[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, when a wallpaper is stuck to an interior wall surface with a starch-based adhesive, a base paper having a surface that is familiar with the starch-based adhesive is applied to the entire interior wall surface with the adhesive. Or is a wallpaper construction method to be pasted in part, on the back side of the lower sticking paper to be attached to the interior wall surface,
Even if it is a wall surface that has not been able to obtain sufficient adhesive strength due to the unevenness of the entire base, which had to be putty coated in the past because many fibers were exposed in a standing shape
It is possible to obtain a base on which wallpaper can be attached by a simple attaching operation.

That is, even if the wall has irregularities on the entire base, such as Juraku Wall, and it has been necessary to stick the wallpaper after applying the putty, the back of the underlay paper (the base wall) If many fibers are exposed on the side surface), the sticky fibers will be entangled with the unevenness of the base when attaching the base paper to this uneven base with adhesive.
Sufficient adhesive strength can be obtained, and a base enough for sticking a wallpaper similar to that of the conventional putty coating can be obtained by a simple sticking operation of the underlining paper.

The underlaying paper of the present invention may be any paper as long as a large number of fibers are exposed on the back surface in a standing manner. As a preferred embodiment, a nonwoven fabric, a woven fabric, a fibrous sheet in which a large number of fibers from a cloth substrate typified by a knitted fabric are exposed in a fluffy state on the back surface to be attached to the interior wall surface as a base paper. Used. This fibrous sheet only needs to be at least on the back surface attached to the interior wall surface. Therefore, as underlay paper,
The above-mentioned fibrous sheet may be used alone, or may have a two or more-layer structure in which a paper or cloth base material or the like that is familiar with a starch-based adhesive used for sticking a wallpaper to the surface side is laminated.

As a cloth base material constituting the fibrous sheet,
For example, a woven fabric or a non-woven fabric in which fibers are plain weave, satin weave, twill weave, satin weave, saori, garami weave and the like are used. In particular, a wool weave, a cloth having the above-mentioned cloth raised, a towel cloth, or the like is preferably used. Further, a sheet obtained by planting a fiber bundle obtained by bundling fine fibers on a sheet of a synthetic resin or the like and raising the fiber is also used. The fiber used is not particularly limited as long as it is entangled with the unevenness of the underlying wall surface. For example, it is selected from natural fibers such as cotton, silk, hemp, wool, and the like, synthetic fibers such as rayon, acetate, and nylon, and inorganic fibers such as talc, rock wool, glass fiber, and asbestos.

The density of the fibrous sheet portion is as follows:
When it is 0.1 g / cm ³ or more, good adhesive strength is maintained. If it is less than 0.1 g / cm ³ , even if it is entangled with the unevenness of the underlying wall surface, the entanglement is fragile and sufficient adhesive strength cannot be obtained. The upper limit differs depending on at least the fineness of the fibers and the distribution of the fibers enough to be entangled with the base unevenness.

As the adhesive used in the present invention, any adhesive may be used as long as it is dried and hardened together with the fibers entangled with the irregularities of the underlying wall surface to obtain a strong adhesive force. For example, a starch-based adhesive alone may be used, but an aqueous synthetic resin-based adhesive is preferably mixed with the adhesive to enhance the dry curing power. As an aqueous synthetic resin adhesive,
An aqueous synthetic resin adhesive that can be mixed with the starch adhesive is selected. For example, vinyl acetate-acrylic copolymer adhesive, ethylene-vinyl acetate copolymer adhesive, SBR latex adhesive,
Aqueous urethane adhesive, aqueous epoxy adhesive,
(All) acrylic adhesives and the like can be mentioned. The aqueous synthetic resin-based adhesive may be used alone, but is expensive.
In addition, a fragile wall such as a flexible wall may be added with an agent for enhancing the sealer effect to these adhesives.

According to another aspect of the present invention, when a wallpaper is adhered to an interior wall surface with a starch-based adhesive, a base paper having a surface that is familiar with the starch-based adhesive is applied to the entire surface of the interior wall surface with the adhesive. It is a wallpaper construction method to be pasted on a part in advance,
As the underlaying paper, a sheet provided with a sponge layer in which a large number of holes are exposed on the back surface to be adhered to the interior wall surface is used. Even on a wall surface having a whole unevenness and a sufficient adhesive strength cannot be obtained, it is possible to obtain a base on which wallpaper can be stuck by a simple sticking operation.

That is, even if it is a wall surface such as a jerak wall which has irregularities on the entire base and has conventionally had to be pasted with putty and pasted with a wallpaper, the back surface of the base paper (the base wall surface) Since a sheet with a sponge layer with many holes exposed on the side) is used, a sponge layer with many holes exposed when attaching the base paper to this uneven base with an adhesive Can get enough adhesive strength because it gets caught in the unevenness of the base and holds the adhesive on itself. A sufficient base can be obtained.

The underlaying paper of the present invention may be any one provided with a sponge layer having a large number of exposed holes on the back surface attached to the interior wall surface. Therefore, as underlay paper,
The sponge layer may be used alone, or may be configured as two or more layers in which a paper or cloth base material or the like that is familiar with a starch-based adhesive used for attaching wallpaper to the surface side is laminated. In a preferred embodiment, when the density of the sponge layer is 0.1 g / cm ³ or more, good adhesive strength is maintained. 0.1 g / cm ³
If it is less than 30, the sponge layer itself becomes fragile, and a sufficient adhesive strength cannot be obtained. The upper limit is different depending on the size and distribution of the holes that are caught at least by the irregularities of the base and that hold the adhesive therein.

