DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative sheet used for surface finishing such as interior decoration of buildings, surface decoration of fittings, interior decoration of vehicles and the like. The present invention relates to a recoating decorative sheet used for coloring the surface of a product to an arbitrary color using a coloring paint.

[0002]

2. Description of the Related Art Conventionally, as a decorative sheet used as a surface decoration material for interiors such as walls and ceilings of buildings, furniture, cabinets and the like, a polyvinyl chloride sheet is often used as a base sheet. For example, there are a sheet in which a grain pattern or the like is printed on a polyvinyl chloride sheet and a transparent polyvinyl chloride sheet is laminated on the sheet pattern, and a sheet in which a transparent polyvinyl chloride sheet is embossed. As a substitute for the polyvinyl chloride sheet, a decorative sheet using a polyolefin resin sheet such as polyethylene or polypropylene has been proposed.

Conventionally, there are two types of decorative sheets: those which are already colored, and those which have not been colored and are subsequently coated with a coloring agent such as stain. The latter is re-coated (recoated). It is called a decorative sheet. Here, "stain" (stain in English) is a coloring agent for coloring the surface of wood, and is used in the form of liquid, gel, spray or the like. It was added to. There are an aqueous type and an oil type, and in Japan they are called oil stain, stain varnish, aqueous stain and the like.

[0004] Since the decorative sheet for recoating is a non-colored decorative sheet, when a decorative material obtained by laminating this decorative sheet on the base material surface is used, after the decorative material is assembled into a product, a colored paint such as stain is applied to the product. Since it is applied to the decorative sheet on the surface, it is easy to color the product to any color.
According to this method, the surface is not damaged at the time of assembling the product, the coloring does not come off, the workability is good, and the occurrence of defective products can be prevented. In addition, to a colorless product assembled in advance,
Since necessary coloring can be performed according to demand, there are various advantages such as easy management of product inventory.

[0005] Conventional decorative sheets for recoating are, for example, disclosed in Japanese Patent Application Laid-Open No. 60-149457, on a cellulose-based substrate sheet as a printing substrate.
It is known that a pattern layer is provided using a printing ink using a cellulosic resin as a vehicle, and a paint containing a polyol component, an isocyanate component, and a cellulosic component is applied thereon. This decorative sheet for recoating has good durability, prevents penetration of the resin of the recoating paint, has a good finish, and has high adhesion to the recoating paint.

[0006]

However, in the case of a decorative sheet in which a resin layer is simply formed on the surface, such as the above-mentioned decorative sheet, even if the adhesiveness with the recoating paint is good, the surface is hardly damaged. Since it is formed smoothly, the recoating paint does not penetrate into the inside of the surface resin layer, and drips even if it is applied with a thick stain or the like, and it is difficult to obtain a surface with excellent feeling of holding. For example, colored PVC sheet /
In the case of a pattern layer / transparent PVC sheet (surface), a colored PVC sheet / pattern layer / OP layer (surface), and a decorative paper / pattern layer / OP layer (surface), the surface is a resin layer. It is difficult to form a thick coating film. still,
The above PVC means polyvinyl chloride, OP means overprint, and the same applies hereinafter. The present invention is to solve the above disadvantages of the prior art, by using a non-woven fabric on the surface of the decorative sheet for recoat,
This makes it possible to apply a recoating paint such as stain thickly, and to form a surface with excellent feeling of holding.

[0007]

In order to solve the above problems, a decorative sheet for recoating has the following structure. In a decorative sheet for recoating in which a nonwoven fabric and a pattern layer are laminated on a thermoplastic resin sheet, the nonwoven fabric is adhered to the thermoplastic resin sheet via an adhesive, and a pattern layer is formed on the nonwoven fabric. A decorative sheet for recoating, characterized in that: Further, in a decorative sheet for recoating in which a nonwoven fabric and a pattern layer are laminated on a thermoplastic resin sheet, the nonwoven fabric is laminated by being thermally fused to the thermoplastic resin sheet, and a pattern layer is formed on the nonwoven fabric. Decorative sheet for recoating. Further, the pattern layer is a gravure-printed pattern layer using an ink containing a two-part curable resin as a binder, and, when a colored paint such as stain is applied on the pattern layer, the pattern layer A decorative sheet for recoating, characterized in that it is a picture layer that produces contrast depending on the presence or absence.

