Description

  The present invention relates to finishing materials such as ceiling materials and wall materials, and in particular, at least one of diatomaceous earth, vermiculite, gypsum slag, ALC (lightweight cellular concrete) powder, calcium silicate, and slaked lime, or these The present invention relates to a finishing material provided with a substrate mainly composed of the above mixture and a Japanese paper layer integrated with the substrate.

  Finishing materials used for ceilings and walls determine the atmosphere of the room in which they are used, so it is necessary to have excellent design characteristics, and naturally envelop human living spaces. Therefore, moisture retention, constant moisture absorption and moisture release (hereinafter sometimes collectively referred to as moisture absorption / release) are also required. In recent years, the function of adsorbing harmful substances generated from various building materials (adsorbability) has also been required for this type of finishing material, and this adsorptivity can cause a so-called “sick house syndrome” disease. It is desired to be able to suppress it.

  Furthermore, for this type of finishing material, “antifouling” as in wallpaper is also required, and “breathability” for improving the above-mentioned “adsorption” has also been required. The demand for the function to perform is also made.

  In order to satisfy the various requirements for the finishing material as described above, for example, Patent Document 1 and Patent Document 2 propose countermeasures.

  Patent Document 1 states that “by providing a resin film having micropores in the surface layer, it has a function that makes it extremely difficult to achieve both antifouling properties and air permeability, and further, An invention relating to “interior material” for the purpose of providing “interior material also having an odor function” is described.

  The “interior material” described in Patent Document 1 is “a resin having a thickness of 8 μm to 30 μm, in which the surface layer has air-permeable fine holes in the interior material formed of at least one lower layer and a surface layer. It is characterized by being made of a film, and by this, it has a function that makes it extremely difficult to achieve both antifouling properties and air permeability, and also has a deodorizing function due to the air permeability. It is thought that it can be “having” interior material.

  However, if “resin film with air permeability of fine pores of 8 μm to 30 μm” is used as “surface layer”, can it be easily broken when people or objects come into contact with this resin film? No, the question remains.

  On the other hand, Patent Document 2 proposes a technique related to “humidity control building material” for the purpose of “providing a humidity control building material that exhibits an excellent humidity control function”. As shown in FIG. 3, “the porosity of the humidity control building material 1 is 58%, and in the base material 2, a large number of micropores 3, pulp 4, diatomaceous earth 6, and the like are scattered. On one surface, a water-repellent layer 9 is formed by applying a water-repellent paint, and micropores 5 having an inner diameter of 0.1 μm to 10 μm are present in an open state from the surface of the water-repellent layer 9 to the outside. In addition, a moisture-permeable layer 7 is interposed between the water-repellent layer 8 and the substrate 2, and the moisture-permeable layer 7 contains a fibrous titanate potassium whisker 8 ”. It is what you are doing.

  According to the humidity control building material of Patent Document 2, “when the surroundings of the humidity control building material 1 are in a high humidity condition, the water vapor in the air passes through the micropores 5 opened on the surface of the water repellent layer 9. 3, when it is in a dry state, the water vapor taken into the micropores 3 of the base material 2 is dissipated into the air through the route opposite to that described above. It is considered that “exhibits an excellent humidity control function”.

  However, in the humidity control building material of Patent Document 2, the function of “humidity control” is sufficient, but by itself, “beauty” or “design” is not satisfied, and “interior material that determines the atmosphere of the room” May be insufficient.

JP 2007-276160 A, Summary Japanese Patent Laid-Open No. 2005-163474, abstract, representative diagram

  The technology described in Patent Documents 1 and 2 described above was intended to improve a specific function, but as described above, the interior material or the finishing material as a ceiling material or a wall material, Since it forms a living space for people, various functions are required. Especially, the design properties are greatly required for these interior materials and finishing materials.

  There are various “design properties” that create a feeling that people feel beautiful or feel relieved when they are inside, so it is necessary to create designs that seem to be good for everyone. Nearly impossible. However, for so-called natural materials, people think that they are beautiful in common, and they have used beautiful wooden boards for ceiling materials and arranged bamboo on wall materials.

  It is not so easy to produce an interior material using these trees and bamboo as they are, and it is not easy to have sufficient moisture retention and moisture absorption / release properties.

