The present invention relates to an anti-noise material and a method of manufacturing the same, and more particularly, it is possible to ensure a leveled and objective sound insulation performance due to the production of a standardized anti-noise material, can be recycled without additional pollution during disposal It relates to an environmentally sound noise preventing material and a method of manufacturing the same.

Only 20 years ago, the single-family homes were the main form of housing in Korea. In the case of single-family homes, at most two or three households lived in one house, the noise was not severe and they lived with mutual understanding among neighbors. As quality improves, there is an increasing demand for a pleasant living environment and the maintenance of personal privacy.

On the other hand, floor impact sounds are generated between floors of multi-family houses due to changes in the construction structure such as steel frame input and slab thickness reduction due to high-rise housing, and residents' dissatisfaction with such floor impact noise is increasing. . Here, the floor impact sound refers to the noise transmitted from the floor by the impact source, such as walking or falling objects, through the interlayer solid medium such as the floor or the pillar. In general, apartments or apartment buildings are composed of upper and lower floors, bounded by concrete slabs, and the impact sound generated by striking the upper floors in turn impacts the floor concrete slab through the floor finishing layer, boiler pipe layer, and foam concrete layer. This is passed. The floor impact sound is classified into a light impact sound generated by walking or a light object drop, and a heavy impact sound generated by a child running, etc., and a person living in the lower floor by the floor impact sound receives stress due to noise.

The fundamental solution to reducing these floor shocks is to make no noise, but it is almost impossible in real life, and the noise is distributed to absorb the floor impact sound by dispersing and absorbing the floor impact sound in the process of transferring the impact sound to the concrete slab. To prevent it. In recent years, quarrels have frequently occurred between residents and apartment complexes, such as civil complaints caused by floor shocks.As a result, the government applied for business plans from April 23, 2004. It is regulated to satisfy the standard of 58, and from July 2005, it will be regulated to meet the minimum standard of 50% of weight impact sound.

On the other hand, look at some of the ondol structure of a house having a structure for preventing noise is as follows. The most common ondol structure is to form a sound insulation layer by mixing lightweight foam concrete alone or by mixing sand and styropol particles on a foundation slab, arranging a heating hot water pipe thereon, and then placing a mortar finishing layer composed of sand and cement. to be. However, such an ondol structure has a disadvantage in that the sound insulation and thermal insulation performance of the light-impact foamed concrete used for the sound insulation layer is greatly reduced, and cracks occur during the concrete curing process after construction.

Another ondol structure includes a case in which a sound insulation layer made of styrofoam and a gravel crushed layer, a heating hot water pipe for heating, and a mortar finishing layer are sequentially stacked on a foundation slab. In the case of the ondol structure, although the thickness of the sound insulation layer is changed, it is not sufficient in terms of the performance against the floor impact sound, and although the hole is vertically formed in the styrofoam and mortar pillars are installed there, the sound insulation is also poor in most constructions. The company is avoiding its use.

Recently, an ondol structure has been proposed in which a rubber sheet or a rubber crushed material is installed on a foundation slab and a lightweight foam concrete is poured to form a sound insulation layer. However, such an ondol structure is not only very satisfactory in terms of sound insulation performance, but also has a construction difficulty such as adding a work of assembling or taping the rubber sheet one by one, and pouring lightweight foam concrete under the rubber sheet during pouring.

As described above, when looking at the above-described ondol structure, conventional soundproofing materials for sound insulation are manufactured and not installed on the ondol, but the sound insulation layer is formed by installing gravel or mortar columns on styrofoam or rubber sheet during construction. That is, there was no separate noise prevention material for sound insulation or sound insulation only. Accordingly, when installing the sound insulation layer for preventing noise during the construction of the building, there is a disadvantage that a number of operations must be performed to install each component according to the components constituting the sound insulation layer. In addition, since each component has a difference in composition ratio or thickness depending on the operator to install the equipment, the soundproofing performance is not uniform in each installation because it is not standardized, the performance was often unreliable.

To supplement this problem, standardized sound insulation or sound absorbing materials and methods for manufacturing the same are presented as follows.

Korean Patent Laid-Open Publication No. 2003-0013495 discloses "a method for producing a sound absorbing material between a layer of multi-family housing using a waste tire rubber chip and a cork powder, and a product thereof." A method of molding from a mold to a press is used. However, when the sound absorbing material is manufactured by such a manufacturing method, since the rubber chip and the cork powder are integrally formed, there is a disadvantage in that recycling after construction is difficult.

