[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention is a single-layer or multiple-layer capable of easily and efficiently adsorbing and removing components to be adsorbed such as odor components such as carbonyl group-containing compounds such as aldehydes and ketones and odorless harmful gas components. relates to a method of producing an adsorption processing member, this technique can be effectively used in the adsorption treatment, especially in a room of an automobile, housing-house.
[0002]
[Prior art]
As a method for removing odor components in gas, in the case of large-scale equipment such as sewage treatment equipment and municipal solid waste incineration equipment, sprinkling cleaning equipment using cleaning water or the like in which a chemical having reactivity with odor components is dissolved, etc. Is used. However, in the case of performing the adsorption treatment in a limited space such as a toilet, a room, or a vehicle interior, a large-scale water sprinkling washing facility cannot be provided. Adsorption treatment methods using chlorination are widely used.
[0003]
On the other hand, in the interior of a vehicle such as an automobile, decomposition gases such as fuels and oils, combustion products derived from tobacco, adhesives used for bonding interior boards and in-vehicle equipment, and foaming resins for heat insulation are volatilized. It has been confirmed that malodorous or odorless toxic gas components such as organic compounds are present. Houses and houses also contain harmful gas components, as well as combustion products derived from tobacco, as well as sick houses due to harmful substances volatilizing from insulation materials, plywood materials, adhesives, etc. ing.
[0004]
Among these odorous or odorless toxic gas components (hereinafter sometimes simply referred to as gas components), carbonyl group-containing compounds such as formaldehyde, acetaldehyde, acrolein and benzaldehyde are contained. However, activated carbon alone, which is a physical adsorbent used in air purifiers and the like, usually has insufficient adsorption removal ability of these compounds.
[0005]
In addition, physical adsorbents such as activated carbon exhibit adsorption removal ability by trapping components to be adsorbed in adsorption sites, but also adsorb moisture (moisture) in the gas to be treated. When the adsorption site is saturated with moisture, the adsorption performance is no longer exhibited.
[0006]
Therefore, various studies have been made on an adsorbent capable of adsorbing and removing a gas component even in a room or a car room where moisture is present. The present applicant has found a phenolic compound capable of reacting with the carbonyl compound in the presence of moisture, and has already filed an application for a composition containing a water-absorbing substance for supporting the compound (Japanese Patent Application No. 10-271386). .
[0007]
The composition for adsorption treatment is preferably in the form of powder or granules in order to secure the surface area required for the adsorption treatment, but it is difficult to apply the powder or granules to an adsorption treatment device or an air cleaning filter. Therefore, it is usually used sandwiched between gas-permeable materials such as nonwoven fabrics. At this time, in consideration of gas permeability, if a small (coarse) gas-permeable material having a basis weight (weight per unit area: g / m 2) is used, if the composition for adsorption treatment is fine, There is a problem in that the material may be desorbed from the gas passage hole and lose commercial value or may not be able to exhibit sufficient adsorption performance.
[0008]
Attempts have been made to make the composition for adsorption treatment into secondary particles with a large particle size. However, when the particle size is made large, the surface area required for the adsorption treatment is reduced, so that the adsorption efficiency is reduced. When the binder resin covers the surface of the composition for adsorption treatment, the adsorption performance may be hindered.
[0009]
[Problems to be solved by the invention]
For this reason, there is a demand for a method of forming a sheet shape that does not cause desorption of adsorbent particulates and that can be used as a filter or the like while securing a surface area required for the adsorption treatment.
[0010]
Thus, in the present invention, a method for manufacturing an adsorption treatment member that can be easily formed into a sheet without impairing the adsorption performance is established, and an adsorption treatment member that can achieve both good adsorption performance and adhesiveness is provided. The task was to provide.
[0011]
[Means for Solving the Problems]
This onset Ming, the spraying on the substrate, while spraying the first adsorbent zeolite having an average particle diameter 400～600Myuemu, an adhesive is applied to the first sheet-like member, the adhesive is applied The first sheet-like member and the zeolite-based first adsorbent are fixed by placing the first sheet-like member on the sprayed first adsorbent and adhering the adhesive and the first adsorbent. and a method of manufacturing the adsorption processing member, such that the adhesive weight applied to the first sheet-shaped member, and 10 to 60 wt% of zeolite weight fixed to the first sheet-like member on the The amount of the adhesive and the amount of zeolite are adjusted.
