布、壁面に対する施工の際の取り扱いが困難となる。The inorganic wallpaper of the present invention has a mode in which a decorative layer is not formed and a mode in which a decorative layer is formed. Those without a decorative layer are usually used by adhering the decorative layer with an adhesive, but those without a decorative layer can be used for the invisible walls such as the ceiling ceiling. The structure of the inorganic wallpaper of the present invention having a decorative layer attached will be described with reference to FIG. A release agent layer 5 that holds the inorganic paper 3 and the adhesive layer 2 in a peelable manner is provided on one surface of the inorganic paper 3 containing an inorganic compound and pulp as main components. The release agent layer 5 is provided by coating the release composition mainly composed of an inorganic compound and an organic binder on the inorganic paper 3, and the release agent layer 5 is preliminarily formed on the adhesive layer 2 or the release layer applied at the time of construction. It is adhered to the refractory base material 1 through the applied rewetting adhesive layer 2. With such a configuration, when the wallpaper is re-applied, the inorganic paper 3 is usually uniformly peeled at the interface AA with the release agent layer 5, and the adhesive layer 2 is formed on the surface of the fire-resistant substrate 1. The release agent layer 5 adhered on the upper surface exposes the smooth surface, and makes it possible to easily and beautifully apply a new inorganic wallpaper or the like. The release agent layer of the present invention has a peel strength of 50 to 500 g / when bonded to a gypsum board.
It is adjusted to 30 mm, preferably 70 to 400 g / 30 mm. The release agent layer 5 has its release strength adjusted by adjusting the type and blending ratio of the organic binder.
It can be selected within the above range according to the thickness and tensile strength of the decorative material layer 4. If this peel strength is less than 50 g / 30 mm, the inorganic wallpaper stuck to the wall may fall off, and if it exceeds 500 g / 30 mm, the removability between the release agent layer and the inorganic wallpaper is significantly reduced. The peel strength of the release agent layer in the present invention is determined by adhering the release agent layer side of the laminate consisting of the inorganic paper and the release agent layer on a gypsum board with a starch paste adhesive and making a cut line of 30 mm width in this inorganic paper. (The release agent layer also has cuts), the tip of this 30 mm wide inorganic paper is folded back in the direction of 180 ° C, and the folded tip is 300 mm / min speed using a universal tensile strength tester. The peeling operation was performed by pulling, and the numerical value obtained by measuring the peeling resistance was defined as the peeling strength value. The gypsum board used in this test is the non-combustible gypsum board of the Building Standards Act (Enforcement Order Article 1-5). The present invention is an inorganic wallpaper in which a decorative layer is laminated as described above. The other surface of the inorganic wallpaper is coated with a composition containing an inorganic compound as a main component and an organic binder and is coated by another method. It is characterized in that an agent layer is formed. This coating amount is, as a surface density, 3 to 30% of the surface density (basis weight) of the inorganic wallpaper, preferably,
It is preferable to apply it at 5 to 25%. When the surface density is less than 3% of the surface density of the inorganic wallpaper, the shielding effect of the adhesive layer disappears, and the layer of the inorganic wallpaper remains on the wall surface at the time of peeling as shown in FIG. lose. If it exceeds 30%, the release agent layer remaining on the wall surface becomes thick and similarly the smoothness of the wall surface is lost. Since the inorganic wallpaper of the present invention can be removed again without depending on the strength of the decorative layer, it can be applied to a wallpaper without a decorative layer. As the crystal water-containing inorganic compound to be added to the inorganic paper used for the inorganic wallpaper of the present invention, for example, aluminum hydroxide, magnesium hydroxide or the like can be used. In particular, aluminum hydroxide is desirable because it has a large amount of crystal water and is excellent in fire prevention performance. The inorganic paper may be used in a proportion of 50 to 90% by weight, preferably 70 to 85% by weight, based on the weight of the paper.
If it is less than 50% by weight, the fireproof property is deteriorated, and if it exceeds 90% by weight, the inorganic wallpaper becomes too brittle, and it becomes difficult to apply the release agent layer and handle it at the time of construction on the wall surface.