Korean Unexamined Patent Publication No. 2003-0008801 describes a "building material including waste ethylene vinyl acetate and a method of manufacturing the same", and includes 50 to 85% by weight of foamed ethylene vinyl acetate and 15 to 50% by weight of polyurethane. And vibration damping materials. However, the sound insulation and vibration damping materials manufactured in this way may be difficult to mix the two polymer materials having different molding methods, and the disposal of the sound insulation and vibration damping materials is not only difficult to recycle, but also the mixing of polymer materials having different physical properties. As a result, toxic gases or pollutants may be emitted.

Accordingly, it is possible to develop a method for manufacturing a noise preventing material that can sufficiently sound and block the noise between floors, form its standardized form, and prevent its performance from changing according to workers during building construction. There is a need. In addition, there is a need to develop a method for manufacturing a noise preventing material that can recycle each component at the time of disposal and does not emit toxic substances by incineration or the like.

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

1 is an exploded perspective view of a noise suppression material according to a first embodiment of the present invention, Figure 2 is a cross-sectional view of the noise suppression material of FIG.

This noise prevention material 1 is accommodated in the soundproof board body 10 which has the at least 1 soundproof hole 15, the cover plate 20 couple | bonded with the upper part of the soundproof board body 10, and the soundproof hole 15. It includes a plate-shaped soundproof panel 30.

Here, the soundproof plate body 10 and the cover plate 20 is formed of a first soundproofing material having a soundproofing and sound absorption effect to prevent noise, the soundproof plate body 10 is formed to a thickness of 14 to 30mm, the cover plate ( 20) is formed to a thickness of 6 to 20mm, the soundproof plate body 10 is 16 to 27mm in thickness, the cover plate 20 is preferably formed to a thickness of 8 to 15mm in order to achieve the optimal sound insulation effect. .

In addition, the cover plate 20 may be made in the form of a thin plate, and in some cases may be made in the form of a thin film. When the soundproofing effect is sufficient as the first soundproofing material and the second soundproofing material, the cover plate 20 needs to be made as thin as possible. In this case, the soundproof function of the cover plate 20 itself may not be sufficient. Can be. Therefore, in this case, the cover plate 20 is formed as thin as possible, and only needs to perform a covering function, and can also perform a function of covering a thin film type cover plate, so that a thin film type cover plate can also be used. At this time, the thickness of the cover plate 20 may be 0.1 ~ 6mm, and because of the specificity that the construction site is used the noise prevention material is required, the thickness of the cover plate 20 is more preferably 0.5 ~ 6mm It is more preferable that it is 1.0-6 mm.

On the other hand, if the soundproof plate body 10 and the soundproof panel 30 alone is sufficient noise function, the function of the cover plate is to prevent the soundproof panel body 10 and the soundproof panel 30 is separated from the main purpose, An anti-noise material without a cover plate can be constructed. In this case, in order to prevent the soundproof panel body 10 and the soundproof panel 30 from being separated, by taping at least a part of an outer boundary of the soundproof panel 30 accommodated in the soundproof hole of the soundproof panel body 10. The soundproof plate body 10 and the soundproof panel 30 can be combined. The outer boundary portion refers to a place where the sound insulation plate body 10 and the sound insulation panel 30 are viewed from the outside in contact with each other.

When the sound insulation panel body 10 and the soundproof panel 30 are sufficient for the noise function, the soundproof panel body 10 and the soundproof panel body 10 are not separated from each other in order to prevent the soundproof panel body 10 and the soundproof panel 30 from being separated. The soundproof plate body 10 and the soundproof panel 30 may be combined by applying an adhesive to a part or all of at least one side to which the) is bonded. Of course, in this case, the cover plate 20 may be absent.

The first sound insulation materials used for the production of the sound insulation board body 10 and the cover plate 20 include EVA, EPS, PETG, PE, PSP, PP, rubber plates, urethane, and the like. Here, EVA (Ethylene Vinyl Acetate Copolymer) is a copolymer resin of ethylene and vinyl acetate developed by Hanwha Chemical for the first time in Korea in 1986, and has excellent transparency, flexibility, low temperature brittleness, etc. It is used as a raw material resin such as extrusion coating, and has attracted attention as a substitute material for polyvinyl chloride (PVC) due to its excellent ductility.

