Description

The present invention relates to a fire / proof panel and a fire door, and more particularly to a fire / fire panel and a fire door having a thermally expandable inorganic fireproof material.

Conventionally, wood materials or metal materials have been used as doors. Of these, the door made of a wood material is suitably used because of its excellent design. However, in the case of a wood material, when a fire broke out, it was easy to burn itself, and there was a problem that similar burning occurred. For this reason, in order to give fireproofing and fire resistance to wooden materials, fireproof doors are made by combining wood boards such as Class A fire doors with glass fiber mixed calcium silicate boards and cement boards. In order to develop fire resistance, there is a problem that the thickness is increased and the weight is increased at the same time.
In order to cope with this problem, a fireproof / fireproof panel and a fireproof door having a thermally expandable fireproof material containing a thermoplastic resin or the like have been proposed (Patent Document 1).

On the other hand, the door is usually hung from a frame provided on the inner periphery of the opening of the building through a hinge or the like so as to be freely opened and closed.
In this case, a certain gap is formed between the frame body and the door, and when the door is warped or deformed when the temperature rises due to a fire, the gap with the frame body becomes large, There is a problem that the flame enters from the one side to the other side and the fire becomes larger.
In order to cope with this problem, a fire door having a thermally expandable refractory material containing butyl rubber or the like has been proposed (Patent Document 2).

Furthermore, in addition to these prior arts, rock wool 50 to 90% by weight, thermally expandable inorganic powder 5 to 25% by weight, sinterable inorganic material 5 to 10% by weight, and organic binder 2 to 10% by weight
A heat-expandable inorganic fiber felt obtained by wet papermaking of a water slurry of the above composition has been proposed so far.
The shape of the thermally expandable inorganic fiber felt changes greatly before and after receiving heat from a fire or the like. Therefore, even after the thermally expandable inorganic fiber felt expands due to heat from a fire or the like, the thermally expandable inorganic fiber felt does not easily collapse after the expansion. The sinterable inorganic material is an essential component.
This sinterable inorganic material is sintered and integrated with the rock wool by heat such as fire. By this sintering integration, it is possible to prevent the thermally expandable inorganic fiber felt after expansion from collapsing in a short time.
From this, it is said that the said thermally expansible inorganic fiber felt can be applied to a fireproof sealing material etc. (patent document 2).

However, instead of the above-described thermally expandable refractory material containing the thermoplastic resin or the like, or instead of the above-described thermally expandable refractory material containing butyl rubber or the like, the above-described thermally expandable inorganic fiber felt is simply used. Then there was a problem.
That is, as in the case of the thermally expandable inorganic fiber felt, a sinterable inorganic material such as borax having a melting point of 75 ° C. or sepiolite having a melting point exceeding 1300 ° C. is used for the thermally expandable inorganic fiber felt. In such a case, the sinterable inorganic material and the inorganic fiber may be sintered and integrated before the heat-expandable inorganic material sufficiently expands due to heat from a fire or the like. Even after the material has sufficiently expanded, the sinterable inorganic material and the inorganic fiber may not be sufficiently sintered and integrated, and the shape retention when exposed to a high temperature for a long time is still insufficient. There was no problem.
The object of the present invention is to prevent the shape and retainability even when exposed to high temperatures for a long time.
It is to provide fireproof panels and fire doors.

As a result of intensive studies to solve the above problems, the inventor has a melting point of 650 to 1000 ° C.

Such ceramic fibers preferably have a melting point of 1300 ° C. or higher from the viewpoint of heat resistance,
If it is 1500 degreeC or more, it is still more preferable.
In the present invention, the term “melting point” means the melting point of a substance that clearly shows the melting point, such as a pure substance, and the like for those that do not clearly show the melting point, such as a mixture.
It shall mean the softening point measured according to SR3103-1.

  The said inorganic fiber can use 1 type, or 2 or more types.

The amount of inorganic fiber used in the present invention is based on the weight of the thermally expandable inorganic refractory material,
It is in the range of 55 to 85% by weight.
When the blending amount of the inorganic fiber is less than 55% by weight, the shape retention of the heat insulating layer is lowered, and when it exceeds 85% by weight, the workability of the thermally expandable inorganic refractory material is lowered.
The amount of the inorganic fiber used in the present invention is preferably in the range of 60 to 80% by weight.

The diameter of the inorganic fiber is usually in the range of 0.01 to 100 μm, preferably 0.1 to 100 μm.
The range is 30 μm. In addition, the inorganic fiber may be a bundle of a plurality of fibers combined with a sizing agent such as a silane coupling agent.

These inorganic fibers can be used alone or in combination of two or more.

