Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a porous body used for a filter, a gas diffusion member, a heat radiating member, a water absorbing member, and the like.
[0002]
[Prior art]
The porous body can be applied to various uses such as a filter, a gas diffusion member, a heat radiating member, and a water absorbing member, and is provided in various devices. However, since the porous body has the properties of low strength and easy deformation, there is a problem that this handling is difficult.
[0003]
Therefore, in order to prevent the porous body from being damaged when the filter element made of the porous body is incorporated in the filter device, a technique for filling the end area of the filter element with a different substance and reinforcing it has been proposed. (For example, see Patent Document 1).
[0004]
In addition, in order to provide a fixing hole for attaching the metal foam to the apparatus, a technique for providing a portion for improving the strength by filling the pores of the porous body with a solid such as metal or plastic has been proposed. (For example, see Patent Document 2).

[Problems to be solved by the invention]
However, if an attempt is made to improve the strength by overlaying a resin or the like on the surface of the porous body, two types of materials, such as resin and metal, can be used simultaneously when trying to provide a fixing hole in the reinforcing portion. It will cut, it will be difficult to process, and shape provision will become difficult.
In addition, since the porous body is generally difficult to manufacture and expensive, it is desired to utilize the porous body without waste to fully exhibit its properties. On the other hand, the reinforcement in which the surface is coated with resin, metal or the like reduces the effective area of the porous body, resulting in an increase in cost.
[0007]
The present invention has been made in view of the above problems, and can improve the handleability of the porous body without sacrificing the effective area of the porous body. It aims at providing the porous body which can be formed reliably.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problems and achieve such an object, the present invention proposes the following means.
In the invention according to claim 1, a sheet-like porous body having a three-dimensional network structure and a reinforcing body extending in the surface direction from at least a part of the outer peripheral edge of the porous body are integrally formed via an adhesive. It is characterized by that.
[0009]
According to this invention, since the reinforcing body is disposed on the periphery of the porous body having low strength, it is possible to realize a porous body with good handleability. In addition, since the reinforcing body is disposed so as to protrude from the peripheral edge of the porous body, it becomes possible to perform machining, for example, only on the reinforcing body, and thereby, for example, a hole for fixing the device The shape can be easily given.
In addition, the part which arrange | positions a reinforcement body is not restricted to the perimeter of a porous body, and is not restricted to an outer edge part, It can arrange | position partially as needed. Moreover, the structure which connects a some porous body via an adhesive agent and a reinforcement body may be sufficient.
[0010]
In particular, in this invention, since the reinforcing body and the porous body are integrally formed through an adhesive, it acts on the heating temperature required for forming this composite porous body and the porous body having low strength. Therefore, the composite porous body can be easily and reliably formed.
[0011]
That is, for example, an insert part in which a porous body is used as an insert part and a resin part as a reinforcing body is injected so as to be continuous with the periphery of the porous body is used to dispose the resin part over the entire circumference of the porous body. Then, due to the difference in thermal expansion coefficient between the porous body and the resin part, the formed composite porous body may be deformed such as warping, or the porous body having low strength due to the injection pressure of the molten resin. May deform and further increase the deformation of the composite porous body.
However, in this invention, since the reinforcing body and the porous body are joined via the adhesive, the load acting on the porous body when forming the composite porous body can be minimized. .
[0012]
The invention according to claim 2 is the composite porous body according to claim 1, wherein the adhesive is made of an ultraviolet curable resin.
[0013]
According to the present invention, it is possible to further suppress the load acting on the porous body when forming the composite porous body.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the composite porous body 10 of the present invention has a sheet-like porous body 11 and a reinforcing body 12 extending in the surface direction of the porous body 11 formed integrally with an adhesive 13. A rectangular thin plate is formed.
[0015]
The porous body 11 is a rectangular thin plate having a three-dimensional network structure, and has air permeability and water absorption due to pores opened in the side portions in each direction, and is lightweight and has a large surface area. have. The porous body 11 may be made of metal or may be carbonaceous as containing crystalline graphite or non-crystalline amorphous carbon.
The reinforcing body 12 is in the form of a thin plate connected to the outer peripheral edge of the porous body 11 and is formed with almost the same thickness as the porous body 11 without a step. The reinforcing body 12 is not limited to any material, such as a synthetic resin or a metal, and may be appropriately selected according to the application in consideration of heat-resistant temperature and hardness.
The adhesive 13 is disposed between the outer surface of the porous body 11 and the inner surface of the reinforcing body 12 in a layered manner or interspersed, and joins the porous body 11 and the reinforcing body 12. This adhesive 13 may be organic or inorganic, such as glass, and may be any material that can bond them well in accordance with the material of the porous body 11 and the reinforcing body 12, taking into consideration the heat resistant temperature and hardness. It may be appropriately selected depending on the application.
The composite porous body 10 configured as described above forms a single thin plate member as a whole, and is attached to the apparatus by fixing or sandwiching the reinforcing body 12, and the filter, the water absorbing member, and the heat radiating body. Used for etc.
[0016]
Next, a porous body 11 made of metal, that is, a method for manufacturing the metal porous body will be described.
