[Problems to be solved by the invention]
However, when applying a decorative sheet to a site having a complicated shape, for example, a connection portion between a tread plate and a riser of a spiral staircase, the size is measured in advance with a pattern according to the shape of the above-mentioned portion, and the shape is the same as the shape. Dimensions, the same size cut decorative sheet must be reapplied. Therefore, the above-mentioned construction method has a problem that it is troublesome and requires skill. The present invention has been made in order to solve such a problem, and it is possible to perform work with good workability even in a part having a complicated shape inside a house, various buildings, etc., and is particularly suitable for renovation. It is an object of the present invention to provide a decorative sheet and a method for constructing the same.
[0005]
[Means for Solving the Problems]
The present invention has been conceived in order to solve the above problems, and employs the following technical means. That is, according to the first invention of the present application, the protective sheet, the base sheet, and the release paper are laminated in this order, and the first pressure-sensitive adhesive layer having low adhesive strength is provided between the protective sheet and the base sheet. There is provided a decorative sheet in which a second pressure-sensitive adhesive layer having strong adhesive force is interposed between the base sheet and the release paper. By doing so, it is possible to obtain a decorative sheet that can be neatly applied without gaps even in a portion having a complicated shape.
[0006]
It is preferable that the first pressure-sensitive adhesive layer has excellent adhesion to the protective sheet and is easily peeled from the base sheet. By doing so, the protective sheet can be peeled off from the base sheet and used as a mold sheet. Even in a construction site having a complicated shape, the protective sheet can be used as a mold sheet and easily molded. be able to.
[0007]
The first pressure-sensitive adhesive layer can be easily peeled off from the base sheet and can be re-adhered to the base sheet. If the mold sheet molded at the construction site having a complicated shape as described above is re-adhered to the base sheet, it can be easily molded according to the mold of the mold sheet.
[0008]
The base sheet is preferably a veneer sheet having a wood grain pattern on the surface. When constructing a complicated part with a wood grain pattern, such as a tread of a spiral staircase, a veneer sheet molded as described above is used as a base material sheet, and is adhered via a second adhesive layer. It is possible to apply the wood grain pattern neatly without any gaps.
[0009]
Further, according to the second invention of the present application, the protective sheet, the base sheet and the release paper are laminated in this order, and the first pressure-sensitive adhesive layer having low adhesive strength is provided between the protective sheet and the base sheet. A decorative sheet having a second adhesive layer having a strong adhesive force interposed between the base sheet and the release paper is used. First, the protective sheet that has been peeled off is used as a mold sheet to form a mold on the construction site. Then, after the mold sheet after the mold is re-adhered to the base sheet, cut according to the mold, the cut decorative sheet, the release paper is peeled off and attached to a construction site. The present invention provides a method for applying a decorative sheet. In this manner, a method for applying a decorative sheet, which can be applied neatly without gaps even in a portion having a complicated shape, is provided.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings. FIG. 1 is an explanatory view showing the configuration of the decorative sheet according to the first invention of the present application from the side. As shown in FIG. 1, the decorative sheet A has a protective sheet 1, a base sheet 3, and a release paper 5 sequentially laminated from above through a first adhesive layer 2 and a second adhesive layer 4. ing. At this time, the base material sheet 3 is composed of, for example, a decorative film 31 on which a pattern such as wood grain is printed and a base material 32. If the base material 32 is flexible, the base material sheet 3 is in a roll shape. Served as a fixed sheet.
[0011]
The protective sheet 1 is made of a transparent or translucent material, and a biaxially stretched plastic film is preferably used. Among them, a biaxially stretched polypropylene film (OP) is preferably used because it is excellent in transparency, strength, water resistance and the like. The first pressure-sensitive adhesive forming the first pressure-sensitive adhesive layer 2 is a pressure-sensitive adhesive of acrylic, rubber, polyurethane, silicone, or the like. Is selected from pressure-sensitive adhesives prepared so as to have high affinity.
[0012]
As the base sheet 3, a decorative film 31 such as a soft polyvinyl chloride film, a polyethylene terephthalate, a polybutylene terephthalate, or a polypropylene on which a grain pattern or the like is printed on a back surface, and a base such as a flexible member such as a plastic sheet or a plywood. What is attached to the material 32 is used. As the second pressure-sensitive adhesive forming the second pressure-sensitive adhesive layer 4, a rosin-based resin, a terpene-based resin, a xylene-based resin, an isoprene resin, a petroleum-based resin, or the like can be appropriately used as long as it exhibits strong adhesion at room temperature. It is possible. As the release paper 5, for example, a known release paper coated with a silicone release agent can be used.
[0013]
Next, a method for applying the decorative sheet A according to the second invention of the present application will be described with reference to examples. The present embodiment is an example in which the decorative sheet A according to the first invention of the present application configured as shown in FIG. 1 is applied to a case where a tread of a spiral staircase is reformed. FIG. 2 shows a veneer sheet obtained by affixing a decorative film 31 having a woodgrain pattern printed on the back thereof to a plywood 32 as a base sheet 3, and a first adhesive layer 2 on the upper surface of the veneer sheet. FIG. 4 is an explanatory view showing a state in which a transparent protective sheet 1 that has been adhered is peeled off.
[0014]
As shown in FIG. 2, the protective sheet 1 is peeled off together with the first pressure-sensitive adhesive layer 2 and used as a mold sheet 6. That is, as shown in FIG. 3, the peeled protective sheet 1 is adhered to a tread portion of a spiral staircase and used as a mold sheet 6. After the molding, the molded mold sheet 6 is peeled off from the work site and is again adhered to the veneer sheet. After the reattachment, as shown in FIG. 4, if the veneer sheet is cut together with the release paper 5 according to the shape of the mold sheet 6, a decorative sheet B exactly fitted to the shape of the construction site is obtained. Thereafter, the release paper 5 is finally peeled off, adhered to the construction site of the tread plate so as to have no gap, and then pressed and cured by a known method. Thus, the construction site and the veneer sheet are strongly adhered to each other via the second pressure-sensitive adhesive layer 4, so that a wood-grained decorative sheet can be constructed neatly without gaps.
[0015]