As the adhesive used in the present invention, any adhesive can be used as long as it can be stuck to the unevenness of the wall surface of the base, penetrate into the sponge layer, dry and harden to obtain a strong adhesive force. For example, a starch-based adhesive alone may be used, but an aqueous synthetic resin-based adhesive is preferably mixed with the adhesive to enhance the dry curing power. As the aqueous synthetic resin adhesive, an aqueous synthetic resin adhesive that can be mixed with the starch adhesive is selected. For example, vinyl acetate-acrylic copolymer adhesive, ethylene-vinyl acetate copolymer adhesive, SB
Examples include an R latex type adhesive, an aqueous urethane type adhesive, an aqueous epoxy type adhesive, and an (all) acrylic type adhesive. The aqueous synthetic resin-based adhesive may be used alone, but is expensive. In addition, a fragile wall such as a flexible wall may be added with an agent for enhancing the sealer effect to these adhesives.

According to another aspect of the present invention, one or more of a rust inhibitor, a blocking agent, a fungicide, an antibacterial agent, a preservative, or an adsorbent for volatile substances is previously added to the underlaying paper. A method of impregnation is also disclosed. Accordingly, it is possible to prevent the leaching of the acne from the base wall surface, the generation of mold and the like, and the volatilization of volatile substances.

Still another aspect of the present invention is a base paper used in the above-mentioned wallpaper construction method. That is, at least on the back surface adhered to the interior wall surface, underlaying paper in which a large number of fibers are exposed in an upright manner, and on the back surface adhered to the interior wall surface, a sponge layer in which a large number of holes are exposed. It is an underlay paper with.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view showing an embodiment of an underlaying paper used in the wallpaper construction method of the present invention. Fig. a is a cross-sectional view of a two-layer fiber sheet a, Fig. b is a cross-sectional view of a single-layer fiber sheet b, Fig. c is a cross-sectional view of a two-layer sponge sheet c, and Fig. d is a cross-sectional view of a single-layer sponge sheet d.

As shown in FIG. 2A, the fiber sheet a has paper (or a cloth substrate) 11a which is familiar with the starch-based adhesive as a front surface, and a large number of fibers are exposed on the back surface in a standing state. The fibrous sheet 12a is stuck. Also,
As shown in Fig. b, the fiber sheet b is a cloth base material 1 in which fibers are woven.
1b is a front surface, and a large number of fibers are erected on the back surface to expose the erected layer 12b.

[0029] As shown in Fig. C, the sponge sheet c is paper (or a cloth substrate) 11 which is familiar with the starch-based adhesive.
The sponge layer 12c having a large number of holes exposed on the rear surface is attached to the rear surface of the sponge layer 12c. Further, as shown in Fig. D, the sponge sheet d is a single sponge layer 12d in which many holes are exposed. Wallpaper is adhered to the front surface with a starch-based adhesive, and adhered to the base wall surface with an adhesive on the back surface.

FIG. 2 is a schematic view showing the state of adhesion between the underlaying paper and the base wall by the wallpaper application method of the present invention. As shown in Fig. a, the fibrous sheet 12a on the back surface of the fibrous sheet a is entangled with the irregularities of the base wall surface 21a, and the adhesive 22a fills and penetrates therebetween, and is dried and cured to obtain a sufficient adhesive force. Further, as shown in Fig. B, the sponge layer 12c on the back surface of the sponge sheet c is hooked on the unevenness of the base wall surface 21b, and the adhesive 22b penetrates into the unevenness and the sponge layer 12c and is dried and hardened to obtain a sufficient adhesive force.

The adhesive strength on the wall foundation was measured. More specifically, when pasting wallpaper on the wall base, if the base paper that is familiar with the starch-based adhesive is applied to the entire base in advance, the base paper itself is entangled with the base unevenness because the wall irregularities are large. This leads to improved adhesive strength. Therefore, various sheets are applied to the base surface of the wall with a synthetic resin-based adhesive (synthetic resin emulsion-based adhesive (density of 35).
%), Applied at 300 g / cm ² ), dried,
The adhesive strength was measured by a 180 degree peel test. In addition, the sticking force was measured in the same manner even when the base wall surface was subjected to a sealer treatment using a solvent-based sealer. The results are shown in Table 1 below.

[0032]

[Table 1]

As shown in Table 1, the fiber sheet a of the present embodiment
(3) In woven fabric + paper, the other (1)
Compared with plain paper and (2) nonwoven fabric, an overwhelming increase in adhesive strength was obtained. In addition, it was confirmed that even when the sealer was not treated, a sufficient adhesive force was obtained, which was at least twice as large as that obtained by performing the sealer treatment of another example.

[0034]

As described above, according to the present invention, a simple sticking operation can be performed even on a wall surface which cannot obtain a sufficient adhesive force due to the unevenness of the entire substrate, which has conventionally been forced to be putty-coated. Thus, there is an effect that a base on which wallpaper can be attached can be obtained.