The porous body 11 can be manufactured by various methods. For example, the porous body 11 can be manufactured by firing a green sheet G obtained by thinly molding and drying a slurry S containing a metal powder. FIG. 2 shows a green sheet manufacturing apparatus 30 that thinly forms the slurry S by the doctor blade method.
[0017]
The slurry S is, for example, a mixture of metal powder such as SUS316L, an organic binder (methyl cellulose), and a solvent (water). If necessary, a foaming agent (hexane) or an antifoaming agent that sublimates or vaporizes by heat treatment. (Ethanol) etc. are added.
[0018]
In the green sheet manufacturing apparatus 30, first, the slurry S is supplied from the hopper 31 in which the slurry S is stored onto the carrier sheet 33 conveyed by the roller 32. The slurry S on the carrier sheet 33 is extended between the moving carrier sheet 33 and the doctor blade 34 and formed into a required thickness.
[0019]
The formed slurry S is further conveyed by the carrier sheet 33 and passes through the heating furnace 35. And it dries in the heating furnace 35, and the green sheet G of the state which the SUS316L powder was joined by the organic binder is formed.
In addition, when a foaming agent is contained in the slurry S, the slurry S in a state of being extended on the carrier sheet 33 is heat-treated in a high humidity atmosphere before drying to foam the foaming agent to obtain a foamed slurry. The green sheet G is formed by performing a drying process.
[0020]
The green sheet G is removed from the carrier sheet 33 and then degreased and fired in a vacuum furnace (not shown), thereby removing the organic binder and forming the porous body 11 in which the metal powders are sintered.
[0021]
The porous body 11 formed in this manner is disposed inside the reinforcing body 12, and an adhesive 13 is disposed between the porous body 11 and the reinforcing body 12, and the adhesive 13 is cured. The composite porous body 10 shown in FIG. 1 is formed.
Here, when the adhesive 13 is cured, by pressing or heating and pressing these surfaces, the composite porous body 10 can be formed with high accuracy, and the porous body 11 and the reinforcement are strengthened. The bonding strength with the body 12 can be improved.
Further, when the adhesive 13 is disposed between the porous body 11 and the reinforcing body 12, the adhesive 13 is impregnated and cured to a depth of about 5 μm to 1000 μm in the pores opened in the side portion of the porous body 11. By doing so, it will be firmly joined (anchor effect).
Further, when an ultraviolet curable resin is used as the adhesive 13, it is sufficient to irradiate ultraviolet rays when the adhesive 13 is cured, and it is not necessary to heat them. Therefore, when the composite porous body 10 is formed, the load acting on the low-strength porous body 11 can be minimized, so that the composite porous body 10 can be satisfactorily produced without causing deformation such as warpage. Can be formed. In addition, when the porous body 11 and the reinforcing body 12 are altered or deformed by ultraviolet rays, it is preferable to mask the porous body 11 and the reinforcing body 12 in advance when the ultraviolet rays are irradiated. In addition, since the curing rate of the ultraviolet curable resin can be controlled relatively easily, the above-described impregnation depth of the adhesive 13 from the side portion of the porous body 11 can be controlled with high accuracy.
[0022]
If the porous body 11 has a pore diameter or porosity that is too small, the adhesive 13 cannot enter the pores, so that the anchor effect described above becomes insufficient, and the bonding strength with the adhesive 13 cannot be sufficiently obtained. There is a risk of peeling at the part. On the other hand, if the pore diameter or the porosity is too large, the strength is insufficient, the compression during the curing of the adhesive 13 cannot be endured, and there is a risk of deformation. Therefore, it is more preferable that the pore diameter is about 10 μm to 2 mm and the porosity is about 40 to 98%.
[0023]
As described above, according to the composite porous body according to the present embodiment, since the reinforcing body 12 is disposed on the outer peripheral edge of the low-strength porous body 11, it is possible to realize the porous body 11 with good handleability. Can do. Further, since the reinforcing body 12 is disposed so as to protrude from the peripheral edge of the porous body 11, for example, machining can be performed only for the reinforcing body 12, thereby fixing the device. A shape such as a hole can be easily provided.
[0024]
In particular, in the present embodiment, since the reinforcing body 12 and the porous body 11 are integrally formed via the adhesive 13, the heating temperature and strength required for forming the composite porous body 10 are increased. The load acting on the low porous body 11 can be suppressed to the minimum, and the composite porous body 10 can be formed easily and reliably.
[0025]
That is, for example, the resin part is formed over the entire circumference of the porous body 11 by insert molding in which the porous body 11 is used as an insert part and the resin part as the reinforcing body 12 is injected so as to be continuous with the periphery of the porous body 11. If it is intended to be disposed, deformation such as warpage occurs in the formed composite porous body 10 due to the difference in thermal expansion coefficient between the porous body 11 and the resin portion, or due to the injection pressure of the molten resin. There is a possibility that the porous body 11 having low strength is deformed and the deformation of the composite porous body 10 is further increased.
However, in the present embodiment, since the reinforcing body 12 and the porous body 11 are joined via the adhesive 13, it acts on the porous body 10 when forming the composite porous body 10. The load can be minimized.
[0026]
In this embodiment, the reinforcing body 12 is flat as shown in FIG. 1, but a hole for a screw insertion hole, a groove shape for fitting to a device, a rib shape for improving strength, a boss, etc. It may be provided.
