DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to construction,
It can be used as an exterior wall material, roof material, ceiling material, floor material, partition material, fire door, etc.
The present invention relates to a fireproof panel which is free from deformation such as peeling and has excellent strength.

[0002]

2. Description of the Related Art In general, a number of composite panels in which a core made of a synthetic resin foam is sandwiched between a thin plate-shaped front surface material and a back surface material have been invented, devised, and put on the market.

[0003]

However, in a composite panel having such a structure, the surface material and the back material are deformed in greatly different directions by being pulled toward the heating side due to a difference in heat conduction under high heat. As a result, a gap is formed in the connecting portion, from which heat and flame leak to the opposite side, and J
There was a drawback that the test for the refractory structure of IS-A-1304 for 1 hour could not be passed. Furthermore, this type of composite panel, particularly a composite panel manufactured by discharging a core material in a liquid state, a granular state, or the like, has the following disadvantages. That is, synthetic resin foams such as phenol foam, polyurethane foam and polyisocyanurate foam are unreacted components of components used in forming the core material, and surplus gas components generated by the reaction (chlorine, carbon dioxide, methylene chloride, formaldehyde, steam, The surface of the composite panel is deformed with time, such as swelling or warping, due to a gas such as hydrogen), which greatly reduces the image of the decorative surface.

Further, a composite panel in which phenol foam is simply sandwiched between a front surface material and a back surface material is weak in strength since it is made of a synthetic resin foam as a core material, is inferior in bending strength and wind pressure resistance, and is not suitable for construction. The pitch of attachment to the frame was short, and there was a drawback that the workability was poor. In addition, when a stock solution of a resol-type phenol and a curing agent are mixed, discharged, and reacted and foamed to form a core material, tens of percent of the weight of the condensed water during the reaction is contained in the phenol foam. During the curing period of the product or after the panel is installed, moisture changes into steam due to changes in the outside air temperature, etc., and there is no escape route.Therefore, it remains between the surface material of the composite panel and the core material. There are drawbacks such as swelling and warping that adversely affect the composite panel over time. Further, there is a disadvantage that the bonding strength between the surface material, the back surface material and the core material is weak, and the edge of the surface material, the back material and the core material, particularly the ends, are peeled off by a slight impact. In particular, the generation of surplus gas occurred during a high temperature in summer (time when the surface material was heated).

[0005]

SUMMARY OF THE INVENTION In order to eliminate such disadvantages, the present invention forms JIS by forming an inorganic board on a male / female type connecting portion and greatly improving mechanical strength, fire resistance and engagement force. A fireproof panel having a plurality of air permeable members formed in a plastic foam or at least one of boundaries between the plastic foam and the front surface material or between the plastic foam and the back surface material after passing the one-hour test of the fireproof structure of A-1304. By discharging the gas generated in the plastic foam from the air-permeable member to the outside, the excess gas component of the phenol foam and condensed water are released to the outside, and the decorative surface of the fireproof panel has been swollen, warped, etc. for many years. The present invention proposes a fire-resistant panel having no change in the above.

As the plastic foam 3a, a resol type phenol foam is mixed with a foaming agent, aluminum hydroxide (Al (OH) ₃ ), ammonium polyphosphate, graphite, a hardener, and inorganic materials such as calcium silicate or calcium carbonate. Then, foamed and cured to form a finished density of about 50 to 300 kg / m ³ .

Resol type phenol foam (hereinafter referred to as "resol type phenol foam")
Phenol foam) is manufactured mainly by a continuous foam molding method and has nonflammability, low smoke emission and low toxicity compared to other synthetic resin foams (plastic foam). It is. The metal siding material formed by sandwiching the phenol foam on a metal plate is JIS-A-1301 alone.
(Fire test method for wooden part of building), JIS-A-1
It has a fire protection performance that passes a fire protection structure test of 302 (fire prevention test method for a non-combustible structure portion of a building).

