Description

The present invention relates to a section penetration processing structure formed in a partition portion of a building or the like, a partition penetration processing material for forming a partition penetration treatment structure, and a method for constructing a partition penetration treatment structure.

In buildings such as apartment houses, office buildings, and schools, partition penetrations such as walls may be provided with partition penetrations for passing long inserts such as cables and pipes. The section penetration portion is required to have a structure (fireproof structure) with fire prevention measures in order to prevent the spread of fire to the other section when a fire breaks out in any section. The partition portion is generally a hollow wall composed of two wall portions and having a hollow portion between the wall portions.

As a method of making the partition penetrating portion a fireproof structure, for example, a method of filling a gap between a long insertion body and a through hole with an amorphous filler such as a fireproof putty is known. When an amorphous filler is used, a cylindrical member made of a refractory material may be disposed together between the inside of the through hole of each wall portion and the insertion body (for example, Patent Document 1, Patent Document 1, 2).

Japanese Patent No. 6150933 Japanese Patent No. 6348320

However, when an amorphous filler is used for the fire protection treatment of the section penetrating portion, there are variations depending on the operator, and sufficient fire resistance may not be obtained. In addition, when installing refractory materials and their accessories inside the frame, it is not clear how much (amount, thickness, length, etc.) they are installed, or it cannot be determined whether they are installed as specified. I have something to do. Therefore, in order to confirm whether or not the refractory material is installed as specified, it is necessary to destroy the section penetration processing structure and confirm the internal structure.

In addition, in order to reduce variations due to workers, there was a kit in which members of a predetermined amount and size were integrated, but the number of members tends to be large, and it is easy for parts to be lost or forgotten to be installed. In addition, there is a problem that a lot of dust is generated because each kit is packed.

In addition, in the compartment penetration structure in which long inserts such as cables and pipes are inserted, if the insert is moved after the compartment penetration processing structure is applied, the refractory material installed inside. Etc. may deviate from the proper position where they were installed. In addition, due to an external force such as an earthquake, the refractory material may deviate from the appropriate position where it was installed. In addition, if the refractory material does not expand uniformly but expands unevenly, it may deviate from the appropriate position where it was installed or may fall off. As described above, if the refractory material or the like is displaced from the appropriate position where it is installed, it becomes difficult to exhibit the fire resistance performance desired as the fire resistance structure of the section penetrating portion.

Therefore, it is an object of the present invention to provide a compartment penetration treatment structure, a construction method of a compartment penetration treatment structure, and a compartment penetration treatment material capable of reducing the variation in fire resistance performance and improving the fire resistance performance.

Hereinafter, the present invention will be described in more detail using embodiments.

[First Embodiment]
As shown in FIG. 1, the compartment penetration processing structure according to the first embodiment of the present invention is formed in the partition portion 11 of the building, and the compartment penetration portion 15 through which the long insertion body 21 is inserted is inserted. It is a compartment penetration processing structure with a fireproof structure.

The partition portion 11 in the compartment penetration processing structure of the present invention is a member that partitions between compartments (first compartment A and second compartment B) on the wall surface of the building, and is from one outer surface 11A side of the partition portion 11. It has a compartment penetrating portion 15 penetrating the other outer surface 11B side. The partition portion 11 shown in FIG. 1 is a hollow wall, and is composed of two wall materials (partition materials) 12A and 12B arranged via an interval (hollow portion 13). Therefore, the partition penetrating portion 15 is composed of a through hole 13A formed in one wall material 12A, a through hole 13B formed in the other wall material 12B, and a hollow portion 13 between them. The outer surface of one wall material 12A constitutes the outer surface 11A of the partition portion 11, and the outer surface of the other wall material 12B constitutes the outer surface 11B of the partition portion 11. The through holes 13A and 13B may have, for example, a circular shape, an elliptical shape, or a shape similar thereto. The through holes 13A and 13B on the outer surfaces 11A and 11B respectively constitute openings 13C and 13D of the partition penetrating portion 15 provided in the partition portion 11.

In addition, in this specification, a member (in this embodiment, a sheet-like member 3, a fixing member for fixing these, etc.) which is constructed in a section penetration portion 15 and is constructed for forming a section penetration processing structure 10 is put together. It is sometimes called a compartment penetration treatment material.
Further, in the following, the configuration of the partition penetration processing structure on one opening 13C side of the partition portion 11 will be described, but in the present embodiment, the configuration of the partition penetration processing structure on the other opening 13D side is also the same. Is omitted.

