DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative material, and more particularly to a decorative material having a deodorizing function which is used as a surface decorative material for building interior members made of various materials.

[0002]

2. Description of the Related Art Conventional decorative materials, such as wall materials, floor materials, and ceiling materials, are provided with a desired pattern printing or irregular pattern on a base material such as paper or resin in order to impart a design property. Was used. Further, a decorative material which has been subjected to a surface treatment comprising a transparent resin layer for imparting durability and stain resistance to a printed pattern or a concavo-convex pattern of the decorative material has been used.

Various decorative materials as described above are bonded to members made of various materials, such as plywood, laminated wood, woody materials such as particle board, inorganic materials such as gypsum board, metal, synthetic resin, and the like. Widely used as interior members.

[0004]

Incidentally, in the conventional cosmetic materials, in recent years, cosmetic materials having various functions such as deodorant and antibacterial have been demanded. In addition to the applied decorative material, examples of the decorative material having functions such as deodorization of indoor air, ionization of air, purification, and antibacterial property include, for example, wallpaper and wall members described in JP-A-10-46479. This wallpaper, on a paper substrate,
In a wallpaper having a resin layer and a pattern printing layer, a paper substrate,
It is characterized in that at least one of the resin layer or the pattern printing layer contains tourmaline powder. Tourmaline is a silicate mineral, has a spontaneous polarization of electric charge,
Further, it has a property of exhibiting a piezoelectric effect and a pyroelectric effect, and is known to decompose organic substances and have a deodorizing function.

Japanese Patent Application Laid-Open No. H10-100333 discloses that a pattern printing layer and a transparent resin layer are sequentially formed on a sheet-like substrate such as paper, and at least one of these layers is provided with dicyandiamide or the like. A decorative sheet containing a formaldehyde scavenger comprising an organic amino compound or the like is described. This decorative sheet has a function of capturing and removing formaldehyde released from the wood plywood into the room.

Further, Japanese Patent Application Laid-Open No. 10-58588 describes a decorative material having a transparent anatase type titanium dioxide layer formed on a base material via a transparent inorganic material layer.
This cosmetic material has a function of photodecomposing and removing odor components such as formaldehyde present in the air.

Further, utility model registration No. 30418
No. 03 discloses a cosmetic material obtained by mixing and adding both tourmaline and anatase type titanium dioxide to paper.

However, all of the above-mentioned conventional cosmetic materials having a deodorizing function chemically decompose organic substances or decompose them by trapping them in the cosmetic material, but the effect is sufficient. Absent. In particular, in the case of a cosmetic material configured to capture and remove formaldehyde using an organic amino compound, it utilizes the fact that the organic amino compound reacts with the aldehyde to change into a Schiff base and water, but this reaction is a reversible reaction. For this reason, when the indoor humidity is high, the aldehyde once trapped is released again, and the aldehyde trapping effect may be reduced. However, a cosmetic material that controls indoor humidity to a low level and sufficiently captures organic substances such as aldehydes to exhibit a deodorizing function has not yet been known.

[0009] Therefore, an object of the present invention is to provide a cosmetic material having an extremely high deodorizing function by capturing organic substances such as aldehydes, which are odor sources.

[0010]

Means for Solving the Problems To achieve the above object, a cosmetic material of the present invention has a deodorizing layer containing a substance capable of forming an aldehyde and a Schiff base and a synthetic zeolite having a faujasite structure. It is characterized by.

As a result of intensive studies, the present inventor has found that an excipient containing a substance capable of forming a Schiff base with an aldehyde and a synthetic zeolite having a faujasite structure having a humidity control function, particularly a function of absorbing moisture under high humidity. The present inventors have found that a cosmetic material having an odor layer exhibits a remarkably excellent deodorizing function, and have completed the present invention.

It is known that the performance of the deodorizing function is also affected by humidity, and in particular, in the case of deodorizing by capturing aldehyde, the performance is generally improved under low humidity. However, the relationship between aldehyde scavenging ability and humidity is explained as follows.