  Therefore, the present inventors are close to those using natural materials in design, and as a result of various investigations on how to make interior materials having sufficient air intake and moisture absorption / release properties, As a substance having the characteristics of soil that has been used since ancient times, at least one of diatomaceous earth, vermiculite, gypsum slag, ALC powder, calcium silicate, slaked lime, or a mixture thereof is inhaled. Recognizing that Japanese paper has a certain level of toughness and natural material design, the present invention has been completed. It is.

  That is, the object of the present invention is to first provide a finishing material that has sufficient adsorption of chemical substances that cause sick house syndrome, is excellent in moisture absorption and desorption, and is also excellent in design. Second, it is to further improve the moisture absorption / release property and the air intake property of the finishing material.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“A substrate 11 mainly composed of at least one of diatomaceous earth, vermiculite, gypsum slag, ALC powder, calcium silicate, slaked lime, or a mixture thereof, and 50 to 250 g on the surface side of the substrate 11 The decorative layer 12 containing a pigment or dye that is applied at a rate of / m ² and decorates the surface of the substrate 11 is pasted on the decorative layer 12 and has a basis weight of 6 to 100 g / m. Finishing material 10 comprising ^two Japanese paper layers 13 and a protective layer 14 applied to the surface of the Japanese paper layer 13 at a rate of 10 to 100 g / m ² ”
It is.

  That is, as shown in FIGS. 1 and 2, the finishing material 10 according to claim 1 is excellent in air-absorbing property and moisture absorbing / releasing property, such as diatomaceous earth, vermiculite, gypsum slag, ALC powder, calcium silicate, Or Japanese paper with which a substrate 11 mainly composed of at least one of slaked lime or a mixture thereof has a large number of through holes intricately entangled with material fibers, and further, fuzz is suppressed by a protective layer 14 The layer 13 is integrated, and the pigment or dye in the decorative layer 12 formed on the substrate 11 through the through hole of the Japanese paper layer 13 develops color as shown in FIG.

  Here, the “Japanese paper” forming the Japanese paper layer 13 will be described. The term “Japanese paper” or the material and the manufacturing method are not defined, so in this specification ), Mitsumata, ganpi, manila hemp, rayon, or a mixture thereof. In addition, although there is a method of definition on the manufacturing method such as “sinking”, here, the manufacturing method is not limited according to the above-described definition on the material.

  Now, the substrate 11 whose main material is at least one of diatomaceous earth, vermiculite, gypsum slag, ALC powder, calcium silicate, slaked lime, or a mixture thereof is naturally the back side (with the Japanese paper layer 13 and In some cases, the shape-retaining paper may be integrated on the opposite side). This shape-retaining paper is preferably a so-called “paper” rather than the Japanese paper layer 13. This is because the paper is advantageous to uniformly integrate the diatomaceous earth into a plate shape while reliably preventing the diatomaceous earth from collapsing.

  In particular, the substrate 11 must be mainly composed of at least one of diatomaceous earth, vermiculite, gypsum slag, ALC powder, calcium silicate, and slaked lime, or a mixture thereof. Since these diatomaceous earths have a very large number of micropores when viewed microscopically, the chemical substances are sufficiently adsorbed by the gaps between these micropores and each diatomaceous earth. Because it can. In addition, the manufacturing method of the board | substrate 11 itself which has as a main material at least 1 type in any one of these diatomaceous earth, vermiculite, gypsum slag, ALC powder, calcium silicate, slaked lime, or these mixtures is performed conventionally. It can be a general one.

  Since the diatomaceous earth itself that mainly constitutes the substrate 11 is white, if a predetermined color is to be imparted to the finishing material 10, there are corresponding pigments (for example, extender pigments such as inorganic pigments and organic pigments). ) Or dyes.

  Further, since diatomaceous earth is exposed on the surface side of the substrate 11 (the side opposite to the shape-retaining paper described above), it is necessary to prevent the diatomaceous earth from collapsing. Therefore, in the finishing material 10 of the present invention, the decorative layer 12 is formed on the surface side of the substrate 11.

  The decorative layer 12 is formed by applying, for example, a roller on a surface of the substrate 11 that is configured as a so-called paint in which an acrylic emulsion and a pigment are dispersed in a solvent. After volatilization, an acrylic resin and a pigment are formed in layers on diatomaceous earth or the like. Thereby, while the surface of the board | substrate 11 is colored with the decorating layer 12, it is hold | maintained so that the diatomaceous earth which comprises the board | substrate 11 may not collapse.