EPS is a polystyrene foam, generally known under the trade names Styrofoam or Styropol, and is most widely used as a material for the noise suppression material (1). Foamed polystyrene is a foamed product in which hydrocarbon gas, such as pentane or butane, is injected into a polystyrene resin and then inflated with steam, and 98% of the volume is air and the remaining 2% is a resin. Styrofoam is a styrene polymer or copolymer containing a blowing agent and is supplied in the form of small beads having a diameter of 0.2 mm to 0.3 mm or cylindrical pellets having a length of about 2.5 mm and a diameter of about 0.6 mm depending on the type. do. These foamed polystyrenes do not use freon gas, which causes ozone depletion, reduce global warming, greenhouse effect, and gas emissions that cause acid rain, and do not contaminate groundwater because methane is not generated when buried in the ground. Even if burned, it only emits water and carbon dioxide, so it does not generate harmful gases.

Polyethylene Terephthalate Glycol (PETG) is a plastic foam material mainly used for merchandise showcases and indoor transparent walls. Until now, PS, PP, PVC, and PU have been used a lot, but PS and PVC are regulated due to environmental hormone issues. Accordingly, polyesters, which are free of environmental hormone-like substances in the polymer, are not dangerous in the manufacturing process and have no problem of incineration, have been spotlighted.

There are two types of polyethylene (PE), LDPE (low density polyethylene) and HDPE (high density polyethylene), both of which are mainly used in the manufacture of films and bottles. HDPE is more robust, and polyethylene is suitable for use with frozen foods.

PSP (Polystyrene Paper) is a plastic resin that is used in various fields such as coating fabric, printing lamination fabric, board fabric, fabric for construction materials, fabric for industrial packaging, color fabric, and tray fabric. It is mainly used for the manufacture of insulation materials.

PP (polypropylene) is most used among plastic resins and can be extruded, blow molded, injection molded, compressed, and vacuum molded. In addition, it can be made of fibers, films or various colors or transparent foam, mainly used in the form of a film such as wrapping paper. PP is more flexible than PE, and most plastic boxes are made of polypropylene.

All these various materials can be used for the production of the soundproof plate 10 and the cover plate 20, of which is most preferably made of styrofoam. This is because Styrofoam has the following characteristics in terms of insulation, processing, flame retardancy, water resistance, and sound insulation as building materials. First, since styrofoam has a very low thermal conductivity, the effect of blocking external or internal heat is great, so it is excellent in cold weather. And it can be cut as desired with knife, saw, heating wire, etc., and it is easy to attach and fix with adhesive or nail. In addition, it does not burn well and can reduce the risk of fire. Since it is formed as an independent airtight bubble, the amount of absorption is extremely low even if it is put in water for a long time as well as the passage of moisture. Finally, since it blocks noise from the outside and absorbs the noise inside, it is used for walls and ceilings of homes, factories, offices, and listening rooms.

In particular, according to the specification of the Institute of Construction Technology, Styrofoam 4 is used in this embodiment, and the properties of Styrofoam 4 are as follows. First, Styrofoam 4 has a density of 15kg / m³ or more, a thermal conductivity of 0.043 W / mk or less, 0.037 kcal / mh ° C or less, bending strength of 15 N / cm² or 1.5 kg / cm² or more. Compressive strength is not less than 5 N / cm² or more than 0.5 kg / cm², absorption is less than 1.5 g / 100cm², and the flame should be extinguished within 3 seconds during combustion, so that there is no dregs and no burning above the limit of combustion.

Meanwhile, the soundproof plate body 10 and the cover plate 20 may be manufactured using the same material among the above-described first soundproofing materials, or may be made of different materials, respectively, but it is preferable to use the same material. After construction, when the deformation of the noise prevention material 1 occurs due to a change in external pressure or temperature, the degree of deformation is similar when the soundproof plate body 10 and the cover plate 20 are made of the same material. This is because the soundproof plate body 10 and the cover plate 20 can be prevented from being separated from each other as much as possible. However, when the sound insulation plate body 10 and the cover plate 20 are made of different materials, the shrinkage rate is different, so that the sound insulation plate body 10 and the cover plate 20 are likely to be separated from each other.

On the other hand, the plurality of sound insulation holes 15 formed in the sound insulation plate body 10, as shown in Figs. 1 to 2, is formed in a rectangular cylindrical shape, may be formed as a single groove, as shown in Figs. As shown, it may be divided into two to four may be formed in plurality. The sound insulation hole 15 may be integrally formed at the time of injection foam molding of the soundproof plate body 10, and the soundproof plate body 10 may be formed into a plate shape, and then pressurized by the soundproof plate body 10 with a hot rod of a square plate. It may be. At this time, when the sound insulation hole 15 is formed by using a hot rod, the sound insulation hole 15 region is compressed by heat, and thus there is an advantage that strength is reinforced.

The soundproof panel 30 accommodated in the soundproof hole 15 of the soundproof plate body 10 is made of a plate shape using a second soundproof material having a soundproofing and sound absorption effect, although different from the first soundproof material.