い。The inorganic paper as the base material of the inorganic wallpaper of the present invention is made by a paper-making process using an inorganic compound and pulp as main components. As the inorganic paper for the inorganic wallpaper of the present invention, one having a basis weight (area density) of about 50 to 300 g / m 2 is usually used. The composition used for forming the release agent layer of the inorganic wallpaper of the present invention contains an inorganic compound and an organic binder as main components. Here, as the inorganic compound, kaolin (aluminum silicate), talc (magnesium silicate), barium sulfate, titanium oxide, zinc oxide, calcium carbonate, aluminum hydroxide, magnesium hydroxide or the like can be used. In particular, inorganic compounds containing water of crystallization, such as aluminum hydroxide and magnesium hydroxide, are desirable in terms of fireproof performance. On the other hand, as the organic binder used in the release agent layer of the inorganic wallpaper of the present invention, an organic binder having a large adhesive force, that is, an organic binder having no inorganic compound is used as an adhesive, for example, starch, dextrin,
Organic binders such as polyvinyl alcohol (PVA), acrylic resin, vinyl chloride, vinyl acetate, ethylene-vinyl acetate copolymer (EVA), styrene-butadiene rubber (SBR) can be used. As described above, it is desirable to use an organic binder having a large adhesive force and adjust the peeling force by adjusting the type of the organic binder or the compounding ratio of the inorganic compound and the organic binder. As another method of adjusting the peeling force, there is also a method of increasing the peeling property by adding a substance exhibiting peeling performance, such as wax, fluid paraffin, silicone, metal soap (metal salt of higher fatty acid), to the organic binder. I tried, but since the above substances are low-molecular weight substances that are migrating, they bleed to the interface during long-term use and increase the peeling property, and the inorganic wallpaper easily falls off spontaneously, so it is very difficult to control the peeling property appropriately. It was very difficult. The reason for this is that in the case of the inorganic compound powder, the adhesive area of the organic binder is reduced by the area of the powder occupying the peeling surface to reduce the adhesive force in the direction perpendicular to the peeling surface, but the powder particles present on the peeling boundary surface. It is presumed that because it forms unevenness on the peeling surface, it constitutes the resistance against the falling of the wallpaper. Furthermore, the inorganic wallpaper has excellent dimensional stability against changes in the environment, and it is considered that the synergistic effect brings good results against the falling of the wallpaper. The ratio of the inorganic compound and the organic binder that form the composition for the release agent layer is 3 to 100 parts by weight, preferably 5 to 60 parts by weight, based on 100 parts by weight of the inorganic compound. . If the amount of the organic binder is less than 3 parts by weight, the wallpaper is liable to fall off due to spontaneous peeling, and if it exceeds 100 parts by weight, the peeling force is too large, and it becomes difficult to practically perform smooth re-peeling. As a method of coating the release agent layer composition to the inorganic paper, an air doctor coater, a blade type, a roll type or a rod coater,
A known coating or coating method may be applied. The coating amount or adhered amount is preferably 3 to 50 g / m 2 on a dry basis, the adhesion amount is less interest and peeling proper outs to the present invention, also involves a trouble in 50 g / m 2 or more coating steps.
Hereinafter, the present invention will be described more specifically based on Examples, but the present invention is not limited to these Examples.

The composition was applied to produce an inorganic wallpaper laminate. The release agent layer was applied by coating the above composition with an air doctor knife so that the amount of adhesion when dried was 10 g / m 2 . The release agent layer side of the laminate was adhered to a noncombustible gypsum board with starch paste. Then, a slit with a width of 30 mm is made on the sheet, the tip of the inorganic paper is folded back 180 degrees, and 300 mm is obtained using a Tensilon tensile strength tester.
The tip of the folded back was pulled at a speed of / min and the peel strength was measured to obtain 190 g / 30 mm. In this test,
The surface from which the inorganic paper was peeled off had a uniform surface of the release agent layer, and a smooth surface was obtained.

上に凹凸のない再生処理面を残した。Example 2 A composition for a release layer comprising 100 parts by weight of aluminum hydroxide, 18 parts by weight of starch and 6 parts by weight of SBR was prepared.
The above composition was applied to one surface of the inorganic paper used in Example 1 to form a release agent layer, and the other surface was applied with a vinyl chloride resin layer corresponding to a decorative layer. Next, 20 g / m 2 (dry basis) of a starch paste adhesive was applied to the release agent layer surface, and then the surface was adhered to a noncombustible gypsum board. A peeling test similar to that in Example 1 was performed, and a smooth surface was obtained. The peel strength was 180 to 240 g / 30 mm. Inorganic paper without a release agent layer can be released only unevenly inside the inorganic layer or at the interface between the vinyl chloride resin and the inorganic paper, whereas in the inorganic wallpaper provided with the release agent layer of the present invention, the release agent layer interface (FIG. 1A-A), it was peeled off uniformly, and a reclaimed surface having no unevenness was left on the plaster board.
