Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

2 is a cross-sectional view showing a preferred embodiment of a nonflammable panel for a building according to the present invention. As shown in FIGS. 1 and 2, the present invention relates to a nonflammable panel for a building, The incombustible panel for a building which is constructed so as to be arranged on a wall or a ceiling of a building, wherein the magnesia is compression molded in a panel form or the magnesia is compression molded in a panel form or a fiber reinforced cement board (10) formed by molding into a panel shape; A surface material (20) formed by compression molding melamine resin on the front surface of the core material (10) in a panel shape at a high pressure or a low pressure; And a coating layer 30 formed by transferring a thermal transfer film to the outer edge of the core material 10 and the surface material 20.

Magnesia used as a material of the core material 10 is called magnesium oxide (MgO), and its properties are characterized by a high melting point (2800 ° C), an excellent basic resistance and electrical insulation at high temperature, a large thermal expansion coefficient and a high thermal conductivity They are also inexpensive and widely used as heat-resistant materials, high-temperature insulating materials, high-temperature optical materials, and lighting materials.

In order to use such magnesia as a core material (10), it is kneaded with a magnesia powder material to be molded into a standard of a building panel such as a square or a rectangle, and is completed by compression molding in a mold, and has properties excellent in fire resistance, incombustibility, So that the core member 10 is formed.

Also, the fiber-reinforced cement board used as a material of the core material 10 together with the magnesia is formed of the core material 10 so that the structure is dense and has a high density and excellent properties such as water resistance, waterproofness, moisture resistance, durability and incombustibility .

In other words, since the core 10 is made of magnesia or fiber-reinforced cement board, the building panel is not burnt due to the high heat caused by the fire, but is prevented from being deformed due to high heat, The soundproofing is effective in preventing the noise of the building and maintaining the inside temperature of the building completely.

The surface material 20 is formed by molding melamine resin in a panel form at a high pressure or a low pressure on the front surface of the core material 10 to provide a clean appearance of the building panel, thereby improving the appearance of the wall and the ceiling of the building.

The adhesive for bonding the core material 10 and the surface member 20 may be an acrylic, an olefin, a polyurethane, an ethylene-vinyl acetate, an epoxy, or the like, as long as the adhesive is excellent in adhesion to the core 10 made of inorganic magnesia. However, since the polyurethane-based adhesive among the above-mentioned adhesives shows excellent adhesion to inorganic materials, has a wide use temperature range, and is excellent in water resistance, cold resistance, heat resistance, impact resistance and flexibility, (10) and the surface member (20).

The coating layer 30 is transferred to the outer edge of the core material 10 and the surface material 20 so that the outer edge of the core material 10 and the surface material 20 are not exposed to the outside, 30, it is possible to realize a beautiful texture and to prevent the moisture from flowing into the core material 10, thereby preventing damage or breakage of the core material 10 and enabling long-time use.

Further, since the coating layer 30 is formed through the thermal transfer film, no additional curing or drying time is required after the formation of the coating layer 30, so that the operation can be easily performed, thereby achieving various colors while improving workability .

Here, the core material 10 can be easily coated on the core material 10 made of magnesia, which is an inorganic material, by forming fine concavities and convexities having an illuminance of 5 to 30 탆 on the outer edge where the coating layer 30 is transferred and coated, The surface roughness of the core member 10 is improved by improving the surface characteristics of the core member 10 coated with the coating layer 30 so that the coating layer 30 is firmly maintained and peeling or lifting of the coating layer 30 does not occur. Moisture is not penetrated, and waterproofing and moisture proofing are performed to improve the durability of the core 10. [

The reason for forming the fine concavities and convexities to have an illuminance of 5 to 30 mu m is that the effect of improving the surface characteristics due to fine concavities and convexities is difficult to form fine concavities and convexities of less than 5 mu m in the core material 10 made of magnesia And the thermal transfer coating process of the coating layer 30 is not easy when the thickness exceeds 30 μm.

The coating layer 30 is preferably made of a thermal transfer film in which a flame retardant material layer having a thickness of 12 to 25 탆 is interposed between the urethane resin as a flame retardant material and the thermal transfer of the coating layer 30 made of a thermal transfer film The flame retardant layer can be formed on the core material 10 and the surface member 20 together with the print layer formed on the thermal transfer film at the time of coating to improve the durability against fire.

The thermal transfer film is generally composed of a PET film, a release material layer, a top primer layer, a printing layer, and an adhesive layer sequentially stacked, and the flame retardant layer according to the present invention preferably intervenes between the release material layer and the top primer layer. This is not limited in the present invention.

Here, the non-flammable panel for building according to the present invention is arranged on the wall or ceiling of the building construction is the adhesive member to be bonded to the wall or ceiling of the building to the opposite surface on which the surface material 20 of the core material 10 is formed A 40 is formed so that the non-combustible panel for building is constructed on the wall or ceiling of the building.

Therefore, as shown in FIGS. 4 and 5, the conductive layer 43 generates heat by the magnetic action of the high-frequency induction heater, and the heat of the generated conductive layer 43 is transferred to the adhesive layer 45 so that the adhesive layer 45 is instantaneously. As it is melted in the liquid phase and compressed to the wall or ceiling of the building and then cooled after a few seconds, the adhesive force is maintained on the core material 10 and the wall or ceiling of the building.

When the adhesive member 40 can improve the construction efficiency by improving the adhesive force between the building incombustible panel and the wall or ceiling of the building, but requires separate maintenance of the building incombustible panel, the magnetic action of the induction heater again. After melting the adhesive layer 45 to leave the building non-combustible panel and repair work is completed, the detached building non-combustible panel can be used by the adhesive member 40 to be reused after the removal of the building non-combustible panel reuse. It is possible to have the effect of reducing maintenance costs.

In this case, the adhesive member 40 has a thickness of the conductive layer 43 of 1.3 to 2.5 mm, and in contrast to the conductive layer 43, the adhesive layer 45 is preferably formed in a thickness ratio of 1: 0.5 to 0.8. Do.

This is because the thickness of the adhesive layer 45 must be maintained in the above range relative to the conductive layer 43 so that the adhesive layer 45 can be melted when the heat through the high frequency induction heater is transferred to the adhesive layer 45.

More preferably, the thickness of the building non-combustible panel of the present invention bonded through the above-mentioned adhesive member 40 can be provided with the best adhesion efficiency when maintained at a thickness of 1.5 ~ 6.5mm.

The adhesive layer 45 may be formed of a polyvinyl chloride, acrylic, polyolefin, polyester, polyamide, polyurethane, or ethylene vinyl acetate resin. Is preferably.

Meanwhile, as shown in FIGS. 6 and 7, a closing plate 50 is formed on the entire surface of the core 10 between the core 10 and the adhesive member 40, and the adhesive provided on the rear surface of the core 10. The member 40 is formed on the rear surface of the closing plate 50 to block the damage of the core 10 in the melting process of the adhesive member 40.

As shown in FIGS. 8 and 9, the exposure preventing member 60 having the same color as the coating layer 30 is adhered to a gap portion in which a plurality of core materials 10 and surface materials 20 are arranged on the wall or ceiling of the building.