That is, an aldehyde represented by the general formula R ¹ CHO is composed of an organic substance represented by the general formula R ² NH ₂ and a Schiff base (having a —CH ＝ N— structure in the molecule) as shown in the following formula. A compound having). Where R ¹ and R ²
Is a monovalent substituent.

[0014]

Embedded image R ¹ CHO + R ² NH ₂ ← → R ¹ CH
= NR ² + H ₂ O

The above reaction is an equilibrium reaction, and according to the above reaction formula, one molecule of water is generated simultaneously with the formation of the Schiff base. Therefore, when the humidity is lower (the water content is lower), the equilibrium is shifted to the right side, and the aldehyde capturing ability can be enhanced.

[0016] In the cosmetic material of the present invention, in the deodorant layer,
It contains a synthetic zeolite having a faujasite structure having a humidity control function, particularly a function of absorbing moisture under high humidity, in addition to the substance capable of forming a Schiff base with the aldehyde. Therefore, the adsorption of water by the synthetic zeolite having the faujasite structure promotes the bias of the above reaction formula to the right side, and the environment is set to a low humidity of a certain level or less, and aldehyde, which is a main odor source in the room, is shuffled. The function of capturing and deodorizing as a base can be extremely enhanced.

Further, the synthetic zeolite having a faujasite structure having a moisture absorbing function adsorbs not only the above-mentioned water but also other malodor sources such as pyridine.
It also has a deodorizing function.

Therefore, according to the present invention, it is possible to provide a cosmetic material having an extremely high deodorizing function by trapping an organic substance such as aldehyde which is an odor source.

In the above-mentioned decorative material of the present invention, the first deodorant layer containing a substance capable of forming an aldehyde and a Schiff base and the second deodorant layer containing a synthetic zeolite having a faujasite structure are used as the deodorant layer. It is preferable to form a structure in which the deodorizing layer is laminated as a separate layer from the viewpoint of exhibiting an excellent deodorizing function.

Since the above reaction for trapping aldehyde is an equilibrium reaction, a reverse reaction proceeds to the left side under acidic or alkaline conditions, and the Schiff base is hydrolyzed to form a compound with the compound represented by the general formula R ² NH _2. Aldehyde, which is an odor source, is generated (re-released). In addition, H-type synthetic zeolite having a faujasite structure (synthetic zeolite having a faujasite structure subjected to ion exchange treatment with ammonium ions) has a deodorizing performance depending on acidity, but is useful for trapping aldehydes. When coexisting with a substance having a group in the same layer, there is a possibility that the deodorizing performance of each may be negated. However, the first deodorant layer containing a substance capable of forming an aldehyde and a Schiff base and the second deodorant layer containing a synthetic zeolite having a faujasite structure are formed as separate layers, respectively.
The water adsorbed on the synthetic zeolite having the faujasite structure is suppressed from being subjected to the hydrolysis of the Schiff base without canceling the deodorizing performance of each of the deodorizing layer and the second deodorizing layer. , The progress of the equilibrium of the above reaction formula to the left side can be suppressed.

In the above-described decorative material of the present invention, it is preferable that the first deodorant layer is formed so as to have a smaller total area than the second deodorant layer. . When the total coverage of the first deodorant layer containing a substance capable of forming an aldehyde and a Schiff base is greater than the coverage of the second deodorant layer containing a synthetic zeolite having a faujasite structure, Water in the air and water generated by the formation of Schiff bases (trapping of aldehydes) may be adsorbed and saturated, and may not be able to adsorb other odor sources such as pyridine. If the source material and the moisture in the air are first adsorbed and saturated, the moisture generated in the first deodorizing layer cannot be adsorbed, and the aldehyde capturing ability is reduced. By setting the total covering area of the first deodorizing layer to be smaller than the covering area of the second deodorizing layer, it is possible to suppress the above-described problem of the adsorption saturation of moisture, pyridine, and the like. Can .