The decorative layer 12 made of this acrylic emulsion resin and a pigment or dye needs to be applied at a rate of 50 to 250 g / m ^2. The reason is that the decorative layer 12 is first applied. If the amount is less than 50 g / m ² , each diatomaceous earth is not sufficiently integrated, and the diatomaceous earth collapses or peels off. Naturally, the amount of pigments and dyes to be colored is reduced, which is necessary. This is because sufficient coloring cannot be performed. On the other hand, when the coating amount of the decorative layer 12 is more than 250 g / m ² , coloring with pigments and dyes is sufficient, but the air-absorbing property and moisture-absorbing / releasing properties such as bent diatomaceous earth are impaired, This is because the desired function cannot be exhibited. Above all, the coating amount of the decorative layer 12 is preferably about 50 to 80 g / m ² .

  As the acrylic emulsion resin constituting the decorative layer 12, an aqueous composition such as acrylic, urethane, silicon, fluorine, or epoxy is suitable, and an inorganic resin is used. It is also possible to add it sufficiently. Moreover, as an oil-and-fat composition, natural compositions, such as the above-mentioned composition, castor oil, rapeseed oil, starch powder, and konjac powder, are applicable.

  As shown in FIG. 2, a Japanese paper layer 13 is affixed on the decorative layer 12 as described above. The Japanese paper layer 13 has a predetermined pattern or entanglement of fibers constituting the same. The random pattern by is given. The Japanese paper layer 13 has a large number of through holes because the entanglement of each fiber is random, and the color of the lower decorative layer 12 can be seen through the through holes at random. become.

  In addition, the decorative layer 12 may be omitted as necessary (to improve humidity control and adsorptivity).

Here, the thickness of the paper layer 13, it is necessary in the basis weight is 6~100g / m ^2, because, firstly, the basis weight of the paper layer 13 is less than 6 g / m ² This is not only difficult to break and difficult to produce in the factory, but also because the pattern of the Japanese paper layer 13 itself is not clearly visible. On the other hand, when the basis weight of the Japanese paper layer 13 is greater than 100 g / m ² , the number of through holes is reduced, and not only the air intake properties and moisture absorption / release properties of each diatomaceous earth cannot be fully utilized. This is because the color development of the layer 12 is inhibited, and among these, the basis weight of the Japanese paper layer 13 is preferably 12 to 45 g / m ² .

  Moreover, as an adhesive agent which sticks this Japanese paper layer 13 to the decoration layer 12, the emulsion resin itself in the decoration layer 12 may be used, or a completely different starch paste or konjac powder is used. Also good. Needless to say, when the adhesive strength of the decorative layer 12 is used, the Japanese paper layer 13 is applied within a short time after the decorative layer 12 is formed.

  Of course, if the surface of the Japanese paper layer 13 is left as it is, the fibers constituting it may be partly fuzzy. It will be fluffy. Therefore, it is necessary to suppress the fuzz of these fibers, but it is the protective layer 14 that does this.

The protective layer 14 is a transparent paint containing a matting material called so-called clear, and may be made of a material such as polyethylene, silica, alkyd, or entirely different starch paste or konjac powder. Since this protective layer 14 is intended to suppress fuzz without filling the through-holes of the Japanese paper layer 13, the coating amount is most preferably 40 to 50 g / m ² .

  In the finishing material 10 according to the present invention configured as described above, at least one of diatomaceous earth, vermiculite, gypsum slag, ALC powder, calcium silicate, and slaked lime mainly constituting the substrate 11, or Not only the pigments or dyes in the decorative layer 12 are firmly adhered to these mixtures, but also each diatomaceous earth and the like itself is fixed by the decorative layer 12. However, the porous properties of each diatomaceous earth and the like are not inhibited by the decorative layer 12.

  Further, even when attached to the Japanese paper layer 13 on the decorative layer 12, the protective layer 14 not only protects the surface (becomes less fuzzy), but the Japanese paper layer 13 inherently has it. The through-holes are also left as they are. Of course, the pattern of this Japanese paper layer 13 is not only appearing on the surface of the finishing material 10, but the decorative layer 12 is colored as shown in FIG. It is a very beautiful design.

  When the finishing material 10 is constructed, it is positioned and temporarily fixed on the base material with an adhesive or a double-sided adhesive tape, and is fastened with a nail or a screw. 13 is present, this Japanese paper layer 13 sufficiently holds nails and screws. That is, the finishing material 10 can be nailed or screwed as it is by the tough Japanese paper layer 13 on the surface. Moreover, even if diatomaceous earth or the like is softened with a large amount of moisture, the finishing material 10 is not peeled off from the ceiling or wall because it is covered with the tough Japanese paper layer 13. It is.

