decorativeness can be ensured.

[0071] (4-5) The manufacturing method of the decorative panel 10 (an example of a resin laminate) of the present embodiment includes a step S10 (an example of a decorative layer forming step) and a step S20 (an example of a base material forming step). In step S10 (an example of a decorative layer forming step), ink 130 is discharged onto the surface 1b of the surface material 1 formed of a transparent resin material, and a decorative layer 2 is formed by leaving at least a part of the surface material 1 empty. In step S20 (an example of a base material forming step), a resin material is injected onto at least a part of the surface material 1 and on the decorative layer 2 to form the base material 3.

[0072] Here, since the adhesion between the base material 3 and the surface material 1 is greater than that between the base material 3 and the decorative layer 2, by bringing the base material 3 into contact with at least a part of the surface material 1 without bringing the decorative layer 2 into contact, peeling of the surface material 1 from the base material 3 can be suppressed.

[0073] By partially removing the ink without laminating an adhesive as in the conventional case, the adhesive strength can be ensured with a small number of man-hours.

[0074] <5. Other Embodiments> As described above, the embodiments of the resin laminate and the manufacturing method of the resin laminate according to the present invention have been described. However, the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the gist thereof.

[0075] (A) In the above embodiment, the center of the decorative panel 10 bulges, but it does not have to bulge. FIG. 16 is a perspective view of the non-bulging decorative panel 20, and FIG. 17 is a cross-sectional view of the decorative panel 20.

[0076] As shown in FIG. 17, the decorative panel 20 has a surface material 21, a decorative layer 22, and a base material 23. The surface material 21 is box-shaped, and the base material 23 is disposed inside thereof. The decorative layer 22 is formed on the surface 21b on the base material 23 side of both surfaces of the surface material 21. Further, the decorative layer 22 is not formed on the side wall portion 211 of the surface material 21.

[0077] The side wall portion 211 is a region at a distance L1 from the lower end 21e of the surface material 21. In other words, the decorative layer 22 is disposed on the lower surface 21b of the surface material 21 with a predetermined distance L1 from the lower end 21e of the surface material 21. The base material 23 is formed in a plate shape, and no convex portion 32 or the like is provided as compared with the base material 23.

[0078] The base material 23 is disposed on the surface 21b side of the surface material 21 via the decorative layer 22 in the portion where the decorative layer 22 is disposed, and is disposed in direct contact with the side wall portion 211 of the surface material 21 on its side surface.

[0079] (B) In the above embodiment, two gates 210 are formed, but it is not limited to two, and further, the location is not limited to the location as shown in FIG. 11(b).

[0080] (C) In the above embodiment, a portion (peripheral edge portion 1d) that is in direct contact with the base material 3 is provided over the entire circumference of the surface material 1, but it does not have to be limited to the entire circumference, and the decorative layer 2 may be formed on a part of the side wall portion 12 of the surface material 1. However, forming a portion that is in direct contact with the base material 3 over the entire circumference of the surface material 1 can further suppress the peeling of the surface material.

[0081] (D) In the above-described embodiment, the decorative layer 2 is not formed over the entire side wall portion 12, but the decorative layer 2 may be formed up to midway from the end of the lower surface 11b of the main body portion 11 toward the end 1e.

[0082] Also, the decorative layer 2 does not necessarily have to be formed not only on the side wall portion 12 but also on a part of the lower surface 11b.

[0083] (E) In the above-described embodiment, the side wall portion 12, which is an example of the peripheral edge portion of the surface material 1, is in direct contact with the base material 3, but the present invention is not limited to such a configuration, and at least a part of the surface material 1 and the base material 3 may be in direct contact with each other.

[0084] FIGS. 18(a), (b) and FIGS. 19(a), (b) are plan views showing examples of decorative panels in which the portions where the surface material 1 and the base material 3 are in direct contact are different from those in the embodiment.

[0085] In the decorative panel 70 of FIG. 18(a), the main body portion 11 and the base material 3 are in direct contact with each other in a lattice pattern. In other words, in addition to the side wall portion 12, the surface material 1 is in direct contact with the base material 3 in a cross shape on the main body portion 11 in plan view. In FIG. 18(a), the portion inside the surface material 1 where the decorative layer 72 (dot portion) is not formed is the portion where the surface material 1 and the base material 3 are in direct contact with each other. The same applies to the following figures.

[0086] In FIG. 18(a), among the portions in direct contact, the portion of the side wall portion 12 is indicated as C71, and the cross-shaped portion is indicated as C72. The portion in direct contact C71 is not limited to the entire side wall portion 12, and may be formed from the outer peripheral end of the side wall portion 12 to midway of the side wall portion 12, or may be formed from the outer peripheral end of the side wall portion 12 to the main body portion 11.

[0087] In the decorative panel 40 shown in Fig. 18(b), a decorative layer 42 is shown, and inside the outermost peripheral side wall portion 12, the surface material 1 and the base material 3 are in direct contact with each other along the side wall portion 12 over a full circle. This directly contacting portion is denoted as C41. The directly contacting portion C41 may be formed only on the side wall portion 12, or may be formed from the side wall portion 12 to the main body portion 11.

[0088] In the decorative panel 50 shown in Fig. 19(a), a decorative layer 52 is shown, and only the four corners of the surface material 1 are in direct contact with the base material 3. The directly contacting portion is denoted as C51. This directly contacting portion C51 may be formed from the side wall portion 12 to the main body portion 11, or may be formed only on the side wall portion 12.

[0089] In the decorative panel 60 shown in Fig. 19(b), a decorative layer 62 is shown, and the portions where the surface material 1 and the base material 3 are in direct contact are provided randomly. This directly contacting portion is denoted as C61, and it may be formed randomly not limited to the main body portion 11 and the side wall portion 12. Thus, it is sufficient that at least a part of the surface material 1 is in direct contact with the base material 3.

[0090] (F) In the above embodiment, the side wall portion 12 is formed to incline outward from the main body portion 11 toward the base material 3 side, but it is not limited thereto. For example, the side wall portion 12 may be formed perpendicular to the base material 3 side from the main body portion 11.

[0091] (G) Also, within the scope not departing from the gist of the present invention, it is possible to appropriately replace the constituent elements in the above-described embodiment with well-known constituent elements.
