Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wallpaper made by applying makeup to the surface of a backing paper.

[0002]

2. Description of the Related Art Wallpapers are broadly classified into vinyl wallpaper, cloth wallpaper, juryu wallpaper and paper wallpaper depending on the material of the decorative layer applied to the surface of the backing paper. The vinyl wallpaper is formed by covering the surface of the backing paper with a vinyl resin, and the material feeling of the backing paper is hidden by the vinyl resin. The cloth wallpaper is formed by laminating threads and cloth on the surface of the backing paper, and the material feeling of the backing paper is hidden by the threads and cloth. The Juraku wallpaper is made by spreading and adhering scale-like or granular aggregate on the surface of the backing paper, and the texture of the backing paper is hidden by the aggregate-dispersing layer. Paper wallpaper is formed by embossing or printing on the surface of the backing paper, in which case a solid ink is printed on the surface of the backing paper, which solid ink evenly colors the surface of the backing paper. The coating film is extremely thin, and the texture of the backing paper appears on the surface of the ink coating film.

The surface of a vinyl wallpaper in which a vinyl resin is laminated on the surface of a backing paper and the surface of a paper wallpaper on which a solid ink is printed are smooth and easy to print, and most of them have a print pattern. On the other hand, the surface of cloth wallpaper and juryu wallpaper is composed of irregularities due to fibers and aggregates, and when a print pattern is applied to the surface, ink bleeds out and the outline of the pattern becomes unclear, and much of the ink is It is not possible to draw a print pattern with a three-dimensional effect because it is absorbed by cloth or aggregates, so it is extremely rare to apply a print pattern. I can't find anything with a pattern.

[0004]

[Problems to be Solved by the Invention] As a method of drawing a three-dimensional print pattern on the surface of a cloth wallpaper or a Juraku wallpaper,
A method is considered in which an ink containing a foaming agent is printed, and the ink is foamed to raise a print pattern on the irregularities formed by fibers and aggregates. However, since the foamed ink coating film is composed of an assembly of ultra-thin cell walls, it lacks abrasion resistance, the binder resin itself of the ink is flammable, and the foamed structure with voids is A flameproof wallpaper cannot be obtained as it makes the coating flammable.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention provides a three-dimensional printed pattern on the surface of a cloth wallpaper or a falling wallpaper, which has fine irregularities on the surface, ink easily bleeds out, and a printed pattern is difficult to apply, and wear resistance is improved. The purpose is to obtain a wallpaper that is highly flameproof.

[0006]

[Means for Solving the Problems] Wallpaper 16 according to the present invention
Is the base material 11, the fiber powder 12 and the binder resin 1
The base material 11 is printed with the ink 15 containing the inorganic filler 14 of 3 and 100 PHR or more. The length of the fiber powder 12 is 1 mm or less, and the content of the fiber powder 12 contained in the ink 15 is 50 mm.
It should be set to PHR or less. The base material 11 has a backing paper (17) that constitutes the back surface of a normal wallpaper, or a fall wall formed by spreading and adhering an aggregate 19 on an adhesive 18 applied to the surface of the backing paper 17. It is effective to apply a cloth wall cloth having fibers laminated on the surface of the cloth 11 or the backing paper (17).

[0007]

In the present invention, the ink 15 to be printed contains a large amount of the inorganic filler 14 which is hard to penetrate into the base material 11 as compared with the binder resin 13 which easily penetrates into the base material 11. Even when printing on an uneven backing paper 17 or an uneven surface such as a cloth or an adhesive dispersion surface (19) of a falling wallpaper, a thick ink coating film 15 is formed to prevent ink from entering the fine gaps, and the base material 11 is formed.
The texture of paper, fibers, aggregates, etc. is hidden by the ink coating film 15 and does not appear on the surface, and as a result, a print pattern having a three-dimensional effect is rendered. On the other hand, when the blending ratio of the binder resin 13 is reduced and the blending ratio of the inorganic filler 14 having no film-forming property is increased, the ink coating film 15 is likely to be cracked and lacks abrasion resistance. Then, since the fiber powder 12 that connects the inorganic fillers 14 in the ink coating film (15) is blended, the ink coating film 1
5 does not easily crack, and a print pattern having abrasion resistance is drawn. However, if the blending ratio of the binder resin 13 is too low, the fiber powder 12
The adhesiveness between the inorganic filler 14 and the inorganic filler 14 and the adhesiveness between the base material 11 and the ink coating film 15 are insufficient, and the intended effect of the present invention cannot be obtained.

In consideration of this point, the compounding ratio of the inorganic filler 14 is 100 to 1000 PHR, preferably 400 to 6 PHR.
The length of the fiber powder 12 is set to 1 mm or less in consideration of the clogging of the screen of the printing machine, and the length of the fiber powder 12 is set from the viewpoint of the effect as a connecting material between the inorganic fillers (14). The particle size of the inorganic filler 14 is twice or more the particle size of the fiber filler 12, and the compounding amount of the fiber powder 12 is 50 PHR or less. In the present invention, "PHR" is an abbreviation for "Per Hand Red Resin", which means a blending weight part of an inorganic filler or a fiber powder with respect to 100 parts by weight of a binder resin (solid content). Agent 300PHR
Means that 300 parts by weight of an inorganic filler is mixed with 100 parts by weight of a binder resin (solid content).

As the inorganic filler 14, calcium carbonate, titanium oxide, talc, diatomaceous earth, zeolite or the like can be used, but aluminum hydroxide is used to impart high flameproofness to the ink coating film 15. Is recommended. In particular, in order to obtain the flameproof wallpaper 16, the aggregate 19 as well as the ink 15 is mixed with the fiber powder 12 and the binder resins 13 and 10.
A granular wallpaper or scale-like composition with an inorganic filler 14 of 0 PHR or more, which is sprayed and adhered on an adhesive 18 which is sprayed on the surface of a flame-retardant backing paper 17, or a flame-retardant commercially available. It is advisable to use a cloth wallpaper in which a glass fiber cloth is laminated on the surface of the backing paper for the base material 11. Printing may be performed using a rotor screen printing device.

[0010]

As described above, according to the present invention, the ink 15
Is hard to penetrate into the base material 11 and forms a thick ink coating film 15. The ink coating film 15 hides the material feeling of the base material to obtain a three-dimensional wallpaper 16.

Since the ink coating film 15 is reinforced by the fiber powder 12, it is hard to crack and a wallpaper 16 having abrasion resistance can be obtained.

In the present invention, the amount of the binder resin 13 which is a combustible substance in the ink 15 is smaller than the amount of the non-combustible inorganic filler 14 and the fiber powder 12 contains pulp or other combustible fibers. Even if it is used, the amount thereof is smaller than that of the binder resin 13, so that the wallpaper 16 is not made combustible by the ink coating film 15 and the base 1
In the same manner as the ink 15, the aggregate 19 is the fiber powder 12, the binder resin 13, and the inorganic filler 1 of 100 PHR or more.
By using a non-combustible wallpaper which is formed into a granular shape or a scale shape by 4 and is spread and adhered on the adhesive 18 which is spread on the surface of the flame-retardant backing paper 17, a novel design is also possible. The non-combustible wallpaper 16 can be obtained.