  After the finishing material 10 is constructed, the micropores of the diatomaceous earth and the like can be sufficiently exposed to the outside air through the Japanese paper layer 13, so that the chemical substances vaporized in the room are scattered. Even if it is, it can be sufficiently adsorbed by diatomaceous earth. This is also true for moisture. If the moisture in the room is more than necessary, it is adsorbed by diatomaceous earth, and conversely, if the room is greatly dried, diatomaceous earth is retained. The humidity in the room is always kept at a moderate level because the moisture is released into the room.

  Therefore, the finishing material 10 of claim 1 has sufficient adsorption of chemical substances that cause sick house syndrome, is excellent in moisture absorption and desorption, and is also excellent in design.

Now, in order to solve the above-mentioned problem, the means taken by the invention according to claim 2 is about the finishing material 10 of claim 1 above.
“At least one of the substrate 11, the decorative layer 12, the Japanese paper layer 13, and the protective layer 14 is provided with a large number of pinholes 15 having a diameter of 0.1 to 1.0 mm, and the surface area of the substrate 11 is 1 × 10 ^{− 4} to 1% "
It is.

  That is, the finishing material 10 according to this second aspect has pinholes 15 with respect to the substrate 11 to the protective layer 14 as indicated by dotted lines in FIG. 2 (a total of seven types (1) to (7)). Thus, a large number of pinholes 15 in the thickness direction are positively formed. By these pinholes 15, the finishing material 10 can easily come into contact with the outside air, and the air intake property and the moisture absorption / release property are further enhanced. It is a thing.

The pinholes 15 indicated by (1) to (7) in FIG. 2 are formed through the following layers. + (Plus) means that the pinhole 15 penetrates the layer connected by this.
(1) = substrate 11 only (2) = substrate 11 + decorative layer 12 + Japanese paper layer 13
(3) = substrate 11 + decorative layer 12
(4) = substrate 11 + decorative layer 12 + Japanese paper layer 13 + protective layer 14
(5) = decorative layer 12 + Japanese paper layer 13 + protective layer 14
(6) = Decorative layer 12 + Japanese paper layer 13
(7) = decorative layer 12 + Japanese paper layer 13 + protective layer 14

  These pinholes 15 are required to have a diameter of 0.1 to 1.0 mm because the first reason is that each pinhole 15 is formed if the diameter of each pinhole 15 is less than 0.1 mm. This is because not only is difficult, but sufficient air-absorbing and moisture-absorbing / releasing properties cannot be obtained for the formed area. If the diameter of each pinhole 15 is larger than 1.0 mm, not only the rigidity of the finishing material 10 itself is impaired, but also the presence of the pinhole 15 can be seen through the Japanese paper layer 13, which is good in terms of design. Because there is no.

  The depth of the pinhole 15 as described above is preferably about 1/10 to 1/2 of the thickness of the substrate 11, for example. This is because if the depth of the pinhole 15 is smaller than 1/10 of the thickness of the substrate 11, there is not much meaning to be formed, and if it exceeds 1/2, the rigidity of the substrate 11 is impaired. is there.

Further, the total opening area of these pinholes 15 is required to be 1 × 10 ⁻⁴ to 1% of the surface area of the substrate 11, and preferably 0.5 to 1%. This is because if the total opening area of the pinhole 15 is lower than 1 × 10 ⁻⁴ %, sufficient air intake and moisture absorption / release characteristics cannot be obtained, and conversely if it exceeds 1%, the rigidity of the substrate 11 is reduced. It is because it loses.

  In order to form a large number of pinholes 15 as described above, the substrate 11 before the Japanese paper layer 13 is affixed to a roller having a large number of needles standing on the surface or a molded plate having the needles erected on the plate or This can be done easily after passing the decorative layer 12 or after the protective layer 14 is applied. Of course, in which layer the pinhole 15 is to be formed can be easily performed by selecting at which stage it is formed as described above.

  Therefore, the finishing material 10 according to the second aspect exhibits the same function as that according to the first aspect, and in addition to the pinhole 15 formed in the substrate 11, the decorative layer 12, and the protective layer 14, The properties and moisture absorption and desorption are further enhanced.