In the above-described decorative material of the present invention, the second deodorant layer is preferably a layer further containing a metal oxide. With the cosmetic material of the present invention having such a configuration, the metal oxide serves as a catalyst for decomposing an organic substance serving as a malodorous source such as an aldehyde adsorbed and captured by the synthetic zeolite, thereby increasing a deodorizing rate, It is possible to increase the capacity for holding malodor source substances such as pyridine.

Here, the deodorizing mechanism of the cosmetic material of the present invention is shown in FIG.
This will be described with reference to FIG. The cosmetic material Z shown in FIG. 1 is a substance capable of forming a Schiff base S with an aldehyde A (shown by a circle in the figure).
And a second deodorant layer Y containing a synthetic zeolite having a faujasite structure (indicated by △ in the figure). Here, the coverage area of the first deodorant layer X is formed smaller than the coverage area of the second deodorant layer Y, and the first deodorant layer X is covered by the second deodorant layer Y. It has a broken structure.

As a deodorizing mechanism for aldehyde and the like, first, an odor source such as aldehyde A and pyridine P contained in the air adheres to the cosmetic material Z and is taken in. Aldehyde A that has diffused in the layer and reached the first deodorant layer X reacts with a substance capable of forming a Schiff base S with the aldehyde A (indicated by a circle in the figure) and is captured in the form of a Schiff base S. You. At this time, one molecule of water W is generated at the same time, and this water is adsorbed on the synthetic zeolite having a faujasite structure contained in the second deodorant layer Y (indicated by △ in the figure).

In the above reaction, part of the synthetic zeolite having the faujasite structure adsorbs water W and saturates (indicated by ▲ in the figure), but the coverage area of the second deodorant layer Y is the first area. Is larger than the area covered by the deodorant layer X, the synthetic zeolite having the unsaturated faujasite structure is sufficiently present inside the layer.

On the other hand, organic substances having a bad odor such as pyridine P other than aldehydes are adsorbed on synthetic zeolite having a faujasite structure whose adsorption is unsaturated. In FIG. 1, only pyridine P is depicted as a malodor source organic substance other than the aldehyde, but other malodor source organic substances such as acetic acid and toluene are also adsorbed to the synthetic zeolite having a faujasite structure similarly to pyridine. . In the above reaction, a part of the synthetic zeolite having the faujasite structure is saturated by adsorbing a malodor source organic substance such as pyridine P (indicated by ΔP in the figure).

As explained above, the cosmetic material of the present invention
It has the function of very efficiently adsorbing and deodorizing organic substances offensive odors such as aldehydes and pyridine.

[0028]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the decorative material of the present invention will be described in detail. [Substance capable of forming an aldehyde and a Schiff base] The deodorant layer of the cosmetic material of the present invention contains a substance capable of forming an aldehyde and a Schiff base. As the substance capable of forming a Schiff base with the aldehyde, for example, the following compounds can be used.

1. <Hydrazide compound> As a substance capable of forming a Schiff base with an aldehyde contained in the deodorant layer of the cosmetic material of the present invention, one or more compounds having a hydrazide group (—NHNH ₂ group) in the molecule are used. Mixtures can be used.

As the compound having a hydrazide group in the molecule, for example, a dihydrazide compound having two or more hydrazide groups in the molecule can be preferably used. Such dihydrazide compounds include, for example, linear oxalic acid dihydrazide such as oxalic acid dihydrazide, malonic acid dihydrazide, adipic acid dihydrazide, succinic acid dihydrazide, glutaric acid dihydrazide, pimelic acid dihydrazide, suberic acid dihydrazide, azelaic acid dihydrazide, and sebacic acid dihydrazide. And aromatic dihydrazide compounds such as terephthalic acid dihydrazide and isophthalic acid dihydrazide, and polymer type hydrazide compounds such as polyacrylic acid hydrazide.

The hydrazide compound is preferably a water-soluble hydrazide compound from the viewpoint of environmental problems. Of these,
Adipic dihydrazide and polyacrylic hydrazide alone or in combination are particularly preferred.

