Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fireproof sheet waterproof structure applied to a heat insulating waterproof roof or the like in which a waterproof sheet is laid via a heat insulating layer on a frame such as a concrete roof substrate.

[0002]

2. Description of the Related Art In recent years, a technique for roofing construction using a waterproof sheet made of a soft synthetic resin has been adopted for a sloped roof of a general house.

In a roofing structure using a waterproof sheet, for example, as shown in FIG. 3, there is a roofing structure (1) in which a waterproof sheet (13a) is laid via a heat insulating material (12a). In such a structure, the waterproof sheet (13a) may be a contact construction method in which almost the entire area of the waterproof sheet (13a) is bonded to the heat insulating material layer with an adhesive such as a rubber-based or epoxy-based resin, or a waterproof sheet. (13
A part of a) is mechanically fixed to the roof substrate (1), and a large number of the remaining parts are separated by an insulation method or the like.

In such a roofing structure, in order to improve the fireproofness, the fireproofness of the individual components such as the heat insulating material (12a) and the prevention sheet (13a) is improved so that the roofing material as a whole. In general, many methods for improving the fire protection of are used.

For example, it is customary to use a flame-retardant material as the heat insulating material (12a) and mix a flame retardant into the molding material of the waterproof sheet (13a) to improve the fire resistance of the entire roofing material. .

[0006]

However, when a flame retardant or the like is added to the molding material of the waterproof sheet (13a), the physical properties of the sheet itself are deteriorated due to the incorporation of the flame retardant, and the weather resistance and durability are deteriorated. In addition, there is a problem that the production becomes difficult and the cost increases due to the addition of the flame retardant.

When a heat-insulating material (12a) made of a flame-retardant resin foam molding such as phenol resin is used, although the heat-insulating material (12a) itself can be prevented from burning to some extent, Combustion cannot be prevented, and it is difficult to obtain sufficient fireproofness.

On the other hand, in addition to the above, for example, between the heat insulating material (12a) and the waterproof sheet (13a) in the roof material,
A method of interposing a cement-based incombustible board (calcium silicate board, etc.) is also considered.

However, since the non-combustible board is heavy and hard, it is difficult to carry in and lay the material.
Not only is it disadvantageous, but on-site cutting work and construction work become difficult, and in rainy weather, harmful changes may occur due to moisture absorption, so the actual work is currently postponed. .

The present invention has been made in view of the above circumstances, and in a building such as a waterproof roof structure for a sheet, the building material itself such as a waterproof sheet and the surface of the building material can be constructed without flame-retarding. An object of the present invention is to provide a fire-extinguishing paint capable of obtaining a sufficient fireproof property.

[0011]

As a result of repeated and rigorous experimentation and repeated efforts, the present inventor has found an optimum structure capable of achieving the above object and completed the present invention.

That is, the sheet waterproof structure having fireproof property of the first invention comprises a heat insulating layer provided on a building frame,
A fire-extinguishing layer provided on the heat-insulating layer, and a water-proof layer provided on the fire-extinguishing layer and comprising a waterproof sheet, wherein the fire-extinguishing layer contains aluminum hydroxide as a main component, red phosphorus,
The gist of the invention is to include a fire-extinguishing resin composition containing a phosphoric acid ester and a resin binder.

In this sheet waterproof structure, for example, when the waterproof sheet is ignited and starts to burn, the waterproof sheet and the fire-extinguishing resin composition around the combustion area are thermally decomposed, and the thermal decomposition causes aluminum hydroxide in the resin composition. At the same time, a large endothermic reaction occurs due to the thermal decomposition of the above, and at the same time, the extinguishing gas is generated due to the thermal decomposition of the phosphorus component in the fire extinguishing resin composition, and the combustion of the waterproof sheet is suppressed.

As described above, the sheet waterproof structure of the first invention suppresses the combustion of the waterproof sheet by the fire-extinguishing resin composition provided on the back surface side of the waterproof sheet.
Unlike the conventional waterproof sheet itself or the surface of the waterproof sheet having a flame-retardant finish, the physical properties of the waterproof sheet can be favorably maintained, and sufficient weather resistance and durability can be obtained.

