Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a decorative panel used as a door for furniture, a wainscot, a wall covering for a house, a store, an office, etc. [Prior Art] Conventionally, a decorative panel (hereinafter referred to as a decorative panel) is formed by processing a thermosetting resin decorative board into a curved shape.
The thermosetting resin decorative laminate is post-formed along a core material having a curved surface shape, or the impregnated paper of the thermosetting resin decorative laminate is hot pressure molded or vacuum formed in a mold having a curved surface shape. obtained by processing. [Problems to be Solved by the Invention] Conventionally, decorative panels having a curved shape obtained by post-form processing, vacuum press processing, etc. have been manufactured using core materials such as plywood or particle board processed into various shapes, or a desired shape. It requires molds, jigs, etc. of the same size as the product, and there are problems in that it is time-consuming and time-consuming to set up a type change during the manufacturing process. Furthermore, decorative materials such as thermoplastic resins such as soft vinyl chloride resins, paper, and cloth conventionally used for wall decoration etc. have problems such as poor surface properties and easy staining and scratching. The present invention was invented in view of the above-mentioned problems of the prior art, and provides a decorative panel with a curved surface processing that simplifies the setup process and has excellent surface properties, and a method for manufacturing the same. It's about doing. [Means for Solving the Problems] In order to achieve the above object, the decorative panel of the present invention contains melamine resin, diallyl phthalate resin,
Thermosetting resin decorative board with a thickness of 0.2 to 2.0 mm, such as polyester resin, is made of synthetic foam resin such as foamed urethane resin or foamed phenol resin, or wood material such as balsa wood, and has no resilience even when compressed. After laminating and integrating with the cushioning material, which is an elastic body, a mold made of a metal material such as aluminum or brass and having a curved surface is pressed onto the thermosetting resin decorative board. A decorative panel with a curved surface is obtained. [Example] An example will be described with reference to the drawings. A, B, and C in FIG. 2 show the manufacturing process of the decorative panel of the present invention shown in FIG. 1, and the decorative panel is manufactured as follows. A diallyl phthalate resin decorative board 2 with a thickness of 0.3 mm and a hard urethane resin foam board 3 with a foaming ratio of 10 times and a thickness of 8 mm are placed on a base material 4 such as a particle board with a thickness of 15 mm using an adhesive such as a urethane resin adhesive. 5, they are laminated and integrated as shown in A of FIG. Next, an aluminum mold 6 having a diameter of 5 mmR is pressed from the top of the diallyl phthalate resin decorative board 2 at a temperature of 120°C and a pressure of 5 kg/cm ² , so that the diallyl phthalate resin decorative board 2 and the hard A decorative panel 1 of the present invention having a curved surface of 5 mm radius is manufactured by laminating and integrating a urethane resin foam board 3.
Furthermore, as shown in FIG. 2C, the decorative panel 1 can also be used as a decorative panel 1' whose edges are curved by cutting with a circular saw or the like from the concave portion 7 embossed with the mold 6. I can't help it. The foaming ratio of the hard urethane resin foam board is 6.
It is desirable that the magnification is from 1 to 15 times; if the magnification is low, embossing becomes impossible, and if the magnification is high, dents may occur even with the pressure of a finger, which is undesirable. The decorative panel 1 is used as a decorative decorative panel by being attached to a crosspiece 8 provided on a wall base material, as shown in FIG. 3, or as a door for furniture, etc., as shown in FIG. 4. [Effects of the Invention] Since the decorative panel of the present invention is manufactured as described above, there is no need to prepare various types of core materials processed into curved shapes such as postform processing.
Unlike press processing, there is no need to prepare male and female molds that match the product size. In other words, it is manufactured using a flat plate in which a thermosetting resin decorative board and a cushioning material are laminated and integrated, and a mold for only the part to be curved, which may be laminated and integrated with a base material such as particle board. Therefore, it can be expected to simplify the process and save labor in the setup process. In addition, the foamed synthetic resin board used as the cushioning material is not foamed and hardened, but instead uses foamed resin or a sheet impregnated with it, which also serves as an adhesive when laminated with a thermosetting resin decorative board. If so, there is no need to provide a new bonding process, and the process can be further simplified. The decorative panel of the present invention has a surface covered with a thermosetting resin decorative board that has excellent abrasion resistance, stain resistance, and hardness, so it can be used with a decorative board made of thermoplastic resin such as soft vinyl chloride, It has superior surface properties and durability compared to decorative materials such as paper and cloth. Furthermore, when a foamed synthetic resin body is used as a cushioning material, heat insulation and sound insulation effects can also be expected.
