Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper having a peeling layer mainly used for a wall of an exhibition hall, a model house, etc., and a method of manufacturing the same.

[0002]

2. Description of the Related Art In recent years, various types of wallpaper have been used in new construction of houses, renovation of rooms, remodeling, etc. due to demands such as shortening of construction work, cost reduction, and easy change of living environment. As one of these typical wallpapers, on one side of the wallpaper layer, a decorative layer mainly using vinyl chloride resin or foam resin,
Wallpaper having a configuration in which only one adhesive layer is provided on another side or a release layer is overlaid on the adhesive layer, and the surface of the adhesive layer is stuck to a wall surface is well known.

[0003] The above-mentioned known wallpaper uses not only the problem of generation of dioxin at the time of incineration disposal due to the use of vinyl chloride resin, but also the adhesive layer when the wallpaper is to be peeled off from the wall surface during indoor renovation or remodeling. If the wallpaper layer is partially peeled off, leaving uneven wall surfaces, or if the decorative layer has poor tensile strength,
Since the wallpaper layer itself is also inferior in strength, it was difficult to peel off the wallpaper from the wall surface, and it was not expected that the wallpaper could be easily replaced.

[0004] In order to solve such problems, an inorganic paper containing pulp and a water-inorganic compound containing crystallization, wherein a wallpaper layer containing a specific ratio of the inorganic compound containing water in crystallization to the weight of the inorganic paper is used. On one surface, a release agent layer having a specific ratio of an inorganic compound and a sticky organic binder is laminated, and the peeling force when bonded to the gypsum board wall surface is a wallpaper having a strength within a certain range in the folded peeling. Invented, patent 2
No. 864200 in the patent gazette and is known.

[0005]

SUMMARY OF THE INVENTION The above patent invention is a wallpaper used on a gypsum board wall surface, which is often used for a ceiling and an inner wall of a building, as one of the building materials having excellent fire and antiseptic properties. Because the board is inferior in water resistance and impact resistance, the wallpaper itself must have many specific conditions, the wallpaper can be easily peeled off, but the release agent layer must remain as it is, Because it is limited to gypsum board, plasterboard wall surface of newly built house, indoor renovation that is gypsum board wall surface,
It is optimal for applications such as pattern change.

However, the wallpaper used in the case where the wall is not gypsum board or where the frequency of wallpaper replacement is high, such as an exhibition hall or a model house where the cost is high, is based on the use of the wallpaper according to the patented invention. It is difficult to expect the effect.

That is, when the wall is not gypsum board,
The wallpaper according to the patented invention is difficult to adapt to distortion (including expansion and contraction) due to room conditions such as temperature and humidity to which the wall surface is exposed, and it is difficult to change the wallpaper regardless of the wall to be stuck. Every time the release agent layer remains as it is and is laminated, the thickness of the release agent layer increases even if it is so thin, and partially smooth irregularities are formed at an early stage. It is visually recognized by reflection or the like, and impairs the design appearance of the re-covered wallpaper surface.

[0008] For these reasons, the wallpaper according to the patent invention is hardly a welcomed optimal wallpaper both in cost and as a wallpaper for a specific use.

The present invention is inexpensive without being limited to wall materials, and is not limited to wall materials, and is not limited to gypsum board, and is particularly important as a wallpaper used for walls of exhibition rooms and model houses, etc. It is an object to provide a wallpaper capable of maintaining the most important design appearance and a method for producing the wallpaper.

[0010]

(1) In the wallpaper with a release layer in which the release layer (3) of the thin film alone or the release layer (3) and the glue layer for wall surface adhesion (5) are integrally laminated, the release layer (3) may be polyvinyl. It consists of a mixture of alcohol solution, dispersant, T clay and water / water repellent. When the wallpaper layer (1) is peeled off, the peeling layer (3) is cleaved and the wallpaper side residue (31) and wall surface side residue (32).

