More specifically, the present invention relates to a wrinkle, wavy or undulating material even though a coating solution of a non-organic solvent resin is used. The present invention relates to a wallpaper material, a wallpaper, and a method for producing the same, which prevent curling and enable high-speed coating, thereby achieving high productivity and excellent workability.

れるいわゆる化学物質過敏症が注目されている。2. Description of the Related Art Conventionally, so-called vinyl chloride wallpaper, in which a vinyl chloride resin layer is formed on a paper base material, has been widely used as an interior material of a building, but an organic solvent is used in the wallpaper manufacturing process. Therefore, there is a problem in the work environment hygiene.
Furthermore, in recent years, so-called chemical hypersensitivity, which is said to cause a solvent contained in various interior materials to volatilize into a room and affect a human body though the amount thereof is extremely small, has attracted attention.
【０００３】そこで、非有機溶剤系樹脂層を設けた壁
紙、例えば紙基材の上に水系樹脂ディスパージョン塗布
液を塗工し樹脂層を形成した壁紙が知られている。Therefore, a wallpaper provided with a non-organic solvent-based resin layer, for example, a wallpaper formed by applying a water-based resin dispersion coating solution on a paper substrate to form a resin layer is known.

じる。However, paper as a base material has a water absorbing property, and has a drawback that the paper itself is stretched by absorbing water. In addition, it is inevitable that the pulp fibers are unevenly dispersed and uneven during the production of the paper, which means that when a coating liquid of a non-organic solvent-based resin such as an aqueous resin dispersion is applied and dried. It may cause wavy or curl. That is, a place where the pulp fiber is large and a place where the pulp fiber is small naturally have different amounts of water absorption, and curling occurs due to a difference in drying speed.

されており、非常に生産性が低いのが実情である。[0005] The paper base material having the wavy or curled shape as described above cannot be subjected to printing or embossing for decoration and has a reduced value as a product. It is necessary to apply the coating solution of the non-organic solvent-based resin at a slow speed so that the water absorption state is saturated, and to slowly dry the paper base material at a temperature lower than the boiling point of water. The fact is that productivity is low.

塗工がなされるという効果が奏される。Next, the production of the wallpaper of the present invention will be described. FIG. 2 shows a sectional view of one embodiment of the wallpaper of the present invention. First, the waterproof material layer 3 is provided on one surface of the sheet material 2 in a dot shape or a dot net shape by, for example, gravure printing as described above, and the wallpaper material 1 is produced. At this time, it is preferable that the sheet material 2 before the waterproof material layer 3 is provided is subjected to a static electricity removing process and / or a fine powder removing process in advance. The static electricity removing process is achieved by, for example, applying a high voltage to the sheet material 2 or blowing ionized air, and the fine powder removing process is achieved by, for example, suction. By performing these pretreatments, there is an effect that the waterproof material layer 3 and the non-organic solvent-based resin layer 4 can be uniformly coated.

As described above, a foaming agent can be appropriately added to this coating solution. According to the present invention, this coating operation can be performed at a coating speed of 80 to 200 m / min. This speed is 4 to 10 times faster than the wallpaper using the conventional aqueous resin dispersion.

° C is good. FIG. 3 shows a cross-sectional view of the wallpaper of the present invention after a series of steps of pattern printing, foaming, and embossing. These steps are preferable because the design is further enhanced. In printing the pattern, a printing ink containing a foaming agent can be used.

The wallpaper as shown in was prepared. As the sheet material 2,
A base paper for wallpaper having a basis weight of 70 g / m 2 was used, and an ink in which an acrylic resin was dissolved in toluene was applied to the base paper in a dotted network by gravure printing to form a waterproof material layer 3 on the base paper, thereby producing a wallpaper material. The air permeability at this stage is determined by JISP8117
According to the data, it was 60. Next, an aqueous resin dispersion coating solution having the following composition was applied on the waterproof material layer 3 by roll coating at a coating amount of 140 g / m 2 to form a non-organic solvent-based resin layer 4. The coating speed was 120 m / min, which was extremely good.