The hydrazide compound can be used as a crosslinked product by reacting with a polyfunctional monomer. In this case, as the hydrazide compound, it is preferable to use a hydrazide compound such as an isocyanate compound or an epoxy compound by performing a crosslinking reaction with a polyfunctional monomer (crosslinking agent) having two or more functional groups that react with the hydrazide group. .

2. <Chitosan> As a substance capable of forming a Schiff base with an aldehyde contained in the deodorant layer of the cosmetic material of the present invention, a polymer having an amino group in the molecule such as chitosan having a relatively large molecular weight can be preferably used. . Chitosan is a polysaccharide having an amino group and having a glucosamine unit as a main constituent unit, and is a polymer obtained by deacetylating chitin present in crustaceans such as crabs and shrimps. Those having a degree of deacetylation of about 70 to 90% are commercially available. The molecular weight is not particularly limited as long as the molecular weight is about 1,000,000 to tens of thousands.

In addition, a resin having chitosan forming a complex with the carboxyl group and binding to the carboxyl group-containing resin, or mixing the complex with an aqueous emulsion resin or the like, followed by drying and immobilization can also be used.

3. The substance capable of forming an aldehyde and the Schiff base is caused to contain a deodorant layer of decorative material of the present invention <Compound having other amino group (-NH ₂ group)>, amino groups in the molecule (-NH ₂ group) Or a mixture of two or more compounds having the following formula:

Examples of the compound having an amino group in the molecule include dicyandiamide, melamine, urea, barbituric acid, semicarbazide hydrochloride, glutamic acid,
Substances such as glycine and alanine can also be used.

[Other deodorants] <Synthetic Zeolite with Faujasite Structure> The deodorant layer of the cosmetic material of the present invention needs to contain a synthetic zeolite with a faujasite structure as another deodorant. _{Zeolite, Na 2 O · Al 2 0} 3 · xS
It is represented by iO ₂ .nH ₂ O (x is 2 to 6), and the faujasite structure has a molecular structure having vacancies having an inlet diameter of about 8 Å.

Here, the faujasite zeolite is generally synthesized in the form of Na, but by ion exchange with ammonium ions, alkaline earth metal ions such as calcium and magnesium, and rare earth metal ions such as lanthanum and cerium. , H-type, Ca-type, La-type, etc. These solid acids of ion-exchanged zeolites have high catalytic activity for catalytic cracking of petroleum and are widely used.

As the decorative material of the present invention, a zeolite powder having a faujasite structure can be carried on a substrate. In order to carry the zeolite, usually, the zeolite powder is dispersed in a binder of an appropriate resin, and laminated on a substrate by a coating method or the like. In particular, a Y-type synthetic zeolite having a faujasite structure converted to an H-type (exchanged with ammonium ions) has a good deodorizing performance against alkaloid components such as pyridine, probably because of its strong polarity,
preferable.

Generally, the zeolite having the faujasite structure has uniform and extremely fine pores, and exhibits excellent adsorptivity to gas and liquid. Although the details of the deodorizing mechanism of this material have not been elucidated yet, it is considered that there are many places that contribute to the surface activity and the increased surface area by being made porous, and it is considered that the larger the specific surface area, the better. Of course, in addition to the H type, those of the Ca type (ion exchange with calcium ions) and La type (ion exchange with lanthanum ions) can also be used. As a zeolite, besides Y type, X
Types can also be used.

Also, since these zeolites alone cannot be expected to have the effect of decomposing odorous components, Cu, F
transition metal oxides such as e and Zn, and anatase type Ti
It is preferable that a photocatalyst represented by O ₂ or the like be supported in zeolite or be present near zeolite.
When this zeolite is used in the deodorizing layer, an effect of greatly increasing the capacity for retaining the target odor component can be expected in addition to the deodorizing speed conventionally expected. Also, this zeolite only needs to be on the outermost surface of the cosmetic material,
In order to further increase the consumption, it may be mixed in the interior of the decorative material. Resin such as polyacrylic acid and ethylene-vinyl acetate copolymer can be used as a binder in this deodorant layer, and a foaming agent such as a capsule foaming agent that is usually used is mixed in, and heated to a foaming temperature after film formation. And may be foamed.

