[Problems to be solved by the device]

 However, the above-mentioned paper wallpaper is peeled off with a peeling agent etc. in the case of construction of a wall on which the wallpaper has already been pasted, but it does not peel off cleanly and the paper layer partially remains on the wall surface and the wall surface is smooth. I didn't. In addition, the stripped wallpaper can be incinerated easily because it can be incinerated. However, in terms of design, the rugged pattern was not enough to create a sense of volume. On the other hand, vinyl wallpaper also has two layers, a surface layer (23) (vinyl chloride layer) and a base layer (20) (flame-retardant backing paper). Although it will be pasted on the remaining underlayer, the surface layer and the underlayer will not be peeled off cleanly, and the unevenness of the underlayer will remain on the wall surface. In other words, in both cases, the peelability (the surface peels off smoothly and smoothly like delamination) is low, and it takes time to flatten the wall during construction. Furthermore, regarding the treatment of the vinyl chloride layer on the peeled surface layer, the problem of harmful gas remained when incinerated.

In view of this, the present invention uses a two-layer paper made of recycled paper as a base material and provides a non-woven fabric made of a natural material on the paper, and uses a water-based ink and a non-vinyl chloride resin ink on the non-woven fabric. It is intended to provide a wall-mounted decorative material having a pattern layer and improved in design.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a nonwoven fabric (14) made of a natural material on a substrate (10) made of recycled paper via an adhesive (13), and an aqueous ink on the nonwoven fabric. A first pattern layer (11) according to the above, a second pattern layer (12) based on an acrylic emulsion ink containing a foaming agent, and a top coat layer (15) provided on the pattern layer. It is a decorative material for wall decoration (18). In addition, the base material (10) made of the recycled paper is composed of a two-layer paper recycled paper, an upper layer paper (10b) and a lower layer paper (10a) with different amounts of recycled pulp mixed. .

[0006]

[Action]

 Since the non-vinyl chloride resin is used in all of the wall covering decorative materials of the present invention, it becomes possible to easily dispose of it, and it is possible to suppress the generation of toxic gas even when incinerated. In addition, by using a two-layer paper made of recycled paper as the base material, it can be peeled off neatly like a correlated peeling phenomenon when using a peeling agent from the joint between the upper and lower layers of recycled paper without using a peeling agent. , The workability is improved because no unevenness remains on the surface of the lower layer paper.

【Example】

 An embodiment will be described with reference to the drawings. FIG. 1 is a side view showing an example of a wall-mounted decorative material according to an embodiment of the present invention.

As shown in FIG. 1, a substrate (10) is made of recycled two-layer paper, and the ratio of the upper layer paper (10b) and the lower layer paper (10a) is 1: 1. Has excellent peelability, and if the ratio of the upper layer paper (10b) decreases, the peelability decreases.

Further, recycled paper obtained by adding a small amount of virgin pulp to recycled pulp obtained by treating waste paper with a bleaching agent, hydrochloric acid, etc. and having a high recycled pulp ratio is fragile, and therefore, the base material (10) used is recycled. The upper layer paper (10b) made of paper was made from 50% virgin pulp and 50% recycled pulp, and had a higher mixing ratio of virgin pulp than the lower layer paper (10a). On the other hand, the lower layer paper (10a) is made of recycled paper made with 30% virgin pulp and 70% recycled pulp. However, the recycled paper ratio (mixed amount of recycled pulp) of the upper layer paper and the lower layer paper was 65% or more.

In this two-layer paper made from recycled paper, the proportion of long fibers and short fibers is the same in order to make the expansion / contraction in water (stretching in the lateral direction and shrinking more than expanded when dry) 0.8% or less. The paper is made in this way, which prevents the openings (opening between the wallpapers due to expansion and contraction of the paper after construction).

In the present invention, the interlayer strength is improved by changing the normally used phosphoric acid compound to a polymer type as the flame retardant for imparting flame retardancy.

In addition, when the wallpaper is pasted, the construction can be facilitated by increasing the open time (the time from the application of the adhesive to the time of adhering). Therefore, this recycled paper can be increased in size to make paper. did. It is also possible to extend the open time by printing with a water-based varnish.

A non-woven fabric (14) made of a natural material is adhered to a base material (10) made of recycled paper made of two layers, and the adhesive (13) used at this time is a urethane type. It is an adhesive made of resin, which maintains open time and gives the overall softness. I tried using other adhesives, but after drying, the whole became hard and was not suitable as a wall decoration material. Further, as the non-woven fabric (14) made of a natural material, there are cotton, hemp, etc., but in the present embodiment, a non-woven fabric made of 100% cotton was used.

When a non-woven fabric is attached to this base material, a volume feeling appears, and when the first pattern layer (11) made of an aqueous ink and the second pattern layer (1 2) of acrylic emulsion ink containing a foaming agent are printed. However, a part of the ink penetrates into this non-woven fabric, resulting in a design with increased depth. As the acrylic emulsion ink for the second pattern layer, an aqueous emulsion having an organic component of 30 g / m ² or less was used.

Further, a top coat layer (15) is applied and dried on the non-woven fabric (14) provided with a pattern layer in order to protect the pattern layer, to give a three-dimensional effect and a more voluminous feeling.

The above wall decoration material (20) is made by removing the synthetic resin as much as possible from various kinds of materials so that it can be easily incinerated. The acrylic emulsion ink resin, the top coat resin, and the synthetic resin of the adhesive were used in a total amount of 30 g / m ² or less.

<Example 1> A specific example will be described in detail. A two-layer paper made from recycled paper (SF-160T, manufactured by Sun Fiber Co., Ltd.) is used as a base material, and an adhesive (Hw312B, manufactured by Dainippon Ink and Chemicals Co., Ltd.) is applied onto this as a base material. A non-woven fabric made of 100% cotton (manufactured by Nisshinbo Industries Inc., OISCO) is applied. Acrylic emulsion ink (Clean Coat # 45T, manufactured by Atom Chemical Co., Ltd.) with a first pattern layer made of water-based ink (ATS, manufactured by Toyo Ink Mfg. Co., Ltd.) was added to this nonwoven fabric, and a foaming agent was further added. After forming a second pattern layer by gravure printing and foaming this acrylic emulsion ink in a foaming oven to form a concavo-convex pattern, a top coat resin (u-302 manufactured by Dainichiseika Kogyo Co., Ltd.) is used as a protective layer. It is applied and dried to make a wall covering decorative material.

[Effect of device]

 The wall-mounted decorative material of the present invention uses a two-layer paper made of recycled paper as a base material, and a non-woven fabric made of a natural material is provided on the base material via an adhesive. By providing the second pattern layer and the top coat layer, it has superior peelability, open time, and workability compared to conventional wallpaper, and by stacking non-woven fabrics, the design is further improved in terms of volume and three-dimensionality. It is an improved wall covering material. In addition, since it is a product that has been attracting attention in recent years and is environmentally friendly, and because it uses non-vinyl chloride resin in all, it does not generate toxic gas even when incinerated.
