Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing an activated carbon porous body structure. More specifically, the present invention relates to a method for producing an activated carbon porous material structure suitable for an electrode of an electric double layer capacitor, ozone decomposition, a deodorizing filter and the like.

[0002]

BACKGROUND OF THE INVENTION Structures containing activated carbon as a main component have been used for applications such as electrodes of electric double layer capacitors, ozone decomposition and deodorizing filters. A method for producing such an activated carbon structure is disclosed in, for example, JP-A-58-84.
The method disclosed in Japanese Patent No. 180 is known.
In this method, a composition is prepared by blending a small amount of a binder resin with an excess of activated carbon powder or carbon powder, and the composition is vigorously stirred under pressure with a device having a large horsepower such as an extruder. It is a method of pouring into a metal mold and then heating to solidify.

However, according to such a method, the viscosity of the resin composition is high and it is difficult to add a large amount of a curing agent to the resin composition. As a result, the curing speed of the resin composition becomes slow, and the curing reaction hardly progresses at a temperature of 100 ° C. or lower. Therefore, here, a method is adopted in which the resin composition injected into the metal mold is treated and cured at a high temperature without removing the mold. As a result,
There are problems that the process becomes complicated and many molds are required.

Under these circumstances, a method of filling a thermosetting resin into a metallic mold and carbonizing and activating the resin filled in the metallic mold to produce an activated carbon structure has been tried. However, this method has a problem in that the thermosetting resin adheres to the mold, causing a defect when the obtained activated carbon structure is taken out.

[0005]

An object of the present invention is to provide a method for easily producing an activated carbon porous body structure by molding a structure of a raw material resin composition of activated carbon by a simple method, followed by carbonization and activation. It is an object.

[0006]

1 to 100 parts by weight of a compound (b) which is lipophilic and has a boiling point of 100 ° C. or higher at room temperature, and hydrophilic and has a low residual carbon rate of 10
A resin composition comprising 1 to 100 parts by weight of a liquid compound (c) having a boiling point of 0 ° C. or higher is poured into a flexible mold having a plurality of protrusions formed of a soft resin to obtain the resin. After the composition is cured to have at least self-supporting property to form a resin structure, the flexible mold is released from the resin structure, and then the resin structure is carbonized at a temperature of 500 ° C. or higher. , Is characterized by activating.

In the method of the present invention, since a flexible frame having a plurality of protrusions formed of a soft resin is used, a cured product (resin structure) of a resin composition containing a resol-type phenol resin is used. Can be easily released from the mold,
Furthermore, during release, the holes formed in the resin structure due to the protrusions are less likely to be deformed or chipped.

DETAILED DESCRIPTION OF THE INVENTION Next, the method for producing the activated carbon porous material structure of the present invention will be specifically described. FIG. 1 is a diagram conceptually showing an example of an apparatus for continuously producing an activated carbon porous body structure.

2 and 4 are perspective views schematically showing an example of the flexible formwork used in the present invention. 3 and 5 are perspective views schematically showing an example of a resin structure manufactured by using the flexible mold.

FIG. 6 is a plan view showing another embodiment of the flexible mold, and FIG. 7 is a sectional view taken along the line AA of this flexible mold. Resol type phenolic resin used in the present invention (a)
Is a resin obtained by condensing a phenol and an aldehyde in an equivalent amount or an excess amount with respect to the phenol in the presence of a basic catalyst. Phenols used here are phenol, m-cresol,
Examples include p-alkylphenol and resorcin, and examples of aldehydes include formaldehyde and furfural. Aldehydes are 1 per mol of phenols
Used in an amount of ~ 3 mol. The basic catalyst used in this reaction is, for example, NaOH, KOH, Ca (OH) ₂ , B
a (OH) ₂ , NH ₂ (CH ₂ CH ₃ ) and the like. Phenols and aldehydes in the presence of the above catalyst, 80 to 10
Heat to 0 ° C to condense, then solid content 60-80%
The resol-type phenol resin (a) used in the present invention can be obtained by distilling off the water under reduced pressure until the above temperature reaches. Resol type phenol resin obtained in this way
The viscosity of (a) is usually 1000 to 20000c at room temperature.
A liquid in the ps range. This liquid is generally a mixture of methylolphenols containing monomethylolphenol, dimethylolphenol and trimethylolphenol as a main component.