2. <Metal Oxide> Further, in the decorative material of the present invention, it is more preferable that the deodorant layer carries a metal oxide having a function of decomposing organic substances. Synthetic zeolite with faujasite structure has the function of adsorbing water and various organic substances,
It has no function to decompose organic substances that are odor sources. Therefore, by allowing the metal oxide to be present in the vicinity of the synthetic zeolite having the faujasite structure, the organic substance is adsorbed,
It can be decomposed to further enhance the deodorizing effect.

Further, by coexisting a synthetic zeolite having a faujasite structure and a metal oxide, the capacity for adsorbing and holding an organic substance to be deodorized is greatly increased in addition to the quick deodorizing action expected conventionally. Can be increased.

Such metal oxides include Cu, Fe,
Examples thereof include oxides of transition metals such as Zn, and photocatalysts represented by anatase-type titanium oxide (TiO ₂ ). These function as catalysts when decomposing organic substances.

3. <Other zeolites> In addition to a substance capable of forming an aldehyde and a Schiff base and a synthetic zeolite having a faujasite structure, the cosmetic material of the present invention may further include, if necessary, aluminum or magnesium to further enhance the deodorizing function. Zeolite obtained by calcining a composite of a metal salt such as zinc and the like can be further added. If necessary, it is preferable to further add another metal oxide such as iron oxide, zinc oxide, or copper oxide to the zeolite as a catalyst for the organic low-molecular decomposition reaction.

Since zeolite has both a basic group and an acidic group, it has the ability to adsorb both a basic malodorous source decomposition product and an acidic malodorous source decomposition product. The adsorbed malodor source organic substance or malodor source decomposition product is gradually decomposed by the action of the metal oxide in the deodorant layer and the substance capable of generating aldehyde and Schiff base. For example, when ammonia is decomposed into nitrogen and water using a metal oxide such as zinc peroxide as a catalyst, and hydrogen sulfide is decomposed to generate hydrogen while being replaced with a metal sulfide using a metal oxide as a catalyst. It is considered.

By including one or more of the above substances having a deodorizing function in a cosmetic material, it is possible to effectively deodorize malodorous substances containing many organic substances such as tobacco odor. can do.

[Deodorizing Layer] In the deodorizing layer of the cosmetic material of the present invention, a substance capable of forming a Schiff base with an aldehyde (for example, an organic compound having an amino group) and a transition metal catalyst are not present in the same system. The effect can be more exhibited. In addition, there is a preferable combination in which other deodorants are used without being mixed with each other without canceling out the effects of each other. Examples of such a combination of deodorants include an amino group containing chitosan or a hydrazide. The deodorant selected from the group-containing compound or tourmaline and the deodorant selected from the photocatalyst, alkyl carboxylate, transition metal oxide or activated clay exist in the same system. It is preferable not to let them.

A zeolite having a faujasite structure has no offsetting effect even when mixed with the substance capable of forming a Schiff base with an aldehyde (for example, an organic compound having an amino group), but rather contains an amino group. It is effective because it suppresses the reverse reaction (reaction in which the aldehyde is formed by hydrolysis of the Schiff base) by adsorbing water, which is a by-product of the reaction in which the organic compound reacts with the aldehyde and decomposes into a Schiff base and water. . However, in order to achieve both the decomposition action of the aldehyde in organic amino and the adsorption and decomposition of other odor components in zeolite without competing with each other, the organic amino layer and the zeolite layer are formed as a laminate of another adjacent layer. Further, it is preferable that the area of the zeolite-containing layer having the faujasite structure is made larger so that the effects of adsorbing aldehydes and other substances can be achieved without competing with each other. In addition, the effect of removing water at the time of organic amino decomposition is also compatible.

In the decorative material of the present invention, since the deodorant itself has no self-supporting property, the composition obtained by adding the above-mentioned deodorant to a resin binder is applied, melt-extruded, It is preferable to form and form a film by a method such as calendering.