[0012]
By employing this configuration, the zeolite-based adsorbent could be firmly bonded to the sheet member. In addition, since there is no extra adhesive that covers the surface of the adsorbent and hinders the adsorption performance, excellent adsorption performance is exhibited.
[0013]
The first sheet-shaped member is preferably a nonwoven fabric made of fiber. In this case, when the average diameter of the fibers forming the nonwoven fabric is X (μm) and the basis weight of the nonwoven fabric is Y (g / m ² ), It is recommended that the adhesive weight W be adjusted so as to satisfy the following formula, so that both adsorption performance and adhesiveness can be achieved.
W = W ₀ × (Y / 30) × (18 / X)
However, W ₀ is 10 to 60 g / m ^2.
[0014]
Although the above-mentioned member for adsorption treatment can be used as it is in a casing, it can also be used as a member for adsorption treatment of a multilayer type using the second sheet. As the multi-layer type adsorption member, the first and second sheet members are formed by laminating the second adsorbent and the second sheet member on the single-layer type adsorption member. It has a configuration in which a zeolite-based first adsorbent and a second adsorbent are sandwiched, and at least one of the first and second sheet members has air permeability. The combination of two types of adsorbents and the use of the sandwiching structure provide an adsorption processing member capable of adsorbing various kinds of components to be adsorbed with a simple configuration.
[0015]
The zeolite-based first adsorbent has a structure in which an adsorbent compound that reacts with the component to be adsorbed in the presence of moisture is supported on the zeolite surface, and the component to be adsorbed contains a carbonyl group. A compound wherein the adsorptive compound is at least one compound selected from the group consisting of monohydric phenols, polyhydric phenols and derivatives thereof, and a structure wherein the zeolite is an H-type zeolite. 1 is a preferred embodiment of the adsorbent.
[0016]
A configuration in which the second adsorbent is a physical adsorbent, particularly a configuration in which the second adsorbent is at least one selected from the group consisting of activated carbon, silica gel, alumina, bentonite, diatomaceous earth, and bauxite, is preferable for the second adsorbent. It is an embodiment.
[0017]
In the case of a multi-layer type member for adsorption treatment, the adsorption treatment is possible if any of the first and second sheet members has air permeability. It is preferable because efficiency can be improved. Furthermore, it is recommended to use a nonwoven fabric as the first and second sheet-shaped members because they are inexpensive and can be widely selected from those having various strengths and basis weights according to applications. In addition, in order to increase the strength of the adsorption processing member, it is preferable to adopt a configuration in which the sheet members are intermittently joined.
[0018]
In the case of manufacturing a multilayer type member for adsorption treatment, it is easy to adopt a method in which a second sheet-like member to which a second adsorbent is fixed in advance is used as a base for spraying in the above-described production method. Further, after placing the first sheet-like member to which the adhesive has been applied on the second sheet-like member to which the second adsorbent is fixed in advance and the zeolite-based first adsorbent is sprayed, If a method of intermittently joining the first and second sheet-like members by applying heat and pressure is employed, the first and second sheet-like members are less likely to be peeled off, and are used for an adsorption treatment which has high strength and excellent workability. A member can be provided.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
The member for adsorption treatment produced by the production method of the present invention has a sheet shape so that it can be used alone or loaded in a casing or the like to be used as an adsorption treatment device or an air cleaning filter. In consideration of the efficiency of the adsorption treatment, the adsorbent is preferably a fine granular material having a large surface area. However, when an adhesive is used to make the granular material into a sheet, the surface of the adsorbent is covered with the adhesive and the adsorption performance is impaired.
[0020]
Therefore, the present inventors have limited the first adsorbent to zeolite-based, and as a result of examining the relationship between the adsorption efficiency and the average particle diameter, the particle size conditions that can be fixed to the sheet-like member with an appropriate amount of adhesive, and the like, It has been found that good adsorption efficiency and adhesion performance can be obtained by fixing a zeolite-based adsorbent having an average particle size of 400 to 600 μm to a sheet-like member with an adhesive of 10 to 60% by weight of the zeolite weight. Invented the invention. Hereinafter, the present invention will be described in detail.