In the first aspect of the present invention, the fire-extinguishing resin composition contains 1 to 11 parts by weight of red phosphorus and 5 to 5 parts of phosphoric acid ester.
30 parts by weight, 40 to 70 parts by weight of aluminum hydroxide,
It is preferable to adopt a constitution in which the resin binder is contained in an amount of 3 to 20 parts by weight.

That is, when this structure is adopted, the above-mentioned fire prevention performance and the like can be more reliably obtained.

The second aspect of the present invention is to add ammonium polyphosphate as a suitable component to the fire-extinguishing resin composition according to the first aspect.

That is, the fireproof sheet waterproof structure of the second aspect of the present invention is a waterproof sheet provided on a building frame, a heat insulating layer, a fire extinguishing layer provided on the heat insulating layer, and a fire extinguishing layer provided on the fire extinguishing layer. The fire-extinguishing layer comprises a fire-extinguishing resin composition containing aluminum hydroxide as a main component, red phosphorus, phosphoric acid ester, ammonium polyphosphate and a resin binder. .

In the seat waterproof structure of the second invention, as in the seat waterproof structure of the first invention, combustion of the waterproof sheet can be suppressed and sufficient light resistance and durability can be obtained.

In particular, in the second aspect of the invention, since the fire-extinguishing resin composition contains ammonium polyphosphate, the decomposition of the phosphorus component efficiently generates a fire-extinguishing gas to more reliably burn the waterproof sheet. Can be suppressed.

In the second aspect of the present invention, the fire-extinguishing resin composition comprises 1 to 11 parts by weight of red phosphorus, 5 to 30 parts by weight of phosphoric acid ester, 5 to 25 parts by weight of ammonium polyphosphate, and aluminum hydroxide. Is preferably 40 to 70 parts by weight and the resin binder is 3 to 20 parts by weight.

That is, when this structure is adopted, the above-mentioned fire prevention performance and the like can be obtained more reliably.

Further, in the waterproof structure for a seat according to the present invention,
It is preferable to employ a configuration in which the fire-extinguishing layer is formed by a fire-extinguishing sheet member in which the fire-extinguishing resin composition is laminated on a base sheet.

That is, when this construction is adopted, the fire extinguishing layer can be formed by laying the fire extinguishing sheet member on the heat insulating layer, so that the workability can be improved.

The structure of the present invention will be described in detail below.

The sheet waterproof structure having fireproof property of the present invention is applied to a sheet waterproof roof structure as shown in FIG. 1, for example.

In this sheet waterproof roof structure, a heat insulating layer (12), a fire extinguishing layer (20) and a waterproof layer (13) are laminated on a roof substrate (11) as a building frame.

Here, the roof substrate (11) is, for example, reinforced concrete (RC) or lightweight foam concrete (AL).
C), a concrete plate such as precast concrete (RC), or the like, and has a sloping roof shape with a slope, a horizontal flat roof shape without a slope, or an arched roof shape. It may be present, and the material and shape are not particularly limited.

The heat insulating material (12) which constitutes the heat insulating layer (12)
Examples of a) include polystyrene, polyvinyl chloride,
Those made of resin foam such as polyurethane and polyethylene can be preferably used, and among them, polystyrene resin foam is particularly preferable.

The waterproof sheet (1 which constitutes the waterproof layer (13)
As 3a), soft synthetic resin made of polyolefin resin such as polyvinyl chloride resin, polyethylene resin, polypropylene resin or the like, or synthetic rubber can be used. Among them, polyolefin resin or polyvinyl chloride can be used. Those made of soft synthetic resin such as resin can be preferably used. In addition, as the waterproof sheet (13a),
Besides a single sheet made of a single synthetic resin, a composite sheet in which a plurality of synthetic resins are laminated and formed, or a sheet in which a reinforcing layer or the like is interposed may be used.

The fire-extinguishing layer (20) is a fire-extinguishing sheet member (2).
0a). Fire extinguishing sheet member (20
a) is a base sheet (21), as shown in FIG.
The fire-extinguishing resin composition (22) laminated on the upper surface thereof.

In the present invention, the fire-extinguishing resin composition (2
2) is composed of a coating composition containing red phosphorus, phosphoric acid ester, aluminum hydroxide, and a resin as a binder.