As described above, first, in the invention according to claim 1,
“A substrate 11 mainly composed of at least one of diatomaceous earth, vermiculite, gypsum slag, ALC powder, calcium silicate, slaked lime, or a mixture thereof, and 50 to 250 g on the surface side of the substrate 11 The decorative layer 12 containing a pigment or dye that is applied at a rate of / m ² and decorates the surface of the substrate 11 is pasted on the decorative layer 12 and has a basis weight of 6 to 100 g / m. ² Japanese paper layer 13 and protective layer 14 applied to the surface of this Japanese paper layer 13 at a rate of 10 to 100 g / m ² ”
Therefore, it is possible to provide a finishing material 10 that has sufficient adsorption of chemical substances that cause sick house syndrome, excellent moisture absorption and desorption, and excellent design. is there.

Moreover, in the invention which concerns on Claim 2, about the finishing material 10 of the said Claim 1,
“At least one of the substrate 11, the decorative layer 12, the Japanese paper layer 13, and the protective layer 14 is provided with a large number of pinholes 15 having a diameter of 0.1 to 1.0 mm, and the surface area of the substrate 11 is 1 × 10 ^{− 4} to 1% "
In addition to exhibiting the same effect as that of the first aspect of the present invention, the moisture absorption and desorption properties and the air intake properties of the finishing material 10 can be further improved.

It is a perspective view of the finishing material which concerns on this invention. It is a partial expanded sectional view of the finishing material. It is an expanded sectional view which shows the prior art.

  Next, the invention according to each claim 1 configured as described above will be described with respect to the finishing material 10 which is the best mode shown in the drawings. The finishing material 10 according to this best mode is related to each of the above claims. It includes substantially all of the invention.

  FIG. 1 is a perspective view of the finishing material 10 according to the present invention as viewed from the front side. In FIG. 1, the finishing material 10 has a pattern of the Japanese paper layer 13 itself and the Japanese paper layer 13 as a watermark. The color of the decorative layer 12 that can be seen is visible. As shown in FIG. 2, the finishing material 10 includes a substrate 11 mainly composed of diatomaceous earth, a decorative layer 12 formed on the surface of the substrate 11, and a Japanese paper layer affixed to the decorative layer 12. 13 and a protective layer 14 applied to the Japanese paper layer 13.

  The substrate 11 in the best mode is mainly composed of diatomaceous earth, but may be formed by adding pulp fibers or gypsum to the diatomaceous earth. Of course, the substrate 11 may have a shape-retaining paper (not shown) attached to the back surface thereof, and has a certain degree of rigidity due to the shape-retaining paper and mixed pulp fibers.

  The substrate 11 of the best mode has a thickness of 3 to 15 mm, and as shown by the dotted line in FIG. 2, a large number of pinholes 15 having a depth of 5 × 1/3 mm are used as finishing materials. 10 in the thickness direction. These pinholes 15 are formed by using a roller in which a needle having a thickness of 0.5 mm and a length of 5 × 1/3 mm is implanted on a grit or a molding plate in which needles are erected on a plate. In this case, the lattice width was 5 mm.

The decorative layer 12 was formed by applying a paint having an acrylic emulsion resin and a pigment to the surface of the substrate 11 as described above with a roller. The application amount in this case was 80 g / m ² , and the thickness of the decorative layer 12 was set to be about 50 μm to 100 μm.

On the decorative layer 12 formed in this way, a Japanese paper layer 13 was formed by sticking Japanese paper formed with half-colored materials of mulberry and rayon. This Japanese paper layer 13 has a basis weight of 18 g / m ² .

  And the protective layer 14 was formed in the surface of this Japanese paper layer 13 by apply | coating the clear coating material which used acrylic emulsion resin for the purpose of adhesion | attachment and protection as a main material with an automatic coating machine (roll coater).

As a result of an experiment based on JIS A 14710-1 (constant temperature at 23 ° C., 90% rh atmosphere), the finishing material 10 without blank diatomite substrate of 375.55 g / m ² and the decorative layer 12 was 256.87 g. / M ² , the finishing material 10 for all processes was 213.10 g / m ² .

  As a result of the above, not only the finish material 10 in which the natural beauty of the Japanese paper layer 13 has appeared, but also the decoration of the decorative layer 12 on the substrate 11 while watermarking each fiber of the Japanese paper grass 13, As shown in FIG. 1, it appeared in a delicate state.
