Abstract

PROBLEM TO BE SOLVED: To provide a building panel having high heat insulation performance even if its core is thinned. SOLUTION: A core 3 is sandwiched between a front material 1 and a back material 2, and a ceramic base heat-insulating paint layer 4 obtained by mixing a residual monomer, a silicate, a pearl salt, a zinc oxide, an emulsion resin, ethylene glycol, water, and ammonium into a latex resin serving as the base is formed on the back of the front member 1. The front material 1 is thereby given high heat-insulation performance, so that even if a building panel A is made thinner than usual, it exhibits high heat-insulation performance, and so that while heatinsulation performance similar to that of the prior art is retained, the core 3 itself of the building panel A can be thinned. Therefore, transportation and construction efficiencies are good, the costs of manufacture and construction can be reduced, and the heat insulating paint layer 4 is not exposed to the surface of the building panel A.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a building panel according to the present invention. As shown in FIG. 1, which is an explanatory diagram showing a sectional view of the building panel A,
A core material 3 is integrally sandwiched between a surface material 1 and a back material 2, and a ceramic heat insulating paint layer 4 is formed on at least the back surface of the surface material 1.

When the surface material 1 and the back surface material 2 are made of a thin metal plate, for example, iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy-plated steel plate, galvalume steel plate,
Extrusion and roll forming of enameled steel sheet, clad steel sheet, fluoroplastic steel sheet, laminated steel sheet (PVC steel sheet, etc.), sandwich steel sheet (damping steel sheet, etc.) , And formed into a predetermined shape by press molding.

When the front surface member 1 and the back surface member 2 are made of a synthetic resin plate, for example, a PVC resin, a polycarbonate resin or the like is formed into a predetermined shape by extrusion molding, press molding, roll molding or the like. Of course, a material obtained by laminating these metal plates and a synthetic resin plate may be used.

Further, particularly, the backing material 2 is made of aluminum-evaporated paper, asbestos paper, kraft paper, asphalt felt, metal foil (Al, Fe, Pb, Cu), synthetic resin sheet, rubber sheet, cloth sheet, gypsum paper, hydroxide Aluminum paper,
It can also be formed from a laminate of one or two or more glass fiber nonwoven fabrics, or a sheet-like material subjected to a waterproof treatment and a flame-retardant treatment.

The core material 3 mainly functions as a heat insulating material, a fireproof material, and a bulking material of the building panel A, and includes polyurethane, polyisocyanurate, phenol, vinyl chloride,
Synthetic resins such as polyethylene, polystyrene and urea and their foams, or inorganic materials such as calcium silicate, calcium carbonate and aluminum hydroxide and their foams, or fibrous mats such as glass fiber, ceramic fiber, rock wool and asbestos It consists of a shape.

The core 3 is integrated with the front surface 1 and the back surface 2 by, for example, utilizing self-adhesion when the core 3 is a synthetic resin foam, and in other cases, It is laminated and sandwiched separately via an adhesive (not shown).

Further, a heat insulating paint layer 4 is formed on the back side of the surface material 1. The heat insulating paint layer 4 is based on a latex resin, and contains residual monomers, silicate, pearl salt, zinc oxide, emulsion resin, ethylene glycol, water,
It is made of a ceramic paint mixed with ammonia, for example, trade name “Tempcoat”. By forming the heat-insulating paint layer 4 on the back surface side of the surface material 1, it is possible to function as the surface material 1 of the building panel A without impairing the weather resistance and design properties of the surface material 1 as it is. .

The heat-insulating paint layer 4 has the above-mentioned composition,
It has a property of reflecting about 75% of the solar radiation and a property of emitting 85% of the remaining 25% of the absorbed radiation, and has a high thermal insulation performance.

Further, about 80% of the heat-insulating paint layer 4 is made up of extremely small hollow ceramic spheres. The hollow ceramic spheres dissipate the remaining 25% of the absorbed radiation energy as the temperature rises. It releases 85% of it.

Moreover, since the air is taken into the hollow ceramic spheres one by one in the heat insulating paint layer 4, the convection of the trapped air particles is restricted, and the transmission of energy is slowed down. It is a non-conductor with excellent thermal energy.

As described above, as the reflection, absorption and transmission progress, the transmission of heat energy passing through the heat-insulating coating layer 4 becomes extremely small and gentle, so that even a thin coating film can be obtained.
It has high heat insulation performance.

Of course, the heat insulating paint layer 4 is excellent in weather resistance such as soundproofing, rustproofing, waterproofing, flameproofing and dew condensation prevention in addition to heat insulating performance.

The heat-insulating paint layer 4 is applied to the surface material 1 by an arbitrary thickness using a method such as a spray gun, a roll coater, and a curtain flow, and is fixed by drying or baking.

That is, FIG. 3 shows an example in which the protective layer 8 is laminated on the surface of the heat insulating paint layer 4, that is, the boundary surface with the core material 3, and this protective layer 8 is made of, for example, a paint such as a fluororesin paint, an acrylic resin, or the like. It is made of a sheet of resin, polyvinyl chloride, or the like, and is coated with the heat-insulating paint layer 4. The heat-insulating paint layer 4 reacts with various chemical substances brought from the core material 3 to achieve the heat insulating performance of the heat-insulating paint layer 4. This is to prevent deterioration.

FIG. 6 shows an example of a building panel A which is a drop-down type and is mainly used for horizontal stretching.

7 and 8 (a) and 8 (b) are cross-sectional views showing examples of large double-sided metal sandwich panels. In particular, FIG. This is an example in which a fireproof packing material 9 having waterproof and fireproof properties is interposed therein, and a waterproof seal material 10 is interposed in the female connecting section 6 to improve the waterproofness and fireproofness of the joint joint.

Further, a building panel A shown in FIG.
Is an example in which a non-combustible member 11 arbitrarily formed so as to conform to the shapes of the male connecting portion 5 and the female connecting portion 6 is mounted in each connecting portion, and the non-combustible member 11 is formed by the building panels A. The joint material is provided with improved fire resistance and fire resistance, and is filled in the ends of the male connecting portion 5 and the female connecting portion 6, so that the core material 3 at the end of the building panel A is filled. Of the core material 3 and the foamability and spreadability of the core material 3 are also improved.
