Abstract

PURPOSE:To simplify a set up process and obtain a decorative panel which is superior in surface physical properties and subjected to curved surface processing, by a method wherein after unification through lamination of a thermosetting resin decorative sheet and cushioning material comprised of synthetic foamed resin or a ligneous material, the decorative sheet is embossed with a mold on which curved surface processing is performed. CONSTITUTION:A diallyl phthalate resin decorative sheet 2, which is about 0.3mm in thickness, and hard urethane resin foamed board 3 whose expansion ratio and thickness are respectively 10 times and 8mm are laminated onto a base material 4 such as a particle board, which is 15mm in thickness, for unification through an adhesive agent. Then a mold 6 made of Al having the radius of 5mm R is embossed on the decorative sheet 2 under a condition where a temperature is 120 deg.C and pressure is 5kg/cm<2> and a decorative panel 1 where the decorative sheet 2 and foamed board 3 are unified through lamination and the same having a curved surface of 5mm R is formed. It is preferable that expansion ratio of the hard urethane resin foamed board is about 6-15 times, when the expansion ratio is low, embossment becomes impossible and when the same is high on the contrary, it is not preferable since a depression is generated even with pressure of such an extent as to press with a finger.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to decorative panels used as doors of furniture, wainscoting, wall coverings of houses, stores, offices, etc. [Prior Art] Conventionally, A decorative panel made of a thermosetting resin decorative board processed into a curved shape (hereinafter referred to as a decorative panel) is either a post-form processing of the thermosetting resin decorative board along a core material having a curved shape, or The paper impregnated with the thermosetting resin decorative board is obtained by hot-pressure molding and vacuum molding in a curved mold.

[Problem to be solved by the invention]

Conventionally, decorative panels with curved shapes 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, and molds and treatments of the same size as the desired product. Requires tools etc.
When setting up a type change in the manufacturing process, there are problems such as it is time consuming and time consuming. In addition, decorative materials such as thermoplastic resins such as soft vinyl chloride resin, paper, and cloth conventionally used for wall decoration have poor surface properties and have problems such as being easily stained and scratched. be.

The present invention was invented in view of the above-mentioned problems of the prior art, and provides a nine-faced decorative panel that simplifies the setup process and has a curved surface with excellent surface properties, and a method for manufacturing the same. Then there is K.

[Rounding method to solve the problem]

In order to achieve the above object, the decorative panel of the present invention has a thermosetting resin decorative board with a thickness of 0.2 to 2.0 ms made of merakine resin, diallyl phthalate resin, polyester resin, etc. The decorative panel is made of foamed urethane resin, It is made of synthetic foamed resin such as foamed phenol resin or wood feathers such as Parsa wood, and is laminated and integrated with a cushioning material that is an elastic body that does not have restoring force even when compressed. A curved mold made of a material is pressed onto the thermosetting resin decorative board to obtain the curved decorative panel of the present invention.

〔Example〕

Examples 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 m and a hard urethane resin foam board (3) with a thickness of 8111 g and a foaming ratio of 10 times are placed on a base material (4) such as particle board with a thickness of 15 m. Adhesives such as urethane resin adhesives (5
), they are laminated and integrated as shown in A in FIG.

Next, an aluminum mold (6) having a diameter of 5flR is pressed from above the diallyl phthalate resin decorative board (2) at a temperature of 120°C and a pressure of 5 kyyd to form the diallyl phthalate resin decorative board (2). and the hard urethane resin foam board (3) are laminated and integrated to produce a decorative panel of the present invention having a curved surface of 5 square radius. Furthermore, as shown in FIG. 2C, the decorative panel (referring to FIG. It can also be used as a panel.

The foaming ratio of the hard urethane resin foam board is 6 to 1.
It is desirable that the magnification is about 5 times; if the magnification is low, embossing will be impossible, whereas if the magnification is high, dents will occur even with the pressure applied with a finger, which is undesirable.

The decorative panel (1) can be 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. used.

〔Effect 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 as in postform processing, and it is not necessary to prepare various types of core materials processed into curved shapes as in postform processing, and it is not necessary to prepare core materials of various types that are processed into curved shapes as in postform processing. There is no need to prepare a gold star. 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 wear resistance, stain resistance, scratch hardness, etc., so it can be used as a decorative material 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.