The content of red phosphorus in the resin composition (22) must be set to 1 to 11 parts by weight (1 to 11% by weight), and the lower limit is preferably 2 parts by weight (2% by weight).
As described above, it is preferable to set the upper limit value to 8 parts by weight (8% by weight) or less, and more preferably set the upper limit value to 4 parts by weight (4% by weight) or less. That is, if the content of red phosphorus is too small, the amount of fire-extinguishing gas generated during combustion becomes insufficient as described later, and it may be difficult to obtain good fire protection. Conversely, if the content of red phosphorus is too high,
No corresponding effect is recognized and it is meaningless, which is not preferable.

The weight percentages in parentheses are those in the dry state in which the solvent is not contained (hereinafter the same).

Further, the content of the phosphoric acid ester in the resin composition (22) needs to be set to 5 to 30 parts by weight (5 to 30% by weight), and the lower limit is preferably 7 parts by weight (7 parts by weight). %) Or more and the upper limit value is 20 parts by weight (20% by weight) or less, and more preferably the upper limit value is 15 parts by weight (15% by weight) or less. That is, when the content of the phosphoric acid ester is too small, the amount of fire extinguishing gas generated during combustion becomes insufficient, and it becomes difficult to obtain good fire protection. Not only that, since the phosphoric acid ester also functions as a plasticizer, it is not possible to obtain good flexibility as a resin composition paint due to the lack of a plasticizer, and the phosphoric acid ester is difficult to apply when applied to the base sheet (21) or the like. It may be difficult to obtain sufficient coating properties. On the contrary, if the content of the phosphoric acid ester is too large, the effect commensurate with the content is not recognized and it becomes meaningless, which is not preferable.

The content of aluminum hydroxide in the resin composition (22) is 40 to 70 parts by weight (40 to 70 parts by weight).
70% by weight), and preferably the lower limit is set to 45 parts by weight (45% by weight) or more and the upper limit is set to 60 parts by weight (60% by weight) or less. That is, when the content of aluminum hydroxide is too small, the endothermic amount during combustion becomes insufficient as described later, and it may be difficult to obtain good fireproofness. On the contrary, if the content of aluminum hydroxide is too large, not only the effect commensurate with it but also the coating property may be deteriorated, which is not preferable.

Further, in the present invention, aluminum hydroxide having an average particle size of 3 to 100 μm, preferably a lower limit value of 15 μm or more, more preferably 30 μm or more and an upper limit value of 80 μm or less is used. That is,
If the aluminum hydroxide is too small, the viscosity becomes too high, and it becomes difficult to obtain good coating characteristics,
Not preferable. If it is too large, it cannot be uniformly applied, which is not preferable.

Further, in the present invention, the resin composition (22)
Although a resin is used as the binder in the above, a flame-retardant resin having a self-extinguishing property such as an acrylic resin, a polycarbonate resin, or a polyvinyl chloride resin can be preferably used.

Further, the content of the binder in the resin composition (22) must be set to 3 to 20 parts by weight (3 to 20% by weight), and the lower limit is preferably 5 parts by weight (5).
Or more, and the upper limit is 15 parts by weight (15% by weight) or less, more preferably the upper limit is 12 parts by weight (12% by weight).
The following settings are recommended. That is, when the content of the binder is too small, the binding properties of the respective contained components and the adhesiveness to the base sheet (21) become insufficient, which may make it difficult to use as a paint. On the contrary, if the binder is too much, the content of other essential components such as red phosphorus, phosphoric acid ester, and aluminum hydroxide decreases accordingly.
It is not preferable because it becomes difficult to obtain sufficient fireproofness.

In the resin composition (22) of the present invention,
It is preferable to include ammonium polyphosphate as a suitable component. That is, in this case, fire-extinguishing property can be further improved by generation of extinguishing gas due to decomposition of ammonium polyphosphate.

When ammonium polyphosphate is contained, its content relative to the resin composition (22) is 5 to 25 parts by weight (5 to 25% by weight), more preferably the lower limit value is 10.
The upper limit value is 18 parts by weight (18% by weight or more).
(Wt%) It is better to set below.

In the resin composition (22) of the present invention, since it is usually used as a paint, a solvent for the resin binder is included.