The partition penetration processing structure 10 according to the first embodiment includes a sheet-shaped member 3 and a cover member 5 as a partition penetration processing material, and the sheet-shaped member 3 has at least a refractory material as described later.

[Sheet-like member]
As shown in FIG. 1, the sheet-shaped member 3 has a slit 32 for inserting the insertion body 21 into the inside, and at least one of the slits 32 extends to the outer edge of the sheet-shaped member 3. The slit 32 is formed by a notch. The sheet-shaped member 3 can insert the insertion body 21 into the inside of the sheet-shaped member 3 through the slit 32 extending to the outer edge. The slit 32 may have a hole for inserting the insertion body 21 into the inside, and a slit 32 extending from the hole to the outer edge of the sheet-shaped member 3.

As shown in FIG. 2, the sheet-like member 3 into which the insertion body 21 is inserted by the slit 32 is placed on the outer surface 11A from the outside of the partition portion 11 so as to cover the gap 13E between the opening 13C and the insertion body 21. Arranged so that the gap 13E between the opening 13C and the insert 21 is closed by the sheet-like member 3. It is preferable that the sheet-shaped member 3 is arranged so as to be in contact with both the outer surface 11A of the partition portion 11 and the outer periphery of the insertion body 21. By installing the sheet-shaped member 3 so as to be in contact with the insertion body 21 and the partition portion 11, the opening 13C of the partition portion 11 can be closed, and the fire resistance performance can be improved and maintained.

In the present embodiment, as shown in FIGS. 3A to 3E, the sheet-shaped member 3 is laminated with at least three layers of a base material and a refractory material layer having thermal expansion alternately. Specifically, as shown in FIG. 3A, the sheet-shaped member 3 may have three layers of the base materials 30A and 30B and the refractory material layer 31A alternately laminated, and is shown in FIG. 3B. As described above, the base material 30A and the refractory material layers 31A and 31B may be alternately laminated in three layers. The sheet-shaped member 3 is not limited to the three-layer structure, and as shown in FIG. 3C, the base materials 30A and 30B and the refractory material layers 31A and 31B may be alternately laminated in four layers.

Further, as long as the sheet-shaped member 3 has a base material / refractory material layer / base material or a refractory material layer / base material / refractory material layer in this order, the base material and the refractory material layer are alternately provided one by one. It is not necessary to be used, and layers of the same type such as a base material / base material and a refractory material layer / refractory material layer may be continuously laminated. For example, as shown in FIG. 3D, the base materials 30A and 30B may be continuously laminated, and the base materials 30B and 30C and the refractory material layer 31A may be alternately laminated. Further, as shown in FIG. 3E, the sheet-shaped member 3 has no limitation on the number of layers, and the plurality of base materials 30A, ... 30Y, 30Z and the plurality of refractory material layers 31A, ... 31Y, 31Z may be alternately laminated in multiple layers.

In the present invention, the base material and the refractory material layer having thermal expansion are alternately laminated at least three layers, so that the refractory material layer is appropriately supported by the base material when the sheet-like member 3 is heated. The heat can be evenly distributed, the refractory material layer can be expanded substantially uniformly, and the refractory resistance can be improved. Further, since the refractory material layer of the sheet-shaped member 3 expands substantially uniformly, the refractory material layer is maintained at an appropriate position in which it is installed and does not shift, so that the refractory material can be stably exhibited. Further, by using the sheet-shaped member 3, the refractory structure is formed without arranging the filler such as fire-resistant putty and rock wool inside the partition penetrating portion 15, so that variations may occur depending on the operator. do not have.
Further, when a plurality of refractory material layers are laminated on the sheet-shaped member 3, the refractory material layer on the expanded partition portion 11 side is embedded in the gap 13E, and when the sheet-shaped member 3 expands, the refractory material layer is formed from the partition portion 11. It prevents them from separating and makes the above-mentioned deviation less likely to occur. On the other hand, the refractory material layer located at a position away from the partition portion 11 expands evenly as described above, and the expansion residue can appropriately prevent the spread of fire.