That is, a nonwoven fabric is laminated on a PVC sheet by an adhesive or heat fusion, and a pattern layer such as a grain is printed on the nonwoven fabric by gravure printing to form a decorative sheet for recoating. And, by using a two-component curable resin as a binder as the ink for the pattern layer, even if the amount of application of the printed portion is small, when a colored paint such as stain is applied on the decorative sheet, the portion with the pattern layer and the The contrast of the portion without the picture layer is made clear.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is an example of a decorative sheet for recoating of the present invention, and is a schematic longitudinal sectional view when a base sheet and a nonwoven fabric are laminated with an adhesive. FIG. 2 is a schematic longitudinal sectional view of another embodiment of the decorative sheet for recoating of the present invention, in which a base sheet and a nonwoven fabric are heat-sealed. FIG. 3 is an explanatory diagram for producing a recoating decorative sheet of the present invention. FIG. 4 is an explanatory view when producing a recoating decorative sheet according to the third embodiment. The decorative sheet for recoating of the present invention is shown in FIG.
As shown in the figure, a base sheet 11 and a non-woven fabric 13 are laminated via an adhesive layer 12, a pattern layer 12 is provided on the non-woven fabric to form a decorative sheet for recoating, and a colored paint such as stain is applied thickly. It is made possible. FIG.
As shown in the figure, when the base sheet 11 and the nonwoven fabric 13 are laminated, the base sheet 11 and the nonwoven fabric 1 are not used without using an adhesive.
In some cases, the decorative sheet 3 is heat-sealed and laminated, and the pattern layer 12 is provided on the nonwoven fabric to form the decorative sheet 1 for recoating.

The decorative sheet for recoating according to the present invention uses a nonwoven fabric on the surface, so that when a paint for recoating such as stain is applied, the nonwoven fabric of the decorative sheet for recoating becomes
The paint is reliably held in the voids, and the paint is prevented from dripping from the surface of the decorative sheet, so that a recoat layer having excellent feeling of holding can be obtained. In addition, the decorative sheet 1 for recoating of the present invention has a pattern layer formed on the surface of a nonwoven fabric using a gravure ink made of a two-part curable resin, and a paint layer for recoating, such as stain, is applied thereon. The contrast is made clear by the presence or absence of the decorative sheet, and the design of the decorative sheet is enhanced.

The following is an example of a method for producing the decorative sheet for recoating of the present invention. First, as shown in FIG. 3A, a gravure printing is performed on one surface of the nonwoven fabric 13 using a two-component curing type ink to form a pattern layer 14 such as a wood grain pattern. On the other hand, using a colored PVC sheet 11a as a base sheet, as shown in FIG.
An adhesive is applied on 1a to form an adhesive layer 12.
Next, as shown in FIG. 3 (c), the nonwoven fabric 13 side of the nonwoven fabric 13 on which the picture layer 14 is formed is laminated on the adhesive layer 12 of the colored PVC sheet 11a to produce the decorative sheet 1 for recoating. . Since the nonwoven fabric 13 is used on the surface of the obtained decorative sheet for recoating, when a paint for recoating such as stain is applied, the nonwoven fabric on the surface becomes
The paint can be reliably held in the voids, and a recoat layer having an excellent feeling of holding can be obtained. In addition, since the two-component curing type ink is used as the ink for the pattern layer, when the recoating paint such as stain is applied, the stain hardly penetrates into the ink portion of the pattern layer, and the ink of the pattern layer becomes Since it does not penetrate into the non-woven fabric, the contrast becomes clear depending on the presence or absence of the picture layer even by coloring the surface, and the design property is enhanced. Further, when wax is added to the two-part curable ink, the picture portion completely repels stain, so that the contrast with the portion where there is no ink is increased and the effect is enhanced.

An embossed pattern can also be formed on the surface of the decorative sheet for recoating by a known method.
That is, the embossed pattern is formed on the surface of the nonwoven fabric by heating and pressing using an embossed roll having an embossed pattern such as a wood grain conduit. In addition, when the base sheet and the nonwoven fabric having the pattern layer formed thereon are heat-sealed, the base sheet and the nonwoven fabric can be heat-sealed using an embossing roll, and an embossed pattern can be formed on the surface of the nonwoven fabric. . Further, the embossed concave portions may be filled with a coloring ink by wiping to obtain a decorative sheet for recoating.

As the nonwoven fabric used in the decorative sheet for recoating of the present invention, synthetic fibers, natural fibers, glass fibers, etc. are formed into a mat or a thin cotton by an appropriate method, and the fibers are bonded to each other by an adhesive or the fusion force of the fibers themselves. The sheet-like thing made by joining is used. The nonwoven fabric has an advantage that any fiber can be used as a raw material fiber, and short fibers that cannot be spun can be used. Non-woven fabrics can be manufactured by wet methods, dry methods,
Although there is a direct method and the properties of the nonwoven fabric differ depending on the production method, the nonwoven fabric used in the present invention may be made by any method. However, in the present invention, since printing is performed on a nonwoven fabric, those made by a wet method are preferable. It is difficult to obtain a fine-grained printed pattern with a nonwoven fabric manufactured by a dry method or a spun bond method (direct method).