A lipophilic compound (b) and a hydrophilic compound (c) are blended with this resol type phenol resin. The lipophilic compound (b) is a compound having a boiling point of 100 ° C. or higher at normal pressure, preferably 100 to 400 ° C., and is a lipophilic compound that is liquid at room temperature. This lipophilic compound (b)
As, for example, linear aliphatic hydrocarbons such as octane, nonane, decane, undecane, dodecane, kerosene, mineral oil, liquid paraffin, or branched aliphatic hydrocarbons, and toluene, xylene, etc. Aromatic hydrocarbons and the like can be mentioned.

Of these, liquid paraffin is preferable because it has a viscosity similar to that of the resol-type phenol resin (a) and a stable oil-in-water dispersion system can be prepared when mixed.

The lipophilic compound (b) is added in an amount in the range of 1 to 100 parts by weight, preferably 10 to 60 parts by weight, based on 100 parts by weight of the resol type phenol resin (a).

If the amount of the lipophilic compound (b) is too small, it becomes difficult to form an effective porous structure in the activated carbon porous body structure, and the resulting activated carbon polymorphic structure has adsorption performance and liquid impregnation property. Will be inferior in characteristics. In addition, explosion occurs during carbonization and activation, which makes it difficult to manufacture the activated carbon porous body structure. On the other hand, if it exceeds the above amount, resol type phenol resin
The curing property of (a) becomes inferior. In addition, since the shrinkage of the cured product during carbonization is large, cracking is likely to occur.

Further, the hydrophilic compound (c) has a boiling point of 100.
A compound having a temperature of ℃ or higher, preferably 200 to 400 ℃,
It is a liquid compound (c) at room temperature. Moreover, the hydrophilic compound (c) needs to have a low residual carbon rate, and for example, a compound having a residual carbon rate of 10% by weight or less when heated at 500 ° C. for 5 hours is used. Such a hydrophilic compound (c)
Examples thereof include oxyalkylene compounds having a degree of polymerization of 2 or more, and specific examples thereof include diethylene glycol, triethylene glycol and a molecular weight of 1000.
Less than polyethylene glycol, dipropylene glycol, less than 1000 molecular weight polypropylene glycol,
Alternatively, glycerin can be mentioned.

Of these, polyethylene glycol having a molecular weight of 400 to 600 or dipropylene glycol is preferable because it is relatively close to the viscosity of the resol type phenol resin (a) and has a suitable compatibility.

The hydrophilic compound (c) is added in an amount within the range of 1 to 100 parts by weight, preferably 10 to 60 parts by weight, based on 100 parts by weight of the resol type phenol resin (a). When the amount of the hydrophilic compound (c) is too small, the dispersion stability of the lipophilic compound (b) is poor, and phase separation easily occurs,
On the other hand, when the amount exceeds the above amount, the curing characteristics of the resol-type phenol resin (a) are impaired, and the hydrophilic compound and the resol-type phenol resin (a) are likely to undergo phase separation.

In the present invention, the lipophilic compound (b) and the hydrophilic compound (c) have a weight ratio (value of (b) / (c)) of 0.3 to
It is preferable to use it in a ratio within the range of 3, and if it deviates significantly from this range, the mixture (resin composition) comprising the above-mentioned components (a), (b) and (c) is likely to undergo phase separation.

Further, a resol type phenol resin (a),
The lipophilic compound (b) and the hydrophilic compound (c) are preferably used in a weight ratio ((a) / [(b) + (c)]) of 0.8 to 5.

The composition comprising the resol type phenolic resin (a), the lipophilic compound (b) and the hydrophilic compound (c) usually contains a curing agent for curing the resol type phenolic resin (a). Compound.

As the curing agent for the resol type phenol resin (a), various well-known strongly acidic compounds can be used. Examples of such strong acid compounds include hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, pyrophosphoric acid, inorganic acids such as polyphosphoric acid, phenolsulfonic acid, benzenesulfonic acid, toluenesulfonic acid, metacresolsulfonic acid and other organic acids, Alternatively, a mixture of these may be mentioned.

The amount of the curing agent used is usually in the range of 1 to 30 parts by weight with respect to 100 parts by weight of the resol type phenol resin. The resin composition used in the present invention may further contain a surfactant, another filler, and the like.

The resin used in the present invention is prepared by mixing the components forming the resin composition continuously, batchwise or simultaneously with a mixer having a stirring blade rotating at a high speed. The composition can be manufactured.