When the sheet-shaped member 3 has a plurality of refractory layers, the expansion ratio of the refractory layer farthest from the outer surface 11A of the partition portion 11 is higher than the expansion ratio of the refractory layer closest to the outer surface 11A of the partition portion 11. Is preferable. That is, in the sheet-shaped member 3 in FIGS. 3B and 3C, it is preferable that the expansion ratio of the refractory material layer 31B is higher than the expansion ratio of the refractory material layer 31A. The expansion ratio of the refractory material layer can be controlled, for example, by selecting the amount and type of the heat-expandable member.
As described above, when the expansion ratio of the refractory material layer on the partition portion 11 side is low, the strength of the expansion residue is maintained high, and the sheet-like member 3 is appropriately supported by the refractory material layer embedded in the gap 13E, and is displaced. Is even less likely to occur. Further, the refractory material layer at a position away from the partition portion 11 is sufficiently expanded by heating, and it becomes easy to exhibit higher fire resistance performance.

When the number of refractory material layers is three or more, the refractory material separated from the outer surface 11A of the partition portion 11 is to be expanded more uniformly and better than the outer surface 11A of the partition portion 11. It is preferable that the layer has a higher expansion ratio.
Further, in the above-mentioned multilayer structure, the above-mentioned layers adjacent to each other may be adhered by a known adhesive, and therefore, in each of the above-mentioned laminated structures, an adhesive layer may be provided between the above-mentioned layers. ..
In the multi-layer structure, the sheet-like member 3 may have the same layer structure as a whole, but may have a partially different structure. For example, the layer structure of the base material and the refractory material layer may be partially changed.

The refractory material layer used for the sheet-shaped member 3 is a heat-expandable member that expands by heating. The heat-expandable member expands in the event of a fire to prevent the spread of fire. The heat-expandable member is preferably formed of a heat-expandable resin composition as described later.
The thickness of each refractory material layer is not particularly limited, but is, for example, 0.1 to 15 mm, preferably 0.5 to 8 mm. When the refractory material layer has a thickness equal to or less than these upper limit values, flexibility is imparted to the sheet-shaped member 3. In addition, having a thickness equal to or greater than the lower limit makes it easier to secure fire resistance.

The base material used for the sheet-shaped member 3 supports the refractory material layer and evenly transfers heat to the refractory material layer. Examples of the base material include metal foils such as aluminum foils and copper foils, metal cloths such as aluminum glass cloths, metal leaf composites such as composites of metal foils and glass cloths, paper, cloth, resin films and the like. .. Among these, from the viewpoint of fire resistance, it is preferable that the material is composed of a non-combustible material, and specific examples thereof include a metal foil and a metal foil composite. Non-combustible materials are defined in the Building Standards Act and the Building Standards Act Enforcement Ordinance.
The base material is preferably arranged in the outermost layer at a position opposite to the partition portion 11. Since the base material is arranged on the outermost layer of the sheet-like member 3, the refractory material layer arranged inside can be well supported and heat can be evenly transferred to the refractory material layer. The layer can be better and more uniformly expanded.
The thickness of each substrate is not particularly limited, but is, for example, 0.01 to 1 mm, preferably 0.05 to 0.5 mm. When the non-combustible material layer has a thickness equal to or less than these upper limit values, flexibility is imparted to the sheet-shaped member 3. In addition, having a thickness equal to or greater than the lower limit makes it easier to secure fire resistance.

As shown in FIG. 4A, the sheet-shaped member 3 has a structure in which the refractory material layer 31A having adhesiveness is formed on the outermost surface, or has an adhesive layer 33 as shown in FIG. 4B. It is preferable that the refractory material layer 31A is configured on the outermost surface. With the above configuration, the sheet-shaped member 3 is arranged in contact with the outer surface 11A of the partition portion 11 by the refractory material layer or the adhesive layer having adhesiveness arranged inside (that is, the partition portion 11 side). You may. With the above configuration, the sheet-shaped member 3 can be fixed to the partition portion 11 without using a fixing member as a member separate from the sheet-shaped member 3. Further, by making the refractory material layer itself adhesive, it is not necessary to provide the adhesive layer, so that the configuration of the sheet-like member 3 can be further simplified. When the outermost surface of the sheet-shaped member 3 is provided with a refractory material layer or an adhesive layer having adhesiveness, a release sheet may be attached to the outermost surface thereof. The release sheet may be peeled off from the outermost surface during use.
The refractory material layer can be imparted with adhesiveness by being formed of butyl rubber or the like.
The pressure-sensitive adhesive layer may be formed of a pressure-sensitive adhesive, and as the pressure-sensitive adhesive, for example, an acrylic pressure-sensitive adhesive, a urethane-based pressure-sensitive adhesive, a rubber-based pressure-sensitive adhesive, a silicone resin-based pressure-sensitive adhesive, or the like can be used. The pressure-sensitive adhesive layer may be nonflammable, semi-nonflammable, or flame-retardant, and a flame-retardant or the like may be added to the pressure-sensitive adhesive to be used. The thickness of the pressure-sensitive adhesive layer is, for example, 5 to 400 μm, preferably 10 to 150 μm.
Further, the sheet-shaped member 3 can be fixed to the outer surface 11A of the partition portion 11 by a fixing member which is a member different from the sheet-shaped member 3 such as a tacker and a screw. These fixing members may be installed on the outside of the sheet-shaped member 3 (that is, on the side opposite to the partition portion 11).
Of course, the sheet-like member 3 may be fixed to the partition portion 11 by a combination of these two or more.

