DETAILED DESCRIPTION OF THE INVENTION Tourmaline has the general formula (Na, C)
a) (Al, Fe, Li, Mg, Mn) ₃ B ₃ Al
₃ (AlSi ₂ O ₉ ) ₃ (O, OH, F) ₄ is a silicate mineral that has spontaneous polarization and exhibits remarkable piezoelectricity and pyroelectricity. .

[0013] Since tourmaline powder particles are charged with static electricity due to spontaneous polarization, when they come into contact with water molecules, they instantaneously discharge to generate hydrogen gas and hydroxyl ions, which have the effect of weakly alkalizing water. It has been known. In the air, the water in the air is similarly electrolyzed and hydroxyl ions generated are released into the air, so that the air is negatively ionized. It is known that negatively ionized air has various favorable effects on the human body, such as promotion of metabolism, promotion of blood circulation, recovery of fatigue, enhancement of appetite, sleep, and analgesia.

In addition, the deodorizing effect, antibacterial effect, and air purifying effect caused by the action of the static electricity adsorbing and repelling the substance, and the far infrared rays by emitting the energy accumulated by the piezoelectricity or pyroelectricity as electromagnetic waves. It is known to have various effects that are favorable to human living environment, such as emission effects. Also, since tourmaline constantly maintains its spontaneous polarization, the various effects described above are:
It is also known that it is retained forever without being lost or degraded over time by a chemical reaction.

The present invention has the above-mentioned functions such as negative ion effect, deodorant effect, antibacterial effect, air purifying effect, far-infrared ray emitting effect, etc. by incorporating the above-mentioned tourmaline powder into wallpaper and wall members. The purpose is to contribute to the health of residents and users of the building.

The structure of the wallpaper of the present invention is, for example, as shown in FIG. 1, in which a resin layer 2 and a picture printing layer 3 are sequentially laminated on a paper base 1, and the paper base 1 and the resin It is characterized in that at least one of the layer 2 and the pattern printing layer 3 contains tourmaline powder.

As the paper substrate 1, a paper which can be separated between papers is usually used. When the tourmaline powder is contained in the paper base material 1, the tourmaline powder may be uniformly contained in the entire paper base material 1, or only the base paper remaining on the wall surface after peeling or the base paper is peeled and removed together with the pattern. May be contained only in the base paper. Above all, the tourmaline powder contained in the base paper remains on the wall surface even after peeling, and the effect can be exhibited even after the wallpaper is replaced. There is an advantage that the effect can be obtained for a long period of time while using the least amount of tourmaline powder.

Examples of the method for incorporating the tourmaline powder into the paper substrate 1 include an internal addition method in which pulp is added during papermaking, a coating method in which a coating agent containing tourmaline powder is applied to the surface of the paper, Any method such as an impregnation method of impregnating paper with a resin solution in which tourmaline powder is dispersed can be used.

Conventionally, the resin layer 2 is mostly made of polyvinyl chloride resin. However, in recent years, an organic solvent used for applying the polyvinyl chloride resin paste or hydrogen chloride gas generated during incineration has been used. Of acrylic resin, polyolefin resin, vinyl acetate resin, urethane resin, etc., which do not contain chlorine, formed by applying an aqueous emulsion containing no organic solvent, in view of the problem of environmental pollution due to I'm doing

The resin layer 2 is provided with an inorganic foaming agent such as sodium hydrogencarbonate or ammonium carbonate, azodicarbonamide, An organic foaming agent such as bisisobutyronitrile, or a microcapsule foaming agent containing a gas or a low-boiling liquid inside a microshell made of a thermoplastic resin, etc., may be added and heated and foamed after coating. it can.

Further, a mechanical embossing method for forming an uneven pattern on the surface using a metal embossing plate after heat foaming, and a method of forming a pattern with an ink containing a foaming accelerator or a foaming inhibitor on the resin layer 2 before foaming. Can be formed on the surface of the resin layer 2 by a chemical embossing method or the like in which an uneven pattern synchronized with the pattern is formed by printing and heating and foaming.

When a transparent or translucent resin is used as the resin layer 2, as shown in FIG.
It is also possible to adopt a configuration in which the resin layer 2 is provided thereon, and it is possible to obtain wallpaper having a sense of depth of the design. Of course, also in this case, the resin layer 2 can be foamed or embossed on the surface as long as the transparency of the resin layer 2 is not lost.

As the pattern printing layer 3, a normal printing ink can be used. In addition, when a foaming ink is used, or when the resin layer 2 is foamable, the above-mentioned foaming accelerator or foam suppressing agent is used. There is also a method of forming irregularities synchronized with a picture using an ink containing an agent or the like, and these may be used in any combination.

When the paper substrate 1 does not contain tourmaline powder, either the resin layer 2 or the pattern printing layer 3 contains tourmaline powder. It is difficult to design the amount of tourmaline to be used because the amount of coating is generally small and depends on the pattern used. Particularly in the case of light-colored patterns, the amount of ink used is very small, and even if the tourmaline powder is added as much as possible without impairing printability, sufficient effects may not be obtained as a result. It is more advantageous to include it in layer 2 or paper substrate 1.

In addition, as shown in FIG. 3, when a transparent or translucent resin layer (hereinafter referred to as a surface resin layer 4) is further provided on the picture print layer 3 provided on the resin layer 2, the wallpaper Can be improved in stain resistance and abrasion resistance. As the surface resin layer 4, for example, a polyolefin resin, an acrylic resin, a polyester resin, a fluororesin, or the like is used, and a coating method, a melt extrusion lamination method, a film lamination method (a thermocompression bonding method, an adhesive method), or the like is used. It is laminated.
If necessary, the surface of the surface resin layer 4 may be further embossed with irregularities or a top coat.

Although the surface resin layer 4, adhesive layer, top coat layer and the like may contain tourmaline powder, transparent and colorless tourmaline is expensive.
In order to be able to use inexpensive black or red opaque tourmaline powder, it is preferable to avoid adding it to a constituent layer closer to the surface than the pattern printing layer 3 such as the surface resin layer 4.

As described above, the wall member of the present invention can be used as a wall paper containing tourmaline powder in any one of the constituent layers as described above, for example, wood-based materials such as plywood, laminated wood, particle board, and inorganic materials such as gypsum board. It can be obtained by sticking to the surface of a substrate for a wall member made of various materials such as a system material, a metal, and a synthetic resin.