The resin composition thus prepared is poured into a mold. The formwork used in the present invention is a flexible formwork, rather than the metal formwork used conventionally. This flexible mold has a plurality of protrusions formed of a soft resin. Examples of the soft resin forming the protrusions include ethylene / propylene copolymer, polyisoprene rubber, butadiene / styrene copolymer, polybutadiene rubber, polychloroprene rubber, isoprene / isobutylene copolymer, butadiene / acrylonitrile copolymer. Examples thereof include polymers, alkyl acrylate copolymers, urethane rubbers, silicone rubbers, fluororubbers, polysulfide rubbers, chlorosulfonated polyethylenes and natural rubbers. Among these, silicone rubber is preferable.

The mold used in the present invention has a plurality of protrusions 11 as shown in FIGS. 2 and 4, for example. The shape of the protrusion may be a columnar protrusion in which the bottom diameter D ₁ and the top diameter D ₂ of the protrusion are equal as shown in FIG.
As shown in FIG. 4, the protrusion may have a truncated cone shape or a cone shape in which the bottom diameter D ₁ is wider than the top portion D ₂ . In the case of a cylindrical protrusion, the bottom diameter D ₁ and the top portion D ₂ are
Both are usually 0.2 to 30 mm, preferably 1 to 10 mm. Further, in the case of a truncated cone-shaped or cone-shaped protrusion, the bottom diameter D ₁ is usually 0.2 to 30 mm, the top diameter D ₂ is usually 0 to 29 mm, and the bottom diameter D ₁ is always the top diameter D _2. Greater than. In the present invention, it is preferable to use a flexible mold having a truncated cone-shaped or a cone-shaped protrusion. It is easy to release the mold from the structure of the cured product of such a resol type phenol resin, and the peripheral edge of the hole formed in the structure by the projection is less likely to be chipped during the release, and the activated carbon has few defects. A porous structure can be obtained.

The height H of the protrusion can be set appropriately, but is usually 0.2 to 30 mm. The distance between one protrusion and the other protrusion is not particularly limited, but is usually 0.5 to 10 mm.

FIG. 6 shows a front view of a flexible mold having such a conical projection, and FIG. 7 shows a sectional view taken along line AA. In FIGS. 6 and 7, the conical protrusion is indicated by 11. The conical projection 11 is planted on a flexible base material 12. Weirs 13 are provided at both edges of the base material 12 so that the resol-type phenol resin does not flow out from the edges. 6 and 7 show a mode in which the weir 13 is provided at the edge portion in the length direction, the weir can also be provided at the edge portion in the width direction. In particular, when the activated carbon porous body structure is manufactured discontinuously, it is preferable to use a flexible mold having a weir provided in both the length direction and the width direction. In such a flexible mold, it is necessary that the base material and the weir also have flexibility, and normally, the base material and the weir are also made of a soft resin forming the protrusions. Has been formed.

In the method for producing an activated carbon porous body structure of the present invention, first, the above-mentioned flexible mold is provided with the component (a) and the component (b).
A structure is manufactured by injecting a resin composition containing the component and the component (c) and curing the resin composition until at least self-supporting property is exhibited. Then, after releasing the flexible form from the structure having self-supporting property, the structure was
Carbonize and activate at a temperature of 00 ° C or higher.

Particularly, it is preferable to arrange the flexible molds continuously to continuously manufacture the activated carbon porous body structure. The continuous method for producing the activated carbon porous body structure will be described below.

FIG. 1 schematically shows an apparatus used in this continuous manufacturing method. The flexible formwork 1 is arranged on an endless belt 5 such as a belt conveyor. In the flexible formwork 1 arranged on the endless belt 5,
The resol type phenolic resin composition 2 containing the component (a), the component (b) and the component (c) is injected. At this stage, the resol type phenol resin composition 2 has fluidity, and the composition does not exhibit self-supporting property.

The resol type phenolic resin composition thus injected into the flexible mold is then sent to the heating zone 3. The heating zone 3 is provided with a heating means such as a far infrared heater, and the resol type phenol resin composition is usually heated to a temperature of 100 ° C. or lower by this heating means.
It is preferably heated to a temperature within the range of 50 to 90 ° C.
By heating as described above, the curing reaction of the resol-type phenol resin composition proceeds. The curing reaction is performed at least until the resol-type phenol resin composition exhibits self-supporting properties. For example, at the heating temperature as described above, the time required for the self-supporting property to develop is usually 3 to 120 minutes, preferably 10 to 30 minutes.