The thickness of the sheet-shaped member 3 is not particularly limited, but is, for example, 0.1 to 20 mm, preferably 0.5 to 10 mm.

[Cover member]
The cover member 5 is a member that is provided so as to be connected to the sheet-shaped member 3 and covers the sheet-shaped member 3 provided in the partition portion 11. As shown in FIG. 1, for example, four cover members 5 are used so as to be connected to the four sides of the sheet-shaped member 3, and four extending portions extending outward from the sheet-shaped member 3 are used. , As shown in FIG. 2, covers the sheet-like member 3 provided in the partition portion 11. As a means provided so that the cover member 5 is connected to at least a part of the sheet-shaped member 3, for example, an adhesive, an adhesive and an adhesive tape, and a known fixing means such as a fixing member such as a tacker or a screw are used. Means to be fixed can be mentioned. Here, the adhesive, the pressure-sensitive adhesive and the pressure-sensitive adhesive tape are preferably any of a non-combustible material, a semi-non-combustible material or a flame-retardant material, and a flame-retardant agent or the like may be blended with the adhesive, the pressure-sensitive adhesive or the like.
Since the cover member 5 is in the shape of a sheet and can be deformed, the sheet-like member 3 can be easily covered.

As shown in FIG. 1, the cover member 5 is surrounded by a portion covering the opening 13C of the partition penetrating portion 15 so as to be in contact with the insertion body 21, and is attached to the insertion body 21 by a string-shaped member 22 wound from the outside. It is fixed. The string-shaped member 22 may be any member as long as it can be bent, and is preferably a wire member including a wire. The wire member may be a metal wire alone, a resin-coated wire obtained by coating a metal wire such as a twisted wire (registered trademark) with a resin, or a wire entwined with a wire called a molding or the like. When the wire member is used, the cover member 5 can be fixed to the insertion body 21 only by twisting or twisting.
Further, in another aspect (not shown), the cover member 5 surrounds the partition penetrating portion 15 so that the portion covering the opening 13C is in contact with the insertion body 21 and is from the outside (that is, the side opposite to the insertion body 21). It is fixed to the insert 21 by the wound adhesive tape. The adhesive tape may have an adhesive layer provided on one surface of the substrate and the substrate. As the base material, paper, a resin film, cloth or the like can be used, or the above-mentioned non-combustible material may be used. Further, as the pressure-sensitive adhesive layer, for example, an acrylic pressure-sensitive adhesive, a urethane-based pressure-sensitive adhesive, a rubber-based pressure-sensitive adhesive, a silicone resin-based pressure-sensitive adhesive, or the like can be used. Further, a known flame retardant or the like may be blended in the pressure-sensitive adhesive.
In another aspect (not shown), the cover member 5 is installed so that the portion covering the opening 13C of the partition penetrating portion 15 is in contact with the insertion body 21 and is installed from the outside (that is, the side opposite to the insertion body 21). It may be fixed to the insertion body 21 by a fixing member such as a tacker or a screw.
In another aspect (not shown), the cover member 5 may have, for example, a refractory material layer having adhesiveness or an adhesive layer. The adhesive layer of the refractory material and the adhesive layer may form the outermost surface of the cover member 5. That is, the cover member 5 may have at least one of a refractory material layer having adhesiveness on the inside (that is, the insertion body 21 side) and an adhesive layer.

