Description

Building panel for blocking noise {BUILDING PANEL FOR BLOCKING NOISE}

The present invention relates to a building panel for blocking noise, and more particularly, to a building panel for blocking noise with improved soundproofing performance capable of insulating or absorbing sound waves of various wavelengths.

In general, in order to prevent noise generated in a room from leaking out to the outside or to prevent outside noise from entering the room, a soundproofing facility is installed on the inner surface of a wall of a building or on the surface of the wall.

Soundproofing for reducing noise can be divided into sound absorption and sound insulation. Sound absorption means to block noise by absorbing sound wave energy generated from a sound source on the surface or inside of a predetermined object, and sound insulation means to block noise by absorbing sound wave energy generated from a sound source into a predetermined object. It means blocking or reflecting noise so that it does not pass through.

Conventionally, glass fiber or polyurethane foam has been widely used as a representative sound-absorbing material, but in the case of glass fiber, harmfulness to the human body has been confirmed, and its use in residential spaces is limited, and polyurethane foam has a problem that fire hazard is inherent.

In addition, materials such as concrete and bricks, which are widely used as sound insulation materials, have high density and excellent sound insulation effect, but are heavy and have poor workability, so that their use as interior or exterior materials for buildings is limited.

Accordingly, a need has arisen for a new type of building panel capable of maximizing soundproofing performance while compensating for the disadvantages of conventionally used sound insulating materials or sound absorbing materials.

1 is a cross-sectional view of a building panel according to an embodiment of the present invention.

A building panel 100 according to an embodiment of the present invention includes a sound insulation board 110 and at least one exterior board 130 . Figure 1 shows only the components related to the embodiment of the present invention, so those skilled in the art to which the present invention pertains will know that other components may be further included in addition to the components shown in FIG. there is.

The sound insulation board 110 has a form in which metal wires 113 and hollow fibers 115 are disposed on an inorganic material 111 . The inorganic material 111 is cured in the form of a slurry, and the metal wire 113 and the hollow fiber 115 are immersed when the inorganic material is in the form of a slurry, and are fixedly coupled to the inside as the inorganic material is cured.

The inorganic material 111 according to an embodiment of the present invention may be obtained by curing a slurry obtained by mixing alpha hemihydrate, a curing retardant, a glidant, and an acrylic resin in water. The hardened inorganic material forms a sound wave impermeable rigid wall to block sound wave energy generated from the sound source.

The slurry according to an embodiment of the present invention may be prepared by mixing 60 parts by weight of water, 0.5 parts by weight of a curing retardant, 0.2 parts by weight of a fluidizing agent, and 5 parts by weight of an acrylic resin with respect to 100 parts by weight of alpha hemihydrate.

The curing retardant may be at least one or a mixture of at least one of citric acid, tartaric acid, gluconic acid, boric acid sodium citrate and sodium gluconate.

The glidant is added to adjust the viscosity of the slurry and allows the metal wire 113 and the hollow fiber 115 to be easily immersed in the slurry. The fluidizing agent is a polycarboxylate. It may be at least one or a mixture of one or more of a melamine-based and a naphthalene-based glidant.

Acrylic resin is added for a surface coating effect because there may be cases in which the building panel 100 is implemented with the sound insulation board 110 alone without the exterior board 130 to be described below.

The metal wire 113 may be stainless steel machined to a diameter of 0.2 mm to 1 mm. The metal wire 113 may be compressed to have a bulk density of 90 to 170 kg/m ³ by being pressed while being filled in the mold.

Since the metal wire 113 itself is a hard, heavy and high-density material, it serves as a sound insulating material, and can prevent sound waves that are not shielded by the inorganic material from passing through the sound insulation board 110.

In addition, when the metal wires 113 are compressed to the bulk density, non-uniform hollows are formed between the compressed metal wires 113, so that a part of sound wave energy can be absorbed by the hollows.

The hollow fiber 115 may be a polyethylene terephthalate (PET) fiber. The hollow fiber 115 according to an embodiment of the present invention may be manufactured by extruding PET through a spinning nozzle in a state in which PET is heated and melted at a temperature equal to or higher than the melting point, and cooled and solidified. The hollow fiber 115 according to an embodiment of the present invention may be any one of island-in-the-sea hollow fibers and conjugated hollow fibers and multi-leaf hollow fibers.

In the hollow fiber 115 according to an embodiment of the present invention, when a sound wave is incident to a fibrous porous medium, air molecules in internal pores are vibrated by sound pressure. This vibration is converted into heat due to a series of phenomena such as vibration of the fiber structure, heat flow transmitted from the air to the fiber, and viscous resistance generated at the boundary of the air gap or the surface of the fiber, which attenuates sound wave energy and finally reduces noise. will make

The hollow fiber 115 according to an embodiment of the present invention may have a linear density of 6 to 7 denier and a hollow ratio of 20 to 30%. Also, the hollow fiber 115 may be processed into a nonwoven fabric having a bulk density of 500 to 600 g/m ³ and a thickness of 5 mm.