Next, the thermally expandable inorganic substance used in the present invention will be described.
The thermally expandable inorganic compound is not particularly limited as long as it expands when heated,
Examples thereof include vermiculite, kaolin, mica, and thermally expandable graphite. Among these, heat-expandable graphite is preferable because the foaming start temperature is low.

The heat-expandable graphite is a conventionally known substance, and powders such as natural scaly graphite, pyrolytic graphite, and quiche graphite are mixed with inorganic acids such as concentrated sulfuric acid, nitric acid, and selenic acid, concentrated nitric acid, perchloric acid, peroxygen, and the like. A graphite intercalation compound produced by treatment with a strong oxidant such as chlorate, permanganate, dichromate, hydrogen peroxide, etc., and is a crystalline compound that maintains the layered structure of carbon. .

  The heat-expandable graphite obtained by acid treatment as described above is preferably further neutralized with ammonia, an aliphatic lower amine, an alkali metal compound, an alkaline earth metal compound, or the like.

The thermal expandable graphite preferably has a particle size in the range of 20 to 200 mesh. Granularity is 2
If it is smaller than 00 mesh, the degree of expansion of graphite is small and a sufficient fireproof heat insulating layer may not be obtained. On the other hand, if the particle size is larger than 20 mesh, there is an advantage that the degree of expansion of graphite is large. It may become difficult to be held by the expandable inorganic refractory material.

As a commercial item of the said thermal expansion graphite by which the neutralization process was carried out, for example, UCAR CARBON
“GRAF GUARD” manufactured by the company, “GREP-EG” manufactured by Tosoh Corporation, and the like.

  The said thermally expansible inorganic substance can use 1 type, or 2 or more types.

The compounding quantity of the thermally expansible inorganic substance used for this invention is the range of 5-30 weight% on the basis of the weight of the said thermally expansible inorganic refractory material used for this invention.
When the blending amount of the heat-expandable inorganic material is less than 5% by weight, the expansion volume after combustion is small, and a sufficient fireproof heat insulating layer cannot be obtained. On the other hand, if it exceeds 30% by weight, the strength of the thermally expandable inorganic refractory material after expansion is lowered.
The amount of the thermally expandable inorganic material used in the present invention is preferably in the range of 10 to 25% by weight.

Next, the inorganic binder used in the present invention will be described.

Examples of the alkali metal oxide include Na ₂ O and K ₂ O.

Among the sinterable inorganic materials used in the present invention, the E glass is preferred because it has a low alkali metal oxide content and has little influence on fireproof doors made of fireproof / fireproof panels.

The sinterable inorganic material used in the present invention has a melting point in the range of 650 to 1000 ° C.
Thereby, even after the thermally expandable inorganic refractory material used in the present invention is expanded by heat such as a fire, the inorganic fibers and the like contained in the thermally expandable inorganic refractory material are maintained in an integrated and unitary shape. In addition to being able to do so, its shape retention is maintained even when exposed to high temperatures for long periods of time.
When the melting point is less than 650 ° C., because the heat-expandable inorganic refractory material sufficiently expands due to heat such as fire, the sinterable inorganic material and the inorganic fiber are integrated by sintering, Inferior shape retention when exposed to high temperature for a long time. When the melting point exceeds 1000 ° C,
Even after the thermally expandable inorganic refractory material has sufficiently expanded, the sinterable inorganic material and the inorganic fiber may not be sufficiently sintered and integrated, and similarly when exposed to a high temperature for a long time. Inferior shape retention.
The melting point is preferably 700 to 900 ° C, more preferably 750 to 850 ° C.

The sinterable inorganic material having a desired melting point can be obtained by adjusting the components contained in the sinterable inorganic material.
For example, in the case of the E glass, specifically, silicon dioxide is 55% by weight, aluminum oxide is 15% by weight, calcium oxide is 15% by weight, magnesium oxide is 5% by weight,
When boron oxide is contained at 10% by weight or the like, the melting point is 700 ° C.

By increasing the amount of calcium oxide, magnesium oxide and the like contained in the E glass, the ratio of covalent bonds such as silicon dioxide contained in the E glass can be reduced. Can be lowered to 700 ° C. or lower.

Conversely, by reducing the amount of calcium oxide, magnesium oxide, etc., the proportion of covalent bonds such as silicon dioxide contained in the E glass can be increased, so the melting point of the E glass is raised to 700 ° C. or higher. It becomes possible.

The compounding quantity of the sinterable inorganic material used for this invention is the range of 5-25 weight% on the basis of the weight of the said thermally expansible inorganic refractory material used for this invention.
When the amount of the sinterable inorganic material is less than 5% by weight or more than 25% by weight, the shape-retaining property is lowered when the thermally expandable inorganic refractory material is exposed to a high temperature for a long time. .
The amount of the sinterable inorganic material used in the present invention is preferably in the range of 10 to 15% by weight.