The cover member 5 may cover a part of the sheet-shaped member 3 so that the part of the sheet-shaped member 3 cannot be visually recognized from the outside. Specifically, it is preferable to cover the portion through which the insertion body 21 of the sheet-shaped member 3 is inserted, whereby the design of the compartment penetration portion 15 can be improved and the fire resistance performance of the compartment penetration portion 15 can be improved. Can be improved. As a means for making a part of the sheet-shaped member 3 invisible from the outside, as another aspect (not shown), the cover member 5 covers a part of the sheet-shaped member 3 and a metal foil other than the cover member 5 is used. And the metal leaf composite or the like may be fixed to the end surface 3C of the sheet-shaped member 3 and covered. Further, as a means for making a part of the sheet-shaped member 3 invisible from the outside, as another aspect (not shown), when a part of the sheet-shaped member 3 is covered with the cover member 5, the cover member 5 and the sheet are covered. The gap formed between the shape member 3 and the shape member 3 may be covered with a metal foil other than the cover member 5, a metal foil composite, or the like.
On the other hand, the cover member 5 may cover a part of the sheet-shaped member 3 so as to be visible from the outside. Specifically, as shown in FIG. 2, the cover member 5 may make the end surface 3C of the sheet-shaped member 3 visible from the outside. By making the end surface 3C of the sheet-shaped member 3 visible from the outside with the cover member 5 installed, it is possible to easily perform a visual inspection that the sheet-shaped member 3 is installed in the section penetrating portion 15. Can be done. In FIG. 2, only the end face 3C is visible, but as shown in FIG. 5, a part of the surface 3A of the sheet-like member 3 is exposed, and in addition to the end face 3C, a part of the surface 3A is also exposed. It may be visible. Further, as shown in FIG. 6, when the cover member 5 is fixed to the end surface 3C of the sheet-shaped member 3 to cover the sheet-shaped member 3, or as shown in FIG. 7, the cover member 5 is the sheet-shaped member 3. When the cover member 5 is fixed to the back surface 3B and covers the sheet-shaped member 3, the cover member 5 may have a single or a plurality of holes (not shown) so that the surface 3A of the sheet-shaped member 3 can be visually recognized from the holes.

The cover member 5 is preferably installed so as to be in contact with the sheet-shaped member 3 and the insertion body 21. By installing the cover member 5 so as to be in contact with the sheet-shaped member 3 and the insertion body 21, the opening 13C of the partition portion 11 can be closed by the sheet-shaped member 3 and the cover member 5, and the fire resistance is improved. Can be done.

The cover member 5 is installed so as to form a gap 40 with the sheet-shaped member 3. Since there is a gap 40 between the sheet-shaped member 3 and the cover member 5, the cover member 5 is fixed with a margin for the axial movement of the insertion body 21. By fixing the cover member 5 to the insertion body 21 with a margin, after the sheet-like member 3 and the cover member 5 are installed, the insertion body 21 arranged inside the sheet-like member 3 and the cover member 5 is used as an axis. Even when the cover member 5 is moved in the direction, the margin of the cover member 5 prevents the sheet-shaped member 3 and the cover member 5 from moving together with the insertion body 21. By cushioning the sheet-shaped member 3 and the cover member 5 from moving together with the insertion body 21, it is possible to prevent the sheet-shaped member 3 and the cover member 5 from being displaced from the section penetrating portion 15. That is, with such a configuration, the sheet-shaped member 3 and the cover member 5 can be maintained and continuously arranged at appropriate positions in the compartment penetrating portion 15, and the fire resistance of the compartment penetrating portion 15 can be maintained. Can be done.
There is a gap 40 between the sheet-shaped member 3 and the cover member 5, and the cover member 5 can take various forms as a configuration in which the cover member 5 is fixed with a margin to the axial movement of the insertion body 21. For example, the cover member 5 is made of a material having flexibility and elasticity so that at least a part of the cover member 5 can be bent or bent, and at least a part of the cover member 5 is fixed to the insertion body 21 so as to have slack. The configuration and the like can be mentioned.

The cover member 5 may be made of a single layer of a refractory material layer, may be made of a single layer of a non-combustible material layer, or may have both a refractory material layer and a non-combustible material layer, but may have a non-combustible material layer. It is preferably possessed, and more preferably composed of a non-combustible material layer. Further, a layer other than the refractory material layer and the non-combustible material layer may be provided, and examples of such a layer include a material layer composed of a material other than the non-combustible material, an adhesive layer, and the like.
The cover member 5 preferably includes a metal foil such as an aluminum foil, a glass cloth, a metal foil composite such as a metal foil such as an aluminum glass cloth, and a metal foil composite which is a composite of the glass cloth. These form a non-combustible material layer. Among these, aluminum glass cloth is more preferable from the viewpoint of fire resistance.
The thickness of the non-combustible material layer is not particularly limited, but is, for example, 0.01 to 1 mm, preferably 0.05 to 0.5 mm. When the non-combustible material layer has a thickness equal to or less than these upper limit values, flexibility is imparted to the cover member 5. Therefore, even if the cover member 5 has a non-combustible material layer, for example, the cover member 5 can be wound while being in close contact with the outer periphery of the insertion body 21. In addition, having a thickness equal to or greater than the lower limit makes it easier to secure fire resistance.

