Definitions

• the present disclosure relates to a wood material sheet using natural wood, a method for manufacturing a wood material sheet, a molded product, and a method for manufacturing a molded product.
• Patent Document 1 discloses a wooden decorative board in which a protective layer is formed by transfer on the upper part of the veneer. This configuration is shown in FIGS. 14 and 15. FIG.
• the wooden decorative board 108 in FIGS. 14 and 15 is composed of a transfer layer 101, a veneer 102, a nonwoven fabric 103, and a first adhesive layer 104.
• the transfer layer 101 is formed on the release layer 105 and transferred to one side of the projecting plate 102 by hot pressing to form unevenness 106 similar in shape to the surface unevenness of the projecting plate 102 .
• a hard coat layer 108 and a veneer adhesive layer 107 are formed as a transfer layer 101 on a release layer 109 of a base film 110, and serve as a protective layer for the veneer 102 surface. Since the transfer layer 101 is a thin film, it is configured to maintain the original tactile feel and appearance of the veneer 102 while ensuring durability for use in industrial products.
• the veneer 102 is impregnated with a resin material as necessary.
• the veneer may be treated with a colored layer.
• a coating material used for forming the colored layer contains a coloring component and a solvent component, and the solvent component may contain a substance having a boiling point higher than room temperature. The handling of this solvent component has also not been considered until now.
• the present inventors found the handling of the water content of the sliced veneer and the solvent component of the colored layer as a subject for further improvement, leading to the present disclosure.
• An object of the present invention is to provide a wood material sheet that can solve the problems related to the water content of veneer and the solvent component of the colored layer.
• the wood material sheet according to the present disclosure includes a natural wood material, a thermoplastic shape-following layer provided on one side of the wood material, a support layer, and a colored pattern layer, a second adhesive layer, a first adhesive layer, and a protective layer provided on the other side of the wood material.
• the method of manufacturing a wood sheet according to the present disclosure includes the steps of laminating a thermoplastic shape-conforming layer and a support layer on one surface of a wood material to form a laminate, forming a colored pattern layer and a second adhesive layer on the other surface of the wood material of the laminate, bringing the first adhesive layer of a sheet obtained by laminating a protective layer and a first adhesive layer into contact with the second adhesive layer of the laminate, and thermocompression bonding the sheet and the laminate to obtain a wood material sheet. .
• a molded article according to the present disclosure includes the wood sheet and at least one member selected from the group consisting of a resin member, a metal member, a glass member, a ceramic member, and a wood material provided on the support layer side of the wood material sheet.

• the wood material sheet 31 with the release layer 52 and the base film 51 attached may be used for integration, or the integration may be performed after removing them in advance.
• the wooden material sheet 31 is taken up as an example, but it is not limited to this.
• the wooden material sheet 32, the wooden material sheet 33, and the wooden material sheet 34 described in the second and third embodiments can be integrated with the reinforcing layer 12 by the same process as described in the fourth embodiment.
• the molded product may include the wood sheet and at least one member selected from the group consisting of a resin member, a metal member, a glass member, a ceramic member, and a wood member provided on the support layer side of the wood sheet.
• the molded article may be formed by injection molding using the wood material sheet, for example. Specifically, it may be manufactured by the following steps. (a) Arranging the wooden material sheet in a fixed mold or a movable mold. (b) injecting resin into the cavity between the fixed mold and the movable mold; (c) After the resin has hardened, the fixed mold and the movable mold are opened to take out the molded article containing the wooden material sheet.
• a molded article by the following processes.
• (i) Prepare a wood material sheet.
• (ii) A wood material sheet is pasted on at least one surface selected from the group consisting of a resin member, a metal member, a glass member, a ceramic member, and a wood material to form a molded product.
• the wooden sheet according to the present disclosure contributes to high functionality and high design in fields requiring decoration such as the exterior of various home electric appliances and the interior of vehicles.
