Abstract

PURPOSE:To improve the appearance and reduce the cost by laminating a transparent resin layer having a small piece dispersion such as nonlinear monofilament mixed therein on a colored layer consisting of a foamed layer. CONSTITUTION:A base paper for a base layer 10, a colored layer 12 consisting of vinyl chloride, and a transparent layer 14 having a small piece dispersion 16 mixed therein are laminated, and a number of irregularities are provided on the surface to make it into a rough sand wall form. As the small piece dispersion 16, for example, a small piece of mica or a monofilament having a nonlinear form such as corrugated form. The colored layer 12 is formed of a foamed layer, at need. Thus, the appearance having a profoundness and the real state close to sand wall can be formed, the cost can be reduced since no printing process is required, and the fading of color can be perfectly prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper made of synthetic resin.

[0002]

2. Description of the Related Art FIG. 2 shows an example of a conventional synthetic resin wallpaper. The conventional wallpaper shown comprises a backside base layer 20 and a front side vinyl chloride layer 22. The base layer 20 is a portion to be attached to the wall surface, and the vinyl chloride layer 22 is a portion to which various patterns and colorings are applied and which a viewer can see. In the figure, the surface of the vinyl chloride layer 22 is rough, and the marble print of the grain pattern is applied here.

[0003]

In the above-mentioned conventional wallpaper, since the surface layer serving as the printing surface has a large number of irregularities, the finished state is not good even if a grain pattern or stone tone is designed and printed. Has its limits. In addition, the print surface that has been applied once fades over time due to surface abrasion, and the design is impaired.
An object of the present invention is to provide a synthetic resin wallpaper that looks good and has excellent abrasion resistance.

[0004]

According to the invention, the above-mentioned object is achieved by the means described in the claims.

That is, the invention of claim 1 is a synthetic resin wallpaper having a transparent resin layer laminated on a colored layer, in which a small particle dispersion is mixed. The invention of claim 2 is a synthetic resin wallpaper in which non-linear single fibers are mixed as the small piece dispersion, and the invention of claim 3 is a synthetic resin wallpaper in which the colored resin layer is a foam layer. It is a wallpaper.

[0006]

In the present invention, since the transparent film is laminated on the surface layer, the depth is increased and the expression close to that of a natural sand wall is possible. Moreover, since the transparent vinyl chloride layer is laminated on the surface, the composition can prevent stains and strengthen the surface.
It can improve the expression of brittleness of natural sand walls and the weakness of surface abrasion strength that conventional vinyl chloride wallpaper has.

[0007]

FIG. 1 shows an embodiment of the present invention. The illustrated wallpaper is formed by laminating a base paper of the base layer 10, a colored vinyl chloride layer 12 and a transparent vinyl chloride layer 14. The surface of the transparent vinyl chloride layer 14 is rough and has many irregularities. Further, since the small piece dispersion 16 is mixed, it is possible to express a realism close to a sand wall. No printing was done on any of the layers.

In the manufacturing process, for example, a mixture containing a coloring resin powder which is uniformly dispersed in a vinyl chloride film and which does not mix with the vinyl chloride film is rolled by a calender roll to give 0.1 mm to 0 mm. A transparent vinyl chloride film having a uniform dispersion of 3 mm of colored powder is prepared.
This transparent vinyl chloride film is laminated on the colored vinyl chloride film layer laminated on the flame-retardant paper, and is also imprinted.

The following is an example of the composition of the colored vinyl chloride layer (base layer). PVC 100 D O P 40 Chlorinated paraffin 20 Antimony oxide (Sb2O3) 5 Calcium carbonate (CaCO3) 50 Ba-Zn stabilizer 1

The following is an example of blending the transparent vinyl chloride layer (upper layer). PVC100DOP30Chlorinated paraffin20Ba-Zn stabilizer 1

An example of small pieces dispersed in a transparent vinyl chloride layer is shown below. Plum-shaped colored piece of about 1 mm square Length 1.5 to 2.0 mm, diameter 0.02 to 0.04 m
Colored monofilament at m-position Here, the monofilament is preferably a non-linear shape such as'<'or'-'. These have no direction, so
Unlike the case of the'− 'type linear filaments, the dispersed monofilaments are not fixed uniformly in the same direction.

The mixing ratio of the pieces dispersed in the transparent vinyl chloride layer should be suitable for each design to be expressed. If it is a sand wall, for cream color monofilament '10',
An example in which green and brown or the like are each '1', and further, each color of unmochi-like colored pieces is slightly mixed can be given.

The thickness of the underlying colored vinyl chloride layer is about 0.1 to 0.2 mm to about 0.3 mm, and the thickness of the upper transparent vinyl chloride layer is about 0.1 to 0.3 mm. Would be appropriate as Calcium carbonate, which exhibits flame retardancy, reduces its strength and therefore should not be included in the transparent vinyl chloride layer.

By the way, in the above embodiment, the transparent vinyl chloride layer is non-foamed and can be manufactured as follows. The base layer (containing calcium carbonate) is colored in an appropriate color on the base layer paper, and the base layer is attached by a calendar. The thickness is about 0.12 mm. The above-mentioned dispersion is mixed with the upper transparent layer, and the mixture is pasted with a calendar. The thickness is about 0.2 mm. Then, heat imprinting is performed by the embossing machine.

On the other hand, when the transparent vinyl chloride layer is used as the foamed layer, it may be carried out as follows. ADCA as the underlayer
(Azodicarboxylic acid amide) is added in 3 PHR, further colored and pasted with a calendar. Thickness is 0.10
It is about mm. Similar to the case of the non-foamed layer, the upper transparent vinyl chloride layer is attached thereto. Then, it is heated and foamed by a printing machine to be printed.

In this embodiment, vinyl chloride is used as the resin constituting the wallpaper, but EVA resin, SEBS
It goes without saying that other resins such as resin and polyethylene resin may be used, and the colored layer may be filled with a transparent member such as stained glass.

[0017]

As described above, according to the present invention,
Since the colored resin powder is granular and uniformly dispersed, it has a deeper appearance than conventional vinyl chloride resin wallpaper. Also,
By using the small piece dispersion, it is possible to express the realism closer to the sand wall than the gravure printed product. Further, since multicolor expression can be performed without going through the printing process, cost reduction can be achieved by shortening the process. Moreover, there are various effects that there is no worry of discoloration.