[0011]

According to the wallpaper having a release layer according to the first aspect of the present invention, the release layer (3) of the thin film formed on the back surface of the wallpaper layer (1) comprises a polyvinyl alcohol solution, a dispersant,
Because it is the composition which blended T clay and water resistant and water repellent,
The penetrating power of these components to the back surface of the wallpaper layer (1) and the adhesive layer (5) for adhering to the wall surface which is layered integrally with the release layer (3) is ensured.

[0012] For this reason, since the wall surface layer (1) and the release layer (3) and the boundary surface between the release layer (3) and the adhesive layer (5) for wall surface adhesion are formed in a non-separable and integral manner, The pulling force in the turning direction applied when the wallpaper is peeled off acts on the thickness of the peeling layer (3) in a cleavage-like manner along the lamination surface, so that the peeling layer (3) has a remaining amount on the wallpaper side. (31) and remaining on the wall (32)
And it will be divided into two.

Therefore, when the wallpaper layer (1) is peeled off from the wall surface, the remaining portion (31) on the wallpaper side is peeled off together with the wallpaper layer (1), and the surface of the adhesive layer (5) for wall surface adhesion is formed. The remaining portion (32) on the wall side, which is thinner than the release layer (3), remains only in the form of a smooth thin film. It is flat and smooth, so the most important design appearance is hardly affected by the frequency of wallpaper replacement, and the work can be done very easily.
(1) enables the provision of an inexpensive wallpaper with a peeling layer, whose material is not specified and which can be applied to the wallpaper layer (1) of any material selected in common sense.

Further, when the dispersant is a polyoxyethylene / nonylphenyl ether mixture and the water / water repellent is a zirconium compound, the dispersant may be generated in a short time according to the use environment. Also, it prevents moisture, moisture or melted adhesive components from penetrating into the wallpaper layer from the wall surface side, preventing discoloration and deterioration of the wallpaper layer, and maintaining the most important design appearance as the wallpaper. Make it even better.

[0015] Further, as described in claim 3, a wallpaper layer
By forming a water-resistant protective layer (2) on the surface of (1), the penetration of moisture, moisture or dissolved adhesive components from the surface side of the wallpaper layer (1) into the wallpaper layer is prevented, In addition to preventing the penetration of moisture and the like from the wall surface into the wallpaper layer, discoloration and deterioration of the wallpaper layer from both the front and back surfaces are prevented, and the design and appearance important as the wallpaper are further maintained.

[0016] As described in claim 4, the protective layer
As (2), by using a vinyl acetate / acrylate copolymer or / and casein solution and a pH adjuster, inexpensive and excellent water resistance is obtained, and discoloration or the like due to oxidation of the wallpaper layer is prevented.

(Method for producing wallpaper with release layer according to second invention) Next, a method for producing wallpaper with a release layer will be described.
Into water, add a polyoxyethylene / nonylphenyl ether mixture as a dispersant, add T-clay as a pigment with stirring, stir, and then, with stirring, add polyvinyl alcohol in water as an adhesive in advance to reach the optimum temperature. A release layer paint production process in which a polyvinyl alcohol solution prepared by heating and stirring and a zirconium compound as a waterproofing agent are sequentially added and stirred, and the release layer paint produced in the process is applied to the back surface of the wallpaper layer (1). Forming a layer having a constant thickness by a coating means.

In the case where the protective layer (2) is formed on the surface of the wallpaper layer (1) as the release layer-equipped wallpaper, a dispersing medium is used in addition to the release layer paint production step and the release layer formation step. In water, while stirring, sodium hexametaphosphate as a dispersant, ammonia water as a pH adjuster, T-clay and titanium oxide as a pigment, DBP emulsion solution with pH adjusted as a defoamer, casein solution as a waterproofing agent, and vinyl acetate / acrylic A protective layer forming step of applying a protective layer paint obtained by sequentially adding an acid ester copolymer resin is performed.