The shape of the sinterable inorganic material is not particularly limited, and examples thereof include a fiber-shaped body, a wool-shaped body in which the fiber-shaped body is intertwined, and a powder-shaped body.
When a fiber shaped body is used as the sinterable inorganic material, the diameter of the fiber is usually in the range of 0.01 to 100 μm, preferably in the range of 0.1 to 30 μm. In this case, as the fiber shaped body, a plurality of fibers combined into one by a sizing agent such as a silane coupling agent can be used.

For example, the rod method of winding the fiber obtained by softening and drawing the raw material of the sinterable inorganic material, the molten raw material Examples of the method include a pot method that discharges from the nozzle and winds up the obtained fiber. What was obtained by these methods can be obtained as a commercial item.

Moreover, when using a powder-shaped body as said sinterable inorganic material, the average particle diameter of the said powder-shaped body is the range of 5-500 micrometers normally. The powdery body can usually be obtained as a commercial product.

The compounding quantity of the organic binder used for this invention is the range of 5-15 weight% on the basis of the weight of the said heat-expandable inorganic refractory material used for this invention.
When the blending amount of the organic binder is less than 5% by weight, workability for producing the thermally expandable inorganic refractory material is lowered. On the other hand, when the content exceeds 15% by weight, the shape-retaining property is lowered when the thermally expandable inorganic refractory material is exposed to a high temperature for a long time.

Next, a method for producing the thermally expandable inorganic refractory material used in the present invention will be described.
The method for producing the thermally expandable inorganic refractory material is not particularly limited. For example, each component of the thermally expandable inorganic refractory material is formed into a plate shape or a sheet shape by a papermaking method, and the thermally expandable inorganic refractory material. Examples of the method include forming a mixture of each component of the refractory material and an organic solvent, and then removing the organic solvent to obtain a plate shape or a sheet shape.

Among these, from the viewpoint of producing the homogeneous heat-expandable inorganic refractory material, a manufacturing method by a papermaking method is preferable, and among these manufacturing methods by the papermaking method, a manufacturing method by an adsorption molding method is more preferable.

As a manufacturing method of the said thermally expansible inorganic refractory material by a typical papermaking method, the manufacturing method by the next process can be mentioned, for example.
(1) Each component of the thermally expandable inorganic refractory material used in the present invention described above is dispersed in a solvent using an apparatus such as a mixer or a mill to prepare a solvent slurry of each component.
(2) The solvent slurry is made by a paper making machine such as a rot former and formed into a desired shape.
(3) If necessary, the solvent is removed from the solvent slurry by means such as suction, compression, centrifugation, heating, and air blowing.
Through the above steps, the thermally expandable inorganic refractory material used in the present invention can be obtained.

Next, the manufacturing method of the said thermally expansible inorganic refractory material by an adsorption molding method is demonstrated.
An embodiment of this adsorption molding method is exemplified as follows with reference to FIG.
(1) For example, a solvent that does not dissolve each component of the thermally expandable inorganic refractory material is prepared,
A slurry 1 is prepared in which the components of the thermally expandable inorganic refractory material are suspended in such a solvent.
(2) A frame body suction port 2 for sucking the slurry 1 and each component of the thermally expandable inorganic refractory material are separated from the slurry 1 provided on one side of the frame body suction port 2. The slurry is sucked by an adsorption molding device 5 provided with a filtering member 3 for the purpose and a suction device 4 for recovering the solvent from the slurry 1 through the filtering member 3.
(3) Between the frame body inlet 2 of the adsorption molding device 5 and the filtering means 3, for example,
A partition for orienting the inorganic fibers contained in the slurry 1 in one direction can be provided (not shown). Since this partition is provided with one side of each section sufficiently longer than the other side, the inorganic fibers 6 are sequentially deposited from the filtration member 3 side along the direction of the long side in the suction molding apparatus 5. .
For convenience of explanation, in FIG. 1, the length of the inorganic fiber is drawn longer than the actual length.
The partition is pulled out from the frame body suction port 2 after the suction operation is completed or while performing the suction operation, so that a filtered material in which the inorganic fibers are substantially oriented in a certain direction is formed inside the adsorption molding device 5. .
(4) After suction, the solvent contained in the obtained filtrate is removed by means such as suction, compression, centrifugation, heating, and air blowing.
(5) Subsequently, it can be formed into a desired shape using means such as cutting.
Through the above steps, the thermally expandable inorganic refractory material used in the present invention can be obtained.