As the solvent, any suitable solvent may be used in consideration of the kind of the resin binder and the viscosity of the paint to be obtained. For example, methanol containing methanol as a main component and containing isopropyl alcohol and water is used. A system solvent can be used.

The blending amount of the solvent may be appropriately set in consideration of the type of the solvent, the viscosity of the paint to be obtained, etc.
It is customary to set about 10 to 40 parts by weight with respect to the suitable parts by weight of each of the above components.

Further, the resin composition (22) of the present invention may contain other additives in addition to the above essential and preferred components. For example, an inorganic filler, an extender, or the like other than the above may be appropriately added.

In the present invention, for example, as shown in FIG. 2, the fire extinguishing sheet member (2) is prepared by applying the coating composition comprising the resin composition (22) having the above-mentioned constitution to the base sheet (21).
0a).

As the base sheet (21) of the sheet member (20), one made of a metal sheet such as aluminum foil or styrene steel foil, or one made of woven or non-woven fabric such as metal fiber or glass fiber is used. In particular, aluminum foil can be preferably used.

[0048] In the present invention, the coating amount to the base sheet (21) or the like in extinguishing resin composition (22), 100 to 2000 g / m ² in wet state, preferably a lower limit of 300 g / m ² or more, the upper limit Value is 700g /
It is better to set it to m ² or less. In other words, the coating thickness
It is good to set it to 0.1 to 2.0 mm in the wet state.
That is, when the coating amount of the composition paint is too small,
It may not be possible to obtain sufficient fire protection. On the contrary, if the coating amount is too large, not only the effect corresponding to it cannot be obtained, but also because the coating amount is large, the workability may be deteriorated, which is not preferable.

In the present invention, when the sheet waterproof roof structure shown in FIG. 1 is formed, the heat insulating material (12a) as the heat insulating layer (12), the fire extinguishing sheet member (20) and the waterproof are provided on the roof substrate (11). Waterproof sheet (13) as layer (13)
It is possible to adopt a construction method in which a) is sequentially constructed.

In order to improve the workability of construction, the fire extinguishing sheet member (20) is previously formed on the heat insulating material (12a).
Prepare a heat insulating material with a sheet that is laminated and integrated,
At the construction site, it is also possible to adopt a construction method in which the heat insulating material with a sheet is laid on the roof substrate (11) and then the waterproof sheet (13a) is laid.

In many cases, the waterproof sheet (13a) is partially covered with the roof substrate (1) at a key part of the sheet (13a).
Although it is laid by the insulation construction method so as to be fixed to 1), it may be laid by the adhesion construction method in which almost the entire area of the sheet (13a) is adhered.

In the sheet waterproof roof structure shown in FIG.
When the waterproof layer (13) burns due to scattering of the burned material on the waterproof layer (13), the waterproof sheet (13a) and the fire-extinguishing resin composition (22) around the combustion area are thermally decomposed. . At this time, an endothermic reaction occurs due to the thermal decomposition of aluminum hydroxide in the composition, the thermal decomposition of the waterproof sheet (13a) is suppressed, and the generation of combustible substances is suppressed. At the same time, a fire-extinguishing gas is generated by the thermal decomposition of the phosphorus component in the fire-extinguishing composition (22), and the combustion of the waterproof sheet (13a) is suppressed. Particularly, the fire-extinguishing resin composition (22) of the present invention
In, since the content of aluminum hydroxide is high,
Excellent combustion suppression effect is exhibited by a large endothermic reaction,
Combustion is surely suppressed.

As described above, in the waterproof sheet structure of the present invention, the unique fire-extinguishing resin composition (22) is arranged on the back surface side of the waterproof sheet (13a) to suppress the combustion of the waterproof sheet (13a). Therefore, unlike the conventional one in which the waterproof sheet itself or the surface of the waterproof sheet is subjected to the flame-retardant treatment, the physical properties of the building material such as the waterproof sheet (13a) can be well maintained and sufficient durability can be obtained. Obtainable.

In the present invention, the fire-extinguishing resin composition (22) is applied to the heat insulating material (12a) and the heat insulating layer (12) by a coating process or the like without using the base sheet (21). , May be directly provided, and in that case, the same effect as described above can be obtained.