Here, as the second soundproofing material, nonwoven fabric, paper including corrugated paper, scrubber, mineral wool (mineral wool), fabrics including felt or cotton or wool, synthetic resin, sawdust, cork, waste tire, waste vinyl, waste plastic, Use ocher, soil, etc. In this case, in the case of the second soundproofing material such as nonwoven fabric, corrugated cardboard, and cloth, one or several sheets may be stacked and accommodated in the soundproofing hole 15 without a separate manufacturing process, but sawdust, cork, waste tire, waste vinyl, waste In the case of the second soundproofing material such as plastic, ocher, earth, etc., a separate soundproofing panel 30 is manufactured to a size that is accommodated in the soundproofing hole 15 by pressing the mold. In the case of using sawdust, cork, waste tires, waste plastics, waste plastics, and soil as the second soundproofing material, by mixing jade powder or loess, the soundproof panel 30 is manufactured, so that far infrared rays which are good for the body are emitted. The soundproof panel 30 may be manufactured by mixing two or more second soundproof materials. In addition, even when the nonwoven fabric, cloth, and corrugated cardboard is used as the soundproof panel 30, the soundproof panel 30 may be provided by alternately accommodating one or more of the nonwoven fabric, cloth, and corrugated cardboard in the soundproof hole 15. Of course.

Meanwhile, sand, sawdust, cork, waste tires, waste vinyl, waste plastics, ocher, soil, etc. are sprayed in the form of powder 40 in the sound insulation hole 15 in which the sound insulation panel 30 is accommodated, and then the cover plate 20. Can be combined to finish. Injecting the powder 40 such as sand, sawdust, cork, waste tire, waste vinyl, waste plastic, loess, soil into the soundproof hole 15 is the soundproof panel 30 and the soundproofing in the soundproof hole 15. By eliminating the space between the balls 15 as much as possible, to improve the sound insulation effect.

Looking at the process of manufacturing the noise preventing material (1) by this configuration as follows with reference to FIG.

First, the soundproof plate body is manufactured from the first soundproofing material (S10). The manufacturing method is somewhat different depending on what the first soundproofing material is, but if the first soundproofing material is styrofoam, the soundproof plate body 10 is manufactured by foaming at high pressure. At this time, when the sound insulation hole 15 is not integrally formed, the sound insulation plate body 10 is pressurized with a hot rod to form the sound insulation hole 15 (S20).

On the other hand, the soundproof plate body 10 may be formed of a soundproof hole 15 integrally from the beginning. In this case, the process of forming the sound insulation hole 15 by pressing the sound insulation plate body 10 with the hot rod (S20) may be omitted.

In addition, when the cover plate 20 made of the first soundproofing material is required, the cover plate 20 is made of the first soundproofing material (S10). The manufacturing method is somewhat different depending on what the first soundproofing material is, but when the first soundproofing material is styrofoam, the cover plate 20 is manufactured by foaming at high pressure.

In the case of the second soundproofing material formed in the form of a plate such as nonwoven fabric, cloth, corrugated cardboard, etc., the soundproofing panel 30 is cut according to the size of the soundproofing hole 15, and sawdust, cork, waste tire, waste vinyl, waste plastic, loess, In the case of soil, etc., put into a frame on a square plate is produced by pressing (S30).

When the soundproof plate body 10, the cover plate 20, and the soundproof panel 30 are manufactured as described above, the soundproof panel 30 is accommodated in the soundproof hole 15 of the soundproof plate body 10 (S40). At this time, before the soundproof panel 30 is accommodated in the soundproof hole 15, after the soundproof panel 30 is completely accommodated, sand, sawdust, cork, waste tire, waste vinyl, waste plastic, loess, soil, etc. 40 is injected into the sound insulation hole 15 (S50). Of course, in the case of non-woven fabric, cloth, corrugated cardboard, and the like accommodates a plurality of layers, sand, sawdust, cork, waste tires, waste vinyl, waste plastics, loess, soil, etc. 40 can also be sprayed between each sheet. Can be.

Then, an adhesive is applied to the edge of the soundproof plate body 10, and covers the cover plate 20 to combine the soundproof plate body 10 and the cover plate 20 (S60). At this time, it is preferable that the adhesive uses an aqueous adhesive with low volatility.

In addition, it has already been described that the cover plate may be formed of a thin plate or a thin film when the soundproof plate body 10 and the soundproof panel 30 are sufficient for the noise function.

