One or two or more of synthetic resin sheet, rubber sheet, cloth sheet, gypsum paper, aluminum hydroxide paper, glass fiber non-woven fabric, etc., or a sheet made of waterproof and flame retardant It is.

The core material 3 is made of a synthetic resin foam such as a polyurethane foam, a polyisocyanurate foam, a phenol foam, a vinyl chloride foam, a polyethylene foam, a polystyrene foam, and a urea foam. It is formed by mixing an undiluted solution, a curing agent, and a foaming agent, discharging the mixture to the back side of the front surface material 1 or the back surface material 2, heating, reacting, foaming, and curing. In the core material 3, light-weight aggregates (pearlite grains, glass beads, gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.) and fibrous materials (glass wool, rock wool, carbon fiber, (Eg, graphite) to improve fire resistance and fire resistance.

The inorganic mat B is integrally laminated at least on the back side of the surface material 1 (boundary surface with the core material 3) via the adhesive layer 4, and is mainly used to prevent the building panel A from fire and fire. It functions as an improvement in the properties, an improvement in the flatness of the surface material 1, a reinforcement of the adhesiveness between the surface material 1 and the core material 3, and a mechanical strength of the entire building panel A.

As shown in FIG. 2, for example, the inorganic mat B is a mat formed from inorganic fibers such as glass fiber, ceramic fiber, and rock wool to a thickness of about 0.5 to 5 mm. Containing a thermally foamable carbon component 5. Although not shown, the surface of the inorganic mat B can be fluffed to enhance the adhesion to the core material 3 and the surface material 1 by the anchor effect.

The carbon component 5 mixed therein is made of, for example, a carbon compound such as graphite and carbon black, and when heated, carbonizes and foams to form a heat insulating layer. It prevents conduction. The expansion ratio of the carbon component 5 is about 5 to 80 times.

The adhesive layer 4 is preferably an adhesive type such as a rubber type or a heat-sealing type because the manufacturing process of the building panel A is facilitated. For example, butyl rubber, chloroprene, EVA, styrene / butadiene rubber, high It is composed of at least one of styrene rubber, styrene-based lastmer and the like.

FIG. 3 is an example showing the overall shape of the building panel A according to the present invention. FIG.
(B) and (c) correspond to the cross-sectional view taken along the roll line in FIG.

That is, a decorative surface 6 in which a central portion of the surface material 1 is projected in a square convex shape and a connecting tongue piece 7 are formed, and the connection between the building panels A is performed in four side pieces. This is performed by overlapping the connecting tongue pieces 7.

FIG. 3B shows an example in which the inorganic mat B is also laminated below the connecting tongue 7 of the surface material 1.
(C) is an example of the building panel A from which the inorganic mat B below the connecting tongue 7 is cut off.

Further, in order to confirm fire resistance, an aluminum steel plate having a thickness of 0.5 mm was used as the surface material 1, an isocyanurate foam having a density of 60 kg / cubic meter was used as the core material 3, and a 0.27 mm thick steel was used as the back material 2. A fire protection structural test was conducted using a steel plate and a building panel A having a total thickness of 30 mm as shown in FIG.

As a result, the maximum rear surface temperature of the building panel A body is 146 ° C., and the maximum rear surface temperature of the joint is 10%.
At 3 ° C., the afterflame time was 0 second, and the result was acceptable.

The above is only one embodiment of the building panel A according to the present invention, and the building panel A shown in FIGS. 4 to 9 or a member can be used. That is, FIG. 4 is a cross-sectional view showing another example of the building panel A, and FIG. Example,
FIG. 4B shows an example in which the inorganic mat B is interposed at the boundary surface between the back material 2 and the core material 3, and FIG. 4C shows that the inorganic mat B is also interposed at the center of the core material 3. It is an example of a building panel.

FIG. 5 is an explanatory view showing another example of the inorganic mat B. FIG. 5A shows a perforated shape, and FIG.
Is formed with a cylindrical hole 8. The holes 8 promote the flexibility, plasticity, and elasticity of the inorganic mat B to make it easier to handle, and at the same time, function as a space when the carbon component 5 foams in the event of a fire, etc. Are useful in forming Further, the holes 8 effectively act to enhance the adhesion to the core material 3 by the anchor effect.

The depth of the hole 8 may be determined by penetrating the inorganic mat B as shown in FIG. It can be formed halfway as shown in FIG.