On the other hand, in the embodiment shown in FIG. 1, the layer in which the metal wire 113 is compressed and the non-woven fabric layer made of the hollow fibers 115 are physically separated and laminated, but this is exemplary, and the metal wire 113 It may also be implemented in the form of a plied yarn made by twisting the hollow fibers 115 with each other. The building panel 100 in which the nonwoven fabric layer is formed by twisting the metal wire 113 and the hollow fiber 115 will be described in detail with reference to FIG. 2 .

Sheathing plate 130 is attached to one side or both sides of the sound insulation board (110). Specifically, the exterior plate 130 according to an embodiment of the present invention may be attached only to the opposite direction of the construction surface or attached to both sides of the sound insulation board 110.

Exterior plate 130 according to an embodiment of the present invention is implemented as an interior film, a transfer film, sheet paper, etc. for the purpose of making the appearance of the building panel 100 of the sound insulation board 110 beautiful, or imparting flame retardant and non-combustible performance. It can be implemented as flame retardant fabric paper, flame retardant curtain paper, heat insulation wallpaper, etc.

According to the building panel 100 shown in FIG. 1, the inorganic material 111, the metal wire 113, and the non-uniform hollow formed between the metal wires 113 and the hollow formed inside the hollow fiber 115 have different wavelengths. Since it is possible to block or absorb the sound wave of the sound, it is possible to achieve the effect of maximizing the sound insulation effect.

2 is a cross-sectional view of a building panel according to another embodiment of the present invention.

Sound insulation board 110 according to an embodiment of the present invention may include a ply yarn in which an inorganic material 111 and a metal wire 113 are twisted with hollow fibers 115.

When the nonwoven fabric layer is formed by twisting the metal wire 113 and the hollow fiber 115, the thickness of the sound insulation board 111 can be reduced compared to the case of forming a separate layer as shown in FIG.

On the other hand, in FIG. 2, although a case in which a single-stranded metal wire 113 and a single-stranded hollow fiber 115 are twisted with each other to produce a plied yarn is shown as an example, the metal wire 113 and A plied yarn may be produced by changing the ratio of the hollow fibers 115.

3 is a view for explaining a manufacturing method of a building panel according to an embodiment of the present invention.

A slurry is prepared by mixing 60 parts by weight of water, 0.5 parts by weight of a curing retardant, 0.2 parts by weight of a glidant and 5 parts by weight of an acrylic resin with respect to 100 parts by weight of alpha hemihydrate (S310).

The metal wire and the hollow fiber are immersed in the slurry prepared in step S310 (S320). The metal wire and the hollow fiber may be sequentially or simultaneously immersed in the slurry.

The metal wire and the hollow fiber may be immersed in the slurry after being pressed at a predetermined pressure in a state in which they are put into a mold having a predetermined shape. The shape of the mold corresponds to the shape of the building panel 110 to be manufactured, and the preset pressure is the volume in the case of a metal wire. It may be a pressure such that the density is 90 to 170 kg/m ³ and 500 to 600 g/m ³ for hollow fibers. In particular, in the case of hollow fibers, they may be pressed in a heated state at 200° C. to 250° C. to be molded in a compressed state.

On the other hand, when a single nonwoven fabric layer in which at least one metal wire and at least one hollow fiber are plyed is immersed in a slurry, at least one metal wire and at least one hollow fiber are plied before immersing the nonwoven fabric layer in the slurry, After putting the ply yarn into the mold, it is also possible to first create a single nonwoven fabric layer by pressing it with a predetermined pressure. At this time, the compressed ply yarn may be pressed to have a bulk density of 45.2 to 85.3 kg/m ³ .

When the metal wire is pressurized to have the above bulk density, non-uniform hollows are formed between the metal wires. Since a large number of fine hollows are created and the metal wire is located between the hollows, even if the pressurized metal wire is immersed in the slurry, all The void will not be filled by the slurry.

The slurry in which the metal wire and the hollow fiber are immersed is dried for 3 to 5 hours at a temperature of 70 ° C to 80 ° C. The slurry is cured and the metal wire and the hollow fiber are bound to the inside of the inorganic material. When the manufacturing of the sound insulation board is completed, one side of the sound insulation board Alternatively, exterior plates are attached to both sides (S330).

According to the building panel manufactured by the above-described method, sound waves of different wavelengths can be blocked or absorbed by the non-uniform hollow formed between the inorganic material, the metal wire, and the hollow formed inside the hollow fiber, thereby maximizing the sound insulation effect. You can achieve the effect you can.

Although the embodiments of the present disclosure have been described with reference to the accompanying drawings, those skilled in the art may implement the present disclosure in other specific forms without changing the technical spirit or essential features. can understand that there is Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting. The protection scope of the present disclosure should be construed by the following claims, and all technical ideas within the equivalent range should be construed as being included in the scope of rights of the technical ideas defined by the present disclosure.