[0021]
The member for adsorption treatment produced by the production method of the present invention includes a single-layer type comprising a first sheet-like member and a zeolite-based first adsorbent, and a first and second adsorbent comprising first and second sheet-like members. Is divided into a multi-layered type with a configuration sandwiched between them.
[0022]
In any of the single-layer and multi-layer types, the zeolite-based first adsorbent is fixed to the first sheet member with an adhesive of 10 to 60% by weight of the zeolite weight. The weight of the adhesive applied to the first sheet member should be 10 to 60% by weight of the weight of the zeolite fixed to the first sheet member. Whether or not it falls within this range is determined by measuring the weight of the zeolite and the amount of the adhesive present in the cut-off portion when an arbitrary area (without considering the thickness) of the adsorption treatment member is cut out. It can be determined by the following.
[0023]
When the amount of the adhesive is less than 10% by weight of the weight of the zeolite, the adhesive force of the first adsorbent to the first sheet member is weak, and a desired amount of the first adsorbent can be fixed to the first sheet member. As a result, only a member for adsorption treatment having poor adsorption ability can be obtained. If an adhesive exceeding 60% by weight is used, excess adhesive adheres to the surface of the first adsorbent and closes the pores of zeolite, which is an adsorption site, so that the adsorption capacity is also lowered. The amount of the zeolite-based first adsorbent can be appropriately increased or decreased according to the use, the concentration of the substance to be treated, and the like, but is preferably about 30 to 300 g / m ² per unit area of the first sheet member. preferable.
[0024]
FIG. 1 is a cross-sectional explanatory view of a typical example of a single- layer member for adsorption treatment. The adsorption treatment member 1 is configured by fixing a zeolite-based first adsorbent 21 on a first sheet-shaped member 31 with an adhesive 41. When the first adsorbent 21 overlaps a plurality of stages in the thickness direction of the adsorption processing member 1 (vertical direction in FIG. 1), it becomes difficult for the gas to be treated to flow, and the first adsorbent 21 is bonded with an adhesive without covering the surface of the adsorbent. Therefore, in the member for adsorption treatment of the present invention, it is recommended to adopt a configuration in which the first adsorbent is fixed to the surface of the first sheet member only in one stage. However, it is allowable in manufacturing that the first adsorbent partially overlaps two or more stages. Further, in the case of the member for multilayer adsorption treatment, there is no inconvenience even if the adsorbent has two or more stages due to the presence of the first sheet-like member, the second sheet-like member, and the space therebetween.
[0025]
In the single-layer member 1 for adsorption treatment, since the first adsorbent 21 is exposed on the surface of the member 1, the first adsorbent 21 and the gas to be treated come into direct contact with each other by being loaded in a casing or the like. In order to obtain, the first sheet-like member 31 does not need to be air-permeable. Accordingly, plastic sheets, various plate materials, and the like can be used. However, in consideration of the efficiency of the adsorption treatment, the gas to be treated can pass from the first sheet-like member 41 side and come into contact with the first adsorbent 21. Is more preferred. Therefore, as the first sheet-like member 41, it is recommended to use a gas-permeable material such as paper, nonwoven fabric, or a mesh of various materials.
[0026]
In particular, it is preferable to select a nonwoven fabric material because it is inexpensive, lightweight, and has a wide range of strengths and basis weights depending on the application. As the nonwoven fabric, a nonwoven fabric having a basis weight (basis weight) of 10 to 200 g / m ² may be used, and a filter grade for dust removal or the like is particularly preferable. Non-woven fabric materials include natural fibers, synthetic fibers such as polyethylene, polypropylene, polyester, and nylon; polymer fibers such as composite fibers obtained by compounding these materials in a core-sheath or side-by-side; and non-polymer fibers (metal, carbon, etc.). Can be used.
[0027]
FIG. 1 shows an example in which the adhesive 41 is intermittently applied to the first sheet-shaped member 31. However, as long as the above-described amount limitation is satisfied, even if the first sheet-shaped member is entirely coated, the streaks are applied. However, dot coating may be used. The coating method is not particularly limited, and roll coating, spray coating, nozzle coating, and bar coating can be employed.
