[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative panel construction method and a V-cut decorative panel used for the method. More specifically, according to the present invention, since there is no generation of chlorine gas or the like at the time of incineration, there is no problem of disposal, and a decorative panel using a specific base sheet excellent in chip processing is subjected to V-cut processing, and the panel is mounted. The present invention relates to a method of applying a decorative panel to be attached to a body, and a V-cut decorative panel which is excellent in V-cut workability and has no disposal problem.

[0002]

2. Description of the Related Art Conventionally, surface decorative boards such as cabinets for furniture, kitchen products, and electric appliances are generally used for bonding materials such as wood-based materials, inorganic materials, and metal-based materials such as steel plates. A structure in which a decorative sheet on which a pattern or the like is printed is attached with an adhesive is used. The surface decorative board obtained in this way is further subjected to a bendable processing such as V-cut processing, so that the decorative sheet is on the front side according to the outline of furniture, kitchen products, cabinets of electric appliances and the like. Bent and mounted. As a decorative sheet used for such a surface decorative plate,
Heretofore, a vinyl chloride resin sheet has been generally used because it has moderate flexibility and good workability such as V-cut workability and lapping workability. However, this vinyl chloride resin sheet is durable (wear,
Resistance to scratching, dents, etc.) and cleaning (easy cleaning,
(Wax applicability, antifouling property, antibacterial property) is bad, and harmful chlorine and dioxin are generated at the time of incineration. Therefore, there is a problem in terms of environmental pollution, and the plasticizer contained therein bleeds. It also had problems such as easy appearance and poor appearance. In addition, since such a decorative sheet is bonded to a material to be bonded such as a wood-based material using an adhesive to form a surface decorative plate, there is a problem in that it takes time to bond the decorative sheet. Therefore, when V-cut processing is performed without using a vinyl chloride resin, it is not damaged even when bent, has good bending workability, and is excellent in durability and cleanability. There has been a demand for a decorative board that does not need to be bonded. By the way, when V-cut processing is performed on a decorative board in which a decorative sheet is bonded to such a wooden material as described above, the hinge effect (hinge effect) is not provided because the base material such as the wooden material is not flexible. To make full use, the V-cut must be applied to the depth reaching the decorative sheet, and as a result, the decorative sheet is often cut off. Therefore, it is important to perform V-cut processing so that such inconvenience does not occur.

[0003]

Under such circumstances, the present invention does not generate chlorine gas or the like at the time of incineration.
There is no problem of disposal, and there is no need to attach to the material to be attached such as wood-based material, and the decorative film layer provided on the surface is used by using a decorative panel using a base sheet excellent in cutting workability. The decorative panel is subjected to V-cut processing by means that is less likely to be cut, and is applied to a cabinet of furniture, a kitchen product, and an electric product. The purpose of the present invention is to provide a V-cut decorative panel free from the above problems.

BEST MODE FOR CARRYING OUT THE INVENTION A decorative panel used in the method for constructing a decorative panel according to the present invention is provided on one side of a base sheet.
On one side of a decorative panel or a base sheet in which a picture layer, a transparent plastic film layer and a clear coat layer are sequentially laminated, or a colored polypropylene resin film layer, a picture layer, a transparent plastic film layer and a clear coat layer as the case may be. It is a decorative panel sequentially laminated | stacked, As said base sheet, inorganic filler 30-80
A sheet made of a polypropylene-based resin containing 10% by weight is used. The polypropylene resin used for the base sheet is not particularly limited, but is, for example, an isotactic propylene homopolymer having crystallinity, an ethylene-propylene random copolymer having a low ethylene unit content, or a propylene homopolymer. A propylene block copolymer composed of a homo part consisting of and a copolymer part consisting of a relatively large ethylene-propylene random copolymer having a relatively high content of ethylene units, and further each homo part in the propylene block copolymer or A crystalline propylene-ethylene-α-olefin copolymer or the like in which the copolymerization portion is further obtained by copolymerizing an α-olefin such as butene-1 is exemplified. The melt index of these polypropylene resins (measured at 230 ° C. and 2.16 kgf) is not particularly limited, but is preferably from 0.3 to 13.0 g / 1.
0 minute, more preferably in the range of 0.5 to 8.0 g / 10 minutes. This polypropylene-based resin may be used alone, or two or more kinds may be used in combination.
A soft polypropylene resin may be blended with the above-mentioned crystalline polypropylene resin at an appropriate ratio and used. On the other hand, as the inorganic filler used in the base sheet, for example, calcium carbonate, magnesium carbonate, aluminum hydroxide, magnesium hydroxide, kaolin, silica, perlite, calcium sulfate, barium sulfate, calcined alumina, calcium silicate, talc, Mica and the like may be used, and these may be used alone or in combination of two or more. Among these inorganic fillers, calcium carbonate is particularly preferable from the viewpoint of machinability and the like.

In the present invention, the content of the inorganic filler is important from the viewpoint of the machinability since V-cutting is performed as described later. If the content of the inorganic filler is less than 30% by weight, the machinability is poor, and the V-cut portion cannot be formed well. On the other hand, if it exceeds 80% by weight, sheet formability and impact resistance are reduced, and the weight is increased. In consideration of cutting workability, sheet formability, impact resistance, light weight, and the like, the preferred content of the inorganic filler is in the range of 40 to 70% by weight, particularly 50 to 6% by weight.