The thickness of the refractory material layer is not particularly limited, but is, for example, 0.01 to 1 mm, preferably 0.05 to 0.5 mm. When the refractory material layer has a thickness equal to or less than these upper limit values, flexibility is imparted to the cover member 5. Therefore, even if the cover member 5 has a refractory material layer, it can be wound around the outer periphery of the insertion body 21. In addition, having a thickness equal to or greater than the lower limit makes it easier to secure fire resistance.

The cover member 5 may have a refractory layer having adhesiveness or may have an adhesive layer. The adhesive layer of the refractory material and the adhesive layer may form the outermost surface of the cover member 5.
With the above configuration, the cover member 5 can be fixed to the sheet-shaped member 3 or the insertion body 21 without using a fixing member as a member separate from the cover member 5. Further, by making the refractory material layer itself adhesive, it is not necessary to provide the adhesive layer, so that the configuration of the cover member 5 can be further simplified.
When the cover member 5 is provided with a refractory material layer having adhesiveness or an adhesive layer on the outermost surface thereof, a release sheet may be attached to the outermost surface thereof. The release sheet may be peeled off from the outermost surface during use.

(Thermal expandable resin composition)

Examples of the heat-expandable material include a heat-expandable layered inorganic substance such as a foaming agent that foams when heated, vermiculite, and heat-expandable graphite, and heat-expandable graphite is particularly preferable. By using the heat-expandable graphite, it is appropriately expanded by heating the fire, and the mechanical strength of the expanded residue after the expansion is excellent, so that the fire resistance can be easily improved.

By setting these lower limits or less, it is possible to prevent the thermally expandable material from accidentally expanding due to heating other than a fire. Further, by setting the value to the upper limit or less, it becomes easy to surely expand the heat-expandable material by heating the fire.
Further, the expansion start temperature of the heat-expandable material is such that a predetermined amount (for example, 100 mg) of the heat-expandable material is raised at a constant temperature rise rate (for example, 10 ° C./min), and a force in the normal direction rises. It can be measured by measuring the temperature. The measuring device may be any device as long as it can control the measured temperature and can measure the stress in the normal direction, and for example, a leometer may be used.
The expansion ratio of the heat-expandable member is preferably 3 times or more, and preferably 10 times or more. The upper limit of the expansion ratio is not particularly limited, but is, for example, 70 times, preferably 50 times. When a plurality of refractory material layers having different expansion ratios are laminated on the sheet-shaped member, the expansion ratio may be selected within the above range. Further, for example, the difference between the expansion ratio of the refractory material layer farthest from the outer surface of the partition portion and the expansion ratio of the refractory material layer closest to the outer surface of the partition portion is preferably 10 to 80 times. It is more preferably about 70 times, and even more preferably 30 to 60 times.
The expansion ratio was determined by supplying a heat-expandable member to an electric furnace, heating at 600 ° C. for 30 minutes, measuring the thickness of the test piece, and measuring (thickness of the test piece after heating) / (before heating). It is better to calculate by the thickness of the test piece).

It is preferably in the range of 10 parts by mass or more and 100 parts by mass or less. When the plasticizer is at least these lower limit values, the moldability tends to be good, and when it is at least the upper limit value, appropriate strength is imparted to the molded product.

The total content of the resin component and the plasticizer is preferably 10% by mass or more and 90% by mass or less, more preferably 25% by mass or more and 80% by mass or less, and 40% by mass or more and 70% by mass or less based on the total amount of the resin composition. More preferred. By setting these lower limits or more, the moldability of the heat-expandable member can be improved. In addition, flexibility is ensured, and bending and deformation become easy. Further, by setting the value to the upper limit or less, it becomes possible to blend a sufficient amount of components such as heat-expandable graphite and an inorganic filler.
The total content of the resin component and the plasticizer means the total content of both the resin component and the plasticizer when both are contained, and the resin component alone when the plasticizer is not contained. It means the content.