The resol-type phenol resin composition cured to the extent that self-supporting property is developed as described above is then sent to the cooling zone 4. A cooling medium such as air circulates in this cooling zone, and the resol type phenol resin composition heated in the heating zone 3 is cooled here.

The resol type phenolic resin composition 2 thus cooled together with the flexible mold 1 has an endless belt 5.
To move to the rotating end of the endless belt 5. At this rotating end, the flexible frame 1 rotates downward along the rotation axis together with the endless belt 5, but the resol-type phenol resin composition 2 has already hardened to have self-supporting property. The flexible mold 1 is released from the resol-type phenolic resin composition 2. At this time, the protrusion of the flexible frame formed of the soft resin is released from the cured resole-type phenol resin composition 2 while being deformed in response to the applied stress. Since the projections are released from the mold while deforming as described above, the cured resol-type phenolic resin composition 2, that is, the peripheral edge portion of the holes of the resin structure is not chipped during the mold release, and is flexible. Since the frame is deformed and gradually released from the resin structure, the adhesive force of the resin structure with respect to the flexible mold is reduced, so that the mold can be easily released.

The resin structure is provided with holes having a shape corresponding to the shape of the projection of the mold used. For example, when a mold having a protrusion as shown in FIG. 2 is used, a resin structure having holes as shown in FIG. 3 can be obtained, and a mold having a protrusion as shown in FIG. When is used, a resin structure having holes as shown in FIG. 5 can be obtained.

Further, by changing the size of the protrusion, it is possible to obtain a resin structure having a hole of a desired size, that is, if there is a large protrusion on the surface of the mold,
A resin structure having a large hole can be obtained, and if the surface has small protrusions, a resin structure having a large number of small holes can be obtained.

By providing holes in the resin structure, the resol-type phenol resin composition can be efficiently cured and the resin structure can be efficiently carbonized and activated, and the resulting activated carbon porous structure can be obtained. The adsorption performance of the body is also improved.

The resin structure thus released is further advanced by another belt conveyor and sent to the table 8. This table 8 is equipped with a cutter 9,
The cutter 9 cuts the resin structure into a desired shape.

The cut resin structure (cut active carbon porous material precursor) 7 is then heated and carbonized in a non-oxidizing atmosphere. Upon carbonization, the resin structure may be used as it is, or the resin structure may be cut and carbonized, for example, as a plate-shaped body.

Here, the non-oxidizing atmosphere is, for example, Ar.
Gas, He gas, N ₂ gas, halogen gas, ammonia gas, CO gas, hydrogen gas, or mixed gas thereof, water gas and the like. The temperature for carbonization is 500 ° C
Above, it is usually heated to a temperature in the range of 500 to 1200 ° C, preferably 600 to 900 ° C.

The carbon porous body obtained as described above is
Further, activation treatment is applied to activate. The activation step may be continuous with the carbonization step or may be a step separate from the carbonization step. Activation of the carbon porous body is performed by heating the carbon porous body in an atmosphere of an oxidizing gas or a mixed gas of an oxidizing gas and an inert gas.

The heating temperature is 600 ° C to 1200 ° C, preferably 750 to 1000 ° C. As oxidizing gas,
A known oxidizing gas (eg, steam, carbon dioxide, oxygen, air, etc.) is used. These oxidizing gases are usually
It is used as a mixture with an inert gas such as nitrogen gas for forming an arbitrary oxidizing atmosphere.

The activated carbon porous material structure obtained by the method of the present invention can be used for applications such as electrodes of electric double layer capacitors, ozone decomposition and deodorizing filters, in which activated carbon has been used conventionally.

[0043]

According to the production method of the present invention, a resol type phenol resin / lipophilic compound /
A resin composition made of a hydrophilic compound is used, and a thin resin sheet can be formed by utilizing the excellent fluidity of the resin composition. For example, a thin activated carbon porous body having a thickness of about 1 mm can be easily manufactured. Further, since the curing agent can be easily mixed, the molding speed can be increased as compared with the conventional method. Moreover, in the method of the present invention, since the flexible mold having the projections formed of the soft resin is used as the mold, the flexible mold can be easily separated from the cured body of the resin composition. Can be molded. Furthermore, since the holes formed in the resin cured body by the protrusions are less likely to be lost at the time of releasing, it is possible to manufacture an activated carbon porous body structure having few defects.