In addition, when the soundproof plate body 10 and the soundproof panel 30 alone have a sufficient noise function, the function of the cover plate is to prevent the soundproof plate body 10 and the soundproof panel 30 from being separated from each other. An anti-noise material without a cover plate can be constructed. In this case, the soundproof panel body 10 and the soundproof panel 30 may be coupled to each other by taping at least a portion of an outer boundary of the soundproof panel 30 accommodated in the soundproof hole of the soundproof panel body 10.

If the soundproof plate body 10 and the soundproof panel 30 alone have sufficient noise functions, the soundproof plate body 10 and the soundproof panel 30 may be separated from each other, regardless of whether or not the taping process is performed. The soundproof panel body 10 and the soundproof panel 30 may be combined by applying an adhesive to a part or all of at least one surface to which the panel 30 and the soundproof panel body 10 are coupled. Of course, in this case, the cover plate 20 may be absent.

When the adhesive is completely adhered, it is pressurized to a predetermined pressure on the soundproof plate body 10 or the soundproof plate body 10 side and the cover plate 20 side by using a press (S70), so as to the structure of the soundproof plate body 10 or the cover plate 20. Allow cracks to occur to some extent.

On the other hand, in the above-described embodiment, although the sound insulation plate 10 is formed of one member, as shown in Figure 6 to be described later, it may be produced by separating into two parts.

6 is an exploded perspective view of the noise suppression material according to the fourth embodiment of the present invention. The noise suppression material according to the fourth embodiment includes a pair of upper and lower sound insulation plates 120 and 150, and an intermediate sound insulation board 110 disposed between the upper and lower sound insulation plates 120 and 150 and having a plurality of sound insulation holes 115. . The upper and lower sound insulation boards 120 and 150 and the middle sound insulation board 110 are formed of the first sound insulation material as in the first to third embodiments, and the sound insulation holes 115 of the middle sound insulation board 110 are described above. Panel 130 is housed. Here, the upper and lower sound insulation boards 120 and 150 are formed to a thickness of 6 to 20mm, the middle sound insulation board 110 is formed to a thickness of 6 to 15mm, preferably the upper and lower sound insulation plates 120 and 150 are 8 to 15mm thick. The middle soundproof plate 110 is formed to a thickness of 8 to 12mm.

The first soundproofing material used in the fabrication of the upper and lower soundproofing plates 120 and 150 and the intermediate soundproofing plate 110, as in the above-described embodiment, EVA, EPS, PETG, PE, PSP, PP, rubber plate, urethane, etc. Among them, it is most preferable to use styrofoam. As described above, the upper and lower soundproofing plates 120 and 150 and the middle soundproofing plate 110 may use the same material in preparation for deformation after construction.

On the other hand, unlike the first to third embodiments, in the fourth embodiment, a plurality of sound insulation holes 115 are formed in the intermediate sound insulation plate 110 to penetrate the intermediate sound insulation plate 110, and the sound insulation holes 115 are It is formed in a square shape and arranged in a grid.

The soundproof panel 130 accommodated in the soundproof hole 115 of the middle soundproof panel 110, as in the first to the third embodiment, non-woven fabric, paper, including a corrugated paper, scrubber, mineral wool (rock wool), Fabrics including felt, cotton or wool, synthetic resins, sawdust, cork, waste tires, waste vinyl, waste plastics, ocher, soil, etc. are used as they are or through a predetermined process.

Looking at the process of manufacturing the noise preventing material according to this configuration with reference to Figure 7 as follows.

First, the upper and lower soundproofing plates 120 and 150 and the middle soundproofing plate 110 are manufactured using the first soundproofing material (S110). In this case, the manufacturing method is somewhat different depending on what the first soundproofing material is, but if the first soundproofing material is styrofoam, the upper and lower soundproofing plates 120 and 150 and the middle soundproofing panel 110 are manufactured by foaming at high pressure. The upper and lower sound insulation boards 120 and 150 and the middle sound insulation board 110 are different in thickness. When each soundproofing plate is manufactured in this way, the soundproofing hole 115 is formed in the middle soundproofing plate 110 by inserting the middle soundproofing plate 110 between the perforators and operating the device (S120). Then, the middle soundproof plate 110 is seated on the upper portion of the lower soundproof panel 120 (S130), and the lower soundproof panel 120 and the middle soundproof panel 110 are coupled by taping or bonding. In this case, when bonding, it is preferable to use an aqueous adhesive having low volatility according to the characteristics of the first soundproofing material.

In such a state that the lower soundproof panel 120 is bonded, the soundproof panel 130 is accommodated in the soundproof hole 115 (S140), and sand, sawdust, cork, waste tire, waste vinyl, waste plastic, loess, soil on the top. A powder such as the above is injected into the sound insulation hole 15.