As the resin binder, various resins can be used without any particular limitation. Further, a combination of the resin composition and a film forming method, a drying and solidification of an emulsion using a diluent obtained by diluting in an organic solvent or an aqueous dispersion medium, and a cooling and solidification of a melt can be used.

However, from the viewpoint of sufficiently exhibiting the deodorizing function, the deodorizing layer is formed from a resin composition which is not dissolved in an organic solvent but is dissolved or emulsified in water or a water-alcohol solvent or the like. Is preferred. In addition, when mixed with an aqueous emulsion, harmful substances such as solvents do not volatilize during processing,
It is also preferable in terms of environmental pollution and working environment.

As the emulsion, there is a technique in which formalin is added to the system for the purpose of effectively drying and curing the resin. However, it is more preferable to use a non-formaldehyde type emulsion in view of the so-called house-sick problem.

If these conditions are satisfied, the emulsion itself is not particularly limited, but examples thereof include an acrylic resin, an acrylic-styrene copolymer, an ethylene-vinyl acetate copolymer, a polyolefin resin, and a urethane resin. Emulsions can be used. These resins are resins containing no chlorine and are particularly preferable because no harmful hydrogen chloride gas or the like is generated during disposal or incineration.

As such a resin, more specifically,
Licabond ET83 which is an acrylic-styrene copolymer
(Trade name of Chuo Rika Kogyo Co., Ltd.), Ricabond ET84 which is an acrylic copolymer (trade name of Chuo Rika Kogyo Co., Ltd.), Aquatex MC-3800 which is an ethylene-vinyl acetate copolymer (Chuo Rika Kogyo Co., Ltd.) (Product name),
Aquatex M, an ethylene-vinyl acetate copolymer
Examples thereof include C-3500 (trade name of Chuo Rika Kogyo Co., Ltd.) and Aquatex MA-20 (trade name of Chuo Rika Kogyo Co., Ltd.) which is an ethylene-based terpolymer. Alternatively, a silicone resin such as KM2002T (trade name of Shin-Etsu Chemical Co., Ltd.) can be used.

To the above-mentioned deodorant-containing resin composition, a colorant such as a pigment or a dye can be appropriately added in order to impart a desired color and / or hiding property.
The coloring may be either transparent coloring or opaque coloring (concealment).

Examples of the coloring agent include inorganic pigments such as titanium white, zinc white, red iron oxide, vermilion, ultramarine blue, cobalt blue, titanium yellow, carbon black, isoindoline, Hansa Yellow A, quinacdrine, permanent red 4R, phthalocyanine blue and the like. Organic pigments, dyes, metal pigments made of foil powder such as aluminum and brass, pearlescent pigments made of foil powder such as titanium dioxide-coated mica, and basic zinc carbonate, and the like.

The thickness of the deodorizing layer is not particularly limited as long as it is a film thickness sufficient to sufficiently exhibit the deodorizing function.
In consideration of the production cost and processability of the cosmetic material, the coating amount of the deodorant-containing resin composition is usually 0.01 to 20 g / m ^2.
The degree is preferred.

In forming the deodorant layer, a foaming agent or the like is mixed into the deodorant layer in order to increase the surface area of the deodorant and further increase the deodorizing efficiency, and the foam is formed by heating to a predetermined temperature. The foam can be formed to increase the surface area of the deodorant layer.

As the blowing agent, azodicarbonamide,
Thermal decomposition type such as oxybisbenzenesulfonyl hydrazide, and microcapsule type in which low boiling point substances such as pentane, hexane and butane are sealed in the spherical shell of resin such as polyacrylonitrile and polyvinylidene chloride can be used. .

The deodorant layer can be formed by coating or laminating the above-mentioned deodorant-containing composition by an ordinary bar coat, gravure coat, roll coat, screen printing or the like, or a combination thereof. .

[Cosmetic Material] The layer structure of the cosmetic material of the present invention includes:
There is no particular limitation as long as it has a deodorizing layer containing a substance capable of forming a Schiff base with an aldehyde and a constituent zeolite having a faujasite structure.