[0011] The foaming agent is a phenol foam stock solution of 10
If it is 0 parts by weight, 2 to 50 parts by weight are mixed with the stock solution of the phenol foam, for example, methylene chloride, carbonate (powder) and the like.

Aluminum hydroxide is mixed with 50 to 300 parts by weight of the undiluted solution of phenol foam to 100 parts by weight of the undiluted solution of phenol foam, and is useful as a flame-retardant material, a refractory material and a heat-resistant material. It is. For example, the composition has a water content of 0 to 30%, a particle size of 10 to 100 μ, and a purity of 90% or more.

Assuming that the stock solution of phenol foam is 100 parts by weight, ammonium polyphosphate is mixed with 1 to 25 parts by weight of the stock solution of phenol foam, and is useful as a reaction control material and a flame retardant. The particle size is 30-100μ.

Assuming that the stock solution of phenol foam is 100 parts by weight, graphite is mixed with 2 to 30 parts by weight of the stock solution of phenol foam. The effect is that the phenol foam is carbonized at the time of fire and voids are formed. However, the voids are closed by the graphite expanded by heating to prevent a decrease in fire resistance performance due to thinning.

[0015] The hardener is a phenol foam stock solution of 10

A permeable member 3c formed on the back surface of the surface material 1.
Is made of a breathable member such as a kite string. The gas permeable member 3c is formed by a surplus gas component (chlorine, carbon dioxide, Gases such as methylene chloride, formaldehyde, steam, and hydrogen) or condensed water at the time of the reaction can be released from the cross section of the fireproof panel A to the outside by the permeable member 3c. For this reason, the front and back surfaces of the manufactured fireproof panel A are free from deformation such as swelling and warpage due to internal gas, and have excellent strength and fireproof performance.
Becomes Of course, plastic foam 3 as shown
Not only the surface material 1 side of a but also an intermediate portion, or the back surface material 2 side, or a plurality of layers may be formed in layers.

As shown in FIG. 3, the air-permeable member 3c forms a very small gap α in the plastic foam 3a. For example, the air-permeable member 3c includes cocoon, cotton, hemp, wool, etc. Fiber, synthetic resin fiber, etc.). More specifically, the minimal gap α formed in the air-permeable member 3c is filled with a surplus gas component (chlorine, carbon dioxide, methylene chloride, formaldehyde, water vapor, hydrogen) in the plastic foam 3a or a gas such as condensed water during the reaction. A communication structure is formed to the end of the mouth of the fireproof panel A so that air can be ventilated. The shape is a linear shape, a net shape, a rod shape, a tape shape, a coil shape, or the like.

More specifically, the air-permeable member 3c is formed by being inserted together when the plastic foam 3a is formed, and is buried by the plastic foam 3a. Since the resin of the plastic foam 3a does not penetrate into the permeable member 3c but is formed only on the outer surface portion of the permeable member 3c, the communicating minute gap α is formed at the center of the permeable member 3c. Is formed.

With the structure of the core material 3 as described above, the front and back surfaces of the refractory panel A after the production are swollen by the internal gas,
A fireproof panel A having no deformation such as warpage and excellent strength and fireproof performance is obtained.

The waterproof packing material 8 is a commercially available material such as polyvinyl chloride, chloroprene, chlorosulfonated polyethylene, ethylene propylene, asphalt-impregnated polyurethane, EPM, EPDM and the like. In addition, it is useful as a function such as a waterproof material and an airtight material.

Here, when a fireproof panel A as shown in FIG. 1 was used as a basic shape, and the front surface material 1 and the back surface material 2 were made of colored steel plates, a measurement test of the internal gas pressure was performed. 0.22 kg / cm
^In contrast to ² , it was 0.02 kg / cm ² in the case where the air-permeable member 3c (the kite string) was formed, and it was confirmed that the decrease was 90% or more. The surface material 1 of the refractory panel A was tested assuming the midsummer when surplus gas is generated.
Was measured in a state in which the color steel plate was heated to about 40 to 80 degrees.