[0014] Since all nonwoven fabrics are made by forming a web and bonding the web, the method of forming the web gives a nonwoven fabric (oriented nonwoven fabric) in which the fibers are arranged in a certain direction and the orientation of the fibers. Non-woven fabric (non-oriented non-woven fabric) is obtained. In addition, since the non-oriented nonwoven fabric has a resistance to tearing because the direction of the fiber is randomly formed, the non-oriented nonwoven fabric may be laminated on the oriented nonwoven fabric to improve the overall strength. is there. The laminated nonwoven fabric is not limited to a laminate of an oriented nonwoven fabric and a non-oriented nonwoven fabric, but may be used by laminating oriented nonwoven fabrics so that their orientation directions cross each other and improving the reduction in tear strength in the orientation direction. When a nonwoven fabric obtained by laminating an oriented nonwoven fabric and a non-oriented nonwoven fabric is used for the decorative sheet for recoating of the present invention, either of the nonwoven fabrics may be used as the surface side, but the oriented nonwoven fabric is used for brushing a colored paint such as stain or for lapping. It has the effect of suppressing fluff at the time. But,
The oriented nonwoven fabric has a difficulty in printing a fine-grained pattern. Therefore, when emphasizing the pattern layer, it is preferable to use a nonoriented nonwoven fabric on the surface.

[0015] The method of bonding the fibers in the production of the non-woven fabric includes a method using an adhesive, a method of thermally fusing the fibers, a dip bonding method, a mechanical bonding method, and the like. As the adhesive, a vinyl chloride emulsion, a vinyl acetate emulsion, an acrylate ester emulsion or a copolymer emulsion of these are mainly used, and a method of spraying on a web by spraying, a method of dipping, a foaming and press-fitting the web are used. And the like.

The fiber used for the non-woven fabric is, in the case of short fibers, one of natural fibers such as cotton, synthetic fibers such as rayon, acetate, nylon, vinylon, polyester, polyolefin, and acrylic, glass fibers, and the like. A mixture of two or more of these various fibers is used. In the present invention, those using polyester fibers are preferable from the viewpoint of water resistance and solvent resistance. Polyolefin such as polyester, nylon, polypropylene, and polyethylene, polyvinyl chloride, and the like are used for melt spinning in the spun bond method. In the case of the wet method, cellulose rayon is used. When the material of the fiber is acrylic, rayon, nylon, polyolefin, or the like, the nonwoven fabric can be bonded to the substrate sheet by heat fusion. In addition, when a nonwoven fabric that is a mixture of acrylic fiber and polyester fiber is used, when the surface of the decorative sheet for recoating is coated with stain, it is possible to prevent the fibers of the nonwoven fabric from fluffing due to brushing. The product surface afterwards becomes excellent in appearance.

As shown in FIG. 1, the pattern layer 12 is formed on the nonwoven fabric 13 by printing and then laminated on the base sheet 11, so that the nonwoven fabric 13 is not particularly limited as long as it can be printed and laminated. But the basis weight is 10-1
A range of 00 g / m ² is preferred. A nonwoven fabric having a basis weight of less than 10 g / m ² may have an insufficient feeling of holding when coating with a coloring agent, and may have insufficient surface durability. or,
When the basis weight of the nonwoven fabric is 100 g / m ² or more, the amount of the coloring agent retained when coating with a coloring agent such as stain becomes too large, which may impair the transparency of the surface and make the picture pattern invisible. There is.

As the substrate sheet used in the present invention, any material used as a substrate of the decorative sheet, for example, paper, plastic, metal foil and the like can be used. The substrate sheet used in the present invention is preferably a sheet-shaped sheet such as paper, plastic, metal foil or the like, which is flexible because it can be continuously produced in a wound state in a manufacturing process.

It is preferable that the content be 5% by weight or less.

In selecting a monomer, if the flexibility of the cured product is required, the amount of the monomer may be reduced within a range that does not impair coating suitability, or a monofunctional or bifunctional acrylate monomer may be used. A structure having a relatively low crosslink density is used. In addition, when the heat resistance, hardness, solvent resistance, etc. of the cured product are required, the amount of the monomer may be increased within a range that does not hinder coating suitability,
It is preferable to use a tri- or more functional acrylate-based monomer to obtain a structure having a high crosslinking density.