[0028]
Examples of the adhesive include vinyl acetate resins such as polyvinyl acetate and vinyl acetate-ethylene copolymer (EVA); acrylic resins such as (co) poly (meth) acrylate; polyurethane resins; polyester resins; polyolefin resins; Styrene resins such as SIBS and SIBS; rubbers such as natural rubber and synthetic rubber; polyvinyl alcohol; and other known adhesives can be used. The adhesive of the present invention includes not only an adhesive which is completely cured by a thermosetting reaction or the like but also a pressure-sensitive adhesive, a so-called pressure-sensitive adhesive. The adhesive may be any of an emulsion type, a solvent (water or organic solvent) type, a non-solvent type, and a hot melt type.
[0029]
When a nonwoven fabric is selected as the first sheet-like member, the adhesive may permeate into the nonwoven fabric and may not contribute to the adhesion of the adsorbent, but the amount of the adhesive is 10 to 60% by weight of the zeolite amount. If so, it shows good adhesiveness. It is preferable that the zeolite is applied in an amount of 30 to 300 g / m ² per unit area of the first sheet-shaped member. Become.
W = W ₀ × (Y / 30) × (18 / X)
However, W ₀ is 10 to 60 g / m ^2.
[0030]
Here, X is the average diameter (μm) of the fiber forming the nonwoven fabric, and when the cross section of the fiber is not circular, it is the radius of the circumcircle of the fiber. Y is the basis weight (g / m ² ) of the nonwoven fabric. W ₀ is the optimum amount of the adhesive when aldehyde removal performance was examined using a nonwoven fabric having X of 18 μm and Y of 30 g / m ² . If it is less than 10 g / m ² , the adhesive strength will be insufficient, and if it exceeds 60 g / m ² , the aldehyde removal performance will be poor. The above formula is derived from the reference condition, and by using this formula, it is possible to easily determine the amount of the adhesive that can achieve both good adhesive properties and good adsorption performance even when the type of the nonwoven fabric changes.
[0031]
As the zeolite-based first adsorbent, one having an average particle size of 400 to 600 μm is used. If it is smaller than 400 μm, it is not suitable because it is difficult to adhere to the first sheet member when manufactured by the preferable manufacturing method of the present invention. It is considered that the smaller the particle size, the smaller the bonding area becomes. However, those having a diameter of more than 600 μm are not preferable because the surface area is small and the adsorption treatment efficiency is poor. A known granulation means may be used as needed to make the particle size range.
[0032]
Rather than using zeolite alone as the first adsorbent, zeolite is utilized as a water-absorbing supporting substance, and the zeolite chemically reacts with the component to be adsorbed in the presence of moisture to form the first adsorbent. A structure supporting an adsorptive compound capable of adsorbing an adsorption component is preferably used. Zeolite acts as a supporting substance and can absorb the moisture in the air by its water absorption, so even if it does not supplement the water serving as the reaction medium from the outside, the zeolite can be used in the presence of an adsorbent compound in the presence of water. Since it acts as a place for a chemical reaction with the component to be adsorbed, it is possible to achieve both improvement in adsorption performance and downsizing of the member for adsorption treatment. Zeolites can be classified into Na type and H type (proton type) depending on the ion type, but from the viewpoint of high reactivity with the component to be adsorbed, H type zeolites are preferred. The object of the present invention conforms to the object of the present invention in that the component to be adsorbed is a compound containing a carbonyl group such as formaldehyde, acetaldehyde, acrolein, and benzaldehyde contained in a malodorous or odorless toxic gas component.
[0033]
As the adsorptive compound, a compound that exhibits adsorption treatment ability in the presence of moisture is used. In particular, when a compound having active hydrogen that exhibits addition reactivity to the carbonyl group of the component to be adsorbed is used, these compounds can be adsorbed and removed by a chemical reaction. Representative examples of the adsorptive compound exhibiting addition reactivity with respect to the carbonyl group-containing compound include at least one selected from the group consisting of monohydric phenol, polyhydric phenol, and derivatives thereof.
[0034]
Specifically, monohydric phenols such as hydroxybenzoic acid, eugenol, 3,5-, 2,5-, 3,4-xylenol; dihydric phenols such as resorcin, bisphenol A and catechol; pyrogallol, purpurin, naringin, etc. And phenols such as tetravalent phenols such as rutin.
