Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an interior wall material, an exterior wall material, a roof material, a ceiling material, a floor material for buildings and structures which require fire resistance.
The present invention relates to a long fireproof panel that can be used as a partitioning material, a fire door, and the like, is lightweight, and has mechanical strength.

[0002]

2. Description of the Related Art Generally, as a fireproof panel for a fireproof structure, there is JP-A-4-237756.

[0003]

However, in a fireproof panel having such a structure, under high heat, the front surface material and the back surface material are deformed in different directions by being pulled toward the heating side due to the difference in heat conduction. Due to this, a gap is created in the connecting part, and heat and flame leak from this part to the other side, and J
There was a defect that the test of IS-A-1304 for a fire resistant structure for 1 hour could not be passed. Further, when the fire-resistant panel is attached to the body with a fixture such as a nail or a screw, the end of the male connecting portion is compressed and deformed by the fastening pressure of the fixture, which makes it difficult to fit. there were.

Further, in a fire resistant panel having a core material of phenol foam alone, the mechanical strength of the end portion of the core material is weak, the bending strength is poor and the wind pressure resistance is poor, and it is necessary to shorten the mounting pitch to the frame, so that the construction efficiency is high. There is a disadvantage in that the cost is significantly lowered and the cost is increased by installing many furring edges. In addition, the adhesion strength between the surface material and the back surface material and the core material is weak, and there is a drawback that the surface material, the back surface material and the core material, in particular, end portions are separated by a small impact.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention interposes a non-combustible groove on the front side of a male connecting portion and a side end face surrounded by a backing material and a core material. The present invention proposes a fire-resistant panel that has improved fire resistance, engagement force, liquid leakage during manufacturing, and significant mechanical strength, as well as improved construction efficiency and cost reduction.

The contact tongue piece 23 has an angle corresponding to the guide pieces 14 and 19, and when the front and back materials 2 and 20 are laminated, it can be stably guided so that the laminated position does not shift, and the dimensional accuracy of the fire-resistant panel 1 is improved. It helps to improve production and ease of production.

The core material 24 is composed of a plastic foam 25 and at least one flank incombustible body 26 interposed on one side surface in the longitudinal direction. The plastic foam 25 is mainly a heat insulating material, a fireproof material, an adhesive, and a reinforcing material. , A cushioning material, a sound absorbing material, a bulking material, and a lightweight material.

As the plastic foam 25, a resole-type or novolac-type phenol foam is used.
A foaming agent, aluminum hydroxide (Al (OH) ₃ ), ammonium polyphosphate, expandable graphite, a curing agent, an inorganic powder material such as calcium silicate or calcium carbonate, etc. are mixed, foamed and cured to a final density of 50- 300
It is formed at the Kg / m ³ position.

Resol-type or novolac-type phenol foams (hereinafter simply referred to as phenol foams) are mainly produced by a continuous foaming molding method, and are compared with other synthetic resin foams (plastic foams). It has nonflammability, low smoke generation, and low toxicity. In addition, the composite material formed by sandwiching this phenol foam on a metal plate is compliant with JIS-
A-1301 (Fireproof test method for wooden parts of buildings), J
It has a fireproof performance that passes the fireproof structure test of IS-A-1302 (fireproof test method of non-combustible structure part of building).

As the foaming agent, a stock solution of phenol foam is used.
When 0 part by weight is used, 2 to 50 parts by weight of the phenol foam stock solution is mixed, for example, methylene chloride, carbonate (powder), etc., and aluminum hydroxide is 100 parts by weight of the phenol foam stock solution. 50 parts for the undiluted solution of this phenol foam
It is mixed in an amount of up to 300 parts by weight and is useful as a flame retardant material, a fire resistant material, and a heat resistant material. For example, the composition has a moisture content of 0 to 30%, a particle size of 10 to 100 μ,
It has a purity of 90% or more. In particular, aluminum hydroxide also helps prevent rust.

Ammonium polyphosphate is used as a reaction control material and a flame retardant material, when 1 to 25 parts by weight of the phenol foam stock solution is mixed with the phenol foam stock solution. The particle size is 30-100 μ. Further, graphite is mixed in an amount of 2 to 30 parts by weight based on 100 parts by weight of the phenol foam stock solution. The effect is that the phenol foam is carbonized at the time of fire to form voids, and the voids are closed with graphite expanded by heating to prevent deterioration of fire resistance performance due to thinning of the meat.

The curing agent is a phenol foam stock solution 10
When the amount is 0 parts by weight, 10 to 50 parts by weight is mixed with the stock solution of the phenol foam, which is an organic phosphoric acid type or a mixture of phosphoric acid type and PSA type, and is free of calcium silicate or calcium carbonate. The equipment is mixed to improve the shape retention and fire resistance of the plastic foam 25.

[0030]

As described above, according to the fireproof panel of the present invention, the mechanical strength of the fireproof panel is significantly improved as compared with the conventional case. Fireproof structure test of building structure (JIS-A-
1304), fire protection test for building fire doors (JIS-A-1
311), fireproof warehouse (JIS-S-1037), etc. The adhesion between the surface material, the back surface material and the core material is strong, and there is no separation between the members. No deformation such as swelling or warpage appears on the surface material or the back surface material. Aluminum hydroxide exerts an anticorrosion function on iron due to its tendency to ionize, and not only protects the front and back surfaces of backside materials, but also
Phenolic foam absorbs water and transports aluminum ions to the wood mouth as the water flows, protecting the most rusty parts in the natural environment. Since the connecting part has a triple insertion structure, the engaging force is strong,
Moreover, since the shape of the fitting portion is a blade shape, a wedge shape, an inclined surface, or the like, the work can be performed very easily. The structure in which the concave-line incombustible body is in contact with the side surface between the front and back surfaces greatly improves the compression strength and fire resistance, and there is no leakage to the side surface of the core material, resulting in a significant improvement in yield by approximately 50%. it can. There are characteristics and effects.