[0035]
Among these adsorptive compounds, resorcin, which belongs to polyhydric phenols, is very preferably used as an adsorptive compound because it exhibits extremely excellent reactivity with carbonyl group-containing compounds. When a weakly acidic substance such as oxalic acid or a weakly basic substance such as sodium carbonate is used together with resorcin, the effect of capturing aldehydes and the like is further enhanced, and a more excellent adsorption treatment effect is exhibited. This is thought to be because the weakly acidic substance or the weakly basic substance acts as a catalyst for the reaction between resorcinol and formaldehyde, and such an effect is obtained by using a monohydric phenol or polyhydric phenol other than resorcinol as the adsorbing compound. In this case, it is similarly effective.
[0036]
In the member for adsorption treatment produced by the production method of the present invention, the above-mentioned adsorbent compound is supported on zeolite and used as the first adsorbent, so that the carbonyl group-containing compound, which is a typical component to be adsorbed, A high level of adsorption treatment efficiency is obtained. Further, once the adsorption treatment is performed, the reactant is taken into the zeolite, so that the component to be adsorbed is not released again alone. Further, since the adsorption reaction proceeds in the presence of water, the adsorption performance is not hindered by moisture (moisture) in the air. In addition, as with the amine- or ammonia-based adsorbing compounds used in the prior art, the drug itself has problems such as odor problems, generation of highly corrosive acid ions, and sublimability. Also have no.
[0037]
The method of supporting the adsorptive compound on the zeolite is such that when the adsorptive compound is in a liquid state, the two are mixed and granulated so as to be within the above-mentioned predetermined range if necessary, and when the adsorptive compound is a solid, After dissolving in a suitable solvent such as water or methanol, the two may be mixed and heat-treated to remove the solvent. Since water serves as a reaction medium, water may remain in the granular material. Even if water does not remain, zeolite absorbs moisture in the air, so there is no need to replenish it.However, to exhibit a high level of adsorption activity from the beginning of the adsorption process, It is desirable that a proper amount of water be absorbed in the zeolite.
[0038]
The amount of the adsorptive compound may be appropriately selected in consideration of the activity of adsorption treatment, the amount of saturated carrier, the required adsorption performance, and the like, but is preferably 0.1 to 50% by weight based on the weight of zeolite. . If the amount is less than 0.1% by weight, the adsorption performance is not sufficiently exhibited, and even if it exceeds 50% by weight, no further improvement in the adsorption performance is observed. A more preferred amount of the adsorptive compound is 5 to 20% by weight based on the zeolite.
[0039]
FIG. 2 is an explanatory cross-sectional view of a representative example of the member for multilayer adsorption treatment 2 manufactured by the manufacturing method of the present invention. In the case of a multilayer structure, the second adsorbent 22 and the second sheet-like member 32 are laminated on the surface of the single-layer adsorption treatment member 1 described above to which the first adsorbent 21 is fixed. Configuration. That is, the first sheet-shaped member 31 and the second sheet-shaped member 32 constitute the adsorption processing member 2 having a configuration in which the first adsorbent 21 and the second adsorbent are sandwiched. Here, reference numeral 5 denotes an intermittent joining portion, which is a portion where the first sheet-like member 31 and the second sheet-like member are joined intermittently by welding or bonding, etc. It has a function of increasing the strength of the member 2.
[0040]
Since the first adsorbent utilizes a chemical reaction, it is preferable to use a physical adsorbent as the second adsorbent, for example, from the group consisting of activated carbon, silica gel, alumina, bentonite, diatomaceous earth and bauxite. One or more compounds of choice can be used. Activated carbon is preferred from the viewpoint of absorbing the offensive odor component.
[0041]
If any one of the first and second sheet members 31 and 32 is air-permeable, the suction treatment can be performed. However, it is most preferable that both sheet members are made of nonwoven fabric. If both the first sheet-like member 31 and the second sheet-like member 32 are non-woven fabrics using thermoplastic fibers, the intermittent joining part 5 is easily formed by joining using welding means such as heat sealing. it can.
[0042]
The means for fixing the second adsorbent 22 to the second sheet member 32 is not particularly limited. For example, an adhesive may be used in the same manner as when the first adsorbent 21 is fixed to the first sheet member 31 with the adhesive 41. Further, if the second sheet-like member 32 is formed of a thermoplastic material such as polyethylene non-woven fabric, the second adsorbent 22 is brought into contact with the second sheet-like member 32 while being welded by heating, so that both are fixed. Can be.
[0043]
Hereinafter, a production method of the present invention which can easily and efficiently produce the above-mentioned member for adsorption treatment will be described.
[0044]
First, the method for producing the member for single-layer adsorption treatment is as follows.
[0045]
A first zeolite-based adsorbent having an average particle size of 400 to 600 μm is sprayed on the base for spraying, and an adhesive is applied to the first sheet-like member. Is placed on the sprayed first adsorbent to bond the adhesive and the first adsorbent. Of course, it is necessary to adjust the amount of the adhesive and the amount of the zeolite so that the weight of the adhesive applied to the first sheet-like member is 10 to 60% by weight of the weight of the zeolite fixed on the first sheet-like member. is there.
[0046]
The substrate for spraying is not particularly limited as long as the first adsorbent can be sprayed thereon. In the case of continuous production, a movable conveyor belt can be used. In consideration of the inconvenience that the adhesive of the first sheet-shaped member falls, a plastic plate or the like subjected to a release treatment is preferable. In order to spray the adsorbent, a well-known spraying method such as a method of falling from a hopper or the like onto a spraying substrate is employed.
[0047]
The adhesive is applied to the first sheet-like member by the above-described method, and is placed on the first adsorbent being sprayed with the adhesive face down. The contact between the first adsorbent and the adhesive causes both to adhere. Therefore, if the dispersion pattern (pattern) of the adsorbent is matched with the adhesive application pattern, it is possible to easily separate the portion where the first adsorbent is present from the portion where the first adsorbent is not present.
[0048]
In the case of manufacturing a multilayer adsorption treatment member, the single-layer type is manufactured, and in the same manner as the single-layer type, a second sheet-like member to which the second adsorbent is fixed is manufactured. A method of superposing the two and bonding and welding can be adopted.
[0049]
Further, when a single-layer type is manufactured, a method of using a second sheet-like member to which a second adsorbent is fixed in advance as a base for spraying is more simple. That is, by placing the first sheet-like member coated with the adhesive on the second sheet-like member on which the second adsorbent is fixed in advance and the zeolite-based first adsorbent is sprayed, Since the first sheet-like member and the first adsorbent are fixed, a member for a multilayer adsorption treatment is manufactured. If heat and pressure are applied at 120 ° C. for about 10 seconds after the mounting, the first sheet member and the second sheet member are joined by the adhesive applied to the first sheet member. This bonding is preferably intermittent as shown in FIG. 2 because the adsorption performance is reduced when the bonding is performed over the entire surface. By employing this configuration, the first and second sheet-like members are hardly peeled off, and become a member for multi-layer adsorption treatment having high strength and excellent workability.
[0050]
The member for adsorption treatment of the present invention can be used as an adsorption treatment device or an air cleaning filter by being loaded into an appropriate casing, or as it is, or after being shaped. In addition to the use of the passage-type adsorption treatment on the premise that the gas to be treated is positively passed, for example, a method of performing adsorption treatment by adhering and carrying on a surface of a building material, wallpaper, or an ornament (contact-type adsorption treatment) May be used.
[0051]
【The invention's effect】
As a result of studying the relationship between the adsorption efficiency and the average particle size, the conditions of the particle size of the adsorbent that can be fixed to the sheet member with an appropriate amount of adhesive, and the like, the zeolite adsorbent having an average particle size of 400 to 600 μm was obtained. Was fixed to the sheet-like member with an adhesive in an amount of 10 to 60% by weight of the zeolite, thereby successfully providing a sheet-like adsorption treatment member having both good adsorption performance and adhesiveness. Also, by finding the relationship between the amount of the adhesive and the particle size and weight of the zeolite, a method for easily producing a member for adsorption treatment could be provided. Further, the multi-layer adsorption processing member can process various kinds of non-adsorption components with a simple structure.
[0052]
